Hsu, Li-Ling; Hsieh, Suh-Ing

2011-11-01

This article is a report of a quasi-experimental study of the effects of blended modules on nursing students' learning of ethics course content. There is yet to be an empirically supported mix of strategies on which a working blended learning model can be built for nursing education. This was a two-group pretest and post-test quasi-experimental study in 2008 involving a total of 233 students. Two of the five clusters were designated the experimental group to experience a blended learning model, and the rest were designated the control group to be given classroom lectures only. The Case Analysis Attitude Scale, Case Analysis Self-Evaluation Scale, Blended Learning Satisfaction Scale, and Metacognition Scale were used in pretests and post-tests for the students to rate their own performance. In this study, the experimental group did not register significantly higher mean scores on the Case Analysis Attitude Scale at post-test and higher mean ranks on the Case Analysis Self-Evaluation Scale, the Blended Learning Satisfaction Scale, and the Metacognition Scale at post-test than the control group. Moreover, the experimental group registered significant progress in the mean ranks on the Case Analysis Self-Evaluation Scale and the Metacognition Scale from pretest to post-test. No between-subjects effects of four scales at post-test were found. Newly developed course modules, be it blended learning or a combination of traditional and innovative components, should be tested repeatedly for effectiveness and popularity for the purpose of facilitating the ultimate creation of a most effective course module for nursing education. © 2011 Blackwell Publishing Ltd.

Quasi experimental designs in pharmacist intervention research.

PubMed

Krass, Ines

2016-06-01

Background In the field of pharmacist intervention research it is often difficult to conform to the rigorous requirements of the "true experimental" models, especially the requirement of randomization. When randomization is not feasible, a practice based researcher can choose from a range of "quasi-experimental designs" i.e., non-randomised and at time non controlled. Objective The aim of this article was to provide an overview of quasi-experimental designs, discuss their strengths and weaknesses and to investigate their application in pharmacist intervention research over the previous decade. Results In the literature quasi experimental studies may be classified into five broad categories: quasi-experimental design without control groups; quasi-experimental design that use control groups with no pre-test; quasi-experimental design that use control groups and pre-tests; interrupted time series and stepped wedge designs. Quasi-experimental study design has consistently featured in the evolution of pharmacist intervention research. The most commonly applied of all quasi experimental designs in the practice based research literature are the one group pre-post-test design and the non-equivalent control group design i.e., (untreated control group with dependent pre-tests and post-tests) and have been used to test the impact of pharmacist interventions in general medications management as well as in specific disease states. Conclusion Quasi experimental studies have a role to play as proof of concept, in the pilot phases of interventions when testing different intervention components, especially in complex interventions. They serve to develop an understanding of possible intervention effects: while in isolation they yield weak evidence of clinical efficacy, taken collectively, they help build a body of evidence in support of the value of pharmacist interventions across different practice settings and countries. However, when a traditional RCT is not feasible for logistical and/or ethical reasons researchers should endeavour to use the more robust of the quasi experimental designs.

Peer Assisted Learning Strategy for Improving Students’ Physiologic Literacy

NASA Astrophysics Data System (ADS)

Diana, S.

2017-09-01

Research about the implementation of the Peer Assisted Learning (PAL) strategy in Plant Physiology lecture has carried out, in which it aims to improve students’ physiologic literacy. The PAL strategy began with a briefing by the lecturers to the students tutor about pretest questions, followed by the interaction between student tutors with their peers to discuss response problems, terminated by answering responsiveness questions individually. This study used a quasi-experimental method, one - group pre-test post-test design. This design includes a group of students observed in the pre-test phase (tests carried out before PAL treatment) which is then followed by treatment with PAL and ends with post-test. The other students group (control) was given the pre-test and post-test only. The results showed that the PAL strategy can increase student’s physiologic literacy significantly. One of the weaknesses of students’ physiologic literacy is that they have not been able to read the graph. The faculties are encouraged to begin introducing and teaching material using a variety of strategies with scientific literacy aspects, for example teaching research-based material. All students respond positively to the PAL strategy.

PubMed

Dikec, Gul; Kutlu, Yasemin

2016-04-01

This study used a quasi-experimental design with a pretest-posttest control group and follow-up to determine the efficacy of adherence therapy in patients with schizophrenia in Turkey. The sample of this study consisted of patients with schizophrenia (n=30). The Questionnaire Form, Medication Adherence Rating Scale, Internalized Stigma of Mental Illness Scale, and Beck Cognitive Insight Scale were used. The patients were assigned to experimental (n=15) and control (n=15) groups using the randomization method. The experimental group received adherence therapy in eight sessions. When the scores of the patients in the experimental and control groups were compared at the pretest, posttest, and 3- and 6-months follow ups, a significant difference was only found in the Medication Adherence Rating Scale posttest scores. Adherence therapy is effective in improving adherence to treatment but is not effective with regard to insight and internalized stigma in patients with schizophrenia. Copyright © 2015 Elsevier Inc.

Madeni, Frida; Horiuchi, Shigeko; Iida, Mariko

2011-06-27

Sub-Saharan Africa is among the countries where 10% of girls become mothers by the age of 16 years old. The United Republic of Tanzania located in Sub-Saharan Africa is one country where teenage pregnancy is a problem facing adolescent girls. Adolescent pregnancy has been identified as one of the reasons for girls dropping out from school. This study's purpose was to evaluate a reproductive health awareness program for the improvement of reproductive health for adolescents in urban Tanzania. A quasi-experimental pre-test and post-test research design was conducted to evaluate adolescents' knowledge, attitude, and behavior about reproductive health before and after the program. Data were collected from students aged 11 to 16, at Ilala Municipal, Dar es Salaam, Tanzania. An anonymous 23-item questionnaire provided the data. The program was conducted using a picture drama, reproductive health materials and group discussion. In total, 313 questionnaires were distributed and 305 (97.4%) were useable for the final analysis. The mean age for girls was 12.5 years and 13.2 years for boys. A large minority of both girls (26.8%) and boys (41.4%) had experienced sex and among the girls who had experienced sex, 51.2% reported that it was by force. The girls' mean score in the knowledge pre-test was 5.9, and 6.8 in post-test, which increased significantly (t=7.9, p=0.000). The mean behavior pre-test score was 25.8 and post-test was 26.6, which showed a significant increase (t=3.0, p=0.003). The boys' mean score in the knowledge pre-test was 6.4 and 7.0 for the post-test, which increased significantly (t=4.5, p=0.000). The mean behavior pre-test score was 25.6 and 26.4 in post-test, which showed a significant increase (t=2.4, p=0.019). However, the pre-test and post-test attitude scores showed no statistically significant difference for either girls or boys. Teenagers have sexual experiences including sexual violence. Both of these phenomena are prevalent among school-going adolescents. The reproductive health program improved the students' knowledge and behavior about sexuality and decision-making after the program for both girls and boys. However, their attitudes about reproductive health were not likely to change based on the educational intervention as designed for this study.

PubMed

Nierkens, Vera; Kunst, Anton E; De Vries, Hein; Voorham, Toon A J; Stronks, Karien

2013-01-01

Community interventions have been considered promising strategies to reduce smoking prevalence among ethnic minority populations. We assessed the reach and effectiveness of a community program targeted at the Turkish population in Rotterdam, the Netherlands. The study had a quasi-experimental design, with 1 pretest and 1 posttest among 18- to 60-year-old Turkish residents in a district in Rotterdam (n = 388 at pretest) and in a comparison area in the city of Utrecht (n = 389 at pretest). The surveys included measures of reach and measures of effectiveness. Logistic regression analysis assessed changes in the outcome measures over time, adjusting for sex, age, and educational level. At posttest, more smokers (62.5%) perceived pros of quitting, and 8.2% had quit. Compared with the comparison group, in the intervention group the changes tended to be greater, but differences were not statistically significant. Of all respondents, 61.2% recognized at least 1 program component, and 23.1% participated in at least 1. Based on the greater changes in the intervention group (particularly regarding quit rates and pros of smoking), this community intervention can become a promising strategy. To increase potential effectiveness, participation rates need to increase and interventions should last longer and include smoking-cessation support.

The aim of this study was to investigate the effectiveness of the harm reduction group therapy based on Bandura's self-efficacy theory on risky behaviors of sex workers in Kerman, Iran. A quasi-experimental two-group design (a random selection with pre-test and post-test) was used. A risky behaviors questionnaire was used to collect. The sample was selected among sex workers referring to drop-in centers in Kerman. Subjects were allocated to two groups and were randomly classified into two experimental and control groups. The sample group consisted of 56 subjects. The experimental design was carried out during 12 sessions, and the post-test was performed one month and two weeks after the completion of the sessions. The results were analyzed statistically. By reducing harm based on Bandura's self-efficacy theory, the risky behaviors of the experimental group, including injection behavior, sexual behavior, violence, and damage to the skin, were significantly reduced in the pre-test compared to the post-test (P < 0.010). The harm reduction group therapy based on Bandura's self-efficacy theory can reduce the risky behaviors of sex workers.

This quasi-experimental research study used two similar nursing units to test the effects of teach back on Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) scores. A pretest-posttest design tested 24 nurses' knowledge, attitudes, and beliefs about teach back. Education specialists provided a 1-hour teaching session on teach back to all nurses in the intervention unit. A significant improvement in knowledge scores in the pretest-posttest was found using paired t tests (p = .002). Qualitative analysis of nurses' comments demonstrated strong support for teach back in the post-test. The HCAHPS scores were not significantly improved in the intervention unit when compared with the control unit. More research needs to be conducted to determine the effectiveness of teach back on HCAHPS scores. J Contin Educ Nurs. 2017;48(1):47-52. Copyright 2017, SLACK Incorporated.

This study aims to examine the effect of Science, Technology, Engineering, and Mathematics (STEM) based e-book in promoting students'conceptual understanding on lever system in human body. The E-book used was the e-book published by National Ministry of Science Education. The research was conducted by a quasi experimental with pretest and posttest design. The subjects consist of two classes of 8th grade junior high school in Pangkalpinang, Indonesia, which were devided into experimental group (n=34) and control group (n=32). The students in experimental group was taught by STEM-based e-book, while the control group learned by non STEM-based e-book. The data was collected by an instrument pretest and postest. Pretest and posttest scored, thenanalyzed using descriptive statistics and independent t-test. The result of independent sample t-test shows that no significant differenceson students' pretest score between control and experimental group. However, there were significant differences on students posttest score and N-gain score between control and experimental group with sig = 0.000(p<0.005). N-gain analysis showsthe higher performance of students who were participated in experimental group (mean = 66.03) higher compared to control group (mean = 47.66) in answering conceptual understanding questions. Based on the results, it can be concluded that STEM-based e-book has positiveimpact in promoting students' understanding on lever system in human body. Therefore this learning approach is potential to be used as an alternative to triger the enhancement of students' understanding in science.

The study followed a pretest-posttest quasi-experimental research design. A total of 92 students (aged 19-20 years), in a second-year undergraduate program, participated in this 18-week-long experiment. The students were divided into an experimental group and a control group. The experimental group (36 males and 10 females) was instructed utilizing the HIC system, while the control group (34 males and 12 females) was led through traditional teaching methods. Pretest, posttest, and delayed posttest scores were evaluated by multivariate analysis of covariance. The results indicated that participants in the experimental group who used the HIC system outperformed the control group, in the both posttest and delayed posttest, across three learning dimensions. Based on these results, the HIC system is recommended to be incorporated in formal materials science learning settings.

Impacts of Professional Development in Integrated STEM Education on Teacher Self-Efficacy, Outcome Expectancy, and Stem Career Awareness

NASA Astrophysics Data System (ADS)

Knowles, J. Geoff

This research analyzed the effects of teacher professional development and lesson implementation in integrated Science, Technology, Engineering, and Math (STEM) on: 1.) Teacher self-efficacy and their confidence to teach specific STEM subjects; 2.) Teaching outcome expectancy beliefs concerning the impact of actions by teachers on student learning; and 3.) Teacher awareness of STEM careers. High school science and technology education teachers participating in the Teachers and Researchers Advancing Integrated Lessons in STEM (TRAILS) project experimental group attended a ten-day summer professional development institute designed to educate teachers in using an integrated STEM education model to implement integrated STEM lessons. The research design utilized a quasi-experimental nonequivalent comparison group design that incorporated an experimental group and an untreated comparison group with both pretest, posttest, and delayed posttest assessments on non-randomized participants. Teacher self-efficacy has been identified as a key factor in effective teaching and student learning, and teacher awareness of STEM careers impacts students as they consider career choices. The T-STEM Survey for teachers was given for the pretest and posttest assessments to measure attitudes and beliefs toward the specific constructs of this study. Significant effects of the TRAILS professional development were found in the teacher group (experimental or comparison) and teacher subject (technology or science) in pretest and posttest scores using cumulative link models for the constructs of teacher self-efficacy and beliefs to teach STEM subjects, teacher outcome expectancy beliefs, and teacher awareness of STEM careers. Effect sizes ranged from small to large varying by construct and assessment time. Highly significant p-values and effect sizes revealed impacts on science teachers were greater when teacher subject groups were analyzed separately.
The effect of constructivist teaching strategies on science test scores of middle school students

NASA Astrophysics Data System (ADS)

Vaca, James L., Jr.

