Understanding factors that contribute to a student’s selection of an exercise science-related major is important to student success, higher education and industry. This study sought to 1) better understand why undergraduate students study an exercise science-related major, 2) determine whether positive influences to study an exercise science-related major differ by academic classification, and 3) identify what student’s aspirations are after graduation. Department administrators from four-year colleges and universities offering an exercise science-related major in the Northwest Region of the United States (i.e., Idaho, Montana, Oregon, and Washington) were contacted. Cooperating department administrators were given self-reported questionnaires for students to complete using a snowball sampling method. A total of 388 participants completed the questionnaire. Interest in the subject and potential job opportunities were the most common reasons to study an exercise science-related major. Self-reported Holland’s codes identified that realistic and social personalities were most prevalent among participants. Seniors rated a friend’s influence and college advisors as stronger influences to study an exercise science-related major compared to freshmen. Pay in the field was a stronger influence for freshmen to study an exercise science-related major than for fifth-year seniors, whereas freshmen were less influenced by introductory courses to study an exercise-science related major than fifth-year seniors. The majority of undergraduate students studying an exercise science-related major planned on attending graduate school after completing their baccalaureate degree. These findings can be used to help guide undeclared students and better serve undergraduates enrolled in an exercise science-related major. PMID:28966716

Early adulthood is related to changes in lifestyle that negatively affect body weight and health. The aim of the study was to determine the effect of exercise changes on the development of weight and body composition in college students.Sixty-one randomly selected dental (ZMS) and 53 sport students (SLS) were accompanied over 5 years. Body mass, fat and lean body mass (LBM) were determined via DXA-technique. Exercise and physical activity were assessed by questionnaires and interviews.All exercise indices significantly increased in the SLS and significantly decreased in the ZMS. Physical activity slightly increased in both groups. Both cohorts comparably gained body mass, however, the increase in the SLS group can be attributed to LBM-changes with minor changes of fat-mass (2.4 % ± 3.3 % vs. 0.1 ± 1.0 %) whereas ZMS gained fat and LBM in a proportion of 2:1.Maintenance/increase of exercise compensate the negative effects of lifestyle changes on body composition during young adulthood.

SOLAR ROTATION: A Laboratory Exercise from Project CLEA and the GONG Project

NASA Astrophysics Data System (ADS)

Marschall, L. A.; Sudol, J. J.; Snyder, G. A.

2002-12-01

Digital images from the GONG Project provide a nearly continuous record of sunspots that are ideal for determining the rate of rotation of the Sun. A new laboratory exercise from Project CLEA provides students with the capability to access an archive of 368 images of the Sun obtained at GONG solar telescopes between January 1, 2002 and April 30, 2002, during a period near solar maximum when large numbers of spots were daily visible on the sun. The resolution of each image is about 2.5 arcsec per pixel (or about 0.25 degree in longitude and latitude at the center of the solar disk). Because these images have such exquisite spatial and temporal resolution, they are the best images to date from which students can determine the solar rotation rate. CLEA software for this exercise allows students to select images by date and time, to overlay a coordinate grid on the image, and to record the latitudes and longitudes of sunspots. This data can be tabulated and analyzed with the software to determine solar rotation rates. The expected precision in the solar rotation rates is +/- 3 hours. Students will also have the ability to combine their chosen images into a digital movie showing the solar rotation. The exercise includes a student workbook and a technical manual, as well as a CD-rom of the data and the software. This exercise was produced with funding from the National Science Foundation and Gettysburg College and with the support of the GONG Project at the National Solar Observatory.

2015-12-01

For decades, role-play and simulation exercises have been utilized for learning and policy decision making. While the power of Model UN simulations in building first-person experience and understanding of complex international issues is well known, the effectiveness of simulations for inspiring citizen engagement in scientific public-policy issues is little studied. My work hypothesizes that climate-change negotiation simulations can enhance students' scientific literacy and policy advocacy. It aims to determine how age and gender influence the responsiveness of students to such simulations. During the 2015 fall semester, I am conducting World Climate exercises for fellow graduate and undergraduate students at San Francisco State University. At the end of the exercise, I will have collected the responses to an anonymous questionnaire in which the participants indicate age and gender. The questionnaire asks participants to describe their hopes and fears for the future and to propose public and personal actions for achieving a strong climate change agreement. I am tracking differences to determine whether participants' age and gender correlate with particular patterns of feeling and thinking. My future research will aim to determine whether and how strongly the World Climate Exercise has affected participants' actual policy engagement. This work will also reflect on my experiences as a World Climate facilitator. I will describe the facilitation process and then discuss some of my observations from the sessions. I will specify the challenges I have encountered and suggest strategies that can strengthen the learning process. World Climate is a computer-simulation-based climate change negotiations role-playing exercise developed by Climate Interactive in partnership with the System Dynamics Group at the MIT Sloan School of Management.

The impact of collaborative groups versus individuals in undergraduate inquiry-based astronomy laboratory learning exercises

NASA Astrophysics Data System (ADS)

Sibbernsen, Kendra J.

One of the long-standing general undergraduate education requirements common to many colleges and universities is a science course with a laboratory experience component. One of the objectives frequently included in the description of most of these courses is that a student will understand the nature and processes of scientific inquiry. However, recent research has shown that learners in traditional undergraduate science laboratory environments are not developing a sufficiently meaningful understanding of scientific inquiry. Recently, astronomy laboratory activities have been developed that intentionally scaffold a student from guided activities to open inquiry ones and preliminary results show that these laboratories are successful for supporting students to understand the nature of scientific inquiry (Slater, S., Slater, T. F., & Shaner, 2008). This mixed-method quasi-experimental study was designed to determine how students in an undergraduate astronomy laboratory increase their understanding of inquiry working in relative isolation compared to working in small collaborative learning groups. The introductory astronomy laboratory students in the study generally increased their understanding of scientific inquiry over the course of the semester and this held true similarly for students working in groups and students working individually in the laboratories. This was determined by the examining the change in responses from the pretest to the posttest administration of the Views of Scientific Inquiry (VOSI) survey, the increase in scores on laboratory exercises, and observations from the instructor. Because the study was successful in determining that individuals in the astronomy laboratory do as well at understanding inquiry as those who complete their exercises in small groups, it would be appropriate to offer these inquiry-based exercises in an online format.

Exercisers' perceptions of their fitness instructor's interacting style, perceived competence, and autonomy as a function of self-determined regulation to exercise, enjoyment, affect, and exercise frequency.

PubMed

Puente, Rogelio; Anshel, Mark H

2010-02-01

The primary purpose of the present investigation was to test the hypothesis, derived from Self-Determination Theory (SDT), that an individual's perceived competence and autonomy mediate the relationship between the exercisers' perception of their instructor's interaction style and the exercisers' motivation to exercise. A secondary purpose was to identify the affective and behavioral outcomes derived from self-determined regulation. It was hypothesized that SDT would significantly explain and predict exercise behavior. Participants consisted of 238 college students, 103 males and 135 females (M age = 20.4 years, SD = 2.16), who volunteered to participate in the study. They were asked to complete a battery of questionnaires measuring instructor's interacting style, self-regulation to exercise, perceived autonomy and competence, enjoyment, positive and negative affect, and exercise frequency. Using structural equation modeling with observed variables, the results showed that perceived competence and autonomy mediated the relationship between perceived instructor's interacting style and self-determined regulation. It was also found that self-determined regulation was significantly related to exercise enjoyment, positive affect, and exercise frequency. It was concluded that understanding the motivational factors and emotional and behavioral consequences of physical activity will partially explain an individual's motives to engage regularly in exercise.

The relationship between exercise motives and psychological well-being.

Maltby, J; Day, L

2001-11-01

The aim of the present study was to use the self-determination model of exercise motives to examine the relationship between extrinsic and intrinsic motives for exercise and a number of measures of psychological well-being. Undergraduate students purporting to exercise regularly (N = 227; 102 men, 125 women) were split into 2 groups: those exercising for less than 6 months and those exercising for 6 months or more. The respondents were asked to complete measures of exercise motivation, self-esteem, psychological well-being, and stress. Among individuals exercising for less than 6 months, a number of extrinsic motivations for exercise were significantly related to poorer psychological well-being. Among individuals exercising for 6 months or more, a number of intrinsic motivations were significantly related to better psychological well-being. The present findings suggest that researchers can use self-determination theory to understand the relationship between exercise motivation and psychological well-being.

Childhood physical activity (PA) is an important determinant of health in adults which is influenced by the environment in and outside of home. We aimed to determine the contribution of parental and school factors on student's PA in this study. This cross sectional study was conducted on students attending public and private schools in Hyderabad, Pakistan. A random sample of 246 girls and 255 boys in grade six to ten were selected from ten schools. The PA was assessed through face to face interviews by using the adapted School Health Action Planning and Evaluation System (SHAPES) questionnaire. 40% of the students either walked to or rode on a cycle to travel to their school and 62% students performed individual exercises after school. They spent 6.2 and 5.3 hours on moderate and hard PA per week. About 57% of the mothers and 47% fathers of the students did some mild to moderate exercise 4 times in the week prior to the interview. Students were physically active if they lived in a nuclear family, had believed they had better athletic ability, participated in sports in and out of school and performed moderate exercises (p < 0.05). In conclusion parental support to PA was significantly associated with students' being physically active both within and outside schools.

2010-02-01

Grounded in self-determination theory (SDT; Deci & Ryan, 2000), the current study explored whether physical education (PE) students' psychological needs and their motivational regulations toward PE predicted mean differences and changes in effort in PE, exercise intentions, and leisure-time physical activity (LTPA) over the course of one UK school trimester. One hundred and seventy-eight students (69% male) aged between 11 and 16 years completed a multisection questionnaire at the beginning, middle, and end of a school trimester. Multilevel growth models revealed that students' perceived competence and self-determined regulations were the most consistent predictors of the outcome variables at the within- and between-person levels. The results of this work add to the extant SDT-based literature by examining change in PE students' motivational regulations and psychological needs, as well as underscoring the importance of disaggregating within- and between-student effects.

This paper discusses a Fermi-problem exercise through which I take students in several of my college courses. Students work in teams, determining the average daily Caloric needs per person. Then they use insolation values to determine the size of a collection area needed to absorb the previously determined daily energy requirements. Adjustments to the size of the collection area are made based on energy absorption per biological trophic level, as well as the consideration that most diets are a mixture of plant- and animal-derived elements. Finally, using the total amount of farmland available on the planet, students calculate a maximum population value. Although the maximum population values derived herewith should not be considered authoritative, the exercise has three beneficial purposes: 1) a chance to talk about the modeling process and extrapolations, 2) an unexpected application of physics to social contexts, and 3) raising student awareness of population and energy issues.

Effect of an exercise and weight control curriculum: views of obesity among exercise science students.

Richardson, Laura A; Fister, Carrie L; Ramlo, Susan E

2015-06-01

Awareness of effective weight management strategies is necessary to prepare exercise science students for future work with obesity. Exercise science faculty members developed a course related to exercise as a therapeutic tool and options available for weight loss. The purpose of the present study was to investigate student views of weight management and obesity, which can be a difficult task using traditional methods such as Likert scale surveys. To investigate student views relative to the course content, Q methodology, which is a mixed-method research approach, was used at the beginning and end of the course. Students completed a Q sort, ranking 44 statements related to obesity in accordance to their own points of view. The pretest/posttest design enabled an opportunity to determine if course goals were accomplished and if student perceptions related to obesity were transformed. Factor analysis of precourse sorts revealed that students possessed a naïve singular view of weight-related concepts. Analysis of sorts at course completion resulted in a two-factor solution revealing changes in perspective; some students took on a health professional type of view, whereas others demonstrated antifat views. In conclusion, the findings revealed key variables that should be addressed in curricula involving therapeutic obesity interventions. An improved curriculum based on these results should better encourage students to develop a broad comprehension of multifactorial causes and treatment for weight management and obesity. Implementing the use of Q methodology may serve as a valuable asset to measure and evaluate subjectivity of obesity discrimination. Antifat attitudes among exercise science students may influence future clients' potential achievements. Copyright © 2015 The American Physiological Society.

Lack of physical activity is a contributor to the obesity epidemic and is speculated to relate to reduced academic performance; however, this link has yet to be examined within the college population. The purpose of this study in a group of undergraduate students, was to determine if aerobic exercise activity was related to academic performance. The participants for this study included 740 students at multiple universities enrolled in nursing and kinesiology studies. The participants completed the Leisure and Physical Activity Questionnaire. Pearson's χ(2) analysis revealed differences in grade point average with aerobic activity (χ(2) = 44.29, P ≤ 0.001) as well as a trend toward differences in grade point average with weightlifting activity (χ(2) = 22.69, P = 0.61). Based on these findings it can be suggested that college students engage in greater aerobic exercise.

To determine the effectiveness of habitual exercise on the health promotion of college students, we measured the body composition and physical fitness of female nursing students before (Pre) and after (Post) an 8-week low-intensity exercise intervention. We also conducted a questionnaire survey of their mental health condition before and at every 4 weeks during the intervention. The quantity of physical exercise increased (P < 0.0001) from 0.9 ± 0.2 METs･hr/week in the pre-intervention period to 6.6 ± 0.7 METs･hr /week during the intervention period. The exercise intervention did not alter the body weight, but decreased the body fat (Pre, 26.8 ± 0.5%; Post, 24.9 ± 0.5%, P < 0.01) and increased the whole-body muscle mass (Pre, 69.1 ± 0.5%; Post, 70.8 ± 0.4%, P < 0.01). The results of physical fitness tests showed that the intervention promoted muscular strength, muscular endurance, flexibility, agility, and muscular power. The scores for mental health were significantly raised by the intervention. These results suggest that habitual exercise for 8 weeks was effective for the promotion of physical and mental health in female nursing students.

2014-07-01

This paper describes a physics laboratory exercise for determining the coefficient of static friction between two surfaces. The circular motion of a coin placed on the surface of a rotating turntable has been studied. For this purpose, the motion is recorded with a high-speed digital video camera recording at 240 frames s-1, and the videos are analyzed using Tracker video-analysis software, allowing the students to dynamically model the motion of the coin. The students have to obtain the static friction coefficient by comparing the centripetal and maximum static friction forces. The experiment only requires simple and inexpensive materials. The dynamics of circular motion and static friction forces are difficult for many students to understand. The proposed laboratory exercise addresses these topics, which are relevant to the physics curriculum.

The purpose of this study was to identify some psychological determinants of exercise adherence on which public school physical education programs may have an impact. Data were collected twice, once representing a structured physical education classroom setting (N = 132), and later representing an unstructured summer vacation exercise setting (N = 110). Male and female physical education students at a large suburban high school completed five questionnaires which represented four psychological variables (self-motivation, perceived control, personality/sport congruence, and perceived self-competency), and one physical activity variable (exercise adherence) in both of the two data-collection periods. The results indicated that Perceived Romantic Appeal was predictive of male exercise adherence while Perceived Athletic Competency, Perceived Global Self-Worth, and Perceived Physical Appearance were predictive of female exercise adherence. None of the psychological predictor variables was significant for competitive subjects in either exercise setting, yet Perceived Romantic Appeal and Personality/Sport Congruence were predictive of noncompetitive subjects' exercise adherence in the structured and unstructured settings, respectively.

Background and aims The study explored the mediating role of forms of passion in the relationship between motivational regulations in exercise and exercise addiction (EA). Methods A total of 485 university students (368 males and 117 females; M age  = 20.43, SD = 3.21) completed a questionnaire measuring the frequency and intensity of exercise, motivational regulations in exercise, passion for exercise, and EA. Controlling the effects of age, frequency, and intensity of practice, the relationships between the study variables were examined though a path analysis. Results Both self-determined and non-self-determined forms of motivation showed positive association with EA. The forms of motivation with greatest predictive power for EA were introjected and integrated regulations. Both forms of motivation had positive direct and indirect effects through obsessive passion (OP) on EA; however, integrated regulation also showed negative indirect effects through harmonious passion on EA. Conclusions Both forms of passion and, especially, OP, seem to affect how motivational regulations are associated with EA. These findings clarify the association found in previous studies between self-determined forms of motivation and EA.

To determine the impact of performing critical-thinking and reflection assignments within interdisciplinary learning teams in a biochemistry course on pharmacy students' and prospective health professions students' collaboration scores. Pharmacy students and prospective medical, dental, and other health professions students enrolled in a sequence of 2 required biochemistry courses. They were randomly assigned to interdisciplinary learning teams in which they were required to complete case assignments, thinking and reflection exercises, and a team service-learning project. Students were asked to complete the Scale of Attitudes Toward Physician-Pharmacist Collaboration prior to the first course, following the first course, and following the second course. The physician-pharmacist collaboration scores of prospective health professions students increased significantly (p<0.001). Having prospective health professions students work in teams with pharmacy students to think and reflect in and outside the classroom improves their attitudes toward physician-pharmacist collaboration.

To determine the impact of My Student Body (MSB)-Nutrition, an Internet-based obesity prevention program for college students. Three hundred and twenty ethnically diverse undergraduate students were randomly assigned to 1 of 3 conditions: MSB-Nutrition program, an on-campus weight management course, and a comparison group. Students completed baseline and follow-up surveys regarding their nutrition and physical activity behaviors, self-efficacy, stress, attitudes, and body weight. Compared with the on-campus course and a comparison group, the MSB-Nutrition program increased fruit and vegetable consumption, reduced stress, and increased fruit and vegetable self-efficacy but had no significant effect on students' exercise self-efficacy, exercise behavior, or weight loss. The MSB-Nutrition program was effective in changing students' nutrition behaviors but had no effect on physical activity behaviors or weight loss. Suggestions for improving Internet-based interventions aimed at decreasing obesity rates among college students are offered.

Roemer Redux: A Virtual Observational Exercise on Jupiter's Moons and the Speed of Light from Project CLEA

2009-01-01

Project CLEA announces a new laboratory exercise which allows students to determine the speed of light by timing eclipses of Jupiter's moon Io. The experiment is similar to Ole Roemer's classic 17th Century work which established, for the first time, that light did not travel through space instantaneously. Students view a simulated telescopic view of Jupiter and its satellites, similar to that used in the CLEA exercise, The Revolution of the Moons of Jupiter. After identifying Io, they record the precise time when the moon enters Jupiter's shadow at a date about two months after conjunction. Using the recorded time of this eclipse and the known period of Io, students predict the time of an eclipse near opposition and then record the observed time of that eclipse. The discrepancy between the predicted and observed times, along with the difference in the distance between Earth and Jupiter at the two eclipses yields a value of the speed of light accurate to about 10%. Software provided with the exercise enables students to calculate predicted times and Earth/Jupiter distances, as well as to analyze the time discrepancy and to visualize the logic of the analysis. A student manual, including historical and scientific background of the exercise is provided. Our poster will present examples of the screens and manuals for the exercise and will discuss the limits of accuracy of the method and sources of error.

Medical students often experience difficulty comprehending anatomic relationships of complex operations to which they are exposed during surgical clerkship. Pancreaticoduodenectomy, the Whipple procedure, is one such operation. Although video recordings are available to facilitate the learning of the Whipple procedure, commercially available tapes are not self-explanatory to the uninitiated. Since we have previously demonstrated that third-year medical students could learn the operative steps of inguinal herniorraphy by a paper-cutting exercise, we set out to determine whether an exercise of similar design could enhance a student's comprehension of the Whipple procedure. Using Adobe Illustrator 5.5 for MacIntosh, an exercise was developed on a 8.5 x 11-inch paper that could be distributed to students for self-administration. The exercise was performed using a #15 scalpel or an iris scissors. Thirty-seven students were randomized into two groups. Each student received a pretest of questions focusing on the Whipple procedure. Group I was shown an 18-minute commercially available teaching video on the Whipple procedure. Group II was given the Whipple origami exercise, which required 20 minutes to complete. A first posttest was administered to each group. Next, the groups switched exercises, and a second posttest was administered. There was no significant difference between the groups' pretest scores (two-tailed t test, P = 0.290). Group I improved its score from an average of 64.21 (SD 14.27) to 67.89 (SD 13.16) after watching the video, and further to 77.89 (SD 14.37) after completing the paper-cut exercise. Group II improved from 60.00 (SD 9.43) to 78.95 (SD 11.00) after performing the paper-cut, but derived no additional measurable benefit from watching the video, average score 74.74 (SD 18.37). After the first exercise, students who performed the paper-cut showed a significantly greater improvement in test scores compared with students who saw the video (P = 0.0035 by Mann-Whitney U). After both groups had completed the exercises, the mean changes from baseline were no longer significantly different (P = 0.58 by Mann-Whitney U). As a single educational intervention, the paper-cut exercise was a more effective teaching device than the video in the given time frame. The origami model may be generalized to a variety of surgical procedures and appears to be a valuable adjunct to traditional teaching.

2011-01-01

From a convenience sample consisting of junior level nursing students enrolled in a research class at a southern Historically Black College and University (HBCU), this pilot study investigated the percent of participants who were overweight as determined by Body Mass Index (BMI) measurements, and the percent satisfied with their body image as measured by the Strunkard Body Image Scale. BMI measurements were correlated with self esteem, body image, self care, and self efficacy in the regulation of eating habits and exercise regimens. The study found that students with greater BMIs had lower self efficacy beliefs about regulating their exercise habits. Self care, post the self directed intervention, significantly correlated with the pre and post intervention scores of self efficacy to regulate exercise, and with the post intervention scores of self efficacy to regulate eating habits. However, the study found that students' self care capacity was significantly different at the end of the study period.

A pre-tested semi structured questionnaire was self administered to the students after taking their consent. The data included socio-demographic characteristics, life style, exercise, dietary habits and family history of diabetes mellitus. The collected data was analyzed by statistical program SPSS version 11. Out of the total participants, 53.4% were male and 46.6% were female students. The mean age was 20 +/- 1.58 years. The average income of the household of students was 50,000 Pakistani rupees per month. Only 7% students were tobacco users. About 33% students had a history of diabetes mellitus among their parents. Nearly 97% reported consumption of junk food while 60% reported use of whole grain food in their diet. Seventy percent students walked 30 minutes and 47% exercised daily. According to the body mass index, 58.3% students were of normal weight and 41.7% were overweight. No significant difference was found among male and female students when dietary habits and life style were compared by sex. Junk food and soft-drink consumption was associated with being overweight. Eating whole grain food and doing exercise showed a protective association against overweight. Unhealthy lifestyle and poor dietary habits were highly prevalent in the overweight study population. Type-2 diabetes mellitus was common among parents and grandparents of the students making them prone to this disorder. Our study concluded that dietary and exercise counselling is necessary as a preventive strategy.

Gaining a Better Understanding of Estuarine Circulation and Improving Data Visualization Skills Through a Hands-on Contouring Exercise

NASA Astrophysics Data System (ADS)

Mailloux, B. J.; Kenna, T. C.

2008-12-01

The creation and accurate interpretation of graphs is becoming a lost art among students. The availability of numerous graphing software programs makes the act of graphing data easy but does not necessarily aide students in interpreting complex visual data. This is especially true for contour maps; which have become a critical skill in the earth sciences and everyday life. In multiple classes, we have incorporated a large-scale, hands-on, contouring exercise of temperature, salinity, and density data collected in the Hudson River Estuary. The exercise allows students to learn first-hand how to plot, analyze, and present three dimensional data. As part of a day-long sampling expedition aboard an 80' research vessel, students deploy a water profiling instrument (Seabird CTD). Data are collected along a transect between the Verrazano and George Washington Bridges. The data are then processed and binned at 0.5 meter intervals. The processed data is then used during a later laboratory period for the contouring exercise. In class, students work in groups of 2 to 4 people and are provided with the data, a set of contouring instructions, a piece of large (3' x 3') graph paper, a ruler, and a set of colored markers. We then let the groups work together to determine the details of the graphs. Important steps along the way are talking to the students about X and Y scales, interpolation, and choices of contour intervals and colors. Frustration and bottlenecks are common at the beginning when students are unsure how to even begin with the raw data. At some point during the exercise, students start to understand the contour concept and each group usually produces a finished contour map in an hour or so. Interestingly, the groups take pride in the coloring portion of the contouring as it indicates successful interpretation of the data. The exercise concludes with each group presenting and discussing their contour plot. In almost every case, the hands-on graphing has improved the "students" visualization skills. Contouring has been incorporated into the River Summer (www.riversumer.org, http://www.riversumer.org/) program and our Environmental Measurements laboratory course. This has resulted in the exercise being utilized with undergraduates, high-school teachers, graduate students, and college faculty. We are in the process of making this curricular module available online to educators.

Introducing AC inductive reactance with a power tool

NASA Astrophysics Data System (ADS)

Bryant, Wesley; Baker, Blane

2016-09-01

The concept of reactance in AC electrical circuits is often non-intuitive and difficult for students to grasp. In order to address this lack of conceptual understanding, classroom exercises compare the predicted resistance of a power tool, based on electrical specifications, to measured resistance. Once students discover that measured resistance is smaller than expected, they are asked to explain these observations using previously studied principles of magnetic induction. Exercises also introduce the notion of inductive reactance and impedance in AC circuits and, ultimately, determine self-inductance of the motor windings within the power tool.

Marshall, Pamela A

2007-01-01

In our Fundamentals of Genetics lab, students perform a wide variety of labs to reinforce and extend the topics covered in lecture. I developed an active-learning lab to augment the lecture topic of mutagenesis. In this lab exercise, students determine if a compound they bring from home is a mutagen. Students are required to read extensive background material, perform research to find a potential mutagen to test, develop a hypothesis, and bring to the lab their own suspected mutagen. This lab uses a specially developed strain of Saccharomyces cerevisiae, D7, to determine if a compound is a mutagen. Mutagenesis of the D7 genome can lead to a scorable alteration in the phenotypes of this strain. Students outline and carry out a protocol for treatment of the yeast tester strain, utilizing the concept of dose/response and positive and negative controls. Students report on their results using a PowerPoint presentation to simulate giving a scientific presentation. The students' self-assessment of their knowledge indicated that, in all cases, the students felt that they knew more about the assay, mutagenesis, and the relationship between genotype and phenotype (P < 0.05) after completing the exercise.

Biondolillo, Mathew J; Pillemer, David B

2015-01-01

This study tested a novel memory-based experimental intervention to increase exercise activity. Undergraduate students completed a two-part online survey ostensibly regarding college activity choices. At Time 1, they completed questionnaires that included assessments of exercise-related attitudes, motivation and self-reported behaviours. Next, they described a memory of a positive or negative experience that would increase their motivation to exercise; students in a control condition did not receive a memory prompt. Finally, they rated their intentions to exercise in the future. Eight days following Time 1, students received a Time 2 survey that included an assessment of their self-reported exercise during the prior week. Students in the positive memory condition reported higher levels of subsequent exercise than those in the control condition; students in the negative memory condition reported intermediate levels of exercise. Activating a positive motivational memory had a significant effect on students' self-reported exercise activity even after controlling for prior attitudes, motivation and exercise activity.

Abstract Based on the self-determination theory (Deci and Ryan, 1985, 2000), the purpose of this study was to examine the effects of exercise goal contents on exercise addiction, taking into account the mediating effects of passion for exercise. A total of 384 university students (284 men and 100 women; Mage = 20.31, SD = 3.10) completed a questionnaire that measured exercise frequency and intensity, exercise goal contents (e.g. intrinsic: social affiliation, health management, skill development; extrinsic: image and social recognition), passion for exercise (e.g. harmonious and obsessive), and exercise addiction. After controlling the exercise frequency and intensity effects, results showed that goal contents did not directly predict exercise addiction. However, mediation analysis showed that goal contents predicted addiction through passion for exercise. These results support a motivational sequence in which extrinsic versus intrinsic goals influence exercise addiction because such goals are positively associated with obsessive passion for exercise and negatively associated with harmonious passion.

To describe the physical activity (PA) levels and counseling attitudes of Canadian undergraduate medical students. Online or paper survey. The University of British Columbia (UBC). Fourth-year medical students at UBC from 2007 to 2010. Physical activity levels, relationship between exercise behaviour and attitudes toward counseling, and student perception of training in the area of exercise prescription. A total of 546 out of 883 students participated in the survey (62% response rate). Sixty-four percent of students met the Canadian Society for Exercise Physiology 2011 recommendations for PA. Attitudes toward healthy living were related to PA levels, but the rate of counseling patients about exercise was not; however, students who engaged in more strenuous PA were more likely to perceive exercise counseling as being highly relevant to future clinical practice (P = .018). Overall, 69% of students perceived exercise counseling to be highly relevant to clinical practice, but 86% thought that their training in this area was less than extensive. Fourth-year UBC medical students engage in more strenuous PA than average age-matched Canadians, which affects their attitudes toward perceived future counseling practices. Encouraging more student participation in strenuous PA and encouraging academic training in the area of exercise counseling might be important next steps in preparing future physicians to effectively prescribe exercise to their patients.

2015-12-01

The aim of this study was to investigate the effects of exercise dependence on the psychological health of Chinese college students. A total of 1601 college students from three universities in Hunan, China, were selected as research subjects. Several measurement scales, including the Exercise Addiction Inventory, the State-Trait Anxiety Inventory, the Center for Epidemiologic Studies Depression Scale, and the Subjective Well-being Scale, were used to survey the psychological health problem of these students and to analyze the effects of exercise dependence on their psychological health. Exercise dependence, based on the structural equation model analysis, can positively influence state anxiety (P<0.05), depression (P<0.05), and subjective well-being (P<0.05) of Chinese students. By contrast, exercise dependence negatively influences students' self-satisfaction (P<0.05), social behavior (P<0.05), and vigor (P<0.05). Exercise dependence adversely affects the psychological health of college students. Further research using multi-dimensional exercise addiction scales should be conducted to identify all the negative effects of exercise addiction factors on psychological health.

Hallgren, Richard C; Parkhurst, Perrin E; Monson, Carol L; Crewe, Nancy M

2002-03-01

To evaluate the effectiveness of a Web-based interactive teaching tool that uses self-assessment exercises with real-time feedback to aid students' learning in a gross anatomy class. A total of 107 of 124 first-year medical students at one school were enrolled in the study. Students were divided into three groups: Group 1 (n = 63) received introductory material and activated their Web-based accounts; Group 2 (n = 44) received introductory material but did not activate their Web-based accounts; and Group 3 (n = 17) were not enrolled in the study and received no introductory material. Students in Group 1 had access to a graphic showing the locations of anatomic landmarks, a drill exercise, and a self-evaluation exercise. Students' ability to identify the anatomic landmarks on a 30-question midterm and a 30-question final exam were compared among the groups. The mean scores of students in Group 1 (midterm = 28.5, final = 28.1) were significantly higher than were the mean scores of students in Group 2 (midterm = 26.8, p <.001; final = 26.9, p <.017) and Group 3 (midterm = 24.8, p <.001; final = 26.4, p <.007). The Web-based tool was effective in improving students' scores on anatomic landmark exams. Future studies will determine whether the tool aids students in identifying structures located in three-dimensional space within regions such as the cranium and the abdominal cavity.

Anxiety responses to maximal exercise testing.