International studies show that the United States is lagging behind other industrialized countries in science proficiency. The studies revealed how American students showed little significant gain on standardized tests in science between 1995 and 2005. Little information is available regarding how reform in American teaching strategies in science could improve student performance on standardized testing. The purpose of this quasi-experimental quantitative study using a pretest/posttest control group design was to examine how the use of a hands-on, constructivist teaching approach with low achieving eighth grade science students affected student achievement on the 2007 Ohio Eighth Grade Science Achievement Test posttest (N = 76). The research question asked how using constructivist teaching strategies in the science classroom affected student performance on standardized tests. Two independent samples of 38 students each consisting of low achieving science students as identified by seventh grade science scores and scores on the Ohio Eighth Grade Science Half-Length Practice Test pretest were used. Four comparisons were made between the control group receiving traditional classroom instruction and the experimental group receiving constructivist instruction including: (a) pretest/posttest standard comparison, (b) comparison of the number of students who passed the posttest, (c) comparison of the six standards covered on the posttest, (d) posttest's sample means comparison. A Mann-Whitney U Test revealed that there was no significant difference between the independent sample distributions for the control group and the experimental group. These findings contribute to positive social change by investigating science teaching strategies that could be used in eighth grade science classes to improve student achievement in science.

Diana, S.

2018-05-01

Research about the effect of Peer Assisted Learning (PAL) strategy on Plant Anatomy Course, which aims to improve anatomic competencies of prospective student’s biology teacher, has been done. This study used a quasi-experimental pre-test post-test control group design. The draft includes a group of students who were given a pre-test which is then followed by observing the PAL treatment process and post-test. The other students group (control) was given the pre-test and post-test only. The PAL program began with a discussion between the lecturer and the tutor about the pretest results and then discussion between the tutors and their tutees in the class about the responses items. After that, all students were assigned to answer a set of response items, and then did the posttest. The results showed that the PAL strategy can increase student’s anatomic literacy significantly and can increase student’s anatomic lab skills no significantly. Thus the PAL strategy implementation has a potential to improve student’s anatomic competencies. The generally students weaknesses were they lack practice in interpreting of research results in the graphs form and rarely shared about anatomic lab skills. All students respond positively to the PAL strategy.

Caregivers who work in community living arrangements or intermediate care facilities are responsible for the oral hygiene of individuals with intellectual and developmental disabilities. Oral hygiene training programs do not exist in many organizations, despite concerns about the oral care of this population. The purpose of this study was to determine the effectiveness of a caregiver educational program. This study used a quasi-experimental one-group pretest/posttest design with repeated measures to describe the outcomes of an educational program. Program participants demonstrated oral hygiene skills on each other while being scored by a trained observer, after which they completed an oral hygiene compliance survey. After three months, a follow-up included the same posttest, demonstration of oral hygiene skills, and repeat of the compliance survey. Paired-sample t-tests of oral hygiene knowledge showed a statistically significant improvement from pretest to posttest and from pretest to three-month posttest. Oral hygiene skills and compliance improved. Results demonstrate evidence that caregiver education improves knowledge, skill, and compliance in oral hygiene. Further studies are required to demonstrate the value of providing oral hygiene education and training for caregivers of individuals with intellectual and developmental disabilities.

Youths in Jordan lack knowledge related to reproductive health (RH). Interactive teaching methods showed positive results in enhancing health awareness and adopting healthy practices among students. The objective of this study was to examine the usefulness of interactive teaching in promoting health awareness of RH among nonmedical university students in Jordan. We employed a quasi-experimental one group pretest and posttest design for a purposive sample of 210 students (18-24 years). Knowledge and attitudes regarding RH issues were assessed using a questionnaire developed by the researchers. A significant improvement in students' knowledge and attitudes toward RH was evident. Female students had higher scores on knowledge than male students in the pretest; this difference was smaller in the posttest. Also, female students had significantly more positive attitudes toward RH in pretest than males, although this difference vanished in the posttest. Study results indicated that students benefit from study intervention regardless their gender. Integrating RH into university's curriculum coupled with interactive learning approach is a powerful way to promote RH awareness among youths.

Interprofessional education is intended to train practitioners to collaboratively address challenges in healthcare delivery, and interprofessional simulation-based education (IPSE) provides realistic, contextual learning experiences in which roles, responsibilities, and professional identity can be learned, developed, and assessed. Reducing negative stereotypes within interprofessional relationships is a prime target for IPSE. We sought to understand whether perceptions of interprofessional education and provider stereotypes change among nursing and medical students after participating in IPSE. We also sought to determine whether changes differed based on the student's discipline. This was a quasi-experimental pretest-posttest study. The study took place at a large mid-Atlantic public university with a comprehensive health science campus. 147 senior Bachelors of Science in Nursing students and 163 fourth-year medical students participated. Students were grouped into interprofessional teams for a two-week period and participated in three two-hour simulations focused on collaboration around acutely ill patients. At the beginning of the first session, they completed a pretest survey with demographic items and measures of their perceptions of interprofessional clinical education, stereotypes about doctors, and stereotypes about nurses. They completed a posttest with the same measures after the third session. 251 students completed both the pretest and posttest surveys. On all three measures, students showed an overall increase in scores after the IPSE experience. In comparing the change by student discipline, medical students showed little change from pretest to posttest on stereotypes of doctors, while nursing students had a significant increase in positive perceptions about doctors. No differences were noted between disciplines on changes in stereotypes of nurses. This study demonstrated that a short series of IPSE experiences resulted in improved perceptions of interprofessional practice and changes in stereotypical views of each profession even when the experience was not directly designed to address these issues. Differences observed between nursing and medical students should be explored further. Copyright © 2017 Elsevier Ltd. All rights reserved.

Hypertension is known to have high rates among Chinese Americans. Identifying culturally specific interventions to reduce sedentary behavior may be effective in reducing hypertension. This study examines the effects of an 8-week walking program with and without cultural modification. The study used a 2-group, pretest and posttest, quasi-experimental design. A total sample of 128 Chinese American immigrants with hypertension were assigned to walking groups. The results showed that the walking program had no significant effects upon participant blood pressure or walking endurance. The results also revealed that individuals in the maintenance stage walked longer than those in the preparation stage. A comparison of demographic data showed that subjects with a lower level of education walked more minutes per week, which contributed to lower systolic blood pressures among this group as compared with those with a higher level of education. These results suggest that this walking protocol, when translated into Chinese and when accompanied by a weekly telephone reminder and other interactions with a Chinese-speaking nurse, is appropriate to use without additional cultural modification. Future research should examine other components of Chinese culture or should apply this protocol for a longer period of time.

To develop and evaluate the long-term effectiveness of an intervention program, based on preaction-stage-oriented change processes of the Transtheoretical Model of Behavior Change, that could be delivered in a group setting to help participants lower dietary fat intake. An enhanced version of the nonequivalent control group experimental design was used. Entire sections of an undergraduate introductory nutrition science course were assigned to an experimental, pretest/posttest control, or posttest-only control group. Daily fat intake and stage of change of the experimental and pretest/posttest control groups were determined at the pretest and posttest and 1-year later at a follow-up test. Every 1 to 2 weeks during the study, stage of change of the experimental group was assessed. Daily fat intake of the experimental group was assessed at study midpoint. Daily fat intake and stage of change of the posttest-only control group was determined at the posttest. Pretest results were used to place participants of the experimental and pretest/posttest control groups in either the preaction stage (i.e., precontemplation, contemplation, or preparation) or the action/maintenance stage. The sample consisted of 38, 30, and 42 undergraduate students who were assigned to the experimental, pretest/posttest control, and posttest-only control groups, respectively. The experimental group participated in a group-based, dietary fat intake intervention that included a series of 11 lessons taught over a 14-week period. Each lesson was based on 1 or 2 of the preaction-stage-oriented change processes of the Transtheoretical Model. Data were evaluated to determine the effects of the intervention program on long-term dietary fat reduction and stage of change progression. Analysis of variance, repeated-measures analysis of variance, and paired t tests. For pretest and posttest dietary fat intake scores, stage and time were significant, and there was a significant time-by-stage interaction. Time was significant for pretest and posttest stage scores. Subjects in the preaction-stage experimental group significantly increased their mean stage of change and reduced their fat intake between the pretest and posttest; these changes persisted for 1 year. Pretest/posttest control group participants who began in a preaction stage also significantly increased their mean stage and reduced fat intake by the posttest, but these changes did not endure until the follow-up test. This intervention program produced an enduring, significant reduction in mean dietary fat consumption and a significant progression in mean stage of change of subjects in the experimental group who were in the preaction stage. It may be appropriate to design group interventions to use preaction stage processes rather than the more traditionally used action and maintenance stages change processes.

In-service education affects the quality of cancer care directly. Using classroom teaching to deliver in-service education is often ineffective due to participants' large workload and shift requirements. This study evaluated the learning effectiveness of different teaching methods in the dimensions of knowledge, attitude, and learning satisfaction. This study used a quasi-experimental study design. Participants were cancer ward nurses working at one medical center in northern Taiwan. Participants were divided into an experimental group and control group. The experimental group took an e-learning course and the control group took a standard classroom course using the same basic course material. Researchers evaluated the learning efficacy of each group using a questionnaire based on the quality of cancer nursing care learning effectiveness scale. All participants answered the questionnaire once before and once after completing the course. (1) Post-test "knowledge" scores for both groups were significantly higher than pre-test scores for both groups. Post-test "attitude" scores were significantly higher for the control group, while the experimental group reported no significant change. (2) after a covariance analysis of the pre-test scores for both groups, the post-test score for the experimental group was significantly lower than the control group in the knowledge dimension. Post-test scores did not differ significantly from pre-test scores for either group in the attitude dimension. (3) Post-test satisfaction scores between the two groups did not differ significantly with regard to teaching methods. The e-learning method, however, was demonstrated as more flexible than the classroom teaching method. Study results demonstrate the importance of employing a variety of teaching methods to instruct clinical nursing staff. We suggest that both classroom teaching and e-learning instruction methods be used to enhance the quality of cancer nursing care education programs. We also encourage that interactivity between student and instructor be incorporated into e-learning course designs to enhance effectiveness.

Data on adverse drug reactions (ADRs) showed a rising trend in the elderly over 65 years using multiple medications. To identify registered nurses' (RNs) knowledge of medication management and ADRs in the elderly in aged care facilities; evaluate an education programme to increase pharmacology knowledge and prevent ADRs in the elderly; and develop a learning programme with a view to extending provision, if successful. This exploratory study used a non-randomized pre- and post-test one group quasi-experimental design without comparators. It comprised a 23-item knowledge-based test questionnaire, one-hour teaching session and a self-directed learning package. The volunteer sample was RNs from residential aged care facilities, involved in medication management. Participants sat a pre-test immediately before the education, and post-test 4 weeks later (same questionnaire). Participants' perceptions obtained. Pre-test sample n = 58, post-test n = 40, attrition rate of 31%. Using Microsoft Excel 2000, descriptive statistical data analysis of overall pre- and post-test incorrect responses showed: pre-test proportion of incorrect responses = 0.40; post-test proportion of incorrect responses = 0.27; Z-test comparing pre- and post-tests scores of incorrect responses = 6.55 and one-sided P-value = 2.8E-11 (P < 0.001). Pre-test showed knowledge deficits in medication management and ADRs in the elderly; post-test showed statistically significant improvement in RNs' knowledge. It highlighted a need for continuing professional education. Further studies are required on a larger sample of RNs in other aged care facilities, and on the clinical impact of education by investigating nursing practice and elderly residents' outcomes.
Genetics instruction with history of science: Nature of science learning

2007-12-01

This study explored the effect of history of genetics in teaching genetics and learning the nature of science (NOS). A quasi-experimental control group research design with pretests, posttests, and delayed posttests was used, combining qualitative data and quantitative data. Two classes which consisted of tenth grade biology students participated in this study. The present study involved two instructional interventions, Best Practice Instruction with History of Genetics (BPIw/HG) and Best Practice Instruction (BPI). The experimental group received BPIw/HG utilizing various historical materials from the history of genetics, while the control group was not introduced to historical materials. Scientific Attitude Inventory II, Genetics Terms' Definitions with Concept Mapping (GTDCM), NOS Terms' Definitions with Concept Mapping (NTDCM), and View of Nature of Science (VNOS-C) were used to investigate students' scientific attitude inventory, and their understanding of genetics as well as the NOS. The results showed that students' scientific attitude inventory, and their understanding of genetics and the NOS were not statistically significantly different in the pretest (p>.05). After the intervention, the experimental group of students who received BPIw/HG demonstrated better understanding of the NOS. NTDCM results showed that the experimental group was better in defining the NOS terms and constructing a concept map ( p<.01). In addition, the experimental group retained their understanding of the NOS two-months after the completion of the intervention, showing no statistically significant difference between the posttest and the delayed posttest of NTDCM (p>.05). Further, VNOS-C data indicated that a greater percentage of the experimental group than the control group improved their understanding of the NOS. However, the two groups' understanding of genetics concepts did not show any statistically significant difference in the pretest, the posttest, and the delayed posttest (p>.05). This result implicated that allocating classroom time in introducing history of science neither helped nor hindered learning science content.

The Internet has emerged as an important tool for the delivery of health promotion and disease prevention interventions. Our community-based participatory research (CBPR) partnership developed and piloted CyBER/testing, a culturally congruent intervention designed to promote HIV testing among men who have sex with men (MSM) within existing Internet chat rooms. Using a quasi-experimental, single-group study design, cross-sectional data were collected from chat room participants, known as "chatters," at pretest (n = 346) and posttest (n = 315). Extant profile data also were collected to describe the demographics of the online population. The intervention significantly increased self-reported HIV testing among chatters overall, increasing rates from 44.5% at pretest to nearly 60% at posttest (p < .001). Furthermore, chatters who reported having both male and female sexual partners had nearly 6 times the odds of reporting HIV testing at posttest. Findings suggest that chat room-based HIV testing intervention may increase testing among MSM who may be difficult to reach in traditional physical spaces.

This study (1) explores the effectiveness of the contextualized history of science on student learning of nature of science (NOS) and genetics content knowledge (GCK), especially interrelationships among various genetics concepts, in high school biology classrooms; (2) provides an exemplar for teachers on how to utilize history of science in genetics instruction; and (3) suggests a modified concept mapping assessment tool for both NOS and GCK. A quasi-experimental control group research design was utilized with pretests, posttests, and delayed posttests, combining qualitative data and quantitative data. The experimental group was taught with historical curricular lessons, while the control group was taught with non-historical curricular lessons. The results indicated that students in the experimental group developed better understanding in targeted aspects of NOS immediately after the intervention and retained their learning 2 months after the intervention. Both groups developed similar genetics knowledge in the posttest, and revealed a slight decay in their understanding in the delayed posttest.

The purpose of this study was to identify the effects of the program to promote drinking knowledge, attitudes, and coping behavior in preschool children. A quasi-experimental with non-equivalent control group pretest-posttest design was conducted. The participants were 123 five year old children from G city. They were assigned to the experimental group (n=77) or the control group (n=46). A pretest and posttest were conducted to measure main variables. For the experimental group, the drinking prevention program was given for 6 weeks. Data were analyzed using χ²-test, t-test, and ANCOVA. After the intervention, preschool children in the experimental group reported significant differences in drinking knowledge (F=9.25, p=.003), drinking attitudes (F=19.57, p<.001), and coping behavior (F=16.38, p<.001) compared to preschool children in the control group. The results of this study indicate that a drinking prevention program for preschool children is effective in increasing drinking knowledge, attitudes, and coping behavior. This drinking prevention program is recommended as an effective intervention for preschool age children to postpone an early introduction to drinking.

This study was done to evaluate the Military Mental Health Promotion Program. The program was an email based cognitive behavioral intervention. The research design was a quasi-experimental study with a non-equivalent control group pretest-posttest design. Participants were 32 soldiers who agreed to participate in the program. Data were collected at three different times from January 2012 to March 2012; pre-test, post-test, and a one-month follow-up test. The data were statistically analyzed using SPSS 18.0. The effectiveness of the program was tested by repeated measures ANOVA. The first hypothesis that the level of depression in the experimental group who participated in the program would decrease compared to the control group was not supported in that the difference in group-time interaction was not statistically significant (F=2.19, p=.121). The second and third hypothesis related to anxiety and self-esteem were supported in group-time interaction, respectively (F=7.41, p=.001, F=11.67, p<.001). Results indicate that the program is effective in improving soldiers' mental health status in areas of anxiety and self-esteem.

2014-10-01

A pilot study of an interactive hazards education program was carried out in Canberra (Australia), with direct input from youth participants. Effects were evaluated in relation to youths' interest in disasters, motivation to prepare, risk awareness, knowledge indicators, perceived preparedness levels, planning and practice for emergencies, and fear and anxiety indicators. Parents also provided ratings, including of actual home-based preparedness activities. Using a single group pretest-posttest with benchmarking design, a sample of 20 youths and their parents from a low SES community participated. Findings indicated beneficial changes on a number of indicators. Preparedness indicators increased significantly from pre- to posttest on both youth (p < 0.01) and parent ratings (p < 0.01). Parent ratings reflected an increase of just under six home-based preparedness activities. Youth knowledge about disaster mitigation also was seen to increase significantly (p < 0.001), increasing 39% from pretest levels. While personalized risk perceptions significantly increased (p < 0.01), anxiety and worry levels were seen either not to change (generalized anxiety, p > 0.05) or to reduce between pre- and posttest (hazards-specific fears, worry, and distress, ps ranged from p < 0.05 to < 0.001). In terms of predictors of preparedness, a number of variables were found to predict posttest preparedness levels, including information searching done by participants between education sessions. These pilot findings are the first to reflect quasi-experimental outcomes for a youth hazards education program carried out in a setting other than a school that focused on a sample of youth from a low SES community. © 2014 Society for Risk Analysis.

Objective: To compare the knowledge and attitude regarding pubertal changes among pre - adolescent girls before and after the pubertal preparedness program (PPP) in experimental and comparison group. Materials and methods: A Quasi experimental (non- equivalent comparison group pretest posttest) design was adopted with 104pre-adolescentgirls (52 in each experimental and comparison group) of age 12-14years, selected by purposive sampling from two different Government schools of Ambala District. Knowledge and attitude was assessed using structured knowledge questionnaire (KR-20 = 0.74) and 5 point likert scale (Cronbach's alpha = 0.79) respectively. On the same day of pretest, PPP was administered and on 12 th day FAQs reinforcement session was held only for experimental group. After 28 days, posttest was taken. Results: The computed t value of pretest of knowledge and attitude scores of pre-adolescent girls (1.97), (1.95) respectively in experimental and comparison group was found non-significant at 0.05 level of significance which shows that both group didn't differ significantly in their knowledge and attitude before the administration of intervention. Findings of unpaired 't' value of posttest knowledge and attitude scores of pre-adolescent girls (19.77), (17.17) respectively in experimental and comparison group were found significant at 0.05 level of significance, Thus knowledge and attitude of pre-adolescent girls were improved with PPP and FAQs session. Conclusion: Pubertal preparedness program and FAQs reinforcement session are effective in enhancing knowledge and developing favorable attitude among pre-adolescent girls.

The purpose of this quasi-experimental, nonequivalent pretest-posttest control group design study was to determine if any differences existed in upper elementary school students' science academic achievement when instructed using an 8-week integrated science and English language arts literacy supplemental instructional intervention in conjunction with traditional science classroom instruction as compared to when instructed using solely traditional science classroom instruction. The targeted sample population consisted of fourth-grade students enrolled in a public elementary school located in the southeastern region of the United States. The convenience sample size consisted of 115 fourth-grade students enrolled in science classes. The pretest and posttest academic achievement data collected consisted of the science segment from the Spring 2015, and Spring 2016 state standardized assessments. Pretest and posttest academic achievement data were analyzed using an ANCOVA statistical procedure to test for differences, and the researcher reported the results of the statistical analysis. The results of the study show no significant difference in science academic achievement between treatment and control groups. An interpretation of the results and recommendations for future research were provided by the researcher upon completion of the statistical analysis.

Approximately a third of patients in neuroscience intensive care units (ICUs) experience subclinical seizures and, as a result, are at higher risk for poor outcomes. The use of continuous electroencephalography (cEEG) monitoring can help nurses detect seizure activity and initiate early prevention. Nurse competency in the use of cEEG is important to facilitate effective bedside monitoring. The objective of this study was to evaluate the effectiveness of a staff educational program aimed at improving the knowledge of nurses in the use of cEEG monitoring in adults. A quasi-experimental pretest/posttest 1-group design was utilized. Neuroscience ICU registered nurses, whose experience ranged from 2 months to 24 years, participated in the study. Participants completed a pretest on seizure knowledge and the use of cEEG monitoring. Participants received a 4-hour educational session on the use of cEEG monitoring. Immediately after the program and again 1 month later, they completed a posttest. Test scores improved significantly from pretest to the first posttest (t = -15.093, p < .001). Although there was a slight decline in the mean score from the posttest to the 1-month follow-up, posttest scores were significantly better than the pretest score (t = -12.42, df = 44, p < .001). Whereas years of experience correlated positively to the pretest score, after the intervention, no such correlation was evident. The results demonstrated that an educational program improved the competency of nurses in the use of cEEG with adult patients in a neuroscience ICU and that this knowledge was sustained over time. Further research is needed to demonstrate the effectiveness of this intervention in other settings.

Problem-based learning (PBL) has become a distinct approach in learning. To assess the effectiveness of PBL in teaching ethics to medical students and the effect it has on their ethical reasoning, we decided to hold a PBL ethics workshop and then evaluate them based on pretest and posttest. This quasi-experimental comparative study in Shiraz University of Medical Sciences was designed based on pretest-posttest nonequivalent groups. After obtaining their consent, 120 health care providers were randomly selected and assigned in 4 groups and then asked to attend the ethics workshop. For measuring the participants' ethical reasoning through pretesting and posttesting, a case study consisting of 21 multiple-choice questions (cognitive domain-apply level) was performed. Data were then collected using a questionnaire, which was completed by the participants and analyzed using SPSS software (version 17). The comparison between the participants' attitude and knowledge toward ethics before and after the workshop revealed that all indices in the cognitive domain were changed (P < .001). The scores of pretest and posttest were significantly different. As to the results of our study, the PBL groups showed a more positive learning attitude and higher motivation in comparison with the control group who were subjected to traditional-based method of learning. The result of our study suggests that PBL can and should be used as an alternative method in teaching ethics in medical students because it is more effective and motivates the students.

The purpose of this study was to investigate the effectiveness of the advance organiser model (AOM) on students' academic achievement in learning work and energy. The design of the study was quasi-experimental pretest-posttest nonequivalent control groups. The total population of the study was 139 students of three sections in Endabaguna preparatory school in Tigray Region, Ethiopia. Two sections with equivalent means on the pretest were taken to participate in the study purposely and one section assigned as the experimental group and the other section assigned as the control group randomly. The experimental group was taught using the lesson plan based on the AOM, and the control group was taught using the lesson plan based on the conventional teaching method. Pretest and posttest were administered before and after the treatment, respectively. Independent sample t-test was used to analyse the data at the probability level of 0.05. The findings of the study showed that the AOM was more effective than the conventional teaching method with effect size of 0.49. This model was also effective to teach male and female students and objectives namely understanding and application. However, both methods were equally important to teach work and energy under the objective knowledge level.