PubMed Central

O'Connor, P J; Petruzzello, S J; Kubitz, K A; Robinson, T L

1995-01-01

The influence of maximal exercise testing on state anxiety was examined in three separate studies. Highly trained male distance runners (Study 1, n = 12) as well as college students with average (Study 2, n = 16) and below average (Study 3, n = 32) physical fitness levels completed graded maximal exercise tests. This last group was also randomly assigned to either a control or an 8 week training programme in order to determine the effect of increased fitness on the psychological responses to maximal exercise testing. Physical fitness was determined by the measurement of maximal oxygen uptake. State anxiety (State-Trait Anxiety Inventory) was assessed before and from 2-15 min following exercise. It was found that the state anxiety responses to maximal exercise testing were not influenced by re-testing or by 8 weeks of endurance training. Across the three study groups, the anxiety response was variable during the first 5 min following exercise testing; increases, decreases and no changes in anxiety were observed when compared to pre-exercise levels. The anxiety response to maximal exercise appeared to be dependent on the pre-exercise anxiety levels as well as the timing of the post-exercise assessments. It is concluded that maximal exercise testing can be associated with negative mood shifts during the first 5 min after exercise; however, this response is transitory and followed by positive mood shifts 10-15 min following such tests.

Desktop Parallax and Proper Motion: A Laboratory Exercise on Astrometry of Asteroids from Project CLEA

NASA Astrophysics Data System (ADS)

Marschall, L. A.; Snyder, G. A.; Good, R. F.; Hayden, M. B.; Cooper, P. R.

1998-12-01

Students in introductory and advanced astronomy classes can now experience the process of discovering asteroids, can measure proper motions, and can actually see the parallax of real astronomical objects on the screen, using a new set of computer-based exercises from Project CLEA. The heart of the exercise is a sophisticated astrometry program "Astrometry of Asteroids", which is a restricted version of CLEA's research software "Tools for Astrometry" described elsewhere at this meeting. The program, as used in the teaching lab, allows students to read and display digital images, co-align pairs of images using designated reference stars, blink and identify moving objects on the pairs, compare images with charts produced from the HST Guide Star Catalog (GSC), and fit equatorial coordinates to the images using designated reference stars from the GSC. Complete technical manuals for the exercise are provided for the use of the instructor, and a set of digital images, in FITS format, is included for the exercise. A student manual is provided for an exercise in which students go through the step-by-step process of determining the tangential velocity of an asteroid. Students first examine a series of images of a near-earth asteroid taken over several hours, blinking pairs to identify the moving object. They next measure the equatorial coordinates on a half-dozen images, and from this calculate an angular velocity of the object. Finally, using a pair of images of the asteroid taken simultaneously at the National Undergraduate Research Observatory (NURO) and at Colgate University, they measure the parallax of the asteroid, and thus its distance, which enables them to convert the angular velocity into a tangential velocity. An optional set of 10 pairs of images is provided, some of which contain asteroids, so that students can try to "find the asteroid" for themselves. The software is extremely flexible, and though materials are provided for a self-contained exercise, teachers can adapt the material to a wide variety of uses. The software and manuals are currently available on the Web. Project CLEA is supported by grants from Gettysburg College and the National Science Foundation.

Predictors of physical activity and barriers to exercise in nursing and medical students.

PubMed

Blake, Holly; Stanulewicz, Natalia; Mcgill, Francesca

2017-04-01

To investigate physical activity levels of nursing and medicine students, examine predictors of physical activity level and examine the most influential benefits and barriers to exercise. Healthcare professionals have low levels of physical activity, which increases their health risk and may influence their health promotion practices with patients. We surveyed 361 nursing (n = 193) and medicine (n = 168) students studying at a UK medical school. Questionnaire survey, active over 12 months in 2014-2015. Measures included physical activity level, benefits and barriers to exercise, social support, perceived stress and self-efficacy for exercise. Many nursing and medicine students did not achieve recommended levels of physical activity (nursing 48%; medicine 38%). Perceived benefits of exercise were health related, with medicine students identifying additional benefits for stress relief. Most notable barriers to exercise were as follows: lack of time, facilities having inconvenient schedules and exercise not fitting around study or placement schedules. Nursing students were less active than medicine students; they perceived fewer benefits and more barriers to exercise and reported lower social support for exercise. Physical activity of nursing and medicine students was best predicted by self-efficacy and social support, explaining 35% of the variance. Physical activity should be promoted in nursing and medicine students. Interventions should aim to build self-efficacy for exercise and increase social support. Interventions should be developed that are targeted specifically to shift-working frontline care staff, to reduce schedule-related barriers to exercise and to increase accessibility to workplace health and well-being initiatives. © 2016 John Wiley & Sons Ltd.

2010-01-01

Participation in appropriate exercise can help reduce the risk of falls and falls injury in older people. Delivery of population-level exercise interventions requires an expert workforce with skills in development and delivery of group exercise programs and prescription of individually targeted exercise. This study assessed the current knowledge of university exercise science students (as future exercise professionals) across different levels of study. A structured survey designed to assess knowledge in relation to falls in older people and exercise prescription for falls prevention was administered during second, third and fourth year lectures in seven Australian universities. Students' knowledge was assessed as the percent of correct responses. Overall, 566 students completed the survey and knowledge levels increased significantly with study year. Mean knowledge levels were significantly <70%, indicating limited knowledge. They were lowest for falls risk factor questions and highest for issue/cost related questions in second and third year students. Fourth year students had best knowledge about falls interventions and this was the only group and topic with a mean score >70%. In conclusion, knowledge about falls and exercise prescription for falls prevention in current students does not meet a desired competency level of 70% and is therefore insufficient to ensure an adequately equipped future workforce in this area. There is a clear need for the development and widespread delivery of an evidence-based "exercise for falls prevention" curriculum module for exercise professionals.

Association Between Dental Student-Developed Exam Questions and Learning at Higher Cognitive Levels.

PubMed

Gonzalez-Cabezas, Carlos; Anderson, Olivia S; Wright, Mary C; Fontana, Margherita

2015-11-01

New dental accreditation standards emphasize that graduates must be competent in the use of critical thinking (a high cognitive-level skill). Despite this new standard, most written assessments in dental school courses are still based on low cognitive-level questions. The aim of this study was to determine if an exercise that allows students to collaboratively write exam questions would help cultivate higher cognitive levels of learning. To evaluate this exercise at one U.S. dental school, the cognitive level (according to Bloom's taxonomy) of multiple-choice exam questions and students' scores across two cohorts in a cariology course were compared. This evaluation took place using a control group in which questions were instructor-generated and an intervention group in which students worked in groups to develop questions. All students in one first-year class participated in the intervention group (n=104); all students in the first-year class two years earlier served as the control group (n=106). Among students in the intervention group, the response rate to a post-intervention survey measuring students' attitudes about the experience was 70% (N=73). The results showed that the students generating their own assessments developed higher cognitive-level exam questions than the instructor-generated assessments. The intervention group (with student-generated assessments) also performed as well or better on tests compared to the control group (with instructor-generated assessments). In the intervention group survey, the vast majority of students agreed that the exercise was helpful for their overall learning experience, but working in teams was said to be the least valuable component of the activity for their learning. This study suggests that student-driven, collaborative assessments can be an important tool for building critical thinking skills in dental classrooms and that it may be worthwhile to expand this type of exercise into other courses.

Phonetics exercises using the Alvin experiment-control software.

PubMed

Hillenbrand, James M; Gayvert, Robert T; Clark, Michael J

2015-04-01

Exercises are described that were designed to provide practice in phonetic transcription for students taking an introductory phonetics course. The goal was to allow instructors to offload much of the drill that would otherwise need to be covered in class or handled with paper-and-pencil tasks using text rather than speech as input. The exercises were developed using Alvin, a general-purpose software package for experiment design and control. The simplest exercises help students learn sound-symbol associations. For example, a vowel-transcription exercise presents listeners with consonant-vowel-consonant syllables on each trial; students are asked to choose among buttons labeled with phonetic symbols for 12 vowels. Several word-transcription exercises are included in which students hear a word and are asked to enter a phonetic transcription. Immediate feedback is provided for all of the exercises. An explanation of the methods that are used to create exercises is provided. Although no formal evaluation was conducted, comments on course evaluations suggest that most students found the exercises to be useful. Exercises were developed for use in an introductory phonetics course. The exercises can be used in their current form, they can be modified to suit individual needs, or new exercises can be developed.

Zeng, Nan; Pope, Zachary; Gao, Zan

2017-07-01

Commercially available virtual reality (VR) exercise systems are extensively used in many health domains among clinical populations. However, evidence regarding the efficacy of this technology on healthy adults' health-related outcomes is unknown. This pilot study compared physiological and psychological responses following exercise on a VR-based exercise bike (VirZoom) and traditional stationary exercise bike. Twelve healthy college students (9 females; M age  = 25.01, SD = ± 4.74; M BMI  = 22.84, SD = ± 3.68) completed two separate 20-minute exercise sessions on the VR-based exercise bike and traditional stationary exercise bike. Blood pressure (BP), ratings of perceived exertion, self-efficacy, and enjoyment were assessed as primary outcomes. Dependent t-tests indicated no significant differences in mean systolic or diastolic BP changes from pre to postexercise between the VR-based exercise and traditional stationary biking sessions (all p > 0.05). Notably, participants reported significantly higher ratings of perceived exertion (p < 0.05, Cohen's d = 0.68) during the traditional exercise biking session compared with VR-based exercise biking session. However, participants had significantly higher self-efficacy (p < 0.05, Cohen's d = -0.83) and enjoyment (p < 0.05, Cohen's d = -0.89) during the VR-based exercise biking session compared with traditional stationary biking. The commercially available VR-based exercise bike (VirZoom) may be considered an effective, enjoyable, and motivating physical activity tool. Further interventions with larger and more diverse samples and examinations of more health-related outcomes are warranted to determine optimal application of VR-based exercise programming among various populations.

2015-01-01

The purpose of this study was to determine the acute dose-response relationship of classroom exercise breaks with executive function and math performance in 9- to 12-year-old children by comparing 5-min, 10-min, or 20-min classroom exercise breaks to 10 min of sedentary classroom activity. This study used a within-subjects experimental design conducted in the spring of 2012. Ninety-six 4th- and 5th-grade students in 5 classrooms in South Carolina were randomized to receive each of 4 treatments: 5-min, 10-min, or 20-min exercise breaks or 10 min of a sedentary lesson led by research staff. Students completed the Trail-Making Test, an Operational Digit Recall test, and a math fluency test immediately before and after each condition. Planned linear contrasts were used to compare posttest scores between conditions using a repeated-measures mixed model, adjusted for gender, classroom, and the time-varying pretest scores. Potential effect modifiers were added as interaction terms. Math scores were higher after the 10-min and 20-min exercise breaks compared with the sedentary condition (d = 0.24, p = .04, and d = 0.27, p = .02, respectively), and an interaction was observed with gender, IQ, aerobic fitness, and lower engagement in some of the conditions. There were no improvements in executive function tasks. A 10-min and 20-min classroom exercise break moderately improved math performance in students compared with a seated classroom lesson.

Negative attitudes of physiotherapists may prevent them from implementing exercise as an intervention among people with disabilities. The aim of this study was to examine whether physiotherapy student attitudes towards the barriers to exercise for adolescents with Down syndrome changed as a result of participating in a 10-week exercise programme. Data were collected as part of a randomised controlled trial. Twenty physiotherapy students (2 men, 18 women; mean age 19.5±1.3 years) volunteered to act as mentors. Each mentor was matched with an adolescent with Down syndrome from the same metropolitan suburb, who had been randomly allocated to either the intervention or the control group. The 10 adolescents and students in the intervention group all completed a 10-week, twice a week progressive resistance exercise training programme. The 10 adolescents and students in the control group continued with their usual activities. The students completed the 18-item Exercise Barriers Scale at baseline and after 10 weeks. There was a positive change in attitudes, significant at the p <0.05 level, favouring the intervention group on 9 of the 18 items on the Exercise Barriers Scale. After engagement in a 10-week exercise programme with an adolescent with Down syndrome, physiotherapy students identified fewer barriers that would prevent adolescents with Down syndrome from exercising. Results indicate that contact with adolescents with Down syndrome during clinical placement can positively influence attitudes towards exercise for people with Down syndrome among physiotherapy students.

[Purpose] The aim was to investigate the effects of university students' smoking and aerobic exercise on metabolic syndrome risk factors. [Subjects and Methods] Twenty-three male students were randomly assigned to the following groups: exercise smoker (n=6), non-exercise smoker (n=6), exercise non-smoker (n=6), and non-exercise non-smoker (n=5). A basketball exercise program was conducted three times per week (70 minutes per session) for 8 weeks with exercise intensity set at 50-80% of heart rate reserve. After 8 weeks, the variables of risk factors for metabolic syndrome were obtained. [Results] Systolic blood pressure and diastolic blood pressure were significantly decreased in the exercise non-smoker group and significantly increased in the non-exercise smoker group. Waist circumference was significantly reduced in both exercise groups regardless of smoking and significantly increased in the non-exercise smoker group. Triglyceride, high-density lipoprotein-cholesterol, and fasting plasma glucose showed no differences between the groups. [Conclusion] Obesity and smoking management should be conducted together for students as well as for those with metabolic syndrome risk factors. It is recommended that more students participate in such programs, and exercise programs should be further developed and diversified to prevent metabolic syndrome and cardiovascular diseases.

Objective. To determine the impact of performing critical-thinking and reflection assignments within interdisciplinary learning teams in a biochemistry course on pharmacy students’ and prospective health professions students’ collaboration scores. Design. Pharmacy students and prospective medical, dental, and other health professions students enrolled in a sequence of 2 required biochemistry courses. They were randomly assigned to interdisciplinary learning teams in which they were required to complete case assignments, thinking and reflection exercises, and a team service-learning project. Assessment. Students were asked to complete the Scale of Attitudes Toward Physician-Pharmacist Collaboration prior to the first course, following the first course, and following the second course. The physician-pharmacist collaboration scores of prospective health professions students increased significantly (p<0.001). Conclusions. Having prospective health professions students work in teams with pharmacy students to think and reflect in and outside the classroom improves their attitudes toward physician-pharmacist collaboration.

Affordable hands-on DNA sequencing and genotyping: an exercise for teaching DNA analysis to undergraduates.

PubMed

Shah, Kushani; Thomas, Shelby; Stein, Arnold

2013-01-01

In this report, we describe a 5-week laboratory exercise for undergraduate biology and biochemistry students in which students learn to sequence DNA and to genotype their DNA for selected single nucleotide polymorphisms (SNPs). Students use miniaturized DNA sequencing gels that require approximately 8 min to run. The students perform G, A, T, C Sanger sequencing reactions. They prepare and run the gels, perform Southern blots (which require only 10 min), and detect sequencing ladders using a colorimetric detection system. Students enlarge their sequencing ladders from digital images of their small nylon membranes, and read the sequence manually. They compare their reads with the actual DNA sequence using BLAST2. After mastering the DNA sequencing system, students prepare their own DNA from a cheek swab, polymerase chain reaction-amplify a region of their DNA that encompasses a SNP of interest, and perform sequencing to determine their genotype at the SNP position. A family pedigree can also be constructed. The SNP chosen by the instructor was rs17822931, which is in the ABCC11 gene and is the determinant of human earwax type. Genotypes at the rs178229931 site vary in different ethnic populations. © 2013 by The International Union of Biochemistry and Molecular Biology.

2011-09-28

One of the toughest tasks in any profession is the deliverance of death notification. Marathon Death is an exercise conducted during the fourth year of medical school in northern Sweden to prepare students for this responsibility. The exercise is designed to enable students to gain insight into the emotional and formal procedure of delivering death notifications. The exercise is inspired by Augusto Boal's work around Forum Theatre and is analyzed using video playback. The aim of the study was to explore reflections, attitudes and ideas toward training in delivering death notifications among medical students who participate in the Marathon Death exercise based on forum play. After participation in the Marathon Death exercise, students completed semi-structured interviews. The transcribed interviews were analyzed using the principles of qualitative content analysis including a deductive content analysis approach with a structured matrix based on Bloom's taxonomy domains. The Marathon Death exercise was perceived as emotionally loaded, realistic and valuable for the future professional role as a physician. The deliverance of a death notification to the next of kin that a loved one has died was perceived as difficult. The exercise conjured emotions such as positive expectations and sheer anxiety. Students perceived participation in the exercise as an important learning experience, discovering that they had the capacity to manage such a difficult situation. The feedback from the video playback of the exercise and the feedback from fellow students and teachers enhanced the learning experience. The exercise, Marathon Death, based on forum play with video playback is a useful pedagogical tool that enables students to practice delivering death notification. The ability to practice under realistic conditions contributes to reinforce students in preparation for their future professional role.

Grounded in self-determination theory and trans-theoretical model applied to exercise, the aim of this study was to analyse the existing relationships between physical activity (PA) carried out by university students, perceived barriers to PA, motivation to PA and stages of change. 901 Spanish students took part in the study (408 men, 493 women; mean age 22.59±3.59), who completed the Behavioural Regulation in Exercise Questionnaire (BREQ-3), Scale of Barriers to PA, Stages of Change and the International Physical Activity Questionnaire - Short Form (IPAQ-SF). Noteworthy among the findings is the positive relationship between the more autonomous regulation forms, especially integrated regulation, and the moderate to vigorous PA (MVPA) levels. However, barriers to participatrion are negatively related to PA levels and the more self-determined forms of motivation. Finally, students in action and maintenance stages, and those who comply with the recommendations on PA present higher values in the more self-determined motivation forms and lower values in barriers to participation in PA. The study shows the importance of addressing the analysis of variables associated with engagement in PA in the university population to develop healthy policies and intervention programmes that can establish a series of healthy and more active habits in the youth-adult stage. The appropriateness of promoting more self-determined motivation forms is highlighted, especially integrated regulation, to have an impact on higher levels of MVPA.

Student performance in computing education: an empirical analysis of online learning in programming education environments

2017-11-01

The benefits of using online exercises have been analysed in terms of distance learning, automatic assessment and self-regulated learning. In this study, we have not found a direct proportional relationship between student performance in the course exercises that use online technologies and the exam grades. We see that the average submission rate to these online exercises is not positively correlated with the exercise points. Yet, our results confirm that doing exercises along supports student learning and skill accumulation equipping them with the knowledge of programming. While the student performance in programming courses is affected by factors such as prior background in programming, cognitive skills and the quality of teaching, completing the course exercises via learning-by-doing is an indispensable part of teaching. Based on the student feedback from the course survey, the students are highly satisfied with using online technologies as part of learning.

Climate-Literacy Laboratory Exercises for Undergraduate Students in an Introductory Weather and Climate Course

NASA Astrophysics Data System (ADS)

Diem, J.; Elliott, W.; Criswell, B.; Morrow, C. A.

2012-12-01

A suite of NASA-sponsored, Web-based exercises are in development for an introductory weather and climate course at Georgia State University (GSU) to improve climate literacy among undergraduate students. An extremely small percentage of the students are STEM majors. The exercises make extensive use of NASA resources and are guided in part by the concepts in Climate Literacy: The Essential Principles of Climate Science. At least two thousand undergraduate students have completed a majority of the exercises over the past two years. Nine of the twelve exercises in the course are connected strongly to climate literacy. The topics of those nine exercises are as follows: (1) Solar Irradiance, (2) Stratospheric Ozone, (3) Tropospheric Air, (4) The Carbon Cycle, (5) Global Surface Temperature, (6) Glacial-Interglacial Cycles, (7) Temperature Changes during the Past Millennium, (8) Climate & Ecosystems, and (9) Current & Future Climate Change. Two of the exercises (Tropospheric Air and The Carbon Cycle) make use of carbon dioxide (CO2) measurements made by students themselves and by a stationary CO2 monitor at GSU. The three remaining exercises, The Hadley Cell, Atlanta Weather, and Air Pollution, are less connected to multiple climate-literacy concepts; nonetheless, they provide a more complete experience for the students in the understanding of climate processes, differences between weather and climate, and human impacts on the atmosphere. All exercises are based on an inquiry-based learning cycle (i.e. 7 Es) and require substantial amounts of engagement, applied thinking, and critical thinking by the students. Not only do students become knowledgeable about the essential principles of climate change, especially global warming, but extensive use of geographical-information software and hand-held measurement devices has provided students with training in geography and technology. Student attitudes towards the labs were gathered via an on-line, anonymous survey from hundreds of students in Geography 1112 during the Fall semester of 2010. Students liked the use of high-quality imagery and animations, using Google™ earth, using Microsoft® Excel for calculations and chart production, going outside to collect data, and working in groups. Students did not like the large number of questions in some of the labs, not receiving a "lecture" in the beginning lab exercise, and improperly working Web links. Students suggested having a small lecture at the beginning in addition to having the topics be presented in the lecture sessions before doing the lab exercises as way to improve the labs. Therefore, students desired a more traditional approach to instruction. Seven lab instructors, all of whom were graduate students in the Department of Geosciences, were interviewed by the project evaluator in April of 2011. The main findings were as follows: the instructors viewed themselves as facilitators of the student-centered exercises; the students are uncomfortable with an inquiry-based approach; and there is disconnection between the lecture and lab portions of the course. Future work involves major pedagogical renovations to the exercises, training the lab instructors in the leading of inquiry-based exercises, and assessing student learning of climate-change concepts using pre- and post-tests.

OBJECTIVE. To determine whether a high-fidelity simulation technique compared with lecture would produce greater improvement in advanced cardiac life support (ACLS) knowledge, confidence, and overall satisfaction with the training method. DESIGN. This sequential, parallel-group, crossover trial randomized students into 2 groups distinguished by the sequence of teaching technique delivered for ACLS instruction (ie, classroom lecture vs high-fidelity simulation exercise). ASSESSMENT. Test scores on a written examination administered at baseline and after each teaching technique improved significantly from baseline in all groups but were highest when lecture was followed by simulation. Simulation was associated with a greater degree of overall student satisfaction compared with lecture. Participation in a simulation exercise did not improve pharmacy students' knowledge of ACLS more than attending a lecture, but it was associated with improved student confidence in skills and satisfaction with learning and application. CONCLUSIONS. College curricula should incorporate simulation to complement but not replace lecture for ACLS education.

Teaching concepts of clinical measurement variation to medical students.

PubMed

Hodder, R A; Longfield, J N; Cruess, D F; Horton, J A

1982-09-01

An exercise in clinical epidemiology was developed for medical students to demonstrate the process and limitations of scientific measurement using models that simulate common clinical experiences. All scales of measurement (nominal, ordinal and interval) were used to illustrate concepts of intra- and interobserver variation, systematic error, recording error, and procedural error. In a laboratory, students a) determined blood pressures on six videotaped subjects, b) graded sugar content of unknown solutions from 0 to 4+ using Clinitest tablets, c) measured papules that simulated PPD reactions, d) measured heart and kidney size on X-rays and, e) described a model skin lesion (melanoma). Traditionally, measurement variation is taught in biostatistics or epidemiology courses using previously collected data. Use of these models enables students to produce their own data using measurements commonly employed by the clinician. The exercise provided material for a meaningful discussion of the implications of measurement error in clinical decision-making.

Characterizing Mystery Cell Lines: Student-driven Research Projects in an Undergraduate Neuroscience Laboratory Course.

Lemons, Michele L

2012-01-01

Inquiry-based projects promote discovery and retention of key concepts, increase student engagement, and stimulate interest in research. Described here are a series of lab exercises within an undergraduate upper level neuroscience course that train students to design, execute and analyze their own hypothesis-driven research project. Prior to developing their own projects, students learn several research techniques including aseptic cell culture, cell line maintenance, immunocytochemistry and fluorescent microscopy. Working in groups, students choose how to use these techniques to characterize and identify a "mystery" cell line. Each lab group is given a unique cell line with either a neural, astrocyte, or Schwann cell origin. Working together, students plan and execute experiments to determine the cellular origin and other unique characteristics of their mystery cell line. Students generate testable hypotheses, design interpretable experiments, generate and analyze data, and report their findings in both oral and written formats. Students receive instructor and peer feedback throughout the entire project. In summary, these labs train students the process of scientific research. This series of lab exercises received very strong positive feedback from the students. Reflections on student feedback and plans for future improvements are discussed.

Delegation, an important concept for nursing students to learn and practice, is central to registered nurse (RN) performance, and important on the NCLEX-RN examination. Nursing faculty members from an ADN program designed a descriptive study to evaluate planned versus actual delegation in the curriculum, and a second study to evaluate an intervention on delegation. Study One assessed the presence of delegation in each nursing course. Statistical analysis compared the planned implementation with the results for student definitions of delegation, and identification of the five rights of delegation based on the National Council of State Boards of Nursing (NCSBN) definition and five rights. Study one results are shared. Study Two utilized a comparison of pre-to-post intervention measures. Students were asked to complete eight steps of a delegation exercise and determine what could be delegated to an unlicensed assistant, and what should be completed by the RN. Answers were coded and entered into SPSS. Statistical analysis compared each student's ability to correctly identify the five rights of delegation prior to the exercise, against the ability to correctly answer five questions two weeks post exercise. Significant improvement (p< 0.05) occurred on each measure. Recommendations are discussed.

Predictors of obesity bias among exercise science students.

PubMed

Langdon, Jody; Rukavina, Paul; Greenleaf, Christy

2016-06-01

The purpose of the present study was to investigate particular psychosocial predictors of obesity bias in prehealth professionals, which include the internalization of athletic and general body ideals, perceived media pressure and information, and achievement goal orientations. Exercise science undergraduate students (n= 242) filled out a survey containing questions of demographic characteristics, achievement goals, social-cultural attitudes toward appearance (using Sociocultural Attitudes Towards Appearance Questionnaire-3), and obesity bias measurements (using the antifat attitudes test and fat phobia scale). The results indicated that students were explicitly biased toward overweight and obese individuals, held had high task and ego goals, and had high internalization of an athletic body type ideal, as determined by mean scores being above the median values for each scale. Internalization of the athletic body type predicted obesity bias for fat phobia, weight control blame, and physical/romantic attractiveness. In conclusion, exercise science students may enter programs socialized from society and sport, and, potentially, these psychosocial attitudes and beliefs may have implications to working with future clients, especially for those of the general population and those whose body shape and size are different than themselves.

University students are vulnerable to poor nutrition; they don't eat snacks between meals, don't eat breakfast or fast for long hours, prefer fast food and don't exercise. University students is considered the key young adult population group for health promotion and prevention for future generations, so it's crucial identify the current nutritional status and frequency of physical activity. To determine the factors involved in the choice of food and frequency of physical activity in university students. 799 volunteers were evaluated from four universities of the fifth region of Chile. Instrument was applied to determine the level of physical activity and eating habits, KIDMED test to determine adherence to the Mediterranean diet and Adimark instrument to determinate the socioeconomic status of the subjects. Finally, anthropometric evaluation to determinate BMI, fat mass and muscle mass. Physical inactivity is higher in women than in men and that the main reason for not exercising is lack of time and laziness. In both sexes don't read nutrition labels and have a low and average adherence to the Mediterranean diet. The low knowledge of nutrition is the cause of the poor food quality of subjects and there isn't greater motivation to perform physical activity.Socioeconomic status isn't related to eating habits and physical activity. It's necessary to integrate programs regular and permanent healthy lifestyle in all universities. Copyright © AULA MEDICA EDICIONES 2013. Published by AULA MEDICA. All rights reserved.

This article aimed to evaluate the effectiveness of newly established innovative smart home healthcare and health informatics laboratories, and a novel laboratory course that focuses on experiential health informatics training, and determine students' self-confidence to operate wireless home health monitoring devices before and after the hands-on laboratory course. Two web-based pretraining and posttraining questionnaires were sent to 64 students who received hands-on training with wireless remote patient monitoring devices in smart home healthcare and health informatics laboratories. All 64 students completed the pretraining survey (100% response rate), and 49 students completed the posttraining survey (76% response rate). The quantitative data analysis showed that 95% of students had an interest in taking more hands-on laboratory courses. Sixty-seven percent of students had no prior experience with medical image, physiological data acquisition, storage, and transmission protocols. After the hands-on training session, 75.51% of students expressed improved confidence about training patients to measure blood pressure monitor using wireless devices. Ninety percent of students preferred to use a similar experiential approach in their future learning experience. Additionally, the qualitative data analysis demonstrated that students were expecting to have more courses with hands-on exercises and integration of technology-enabled delivery and patient monitoring concepts into the curriculum. This study demonstrated that the multidisciplinary smart home healthcare and health informatics training laboratories and the hands-on exercises improved students' technology adoption rates and their self-confidence in using wireless patient monitoring devices.

2012-06-01

Exercise is endorsed for its physiological and psychological benefits, and has been proposed to have positive effects on impression formation. To test this proposal, 62 female and 44 male college students read one of three brief descriptions of either a fictitious male or female "target" student. The descriptions varied only in exercise level: no exercise; moderate exercise and intensive exercise. Participants then rated the fictitious student on 38 personality traits. Ratings of characteristics that are associated with exercise (e.g. athletic; energetic) increased, while ratings associated with the lack of exercise (e.g. lazy; weak) decreased as a function of the reported level of exercise. Exercise level also positively influenced ratings of characteristics not related to exercise. These data show that even minimal information about exercise is an important component of first impressions in both men and women. Copyright © 2012 Elsevier Ltd. All rights reserved.

2008-12-01

Lithologic data from 40 DSDP, ODP, and IODP scientific ocean drilling cores from the Pacific and North Atlantic oceans are the basis for an inquiry-based classroom exercise module for college introductory geology and oceanography courses. Part 1 of this exercise module is designed as an initial inquiry aimed at drawing out student beliefs and prior knowledge. In Parts 2-3 students observe and describe the physical characteristics of sediment cores using digital core photos, and determine the sediment composition using smear slide data and a decision tree. In Part 4 students combine their individual site data to construct a map showing the distribution of the primary marine sediment types of the Pacific and North Atlantic Oceans, and develop hypotheses to explain the distribution of the sediment types shown on their map. The transportable skills of observation, forming questions, plotting data, interpreting data, and scientific synthesis are embedded in this module, benefitting non-majors as well as majors. The exercise module was tested in the 2008 School of Rock program and the 2008 Urbino Summer School for Paleoceanography, and is currently being tested in undergraduate courses at James Madison University, North Hennipen Community College, St. Cloud State University and University of Massachusetts, Amherst in classes that range in size from 16 students to >150 students. The student worksheets, instructor guide, and preliminary evaluation data will be presented.

We describe a structured inquiry laboratory exercise that examines transcriptional regulation of the NOS2 gene under conditions that simulate the inflammatory response in macrophages. Using quantitative PCR and the comparative CT method, students are able determine whether transcriptional activation of NOS2 occurs and to what degree. The exercise is aimed at second year undergraduates who possess basic knowledge of gene expression events. It requires only 4-5 hr of dedicated laboratory time and focuses on use of the primary literature, data analysis, and interpretation. Importantly, this exercise provides a mechanism to introduce the concept of differential gene expression and provides a starting point for development of more complex guided or open inquiry projects for students moving into upper level molecular biology, immunology, and biochemistry course work. © 2015 The International Union of Biochemistry and Molecular Biology.

Exercise and diet determinants of overweight women participating in an exercise and diet program: a prospective examination of the theory of planned behavior.

PubMed

Gardner, Rebecca Ellis; Hausenblas, Heather A

2005-01-01

The purpose of this study was to examine prospectively the ability of direct and belief-based measures of the theory of planned behavior (TPB) constructs to predict exercise and diet intention and behavior of overweight women. Participants were 117 overweight, community-dwelling women and university students enrolled in a 4-week exercise and diet program. Participants completed baseline measures of demographic characteristics and the TPB constructs. Their exercise and diet adherence were also recorded. We found that: (1) the direct measure of perceived behavioral control (PBC) predicted exercise intention, (2) the direct measures of instrumental attitude, subjective norm, and PBC predicted diet intention, and (3) none of the direct or belief-based measures of the TPB constructs predicted 4-week exercise or diet behavior. Furthermore, several beliefs were associated with the direct measures of attitude, subjective norm, PBC, and intention. Implications of these results for designing exercise and diet interventions with overweight women are discussed.

Physical Education Students' Ownership, Empowerment, and Satisfaction With PE and Physical Activity.

PubMed

Moore, E Whitney G; Fry, Mary D

2017-12-01

Individuals experiencing a highly caring, task-involving, and low ego-involving exercise climate have reported greater ownership in exercise class and empowerment to exercise in general. This study examined the relationship between ownership and empowerment in exercise, with 2 context-specific outcomes, satisfaction with physical education (PE) and physical activity, respectively. Given the mission of PE to foster individuals' lifelong physical activity habit, the perceptions of high school students were collected for this study. Ownership in exercise was hypothesized to be significantly, positively correlated with students reporting satisfaction in PE more than their satisfaction in physical activity, whereas empowerment in exercise was hypothesized to be more strongly, positively correlated with students' physical activity satisfaction. A second purpose of this study was to test the measurement quality of the updated Empowerment in Exercise Scale (EES; now 13 items). High school students (N = 502, 43% female) in a Midwestern U.S. school district completed a survey. Confirmatory factor analysis supported the internal measurement structure of the EES (λ = .62-.91; McDonald's omega = .89) across student gender (strong invariance). Additionally, the structural equation modeling analysis revealed only 1 parameter moderated by the students' gender (latent mean of ownership). The hypotheses were supported, such that ownership in exercise was more strongly correlated with PE satisfaction (r = .87) and empowerment in exercise had a stronger correlation with physical activity satisfaction (r = .92). These results support the beneficial effect a satisfying experience in PE can have on students' satisfaction with physical activity outside of school.

Harrold, Marc W; McFalls, Marsha A

2010-10-11

To develop exercises that allow pharmacy students to apply foundational knowledge discussed in a first-professional year (P1) biochemistry course to specific disease states and patient scenarios. A pharmacy practice laboratory exercise was developed to accompany a lecture sequence pertaining to purine biosynthesis and degradation. The assignment required students to fill a prescription, provide patient counseling tips, and answer questions pertaining to the disease state, the underlying biochemical problem, and the prescribed medication. Students were graded on the accuracy with which they filled the prescription, provided patient counseling, and answered the questions provided. Overall, students displayed mastery in all of these areas. Additionally, students completed a course survey on which they rated this exercise favorably, noting that it helped them to integrate basic science concepts and pharmacy practice. A laboratory exercise provided an opportunity for P1 students to apply foundational pharmacy knowledge to a patient case and can serve as a template for the design of additional exercises.

Laboratory exercises to teach clinically relevant chemistry of antibiotics.

PubMed

El Sayed, Khalid A; Chelette, Candace T

2014-03-12

To design, implement, and evaluate student performance on clinically relevant chemical and spectral laboratory exercises on antibiotics. In the first of 2 exercises, second-year pharmacy students enrolled in an integrated laboratory sequence course studied the aqueous stability of ß-lactam antibiotics using a spectral visual approach. In a second exercise, students studied the tendency of tetracycline, rifamycins, and fluoroquinolones to form insoluble chelate complexes (turbidity) with polyvalent metals. On a survey to assess achievement of class learning objectives, students agreed the laboratory activities helped them better retain important information concerning antibiotic stability and interactions. A significant improvement was observed in performance on examination questions related to the laboratory topics for 2012 and 2013 students compared to 2011 students who did not complete the laboratory. A 1-year follow-up examination question administered in a separate course showed >75% of the students were able to identify rifamycins-food interactions compared with <25% of students who had not completed the laboratory exercises. The use of spectral visual approaches allowed students to investigate antibiotic stability and interactions, thus reinforcing the clinical relevance of medicinal chemistry. Students' performance on questions at the 1-year follow-up suggested increased retention of the concepts learned as a result of completing the exercises.

This paper aims to investigate the methods and sample used in rope skipping as an exercise approach. A systematic literature review was approached in identifying skipping performance in the related researches. The methods were compared to determine the best methodological approach for the targeted skipping based research measure. A pilot test was performed among seven students below 12 years old. As the outcome of the review, a skipping protocol design has been proposed for 10 years old primary school students. The proposed protocol design is to be submitted to PPUKM Ethical Committee for approval prior to its implementation in investigation memory enhancement in relation to designed skipping activities.

Running to well-being: A comparative study on the impact of exercise on the physical and mental health of law and psychology students.

PubMed

Skead, Natalie K; Rogers, Shane L

Research indicates that, in comparison to other university students, law students are at greater risk of experiencing high levels of psychological distress. There is also a large body of literature supporting a general negative association between exercise and stress, anxiety and depression. However, we are not aware of any studies exploring the impact of exercise on the mental health of law students specifically. This article reports evidence of a negative association between exercise and psychological distress in 206 law and psychology students. Compared to psychology students, the law students not only reported greater psychological distress, but, in addition, there was a stronger association between their levels of distress and their levels of exercise. Based on the results of this study, we suggest a simple yet effective way law schools might support the mental health of their students. Copyright © 2016 Elsevier Ltd. All rights reserved.

Predicting students' physical activity and health-related well-being: a prospective cross-domain investigation of motivation across school physical education and exercise settings.

Standage, Martyn; Gillison, Fiona B; Ntoumanis, Nikos; Treasure, Darren C

2012-02-01

A three-wave prospective design was used to assess a model of motivation guided by self-determination theory (Ryan & Deci, 2008) spanning the contexts of school physical education (PE) and exercise. The outcome variables examined were health-related quality of life (HRQoL), physical self-concept (PSC), and 4 days of objectively assessed estimates of activity. Secondary school students (n = 494) completed questionnaires at three separate time points and were familiarized with how to use a sealed pedometer. Results of structural equation modeling supported a model in which perceptions of autonomy support from a PE teacher positively predicted PE-related need satisfaction (autonomy, competence, and relatedness). Competence predicted PSC, whereas relatedness predicted HRQoL. Autonomy and competence positively predicted autonomous motivation toward PE, which in turn positively predicted autonomous motivation toward exercise (i.e., 4-day pedometer step count). Autonomous motivation toward exercise positively predicted step count, HRQoL, and PSC. Results of multisample structural equation modeling supported gender invariance. Suggestions for future work are discussed.

The impact of incentives on intrinsic and extrinsic motives for fitness-center attendance in college first-year students.

2015-01-01

A criticism of incentives for health behaviors is that incentives undermine intrinsic motivation. The objective of this study was to determine the impact of monetary incentive provision on participation motives for exercise in first-year college students at a northeastern public university. Randomized-controlled trial. Public university in the Northeastern United States. One hundred seventeen first-year college students. Participants were randomized to one of three conditions: a control condition receiving no incentives for meeting fitness-center attendance goals; a discontinued-incentive condition receiving weekly incentives during fall semester 2011, and no incentives during spring semester 2012; or a continued-incentive condition receiving weekly incentives during fall semester, and incentives on a variable-interval schedule during spring semester. The Exercise Motivation Inventory 2 measured exercise participation motives at baseline, end of fall semester, and end of spring semester. Fitness-center attendance was monitored by using ID-card check-in/check-out records. Repeated-measures analyses using linear mixed models with first-order autoregressive covariance structures were run to compare motive changes in the three conditions. Participation motives of Enjoyment and Revitalization associated with intrinsic motivation did not decrease significantly over time in any of the conditions, F(4, 218) = 2.25, p = .065 and F(4, 220) = 1.67, p = .16, respectively. Intrinsically associated participation motives for exercise did not decrease with incentive provision. Therefore, incentives may encourage fitness-center attendance without negatively impacting participation motives for exercise.

Health status, physical activity, and orthorexia nervosa: A comparison between exercise science students and business students.

2017-02-01

Orthorexia nervosa is described as an exaggerated fixation on healthy food. It is unclear whether students in health-oriented academic programs, highly focused on physical exercise, are more prone to develop orthorexia nervosa than students in other educational areas. The aim was to compare health status, physical activity, and frequency of orthorexia nervosa between university students enrolled in an exercise science program (n = 118) or a business program (n = 89). The students completed the Short Form-36 Health Survey (SF-36), the International Physical Activity Questionnaire (IPAQ), and ORTO-15, which defines orthorexia nervosa as a sensitive and obsessive behavior towards healthy nutrition. The SF-36 showed that exercise science students scored worse than business students regarding bodily pain (72.8 vs. 82.5; p = 0.001), but better regarding general health (83.1 vs. 77.1; p = 0.006). Of 188 students, 144 (76.6%) had an ORTO-15 score indicating orthorexia nervosa, with a higher proportion in exercise science students than in business students (84.5% vs. 65.4%; p = 0.002). Orthorexia nervosa in combination with a high level of physical activity was most often seen in men in exercise science studies and less often in women in business studies (45.1% vs. 8.3%; p < 0.000). A high degree of self-reporting of pain and orthorexia nervosa in exercise science students may cause problems in the future, since they are expected to coach others in healthy living. Our findings may be valuable in the development of health-oriented academic programs and within student healthcare services. Copyright © 2016 Elsevier Ltd. All rights reserved.

Can an Inquiry Approach Improve College Student Learning in a Teaching Laboratory?

PubMed Central

Cogan, John G.

2009-01-01

We present an inquiry-based, hands-on laboratory exercise on enzyme activity for an introductory college biology course for science majors. We measure student performance on a series of objective and subjective questions before and after completion of this exercise; we also measure performance of a similar cohort of students before and after completion of an existing, standard, “direct” exercise over the same topics. Although student performance on these questions increased significantly after completion of the inquiry exercise, it did not increase after completion of the control, standard exercise. Pressure to “cover” many complex topics as preparation for high-stakes examinations such as the Medical College Admissions Test may account for persistence of highly efficient, yet dubiously effective “cookbook” laboratory exercises in many science classes.

Active-learning diabetes simulation in an advanced pharmacy practice experience to develop patient empathy.

PubMed

Whitley, Heather P

2012-12-12

To develop and integrate an active-learning diabetes simulation into an advanced pharmacy practice experience to improve pharmacy students' empathy toward patients with diabetes mellitus. Students simulated the experience of having diabetes mellitus by conducting activities commonly prescribed to those with this disease state for 7 days, after which they submitted a standardized diabetes log and narrative reflection. Interpretive phenomenology design with thematic analysis was used to determine the impact of this experience on the students. As shown in student reflections, 95% developed empathy, 97% found the experience beneficial, and 67% improved their ability to relate to and counsel patients. Most (95%) found difficulty adhering to the regimen. On average, students consumed 179 grams of carbohydrates per day and exercised 5 days or 215 minutes per week. Additionally, 69% decided to modify their personal habits to become healthier. Inclusion of the 7-day active-learning exercise greatly impacted student pharmacists' self-reported empathy toward and ability to relate to patients with diabetes mellitus. Completion of this experience may result in long-lasting personal behavior modifications.

Gerber, Markus; Brand, Serge; Elliot, Catherine; Holsboer-Trachsler, Edith; Pühse, Uwe

2014-12-01

This exploratory study was designed to compare four types of exercise activities in Swiss university students. A sample of 201 medical students (136 women, 65 men; M age = 23.2 yr., SD = 2.4) and 250 exercise and health sciences students (144 women, 106 men; M age = 22.3 yr., SD = 2.2) participated in the study. They completed the Perceived Stress Scale, the Depression Scale, and the Office in Motion Questionnaire. Interaction effects between stress and exercise activities were analysed using hierarchical regression analyses, after controlling for age, sex, and academic discipline. Frequent participation in ball sports and dancing were associated with decreased depressive symptoms among students with elevated perceived stress, whereas no such relationship existed among their peers with lower perceived stress. No stress-moderating effect was found for aerobic exercise. Weight lifting was only associated with lower depressive symptoms among students with low perceived stress. The present findings suggest that, among Swiss university students, certain exercises may have better potential to moderate the relationship between perceived stress and depressive symptoms than others. Future research could analyze whether personalized exercise programs created to satisfy participants' individual needs are more beneficial for stress management.

Laboratory Exercises to Teach Clinically Relevant Chemistry of Antibiotics

PubMed Central

Chelette, Candace T.

2014-01-01

Objectives. To design, implement, and evaluate student performance on clinically relevant chemical and spectral laboratory exercises on antibiotics. Design. In the first of 2 exercises, second-year pharmacy students enrolled in an integrated laboratory sequence course studied the aqueous stability of ß-lactam antibiotics using a spectral visual approach. In a second exercise, students studied the tendency of tetracycline, rifamycins, and fluoroquinolones to form insoluble chelate complexes (turbidity) with polyvalent metals. Assessment. On a survey to assess achievement of class learning objectives, students agreed the laboratory activities helped them better retain important information concerning antibiotic stability and interactions. A significant improvement was observed in performance on examination questions related to the laboratory topics for 2012 and 2013 students compared to 2011 students who did not complete the laboratory. A 1-year follow-up examination question administered in a separate course showed >75% of the students were able to identify rifamycins-food interactions compared with <25% of students who had not completed the laboratory exercises. Conclusion. The use of spectral visual approaches allowed students to investigate antibiotic stability and interactions, thus reinforcing the clinical relevance of medicinal chemistry. Students’ performance on questions at the 1-year follow-up suggested increased retention of the concepts learned as a result of completing the exercises. PMID:24672070

2014-01-01

The purpose of the current study was to examine the association between the level of exercise behavior and individual and environmental factors related to exercise behavior among female Japanese undergraduate students. The participants were 2482 female Japanese undergraduate students. Participants' level of exercise behavior was measured by the stage of change to exercise in the transtheoretical model. Individual and environmental factors related to exercise behavior were assessed using body mass index, self-efficacy, social support, perceived positive and negative aspects of exercise, perceived neighborhood environment, attitude toward physical education lessons in childhood and puberty, and depression. Scores for self-efficacy, social support, positive aspects of exercise, and perceived neighborhood environment were significantly higher among women who were more active compared with those who were inactive. On the other hand, scores for negative aspects of exercise and depression were greater among inactive women compared with those who were insufficiently active and/or active. In addition, past attitude toward exercise in primary school, junior high school, and high school was associated with current level of exercise behavior. This cross-sectional study confirmed that psychosocial and environmental factors were closely associated with level of exercise behavior among female Japanese undergraduate students.

Objective. To analyze student perceptions of self-efficacy in meeting medicinal chemistry course related educational outcomes and skills following a medicinal chemistry skills laboratory. Methods. Four activities were implemented in a pharmacy skills laboratory (PSL) for second-year pharmacy students. Students (n=121) worked individually on exercises for three of the four activities. Pre/post-laboratory surveys on self-efficacy were administered. The McNemar test was performed to evaluate students' self-efficacy above 70% related to course outcomes before and after the exercises in each activity. An independent t test was conducted to compare the mean of students' responses on meeting course outcomes based on the 70% anchor for the perspective confidence on meeting course outcomes. Results. The post-PSL scores on all self-efficacy questions improved. The majority of students reported skill development in all exercises. Students and clinical faculty qualitative responses indicated they felt exercises were effective. Conclusion. A PSL can serve as a valuable opportunity to address course related educational outcomes and specific skill development and can help students assess their self-efficacy in meeting them.

Promoting Inquiry-Based Teaching in Laboratory Courses: Are We Meeting the Grade?

PubMed Central

Butler, Amy; Burke da Silva, Karen

2014-01-01

Over the past decade, repeated calls have been made to incorporate more active teaching and learning in undergraduate biology courses. The emphasis on inquiry-based teaching is especially important in laboratory courses, as these are the courses in which students are applying the process of science. To determine the current state of research on inquiry-based teaching in undergraduate biology laboratory courses, we reviewed the recent published literature on inquiry-based exercises. The majority of studies in our data set were in the subdisciplines of biochemistry, cell biology, developmental biology, genetics, and molecular biology. In addition, most exercises were guided inquiry, rather than open ended or research based. Almost 75% of the studies included assessment data, with two-thirds of these studies including multiple types of assessment data. However, few exercises were assessed in multiple courses or at multiple institutions. Furthermore, assessments were rarely based on published instruments. Although the results of the studies in our data set show a positive effect of inquiry-based teaching in biology laboratory courses on student learning gains, research that uses the same instrument across a range of courses and institutions is needed to determine whether these results can be generalized.

Brown, Stacy D

2010-09-10

To integrate process-oriented guided-inquiry learning (POGIL) team-based activities into a 1-semester medicinal chemistry course for doctor of pharmacy (PharmD) students and determine the outcomes. Students in the fall 2007 section of the Medicinal Chemistry course were taught in a traditional teacher-centered manner, with the majority of class time spent on lectures and a few practice question sets. Students in the fall 2008 and fall 2009 sections of Medicinal Chemistry spent approximately 40% of class time in structured self-selected teams where they worked through guided-inquiry exercises to supplement the lecture material. The mean examination score of students in the guided-inquiry sections (fall 2008 and fall 2009) was almost 3 percentage points higher than that of students in the fall 2007 class (P < 0.05). Furthermore, the grade distribution shifted from a B-C centered distribution (fall 2007 class) to an A-B centered distribution (fall 2008 and fall 2009 classes). The inclusion of the POGIL style team-based learning exercises improved grade outcomes for the students, encouraged active engagement with the material during class time, provided immediate feedback to the instructor regarding student-knowledge deficiencies, and created a classroom environment that was well received by students.

Purpose Medical students are expected to develop excellent communication skills. The purpose of our study was to create an innovative communication skills exercise using real volunteer patients and physician co-teachers for students to practice communication skills while receiving immediate feedback. Method This is a mixed methods study where second-year medical students participated in the communication skills exercise with real patients and physician co-teachers giving immediate feedback. Clinical scenarios reflected the patients’ actual experiences. Students acted out roles as physicians. Physicians co-taught with the patients and gave immediate feedback to students. Students completed an anonymous written survey at the end of the exercise. Qualitative and quantitative responses were recorded. Student feedback from the 2014 surveys was used to modify the teaching designs to increase active role play opportunities by having only two students in each group and doubling the number of stations with real patients. Results Students rated the overall exercise and the utility of patient volunteers in learning how to communicate on a Likert scale of 1–5, where in this medical school traditionally 1 is excellent and 5 is poor. In 2014, the exercises were rated with a mean score of 1.47 (SD 0.621). In 2015, the exercises were rated with a mean score of 1.03 (SD 0.62). In 2016, the exercises were rated with a mean score of 1.27 (SD 0.52). ANOVA analysis (p=0.002) and Bonferroni corrections indicate a statistically significant difference between combined mean scores of the exercise in 2014 and 2015 (p=0.001). No difference was shown between 2014 and 2016 or 2015 and 2016. Conclusions Medical students rated practicing communication skills with real patient volunteers and physician co-teachers giving immediate feedback in their preclinical years very highly. Student feedback indicated that they preferred active roles and increased opportunities to practice their communication skills. PMID:28579871

Researchers have examined the physical activity (PA) habits of certified athletic trainers; however, none have looked specifically at athletic training students. To assess PA participation and constraints to participation among athletic training students. Cross-sectional study. Entry-level athletic training education programs (undergraduate and graduate) across the United States. Participants were 1125 entry-level athletic training students. Self-reported PA participation, including a calculated PA index based on a typical week. Leisure constraints and demographic data were also collected. Only 22.8% (252/1105) of athletic training students were meeting the American College of Sports Medicine recommendations for PA through moderate-intensity cardiorespiratory exercise. Although 52.3% (580/1105) were meeting the recommendations through vigorous-intensity cardiorespiratory exercise, 60.5% (681/1125) were meeting the recommendations based on the combined total of moderate or vigorous cardiorespiratory exercise. In addition, 57.2% (643/1125) of respondents met the recommendations for resistance exercise. Exercise habits of athletic training students appear to be better than the national average and similar to those of practicing athletic trainers. Students reported structural constraints such as lack of time due to work or studies as the most significant barrier to exercise participation. Athletic training students experienced similar constraints to PA participation as practicing athletic trainers, and these constraints appeared to influence their exercise participation during their entry-level education. Athletic training students may benefit from a greater emphasis on work-life balance during their entry-level education to promote better health and fitness habits.

2011-01-01

Clinical clerkship directors and faculty undertake the challenge of teaching patient-centered communication to students who face the enormous doctor-centered task of learning diagnostic medicine. The authors examined students' written reactions to the narrative exercise, which, drawing from narrative medicine and narrative therapy, challenges students to be more patient-centered by writing a patient's life story and sharing it with that patient. During one-half of an academic year (2008-2009), the authors used qualitative methods to explore the range of medical student experiences with the narrative exercise in the psychiatry clerkship. During the study period, 46 medical students completed the exercise, and 44 (96%) submitted 367 comments for the research team to analyze. Four broad categories emerged: (1) communication, (2) insight, (3) hope, and (4) mixed or negative reactions. The most common theme was improved communication, which comprised the subcategories of enhanced active listening, opening up, and relationship building. Improved insights included student insights into their patients, as well as the facilitation of patient insights into themselves, especially regarding their own strengths and relationships. The exercise was well received by students: Only five comments were categorized as negative, and all of these related to difficulties selecting patients. Students reported many examples of improved patient-centered communication facilitated by the exercise. The narrative exercise may also promote a greater understanding of patients as complete human beings rather than diagnostic entities. The approach may be useful in educational settings beyond the psychiatry clerkship.

"I just feel so guilty": The role of introjected regulation in linking appearance goals for exercise with women's body image.

PubMed

Hurst, Megan; Dittmar, Helga; Banerjee, Robin; Bond, Rod

2017-03-01

Appearance goals for exercise are consistently associated with negative body image, but research has yet to consider the processes that link these two variables. Self-determination theory offers one such process: introjected (guilt-based) regulation of exercise behavior. Study 1 investigated these relationships within a cross-sectional sample of female UK students (n=215, 17-30 years). Appearance goals were indirectly, negatively associated with body image due to links with introjected regulation. Study 2 experimentally tested this pathway, manipulating guilt relating to exercise and appearance goals independently and assessing post-test guilt and body anxiety (n=165, 18-27 years). The guilt manipulation significantly increased post-test feelings of guilt, and these increases were associated with increased post-test body anxiety, but only for participants in the guilt condition. The implications of these findings for self-determination theory and the importance of guilt for the body image literature are discussed. Copyright © 2017 The Authors. Published by Elsevier Ltd..

The impact of inaccurate Internet health information in a secondary school learning environment.

PubMed

Kortum, Philip; Edwards, Christine; Richards-Kortum, Rebecca

2008-06-30

Patients in the United States commonly use the Internet to acquire health information. While a significant amount of health-related information is available on the Internet, the accuracy of this information is highly variable. The objective of the study was to determine how effectively students can assess the accuracy of Internet-based material when gathering information on a controversial medical topic using simple keyword searches. A group of 34 students from the science magnet high school in Houston, Texas searched for the terms "vaccine safety" and "vaccine danger" using Google and then answered questions regarding the accuracy of the health information on the returned sites. The students were also asked to describe the lessons they learned in the exercise and to answer questions regarding the strength of evidence for seven statements regarding vaccinations. Because of the surprising revelation that the majority of students left the exercise with inaccurate information concerning the safety and efficacy of vaccines, these same students participated in a follow-up study in which a fact-based vaccine video was shown, after which the assessment of student knowledge was repeated. Of the 34 participants, 20 (59%) thought that the Internet sites were accurate on the whole, even though over half of the links (22 out of 40, 55%) that the students viewed were, in fact, inaccurate on the whole. A high percentage of the students left the first exercise with significant misconceptions about vaccines; 18 of the 34 participants (53%) reported inaccurate statements about vaccines in the lessons they learned. Of the 41 verifiable facts about vaccines that were reported by participants in their lessons-learned statement, 24 of those facts (59%) were incorrect. Following presentation of the film, the majority of students left the exercise with correct information about vaccines, based on their lessons-learned statement. In this case, 29 of the 31 participants (94%) reported accurate information about vaccines. Of the 49 verifiable facts about vaccines that were reported by participants, only 2 (4%) were incorrect. Students had higher correct scores in the "strength of evidence" exercise following exposure to the video as well. Allowing students to use the Internet to gain information about medical topics should be approached with care since students may take away predominantly incorrect information. It is important to follow up conflicting information with a solid, unambiguous message that communicates those lessons that the instructor deems most important. This final message should be fact based but may need to contain an anecdotal component to counter the strong emotional message that is often delivered by inaccurate Internet sites.

Assessing a traditional case-based application exercise and a student question creation exercise on student performance and perceptions.

Tatachar, Amulya; Kominski, Carol

2017-07-01

To compare the impact of a traditional case-based application exercise with a student question creation exercise on a) student exam performance, b) student perceptions of enjoyment, competence, understanding, effort, interest in continuing participation, and interest in the subject. Subjects were 84 second-year pharmacy students in a pharmacotherapy course. The research focus was active learning involving the topic of chronic kidney disease-mineral bone disorder. Student teams were randomly assigned to either case-based or student question creation exercises using PeerWise. Student performance was assessed by a pre- and posttest and on block and final exams. After completion, an online survey assessed student perceptions of both exercises. Statistically significant differences were revealed in favor of the student question creation group on enjoyment and interest in the subject matter. No statistically differences were found between the traditional case-based group and the student question creation group on gain score from pre-test to posttest. The student question creation group performed slightly better than the case-based application group on two of the five questions on the block exam but none of these differences reached statistical significance. Students randomly assigned to groups that created and reviewed questions exhibited slightly improved summative exam performance and reported significantly more positive perceptions than students engaging in a more traditional case-based learning activity. Student question creation has demonstrated potential as a useful learning activity. Despite inherent difficulties in designing studies involving educational research in a controlled environment, students who have submitted, created, rated, and answered peers' questions have overall performed well.

Healthy Exercise Habits Are Associated With Lower Risk of Burnout and Higher Quality of Life Among U.S. Medical Students.

PubMed

Dyrbye, Liselotte N; Satele, Daniel; Shanafelt, Tait D

2017-07-01

Although burnout and low quality of life (QOL) are common among medical students, little remains known about personal fitness habits of medical students that may promote well-being. In 2012 the authors conducted a cross-sectional study of U.S. medical students to explore relationships between burnout, QOL, and compliance with Centers for Disease Control and Prevention (CDC) exercise recommendations. Wilcoxon-Mann-Whitney tests, Fisher exact tests, and multivariate logistic regression were performed. Among approximately 12,500 medical students invited to participate, 4,402 (35.2%) completed surveys. Most (2,738/4,367; 62.7%) engaged in aerobic exercise in accordance with CDC recommendations, while fewer (1,685/4,376; 38.5%) adhered to muscle strengthening recommendations. Burnout prevalence was lower among students who exercised aerobically consistent with CDC recommendations compared with those who exercised less (53.1% vs. 60.8%, P < .0001). Similarly, rates of burnout were also lower among students who strength trained consistent with CDC recommendations (51.8% vs. 58.6%, P < .0001). Overall QOL scores were higher for medical students adhering to CDC recommendations for aerobic exercise (7.2 vs. 6.6, P < .0001), strength training (7.2 vs. 6.8, P < .0001), or both aerobic and strength training (8.0 vs. 7.0, P < .0001). Compliance with CDC exercise guidelines remained independently associated with lower risk of burnout and higher QOL on multivariate analysis controlling for age, sex, relationship status, children, and year in school. Students whose aerobic exercise and/or strength training habits are consistent with CDC guidelines appear less likely to experience burnout and to have higher QOL.

The aim of the study was to examine the effectiveness of the smoking prevention program "I do not smoke, I exercise" implemented with elementary and secondary school students. "I do not smoke, I exercise" is a theory-based smoking prevention program that promotes exercise as an alternative of smoking. The program consists of eight sessions implemented weekly. Participants were 338 Greek students (135 elementary and 203 secondary students) who were pre- and posttested in smoking, program, and exercise-related measures. The results showed that the program had significant effects on elementary students' attitudes toward smoking, intention to smoke, subjective norms, attitudes toward the application of the program, and knowledge about the health consequences of smoking. For secondary students, significant effects were found on students' perceived behavioral control and knowledge about the health consequences of smoking, while very few students reported a smoking experience before and after the intervention. Therefore the program "I do not smoke, I exercise" may have positive effects on variables related with smoking behavior. Differences in the program's impact on elementary and secondary students were identified. All these are discussed with reference to the need of implementing smoking prevention programs in schools contexts. © 2016 Society for Public Health Education.

The primary measure used to determine relative effectiveness of in-class activities has been student performance on pre/posttests. However, in today’s active-learning classrooms, learning is a social activity, requiring students to interact and learn from their peers. To develop effective active-learning exercises that engage students, it is important to gain a more holistic view of the student experience in an active-learning classroom. We have taken a mixed-methods approach to iteratively develop and validate a 16-item survey to measure multiple facets of the student experience during active-learning exercises. The instrument, which we call Assessing Student Perspective of Engagement in Class Tool (ASPECT), was administered to a large introductory biology class, and student responses were subjected to exploratory factor analysis. The 16 items loaded onto three factors that cumulatively explained 52% of the variation in student response: 1) value of activity, 2) personal effort, and 3) instructor contribution. ASPECT provides a rapid, easily administered means to measure student perception of engagement in an active-learning classroom. Gaining a better understanding of students’ level of engagement will help inform instructor best practices and provide an additional measure for comprehensively assessing the impact of different active-learning strategies.

2017-09-01

Research on the benefits of visual learning has relied primarily on lecture-based pedagogy, but the potential benefits of combining active learning strategies with visual and verbal materials on learning anatomy has not yet been explored. In this study, the differential effects of text-based and image-based active learning exercises on examination performance were investigated in a functional anatomy course. Each class session was punctuated with an average of 12 text-based and image-based active learning exercises. Participation data from 231 students were compared with their examination performance on 262 questions associated with the in-class exercises. Students also rated the helpfulness and difficulty of the in-class exercises on a survey. Participation in the active learning exercises was positively correlated with examination performance (r = 0.63, P < 0.001). When controlling for other key demographics (gender, underrepresented minority status) and prior grade point average, participation in the image-based exercises was significantly correlated with performance on examination questions associated with image-based exercises (P < 0.001) and text-based exercises (P < 0.01), while participation in text-based exercises was not. Additionally, students reported that the active learning exercises were helpful for seeing images of key ideas (94%) and clarifying key course concepts (80%), and that the image-based exercises were significantly less demanding, less hard and required less effort than text-based exercises (P < 0.05). The findings confirm the positive effect of using images and active learning strategies on student learning, and suggest that integrating them may be especially beneficial for learning anatomy.