A naturally occurring quasi-experimental longitudinal field study of 87 municipal employees using pretest and posttest measures investigated the effects of an office workstation ergonomics intervention program on employees' perceptions of their workstation characteristics, levels of persistent pain, eyestrain, and workstation satisfaction. The study examined whether reactions differed between younger and older employees. Results revealed that workstation improvements were associated with enhanced perceptions of the workstation's ergonomic qualities, less upper back pain, and greater workstation satisfaction. Among those experiencing an improvement, the perceptions of workstation ergonomic qualities increased more for younger than older employees, supporting the "impressionable years" framework in the psychological literature on aging. Implications for human resources managers are discussed.

This study compared the effects of reading-oriented tasks and writing-oriented tasks on students' reading comprehension of geometry proof (RCGP). The reading-oriented tasks were designed with reading strategies and the idea of problem posing. The writing-oriented tasks were consistent with usual proof instruction for writing a proof and applying it. Twenty-two classes of ninth-grade students ( N = 683), aged 14 to 15 years, and 12 mathematics teachers participated in this quasi-experimental classroom study. While the experimental group was instructed to read and discuss the reading tasks in two 45-minute lessons, the control group was instructed to prove and apply the same propositions. Generalised estimating equation (GEE) method was used to compare the scores of the post-test and the delayed post-test with the pre-test scores as covariates. Results showed that the total scores of the delayed post-test of the experimental group were significantly higher than those of the control group. Furthermore, the scores of the experimental group on all facets of reading comprehension except the application facet were significantly higher than those of the control group for both the post-test and delayed post-test.

The Internet has emerged as an important tool for the delivery of health promotion and disease prevention interventions. Our community-based participatory research (CBPR) partnership developed and piloted CyBER/testing, a culturally congruent intervention designed to promote HIV testing among men who have sex with men (MSM) within existing Internet chat rooms. Using a quasi-experimental, single-group study design, cross-sectional data were collected from chat room participants, known as “chatters,” at pretest (n=346) and post-test (n=315). Extant profile data also were collected to describe the demographics of the online population. The intervention significantly increased self-reported HIV testing among chatters overall, increasing rates from 44.5% at pretest to nearly 60% at post-test (p<.001). Furthermore, chatters who reported having both male and female sexual partners had nearly 6 times the odds of reporting HIV testing at post-test. Findings suggest that chat room-based HIV testing intervention may increase testing among MSM who may be difficult to reach in traditional physical spaces. PMID:21393625

2011-01-01

Research by Huck and McLean (1975) demonstrated that the covariance-adjusted score is more powerful than the simple difference score, yet recent reviews indicate researchers are equally likely to use either score type in two-wave randomized experimental designs. A Monte Carlo simulation was conducted to examine the conditions under which the simple difference and covariance-adjusted scores were more or less powerful to detect treatment effects when relaxing certain assumptions made by Huck and McLean (1975). Four factors were manipulated in the design including sample size, normality of the pretest and posttest distributions, the correlation between pretest and posttest, and posttest variance. A 5 × 5 × 4 × 3 mostly crossed design was run with 1,000 replications per condition, resulting in 226,000 unique samples. The gain score was nearly as powerful as the covariance-adjusted score when pretest and posttest variances were equal, and as powerful in fan-spread growth conditions; thus, under certain circumstances the gain score could be used in two-wave randomized experimental designs.

The objective of this study is to determine the effect of yoga on functional recovery level in schizophrenic patients. The study was conducted in quasi-experimental design with pretest-posttest control group. The population of the study consisted of schizophrenic patients with registered in Malatya and Elazığ Community Mental Health Centers and regularly going to these centers. The sample group of the study consisted of totally 100 patients including 50 patients in the experimental group and 50 patients in the control group who were specified through power analysis and chosen by using random sampling method from this population. The data were collected between April 2015 and August 2015. 'Patient Description Form' and 'FROGS' were used to collect the data. Yoga was applied to patients in the experimental group. Any intervention was not made to patients in the control group. Percentage distribution, arithmetic mean, standard deviation, chi-square, independent samples t test, and paired t test were used to assess the data. Patients in the control and experimental group pretest subscale and the total means scores of FROGS was found to be low. In the posttest subscale and total means scores of FROGS in the experimental group were higher than in the control group and the differences between them were found to be statistically significant (p<0.05). In the experimental group pretest and posttest subscale and total means scores of FR0GS was determined to be statistically significant (p<0.05). Yoga that applied to schizophrenic patients it was determined to increased the level of functional recovery. It can be suggested that yoga should be used as an complementary method in nursing practise in order to increase the effectiveness of the treatment. Copyright Â© 2016 Elsevier Inc.

2011-02-01

To determine whether there was a difference in retention of knowledge about pressure ulcers with a traditional lecture versus computer-based instruction. A quasi-experimental, pretest/posttest design was used. Medical-surgical and critical care nurses (N = 60) were randomly assigned to a lecture, to computer-based instruction, or to a control group. Study participants were given the pressure ulcer knowledge test before and immediately after the program and at 3-month and 6-month intervals. Analysis of variance showed statistically significant differences in pretest and posttest scores [F(2, 57) = 35.784, p = .000] and in posttest to 3-month scores [F(2, 57) = 18.427, p = .000] among the three groups. The most significant loss of pressure ulcer knowledge, regardless of educational method, occurred within the first 3 months. Based on these findings, quarterly education in pressure ulcer prevention is recommended to maintain knowledge. Computer-based instruction is a viable option for acquisition and retention of knowledge about pressure ulcer prevention. Copyright 2011, SLACK Incorporated.

This study evaluated the short-term efficacy of brief cognitive behavioral therapy for reducing depression among Thai general hospital patients with alcohol dependence. A quasi-experimental design was used with a control group and pretest, posttest, and follow-up assessments. Participants were patients with alcohol dependence and depression who were recruited from district and provincial hospitals in northern Thailand. Eighty (N = 80) eligible participants were purposively selected and enrolled, and then randomly assigned into two groups. One group received three weeks of brief six-session cognitive behavioral therapy as the intervention, and the other group received usual care as their treatment. Data were collected at Week 0 (pretest), Week 3 (posttest), and Week 7 (one month follow-up) and included a nine-item depression scale, with analysis through descriptive statistics and t-test. Findings indicated that the mean depression scores decreased significantly (p < .01) in both the experimental (n = 33) and control groups (n = 27) at the one month follow-up (Week 7). However, only the experimental group showed significant differences in their mean depression scores between pre- and posttest. At Week 7, the experimental group showed significantly lower mean depression scores than the control group (p < .05). In summary, the brief six-session cognitive behavioral therapy intervention yielded promising results and may benefit patients with alcohol dependence and depression who are seen in general hospital settings.

Using inquiry-based instructional strategies in third-grade science

NASA Astrophysics Data System (ADS)

Harris, Fanicia D.

The purpose of the study was to determine if the use of inquiry-based instructional strategies as compared to traditional instructional strategies would increase third-grade students' achievement in science, based on the pretest/posttest of the school system and the Georgia Criterion-Referenced Competency Test (CRCT). Inquiry-based instruction, presented students with a question, an observation, a data set, or a hypothesis for problem solving such as scientists use when working in real-world situations. This descriptive research employed a quantitative strategy using a pretest/posttest control group design. The research compared the science academic achievement levels of one Grade 3 class [N=14] exposed to a teacher's inquiry-based instructional strategies as compared to one Grade 3 class [ N=18] exposed to a teacher's traditional instructional strategies. The study compared the science academic performance levels of third-grade students as measured by pretest/posttest mean scores from the school system-based assessment and the Georgia CRCT. Four research hypotheses were examined. Based on the overall findings from this study, both the experimental group and the control group significantly increased their mean scores from the pretests to the posttests. The amount of gain from the pretest to the posttest was significantly greater for the experimental group than the control group for pretest/posttest 1 [t(12) = 8.79, p < .01] and pretest/posttest 2 [t(12) = 9.40, p < .01]. The experimental group significantly outperformed the control group with regard to their mean number of items answered correctly on the life sciences test [t(27) = -1.95, p = .06]. Finally, the control group did not outperform the experimental group on any of the comparisons made throughout this study. The results of this study provide empirical support for the effectiveness of the use of inquiry-based learning strategies, given that the experimental group outperformed the control group on all four posttests, on the science CRCT and on the individual Science portions on the test including earth, life and physical sciences. In fact, this study was able to detect significant differences between the experimental group and the control group with regard to the degree to which the students improved from the pretests to the posttests.

This study aimed to evaluate the effectiveness of the delirium prevention interventions recommended by the Delirium Prevention Guidelines for Elderly Stroke Patients (DPGESP). The DPGESP comprises nine dimensions with 28 interventions, including risk factor assessment, orientation disorder prevention, sleeping pattern maintenance, sensory interventions, constipation, dehydration, hypoxia and infection prevention, pain management, and appropriate nutrition maintenance. This quasi-experimental study used a nonequivalent control group and a pretest-posttest design. The experimental and control groups each included 54 patients, and the participants were elderly patients who were admitted to the stroke unit. The study outcomes were the delirium incidence and severity, stroke impact, and length of hospitalization. Posttest values for delirium incidence, severity, stroke impact, and length of hospitalization were significantly improved in the experimental group. Implementation of the DPGESP had beneficial effects on the delirium incidence and severity, stroke impact, and length of hospitalization among elderly patients admitted to a stroke unit.

Long-term care institutions have become an option for older people who are dependent in daily living. However, insufficient attention has been focused on assessing the life satisfaction of those currently residing in these institutions in Taiwan. Previous research indicates that group reminiscence may improve the life satisfaction of older adults. However, there is currently no consensus regarding the implementation and evaluation of reminiscence interventions. To examine the effect of a structured group reminiscence protocol on the life satisfaction of institutionalized older adults. The study used a quasi-experimental design. A total of 48 older adults were conveniently recruited from two long-term care institutions in southern Taiwan. The experimental group (n = 23) received 8 weeks of structured-group reminiscence for 40 minutes weekly, while the control group (n = 25) received routine care from the institution. Both groups were evaluated using a life-satisfaction questionnaire before and after the intervention and again four weeks later. Life satisfaction scores were statistically similar on the pre-test and significantly different on both post-test questionnaires for the two groups. The scores for the experimental and control groups were pre-test: 24.22 vs 23.36 (p = .063); post-test I: 27.22 vs 23.32 (p < .001); and post-test II: 26.43 vs 23.00 (p < .001). The mean post-test scores for the experimental group were significantly higher than the pre-test score (p < .001). The generalized estimating equation test showed that the overall score of life satisfaction for the experimental group increased by 0.85-points (p = .042) more than the control group, which is a significant difference. The results support that the 8-week structured group reminiscence protocol effectively enhances life satisfaction in older adults. The results of this study may be referenced in the continuing education of nurses working in long-term care institutions in the context of helping nurses organize, facilitate, and evaluate this protocol.

Physical restraints are used to enhance the safety of patients and to avoid injury. However, physical restraints may cause injuries if improperly used or if they are used in the absence of continuous monitoring. Nursing staff who use physical restraints often lack sufficient related knowledge, which may increase the risk to patient safety. This study investigates the impact of an in-service education program for nursing staff that is designed to improve physical-restraint-related knowledge, attitudes, behaviors, and techniques. A pretest-posttest design and a quasi-experimental method were employed to evaluate the effectiveness of the in-service education program. One hundred thirty-six nursing staff from four adult intensive care units (ICUs), including two medical ICUs and two surgical ICUs, in a medical center in central Taiwan were enrolled as participants. The experimental group (EG) and the control group (CG) were composed of patients from one randomly assigned medical ICU and one randomly assigned surgical ICU each. The pretest data on physical-restraint-related knowledge, attitudes, behaviors, and techniques were collected before the in-service education program. The EG received 2 hours of classroom education on guidelines and techniques related to physical restraints. The posttest data for the two groups were collected a month after implementation of the in-service education program. General Estimation Equation was used to measure and analyze the data repeatedly. The posttest scores of the EG for knowledge and technique were significantly higher than the pretest scores (p < .0001). However, the posttest scores of the EG for attitudes and behaviors did not significantly differ from the pretest scores. In-service education for physical restraints enhances relevant knowledge and techniques but does not significantly affect attitudes or behaviors. Correct implementation of physical restraints not only promotes the quality of nursing care for patients in the ICU but also reduces the risk of physical-restraint-related complications. This study highlights the importance of changing the thoughts and concepts related to the use of physical restraints within the overall caring strategy of hospitals.