The purpose of this study was to clarify the subgroup differences in the association between participation in school-based extracurricular activities and exercise and levels of cigarette, alcohol, or marijuana use during one's lifetime and in the past year. This study also sought to determine the optimal classification of subgroups based on four variables (participation in school-based extracurricular activities, exercise, gender, and school year). Data consisted of a combined sample (aggregate sample) from the Japanese School Survey Project on Alcohol and Other Drugs (JSPAD) conducted in 2004, 2006, and 2009. The aggregate sample consisted of 75,726 1st-, 2nd-, and 3rd-year students (37,697 males and 38,029 females) at full-time high schools nationwide that were selected by stratified, single-stage cluster sampling during each survey. The aggregate sample combined randomly selected samples of the same size from each year the survey was conducted. Results indicated that 63.4% of the entire sample participated in school-based extracurricular activities, 64.8% of males did so, and 61.9% of females did so. Results also indicated that 66.4% of the entire sample exercised outside of PE class, 79.2% of males did so, and 53.8% of females did so. In addition, the prevalence of cigarette, alcohol, or marijuana use was predicted from the four variables by multiple logistic regression analysis. Results yielded optimal subgroups for the prevalence of each drug's use. Results revealed (1) that participation in school-based extracurricular activities and gender were more predictive, whereas exercise was least predictive, (2) that the association between exercise and substance use measures varies subtly for each subgroup, suggesting the existence of a great variety of opportunities for high school students to exercise, and (3) that school year had a substantial and positive effect on drinking among students who actively participated in school-based extracurricular activities.

Young adulthood is characterized by profound life-style changes. This study suggests that reduction of sport or exercise, induced by alteration of the occupational situation, negatively impacts generation/maintenance of peak bone mass. In order to compensate occupational-related reductions of physical activity, workplace exercise programs will be helpful. Only few studies have determined the effect of physical activity or physical exercise on bone mineral density (BMD) in the period of late skeletal maturation, i.e. around peak bone mass. The aim of this article was to determine the long-term effect of different levels of physical activity and exercise directly and indirectly derived by occupation during young adulthood. Sixty-one male and female dental students (DES) and 53 male and female sport students (SPS) 21±2 years old were accompanied over the course (4.8±0.5 years) of their study program. BMD at the lumbar spine (LS), hip, and whole body (WB) were determined using dual-energy X-ray absorptiometry. Parameters of physical activity increased non-significantly in both groups with no relevant differences between the groups. Indices of exercise, however, increased significantly in the SPS group while a significant decrease was assessed for the DES group. Independent of gender, BMD of the SPS increased significantly (p≤0.007) at all skeletal sites (LS, 2.4±3.9%; hip, 1.6±3.5%; WB, 1.8±2.8%) while BMD of the DES remained unchanged at LS (-0.6±4.4%, p=0.432) and WB (0.5±1.9%, p=0.092) but decreased significantly at the hip (-1.9±4.3%, p=0.010). BMD-changes at LS, hip, and WB differ significantly between SPS and DES (p≤0.017). Results remained unchanged after adjusting for baseline BMD-values that differed (p=0.030 to p=0.082) in favor of the SPS group. Changes of exercise levels directly or indirectly caused by occupational factors during young adulthood significantly affected generation and/or maintenance of peak bone mass. Compensatory exercise is thus highly relevant for bone health of young adults.

We have developed a new type of handcraft exercise program that aims to stimulate student's creativity on the way of design and fabrication of the subject machines. Conventional handicraft exercise program used to aim at letting students learn procedures of machining operation in accordance with a designated manual. Students having experienced our conventional exercise did not fully satisfied at those programs because of the lack in a room for their idea and creativity. Authors, a group of both technical and academic staffs, have developed and started the new type of program since 2003 at the Creation Plaza in Nagoya University. Developed program is classified into grades according to the difference in technical contents required for students.

Previous studies on team-based learning (TBL) in medical education demonstrated improved learner engagement, learner satisfaction, and academic performance; however, a paucity of information exists on modifications of the incentive structure of "traditional" TBL practices. The current study investigates the impact of modification to conventional Group Application exercises by examining student preference and student perceptions of TBL outcomes when Group Application exercises are excluded from TBL grades. During the 2009-2010 and 2010-2011 academic years, 175 students (95.6% response rate) completed a 22-item multiple choice survey followed by 3 open response questions at the end of their second year of medical school. These students had participated in a TBL supplemented preclinical curriculum with graded Group Application exercises during year one and ungraded Group Application exercises during year two of medical school. Chi-square analyses showed significant differences between grading categories for general assessment of TBL, participation and communication, intra-team discussion, inter-team discussion, student perceptions of their own effort and development of teamwork skills. Furthermore, 83.8% of students polled prefer ungraded Group Application exercises with only 7.2% preferring graded and 9.0% indicating no preference. The use of ungraded Group Application exercises appears to be a successful modification of TBL, making it more "student-friendly" while maintaining the goals of active learning and development of teamwork skills.

Knowledge of baseline laparoscopic and robotic surgical skills of future learners is essential to develop teaching strategies that best fit them. The objectives of this study are to determine baseline laparoscopic and robotic skills of high school and college students and compare them to those of current obstetrics and gynecology residents. A cross-sectional (Class II-2) pilot study. Laparoscopic and robotic surgical skills of college and high (secondary) school students were evaluated using simulators and compared to those of obstetrics and gynecology residents. In addition, questionnaire data were collected regarding video game playing and computer use. A total of 17 students, both high school (n=9) and college (n=8), in addition to 11 residents, completed the study. Overall, students performed comparably to the residents in simple exercises (p>.05). However, students took significantly longer time to complete complex exercises (p=.001). Finally, students played video games significantly more than residents (p<.001). Future learners may have a different background skill set. This difference may be related to improved hand-eye coordination, possibly due to playing video games. The results of this pilot study should spur more research into surgical teaching strategies.

Objective. To determine whether a high-fidelity simulation technique compared with lecture would produce greater improvement in advanced cardiac life support (ACLS) knowledge, confidence, and overall satisfaction with the training method. Design. This sequential, parallel-group, crossover trial randomized students into 2 groups distinguished by the sequence of teaching technique delivered for ACLS instruction (ie, classroom lecture vs high-fidelity simulation exercise). Assessment. Test scores on a written examination administered at baseline and after each teaching technique improved significantly from baseline in all groups but were highest when lecture was followed by simulation. Simulation was associated with a greater degree of overall student satisfaction compared with lecture. Participation in a simulation exercise did not improve pharmacy students’ knowledge of ACLS more than attending a lecture, but it was associated with improved student confidence in skills and satisfaction with learning and application. Conclusions. College curricula should incorporate simulation to complement but not replace lecture for ACLS education. PMID:23610477

Previous research has reported the existence of disordered eating in students studying nutrition and dietetics. However, the occurrence of exercise addiction, previously linked to disordered eating, is poorly understood in this group. The main objective of this study was to explore the prevalence of self-reported symptoms of exercise addiction and the association with disordered eating in a sample of students studying nutrition and dietetics. A secondary objective was to compare the prevalence of exercise addiction to students enrolled in another health-related degree. We conducted a cross-sectional study in 165 undergraduate students. Participants were students of both sexes enrolled in nutrition and dietetics and occupational therapy degree programs at an Australian university in August 2013. Participants completed four validated questionnaires for assessment of exercise- and eating-related attitudes and behaviors measuring scores for exercise addiction, weekly volume of physical activity (PA), eating disorder symptoms, and cognitive restraint. Stretch stature and body mass were measured and body composition was assessed using dual energy x-ray absorptiometry. Independent t test, Mann-Whitney U test, and χ 2 test were completed to compare groups of students based on sex, degree, or eating attitudes. Spearman's correlation was performed to explore associations between continuous variables (exercise addiction scores, PA volume, and scores for eating attitudes and cognitive restraint). Approximately 23% of nutrition and dietetics students were found to be at risk of exercise addiction (20% females and 35% males; P=0.205), while the majority demonstrated some symptoms of exercise addiction. A similar proportion of at risk individuals was found in the female occupational therapy group (19%; P=1.000). In females (nutrition and dietetics and occupational therapy combined), the exercise addiction scores were associated with three other outcome measures: PA volume (r s =0.41; P<0.001), eating attitudes scores (r s =0.24; P=0.008), and cognitive restraint (r s =0.32; P<0.001). Comparative analysis indicated that female students with high cognitive restraint had greater exercise addiction scores than those with low cognitive restraint (20.3 [4.8] compared to 17.8 [4.2]; P=0.003). Results suggest high prevalence of exercise addiction in this sample of undergraduate health-related degree students and its link to amount of PA and disordered eating in females. Future research should include larger samples of both sexes to build the existing understanding on these maladaptive behaviors. Copyright © 2017 Academy of Nutrition and Dietetics.

Stanek, Justin; Rogers, Katherine; Anderson, Jordan

2015-01-01

Context: Researchers have examined the physical activity (PA) habits of certified athletic trainers; however, none have looked specifically at athletic training students. Objective: To assess PA participation and constraints to participation among athletic training students. Design: Cross-sectional study. Setting: Entry-level athletic training education programs (undergraduate and graduate) across the United States. Patients or Other Participants: Participants were 1125 entry-level athletic training students. Main Outcome Measure(s): Self-reported PA participation, including a calculated PA index based on a typical week. Leisure constraints and demographic data were also collected. Results: Only 22.8% (252/1105) of athletic training students were meeting the American College of Sports Medicine recommendations for PA through moderate-intensity cardiorespiratory exercise. Although 52.3% (580/1105) were meeting the recommendations through vigorous-intensity cardiorespiratory exercise, 60.5% (681/1125) were meeting the recommendations based on the combined total of moderate or vigorous cardiorespiratory exercise. In addition, 57.2% (643/1125) of respondents met the recommendations for resistance exercise. Exercise habits of athletic training students appear to be better than the national average and similar to those of practicing athletic trainers. Students reported structural constraints such as lack of time due to work or studies as the most significant barrier to exercise participation. Conclusions: Athletic training students experienced similar constraints to PA participation as practicing athletic trainers, and these constraints appeared to influence their exercise participation during their entry-level education. Athletic training students may benefit from a greater emphasis on work-life balance during their entry-level education to promote better health and fitness habits. PMID:25689560

Training students in serologic reaction grading increased perceptions of self-efficacy and ability to recognize serologic reactions but decreased grading accuracy.

PubMed

Perry, Holly; Henry, Stephen

2015-06-01

The ability to recognize and grade serologic reactions in manual techniques remains an important skill both for reference laboratories and in disaster-relocated laboratory services. Developing skills in recognizing and grading serologic reactions is limited to some extent by the range of samples available. Twenty-six students studying transfusion science were presented with blinded grading panels consisting of mixes of natural cells and kodecytes (natural cells modified with synthetic blood group antigens) representing a range of serologic grades. Results from 15-minute exercises over 17 contact weeks were assessed to determine if training with grading panels would have an impact on the ability of students to recognize and correctly grade serologic reactions. Twenty-one clinically active practitioners also took part in a single analysis. Grading exercises found that the use of kodecytes and natural negative cells were able to identify deficiencies in both students' and practitioners' ability to recognize negative and grade serologic reactions. The seventeen 15-minute exercises undertaken with students revealed that although there was some improvement in performance in recognizing positive and negative serologic reactions there was also a degradation in ability to accurately grade. Self-assessment showed a major improvement in students' self-efficacy. The use of serologic grading panels created with kodecytes was suitable as a tool to recognize and monitor serologic grading abilities. Evidence suggests that for both students and practitioners to gain and sustain competency in serologic reaction recognition and grading, they will require ongoing training and monitoring of competence. © 2015 AABB.

Ito, Yukiko; Hiramoto, Izumi; Kodama, Hideya

2017-09-01

In Japan, dance exercise has been introduced as a compulsory element of health and physical education, but there is a considerable discrepancy in the levels of performance among students with intellectual disability (ID) at special needs schools. The aim of this study was therefore to identify the factors affecting the performance of dance exercise in students with ID. A 4 month dance exercise program was implemented for junior high school students at a special needs school, and the performance of 32 students at 22 sessions was assessed quantitatively according to calorie use during exercise and performance proficiency score. The measures were compared according to gender, age, body mass index, diagnosis, and development quotient (DQ) score. Performance in many students improved with repetition and reached the highest attainment level at around the third month. Male gender and older age had a significant positive impact on calorie use, whereas diagnosis of Down syndrome and higher DQ score had a significant positive impact on proficiency score. Four students with poor performance were all female students with autism. This study provides some possible explanations for differences in the levels of dance performance among students with ID. © 2017 Japan Pediatric Society.

Background : Self-rated health (SRH) is consistent with objective health status and can serve as a global measure of health status in the general population. The purpose of this study is to find the connections of dietary habits, leisure-time exercise, exercise attitude, and body mass index (BMI) to SRH among college students. Methods : The "dietary⁻exercise attitude and SRH" questionnaire was developed to investigate college students in Taiwan through the Internet. Partial least squares structural equation modeling (PLS-SEM) was used to test the relationship among them. Results : The reliability and validity were confirmed using PLS-SEM. The results found exercise habits, dietary habits, and BMI explained 26.5% of SRH. Poor dietary habits and being overweight led to bad health status (negative path coefficients to SRH). Additionally, the study found that positive exercise attitude had a positive relationship with exercise habits. Conclusions : Based on the results, college students should be well-informed of the potential threat of poor dietary habits and being overweight to health and should improve their attitude with respect to exercise so as to prevent overweight-related diseases.

Kim, Sang Dol

2018-05-01

To assess the effects of yogic exercise on nonspecific neck pain in university students. This study is a pretest-posttest design with a non-equivalent control group. Thirty-eight university students were selected by convenience sampling, with 18 assigned to an exercise group and 20 assigned to a control group. The yoga group participated in one-hour sessions of yogic exercise two days a week for eight weeks. The exercise comprised eight stages: relaxation, flexion of neck, extension of neck, right lateral flexion of neck, left lateral flexion of neck, right rotation of neck, left rotation of neck, and relaxation. Neck pain intensity was measured using a 100 mm visual analogue scale. The yoga group showed significantly decreased neck pain scores compared with those of the control group. These findings indicate that yogic exercises could reduce neck pain in university students. Copyright © 2017 Elsevier Ltd. All rights reserved.

Depression among nursing students is an ongoing problem. Several psychotherapies have been suggested as alternatives to antidepressants in the management of depression. The aim of this randomized controlled study was to compare the effectiveness of mindfulness meditation versus physical exercise in the management of depression among nursing students. A sample of 181 soon-to-graduate nursing students participated in the study and were assigned at random to one of two therapies: physical exercise (n = 90) or mindfulness meditation (n = 91). The Center for Epidemiologic Studies Depression Scale was completed by the participants in both groups prior to the therapies and after completion. The findings indicated that both therapies were effective in the management of depression. However, mindfulness meditation is more effective than physical exercise. Mindfulness meditation is recommended over physical exercise in the management of depression among undergraduate nursing students. [J Nurs Educ. 2017;56(10):599-604.].

Objective To determine the impact of the Patient Empathy Modeling pedagogy on students' empathy towards caring for the underserved during an advanced pharmacy practice experience (APPE). Design Pharmacy students completing an APPE at 2 primary care clinics participated in a Patient Empathy Modeling assignment for 10 days. Each student “became the patient,” simulating the life of an actual patient with multiple chronic diseases who was coping with an economic, cultural, or communication barrier to optimal healthcare. Students completed the Jefferson Scale of Physician Empathy (JSPE) before and after completing the assignment, and wrote daily journal entries and a reflection paper. Assessment Twenty-six students completed the PEM exercises from 2005-2006. Scores on the JSPE improved. Students' comments in journals and reflection papers revealed 3 major themes: greater appreciation of the difficulty patients have with adherence to medication and treatment regimens, increased empathy for patients from different backgrounds and patients with medical and psychosocial challenges, and improved ability to apply the lessons learned in the course to their patient care roles. Conclusion A Patient Empathy Modeling assignment improved pharmacy students' empathy toward underserved populations. Integrating the assignment within an APPE allowed students to immediately begin applying the knowledge and insight gained from the exercise. PMID:18483606

Effective social problem-solving abilities can contribute to decreased risk of poor mental health. In addition, physical activity has a favorable effect on mental health. These previous studies suggest that physical activity and social problem-solving ability can interact by helping to sustain mental health. The present study aimed to determine the association between attitude and practice of physical activity and social problem-solving ability among university students. Information on physical activity and social problem-solving was collected using a self-administered questionnaire. We analyzed data from 185 students who participated in the questionnaire surveys and psychological tests. Social problem-solving as measured by the Social Problem-Solving Inventory-Revised (SPSI-R) (median score 10.85) was the dependent variable. Multiple logistic regression analysis was employed to calculate the odds ratios (ORs) and 95% confidence intervals (CIs) for higher SPSI-R according to physical activity categories. The multiple logistic regression analysis indicated that the ORs (95% CI) in reference to participants who said they never considered exercising were 2.08 (0.69-6.93), 1.62 (0.55-5.26), 2.78 (0.86-9.77), and 6.23 (1.81-23.97) for participants who did not exercise but intended to start, tried to exercise but did not, exercised but not regularly, and exercised regularly, respectively. This finding suggested that positive linear association between physical activity and social problem-solving ability (p value for linear trend < 0.01). The present findings suggest that regular physical activity or intention to start physical activity may be an effective strategy to improve social problem-solving ability.

Using social cognitive theory to explain discretionary, "leisure-time" physical exercise among high school students.

Winters, Eric R; Petosa, Rick L; Charlton, Thomas E

2003-06-01

To examine whether knowledge of high school students' actions of self-regulation, and perceptions of self-efficacy to overcome exercise barriers, social situation, and outcome expectation will predict non-school related moderate and vigorous physical exercise. High school students enrolled in introductory Physical Education courses completed questionnaires that targeted selected Social Cognitive Theory variables. They also self-reported their typical "leisure-time" exercise participation using a standardized questionnaire. Bivariate correlation statistic and hierarchical regression were conducted on reports of moderate and vigorous exercise frequency. Each predictor variable was significantly associated with measures of moderate and vigorous exercise frequency. All predictor variables were significant in the final regression model used to explain vigorous exercise. After controlling for the effects of gender, the psychosocial variables explained 29% of variance in vigorous exercise frequency. Three of four predictor variables were significant in the final regression equation used to explain moderate exercise. The final regression equation accounted for 11% of variance in moderate exercise frequency. Professionals who attempt to increase the prevalence of physical exercise through educational methods should focus on the psychosocial variables utilized in this study.

Utilizing visual art to enhance the clinical observation skills of medical students.

Jasani, Sona K; Saks, Norma S

Clinical observation is fundamental in practicing medicine, but these skills are rarely taught. Currently no evidence-based exercises/courses exist for medical student training in observation skills. The goal was to develop and teach a visual arts-based exercise for medical students, and to evaluate its usefulness in enhancing observation skills in clinical diagnosis. A pre- and posttest and evaluation survey were developed for a three-hour exercise presented to medical students just before starting clerkships. Students were provided with questions to guide discussion of both representational and non-representational works of art. Quantitative analysis revealed that the mean number of observations between pre- and posttests was not significantly different (n=70: 8.63 vs. 9.13, p=0.22). Qualitative analysis of written responses identified four themes: (1) use of subjective terminology, (2) scope of interpretations, (3) speculative thinking, and (4) use of visual analogies. Evaluative comments indicated that students felt the exercise enhanced both mindfulness and skills. Using visual art images with guided questions can train medical students in observation skills. This exercise can be replicated without specially trained personnel or art museum partnerships.

2001-04-01

The traditional lab exercise that achieves separation of a mixture of 4-aminoacetophenone and benzoic acid by chemically active extraction has been expanded to include two exercises. First, students provide input on condition selections. This is based on the pooling of data from student observations of the solubility-miscibility behavior of 4-aminoacetophenone, benzoic acid, sodium benzoate, and various solvents and aqueous solutions. Second, students participate in an exercise that uses materials from the extraction experiment to simulate how a virus spreads through a population. The additional mini-exercises promote student participation and reinforce the concepts of the extraction lab.

Student construction of small molecule models using Spartan Model to explore polarity

2006-12-01

This study compared the attitudes and the gains of knowledge concerning Lewis structures and polarity of molecules. The students performed a lab exercise in which they drew Lewis structures, constructed models of the molecules, determined the geometry of the molecules, and determined the polarity of the molecules. The control group students constructed models using physical ball-and-stick models. The treatment group students used Spartan Model to construct models. Students from a university and a community college participated in this study. Four lab classes at each school made up the treatment group. Five lab classes at the university and three lab classes at the community college made up the control group. The treatment group classes were selected based on available computer resources. All students in the study were given the Lab Pre Test, Lab Post Test, and the Lecture Post Test to assess the student's ability to answer questions pertaining to Lewis structures and polarity of molecules. An Attitudinal Survey assessed the attitudes of the students who participated in the study. Student interviews were performed to assess the student's attitudes towards the lab exercise. The interviews investigated attitudes about the modeling exercise, Lewis structures, and polarity of molecules. There were no significant differences in the performance of the treatment group when compared to the control group on the performance assessment instruments at the university or the community college. The treatment group students at the university had a more positive attitude about the lab activity. They believed that the lab activity helped them better understand the concepts of Lewis structure and molecular polarity. At the community college, the control group students had a more positive attitude about the lab activity. The students involved in the study believed that the lab activity helped them to understand the concepts of molecular geometry and polarity. The interviews of the treatment group students indicated that they strongly believed that the lab activity helped them better understand the concept of Lewis structures and of molecular polarity. As reflected in the interviews of the treatment group and the control group, the lab activity did not help the students be able to look at a Lewis structure and build a mental image of the molecule. The students believed the electrostatic potential plots generated by Spartan Model were very insightful into the concept of polarity. It gave them a visual representation of a difficult topic.

To determine the stress that is potentially produced in professional health workers due to a mass casualty incident (MCI) simulated exercise, and its relation to prior academic training and the role played in the simulation. Observational study of stress in a MCI. For this work, two MCI drills comprised of 40 victims each were conducted. Two randomized groups of 36 students each were created: Master's Students Group (MSG) and Undergraduate Student Group (USG). The role performed by each student (triage or sectorization) was assessed. The stress level was determined by prior and subsequent measurements of alpha-amylase (αA), HR, SBP and DBP. The percentage of victims that were correctly triaged was 88.6%, 91.84% for MSG and 83.76% for the USG (p=0.004). The basal αA was 97,107.50±72,182.67IU/L and the subsequent αA was 136,195.55±90,176.46±IU/L (p<0.001). The baseline HR was 78.74±14.92beats/min and the subsequent HR was 95.65±23.59beats/min (p=0.000). We found significant differences in the αA between students who performed the triage and those who performed sectorization but there were no differences between undergraduate and Masters' students. Conducting a simulated exercise caused stress in personnel involved in the MCI, with a greater impact on participants who performed triage, although it was not influenced by their prior academic level. The stress level in our case did not affect or determine the performance of acquired skills. Copyright © 2017 Elsevier Ltd. All rights reserved.

2016-01-01

The purpose of this study was to use the body painting method to teach hand anatomy to a group of preclinical medical students. Students reviewed hand anatomy using the traditional method and body painting exercise. Feedback and retention of the anatomy-related information were examined by a questionnaire and multiple-choice questions, respectively, immediately and 1 month after the painting exercise. Students agreed that the exercise was advantageous and helped facilitate self-active learning after in-class anatomy lessons. While there was no significant difference in knowledge retention between the control and experimental groups, the students appreciated the exercise in which they applied body paint to the human body to learn anatomy. The body painting was an efficient tool for aiding the interactive learning of medical students and increasing the understanding of gross anatomy.

Health perceptions, self and body image, physical activity and nutrition among undergraduate students in Israel.

2013-01-01

This study examines health perceptions, self and body image, physical exercise and nutrition among undergraduate students. A structured, self-reported questionnaire was administered to more than 1500 students at a large academic institute in Israel. The study population was heterogenic in both gender and fields of academic study. High correlations between health perceptions, appropriate nutrition, and positive self and body image were found. The relationships between these variables differed between the subpopulation in the sample and the different genders. Engagement in physical exercise contributed to positive body image and positive health perceptions more than engagement in healthy nutrition. Nutrition students reported higher frequencies of positive health perceptions, positive self and body image and higher engagement in physical exercise in comparison to all other students in the sample. This study suggests, as have many before, that successful health promotion policy should reflect a collectivist rather than an individualist ethos by providing health prerequisites through a public policy of health-promotion, where the academic settings support a healthy lifestyle policy, by increasing availability of a healthy, nutritious and varied menu in the cafeterias, and offering students various activities that enhance healthy eating and exercise. IMPLICATIONS AND CONTRIBUTION: This study examined health perceptions, self-image, physical exercise and nutrition among undergraduate students and found high correlations between these topics. Nutrition students reported higher frequencies of positive health perceptions, and positive self and body image and engaged more in physical exercise when compared with all other students in the sample.

Blood flow patterns during incremental and steady-state aerobic exercise.

Endothelial shear stress (ESS) is a physiological stimulus for vascular homeostasis, highly dependent on blood flow patterns. Exercise-induced ESS might be beneficial on vascular health. However, it is unclear what type of ESS aerobic exercise (AX) produces. The aims of this study are to characterize exercise-induced blood flow patterns during incremental and steady-state AX. We expect blood flow pattern during exercise will be intensity-dependent and bidirectional. Six college-aged students (2 males and 4 females) were recruited to perform 2 exercise tests on cycleergometer. First, an 8-12-min incremental test (Test 1) where oxygen uptake (VO2), heart rate (HR), blood pressure (BP), and blood lactate (La) were measured at rest and after each 2-min step. Then, at least 48-hr. after the first test, a 3-step steady state exercise test (Test 2) was performed measuring VO2, HR, BP, and La. The three steps were performed at the following exercise intensities according to La: 0-2 mmol/L, 2-4 mmol/L, and 4-6 mmol/L. During both tests, blood flow patterns were determined by high-definition ultrasound and Doppler on the brachial artery. These measurements allowed to determine blood flow velocities and directions during exercise. On Test 1 VO2, HR, BP, La, and antegrade blood flow velocity significantly increased in an intensity-dependent manner (repeated measures ANOVA, p<0.05). Retrograde blood flow velocity did not significantly change during Test 1. On Test 2 all the previous variables significantly increased in an intensity-dependent manner (repeated measures ANOVA, p<0.05). These results support the hypothesis that exercise induced ESS might be increased in an intensity-dependent way and blood flow patterns during incremental and steady-state exercises include both antegrade and retrograde blood flows.

2017-01-01

Applied research experiences can provide numerous benefits to undergraduate students, however few studies have assessed the perceptions of Exercise Science (EXS) students to an applied research experience. The purpose of this study was two-fold: 1) to describe the rationale and implementation of an applied research experience into an EXS curriculum and 2) to evaluate EXS undergraduate students' perceptions of an applied research experience. An EXS measurement course was chosen for implementation of an applied research experience. The applied research experience required groups of students to design, implement, and evaluate a student-led research project. Fourteen questions were constructed, tailored to EXS undergraduate students, to assess students' perceptions of the experience. Qualitative analysis was used for all applicable data, with repeated trends noted; quantitative data were collapsed to determine frequencies. There was an overall positive student perception of the experience and 85.7% of students agreed an applied research experience should be continued. 84.7% of students perceived the experience as educationally enriching, while 92.8% reported the experience was academically challenging. This experience allowed students to develop comprehensive solutions to problems that arose throughout the semester; while facilitating communication, collaboration, and problem solving. Students believed research experiences were beneficial, but could be time consuming when paired with other responsibilities. Results suggest an applied research experience has the potential to help further the development of EXS undergraduate students. Understanding student perceptions of an applied research experience may prove useful to faculty interested in engaging students in the research process.

2018-01-01

Children with autism spectrum disorder (ASD) are at risk for obesity, commonly have sleep disorders, and exhibit stereotypic behaviors that disrupt their learning. Vigorous levels of exercise have been shown to ameliorate these issues in children with ASD, but little research exists to provide techniques for motivating children with ASD to engage in exercise. The present study examined the effect of music on exercise intensity in a group of 13 elementary school students with ASD. Data were collected across six days during structured (e.g., verbal and physical prompts) and unstructured (e.g., minimal prompting) exercise periods. During these exercise periods, three music conditions were randomized: no music, slow-tempo music, and fast-tempo music. Exercise intensity, measured in Metabolic Equivalent of Tasks by triaxial accelerometers, was greatest during the structured exercise periods and during the slow music condition. Student characteristics moderated the impact of music condition on exercise intensity, such that students with high levels of adaptive behavior or lower levels of maladaptive behavior displayed greater exercise intensity during the fast music condition.

2014-01-01

This article examines the relation of contemplative exercises with enhancement of students' experience during neuroscience studies. Short contemplative exercises inspired by the Buddhist tradition of self-inquiry were introduced in an undergraduate neuroscience course for psychology students. At the start of the class, all students were asked to participate in short “personal brain investigations” relevant to the topic presented. These investigations were aimed at bringing stable awareness to a specific perceptual, emotional, attentional, or cognitive process and observing it in a non-judgmental, non-personal way. In addition, students could choose to participate, for bonus credit, in a longer exercise designed to expand upon the weekly class activity. In the exercise, students continued their “personal brain investigations” for 10 min a day, 4 days a week. They wrote “lab reports” on their daily observations, obtained feedback from the teacher, and at the end of the year reviewed their reports and reflected upon their experiences during the semester. Out of 265 students, 102 students completed the bonus track and their final reflections were analyzed using qualitative methodology. In addition, 91 of the students answered a survey at the end of the course, 43 students participated in a quiz 1 year after course graduation, and the final grades of all students were collected and analyzed. Overall, students reported satisfaction from the exercises and felt they contributed to their learning experience. In the 1-year follow-up, the bonus-track students were significantly more likely than their peers to remember class material. The qualitative analysis of bonus-track students' reports revealed that the bonus-track process elicited positive feelings, helped students connect with class material and provided them with personal insights. In addition, students acquired contemplative skills, such as increased awareness and attention, non-judgmental attitudes, and better stress-management abilities. We provide examples of “personal brain investigations” and discuss limitations of introducing a contemplative approach. PMID:25477833

The graduate medical students often get less opportunity for clarifying their doubts and to reinforce their concepts after lecture classes. Assessment of the effect of MCQ preparation by graduate medical students as a revision exercise on the topic "Mineral metabolism." At the end of regular teaching module on the topic "Mineral metabolism," graduate medical students were asked to prepare the stems of 15 MCQs based on the four discriminators given for each. They were told that one of the discriminators could be the answer for the MCQ and the remaining three could be the distracters. They were further guided in their task by providing few key word(s) in the stem of the expected MCQ. In the first phase of the exercise, the students attempted the MCQ preparation individually without peer consultation. In the second phase, the students participated in small group discussion to formulate the best MCQs of the group. The effects on low, medium, and high achievers were evaluated by pre and post-tests with the same set of MCQs. Both the individual endeavor in Phase 1 and small group discussion in Phase 2 for the formulation of MCQs significantly contributed to the gain from the exercise. The gains from the individual task and from small group discussion were equal among the different categories of students. Both phases of the exercise were equally beneficial for the low, medium, and high achievers. The high and medium achievers retained the gain from the exercise even after 1 week of the exercise whereas the low achievers could not retain the gain completely. Formulation of MCQs is an effective and useful unconventional revision exercise in Biochemistry for graduate medical students. Copyright © 2012 Wiley Periodicals, Inc.

Simulation provides opportunities for midwifery students to enhance their performance in emergency situations. Neonatal resuscitation is one such emergency and its management is a major concern for midwifery students. This project aimed to develop and evaluate a simulation exercise, for neonatal resuscitation, for 3rd year midwifery students. A quantitative survey design was employed using questions from two previously validated questionnaires: (1.) Student Satisfaction and Self-Confidence in Learning and (2.) the Clinical Teamwork Scale (CTS). Australian university. 40 final year midwifery students were invited to participate and 36 agreed to take part in the project. In pre-simulation questionnaires, students reported low levels of confidence in initiating care of an infant requiring resuscitation. Most anticipated that the simulation exercise would be useful to better prepare them respond to a neonatal emergency. Post-simulation questionnaires reported an increase in student confidence, with 30 of 36 students agreeing/ strongly agreeing that their confidence levels had improved. Nonetheless, an unexpected number of students reported a lack of familiarity with the equipment. The single simulation exercise evaluated in this project resulted in improved student confidence and greater knowledge and skills in neonatal resuscitation. However, deficits in handling emergency equipment, and in understanding the role of the student midwife/midwife in neonatal resuscitation, were also noted. For the future, the development and evaluation of a programme of simulation exercises, over a longer period, is warranted. This approach may reduce stress and better address student learning needs.

To investigate if a virtual laboratory simulation (vLAB) could be used to replace a face to face tutorial (demonstration) to prepare students for a laboratory exercise in microbiology. A total of 189 students who were participating in an undergraduate biology course were randomly selected into a vLAB or demonstration condition. In the vLAB condition students could use a vLAB at home to 'practice' streaking out bacteria on agar plates in a virtual environment. In the demonstration condition students were given a live demonstration from a lab tutor showing them how to streak out bacteria on agar plates. All students were blindly assessed on their ability to perform the streaking technique in the physical lab, and were administered a pre and post-test to determine their knowledge of microbiology, intrinsic motivation to study microbiology, and self-efficacy in the field of microbiology prior to, and after the experiment. The results showed that there were no significant differences between the two groups on their lab scores, and both groups had similar increases in knowledge of microbiology, intrinsic motivation to study microbiology, as well as self-efficacy in the field of microbiology. Our data show that vLABs function just as well as face to face tutorials in preparing students for a physical lab activity in microbiology. The results imply that vLABs could be used instead of face to face tutorials, and a combination of virtual and physical lab exercises could be the future of science education.

2006-10-01

The purpose of the study was to evaluate the effects of a Social Cognitive Theory-based intervention designed to increase the frequency of leisure time planned moderate and vigorous physical exercise among rural high school students attending physical education class. Students in treatment and comparison groups were exposed to an activity-based physical education curricula. The treatment group received eight behavioral skill-building lessons integrated into the existing curriculum. The Social Cognitive Theory-based educational treatment increased levels of moderate physical exercise occurring outside the classroom. This study demonstrated an impact on adolescent leisure time moderate physical exercise using classroom instruction. The intervention was most effective with students who were previously sedentary. The curricular approaches used to promote regular moderate exercise may be useful for sedentary adolescents.

Roche, Victoria F.; Qi, Yongyue

2016-01-01

Objective. To analyze student perceptions of self-efficacy in meeting medicinal chemistry course related educational outcomes and skills following a medicinal chemistry skills laboratory. Methods. Four activities were implemented in a pharmacy skills laboratory (PSL) for second-year pharmacy students. Students (n=121) worked individually on exercises for three of the four activities. Pre/post-laboratory surveys on self-efficacy were administered. The McNemar test was performed to evaluate students’ self-efficacy above 70% related to course outcomes before and after the exercises in each activity. An independent t test was conducted to compare the mean of students’ responses on meeting course outcomes based on the 70% anchor for the perspective confidence on meeting course outcomes. Results. The post-PSL scores on all self-efficacy questions improved. The majority of students reported skill development in all exercises. Students and clinical faculty qualitative responses indicated they felt exercises were effective. Conclusion. A PSL can serve as a valuable opportunity to address course related educational outcomes and specific skill development and can help students assess their self-efficacy in meeting them.

Simulation exercises have long been used to teach management skills in business schools. However, this pedagogical approach has not been reported in emergency medical services (EMS) management education. We sought to develop, deploy, and evaluate a computerized simulation exercise for teaching EMS management skills. Using historical data, a computer simulation model of a regional EMS system was developed. After validation, the simulation was used in an EMS management course. Using historical operational and financial data of the EMS system under study, students designed an EMS system and prepared a budget based on their design. The design of each group was entered into the model that simulated the performance of the EMS system. Students were evaluated on operational and financial performance of their system design and budget accuracy and then surveyed about their experiences with the exercise. The model accurately simulated the performance of the real-world EMS system on which it was based. The exercise helped students identify operational inefficiencies in their system designs and highlighted budget inaccuracies. Most students rated the exercise as moderately or very realistic in ambulance deployment scheduling, budgeting, personnel cost calculations, demand forecasting, system design, and revenue projections. All students indicated the exercise was helpful in gaining a top management perspective, and 89% stated the exercise was helpful in bridging the gap between theory and reality. Preliminary experience with a computer simulator to teach EMS management skills was well received by students in a baccalaureate paramedic program and seems to be a valuable teaching tool.

The purpose of this study was to assess exercise motivation among college students self-selected into 4 online (OL) and face-to-face (F2F) basic studies' physical activity and wellness course delivery formats. Out of 1,037 enrolled students during the Spring 2009 semester, 602 responded online to demographic questions and to the Behavioural Regulation in Exercise Questionnaire, which assessed exercise motivation on 5 subscales. There were no significant differences (p > .05) in exercise motivation for students across course delivery formats, but there was a significant difference in age and employment status between the completely OL and F2F course formats. Health and physical educators can utilize these findings to better understand that physical activity and wellness students are not necessarily trying to avoid physical activity when selecting the OL course format, but are more likely trying to balance work and school responsibilities and need greater flexibility in time and location.

Background The purpose of this study was to use the body painting method to teach hand anatomy to a group of preclinical medical students. Methods Students reviewed hand anatomy using the traditional method and body painting exercise. Feedback and retention of the anatomy-related information were examined by a questionnaire and multiple-choice questions, respectively, immediately and 1 month after the painting exercise. Results Students agreed that the exercise was advantageous and helped facilitate self-active learning after in-class anatomy lessons. While there was no significant difference in knowledge retention between the control and experimental groups, the students appreciated the exercise in which they applied body paint to the human body to learn anatomy. Conclusion The body painting was an efficient tool for aiding the interactive learning of medical students and increasing the understanding of gross anatomy.

Verkooijen, Kirsten T; de Bruijn, Gert-Jan

2013-01-01

Possible interactions among exercise self-identity, social comparison and exercise behaviour were explored in a sample of 417 undergraduate students (mean age = 21.5, SD = 3.0; 73% female). Two models were examined using self-report data; (1) a mediation model which proposed an association between social comparison and exercise behaviour mediated by exercise self-identity and (2) a moderation model proposing an association between exercise behaviour and self-identity moderated by social comparison. Results of the mediation analyses revealed partial mediation of the social comparison--exercise behaviour relationship by self-identity in females. Results of the moderation analyses revealed in males a significant interaction of social comparison with exercise behaviour in the prediction of self-identity - the positive association between exercise behaviour and exercise self-identity showed only significant among male students who believed to exercise equally much or less than peers. Possible explanations and implications for exercise promotion are discussed.

Pi in the Sky

NASA Astrophysics Data System (ADS)

O'Brien, W. P.

2008-12-01

Pi In The Sky (PITS) consists of a loose collection of virtual globe (VG) activities with a slight mathematical twist, wherein students search for interesting circular structures on the surface of Earth (Moon or other planets) and measure the circumference C and diameter D of each structure, using the built-in VG measure tool, in order to determine experimental values of pi from the C/D ratios. Examples of man-made circular structures visible using VG browsers include Fermilab and l"Arc de Triomphe roundabout; quasi-circular natural structures include certain volcano calderas and impact craters. Since a circle is but a special case of an ellipse, a natural extension of the activity involves making similar measurements of perimeter P, semi-major axis a, and semi-minor axis b of a visible elliptical structure (such as one of the thousands of elliptical Carolina bays, enigmatic depressions on the Atlantic Coast of North America) and solving for pi using Ramanujan's first approximation for the dependence of the perimeter of an ellipse on a and b. PITS exercises can be adapted to a wide range of student ages and teaching goals. For instance, K-6 students could measure C and D of the huge irrigation circles near Circle, Texas, to discover pi in the same way they might infer pi from measurements of coffee-can lids in math class. Middle school and high school students could move beyond man-made circles to consider the near-circularity of certain volcano calderas and impact craters in earth science units, make measurements for Olympus Mons on Mars or Crater Kepler on the moon in astronomy units, or search for circularity among Arctic thermokarst lakes as an introduction to climate change in tundra environments in environmental science units; such studies might ignite student curiosity about planetary processes. High school students of analytic geometry could examine several elliptical Carolina bays and calculate not only values of pi (as noted above) but also determine the range of eccentricities exhibited by these structures; through these exercises, ellipses acquire significance beyond conic sections and planetary orbits. At whatever level, PITS exercises function as easy bait, enticing students to learn to operate VG software and make observations and quantitative measurements of interesting Earth features. On a deeper level, these exercises provide a context and tool enabling VG explorers to fly above Earth's surface, to see this surface megascopically as it heretofore has never been seen, and to play in the metaphorical geometric intertidal zone that resides between shallow, eyes-on-the-ground, normal perception and the deep-blue depths of the cosmos.

Smoking, diet, and physical exercise are key determinants of health. This study assessed changes over 10 years and their relationship to changes in health beliefs and risk awareness. A survey was carried out of university students from 13 European countries (Belgium, England, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, The Netherlands, Poland, Portugal, and Spain) in 1990 (4,701 men, 5,729 women) and repeated in 2000 (4,604 men, 5,732 women). We assessed smoking, exercise, fruit and fat intake, beliefs in the importance of behaviors for health, and awareness of the influence of behaviors on heart disease risk. Smoking prevalence increased and fruit consumption decreased between 1990 and 2000, while physical exercise and fat intake were more stable. There were large variations between country samples. Health beliefs weakened, with marked decreases in beliefs about smoking and diet. Across country samples, changes in beliefs correlated with changes in the prevalence of behaviors. Awareness of the effects of smoking and exercise was stable, but knowledge of the role of fat intake increased over the decade. The differences in health behaviors, beliefs, and risk awareness between the two surveys were disappointing in this educated sector of young adult Europeans. The association between changes in beliefs and prevalence of behavior emphasizes the importance of enhancing positive attitudes to healthier lifestyles.

Korn, Liat; Gonen, Ester; Shaked, Yael; Golan, Moria

2013-01-01

Purpose This study examines health perceptions, self and body image, physical exercise and nutrition among undergraduate students. Methods A structured, self-reported questionnaire was administered to more than 1500 students at a large academic institute in Israel. The study population was heterogenic in both gender and fields of academic study. Results High correlations between health perceptions, appropriate nutrition, and positive self and body image were found. The relationships between these variables differed between the subpopulation in the sample and the different genders. Engagement in physical exercise contributed to positive body image and positive health perceptions more than engagement in healthy nutrition. Nutrition students reported higher frequencies of positive health perceptions, positive self and body image and higher engagement in physical exercise in comparison to all other students in the sample. Conclusions This study suggests, as have many before, that successful health promotion policy should reflect a collectivist rather than an individualist ethos by providing health prerequisites through a public policy of health-promotion, where the academic settings support a healthy lifestyle policy, by increasing availability of a healthy, nutritious and varied menu in the cafeterias, and offering students various activities that enhance healthy eating and exercise. Implications and contribution This study examined health perceptions, self-image, physical exercise and nutrition among undergraduate students and found high correlations between these topics. Nutrition students reported higher frequencies of positive health perceptions, and positive self and body image and engaged more in physical exercise when compared with all other students in the sample.

Takahata, Yoko

2018-05-09

The purpose of this study was to determine whether or not circuit training at home affects the calcaneus quantitative ultrasound status as well as other indices of body composition among undergraduate female students. Forty-one adolescents were recruited (18.5 ± 0.6 years old). The stiffness index of the calcaneus, broadband ultrasound attenuation of the calcaneus, speed of sound of the calcaneus, and body frame index. This was a three-month intervention study, so the measurements were conducted at baseline, 2 months later, and 3 months later while the subjects underwent circuit training at home. The subjects were divided into two groups: namely, the exercising group and non-exercising group. In the exercising group, broadband ultrasound attenuation of the calcaneus was higher 2 months later (p = 0.033) as well as 3 months later (p = 0.036), and the speed of sound of the calcaneus was higher 3 months later (p = 0.018). In addition, the muscle mass was strongly positively correlated with the calcaneus QUS-SOS (p = 0.004), while the body fat percentage was a strongly negatively correlated with the calcaneus QUS-BUA (p = 0.043). In the non-exercising group, the stiffness index of the calcaneus was higher 2 months later (p = 0.002) as well as 3 months later (p = 0.002). Furthermore, the body percentage was strongly positively correlated with the calcaneus QUS-SI (p = 0.009). These findings suggest that the calcaneus quantitative ultrasound status and muscle mass while losing fat mass may be improved by means of a simple exercise regimen within a short period among undergraduate female students.

Latham, Lesley; MacDonald, Aimee; Kimball, Alexa B; Langley, Richard G

Psoriasis has a profound negative effect on quality of life that is often underappreciated by health care professionals and the public. We sought to assess the perception of the burden of psoriasis relative to other medical conditions in first-year medical students, and to determine if wearing a temporary tattoo simulating psoriasis during a teaching exercise would change their perceptions. Participants completed a questionnaire assessing their perception of the impact of psoriasis and other common medical conditions (visual analog scale). Participants then wore a temporary tattoo of a psoriatic lesion for 24 hours and completed the same questionnaire after this exercise. Of 91 students approached, 61 completed the study. At baseline, psoriasis (mean = 23.6) and eczema (mean = 23.3) were perceived as having the lowest physical burden of diseases queried (P < .0001), whereas the mental impact of psoriasis was scored comparably with arthritis, heart disease, and diabetes (mean = 45.1-56.7), but lower than cancer (mean = 82.2) and depression (mean = 93.8). After the exercise, the perception of the impact of eczema (physical: mean = 37.3, P < .0001; mental: mean = 66.6, P = .0005) and psoriasis (physical: mean = 37.8, P = .0014; mental: mean = 68.6, P = .0293) was significantly increased. The exercise did not simulate the chronic nature of psoriasis or the scaling and pruritic characteristics of psoriatic lesions. The survey instrument used to assess empathy has not been previously validated and statistical analysis was limited by small sample size and the absence of a control group. Temporary tattoos are a novel and effective method of teaching medical students about the psychological burden of psoriasis. Copyright © 2011 American Academy of Dermatology, Inc.

To investigate the prevalence of suspected myopia among students and to examine the relationship between time spent on physical exercise, sleep, homework and suspected myopia. A total of 8 030 primary and secondary school students from 4(th) to 12(th) grades were selected from the National Student Constitution and Health Survey (NSCHS) in Anhui province in 2014. Time spent on exercise, sleep and homework per day were collected using a self-administrated questionnaire. Visual acuity was examined using the Standard Logarithmic Visual Acuity Chart. The overall prevalence of suspected myopia was 69.03%. Prevalence rates of suspected myopia appeared higher in girls, in urban students, with the highest in the 16 to 18 year-old groups. RESULTS from the multiple logistic regression analysis showed that the amount of time spent on physical exercise, sleep and homework per day were all significantly associated with suspected myopia. Suspected myopia was associated with longer time on physical exercise among students aged 8 to 12 years (OR=0.80, 95%CI: 0.64-0.99), and longer sleep time among students in the age groups of 13 to 15 years and 16 to 18 years (OR=0.73, 95% CI: 0.56-0.94;OR=0.38, 95% CI: 0.21-0.68, respectively). Longer time spent on homework significantly increased the risk of suspected myopia among students in the age groups of 8 to 12 years and 13 to 15 years (OR=1.41, 95%CI: 1.11-1.79; OR=1.74, 95% CI: 1.36-2.23, respectively). Suspected myopia appeared common among students. Comprehensive intervention programs focusing on sufficient physical exercise and sleep but less homework might help to prevent myopia among students at different ages.

Mastery-style exercises in physics

NASA Astrophysics Data System (ADS)

Schroeder, Noah D.

Mastery learning employs repeated cycles of instructional support and formative assessment to help students achieve desired skills. Instructional objectives are broken into small pieces, and students master those pieces in successive order by performing to a set standard on an assessment for each objective. If a student cannot master an objective, instructional support is provided, and the student is reassessed. Mastery learning has been proved effective in many subject areas, but comparatively little research has been done on applying it in physics instruction. This dissertation details the path taken that culminated in the use of mastery-inspired exercises to teach students basic skills in introductory physics courses. The path that led to our choice of mastery began with an attempt to provide students with extra practice and formative assessment through weekly practice tests with corresponding solutions, with the goal of helping them better prepare for summative exams in an introductory physics course. No effect was seen, and participation was very low. Investigating how students learn from solutions revealed that they are poor evaluators of their understanding of provided solutions and struggle to retain the skills taught in those solutions. In a follow-up clinical experiment that provided students with solutions, required them to recall the solutions from memory, and re-presented the solutions for restudy, students showed strong retention as well as the ability to transfer information from the solutions to new situations. These results inspired the formal use of mastery learning as an instructional paradigm due to its requirement that students repeatedly recall information from solutions and apply it to new situations. Mastery-style exercises were first created and tested in clinical trials, followed by two in-course implementations. In the clinical trials, students completed a set of questions on a particular skill, and if they failed to master that skill, they were given support in the form of narrated animated solution videos followed by a new version of the question set. On mastering a skill, students moved on to the next skill level. Students mastered all provided skill levels and then took a post-test. Those clinical trials demonstrated that students can use provided solutions to quickly progress through successive levels of mastery exercises and that mastery-style exercises had a larger impact on the post-test than traditional multi-try immediate feedback homework exercises. Following these strong results, mastery-style exercises were implemented over an entire semester in an introductory course, replacing the existing homework. Participation was much poorer than in the clinical experiments due to frustration with the difficulty of the provided exercises. As a result the implementation had a comparatively small impact on student performance. Frustrated students circumvented the system by ignoring provided solutions and skipping assessments, choosing instead to cycle through the provided versions until they could reattempt an already seen version of an assessment. A follow-up implementation covering a single week had a larger impact on a quiz, yet students were still frustrated with the exercises and displayed behaviors similar to those seen in the semester-long implementation. Moving forward, frustration must be overcome to return participation to levels seen in the clinical trials. A preliminary development mode is suggested to ensure proper calibration of difficulty to student skills. Other changes involving how the mechanics of the system work as well as how its benefits are communicated to students are also suggested. If frustration is overcome and participation increases, the incredible potential of mastery-inspired exercises can be realized. Mastery is a powerful addition to physics instruction.

2008-01-01

Objectives To implement didactic and problem-based learning curricular innovations aimed at increasing students' knowledge of Medicare Part D, improving their ability to apply the online Medicare Prescription Drug Plan Finder tool to a patient case, and improving their attitudes toward patient advocacy for Medicare beneficiaries. Methods A survey instrument and a case-based online Medicare Prescription Drug Plan Finder tool exercise were administered to a single group (n = 120) of second-year pharmacy graduate students prior to and following completion of a course on health policy. Three domains (knowledge, skill mastery and attitudes) were measured before and after two 90-minute lectures on Medicare Part D. Results The online Medicare Prescription Drug Plan Finder exercise and Medicare Part D didactic lectures had positive effects on students' knowledge of Part D, attitudes toward patient advocacy, and ability to accurately use the Medicare Prescription Drug Plan Finder tool. Conclusions The success of these didactic and problem-based curricular innovations in improving pharmacy students' knowledge, skills, and attitudes regarding Part D warrants further evaluation to determine their portability to clinical settings and other pharmacy schools.

Teaching Resistance through an interactive gaming lab

O'Brien, James G.; Sirokman, Greg; Rueckert, Franz; Cascio, Derek

2015-04-01

The use of gaming as an educational tool has proven to be an effective paradigm in modern pedagogy. Following the success of their previous work ``Sector Vector,'' the authors present a new interactive game-based laboratory to highlight the basic manipulation and calculation of resistors in circuits. ``Resistance is Futile'' delivers the lesson of basic resistor combinations in a game based exercise where teams build a continually evolving circuit. As the game progresses, students must develop long and short term plans to modify an ever-changing circuit and meet primary and secondary objectives. Each turn requires quick calculations of resistor combinations and the assessment of future options. Students are also exposed to the creation of a modular circuit, which may not conform to standard textbook examples. To determine a winner, the students work together to analyze and evaluate a potentially complex final circuit diagram. The dynamic atmosphere and competitive nature established by the gaming environment have been shown to increase student engagement and concept retention. In this presentation, we will discuss both the structure of the lab-based game and the pedagogical implications this implementation versus the traditional resistor combination laboratory exercise.

Predictors of exercise relapse in a college population.

PubMed

Sullum, J; Clark, M M; King, T K

2000-01-01

Exercise improves physical and mental health. Nevertheless, most 20-year-olds do not exercise, and approximately 50% of the participants in exercise programs drop out in the first 3 to 6 months. In view of the health benefits of exercise, college health educators and clinicians need to be able to identify factors that predict exercise relapse in a student population. The authors administered questionnaires measuring Prochaska's 10 processes of change for exercise, self-efficacy, and decisional balance to 52 physically active undergraduate students. They assessed baseline exercise levels in October and reassessed them about 8 weeks later. At baseline, relapsers had significantly lower self-efficacy scores than those who maintained their exercise levels. The relapsers also had higher perceived negative views of exercise. These findings provide support for applying the transtheoretical model of behavioral change to a college population.

Personal motivation, exercise, and smoking behaviors among young adults.

Scioli, Erica Rose; Biller, Henry; Rossi, Joseph; Riebe, Deborah

2009-01-01

This study explored the motivational factors that influence individuals across the stages of change for exercise. The authors compared physically active nonsmokers with physically active smokers in a college student population. Half of regular exercisers identified themselves as smokers. Compared with their nonsmoking peers, young smokers have higher rates of physical and emotional distress. Those participants who exercise and do not smoke are more likely to exhibit intrinsic factors for exercise. Undergraduate psychology students (N = 614) completed an Internet survey on exercise and smoking behavior as well as motivational factors for exercise. Multivariate analyses of variance revealed that intrinsic motivational factors for exercise were significantly higher for the active nonsmokers than for the active smokers. Interventions promoting consistent exercise and smoking abstinence should continue to be directed toward young adults, focusing on fostering intrinsic motivational factors for exercise.

Contributions of psychological needs, self-compassion, leisure-time exercise, and achievement goals to academic engagement and exhaustion in Canadian medical students.

Babenko, Oksana; Mosewich, Amber; Abraham, Joseph; Lai, Hollis

2018-01-01

To investigate the contributions of psychological needs (autonomy, competence, and relatedness) and coping strategies (self-compassion, leisure-time exercise, and achievement goals) to engagement and exhaustion in Canadian medical students. This was an observational study. Two hundred undergraduate medical students participated in the study: 60.4% were female, 95.4% were 20-29 years old, and 23.0% were in year 1, 30.0% in year 2, 21.0% in year 3, and 26.0% in year 4. Students completed an online survey with measures of engagement and exhaustion from the Oldenburg Burnout Inventory-student version; autonomy, competence, and relatedness from the Basic Psychological Needs Scale; self-compassion from the Self-Compassion Scale-short form; leisure-time exercise from the Godin Leisure-Time Exercise Questionnaire; and mastery approach, mastery avoidance, performance approach, and performance avoidance goals from the Achievement Goals Instrument. Descriptive and inferential analyses were performed. The need for competence was the strongest predictor of student engagement (β= 0.35, P= 0.000) and exhaustion (β= -0.33, P= 0.000). Students who endorsed mastery approach goals (β= 0.21, P= 0.005) and who were more self-compassionate (β= 0.13, P= 0.050) reported greater engagement with their medical studies. Students who were less self-compassionate (β= -0.32, P= 0.000), who exercised less (β= -0.12, P= 0.044), and who endorsed mastery avoidance goals (β= 0.22, P= 0.003) reported greater exhaustion from their studies. Students' gender (β= 0.18, P= 0.005) and year in medical school (β= -0.18, P= 0.004) were related to engagement, but not to exhaustion. Supporting students' need for competence and raising students' awareness of self-compassion, leisure-time exercise, and mastery approach goals may help protect students from burnout-related exhaustion and enhance their engagement with their medical school studies.

The Molecular Modeling Workbook for Organic Chemistry (by Warren J. Hehre, Alan J. Shusterman, and Janet E. Nelson)

NASA Astrophysics Data System (ADS)

Crouch, R. David

1999-09-01

Wavefunction, Inc.: Irvine, CA, 1998. 307 pp. ISBN 1-890661-06-6. 30.00. This workbook is the latest in a series of "lab manuals" designed to increase the presence of molecular modeling and computational chemistry in undergraduate courses. The authors have designed the workbook to differ from its predecessors in two ways: the target audience is introductory organic chemistry students, and a CD-ROM containing files of molecules and data replaces the need for expensive molecular modeling software. It also differs from its predecessors in that the exercises in it are not really molecular modeling experiments. Instead, students are introduced to the field by viewing the results of computational work stored on the CD-ROM. The workbook is divided into 21 chapters, each of which covers a topic encountered in introductory-level organic chemistry. The sequence of chapters follows the sequence of topics that instructors of introductory organic courses might employ, allowing the workbook to be used with most modern organic chemistry texts. The heart of the workbook, though, is the CD-ROM included with the book. It contains files of molecules and their accompanying computational results as well as Spartan View, a software package that allows these models to be visualized. Although it does not allow actual calculations to be performed, Spartan View permits the user to rotate molecules, intermediates, and transition states and retrieve "precalculated" values of bond and dihedral angles, bond lengths, energies, dipole moments, charge, and frequency of vibration. Spartan View also allows the user to search molecules and intermediates for electron-rich or electron-poor regions by showing electrostatic potential as well as HOMOs and LUMOs. Some files allow for animation of reactions or conformational changes. Note, however, that since the data are just stored on the CD-ROM, not all the data are available for all files. Although performing calculations is not an option, Spartan View can be used to display models and data obtained using Spartan or MacSpartan and stored on a disk. In this way, student exercises can be customized by the instructor or the instructor can prepare customized examples for use in lecture. Each chapter in the workbook contains a series of 3 to 17 exercises that use models and associated data contained on the accompanying CD-ROM. The exercises are not simply cookbook procedures in which the student is directed how to solve a problem. Instead, the authors provide background in a two-part tutorial and several essays that describe the information that can be obtained through molecular modeling, and then introduce a problem in organic chemistry that can be addressed using molecular modeling. The student is left to determine how best to obtain the requested data. For example, an exercise in the chapter Acids & Bases directs the student to determine the atomic charges and view the electrostatic potential map of the conjugate bases of three organic acids. The student is not, however, told which menu to pull or button to push. At the end of the exercise, the student is directed to compare the reactivity of the acids with the data collected from Spartan View. The exercises are relatively easy to complete after spending a few minutes with the tutorials, and many require students to compare the results of calculations with the reactivity of the molecules as discussed in the traditional lecture portion of the course. In this sense, the workbook provides a meaningful link between molecular modeling exercises outside of class and activities in the classroom. While some exercises involve comparing the energies of intermediates or transition states, others are more like videos of processes. Instructors will find many of these to be useful as visual aids in lecture. Mechanisms of Ring Inversion, for example, allows the instructor to show the stepwise ring flip of cyclohexane. Although some of the animations are very similar to those contained on CD-ROMs that sometimes accompany textbooks, the exercises in this workbook allow for the retrieval of data such as the energies of the various conformations cyclohexane. Not only can the student see the stepwise conversion of one chair conformation into another, but the changes in energy as the ring flip occurs are available. Also, unlike many of the visualizations on the CD-ROMs packaged with textbooks, these give the student control over the orientation of the structures on the screen, allowing views from numerous angles. The possibility of the instructor's customizing the exercises adds to the appeal of this workbook. In reviewing this book, I noted a couple of problems. The energy of molecules is presented in hartrees or atomic units (au). Although a factor is given for converting these values into the more familiar kcal/mol or kJ/mol, wouldn't it be easier to use these results if they were given in the units that are more typically used in introductory organic chemistry texts? Similarly, a number of exercises ask the student to plot data that they have calculated in the exercise. However, no routine for plotting the data is included with Spartan View and students must go through the cumbersome process of copying the values and preparing the plots using another program or by hand. And, finally, in Tutorial B, animations are introduced by showing "the SN2 displacement of chloride in tert-butyl chloride by bromide." Although the animation shows an SN1 mechanism with the C-Cl bond breaking before approach of the incoming bromide ion, students who are new to organic mechanisms will be misled by the erroneous description in the workbook. Although instructors may want to carefully consider whether to add an additional 30 to the already high cost of required texts, this workbook provides a unique and potentially valuable addition to the introductory organic chemistry course. With many exercises involving the visualization of electrostatic potentials and HOMOs and LUMOs, it adds an increased presence of physical organic chemistry in the introductory course. And, although the exercises are not really molecular modeling, this workbook also provides a low-cost introduction to the field without the considerable cost of modeling software. If Spartan or MacSpartan is already available in the department, the possible tie-in with the workbook and the capability to project the results should make this an attractive addition to any instructor's repertoire of visualization tools for lecture. The Molecular Modeling Workbook for Organic Chemistry is definitely worthy of consideration by anyone interested in adding molecular modeling to the organic course.

Aggregated effects of combining daily milk consumption and aerobic exercise on short-term memory and sustained attention among female students.