Burn patients experience high levels of pain and anxiety during dressing changes. Relaxation breathing is a simple behavioral intervention to manage pain and anxiety. However, the information about the effects of relaxation breathing on pain and anxiety levels for burn patients during dressing changes is limited. This study followed a quasi-experimental, pretest-posttest comparison group design without random assignment to groups. A total of 64 burn patients from Daejeon, South Korea were recruited by a convenience sequential sampling approach. With institutional approval and written consent, the experimental group practiced relaxation breathing during dressing change procedures. Data were collected from June to September 2011 using a VAS for pain and a VAS-A for anxiety. The homogeneity test was used to detect any significant group differences in the demographic data and pretest measures. The pain scores significantly differed between the 2 groups after intervention (RB group vs. control group, P=.01) and over time (pretest vs. posttest, P=.001). The anxiety scores significantly differed between the 2 groups (P=.01) and over time (P=.02). Relaxation breathing is a simple and inexpensive technique nurses can use to help burn patients manage pain and anxiety during dressing changes. Copyright © 2013 Elsevier Ltd and ISBI.

Faith-based programs have shown beneficial effects for health and behaviors. Few have specifically intervened on the spiritual, mental (i.e., stress), and physical dimensions of well-being combined for health and healthy behaviors (i.e., exercise and diet). The purpose of this report is to describe the feasibility of executing a spirituality-based health behavior change, program founded upon the Spiritual Framework of Coping. This study was a quasi-experimental one group pretest-posttest design. Feasibility objectives were assessed, and limited efficacy of pretest and posttest measures was analyzed using paired t test (p < .05). Acceptance of the program was positive, and modest demand was shown with initial interest and an average attendance of 78.7%. The program was successfully implemented as shown by meeting session objectives and 88% homework completion. The program was practical for the intended participants and was successfully integrated within the existing environment. Limited efficacy measures showed no pre-post changes. This study provided preliminary support for the design and further testing of the theoretical components of the Spiritual Framework of Coping that informed the program.

This study was conducted to examine the effect of a healthy nails program on nail-biting in Turkish schoolchildren. This quasi-experimental study was of pretest-posttest control group design. A total of 50 students of a primary school formed the intervention group, while 53 students from the same school formed the control group. Data were collected with a demographic form, a nail-biting follow-up form, and photographs of the fingernails. It was found that 68.9% of students were biting seven or more of their nails; 46.6% had damaged nail beds. In the intervention group, the rate of the children who were not biting their nails (baseline = 0%, 4th week = 56.0%, 8th week = 64.0%) increased significantly compared to the control group (baseline = 0%, 4th week = 15.1%, 8th week = 18.9%). Outcomes indicate the efficacy of the healthy nails program in reducing the nail-biting problem in schoolchildren.

To evaluate the effect of a culturally sensitive teaching unit on traditional midwives' knowledge of nursing interventions to prevent and treat postpartum hemorrhage (PPH). Sixteen midwives participated in a 1-day training program at a Refuge International Health Clinic in the remote town of Sarstun, Guatemala. The quasi experimental study used a one-group, pretest-posttest design. Researchers used a PPH Behavioral Checklist from the American College of Nurse Midwives (ACNM) to assess and compare knowledge of PPH interventions before and after the PPH teaching. The final analysis included 13 traditional midwives as the subjects. The culturally sensitive teaching improved traditional midwives' knowledge and skills about nursing interventions to manage PPH (pretest M = 1.385/8, posttest M = 4.846/8). Results of this pilot project suggest a culturally sensitive oral teaching in the primary language of the participants positively affects traditional midwives' knowledge and skills to manage PPH. Future training should be presented in a similar format to meet the needs of illiterate audiences in resource-poor settings.

While the knowledge mean scores of students regarding skin cancer and sun protection did not vary in the pre-test (6.2 ± 1.9) and post-test (6.8 ± 1.9) control group, the knowledge mean scores of students in the experimental group increased from 6.0 ± 2.3 to 10.6 ± 1.2 after the provided training. Some 25.4% of students in the experimental group had low knowledge level and 62.2% had medium knowledge level in the pre-test; whereas no students had low knowledge level and 94.3% had high knowledge level in the post-test. It was determined that tenth grade students, those who had previous knowledge on the subject, who considered themselves to be protecting from the sun better, had higher knowledge levels and their knowledge levels increased as the risk level increased. It was found that the provided training was effective and increased positively the knowledge, attitude and behaviour levels of students in the experimental group in terms of skin cancer and sun protection. Along with the provided training which started to form a lifestyle, appropriate attitudes and behaviours concerning skin cancer and sun protection could be brought to students who will work in outdoor spaces and are members of the maritime profession within the risk group.

Although statistical knowledge and skills are necessary for promoting evidence-based practice, health sciences students have expressed anxiety about statistics courses, which may hinder their learning of statistical concepts. To evaluate the effects of a biostatistics course on nursing students' attitudes toward statistics and to explore the association between these attitudes and their performance in the course examination. One-group quasi-experimental pre-test/post-test design. Undergraduate nursing students of the fifth or higher semester of studies, who attended a biostatistics course. Participants were asked to complete the pre-test and post-test forms of The Survey of Attitudes Toward Statistics (SATS)-36 scale at the beginning and end of the course respectively. Pre-test and post-test scale scores were compared, while correlations between post-test scores and participants' examination performance were estimated. Among 156 participants, post-test scores of the overall SATS-36 scale and of the Affect, Cognitive Competence, Interest and Effort components were significantly higher than pre-test ones, indicating that the course was followed by more positive attitudes toward statistics. Among 104 students who participated in the examination, higher post-test scores of the overall SATS-36 scale and of the Affect, Difficulty, Interest and Effort components were significantly but weakly correlated with higher examination performance. Students' attitudes toward statistics can be improved through appropriate biostatistics courses, while positive attitudes contribute to higher course achievements and possibly to improved statistical skills in later professional life.

Kurz, Jane McCausland

2014-06-01

Experts advocate educational programs addressing misinformation regarding donation decisions to increase the potential donor pool. However, few researchers have measured outcomes with nursing students. The purpose of this study was to evaluate the impact of an educational intervention on nursing students' knowledge, attitudes, registering as an organ donor, and family discussions. This quasi-experimental study used a pretest-posttest design with a control group. The research group consisted of 42 volunteers and the control group consisted of 73 volunteers. The written survey included 15 true-false knowledge items and 8 Likert items asking about attitude toward donation, registering as an organ donor, and family discussion. Normally distributed data showed no significant differences between groups on the pretest. The research group had no change in knowledge level 3 months later, but the control group had a significantly decreased knowledge level at that point. More members of the research group than the control group registered as organ donors after the intervention (χ2 = 4.5, P= .03). The control group had no change in registering as an organ donor between the pretest and posttest. Family discussions did not differ significantly from pretest to posttest in either group. One lecture/laboratory experience did make a difference in registering as an organ donor but not in discussing the decision with family members. Students can learn about organ donation from more than one specific class. Recommendations for educators and future research are provided.

To determine the effect of aromatherapy on pruritus observed in haemodialysis patients. Although the prevalence of pruritus in kidney failure has decreased in the recent years, pruritus is a difficult and serious problem which concerns the majority of haemodialysis patents and is hard to cure. A prospective, pretest-post-test quasi-experimental design was used. The research is quasi-experimental clinical trial conducted as pretest and post-test with control groups between January 2011-April 2012, in haemodialysis units of hospitals in Erzurum. The collection of the data is achieved using a questionnaire to detect the patients' individual and pruritus score scale and to clarify certain laboratory parameters regarding the pruritus. Chi-square analysis and t-test are used for the analysis of data. The experimental group's mean post-test pruritus scores (7·20 ± 3·14) were found to be lower than that of control group patients (10·00 ± 2·47), and a highly significant difference was found between the groups (p < 0·001). In the between-groups comparisons of experimental and control group's laboratory parameters, the experimental group's post-test blood urea nitrogen levels (118·26 ± 36·76) were found to be lower than that of control group patients (138·80 ± 48·69), and the between-groups difference was found to be statistically significant (p < 0·05). The results demonstrate that aromatherapy was found to decrease the pruritus problem of haemodialyses patients and led to positive changes in some laboratory parameters related to pruritus. One of the roles of health professionals is to advise individuals, who are living on this problem, using the nonpharmacological methods in checking the itching. By preventing or reducing uraemic pruritus, aromatherapy may also improve quality of life in this patient group. © 2014 John Wiley & Sons Ltd.

2009-01-01

The primary purpose of this study was to evaluate the effect of Web-based Braden Scale training on the reliability of Braden Scale subscale ratings made by nurses working in acute care hospitals. A secondary purpose was to describe the distribution of reliable Braden subscale ratings before and after Web-based Braden Scale training. Secondary analysis of data from a recently completed quasi-experimental, pretest-posttest, interrater reliability study. A convenience sample of RNs working at 3 Michigan medical centers voluntarily participated in the study. RN participants included nurses who used the Braden Scale regularly at their place of employment ("regular users") as well as nurses who did not use the Braden Scale at their place of employment ("new users"). Using a pretest-posttest, quasi-experimental design, pretest interrater reliability data were collected to identify the percentage of nurses making reliable Braden subscale assessments. Nurses then completed a Web-based Braden Scale training module after which posttest interrater reliability data were collected. The reliability of nurses' Braden subscale ratings was determined by examining the level of agreement/disagreement between ratings made by an RN and an "expert" rating the same patient. In total, 381 RN-to-expert dyads were available for analysis. During both the pretest and posttest periods, the percentage of reliable subscale ratings was highest for the activity subscale, lowest for the moisture subscale, and second lowest for the nutrition subscale. With Web-based Braden Scale training, the percentage of reliable Braden subscale ratings made by new users increased for all 6 subscales with statistically significant improvements in the percentage of reliable assessments made on 3 subscales: sensory-perception, moisture, and mobility. Training had virtually no effect on the percentage of reliable subscale ratings made by regular users of the Braden Scale. With Web-based Braden Scale training the percentage of nurses making reliable ratings increased for all 6 subscales, but this was true for new users only. Additional research is needed to identify educational approaches that effectively improve and sustain the reliability of subscale ratings among regular users of the Braden Scale. Moreover, special attention needs to be given to ensuring that all nurses working with the Braden Scale have a clear understanding of the intended meanings and correct approaches to rating moisture and nutrition subscales.

2018-04-01

An important goal of nursing education is helping students achieve core competencies efficiently. One proposed way of improving nursing education is team-based learning (TBL). The aim of this study was to assess the comparative effectiveness of TBL and lecture-style classes in terms of teaching core competencies in nursing education, which include clinical competence skills, problem-solving ability, communication competencies, critical thinking ability, and self-leadership. This quasi-experimental study enrolled 183 students as participants, with 95 and 88 in the experimental and control groups, respectively. These two groups attended 6 hours (2 hours weekly for 3 weeks) of TBL and lecture-style classes, respectively. Differences in core competencies between the two groups were compared before and after the intervention. The experimental group achieved significantly higher scores for clinical competence skills, communication competence, critical thinking ability, and self-leadership at posttest than at pretest, whereas the control group achieved significantly higher scores for clinical competence skills and critical thinking ability at posttest than at pretest. After the intervention, the experimental group had significantly better clinical competence skills, communication competence, and self-leadership than the control group. TBL is an effective approach method to teaching core competencies in nursing education.

Students (n = 394) from two similar public colleges in the Quebec City area (Canada) were asked to participate. A quasi-experimental design was used with a 14-week pause between the pretest and posttest. The control and experimental groups both received information on Canada's Food Guide recommendations. The experimental group was submitted to an intervention consisting of six interactive workshops carried out inside the college, and three personal exercises to be completed at home. proportion of respondents consuming at least five servings of fruits and vegetables daily. psychosocial variables assessed (theory of planned behaviour). The data collected from 344 participants by means of a self-administered questionnaire were analysed (167 experimental and 177 control). The posttest revealed a significant increase (15%) in the number of participants in the experimental group achieving the primary outcome (d = .38). The intervention also had a significant effect on the targeted psychosocial variables (η(2) = .03 to .06). Regularity of consumption acts as a mediator between intention and behaviour. These results may be used to guide health promoters working with college students.