PubMed

Leong, In-Tyng; Moghadam, Sedigheh; Hashim, Hairul A

2015-02-01

Regular aerobic exercise and milk consumption have been found to have positive effects on certain cognitive functions such as short-term memory and sustained attention. However, aggregated effects of combining these modalities have not been explored. This study examined the combined effects of milk supplementation and aerobic exercise on the short-term memory and sustained attention of female students aged 16 yr. (N = 81). The intervention involved serving of 250 ml of regular milk during school days and/or a 1-hr. aerobic exercise period twice per week for 6 weeks. The Digit Span Test and Digit Vigilance Test were used to measure short-term memory and sustained attention, respectively. The combination group (milk and exercise) and exercise group performed significantly better than did the milk and control groups in terms of short-term memory. No significant interaction or group differences were found for sustained attention. The results suggest benefits of regular exercise for students' short-term memory.

Use of Feedback-Oriented Online Exercises to Help Physiology Students Construct Well-Organized Answers to Short-Answer Questions

PubMed Central

Carnegie, Jacqueline

2015-01-01

Postsecondary education often requires students to use higher-order cognitive skills (HOCS) such as analysis, evaluation, and creation as they assess situations and apply what they have learned during lecture to the formulation of solutions. Summative assessment of these abilities is often accomplished using short-answer questions (SAQs). Quandary was used to create feedback-oriented interactive online exercises to help students strengthen certain HOCS as they actively constructed answers to questions concerning the regulation of 1) metabolic rate, 2) blood sugar, 3) erythropoiesis, and 4) stroke volume. Each exercise began with a SAQ presenting an endocrine dysfunction or a physiological challenge; students were prompted to answer between six and eight multiple-choice questions while building their answer to the SAQ. Student outcomes on the SAQ sections of summative exams were compared before and after the introduction of the online tool and also between subgroups of students within the posttool-introduction population who demonstrated different levels of participation in the online exercises. While overall SAQ outcomes were not different before and after the introduction of the online exercises, once the SAQ tool had become available, those students who chose to use it had improved SAQ outcomes compared with those who did not.

Getting Real: A General Chemistry Laboratory Program Focusing on "Real World" Substances

NASA Astrophysics Data System (ADS)

Kerber, Robert C.; Akhtar, Mohammad J.

1996-11-01

In order to confront the abstractness of the freshman chemistry syllabus and the consequent failure of students to relate what they learn to their everyday lives, we have designed a new freshman laboratory program. It is intended as an interface between the substances that surround the students in their ordinary lives and the abstract principles presented in chemistry classrooms (1). A laboratory should provide the organized experiences and observations that underlie the intellectual constructs of chemistry, and tying these experiences and observations to the real world can help to provide motivation for study of the principles. The freshman laboratory program constitutes the foundation for subsequent laboratory courses. However, the good habits we strive to develop there (careful observation, thorough record keeping, proper use of equipment, objective data analysis) are essential to all scientific work, and are intended to provide lasting educational value for all students, especially those who do not take later laboratory work. What We Do A list of the laboratory exercises carried out during 1994-1995 is presented in Table 1. The course incorporates the following features. 1. The exercises deal with recognizable, everyday substances, not just with "chemicals". That "baking soda" and "sodium bicarbonate" are the same is a chemical truism of which the students may be aware, but the visible presence of the Arm and Hammer box nevertheless helps them to make connections to the world outside the laboratory. Perceiving the connections, students may be inspired by curiosity to understand chemical phenomena better, not just to tolerate what they are being taught, as an irrelevant hurdle in the pursuit of a career. 2. Since many significant substances around students in the everyday world are organic, we work in the lab with organic as well as the usual inorganic materials. These include analgesics, vitamins, antifreeze, foodstuffs, dyestuffs, plastics, and fibers. In working with these materials, we present chemical structures wherever possible, but do not emphasize organic nomenclature or functional group chemistry beyond identifying, as appropriate, acidic and basic groups and other key structural features. 3. As can be appreciated from Table 1, the course organization is overtly based on the nature of the materials themselveshousehold "chemicals", food and beverages, pills, and plasticsrather than on abstract chemical principles. Organizing the course on the basis of the materials studied emphasizes their relevance to students and focuses interest on the actual results obtained by the individual students. Nevertheless, a coherent sequence of development of laboratory techniques and gradually increasing opportunity for less tightly directed student experiences is maintained. Laboratory exercises cover most of the usual topics, including stoichiometry, qualitative analysis, quantitative analyses by acid-base and redox titrations, and colorimetry. We have not, however, found or devised exercises dealing with thermochemistry or electrochemistry; readers' suggestions in these areas would be welcome. 4. The instruments, equipment, and techniques used in the laboratory initially were the same as previously used, so that we have been able to introduce this program without initial capital expenditure. The exercises rely substantially upon mass measurements and titrations, with pH meters and colorimeters brought into use as the year progresses. We are now in the process of introducing Fourier transform infrared (FTIR) methods into the laboratories. This will add a very powerful tool to the students' repertoire. Its use will greatly expand the opportunities for directed-inquiry investigations of real-world samples in the context of the course. 5. Some of the exercises in Table 1 will be recognized by readers of this Journal as standard ones, found in many lab manuals or available as commercial modules (2). To provide a comprehensive focus on "real world" substances, however, we have also devised some new laboratory exercises or adapted existing ones. Sources are cited in Table 1 and in the references; in most cases, published exercises have been extended and modified to fit our theme. Some general descriptions of the more novel exercises appear below. We will be pleased to provide details on any of the exercises to interested readers. 6. To further emphasize the quotidian nature of the samples under study, we have encouraged students to bring their own samples to the laboratory by offering a small number of bonus points (up to 5% of the total points awarded in the course). Student participation has been very gratifying, with two-thirds of the students, on average, bringing in designated materials (indicated in Table 1). Although our primary purpose in encouraging "bring your own" is pedagogical, we are not unaware of a favorable effect on the course budget. 7. Fill-in-the-blank report forms are used to guide calculations in the quantitative exercises, helping to assure reliable conversion of measurements into meaningful results that allow comparison of various student samples. In the more qualitative exercises, however, we emphasize use of the laboratory notebook for record-keeping (3). As an incentive for development of good notebook habits, students are allowed to use their laboratory notebooks on lab quizzes, and the notebooks themselves are graded for thoroughness and accuracy at least once each semester. 8. Most laboratory exercises are conducted on an S/U basis. Numerically graded exercises, indicated in Table 1, are performed only after students have gained experience in basic operations by working on S/U exercises. Some Features of the More Novel Exercises 1. In "Identification of Household `Chemicals' ", each student is given a white powder and a list of some twenty such powders that might be found in or around an American household. They perform some simple solubility and reactivity tests and compare results with their classmates by use of a flip chart on which the results are summarized. Their purpose the first week is to identify one or two classmates who share the same sample. The second week, authentic samples are provided, and the teams identify their common unknown by comparison of its properties with the knowns. We encourage final comparison to be on a quantitative basis. 2. In "Properties of Antifreeze-Water Mixtures", each student is assigned a weight percent and prepares a mixture of ethylene glycol and water of that composition. He or she then measures its initial boiling point, density, and viscosity (falling ball method). The class data are entered into spreadsheets and printouts of all class data are provided before the students leave. The second week, they are given an unknown mixture and determine its composition by whatever measurements they choose to use, in comparison with the aggregated class data. Despite large scatter in the class data, 80% of the students identify the unknown composition to within 5%. 3. In the three-week group of exercises dealing with aspirin, students synthesize a sample of aspirin the first week by a standard method. During the next two weeks, they analyze their product and commercial samples by two different methods, which allows comparison of convenience and reliability of the two methods as well as comparison of the samples themselves. Similarly, two complementary methods are used in determining calcium in antacids later on. 4. In "Identification of Plastics", plastic packaging materials, identified initially by their recycling codes, are characterized according to density, solubility, and responses to heating. The behavioral profiles are then used to identify unknown plastic samples. 5. Similarly, in "Textiles and Dyeing", samples of six common fibers, both natural and human-made, are subjected to a battery of tests involving elemental composition, chemical behavior, solubility in organic solvents, and response to dyeing. Identification of unknowns is then possible by comparison with the knowns. Student success in identifying both the plastics and the fibers is increased by willingness to do side-by-side comparison of knowns and unknowns and by careful observation of responses. Accuracy of identification in each case is 80-90%. Student Evaluations Student response to the new laboratory program has generally been positive. On a scale of 4.0 (very favorable) to 0.0 (very unfavorable), responses are favorable to working in groups of two or three (3.30) and to bringing in samples (3.05). They were nearly neutral (2.24) to working with pooled section data, as in the antifreeze exercise. The exercises found most interesting by students were synthesis of polymers (3.08), paper chromatography of food dyes (3.04), textiles and dyeing (2.96), and determination of zinc on galvanized nails (2.95). Found least interesting were the unknown acid (2.08), determination of aspirin purity by colorimetry (2.13) and pH titration (2.28), and vinegar titration (2.42). These less popular exercises tended to be graded exercises and exercises requiring more extensive calculations. Student assessments of educational quality closely tracked their assessments of how interesting they found the exercises. Overall, student course evaluations, as conducted by anonymous university questionnaires, improved by 0.5 to 0.7 units (on a 7-unit scale) in the category "I would strongly recommend this [course] to a friend," and by 0.4 to 0.6 units in the category, "I have learned morethan from othercoursesof similar size and level." Further Development We have begun to introduce FTIR methods into the laboratory program. These will be used initially to assist in identification of household "chemicals" and the unknown acid, and to investigate internal combustion engine exhaust gasses. They will be applied to qualitative analysis of aspirin, vitamin C samples, and plastic samples. We hope to introduce an open-ended exercise on comparison of synthetic and "organic" vitamin C using student-initiated means, including infrared analysis and acid-base and redox titrations. Acknowledgments We gratefully acknowledge the participation of our colleague Robert Schneider in the implementation of this program. Expansion of the program through incorporation of infrared has been made possible by support of the National Science Foundation's Division of Undergraduate Education through grant DUE-9552250, which we also acknowledge with gratitude.

Egli, Trevor; Bland, Helen W; Melton, Bridget F; Czech, Daniel R

2011-01-01

The authors examined differences in exercise motivation between age, sex, and race for college students. Students from 156 sections of physical activity classes at a midsize university were recruited (n = 2,199; 1,081 men, 1,118 women) in 2005-2006 and volunteered to complete the Exercise Motivation Inventory. Quantitative, cross-sectional descriptive research design was employed. Significant differences were found in 3 of 14 exercise motivational subscales by age (affiliation, health pressures, and ill health avoidance) (p < .05). Males were motivated by intrinsic factors (strength, competition, and challenge) (p < .05) and females by extrinsic factors (ie, weight management and appearance) (p < .05); only 2 subscales proved not to be significant by sex. Race differences provided 8 significant differences by exercise motivations (p < .05). Significant differences for exercise motivations in college-aged population by demographics were documented. Understanding these differences is important for college health professionals for programming strategies and promoting physical activity.

Golick, Douglas A.; Heng-Moss, Tiffany M.; Steckelberg, Allen L.; Brooks, David. W.; Higley, Leon G.; Fowler, David

2013-08-01

The purpose of the study was to determine whether undergraduate students receiving web-based instruction based on traditional, key character, or classification instruction differed in their performance of insect identification tasks. All groups showed a significant improvement in insect identifications on pre- and post-two-dimensional picture specimen quizzes. The study also determined student performance on insect identification tasks was not as good as for family-level identification as compared to broader insect orders and arthropod classification identification tasks. Finally, students erred significantly more by misidentification than misspelling specimen names on prepared specimen quizzes. Results of this study support that short web-based insect identification exercises can improve insect identification performance. Also included is a discussion of how these results can be used in teaching and future research on biological identification.

Symptoms of exercise dependence and physical activity in students.

PubMed

MacLaren, Vance V; Best, Lisa A

2007-12-01

Health professionals recognize the benefits of moderate physical activity and encourage clients to engage in some form of activity on a regular basis. In spite of these recognized benefits, there are growing concerns that some may exercise at levels detrimental to health. The term exercise dependence refers to those individuals whose extreme exercise schedules interfere with their social, occupational, and family lives. The purpose of this study was to examine the relationship between weekly exercise habits and scores on the Exercise Dependence Questionnaire in a sample of undergraduate students (213 women and 79 men). Overall, participants who reported high activity scored higher than those reporting low activity on subscales measuring interference with family and social life, positive reward, withdrawal, exercise for social reasons, exercise for health reasons, and stereotyped behavior.

Integrating PCR theory and bioinformatics into a research-oriented primer design exercise.

PubMed

Robertson, Amber L; Phillips, Allison R

2008-01-01

Polymerase chain reaction (PCR) is a conceptually difficult technique that embodies many fundamental biological processes. Traditionally, students have struggled to analyze PCR results due to an incomplete understanding of the biological concepts (theory) of DNA replication and strand complementarity. Here we describe the design of a novel research-oriented exercise that prepares students to design DNA primers for PCR. Our exercise design includes broad and specific learning goals and assessments of student performance and perceptions. We developed this interactive Primer Design Exercise using the principles of scientific teaching to enhance student understanding of the theory behind PCR and provide practice in designing PCR primers to amplify DNA. In the end, the students were more poised to troubleshoot problems that arose in real experiments using PCR. In addition, students had the opportunity to utilize several bioinformatics tools to gain an increased understanding of primer quality, directionality, and specificity. In the course of this study many misconceptions about DNA replication during PCR and the need for primer specificity were identified and addressed. Students were receptive to the new materials and the majority achieved the learning goals.

To develop, implement, and evaluate active-learning exercises requiring the integration and application of pathophysiology, medicinal chemistry, pharmacology, and therapeutics knowledge of osteoarthritis and rheumatoid arthritis to formulate therapeutic recommendations for patients with musculoskeletal disorders. Two team-based case study exercises, one evaluating a patient with osteoarthritis and the second, a patient with rheumatoid arthritis, were developed, incorporating material and questions from pathophysiology, medicinal chemistry, pharmacology, and therapeutics. The learning assignments were implemented in a required pharmacotherapy module. Student learning was evaluated using performance on the team-based case study exercises and on 2 examinations. A standard student course evaluation was used to assess students' impressions of the learning activity. The mean student grades for the osteoarthritis and rheumatoid arthritis activities were 9.1 and 8.9, respectively, on a 10-point scale. The majority of students indicated that the learning exercises were more than adequate to excellent in helping students learn. The addition of active-learning activities was successful in teaching pharmacy students the knowledge needed to formulate therapeutic recommendations for patients with musculoskeletal disorders.

The impact of exercise performance dissatisfaction and physical exercise on symptoms of depression among college students: a gender comparison.

PubMed

Edman, Jeanne L; Lynch, Wesley C; Yates, Alayne

2014-01-01

Depression is a common psychological problem and females have been found to be at greater risk for this disorder than males. Although numerous studies have found that physical exercise is negatively associated with risk of depression, some studies suggest that negative exercise attitudes may increase the risk of depression. The present study used the survey method to examine the relationship between depressive symptoms, exercise performance dissatisfaction, body dissatisfaction, and physical exercise among a sample of 895 undergraduate university students. Females reported higher depression and exercise performance dissatisfaction scores than males; however, there were no gender differences in body dissatisfaction. Exercise performance dissatisfaction was positively associated with depression among both males and females. Physical exercise was negatively associated with depression among males, but not among females. The possibility of screening participants enrolled in exercise programs for performance dissatisfaction is discussed as negative exercise attitudes may diminish the positive impact of exercise on depressed mood.

2016-09-01

Exercise training has proven to be beneficial in the prevention of disease. In addition, exercise can improve the pathogenesis and symptoms associated with a variety of chronic disease states and can attenuate drug-induced adverse effects. Exercise is a drug-free polypill. Because the benefits of exercise are clear and profound, Exercise is Medicine, a joint initiative between the American Medical Association and American College of Sports Medicine, was launched in 2007 to call on all health care providers to counsel patients and prescribe exercise in the prevention and treatment of chronic disease states. Pharmacists play an increasing role in direct patient care and are the most accessible health care providers in the community. Thus, pharmacists should be knowledgeable in counseling patients on the frequency, intensity, time, and type of exercise that is appropriate for various conditions and disease states. The aim of the present study was to determine the prevalence of didactic course offerings in United States pharmacy school curricula regarding training in exercise prescription. School websites were accessed for information regarding course offerings in PharmD programs. No United States pharmacy schools offered courses that were dedicted to the role of exercise in disease prevention or exercise prescription in disease management. Ninety percent of pharmacy schools did not offer courses with the keywords "exercise," "fitness, or "physical activity" in the title or description. The data suggest that student pharmacists are not adequately trained to counsel patients on the benefits of exercise or exercise prescription. Copyright © 2016 The American Physiological Society.

PEARSON, REGIS C.; CRANDALL, K. JASON; DISPENNETTE, KATHRYN; MAPLES, JILL M.

2017-01-01

Applied research experiences can provide numerous benefits to undergraduate students, however few studies have assessed the perceptions of Exercise Science (EXS) students to an applied research experience. The purpose of this study was two-fold: 1) to describe the rationale and implementation of an applied research experience into an EXS curriculum and 2) to evaluate EXS undergraduate students’ perceptions of an applied research experience. An EXS measurement course was chosen for implementation of an applied research experience. The applied research experience required groups of students to design, implement, and evaluate a student-led research project. Fourteen questions were constructed, tailored to EXS undergraduate students, to assess students’ perceptions of the experience. Qualitative analysis was used for all applicable data, with repeated trends noted; quantitative data were collapsed to determine frequencies. There was an overall positive student perception of the experience and 85.7% of students agreed an applied research experience should be continued. 84.7% of students perceived the experience as educationally enriching, while 92.8% reported the experience was academically challenging. This experience allowed students to develop comprehensive solutions to problems that arose throughout the semester; while facilitating communication, collaboration, and problem solving. Students believed research experiences were beneficial, but could be time consuming when paired with other responsibilities. Results suggest an applied research experience has the potential to help further the development of EXS undergraduate students. Understanding student perceptions of an applied research experience may prove useful to faculty interested in engaging students in the research process. PMID:29170695

Perry, G A; Smith, M F

2004-05-01

Students in Reproductive Management (a senior-level course with approximately 20 to 50 students per semester) at the University of Missouri-Columbia are required to participate in a simulation exercise that is designed to improve reproductive efficiency in a beef herd. During a simulated 5-yr period, students must 1) improve reproductive efficiency in a beef cow-herd through implementation of reproductive management principles; 2) determine the economic impact of reproductive management decisions in a beef herd; and 3) evaluate the constraints of different geographical locations on approaches to reproductive management. Groups of three to four students are provided with the reproductive and economic records of a farm/ranch located in different parts of North America. Students create reproductive management plans consisting of 1) detailed discussion of farm/ranch environment (climate, terrain, forage and grain availability, and stocking rate; season for breeding and calving; and justification for choice of breed); 2) assessment of current level of reproductive performance; 3) identification and economic justification of specific (measurable) objectives; 4) discussion of alternatives for accomplishing specific objectives; 5) prediction of reproductive performance (pregnancy rate, quantity of calf weaned per cow exposed, and cost per quantity of calf weaned) in response to implementation of specific management practices; and 6) an annual and 5-yr reproductive and economic summary. Students obtain livestock marketing information for their assigned location via the Internet. Spreadsheets were developed to calculate the reproductive efficiency of postpartum cows and replacement heifers based on management decisions made by the groups and to calculate a yearly economic summary for each of the 5 yr. Management decisions are justified in a written report, and oral presentations are given to the class when the project is completed. Greater than 85% of students indicated that the exercise increased their understanding of how management decisions affect reproductive efficiency and profitability in a beef operation and also provided added confidence for students that applied for beef management positions.

The aim of the paper was to get to know, collect and present information provided by students about classes from orthodontic and their opinion regarding the conduction of clinical and theoretical exercises. The study group was comprised of 69 fifth year students from the Department of Orthodontics of the Pomeranian Medical University. The material was collected by the use of an anonymous questionnaire distributed after the final exam from orthodontics. The questionnaire was created for the study and contained 6 questions. Most of the students have admitted that knowledge gained during the 4th year was useful on the 5th year and that the information presented on orthodontic seminars during the 5th year was beneficial in regard to clinical exercises. Graduates have admitted that they felt well prepared in the field of orthodontic profilaxis and removable appliances but not enough prepared in the field of fixed appliances, retention and the repair of damaged appliances. The number of patients on clinical exercises in most answers was rated as "enough". Most of the students have answered that the way of the exercises have been conducted in their groups was acceptable and the time on exercises has been properly used. Laboratory exercises and seminars on the 4th and 5th year of studies have supplemented the knowledge of students and prepared them for clinical work in orthodontics. Students have proved to be good observers when indicating the weak points of didactics.

Blended learning (BL) is the integration of classroom learning with an online environment. The purpose of this study was to determine whether dental students who experienced BL in a preclinical endodontic course demonstrated better manual skills, conceptual knowledge, and learning experience compared to those experiencing traditional learning. All eighty-one students (100 percent) in a preclinical endodontics course agreed to participate and were assigned to either the traditional or BL group. A root canal procedure was used to determine the level of manual skills gained by each group. Pre- and post-intervention quizzes were given to all students to evaluate conceptual knowledge gained, and the students' perspectives on the methods were evaluated with a survey. The BL group scored better than the traditional group on the manual skills exercise at a statistically significant level (p=0.0067). There were no differences in the post-intervention quiz scores between the two groups, and the students' opinions were positive regarding BL. With BL, the students were able to learn and demonstrate dental skills at a high level.

Thirty patients diagnosed with non-specific LBP participated with age group between 20-50 years and divided in to 2 groups, one with core stabilization exercises and other conventional exercises, 15 subjects each. Three months study, pre and post treatment outcome measures used were VAS for pain intensity and Modified Oswestry Low Back Pain Disability Index for functional status (disability). Data were analyzed using student 't' test (paired and unpaired). Whereas both groups improved significantly from the initiation of treatment, a between-group comparison revealed significantly greater (p<0.001) improvements regarding pain and functional status for experimental group compared to control group. Core stabilization exercises were found to be more effective in reducing pain and improving functional status by decreasing disability of patients with non-specific low back pain in comparison with conventional exercises.

The Math You Need at Trinity College, Hartford CT

NASA Astrophysics Data System (ADS)

Geiss, C. E.

2011-12-01

Trinity College is a small, private, highly selective liberal arts college with approximately 2400 students. Most students have relatively well developed quantitative skills, but many are nevertheless insecure about their abilities and reluctant to engage in courses that stress quantitative content. I have used The Math You Need (TMYN) modules in an introductory geology course which serves both majors and non-majors in Trinity's Environmental Science Program. This dual audience makes the introduction of quantitative exercises labor intensive and challenging for both students and instructor. TMYN was introduced to a) offer the students an independent support structure outside of class and to b) free up some class and office hour time that would have been spent on mathematical background information. THMY was added to the course as a set of homework assignments preceding related laboratory exercises and homework assignments. During the semester most feedback regarding TMYN was negative. Some outspoken students either saw it as additional busywork or generally disliked "being taught by a computer". A review of pre- and post-test data, however, revealed that the exercises improved students' quantitative skills. Furthermore, in the assignments most students ranked the exercises as useful and rewarding. These positive results were relatively independent of student skill levels.

Partial polarization: a comprehensive student exercise

NASA Astrophysics Data System (ADS)

Topasna, Gregory A.; Topasna, Daniela M.

2015-10-01

We present a comprehensive student exercise in partial polarization. Students are first introduced to the concept of partial polarization using Fresnel Equations. Next, MATHCAD is used to compute and graph the reflectance for dielectrics materials. The students then design and construct a simple, easy to use collimated light source for their experiment, which is performed on an optical breadboard using optical components typically found in an optics lab above the introductory level. The students obtain reflection data that is compared with their model by a nonlinear least square fit using EXCEL. Sources of error and uncertainty are discussed and students present a final written report. In this one exercise students learn how an experiment is constructed "from the ground up". They gain practical experience on data modeling and analysis, working with optical equipment, machining and construction, and preparing a final presentation.

Manual and computer-aided materials selection for industrial production: An exercise in decision making

NASA Technical Reports Server (NTRS)

Bates, Seth P.

1990-01-01

Students are introduced to methods and concepts for systematic selection and evaluation of materials which are to be used to manufacture specific products in industry. For this laboratory exercise, students are asked to work in groups to identify and describe a product, then to proceed through the process to select a list of three candidates to make the item from. The exercise draws on knowledge of mechanical, physical, and chemical properties, common materials test techniques, and resource management skills in finding and assessing property data. A very important part of the exercise is the students' introduction to decision making algorithms, and learning how to apply them to a complex decision making process.

2018-01-01

The purpose of this study was to examine the determinants of benefits and barriers and their relationship with physical activity (PA) among predominantly Latino middle school students. Data were collected in a cross-sectional survey of 4,773 seventh-grade students recruited from a large, urban school district in Los Angeles. Hierarchical logistic regression models were used to assess determinants of benefits and barriers as well as their association with self-reported PA. Differences in benefits and barriers were observed by gender, ethnicity, and body size. Barriers were negatively correlated with all three PA outcomes while benefits were positively associated with exercising at least 60 min daily. A deeper understanding of benefits and barriers can facilitate the development of interventions and collaborative efforts among physical education teachers, school nurses, and administrators to implement comprehensive approaches that encourage students' participation in PA inside and outside of the classroom.

2012-03-12

To introduce a multiple-instructor, team-based, active-learning exercise to promote the integration of basic sciences (pathophysiology, pharmacology, and medicinal chemistry) and clinical sciences in a doctor of pharmacy curriculum. A team-based learning activity that involved pre-class reading assignments, individual-and team-answered multiple-choice questions, and evaluation and discussion of a clinical case, was designed, implemented, and moderated by 3 faculty members from the pharmaceutical sciences and pharmacy practice departments. Student performance was assessed using a multiple-choice examination, an individual readiness assurance test (IRAT), a team readiness assurance test (TRAT), and a subjective, objective, assessment, and plan (SOAP) note. Student attitudes were assessed using a pre- and post-exercise survey instrument. Students' understanding of possible correct treatment strategies for depression improved. Students were appreciative of this true integration of basic sciences knowledge in a pharmacotherapy course and to have faculty members from both disciplines present to answer questions. Mean student score on the on depression module for the examination was 80.4%, indicating mastery of the content. An exercise led by multiple instructors improved student perceptions of the importance of team-based teaching. Integrated teaching and learning may be achieved when instructors from multiple disciplines work together in the classroom using proven team-based, active-learning exercises.

Medical students' health behaviour and self-reported mental health status by their country of origin: a cross-sectional study.

Numerous previous studies have investigated the lifestyle and self-perceived health status of medical students. This study examined whether students' country of origin contributed to their mental health and health risk behaviour. We conducted our cross-sectional questionnaire survey over four consecutive years (2009-2012). The target population was fourth-year English- and Hungarian-language course medical students at Semmelweis University, Hungary. We gathered data on medical students' health behaviour (tobacco smoking, alcohol consumption, dietary habits and exercise) and mental health status and used analysis of variance (ANOVA) to examine the association between country of origin and mental health. The response rate was 76.1 % for the Hungarian and 63.4 % for the English course students. The mean age of our sample was 24.1 years (SD = 2.42). Only 15.3 % of students reported following dietary recommendations, but 75.0 % reported engaging in vigorous and regular physical exercise. The prevalence of tobacco smoking was 18.6 % and 13.8 % overconsumed alcoholic beverages. Hungarian and Iranian students reported lower mental well-being than Mediterranean, Israeli and Scandinavian students (F(4) = 18.943, p < 0.001, η(2) = 0.103). Results of the multiway ANOVA indicated that both country of origin and exercise showed a significant relationship with mental health: vigorous exercise was associated with better mental health status (F(1) = 5.505, p = 0.019). Medical students' mental health and health behaviour are associated with multiple factors. One of these is country of origin but exercise may also influence mental health. Health promotion programmes organised for medical students should take their country of origin into consideration and should include physical activity.

The role of exercise and gender for physical self-perceptions and importance ratings in Swedish university students.

PubMed

Lindwall, Magnus; Hassmén, Peter

2004-12-01

The purpose of this study was to investigate how scores on the Physical Self-Perception Profile (PSPP), including scores on the Perceived Importance Profile (PIP), were related to self-reported exercise frequency, duration, and gender in sample of Swedish university students. A total of 164 participants completed the PSPP, PIP, and a questionnaire focusing on frequency and duration of exercise. Exercise frequency, duration, and gender predicted best the PSPP sub-domains of Sport Competence and Physical Conditioning. Exercising more frequently, and for a longer time on each occasion was associated with higher PSPP and PIP scores. Women generally displayed lower PSPP scores than men. These results suggest that exercise professionals need to master a range of appropriate exercise strategies, since doubts concerning self-presentation may work against establishing a regular exercise routine.

We conducted four studies to examine the relationship between over-exercise and suicidality. Study 1 investigated whether over-exercise predicted suicidal behavior after controlling for other eating disorder behaviors in a patient sample of 204 women (144 with Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) Bulimia Nervosa [BN]). Study 2 tested the prospective association between over-exercise and acquired capability for suicide (ACS) in a sample of 171 college students followed for 3–4 weeks. Study 3 investigated whether pain insensitivity accounted for the relationship between over-exercise and ACS in a new sample of 467 college students. Study 4 tested whether ACS accounted for the relationship between over-exercise and suicidal behavior in a sample of 512 college students. In Study 1, after controlling for key covariates, over-exercise was the only disordered eating variable that maintained a significant relationship with suicidal behavior. In Study 2, Time 1 over-exercise was the only disordered eating behavior that was associated with Time 2 ACS. In Study 3, pain insensitivity accounted for the relationship between over-exercise and ACS. In Study 4, ACS accounted for the relationship between over-exercise and suicidal behavior. Over-exercise appears to be associated with suicidal behavior, an association accounted for by pain insensitivity and the acquired capability for suicide; notably, this association was found across a series of four studies with different populations.

Pritchard, Laurel M.; Van Kempen, Tracey A.; Williams, Heather; Zimmerberg, Betty

2008-01-01

In this paper we describe a lab exercise developed for the Introduction to Neuroscience course at Williams College. One of a series of five labs, this exercise demonstrated several key principles of behavioral neuroscience. In this lab, students explored the effects of post-weaning housing environment on anxiety-like behavior and psychostimulant sensitivity in rodents. The exercise was intended to emphasize the importance and utility of animal models in neuroscience research and to give students hands-on experience with behavioral neuroscience research techniques. Students tested rats reared in social isolation or environmental enrichment for anxiety-like behaviors on the elevated plus maze, and for spontaneous and amphetamine-induced locomotor activity in the open field. They were then asked to analyze pooled class data and prepare a short lab report. Overall, student performance was excellent. This exercise emerged as a class favorite on course evaluations. Interestingly, the first time this exercise was conducted, the effects of environmental enrichment on anxiety-like behaviors and psychostimulant sensitivity were not consistent with those published in previous studies. Key methodological issues that may account for this discrepancy and contribute to successful implementation by other programs are discussed. PMID:23493884

A Hands-on Exercise in Building Darcy Tubes to Improve Student Understanding of Groundwater Flow

NASA Astrophysics Data System (ADS)

Smith, J. A.

2012-12-01

Teaching undergraduate students about sustainability typically includes discussions of water resources and the flow of groundwater in aquifers. Understanding the flow of groundwater is a fundamental step for students, but one that can easily get mired in equations (e.g., Darcy's Law). In an effort to transform Darcy's Law, which describes flow of fluid through a porous medium, from an abstract concept to a hands-on experiment, I had undergraduate students build working "Darcy tubes" and calculate hydraulic conductivity during a three-hour lab period. At the beginning of the lab period, I presented the students with the materials: three pairs of plastic soda bottles with straight sides, glass tubing, pantyhose (for screens), rubber hosing, sieved sand in three grain sizes (1-2 mm, 0.5-1.0 mm, and 0.25-0.5 mm), and various types of tape and adhesive. After we discussed the basic design of a Darcy tube (inlet and outlet, with two piezometers), the students went to work. Real-time problem-solving was an integral (and exciting) part of the exercise. Within two hours, they had built three Darcy tubes, each filled with a different sand size. The students determined the cross-sectional area of each tube (A) and the distance between the two piezometers (L). We then ran the experiments, using tinted water so that we could more easily tell when the sand in the tubes was saturated. We measured discharge (Q) through the tube and marked the height of the water in each piezometer to calculate difference in hydraulic head (Δh). With the data we had collected, the students were able to calculate hydraulic conductivity (K) using a simple form of Darcy's Law: Q = -KA (Δh/L). Despite the simplicity of the Darcy tubes, the students' K values were reasonable for the sediment types that we used. Student comments on the Darcy tube exercise were overwhelmingly positive. The Darcy tubes could be used in a subsequent lab period for exploration of more advanced concepts, such as breakthrough of contaminants (add water of a different color and collect outflow samples at timed intervals).; One of the Darcy tubes built by undergraduate students.

The impact of instructional design in a case-based, computer-assisted instruction module on learning liver pathology in a medical school pathology course

NASA Astrophysics Data System (ADS)

Latham, Patricia S.

The purpose of this quantitative experimental study was to test the impact of three learning interventions on student learning and satisfaction when the interventions were embedded in the instructional design of case-based, Computer-Assisted Instruction (CAI) modules for learning liver pathology in an in-class, self-study, laboratory exercise during a Year-2 medical school Pathology course. The hypothesis was that inclusion of the learning interventions would enhance student satisfaction in using the CAI and improve subsequent CAI-directed exam performance. Three learning interventions were studied, including the use of microscopic virtual slides instead of only static images, the use of interactive image annotations instead of only still annotations, and the use of guiding questions before presenting new information. Students were randomly assigned to with one of eight CAI learning modules configured to control for each of the three learning interventions. Effectiveness of the CAI for student learning was assessed by student performance on questions included in subsequent CAI-directed exams in a pretest and on posttests immediately after the lab exercise, at two weeks and two months. Student satisfaction and perceived learning was assessed by a student survey. Results showed that the learning interventions did not improve subsequent student exam performance, although satisfaction and perceived learning with use of the CAI learning modules was enhanced. Student class rank was evaluated to determine if the learning interventions might have a differential effect based on class rank, but there were no significant differences. Class rank at the time of the lab exercise was itself the strongest predictor of exam performance. The findings suggest that the addition of virtual slides, interactive annotations and guiding questions as learning interventions in self-study, case-based CAI for learning liver pathology in a medical class room setting are not likely to increase performance on subsequent MCQ-based exams, but student satisfaction with use of the CAI can be enhanced, which could provide to be an incentive for students to use similar CAI learning modules for future self-directed learning.

Medical students' essay-writing skills: criteria-based self- and tutor-evaluation and the role of language background.

PubMed

Chur-Hansen, A

2000-03-01

An exercise is described which aimed to make clear to first-year undergraduate medical students the expected writing skills required for an essay examination in one discipline. Many students were from a non-English speaking background and over one-third of students, regardless of language background, had limited experience in this type of essay writing. For this exercise, a practice essay was written by each student for formative assessment. The essay was rated by a tutor and by the student according to well-defined criteria. This allowed for comparisons to be made in a structured and objective way between the judgements of the student and the assessor. Students found the exercise to be very useful, although whether essay writing skills actually improved could not be established. Students from non-English speaking backgrounds tended to be most harsh in their self-evaluations, yet tutor-evaluations generally showed these students to have better writing skills than other students. Indeed, correlations between self- and tutor-evaluations were quite low. It is evident that students and their educators may be unclear about each others' expectations. By making explicit the requirements of an exercise, misunderstandings may be minimized and it is possible that student performance could improve, though further research is required to verify these hypotheses. It is suggested that students should be encouraged to evaluate their own work and should be instructed in writing skills throughout their medical degree education.

Using a Web-based simulation as a problem-based learning experience: perceived and actual performance of undergraduate public health students.

PubMed

Spinello, Elio F; Fischbach, Ronald

2008-01-01

This study investigated the use of a Web-based community health simulation as a problem-based learning (PBL) experience for undergraduate students majoring in public health. The study sought to determine whether students who participated in the online simulation achieved differences in academic and attitudinal outcomes compared with students who participated in a traditional PBL exercise. Using a nonexperimental comparative design, 21 undergraduate students enrolled in a health-behavior course were each randomly assigned to one of four workgroups. Each workgroup was randomly assigned the semester-long simulation project or the traditional PBL exercise. Survey instruments were used to measure students' attitudes toward the course, their perceptions of the learning community, and perceptions of their own cognitive learning. Content analysis of final essay exams and group reports was used to identify differences in academic outcomes and students' level of conceptual understanding of health-behavior theory. Findings indicated that students participating in the simulation produced higher mean final exam scores compared with students participating in the traditional PBL (p=0.03). Students in the simulation group also outperformed students in the traditional group with respect to their understanding of health-behavior theory (p=0.04). Students in the simulation group, however, rated their own level of cognitive learning lower than did students in the traditional group (p=0.03). By bridging time and distance constraints of the traditional classroom setting, an online simulation may be an effective PBL approach for public health students. Recommendations include further research using a larger sample to explore students' perceptions of learning when participating in simulated real-world activities. Additional research focusing on possible differences between actual and perceived learning relative to PBL methods and student workgroup dynamics is also recommended.

This cross-sectional survey study examined exercise, sleep quality, and quality of life (QOL) in 1230 Taiwanese university students. Compared with women, men had higher body mass index (BMI) (22.3 ± 4.1 vs 20.7 ± 3.5 kg/m(2)), higher exercise frequency (2.6 ± 1.7 vs 2.0 ± 1.4 d/wk), better sleep quality (global Pittsburgh Sleep Quality Index 6.0 ± 2.8 vs 6.5 ± 2.7), better physical QOL (physical component summary 52.7 ± 6.2 vs 51.7 ± 6.6), and higher reporting of good self-perceived health (62.2% vs 43.3%) (P <01). However, gender differences were nonsignificant after multivariable adjustment. Exercise frequency, sleep quality, and QOL were significantly intercorrelated. After multivariable adjustment, self-perceived health and satisfaction with exercise participation predicted quality of sleep and QOL (P <01). Exercise frequency was positively correlated (P =012), and exercise intensity was negatively associated (P <001) with physical QOL. In conclusion, those who regularly exercised (at least 1 d/wk or 2.5 h/wk) had better QOL. Students with better self-perceived health or satisfaction with exercise participation also had better quality of sleep and better QOL. © 2016 APJPH.

2012-10-01

This paper presents a laboratory exercise that introduces students to the use of video analysis software and the Lenz's law demonstration. Digital techniques have proved to be very useful for the understanding of physical concepts. In particular, the availability of affordable digital video offers students the opportunity to actively engage in kinematics in introductory-level physics.1,2 By using digital videos frame advance features and "marking" the position of a moving object in each frame, students are able to more precisely determine the position of an object at much smaller time increments than would be possible with common time devices. Once the student collects data consisting of positions and times, these values may be manipulated to determine velocity and acceleration. There are a variety of commercial and free applications that can be used for video analysis. Because the relevant technology has become inexpensive, video analysis has become a prevalent tool in introductory physics courses.

Perceptions about exercise and intrinsic motivation of students attending a health-related physical education program.

2003-12-01

The present study examined effects of sex, attitude towards physical activity, perceived barriers for participation in physical activity, and students' perception of their parents' participation in physical activity on the intrinsic motivation of students participating in a health related program in physical education. 643 students (303 boys and 340 girls) responded to questionnaires measuring intrinsic motivation, attitudes towards physical activity, perceived barriers to exercise and perceived parents' participation in physical activity. Mean age was 12.9 yr. (SD=1.2, range 11-14 years). Analysis indicated that students' intrinsic motivation towards the program was influenced by perceived barriers to exercise. Sex, attitudes towards physical activity, and perceived parents' participation in physical activity seem to be less important.

Substance use and exercise have opposite trajectories in young adulthood, and research indicates that peers are influential for both of these health behaviors, but simultaneous investigations of peer associations with substance use and exercise have not been conducted. Use a college residence hall peer network to examine associations between peer behaviors and alcohol use, marijuana use, and exercise behavior. 129 undergraduates (51.9% female, 48.1% non-Hispanic White; 84.5% first-year students) in one residence hall completed a Web-based survey of substance use and exercise and identified up to 10 students in the residence hall who were important to them. Two social network analytic methods, community detection cluster analysis and network autocorrelation modeling, were used to identify peer groupings and to examine the associations between peer and participant behaviors, respectively. Participants nominated an average of 4.1 residence hall members, and 53.9% of the ties were reciprocal. 6 clusters were identified that differed significantly on demographics, college activities, substance use, and exercise. Weekly volume of alcohol consumed among nominated peers was significantly associated with that of participants, and all other covariates, including gender and athlete status, were not significant. Peer marijuana use also was associated with participant use after controlling for covariates. Exercise levels of nominated peers were not associated with exercise levels of participants. College student networks may be good targets for health-related prevention programs. Programs that use close-proximity peers to influence the behavior of others might be more effective with substance use as the target behavior than exercise.

Reactions to Diversity: Using Theater to Teach Medical Students about Cultural Diversity.

PubMed

Ivory, Kimberley D; Dwyer, Paul; Luscombe, Georgina

2016-01-01

Training medical students to understand the effects of culture and marginalization on health outcomes is important to the future health of increasingly diverse populations. We devised and evaluated a short training module on working with diversity to challenge students' thinking about the role of both patient and practitioner culture in health outcomes. The workshop combined didactic teaching about culture as a social determinant of health using the cultural humility model, interactive exercises, and applied theater techniques. We evaluated changes in the students' perceptions and attitudes over time using the Reaction to Diversity Inventory. There was initial significant improvement. Women and students with no past diversity training responded best. However, scores largely reverted to baseline over 12 months.

Increasing students' physical activity during school physical education: rationale and protocol for the SELF-FIT cluster randomized controlled trial.

PubMed

Ha, Amy S; Lonsdale, Chris; Lubans, David R; Ng, Johan Y Y

2017-07-11

The Self-determined Exercise and Learning For FITness (SELF-FIT) is a multi-component school-based intervention based on tenets of self-determination theory. SELF-FIT aims to increase students' moderate-to-vigorous physical activity (MVPA) during physical education lessons, and enhance their autonomous motivation towards fitness activities. Using a cluster randomized controlled trial, we aim to examine the effects of the intervention on students' MVPA during school physical education. Secondary 2 students (approximately aged 14 years) from 26 classes in 26 different schools will be recruited. After baseline assessments, students will be randomized into either the experimental group or wait-list control group using a matched-pair randomization. Teachers allocated to the experimental group will attend two half-day workshops and deliver the SELF-FIT intervention for 8 weeks. The main intervention components include training teachers to teach in more need supportive ways, and conducting fitness exercises using a fitness dice with interchangeable faces. Other motivational components, such as playing music during classes, are also included. The primary outcome of the trial is students' MVPA during PE lessons. Secondary outcomes include students' leisure-time MVPA, perceived need support from teachers, need satisfaction, autonomous motivation towards physical education, intention to engage in physical activity, psychological well-being, and health-related fitness (cardiorespiratory and muscular fitness). Quantitative data will be analyzed using multilevel modeling approaches. Focus group interviews will also be conducted to assess students' perceptions of the intervention. The SELF-FIT intervention has been designed to improve students' health and well-being by using high-intensity activities in classes delivered by teachers who have been trained to be autonomy needs supportive. If successful, scalable interventions based on SELF-FIT could be applied in physical education at large. The trial is registered at the Australia New Zealand Clinical Trial Registry (Trial ID: ACTRN12615000633583 ; date of registration: 18 June 2015).

Responses to life stressors are associated with negative behaviors that may increase risk for illness and injury. The effect of high intensity exercise in reducing reactivity to psychological stress has been well documented among older people. The purpose of this study was to ascertain the effect of weight-training versus aerobic dance on psychological stress in college students. 45 students participated in a weight-training course, 35 students participated in aerobic dance classes, and 34 students served as a control group. The Survey of Recent Life Experiences was used to appraise stressfulness of current experiences before and after exercise intervention. On immediate retest after 8 wk. of weight-training perceived stress was significantly reduced when compared with an 8-wk. aerobic dance program, but there were no significant differences between the control group and the weight-training group or the aerobic dance group. These results suggest that a regular routine of low intensity exercise such as weight-training may reduce perceived stress on an immediate test.

A Flipped Pedagogy for Expert Problem Solving

NASA Astrophysics Data System (ADS)

Pritchard, David

The internet provides free learning opportunities for declarative (Wikipedia, YouTube) and procedural (Kahn Academy, MOOCs) knowledge, challenging colleges to provide learning at a higher cognitive level. Our ``Modeling Applied to Problem Solving'' pedagogy for Newtonian Mechanics imparts strategic knowledge - how to systematically determine which concepts to apply and why. Declarative and procedural knowledge is learned online before class via an e-text, checkpoint questions, and homework on edX.org (see http://relate.mit.edu/physicscourse); it is organized into five Core Models. Instructors then coach students on simple ``touchstone problems'', novel exercises, and multi-concept problems - meanwhile exercising three of the four C's: communication, collaboration, critical thinking and problem solving. Students showed 1.2 standard deviations improvement on the MIT final exam after three weeks instruction, a significant positive shift in 7 of the 9 categories in the CLASS, and their grades improved by 0.5 standard deviation in their following physics course (Electricity and Magnetism).

2011-01-01

Objective To implement a role-reversal exercise to increase first-year pharmacy students' awareness of communication barriers in the health care setting, especially for deaf and hard-of-hearing patients. Design Volunteers from the local deaf community conducted Deaf Strong Hospital, a role-reversal exercise in which students were the “patients.” Students navigated through a reception area, encounter with a physician, and having a prescription filled at a pharmacy without receiving or using any spoken language. Assessment A debriefing session was held in which small groups of students had the opportunity to ask questions of a panel of deaf and hard-of-hearing volunteers. On a survey administered to assess students' learning, 97% agreed or strongly agreed that the experience would likely impact their attitudes and behavior in future interactions with patients who did not speak English. Conclusions The role-reversal exercise was an effective method of teaching students that the delivery of health care is dependent on adequate communication between health care providers and the patient.

Tandon, Vishal; Peck, Walter

2013-01-01

Three microfluidics-based laboratory exercises were developed and implemented in a high school science classroom setting. The first exercise demonstrated ways in which flows are characterized, including viscosity, turbulence, shear stress, reversibility, compressibility, and hydrodynamic resistance. Students characterized flows in poly(dimethylsiloxane) microfluidic devices in the other two exercises, where they observed the mixing characteristics of laminar flows, and conservation of volumetric flow rate for incompressible flows. In surveys, the students self-reported increased knowledge of microfluidics, and an improved attitude toward science and nanotechnology.

ABSTEACT Despite the reported poor dietary habits and risk of weight gain in college students, they remain understudied in Mexico. Mexican college students are in a rapidly changing economic environment; a shift from a traditional, homemade cuisine to a diet more heavily influenced by an industrialized culture seems to be occurring, potentially affecting the quality of their dietary intake. A health and nutrition survey was conducted among 450 Mexican college students to study the relationship between sociodemographic factors and diet quality. Dietary data were used to build macro- and micronutrient scores, dichotomized as low and normal quality. Adjusted odds (OR [95% CI]) were computed to determine the probability of low dietary quality. Breakfast skipping (5.3 [1.2, 22.7]) and risk of anxiety (2.3 [1.3, 4.4]) were associated with a greater risk of low macronutrient quality, and caloric intake < 1,800 kcal (5.8 [3.5, 9.7]), breakfast skipping (3.7 [1.4, 10.3]), vigorous exercise ≤ 1 h/wk (2.6 [1.3, 5.2]), and soda consumption > 250 mL/d (2.0 [1.2, 3.3]) with low micronutrient quality.

2004-03-01

This observational cross-sectional study was done to determine bone mass in physicians and to determine if variables, such as calcium intake and exercise, were related to their bone mass. One-hundred physicians of different ethnicities (African, African American, Asian, Caribbean, and Hispanic) were studied. Using dual-energy x-ray absorptiometry (DEXA), bone mass (BMD) of the lumbar spine and hips was measured. A validated questionnaire was used to determine the daily calcium intake and exercise. Student t-test, logistic regression, and Pearson chi-square were used to analyze the data. The study population consisted of 52% men and 48% women, with a mean age of 42 years old and a body mass index of 18.5 to 39.9 kg/m2. Low BMD occurred in 68% of the physicians (osteoporosis in 12%, osteopenia in 56%). Low calcium intake was found in 71%-14% of whom had osteoporosis and 49% osteopenia. Two-thirds of the physicians had inadequate exercise; 57% of this group had decreased BMD (osteoporosis in 9%, osteopenia in 38%). There was no statistical significance between BMD and calcium intake or exercise. A high percentage of the physicians in this unique study had a reduced BMD. Most of the physicians with low BMD were less than 45 years of age. This study indicates the need to define BMD in a larger cohort of young, ethnically diverse clinicians, and other health workers.

Practical sessions in undergraduate medical education are often costly and have to face constraints in terms of available laboratory time and practice materials (e.g. blood samples from animals). This makes it difficult to increase the time each student spends at the laboratory. We consider that it would be possible to improve the effectiveness of the laboratory time by providing the students with computer-based simulations for prior rehearsal. However, this approach still presents issues in terms of development costs and distribution to the students. This study investigates the employment of low-cost simulation to allow medical students to rehearse practical exercises through a web-based e-learning environment. The aim is to maximize the efficiency of laboratory time and resources allocated by letting students become familiarized with the equipment and the procedures before they attend a laboratory session, but without requiring large-scale investment. Moreover, students can access the simulation via the Internet and rehearse at their own pace. We have studied the effects of such a simulation in terms of impact on the laboratory session, learning outcomes and student satisfaction. We created a simulation that covers the steps of a practical exercise in a Physiology course (measuring hematocrit in a blood sample). An experimental group (EG, n=66) played the simulation 1 week before the laboratory session. A control group (CG, n=77) attended the laboratory session without playing the simulation. After the session, all students completed a survey about their perception of the difficulty of the exercise on a scale of 1-10 and the HCT final value that they obtained. The students in the EG also completed a survey about their satisfaction with the experience. After the laboratory session, the perceived difficulty of the procedure was lower on average in the EG compared to the CG (3.52 vs. 4.39, 95% CI: 0.16-1.57, P=.016). There was no significant difference in terms of perceived difficulty using the equipment. The HCT measures reported by the EG group also presented a much lower dispersion, meaning a higher reliability, in determining the HCT value (3.10 vs. 26.94, SD; variances significantly different, P<.001, F: 75.25, Dfd: 68.19 for EG and CG). In the satisfaction test, the majority of the students in the EG reported that the experience was positive or very positive (80.7%) and reported that it had helped them to identify and use the equipment (78%) and to perform the exercise (66%). The simulation was well received by students in the EG, who felt more comfortable during the laboratory session, and it helped them to perform the exercise better, obtaining more accurate results, which indicates more effective training. EG students perceived the procedure as easier to perform, but did not report an improvement in the perceived difficulty in using the equipment. The increased reliability demonstrates that low-cost simulations are a good complement to the laboratory sessions. Copyright 2010 Elsevier Ireland Ltd. All rights reserved.

Effectiveness of inquiry-based learning in an undergraduate exercise physiology course.

PubMed

Nybo, Lars; May, Michael

2015-06-01

The present study was conducted to investigate the effects of changing a laboratory physiology course for undergraduate students from a traditional step-by-step guided structure to an inquiry-based approach. With this aim in mind, quantitative and qualitative evaluations of learning outcomes (individual subject-specific tests and group interviews) were performed for a laboratory course in cardiorespiratory exercise physiology that was conducted in one year with a traditional step-by-step guided manual (traditional course) and the next year completed with an inquiry-based structure (I-based course). The I-based course was a guided inquiry course where students had to design the experimental protocol and conduct their own study on the basis of certain predefined criteria (i.e., they should evaluate respiratory responses to submaximal and maximal exercise and provide indirect and direct measures of aerobic exercise capacity). The results indicated that the overall time spent on the experimental course as well as self-evaluated learning outcomes were similar across groups. However, students in the I-based course used more time in preparation (102 ± 5 min) than students in the traditional course (42 ± 3 min, P < 0.05), and 65 ± 5% students in the I-based course searched for additional literature before experimentation compared with only 2 ± 1% students in the traditional course. Furthermore, students in the I-based course achieved a higher (P < 0.05) average score on the quantitative test (45 ± 3%) compared with students in the traditional course (31 ± 4%). Although students were unfamiliar with cardiorespiratory exercise physiology and the experimental methods before the course, it appears that an inquiry-based approach rather than one that provides students with step-by-step instructions may benefit learning outcomes in a laboratory physiology course.

Designing a flashcard with knowledge pills for learning to solve chemistry exercises

NASA Astrophysics Data System (ADS)

Cancela, Angeles; Sanchez, Angel; Maceiras, Rocio

2012-08-01

Nowadays, universities tend to promote more learner-centred learning, creating a more interactive and motivational environment for students and teachers. This paper describes an expanded framework to help chemical educators to construct a quiz for solution of chemical exercises in their courses. The novelty of this contribution is that the proposed tool combines a flashcards-based method with knowledge pills. The framework has three levels: definition of problem for a teacher; the quiz; use of the quiz for the student. The tool could provide predefined or automatically generated exercises of chemicals. Students could practise where and whenever they like via the Internet. Theirs answers would be registered automatically by the tool and if the students have doubts about any of the questions, they can see a knowledge pill with a teacher explanation about the solution of the exercise. Moreover, they would be able to check their scores from the tests. Once the flashcards were designed and produced, the opinions of other lecturers and students about them were considered. Both groups considered that the tool could be useful to improve the students' learning process. For future work, this design will be used with the students and its effectiveness will be analysed.

Education in hydrology is changing rapidly due to diversification of students, emergent major scientific and practical challenges that our discipline must engage with, shifting pedagogic ideas and higher education environments, the need for students to develop new discipline specific and transferrable skills, and the advent of innovative technologies for learning and teaching. This paper focuses on new technologies in the context of learning and teaching in Physical Geography and reflects on the implications of our experiences for education in hydrology. We evaluate the experience of designing and trialling novel mobile technology-based field exercises and a virtual field tour for a Year 1 undergraduate Physical Geography module at a UK university. The new exercises are based on using and obtaining spatial data, operation of meteorological equipment (explained using an interactive DVD), and include introductions to global positioning systems (GPS) and geographical information systems (GIS). The technology and exercises were well received in a pilot study and subsequent rolling-out to the full student cohort (∼150 students). A statistically significant improvement in marks was observed following the redesign. Although the students enjoyed using mobile technology, the increased interactivity and opportunity for peer learning were considered to be the primary benefits by students. This is reinforced further by student preference for the new interactive virtual field tour over the previous "show-and-tell" field exercise. Despite the new exercises having many advantages, exercise development was not trivial due to the high start-up costs, the need for provision of sufficient technical support and the relative difficulty of making year-to-year changes (to the virtual field tour in particular). Our experiences are highly relevant to the implementation of novel learning and teaching technologies in hydrology education.

The Black Hills of South Dakota exhibits many fine examples of stream piracy that are very suitable for teaching geomorphology lab exercises. This lab goes beyond standard topographic map interpretation by using geologic maps, well logs, gravel provenance and other types of data to teach students about stream piracy. Using a step-by-step method in which the lab exercises ramp up in difficulty, students hone their skills in deductive reasoning and data assimilation. The first exercises deal with the identification of stream piracy at a variety of spatial scales and the lab culminates with an exercise on landscape evolution and drainage rearrangement.

Along paths converging to Bengt Saltin’s early contributions in exercise physiology

PubMed Central

Schantz, P

2015-01-01

A fascinating chain of events led in 1941 to the formation of the Department of Physiology at the Royal Gymnastic Central Institute (GCI) in Stockholm, Sweden. Erik Hohwü Christensen, from the scientifically advanced Lindhard School in Copenhagen became its first professor. A central research question for him concerned determining the limiting factors for maximal physical performance in man. This was the academic setting where the sports interested medical student Bengt Saltin was introduced to exercise physiology. In the summer of 1959, he became involved in a study on intermittent vs continuous running. A doctoral project, with Per-Olof Åstrand as his tutor, resulted in 1964 as the thesis “Aerobic work capacity and circulation at exercise in man. With special reference to the effect of prolonged exercise and/or heat exposure”. In the decade that followed, Saltin continued along that path. However, he also added a vital research line involving pioneering studies on skeletal muscles in the exercising man, a series of novel studies on the physiological demands in various sports, and studies of the effects of physical training within the general population.

Exercise correlates with alcohol use, but the nature of this relation and the extent to which it is maladaptive remains unclear. Urgency and motives for engaging in drinking and exercise might indicate when these behaviors are problematic. The current study examined whether urgency moderated the association between exercise motivated by weight loss and drinking. College students (N = 589, 45.7% male) completed the study during the spring of 2012. Participants completed self-report assessment measures, including frequency/quantity of alcohol consumption, exercise for weight loss, and urgency, during a single session. Negative urgency moderated the relation between exercise and alcohol consumption in men but not women; the link between excessive exercise and alcohol use was stronger for men with higher levels of urgency. Further clarification of the mechanisms underlying alcohol use and physical activity-particularly maladaptive approaches to exercise-will inform health interventions among college students.

Perceived Exercise Benefits and Barriers of Non-Exercising Female University Students in the United Kingdom

Lovell, Geoff P; Ansari, Walid El; Parker, John K

2010-01-01

Many individuals do not engage in sufficient physical activity due to low perceived benefits and high perceived barriers to exercise. Given the increasing incidence of obesity and obesity related health disorders, this topic requires further exploration. We used the Exercise Benefits/Barriers Scale to assess perceived benefit and barrier intensities to exercise in 200 non-exercising female university students (mean age 19.3 years, SD = 1.06) in the UK. Although our participants were selected because they self reported themselves to be non-exercising, however they reported significantly higher perceived benefits from exercise than perceived barriers to exercise [t(199) = 6.18, p < 0.001], and their perceived benefit/barrier ratio was 1.33. The greatest perceived benefit from exercise was physical performance followed by the benefits of psychological outlook, preventive health, life enhancement, and then social interaction. Physical performance was rated significantly higher than all other benefits. Psychological outlook and preventive health were not rated significantly different, although both were significantly higher than life enhancement and social interaction. Life enhancement was also rated significantly higher than social interaction. The greatest perceived barrier to exercise was physical exertion, which was rated significantly higher than time expenditure, exercise milieu, and family discouragement barriers. Implications from this investigation for the design of physical activity programmes include the importance, for females, of a perception of high benefit/barrier ratio that could be conducive to participation in exercise. Applied interventions need to assist female students to ‘disengage’ from or overcome any perceived ‘unpleasantness’ of physical exertion during physical activity (decrease their perceived barriers), and to further highlight the multiple health and other benefits of regular exercising (increase their perceived benefits).

2012-07-01

This article presents two integrated laboratory exercises intended to show students the role of α-amylases (AAMYs) in saliva and detergents. These laboratory practicals are based on the determination of the enzymatic activity of amylase from saliva and different detergents using the Phadebas test (quantitative) and the Lugol test (qualitative) under different conditions (e.g. variations in temperature and alkalinity). This work also proposes the study of enzyme stability in the presence of several surfactants and oxidizing agents using the same technical approach. The proposed laboratory exercises promote the understanding of the physiological function of this enzyme and the biotechnological applications of AAMYs in the detergent industry. The exercises also promote the understanding that the enzymatic stability and performance are dependent on the organism of origin, and if necessary, these properties could be modified by genetic engineering. In addition, this article reinforces the development of laboratory skills, problem-solving capabilities, and the ability to write a laboratory report. The exercises are proposed primarily as an undergraduate project for advanced students in the biochemical and biotechnological sciences. These laboratory practicals are complementary to the previously published BAMBED article (Biochemistry and Molecular Biology Education Vol. 39, No. 4, pp. 280-290, 2011) on detergent proteases.

Burleson, Kathryn M.; Martinez-Vaz, Betsy M.

2011-01-01

In this laboratory exercise, students were taught concepts of microbiology and scientific process through an everyday activity — cosmetic use. The students’ goals for the lab were to develop a hypothesis regarding microbial contamination in cosmetics, learn techniques to culture and differentiate microorganisms from cosmetics, and propose best practices in cosmetics use based on their findings. Prior to the lab, students took a pretest to assess their knowledge of scientific hypotheses, microbiology, and cosmetic safety. In the first week, students were introduced to microbiological concepts and methodologies, and cosmetic terminology and safety. Students completed a hypothesis-writing exercise before formulating and testing their own hypotheses regarding cosmetic contamination. Students provided a cosmetic of their own and, in consultation with their lab group, chose one product for testing. Samples were serially diluted and plated on a variety of selective media. In the second week, students analyzed their plates to determine the presence and diversity of microbes and if their hypotheses were supported. Students completed a worksheet of their results and were given a posttest to assess their knowledge. Average test scores improved from 5.2 (pretest) to 7.8 (posttest), with p-values < 0.0001. Seventy-nine percent (79%) of students correctly identified hypotheses that were not falsifiable or lacked variables, and 89% of students improved their scores on questions concerning safe cosmetic use. Ninety-one percent (91%) of students demonstrated increased knowledge of microbial concepts and methods. Based on our results, this lab is an easy, yet effective, way to enhance knowledge of scientific concepts for nonmajors, while maintaining relevance to everyday life. PMID:23653761

Using an international p53 mutation database as a foundation for an online laboratory in an upper level undergraduate biology class.

A two-part laboratory exercise was developed to enhance classroom instruction on the significance of p53 mutations in cancer development. Students were asked to mine key information from an international database of p53 genetic changes related to cancer, the IARC TP53 database. Using this database, students designed several data mining activities to look at the changes in the p53 gene from a number of perspectives, including potential cancer-causing agents leading to particular changes and the prevalence of certain p53 variations in certain cancers. In addition, students gained a global perspective on cancer prevalence in different parts of the world. Students learned how to use the database in the first part of the exercise, and then used that knowledge to search particular cancers and cancer-causing agents of their choosing in the second part of the exercise. Students also connected the information gathered from the p53 exercise to a previous laboratory exercise looking at risk factors for cancer development. The goal of the experience was to increase student knowledge of the link between p53 genetic variation and cancer. Students also were able to walk a similar path through the website as a cancer researcher using the database to enhance bench work-based experiments with complementary large-scale database p53 variation information. © 2014 The International Union of Biochemistry and Molecular Biology.