Old age is a period when people need physical, emotional, and psychological support. Depression is the most prevalent mental health problem among older adults and it contributes to increase in medical morbidity and mortality, reduces quality of life and elevates health care costs. Therefore early diagnosis and effective management are required to improve the quality of life of older adults suffering from depression. Intervention like Mindfulness based Stress Reduction is a powerful relaxation technique to provide quick way to get rid of depression and negative emotions by increasing mindfulness. The study was undertaken to assess the effectiveness of MBSR on depression among elderly residing in residential homes, Bangalore. In this study, quasi experimental pre-test post-test control group research design was used. There were two groups: experimental and control, each group had 30 samples selected from different residential homes by non-probability convenience sampling technique. Pre-test depression and mindfulness was assessed before the first day of intervention. Experimental group participants were provided intervention on MBSR. Assessment of post-test depression and mindfulness was done at the end of the intervention programme for both group participants. The study revealed significant reduction in depression (p < 0.001) and increase in mindfulness (p < 0.001) among elderly in the experimental group who were subjected to MBSR technique.

Nurses must have optimum knowledge of heart failure self-care principles to adequately prepare patients for self-care at home. However, study findings demonstrate that nurses have knowledge deficits in self-care concepts for heart failure. A quasi-experimental, repeated measures design was used to assess nurses' knowledge of heart failure self-care before, immediately after, and 3-months following an educational intervention, which also included the Teach Back method. Follow-up reinforcement was provided after the educational intervention. One hundred fifty nurses participated in the study. Significant differences were found between pre-test (65.1%) and post-test (80.6%) scores (p < 0.001). Teach Back proficiency was achieved by 98.3%. Only 61 participants completed the 3-month assessment of knowledge. In this group, mean knowledge scores increased significantly across all three measurements (p < 0.001): 66.5% (pre-test); 82.1% (post-test); 89.5% (follow up post-test). Participation in a comprehensive educational program resulted in increased nurses' knowledge of heart failure self-care principles and the knowledge was sustained and increased over time.

Handling Totally Implantable Access Ports (TIAP) is a nursing procedure that requires skill and knowledge to avoid adverse events. No studies addressing this procedure with undergraduate students were identified prior to this study. Communication technologies, such as videos, have been increasingly adopted in the teaching of nursing and have contributed to the acquisition of competencies for clinical performance. To evaluate the effect of a video on the puncture and heparinization of TIAP in the development of cognitive and technical competencies of undergraduate nursing students. Quasi-experimental study with a pretest-posttest design. 24 individuals participated in the study. Anxiety scores were kept at levels 1 and 2 in the pretest and posttest. In relation to cognitive knowledge concerning the procedure, the proportion of correct answers in the pretest was 0.14 (SD=0.12) and 0.90 in the posttest (SD=0.05). After watching the video, the average score obtained by the participants in the mock session was 27.20. The use of an educational video with a simulation of puncture and heparinization of TIAP proved to be a strategy that increased both cognitive and technical knowledge. This strategy is viable in the teaching-learning process and is useful as a support tool for professors and for the development of undergraduate nursing students. Copyright © 2011 Elsevier Ltd.

This study investigated the impact of a collaborative clinical education model on students' perception of the psycho-social learning environment. A pre-test and post-test quasi experimental design. A tertiary referral centre. Second and third year undergraduate nursing students were asked to rate their perceptions of the psycho-social learning environment at the completion of the clinical practicum. TOOL: The tool used to measure psycho-social perceptions of the clinical learning environment was the Clinical Learning Environment Inventory previously validated in Australian health care contexts. A collaborative arrangement with the university and ward staff where eight students are placed on a ward and a ward staff member is paid by the university to be 'off-line' from a clinical workload to supervise the students. This is in contrast to the standard facilitation model where students are placed with registered nurses in different localities under the supervision of a 'roving' registered nurse paid by the university. No significant differences were found in pre-test mean scores when comparing wards. Significant differences in post-test scores for the intervention group were identified in the sub scales of Student Involvement, Satisfaction, Personalisation and Task Orientation. The adoption of a collaborative clinical education model where students are integrated into the ward team and the team is responsible for student learning can positively enhance capacity for student learning during their clinical practicum.

The flexibility of a hospital's nursing-related human resource management policies affects the working willingness and retention of nurses. To explore the effectiveness of a flexible nursing-related human resource management strategy. This quasi-experimental research used a one group pretest-posttest design. Supervisors at participating hospitals attended the "Application of Flexible Nursing Human Resources Management Strategies" workshop, which introduced the related measures and assessed nurses' pretest satisfaction. After these measures were implemented at the participating hospitals, implementation-related problems were investigated and appropriate consultation was provided. The posttest was implemented after the end of the project. Data were collected from nurses at the participating hospitals who had served in their present hospital for more than three months. The participating hospitals were all nationally certified healthcare providers, including 13 medical centers, 17 regional hospitals, and 3 district hospitals. A total of nurses 2,810 nurses took the pretest and 2,437 took the posttest. The research instruments included the "Satisfaction with working conditions and system flexibility" scale and the "Flexible nursing human resource management strategies". The effectiveness of the implemented strategy was assessed using independent samples t-test and variance analysis. The result of implementing the flexible strategies shows that the total mean of pretest satisfaction (Likert 5 scores) was 3.47 (SD = 0.65), and the posttest satisfaction was 3.52 (SD = 0.65), with significant statistical differences in task, numerical, divisional, and leading flexibility. Due to the good implementation effectiveness, the authors strongly suggest that all of the participating hospitals continue to apply this strategic model to move toward a more flexible nursing system and work.
Blended Learning Versus Traditional Lecture in Introductory Nursing Pathophysiology Courses.

Blissitt, Andrea Marie

2016-04-01

Currently, many undergraduate nursing courses use blended-learning course formats with success; however, little evidence exists that supports the use of blended formats in introductory pathophysiology courses. The purpose of this study was to compare the scores on pre- and posttests and course satisfaction between traditional and blended course formats in an introductory nursing pathophysiology course. This study used a quantitative, quasi-experimental, nonrandomized control group, pretest-posttest design. Analysis of covariance compared pre- and posttest scores, and a t test for independent samples compared students' reported course satisfaction of the traditional and blended course formats. Results indicated that the differences in posttest scores were not statistically significant between groups. Students in the traditional group reported statistically significantly higher satisfaction ratings than students in the blended group. The results of this study support the need for further research of using blended learning in introductory pathophysiology courses in undergraduate baccalaureate nursing programs. Further investigation into how satisfaction is affected by course formats is needed. Copyright 2016, SLACK Incorporated.

This study aims to examine the role of visual representation in physics learning and to compare the learning outcomes of using dynamic and static visualization media. The study was conducted using quasi-experiment with Pretest-Posttest Control Group Design. The samples of this research are students of six classes at State Senior High School in Lampung Province. The experimental class received a learning using dynamic visualization and control class using static visualization media. Both classes are given pre-test and post-test with the same instruments. Data were tested with N-gain analysis, normality test, homogeneity test and mean difference test. The results showed that there was a significant increase of mean (N-Gain) learning outcomes (p <0.05) in both experimental and control classes. The averages of students’ learning outcomes who are using dynamic visualization media are significantly higher than the class that obtains learning by using static visualization media. It can be seen from the characteristics of visual representation; each visualization provides different understanding support for the students. Dynamic visual media is more suitable for explaining material related to movement or describing a process, whereas static visual media is appropriately used for non-moving physical phenomena and requires long-term observation.

This study aimed to determine students' knowledge levels related to specific astronomy concepts and the effect of a planetarium environment on teaching. The study sample included seventh-grade (12-13 years old) students. For this purpose, 240 students of various socioeconomic and cultural levels from six schools (two in the city center, two in the districts and two in the villages) were enrolled in the study. The pretest-posttest control group quasi-experimental design was used in the study. The experimental and control groups were generated by random assignment. The "Solar System and Beyond" unit was selected. In the experimental group, the unit was taught with the use of a planetarium environment, whereas the same unit was taught to the control group students in a classroom environment. A test consisting of 14 multiple-choice questions was used as the pretest and posttest at the beginning and end of the unit. The data obtained were evaluated using the SPSS 20.0 software package program. The study results showed that teaching astronomical concepts in a planetarium environment was more effective than in a classroom environment. The study also revealed that students in the planetarium-assisted group were more successful in comprehending subjects that require 3D thinking, a reference system, changing the time and observation of periodic motion than those in control group.

2017-05-01

It is known that fathers whose infants are hospitalized in NICUs (Neonatal Intensive Care Units) are severely stressed. This study was conducted for the purpose of determining the effect of supporting and visiting infants in NICUs on stress levels of Turkish fathers. This was a pretest-posttest quasi-experimental study. The population of the study consisted of 47 fathers who had their infants receiving treatment in NICU at a state hospital in the eastern Turkey and agreed to participate in the study. The data were collected by using "Father-Infant Introductory Information Form" and "Parental Stressor Scale: Neonatal Intensive Care Unit, PSS:NICU". When comparing the PSS:NICU total mean scores of the fathers before and after interventions; it was determined that their mean scores were higher before visits compared to those obtained after interventions and the difference between them was significant at advanced level. It was found that the fathers visiting and supporting their infants in NICUs had the decreased stress levels. It is a useful nursing intervention to support fathers to visit their babies in NICUs and establish environments where they could spend time with their babies.

2016-08-01

This two-group quasi-experimental study investigated the effects of the Online Advance Organizer Concept Teaching Material (ONACOM) integrated with inquiry teaching and expository teaching methods. Grade 7 students' posttest performances on the light unit achievement and light unit attitude tests controlled for gender, previous semester science grade, and pretest scores were analyzed. No significant treatment effects were found between the inquiry and expository approaches. However, both groups demonstrated significant pretest-posttest gains in achievement and attitude. Independent from the method used, ONACOM was judged effective in both groups as students demonstrated increased achievement and attitude scores. ONACOM has a social and semantic network-aided infrastructure that can be adapted to both methods to increase students' achievement and improve their attitude.

Avşar, Fatma; Ayaz Alkaya, Sultan

The aim of this study was to determine the effectiveness of an assertive training for school-aged children on peer bullying and assertiveness. A quasi-experimental design using pre- and post-testing was conducted. Data were collected using a demographic questionnaire, an assertiveness scale, and the peer victimization scale. The training program was comprised of eight sessions which were implemented to intervention group. Descriptive characteristics were not statistically different between the groups (p>0.05). The peer victimization victim dimension results show that post-test mean scores of the students in the intervention group were lower than the pre-test mean scores (p<0.05). For the control group, no significant change was found in the pre-test and post-test mean scores (p>0.05). A comparison of the mean pre-test/post-test scores of peer-victimization bully dimension of the students' intervention and control groups revealed that the mean post-test scores of the students in the each group decreased (p>0.05). An assertiveness training program increased the assertiveness level and reduced the state of being victims, but did not affect the state of being bullies. The results of this study can help children acquire assertive behaviors instead of negative behaviors such as aggression and shyness, and help them to build effective social communication.

2015-04-01

To measure academic achievement of the multiple intelligence-based learning medium via a tablet device. This is a quasi-experimental research study (non-randomized control group pretest-posttest design) in 62 grade 1 elementary students (33 males and 29 females). Thirty-one students were included in an experimental group using purposive sampling by choosing a student who had highest multiple intelligence test scores in logical-mathematic. Then, this group learned by the new learning medium via a tablet which the application matched to logical-mathematic multiple intelligence. Another 31 students were included in a control group using simple random sampling and then learning by recitation. Both groups did pre-test and post-test vocabulary. Thirty students in the experimental group and 24 students in the control group increased post-test scores (odds ratio = 8.75). Both groups made significant increasing in post-test scores. The experimental group increased 9.07 marks (95% CI 8.20-9.93) significantly higher than the control group which increased 4.39 marks (95% CI 3.06-5.72) (t = -6.032, df = 51.481, p < 0.001). Although learning from either multiple intelligence-based learning medium via a tablet or recitation can contribute academic achievement, learningfrom the new medium contributed more achievement than recitation. The new learning medium group had higher post-test scores 8.75 times than the recitation group. Therefore, the new learning medium is more effective than the traditional recitation in terms of academic achievement. This study has limitations because samples came from the same school. However, the previous study in Thailand did notfind a logical-mathematical multiple intelligence difference among schools. In the future, long-term research to find how the new learning medium affects knowledge retention will support the advantage for life-long learning.