State of laboratory manual instruction in California community college introductory (non-majors) biology laboratory instruction

NASA Astrophysics Data System (ADS)

Priest, Michelle

College students must complete a life science course prior to graduation for a bachelor's degree. Generally, the course has lecture and laboratory components. It is in the laboratory where there are exceptional opportunities for exploration, challenge and application of the material learned. Optimally, this would utilize the best of inquiry based approaches. Most community colleges are using a home-grown or self written laboratory manual for the direction of work in the laboratory period. Little was known about the motivation, development and adaptation of use. It was also not known about the future of the laboratory manuals in light of the recent learning reform in California Community Colleges, Student Learning Outcomes. Extensive interviews were conducted with laboratory manual authors to determine the motivation, process of development, who was involved and learning framework used in the creation of the manuals. It was further asked of manual authors their ideas about the future of the manual, the development of staff and faculty and finally, the role Student Learning Outcomes would play in the manual. Science faculty currently teaching the non-majors biology laboratories for at least two semesters were surveyed on-line about actual practice of the manual, assessment, manual flexibility, faculty training and incorporation of Student Learning Outcomes. Finally, an evaluation of the laboratory manual was done using an established Laboratory Task Analysis Instrument. Laboratory manuals were evaluated on a variety of categories to determine the level of inquiry instruction done by students in the laboratory section. The results were that the development of homegrown laboratory manuals was done by community colleges in the Los Angeles and Orange Counties in an effort to minimize the cost of the manual to the students, to utilize all the exercises in a particular lab and to effectively utilize the materials already owned by the department. Further, schools wanted to utilize the current faculty research expertise and knowledge. Unfortunately, laboratory manual authors had no real learning framework in the development of the manual. Based on the LAI, most manuals focused on the lowest levels of inquiry based instruction. Most manuals focused exercises on cell and molecular topics. The manuals had little student exploration, creation or design in the laboratory exercise and no option for repeating the exercise. There was a clear desire of faculty and authors to improve the laboratory experience and manual. Authors and faculty wished to include more inquiry and utilize the best of Student Learning Outcome (SLO) methodologies. Authors and the laboratory manuals have a major disconnect in that authors have clear desires inquiry based learning for the manual but do not effectively implement the inquiry based learning for various reasons. The manuals themselves, laboratory manuals themselves are not robust inquiry based learning models to maximize student learning. Authors and faculty are disconnected in that authors know what they want their manuals to do...but do not effectively communicate that to faculty. Finally, schools are in a "wait and see" approach as to when to integrate the latest learning theory mandated by the Chancellors Office -- Student Learning Outcomes.

Balance training is an effective intervention to improve static postural sway and balance. The purpose of the present study was to investigate the effectiveness of the Nintendo Wii Fit Plus exercises for improving balance ability in healthy collegiate students in comparison with a typical balance training program. Forty students were randomly divided into two groups, a traditional (T group) and a Nintendo Wii group (W group) performed an 8 week balance program. The "W group" used the interactive games as a training method, while the "T group" used an exercise program with mini trampoline and inflatable discs (BOSU). Pre and Post-training participants completed balance assessments. Two-way repeated measures analyses of variance (ANOVAs) were conducted to determine the effect of training program. Analysis of the data illustrated that both training program groups demonstrated an improvement in Total, Anterior-posterior and Medial Lateral Stability Index scores for both limbs. Only at the test performed in the balance board with anterior-posterior motion, the improvement in balance ability was greater in the "T group" than the "W group", when the assessment was performed post-training (p=0.023). Findings support the effectiveness of using the Nintendo Wii gaming console as a balance training intervention tool.

The ‘unskilled and unaware’ effect is linear in a real-world setting

Sawdon, Marina; Finn, Gabrielle

2014-01-01

Self-assessment ability in medical students and practising physicians is generally poor, yet essential for academic progress and professional development. The aim of this study was to determine undergraduate medical students' ability to self-assess their exam performance accurately in a real-world, high-stakes exam setting, something not previously investigated. Year 1 and Year 2 medical students (n = 74) participated in a self-assessment exercise. Students predicted their exam grade (%) on the anatomy practical exam. This exercise was completed online immediately after the exam. Students' predicted exam grades were correlated with their actual attained exam grades using a Pearson's correlation. Demographic data were analysed using an independent t-test. A negative correlation was found between students' overall predicted and attained exam grades (P < 0.0001). There was a significant difference between the students' predicted grades and actual grades in the bottom, 3rd and top (P < 0.0001), but not 2nd quartiles of participants. There was no relationship between the students' entry status into medical school and self-assessment ability (Year 1: P = 0.112; Year 2: P = 0.236) or between males and females (Year 1: P = 0.174). However, a relationship was determined for these variables in Year 2 (P = 0.022). The number of hours of additional self-directed learning undertaken did not influence students' self-assessment in both years. Our results demonstrate the ‘unskilled and unaware’ phenomenon in a real-world, high-stakes and practice-related setting. Students in all quartiles were unable to self-assess their exam performance, except for a group of mid-range students in the 2nd quartile. Poor performers were shown to overestimate their ability and, conversely, high achievers to underestimate their performance. We present evidence of a strong, significant linear relationship between medical students' ability to self-assess their performance in an anatomy practical exam, and their actual performance; in a real world setting. Despite the limited ability to self-assess reported in the literature, our results may inform approaches to revalidation, which currently frequently rely on an ability to self-assess. PMID:23781887

Social physique anxiety, obligation to exercise, and exercise choices among college students.

Chu, Hui-Wen; Bushman, Barbara A; Woodard, Rebecca J

2008-01-01

The authors examined relationships among social physique anxiety, obligation to exercise, and exercise choices. College students (N = 337; 200 women, 137 men) volunteered to complete 3 questionnaires: the Social Physique Anxiety Scale (SPAS), Obligatory Exercise Questionnaire (OEQ), and Physical Activity Specification Survey (PASS). On the SPAS, men (M score = 31.9 +/- 8.8) differed from women (M score = 37.3 +/- 8.3; p = .001). Men (M score = 43.0 +/- 9.9) and women (M score = 43.0 +/- 9.6) responded similarly (p = .94) on the OEQ. There was no interaction between sex and exercise level on the SPAS or OEQ. When separated by low, medium, and high SPAS scores, neither OEQ nor exercise scores differed. Obligation to exercise appears to be similar for both sexes. Women, however, appear to have higher levels of anxiety regarding how others evaluate their physique than do men. The combination of level of activity and sex do not appear to be associated with social physique anxiety or obligation to exercise.

Blogging in a biostatistics and research design graduate dental course: for learning or interaction?

2010-04-01

The use of the Internet in health professions education has markedly increased in recent years. There is a need to understand the methods used by students to benefit from Internet-based teaching methods, especially those initially designed to promote social interaction such as blogs. This study describes how students used a blog in a biostatistics and research design graduate dental course. The aims of the blog were to offer exercises to train students for the exam and to enhance interaction among students and between students and instructor. Some features of the blog were modified to suit the course. Posts and comments were counted and classified by type, and their time statistics were analyzed. Students filled out a questionnaire to indicate whether and how exactly they used the blog or reasons for not using it. The relation between final exam scores and different methods of using the blog was assessed. Most of the posts were by the instructor offering exercises and model answers, whereas most of the comments were by students answering the exercises. Students were significantly more satisfied with blog uses related to interaction than with uses related to exercises (9.15+/-1.19, 8.73+/-1.34, P=0.001). The most frequently cited reason for not using the blog was lack of time. The most frequently reported method of using the blog was reading exercises and answers without actively contributing to the blog. Methods of using the blog significantly associated with higher scores in the final exam were actively contributing to the blog by posts or comments and interacting with colleagues. The main advantage of using the blog was promoting interaction between students and instructor, which is essential for the success of online learning in particular and adult learning in general.

　Osaka University of Pharmaceutical Sciences has included an evidence-based medicine (EBM) exercise in the introductory education for clinical practice for 4th-year pharmacy students since 2015. The purpose of this exercise is to learn the process of practice and basic concepts of EBM, especially to cultivate the practical ability to solve patients' problems and answer their questions. Additionally, in 2016, we have attempted flipped teaching. The students are instructed to review the basic knowledge necessary for active learning in this exercise by watching video teaching materials and to bring reports summarizing the contents on the flipped teaching days. The program includes short lectures [overview of EBM, document retrieval, randomized controlled trials (RCTs), and systematic review], exercises [patient, intervention, comparison, outcome (PICO) structuring, critical appraisal of papers in small groups with tutors], and presentations. The program includes: step 1, PICO structuring based on scenarios; step 2, critical appraisal of English-language papers on RCTs using evaluation worksheets; and step 3, reviewing the results of the PICO exercise with patients. The results of the review are shared among groups through general discussion. In this symposium, I discuss students' attitudes, the effectiveness of small group discussions using flipped teaching, and future challenges to be addressed in this program.

[Purpose] Efficient management using exercise programs with various benefits should be provided by educational institutions for children in their growth phase. We analyzed the heart rates of children during ski simulator exercise and the Harvard step test to evaluate the cardiopulmonary endurance by calculating their post-exercise recovery rate. [Subjects and Methods] The subjects (n = 77) were categorized into a normal weight and an overweight/obesity group by body mass index. They performed each exercise for 3 minutes. The cardiorespiratory endurance was calculated using the Physical Efficiency Index formula. [Results] The ski simulator and Harvard step test showed that there was a significant difference in the heart rates of the 2 body mass index-based groups at each minute. The normal weight and the ski-simulator group had higher Physical Efficiency Index levels. [Conclusion] This study showed that a simulator exercise can produce a cumulative load even when performed at low intensity, and can be effectively utilized as exercise equipment since it resulted in higher Physical Efficiency Index levels than the Harvard step test. If schools can increase sport durability by stimulating students' interests, the ski simulator exercise can be used in programs designed to improve and strengthen students' physical fitness.

Limitations on didactic time pose barriers to teaching non-directive pregnancy options counseling. This study set out to explore the use of an online module to support trainee performance in a pregnancy options counseling standardized-patient exercise implemented among third-year medical students, and to examine the effect of clinical experience on student performance. An online module was developed. A convenience sample of forty-six student performances in a family medicine clerkship participated in a standardized patient exercise. Trained faculty rated performances. Students completed a self-assessment and provided feedback on the online module. Chi-square and Mann-Whitney-U tests were used to analyze data. Three coders qualitatively examined narrative student comments. Thirty-four students passed, 11 achieved a minimal pass, and one failed. The mean global rating from faculty was 2.8 (pass). Students with prior clinical experience significantly outperformed those without on the global rating scale with mean scores of 3.1 compared to 2.7, respectively (p=.044). All students agreed that the online module helped prepare them for the exercise. Qualitative analysis of students' feedback on the module revealed strengths in content and pedagogy. In their self-assessments, all but two students referred to content explicitly conveyed in the module. All students agreed that an online module supported their performance of non-directive pregnancy options counseling skills. Prior clinical experience was associated with improved performance. This module, along with the simulated exercise, can be implemented as a blended learning exercise without additional faculty teaching effort in standardized patient resource centers. Students agreed that an online module facilitates simulated performance of non-directive pregnancy options counseling skills. Future work should compare the impact of this approach to others, and explore the additional training needed to maintain and build on initial learning. Copyright © 2016 Elsevier Inc.

2016-01-01

Many university students experience high levels of study-related fatigue. This high prevalence, and the negative impact of fatigue on health and academic performance, call for prevention and reduction of these symptoms. The primary aim of the current study was to investigate to what extent an exercise intervention is effective in reducing three indicators of study-related fatigue (emotional exhaustion, overall fatigue, and need for recovery). Effects of exercise on secondary outcomes (sleep quality, self-efficacy, physical fitness, and cognitive functioning) were also investigated. Participants were students with high levels of study-related fatigue, currently not exercising or receiving other psychological or pharmacological treatments, and with no medical cause of fatigue. They were randomly assigned to either a six-week exercise intervention (low-intensity running three times a week, n = 49) or wait list (no intervention, n = 48). All participants were measured before the intervention (T0), and immediately after the intervention (T1). Exercisers were also investigated 4 weeks (T2) and 12 weeks (T3) after the intervention. Participants in the exercise condition showed a larger decrease in two of the three indicators of study-related fatigue (i.e., overall fatigue and need for recovery) as compared to controls. Additionally, sleep quality and some indicators of cognitive functioning improved more among exercisers than among controls. No effects were found for self-efficacy, and physical fitness. The initial effects of the exercise intervention lasted at follow-up (T2 and T3). At 12-week follow up (T3), 80% of participants in the exercise condition still engaged in regular exercise, and further enhancements were seen for emotional exhaustion, overall fatigue, and sleep quality. These results underline the value of low-intensity exercise for university students with high levels of study-related fatigue. The follow-up effects that were found in this study imply that the intervention has the potential to promote regular exercise and accompanying beneficial effects in the longer run.

Eating disturbances continue to grow among college students, and researchers have begun to investigate factors that may lead to abnormal eating behaviors in this population. Recent research has also suggested that excessive exercise can become a compulsive behavior that may affect psychological health. The aim of this exploratory study was to evaluate the relationships between both compulsive eating and exercise, and demographic and clinical variables in a college population. Participants were 589 undergraduates (mean age 20 years) recruited during a mental health screening at two different campuses. Participants completed a screening package of measures including a questionnaire about socio-demographic data, the Beck Depression Inventory (BDI), the Beck Hopelessness Scale (BHS), the Consumptive Habits Questionnaire (CHQ), the Modified Overt Aggression Scale-Self-rated version (MOAS), and the Quality of Life Enjoyment and Satisfaction Questionnaire-Short version (QLESQ). A prevalence rate of 7.2% was found for compulsive eating and 18.1% for compulsive exercise, as measured by the CHQ. Only 11 participants (1.9%) reported both compulsive eating and exercise. There was no significant relationship between compulsive eating and compulsive exercise. The results suggest that college students may represent a group at high risk of developing abnormal eating behaviors and compulsive exercise.

Muscular adaptations linked to a high volume and intensity of training have been scarcely reported. We aimed at documenting, using MRI, the cross-sectional area changes associated with a high volume and intensity of training in 11 thigh muscles of a population of professional road cyclists as compared with sport science students. We were also interested in determining, whether selective muscle hypertrophy in professional road cyclists, if any, was correlated to selective exercise-induced T (2) changes during a pedaling exercise on a cycloergometer. Cross-sectional area of 11 thigh muscles was quantified in sixteen subjects (i.e. eight professional road cyclists and eight sport science students) using MRI. In addition, transverse relaxation times (T (2)) were measured before and just after a maximal standardized constant-load exercise in order to investigate exercise-related T (2) changes in these muscles. Professional road cyclists had a significantly higher relative amount of muscle (including the whole set of thigh muscles, 90.5+/-3.3%) as compared to controls (81.6+/-7.3%). Regarding relative values expressed with respect to the total thigh muscles CSA, Vastus lateralis and Biceps femoris CSA were significantly larger in cyclists whereas CSA of the Vastus intermedius was smaller. However, this selective hypertrophy was not correlated to the exercise-induced T (2)-increase. We have reported, for the first time, a selective hypertrophy of Vastus lateralis and Biceps femoris in professional road cyclists confirming their involvement in pedaling task and suggesting a possible cause-effect relationship between muscle activation and hypertrophy, associated with a specific pedaling skill.

Wolf, Megan R; Rosenstock, Jason B

2017-04-01

The authors studied whether low levels of exercise or inadequate sleep correlated with higher levels of burnout and depression in medical students. Medical students of all years at the University of Pittsburgh School of Medicine, Pittsburgh, PA, USA, were invited to participate in an anonymous online survey in Fall 2012 and Winter 2013. Validated measures were used to assess exercise, sleep, burnout, and depression. Response rates were 28.7 % at the beginning of the school year and 22.6 % at the middle of the school year. Burnout rates overall were 22.4 % at the beginning of the year and 19.2 % in the middle of the year. Eight percent of students screened positive for depression at the beginning of the year and 9.3 % in the middle of the year. Decreased exercise frequency was significantly correlated with lower professional efficacy. Pathological sleepiness was significantly associated with a higher prevalence of burnout. Inadequate sleep correlated with significantly lower professional efficacy and higher exhaustion scores. Burnout was associated with a positive depression screen. Positive depression screening, pathological sleepiness, and sleeping less than 7 h a night were independent predictors of burnout. Sleep habits, exercise, and a positive depression screen were associated with burnout risk within the medical student population.

With the purpose of determining the prevalence of vitamin consumption, a survey was conducted in a sample of 894 private university freshmen in São Paulo. It revealed that 30.4% of the students consumed vitamin supplements within the preceding 3 months -23.1% on a regular basis and 6.0% sporadically. Vitamin C and multivitamin supplements were the most consumed products. The regular consumption of vitamin supplements was related to the frequency of physical exercises. "To stay healthy" was the most cited reason for supplementation.

Using simple manipulatives to improve student comprehension of a complex biological process: protein synthesis.

PubMed

Guzman, Karen; Bartlett, John

2012-01-01

Biological systems and living processes involve a complex interplay of biochemicals and macromolecular structures that can be challenging for undergraduate students to comprehend and, thus, misconceptions abound. Protein synthesis, or translation, is an example of a biological process for which students often hold many misconceptions. This article describes an exercise that was developed to illustrate the process of translation using simple objects to represent complex molecules. Animations, 3D physical models, computer simulations, laboratory experiments and classroom lectures are also used to reinforce the students' understanding of translation, but by focusing on the simple manipulatives in this exercise, students are better able to visualize concepts that can elude them when using the other methods. The translation exercise is described along with suggestions for background material, questions used to evaluate student comprehension and tips for using the manipulatives to identify common misconceptions.

Henige, Kim

2012-09-01

Physiology is often considered a challenging course for students. It is up to teachers to structure courses and create learning opportunities that will increase the chance of student success. In an undergraduate exercise physiology course, concept maps are assigned to help students actively process and organize information into manageable and meaningful chunks and to teach them to recognize the patterns and regularities of physiology. Students are first introduced to concept mapping with a commonly relatable nonphysiology concept and are then assigned a series of maps that become more and more complex. Students map the acute response to a drop in blood pressure, the causes of the acute increase in stroke volume during cardiorespiratory exercise, and the factors contributing to an increase in maximal O(2) consumption with cardiorespiratory endurance training. In the process, students draw the integrative nature of physiology, identify causal relationships, and learn about general models and core principles of physiology.

People use their smartphones for everything from web browsing to tracking fitness metrics. However, it is unclear whether smartphone-based apps that use photoplethysmography to measure heart rate are an accurate or valid measure of exercise intensity. Purpose was to determine the accuracy and validity of two iOS-based heart rate monitors, Runtastic Heart Rate Monitor and Pulse Tracker PRO by Runtastic (Runtastic) and Instant Heart Rate+: Heart Rate and Pulse Monitor by Azumio (Instant Heart Rate), when compared to the electrocardiogram (ECG) and Polar® T31 uncoded heart rate monitor from moderate to vigorous intensity exercise. Participants were 15 male and female regularly active college students. Pre-exercise heart rate and blood pressure were recorded and then participants exercised on a stationary bike at a pedal rate of between 50-60 rpms. After completing a warm-up stage at 40% of age estimated maximum heart rate (AEMHR), exercise intensity progressed from 50% of AEMHR through to 85% of AEMHR in eight, 5-minute stages. At the end of each stage, and having achieved steady-state, heart rates were recorded from each apparatus. After completing the final stage, participants completed a cooldown at 40% of their AEMHR. Post-exercise heart rate and blood pressure were also recorded to ensure full recovery to baseline. There was a strong positive correlation between the Polar® monitor and the ECG during all stages. However, there were not strong correlations for either of the smartphone-based apps at any time point. Although there were weak correlations between the smartphone-based apps and ECG and Polar®, further studies need to be conducted to determine if inaccuracy is due to user error (finger placement, finger temperature, etc.) or the technology behind the apps.

2017-07-01

Thirty students (mean age = 18 ± 0.5 years) completed self-report (Self-Control Scale) and objective (isometric handgrip squeeze performance) measures of self-control, provided their exercise and academic (study/schoolwork) plans for the next month, and then logged these behaviors over the subsequent 4-week period. Trait self-control predicted exercise and academic behavior. Handgrip squeeze performance predicted academic behavior and adherence to academic plans. Further, regression analysis revealed that trait self-control and handgrip performance explained significant variance in academic behavior. These findings provide a new understanding of how different self-control measures can be used to predict first-year students' participation in, and adherence to, exercise and academic behaviors concurrently.

Attentional bias to emotional stimuli is altered during moderate- but not high-intensity exercise.

PubMed

Tian, Qu; Smith, J Carson

2011-12-01

Little is known regarding how attention to emotional stimuli is affected during simultaneously performed exercise. Attentional biases to emotional face stimuli were assessed in 34 college students (17 women) using the dot-probe task during counterbalanced conditions of moderate- (heart rate at 45% peak oxygen consumption) and high-intensity exercise (heart rate at 80% peak oxygen consumption) compared with seated rest. The dot-probe task consisted of 1 emotional face (pleasant or unpleasant) paired with a neutral face for 1,000 ms; 256 trials (128 trials for each valence) were presented during each condition. Each condition lasted approximately 10 min. Participants were instructed to perform each trial of the dot-probe task as quickly and accurately as possible during the exercise and rest conditions. During moderate-intensity exercise, participants exhibited significantly greater attentional bias scores to pleasant compared with unpleasant faces (p < .01), whereas attentional bias scores to emotional faces did not differ at rest or during high-intensity exercise (p > .05). In addition, the attentional bias to unpleasant faces was significantly reduced during moderate-intensity exercise compared with that during rest (p < .05). These results provide behavioral evidence that during exercise at a moderate intensity, there is a shift in attention allocation toward pleasant emotional stimuli and away from unpleasant emotional stimuli. Future work is needed to determine whether acute exercise may be an effective treatment approach to reduce negative bias or enhance positive bias in individuals diagnosed with mood or anxiety disorders, or whether attentional bias during exercise predicts adherence to exercise.

León-Rodríguez, Julie C; Cañón-Betancourt, Lorena A

2013-01-01

Determining the effect of a prescribed unsupervised exercise and counseling program on the physical activity and fitness levels of university students volunteering for an emergency response brigade. Forty-two brigade volunteers engaged in a 12-week prescribed non-supervised exercise program. Body weight, body mass index (BMI), percentage body fat, waist circumference, oxygen consumption, flexibility and arms and abdomen strength endurance were assessed before and after performing the exercise program. The other variables measured concerned the level of physical activity during leisure time (days and minutes per week) and/or the use of alternative means of transport. Exercise was prescribed according to international standards. The activities, commitment and health-nutritional recommendations were controlled every two weeks. The study reported a statistically significant increase regarding the following variables: O2 consumption (from 46.41 ± 6.65 ml/Kg/min to 47.70 ± 6.27 ml/Kg/min; p<0.01), increased arm strength endurance (from 11.82 ± 9.97 to 14.74 ± 12.74 repetitions; p<0.01) and an increase in the number of abdominal exercises (crunches) (from 21.16 ± 11.91 to 26.64 ± 17.03 repeats; p<0.01). The real accomplishment regarding commitment by the time of the second measurement concerned 2.54 ± 2.07 days/week and 144.16 ± 238.89 minutes/week of physical activity. These levels were significantly lower than those established at the beginning of the program (4 ± 1.05 days/week and 239.52 ± 73.01 minutes/week; p<0.01). The prescribed unsupervised exercise and counseling program led to increases in oxygen consumption, arm strength endurance and the number of repeat abdominal crunches. Real fulfilment of the proposed activities was lower than planned original commitment.

EARTHTIME: Teaching geochronology to high school students

2010-05-01

The authors taught an educational module developed as part of the EARTHTIME (www.earth-time.org) outreach initiative to 215 high school students from a Massachusetts (USA) High School as part of an "out-of-school" field trip. The workshop focuses on uranium-lead (U-Pb) dating of zircons and its application to solving a geological problem. The theme of our 2.5-hour module is the timing of the K-T boundary and a discussion of how geochronology can be used to evaluate the two main hypotheses for the cause of the concurrent extinction—the Chicxlub impact and the massive eruption of the Deccan Traps. Activities are divided into three parts: In the first part, the instructors lead hands-on activities demonstrating how rock samples are processed to isolate minerals by their physical properties. Students use different techniques, such as magnetic separation, density separation using non-toxic heavy liquids, and mineral identification with a microscope. We cover all the steps from sampling an outcrop to determining a final age. Students also discuss geologic features relevant to the K-T boundary problem and get the chance to examine basalts, impact melts and meteorites. In the second part, we use a curriculum developed for and available on the EARTHTIME website (http://www.earth-time.org/Lesson_Plan.pdf). The curriculum teaches the science behind uranium-lead dating using tables, graphs, and a geochronology kit. In this module, the students start by exploring the concepts of half-life and exponential decay and graphically solving the isotopic decay equation. Manipulating groups of double-sided chips labeled with U and Pb isotopes reinforces the concept that an age determination depends on the Pb/U ratio, not the absolute number of atoms present. Next, the technique's accuracy despite loss of parent and daughter atoms during analysis, as well as the use of isotopic ratios rather than absolute abundances, is explained with an activity on isotope dilution. Here the students determine the number of beads in a large bucket without counting them all by adding a precisely known number of "tracer" beads and averaging ratios from several small samples of the mixture. The (pre-counted) unknown quantity of beads represents the isotopic composition of zircon from four samples—the Deccan Trap basalts, the Chicxulub impact melt, and ash layers above and below the K-T boundary —and the students' measurements are used in the final part of the module. An introduction to statistical inference from small samples can also be added to this exercise. After this, the chemistry and physics behind geochemical laboratory techniques, ion exchange chromatography and isotope ratio measurements using a mass spectrometer, are explained using models, movies, posters, and analogies to familiar physics. In the final part, students engage in a summary exercise where they apply what they have learned to test the two competing hypotheses. Using the dates they calculated with isotope dilution and a graphical solution to the decay equation, they determine if the Chicxulub impact or the Deccan Trap volcanic eruption can explain the K/T boundary mass extinction. They learn the importance of measurement uncertainty in interpreting data and brainstorm how best to resolve this outstanding scientific problem. Feedback from written evaluations shows that teachers valued the interdisciplinary association of concepts from physics, chemistry and mathematics. Students enjoyed the hands-on exercises that gave them the opportunity to see how rocks can be broken down into mineral separates and individual zircons selected for analysis. The K/T-boundary exercise at the end was appreciated because it demonstrates an exciting application of geochronological methods to popular science.

For second year medical students, we redesigned an original laboratory experiment and developed a combined research-teaching clinical biochemistry experiment. Using an established diabetic rat model to detect blood glucose and triglycerides, the students participate in the entire experimental process, which is not normally experienced during a standard clinical biochemistry exercise. The students are not only exposed to techniques and equipment but are also inspired to think more about the biochemical mechanisms of diseases. When linked with lecture topics about the metabolism of carbohydrates and lipids, the students obtain a better understanding of the relevance of abnormal metabolism in relation to diseases. Such understanding provides a solid foundation for the medical students' future research and for other clinical applications. © 2014 Biochemistry and Molecular Biology Education.

2010-01-01

Active learning exercises were developed to allow advanced medical students to revisit and review anatomy in a clinically meaningful context. In our curriculum, students learn anatomy two to three years before they participate in the radiology clerkship. These educational exercises are designed to review anatomy content while highlighting its relevance to the study of radiology. Laboratory exercises were developed using inexpensive materials in the form of hands-on stations designed for use by students working together in small groups. Station exercises include model building, exploring relevant radiological imaging, and practicing clinical techniques. Students are encouraged to move from abstract conceptualization of the anatomy using models to applying knowledge to living tissues by using a portable ultrasound to explore superficial anatomy on each other. Stations are designed to integrate knowledge and reemphasize concepts in different contexts, so that upon completion students have a reinforced understanding of the three-dimensional anatomy of the region in question, the appearance of the anatomy on radiological images, and an appreciation of the relevance of the anatomy to radiological procedures.

Challenging Students' Intuitions—the Influence of a Tangible Model of Virus Assembly on Students' Conceptual Reasoning About the Process of Self-Assembly

Larsson, Caroline; Tibell, Lena A. E.

2015-10-01

A well-ordered biological complex can be formed by the random motion of its components, i.e. self-assemble. This is a concept that incorporates issues that may contradict students' everyday experiences and intuitions. In previous studies, we have shown that a tangible model of virus self-assembly, used in a group exercise, helps students to grasp the process of self-assembly and in particular the facet "random molecular collision". The present study investigates how and why the model and the group exercise facilitate students' learning of this particular facet. The data analysed consist of audio recordings of six group exercises ( n = 35 university students) and individual semi-structured interviews ( n = 5 university students). The analysis is based on constructivist perspectives of learning, a combination of conceptual change theory and learning with external representations. Qualitative analysis indicates that perceived counterintuitive aspects of the process created a cognitive conflict within learners. The tangible model used in the group exercises facilitated a conceptual change in their understanding of the process. In particular, the tangible model appeared to provide cues and possible explanations and functioned as an "eye-opener" and a "thinking tool". Lastly, the results show signs of emotions also being important elements for successful accommodation.

Strain Analysis of Stretched Tourmaline Crystals Using ImageJ, Microsoft Excel and PowerPoint

NASA Astrophysics Data System (ADS)

Bosbyshell, H.

2012-12-01

This poster describes an undergraduate structural geology lab exercise utilizing the Mohr's circle diagram for finite strain, constructed using measurements obtained from stretched tourmaline crystals. A small building housing HVAC equipment at the south end of West Chester University's Recitation Hall (itself made of serpentinite) is constructed of early-Cambrian Chickies Quartzite. Stretched tourmaline crystals, with segments joined by fibrous quartz, are visible on many surfaces (presumably originally bedding). While the original orientation of any stone is unknown, these rocks provide an opportunity for a short field exercise during a two-hour lab period and a great base for conducting strain analysis. It is always fun to ask how many in the class have ever noticed the tourmaline (few have). Students take photos using their cell phones or cameras. Since strain is a ratio the absolute size of the tourmaline crystals is immaterial. Nonetheless, this is a good opportunity to remind students of the importance of including a scale in their photographs. The photos are opened in ImageJ and the line tool is used to determine the original and final lengths of selected crystals. Students calculate strain parameters using Microsoft Excel. Then, we use Adobe Illustrator or the drafting capabilities of Microsoft PowerPoint 2010 to follow Ramsay and Huber's techniques using a Mohr's circle construction to determine the finite strain ellipse. If a stretching direction can be estimated, elongation of two crystals is all that is required to determine the strain ratio. If no stretching direction is apparent, three crystals are required for a more complicated analysis that allows for determination of the stretching direction, as well as the strain ratio.