This study aims to evaluate the effect of light therapy on depression and sleep disruption in older adults residing in a long-term care facility. Psychological morbidity is a problem commonly seen in older adults residing in long-term care facilities. Limited research has addressed the effect of light therapy on depression in this population. A quasi-experimental pretest and posttest design was used. Thirty-four participants in the experimental group received light therapy by sitting in front of a 10000-lux light box 30 min in the morning, three times a week for 4 weeks. Thirty-one participants in the control group received routine care without light therapy. Depression was measured by Geriatric Depression Scale-Short Form at baseline and week 4. After receiving 4 weeks of light therapy, the mean depression score in the experimental group decreased from 7.24 (SD3.42) at pretest to 5.91 (SD 3.40) at posttest, and had a significant reduction (t = 2.22, P = 0.03). However, there was no significant difference in depression score and sleep disruption between the experimental group and control group. Light therapy might have the potential to reduce depressive symptoms and sleep disruption and may be a viable intervention to improve mental health of older adults in the long-term care facilities. © 2014 Wiley Publishing Asia Pty Ltd.

PubMed

Polat, Hatice; Ergüney, Seher

The purpose of this study was to determine the effect of reflexology on reducing dyspnea and fatigue in patients with chronic obstructive pulmonary disease (COPD). The study was conducted as a pretest-posttest experimental design. The population of the study consisted of 60 patients (30 in experimental group and 30 in control group). Patient Description Form, Baseline Dyspnea Index (BDI) and Visual Analogue Scale-Fatigue (VAS-F) were used to collect the data. The difference between pretest-posttest dyspnea and fatigue mean scores of patients in the experimental group was statistically significant (p < .01). The difference between pretest-posttest dyspnea and fatigue mean scores of patients in the control group was statistically insignificant (p > .05). It was determined that the reflexology reduced dyspnea and fatigue in patients with COPD. Complementary methods such as reflexology should be used with pharmacological methods to reduce dyspnea and fatigue of COPD patients.

Providing efficient basic life support (BLS) training is crucial for practicing nurses who provide direct patient care. Nevertheless, data addressing the impact of BLS courses on the skills and performance of Jordanian nurses are scarce. This study aimed to assess the effectiveness of a BLS simulation training on Jordanian nurses' skill improvement in cardiopulmonary resuscitation. A prospective quasi-experimental, single group pretest-posttest design was used to study the effect of BLS simulation; using a 9-item checklist; on the spot training; American Heart Association, on a group of Jordanian nurses. A pre-test was conducted following a CPR scenario to test the skills using 9-item checklist extrapolated from the American Heart Association guidelines. After debriefing, an interactive on spot training was provided. Later, participants undertook an unscheduled post-test after four weeks that included the same nine items. Thirty registered nurses with a mean clinical experience of 6.1years participated in the study. Comparing pre-test (M=4.6, SD=2.9, range=0 to 9) with post-test results (M=7.5, SD=1.7, range=4 to 9) showed an overall improvement in skills and BLS scores after the simulation training program (t=7.4, df=29, p<0.0001). BLS simulation training sessions are associated with significant improvement in skills and performance among Jordanian nurses. A refreshment BLS training session for nurses is highly recommended to guarantee nurses' preparedness in actual CPR scenarios. Copyright © 2015 Elsevier Ltd. All rights reserved.

The transtheoretical model was applied to promote behavioural change and test the effects of a group senior elastic band exercise programme on the functional fitness of community older adults in the contemplation and preparation stages of behavioural change. Forming regular exercise habits is challenging for older adults. The transtheoretical model emphasizes using different strategies in various stages to facilitate behavioural changes. Quasi-experimental design with pre-test and post-tests on two groups. Six senior activity centres were randomly assigned to either the experimental or control group. The data were collected during 2011. A total of 199 participants were recruited and 169 participants completed the study (experimental group n = 84, control group n = 85). The elastic band exercises were performed for 40 minutes, three times per week for 6 months. The functional fitness of the participants was evaluated at baseline and at the third and sixth month of the intervention. Statistical analyses included a two-way mixed design analysis of variance, one-way repeated measures analysis of variance and an analysis of covariance. All of the functional fitness indicators had significant changes at post-tests from pre-test in the experimental group. The experimental group had better performances than the control group in all of the functional fitness indicators after three months and 6 months of the senior elastic band exercises. The exercise programme provided older adults with appropriate strategies for maintaining functional fitness, which improved significantly after the participants exercising regularly for 6 months. © 2015 John Wiley & Sons Ltd.

This article reports on a study that evaluated the effectiveness of an educational intervention, Addressing Nurse Impairment, for addressing nursing students' knowledge acquisition, changes in self-efficacy to intervene, and changes in substance abuse stigma. A gap exists in nursing students' education regarding the risks of addiction within the profession and how to handle a colleague suspected of having a substance use disorder. The seminar was adapted from an existing evidence-based prevention program called Team Awareness, as well as information from focus groups and a pilot test. A quasi-experimental pretest-posttest design was used to evaluate the effect of the seminar. When the control and experimental groups were compared, the results indicated that the seminar significantly affected knowledge and self-efficacy to intervene but did not significantly affect stigma. This research contributes to the body of evidence related to educational interventions for nursing students regarding substance abuse in the nursing profession. Copyright 2012, SLACK Incorporated.

Museum-based learning: Informal learning settings and their role in student motivation and achievement in science

Holmes, Julie Ann

This study examined changes in student motivation and achievement in science in relationship with a visit to the IDEA Place Experiment Gallery. The study was based on the pretest-posttest control comparison group design with four treatment groups: control, exhibit, lesson, and exhibit/lesson. The sample was 228 sixth grade students from a public north central Louisiana school who were randomly assigned to one of the four experimental groups. Pretest, posttest, and delayed posttest measures of intrinsic motivation and achievement in science were determined using the Children's Academic Intrinsic Motivation Inventory and an achievement test written to measure areas of science incorporated in the Experiment Gallery exhibits. The data were analyzed using a one way Analysis of Variance (ANOVA), dependent t tests, and Pearson r. Statistical analysis revealed: (a) no significant differences in motivation or achievement on pretest and posttest scores between groups and, (b) no significant relationships between motivation level and achievement between groups on the posttest. Significant differences were found within groups for (a) the lesson group in motivation, and (b) the exhibit group in achievement from pretest to posttest and from posttest to delayed posttest. A significant relationship between level of motivation and science achievement was revealed for the exhibit group on the delayed posttests. There were no other significant findings to support that the effects of the treatment led to any long term effects on motivation or achievement within any of the four experimental groups.

The purpose of this research was to investigate the effectiveness of interactive self-paced computerized case study compared to traditional hand-written paper case study on the outcomes of student knowledge, attitude, and retention of the content delivered. Cognitive load theory (CLT) provided the theoretical framework for the study. A quasi-experimental pre-test post-test design with random group assignment was used to measure by self-report survey student cognitive load and interactivity level of the intervention. Student scores on quizzes in semester 1 and post-test follow-up quizzes in semester 3 were assessed for the intervention's effects on knowledge retention. While no significant statistical differences were found between groups, the students in the interactive case study group rated their case study as more fun and interactive. These students also scored consistently higher on the post-test quiz items in their third semester, showing the viability of using CLT to improve student retention of nursing curricula information.
Does Augmented Reality Affect High School Students' Learning Outcomes in Chemistry?

NASA Astrophysics Data System (ADS)

Renner, Jonathan Christopher

Some teens may prefer using a self-directed, constructivist, and technologic approach to learning rather than traditional classroom instruction. If it can be demonstrated, educators may adjust their teaching methodology. The guiding research question for this study focused on how augmented reality affects high school students' learning outcomes in chemistry, as measured by a pretest and posttest methodology when ensuring that the individual outcomes were not the result of group collaboration. This study employed a quantitative, quasi-experimental study design that used a comparison and experimental group. Inferential statistical analysis was employed. The study was conducted at a high school in southwest Colorado. Eighty-nine respondents returned completed and signed consent forms, and 78 participants completed the study. Results demonstrated that augmented reality instruction caused posttest scores to significantly increase, as compared to pretest scores, but it was not as effective as traditional classroom instruction. Scores did improve under both types of instruction; therefore, more research is needed in this area. The present study was the first quantitative experiment controlling for individual learning to validate augmented reality using mobile handheld digital devices that affected individual students' learning outcomes without group collaboration. This topic was important to the field of education as it may help educators understand how students learn and it may also change the way students are taught.

Type 2 diabetes is one of the most widespread diseases in the world. The main aim of this research was to evaluate the effect of combined therapy using acupressure therapy, hypnotherapy, and transcendental meditation (TM) on the blood sugar (BS) level in comparison with placebo in type 2 diabetic patients. We used "convenience sampling" for selection of patients with type 2 diabetes; 20 patients were recruited. For collection of data, we used an identical quasi-experimental design called "nonequivalent control group." Therapy sessions each lasting 60-90 min were carried out on 10 successive days. We prescribed 2 capsules (containing 3g of wheat flour each) for each member of the placebo group (one for evening and one for morning). Pre-tests, post-tests, and follow-up tests were conducted in a medical laboratory recognized by the Ministry of Health and Medical Education of Iran. Mean BS level in the post-tests and follow-up tests for the experimental group was reduced significantly in comparison with the pre-tests whereas in the placebo group no changes were observed. Combined therapy including acupressure therapy, hypnotherapy, and TM reduced BS of type 2 diabetic patients and was more effective than placebo therapy on this parameter. Copyright © 2011.

The first three years of a child's life are a critical period for brain growth and development. Caregiver interventions during this period that improve early childhood health and development have the potential to enhance a child's physical, mental, and social well-being. This was a pretest/posttest quasi experimental program evaluation. Early childhood education materials were adapted to create two separate interventions consisting of 30-page interactive flipchart talks to educate mothers on health and development topics relevant to 0-6 and 6-12 month old children. Three community health workers performed the talks with groups of 5-8 mothers. Short learning assessments were given individually to each mother pre-intervention (pretest), immediately post-intervention (posttest 1), and two weeks post-intervention (posttest 2). Demographic surveys and focus group discussions were conducted with all participants. Mothers ( n = 77) had an average age of 33.6 years and had an average of 3.6 living children. Most of the mothers (71%) had received some primary education, but 23% had received no formal schooling. For the 0-6 months flipchart learning assessment ( n = 38), the mean pretest score was 77% correct. The mean posttest 1 score improved to 87% ( p < 0.0001), and the mean posttest 2 score improved further from the mean posttest 1 score to 90% ( p = 0.01). For the 6-12 months flipchart learning assessment ( n = 39), the mean pretest score was 78%. The mean posttest 1 score improved to 89% ( p < 0.0001), and the mean posttest 2 score improved further from the mean posttest 1 score to 92% ( p = 0.03). Mothers in an impoverished region of southwestern Guatemala significantly increased their knowledge about child health topics following a short interactive group talk. Mothers further increased their knowledge two weeks after the intervention, without specific re-exposure to the intervention materials, suggesting assimilation and informal reinforcement through group based learning with other mothers in their community.

The effect of online collaborative learning on middle school student science literacy and sense of community

NASA Astrophysics Data System (ADS)

Wendt, Jillian Leigh

This study examines the effects of online collaborative learning on middle school students' science literacy and sense of community. A quantitative, quasi-experimental pretest/posttest control group design was used. Following IRB approval and district superintendent approval, students at a public middle school in central Virginia completed a pretest consisting of the Misconceptions-Oriented Standards-Based Assessment Resources for Teachers (MOSART) Physical Science assessment and the Classroom Community Scale. Students in the control group received in-class assignments that were completed collaboratively in a face-to-face manner. Students in the experimental group received in-class assignments that were completed online collaboratively through the Edmodo educational platform. Both groups were members of intact, traditional face-to-face classrooms. The students were then post tested. Results pertaining to the MOSART assessment were statistically analyzed through ANCOVA analysis while results pertaining to the Classroom Community Scale were analyzed through MANOVA analysis. Results are reported and suggestions for future research are provided.
The effects of analogy-based instruction on concept learning and retention in a non-formal coral reef ecology program

NASA Astrophysics Data System (ADS)

Brylske, Alexander Frederick

While a number of instructional models focus on the use of analogies, research into their effectiveness in enhancing comprehension and retention of scientific concepts, particularly involving adult learners, has been limited. The purpose of this study was to determine the efficacy of using the common teaching strategy for comparing the function of a coral reef to that of a city by using an analogy-based instructional model termed FAR. The training program entitled "Marine Resource Management for Dive Professionals" (MRMDP) was developed for this study. It was targeted to professionals in the recreational scuba industry to improve their understanding of coal reef ecology, as well as orient them to pertinent marine resource management issues, and promote environmentally-responsible attitudes and diving practices among their clients. A quasi-experimental pre-post-delayed posttest control group design was used to explore five research questions and corresponding hypotheses. A 55-item researcher-developed test of coral reef ecology was administered pre and post instruction. The delayed posttest was self-administered by the subjects three weeks after course completion. Data on seven experiential variables hypothesized as research factors were collected. Ten MRMPD courses were taught in seven nations, involving 194 subjects (85 subjects in four control courses, 109 in six treatment course). The results were analyzed using multiple regression/correlation (MRC) techniques to determine: (1) any significant relationship between pretest performance and experiential variables, (2) treatment versus control group posttest performance, and (3) treatment versus control group delayed posttest performance. Within the treatment group, learning gains and retention were determined by t-test analysis. Results indicated: (1) all research factors except one were significant predictors of pretest scores in the presence of the covariate; (2) no significant difference was found between control and treatment groups' pretest scores; (3) a significant interaction effect from a MANCOVA analysis, and resulting aptitude-treatment interaction analysis, showed group membership had a differential effect on the posttest relative to pretest scores; (4) the contribution of group membership to delayed posttest performance was significant; and (5) the treatment out-performed the control group on the posttest and delayed posttest. T-test analyses of treatment group performance showed a significant positive gain and retention.

2002-08-01

This study examined the 1-year effects of a minimal-contact smoking cessation intervention for cardiac inpatients. The multicenter study included cardiac inpatients who had smoked prior to hospitalization. A pretest-posttest quasi-experimental design was used. Patients' experimental condition depended on the hospital they were assigned to. The design was partially randomized: 4 of the 11 hospitals selected the experimental condition themselves (2 experimental, 2 control), while the remaining 7 hospitals were randomly assigned. The experimental group consisted of patients of 5 hospitals (N = 388). Patients of 6 other hospitals served as the control group (N = 401). The intervention included stop-smoking advice by the cardiologist, brief counseling by the nurse, the provision of self-help materials, and aftercare by the cardiologist. Logistic regression analyses controlling for baseline differences and covariates did not show significant intervention effects on point prevalence and continuous abstinence. The study also showed that the outcomes were not significantly related to the way hospitals were assigned to the experimental condition. While short-term effects were found, the minimal-contact intervention did not result in significant effects after 12 months, at least if patients lost to follow-up were treated as posttest smokers. Efforts should be made to improve the intervention, especially the aftercare.

2006-12-01

This study investigated the effects of aromatherapy massage on the anxiety and self-esteem experienced by Korean elderly women. A quasi-experimental, control group, pretest-posttest design was used. The subjects comprised 36 elderly females: 16 in the experimental group and 20 in the control group. Aromatherapy massage using lavender, chamomile, rosemary, and lemon was given to the experimental group only. Each massage session lasted 20 min, and was performed 3 times per week for two 3-week periods with an intervening 1-week break. The intervention produced significant differences in the anxiety and self-esteem and no significant differences in blood pressure or pulse rate between the two groups. These results suggest that aromatherapy massage exerts positive effects on anxiety and self-esteem. However, more objective, clinical measures should be applied in a future study with a randomized placebo-controlled design.
Reflections on experimental research in medical education.

PubMed

Cook, David A; Beckman, Thomas J

2010-08-01

As medical education research advances, it is important that education researchers employ rigorous methods for conducting and reporting their investigations. In this article we discuss several important yet oft neglected issues in designing experimental research in education. First, randomization controls for only a subset of possible confounders. Second, the posttest-only design is inherently stronger than the pretest-posttest design, provided the study is randomized and the sample is sufficiently large. Third, demonstrating the superiority of an educational intervention in comparison to no intervention does little to advance the art and science of education. Fourth, comparisons involving multifactorial interventions are hopelessly confounded, have limited application to new settings, and do little to advance our understanding of education. Fifth, single-group pretest-posttest studies are susceptible to numerous validity threats. Finally, educational interventions (including the comparison group) must be described in detail sufficient to allow replication.

Background Health education on proper inhaler usage is the most feasible and accessible strategy to increase inhaler effectiveness. Purpose To assess the impact of nurse-driven inhaler education on the compliance and proficiency of using inhalers among inhaler users. Methods This single-center, quasi-experimental study included the implementation of an individualized 60-min educational session on inhalers use. Health education and pretest and posttest outcomes were assessed by the Inhaler Proficiency Schedule and Patient Reported Behaviour tools. Results One hundred and twenty-one participants joined the study. At pretest, participants showed inadequate knowledge of general inhaler use. No previous training had been received by participants and difficulty with use and complications from using the inhalers were reported. At posttest, participants reported improvement in inhaler proficiency scores from 5.72 to 8.60 ( t = 17.99, df = 220, p < 0.001). Likewise, they showed a significant reduction towards the noncompliant behaviors from 15.21 to 11.19 ( t = 16.388, df = 238, p < 0.001). Conclusions Nurse-driven inhaler education yielded positive outcomes in both inhaler proficiency and compliance. The patients' assessment of using inhalers is crucial to determine the patients' educational deficits.

In Saskatoon in 2002, as one of the key strategies for the in motion health promotion strategy, the Forever...in motion program was developed with the general goal of increasing opportunities for physical activity among older adults living in congregate housing. The three components of the program were a low-intensity exercise program, informal socialization and educational sessions. The objective of the present study was to examine whether participation in this program positively influenced participants' physical, emotional, psychological and social well-being. A quasi-experimental, pretest/post-test design was employed to examine the impact of the program on various aspects of participant well-being. Thirty-six program participants and a comparison group of 22 non-participants from two congregate housing facilities took part in the study. The pretest was administered to the study and comparison groups before or shortly after the 12-week session commenced, and the post-test was administered after the 12-week session had concluded. Pretest and post-test assessment consisted of self-report measures of (1) vitality, (2) self-rated health, 3) mental health, (4) social functioning, (5) role limitations due to emotional problems, 6) physical activity-related knowledge, and (7) self-efficacy for exercise. A multivariate analysis of covariance (MANCOVA) was conducted using the seven post-test scores as dependent variables and the pretest scores as covariates. After adjusting for differences in baseline characteristics, the findings revealed statistically significant improvements in self-reported health and self-efficacy for exercise in the program participant group as compared with non-participants. The results of this study suggest that a relatively low-cost, low-intensity exercise program such as the Forever...in motion program may positively influence the well-being of older adults living in congregate housing. However, additional research with a larger number of participants and a more rigorous study design is needed to further elucidate the health benefits of the Forever...in motion program.

A quasi-experimental one group pretest/posttest design study was undertaken in two primary schools from two rural villages of Vhembe District in Limpopo Province, South Africa. About 172 children aged 9-14 years in Grades 5 and 6 were recruited for the study. All children in the grades were invited to participate pending written consent from parents and verbal assent from children. Due to school migration and absenteeism, only 154 children were available for posttest evaluation. However, nutrition education was administered to all 172 children. Nutrition education focused on types and health benefits of indigenous foods and was divided into three lessons. Observation and counting was used to note the responses given by children. The results suggest that the nutrition education was effective in imparting knowledge to children as well improving dietary diversification with indigenous foods. It is concluded that nutrition education is a valuable tool to change eating behaviors.
Effects of using the developing nurses' thinking model on nursing students' diagnostic accuracy.

This quasi-experimental study tested the effectiveness of an educational model, Developing Nurses' Thinking (DNT), on nursing students' clinical reasoning to achieve patient safety. Teaching nursing students to develop effective thinking habits that promote positive patient outcomes and patient safety is a challenging endeavor. Positive patient outcomes and safety are achieved when nurses accurately interpret data and subsequently implement appropriate plans of care. This study's pretest-posttest design determined whether use of the DNT model during 2 weeks of clinical postconferences improved nursing students' (N = 83) diagnostic accuracy. The DNT model helps students to integrate four constructs-patient safety, domain knowledge, critical thinking processes, and repeated practice-to guide their thinking when interpreting patient data and developing effective plans of care. The posttest scores of students from the intervention group showed statistically significant improvement in accuracy. Copyright 2012, SLACK Incorporated.

We tested the impacts of a professionally assisted peer group intervention on Chilean health workers' HIV-related knowledge, attitudes, and behaviors using a quasi-experimental design with a pretest and 3-month posttest. Two Santiago suburbs were randomly assigned to the intervention or delayed intervention control condition, and five community clinics per suburb participated. Interested workers at the intervention (n = 262) and control (n = 293) clinics participated and completed both evaluations. At posttest, intervention clinic workers had higher knowledge and more positive attitudes regarding HIV, condoms, stigmatization, and self-efficacy for prevention. They reported more partner discussion about safer sex, less unprotected sex, and more involvement in HIV prevention activities in the clinic and the community, but they did not report fewer sexual partners or more standard precautions behaviors. Because of these positive impacts, the program will become a regular continuing education unit that can be used to meet health worker licensing requirements. PMID:21497113

Statistical knowledge is widely used in academia; however, statistics teachers struggle with the issue of how to reduce students' statistics anxiety and enhance students' statistics learning. This study assesses the effectiveness of a "one-minute paper strategy" in reducing students' statistics-related anxiety and in improving students' statistics-related achievement. Participants were 77 undergraduates from two classes enrolled in applied statistics courses. An experiment was implemented according to a pretest/posttest comparison group design. The quasi-experimental design showed that the one-minute paper strategy significantly reduced students' statistics anxiety and improved students' statistics learning achievement. The strategy was a better instructional tool than the textbook exercise for reducing students' statistics anxiety and improving students' statistics achievement.

The Campbellian tradition provides a conceptual framework to assess threats to validity. On the other hand, different models of causal analysis have been developed to control estimation biases in different research designs. However, the link between design features, measurement issues, and concrete impact estimation analyses is weak. In order to provide an empirical solution to this problem, we use Structural Equation Modeling (SEM) as a first approximation to operationalize the analytical implications of threats to validity in quasi-experimental designs. Based on the analogies established between the Classical Test Theory (CTT) and causal analysis, we describe an empirical study based on SEM in which range restriction and statistical power have been simulated in two different models: (1) A multistate model in the control condition (pre-test); and (2) A single-trait-multistate model in the control condition (post-test), adding a new mediator latent exogenous (independent) variable that represents a threat to validity. Results show, empirically, how the differences between both the models could be partially or totally attributed to these threats. Therefore, SEM provides a useful tool to analyze the influence of potential threats to validity.

Although human patient simulators provide an innovative teaching method for nursing students, they are quite expensive. To investigate the value of this expenditure, a quantitative, quasi-experimental, two-group pretest and posttest design was used to compare two educational interventions: human patient simulators and interactive case studies. The sample (N = 49) consisted of students from baccalaureate, accelerated baccalaureate, and diploma nursing programs. Custom-designed Health Education Systems, Inc examinations were used to measure knowledge before and after the implementation of the two educational interventions. Students in the human patient simulation group scored significantly higher than did those in the interactive case study group on the posttest Health Education Systems, Inc examination, and no significant difference was found in student scores among the three types of nursing programs that participated in the study. Data obtained from a questionnaire administered to participants indicated that students responded favorably to the use of human patient simulators as a teaching method.
Power in randomized group comparisons: the value of adding a single intermediate time point to a traditional pretest-posttest design.

PubMed

Venter, Anre; Maxwell, Scott E; Bolig, Erika

2002-06-01

Adding a pretest as a covariate to a randomized posttest-only design increases statistical power, as does the addition of intermediate time points to a randomized pretest-posttest design. Although typically 5 waves of data are required in this instance to produce meaningful gains in power, a 3-wave intensive design allows the evaluation of the straight-line growth model and may reduce the effect of missing data. The authors identify the statistically most powerful method of data analysis in the 3-wave intensive design. If straight-line growth is assumed, the pretest-posttest slope must assume fairly extreme values for the intermediate time point to increase power beyond the standard analysis of covariance on the posttest with the pretest as covariate, ignoring the intermediate time point.

Health education programs supported by women's groups or workplaces have been successful in reaching large populations and changing intentions to perform breast health behaviors. This study examined the responses women working in the automotive industry had to two health education interventions, mailed pamphlets, and a combination of mailed material and classes at the worksite compared to a control group. A quasi-experimental design was used. Of the 948 women completing the pre-test, 437 also completed the post-test and were highly representative of the initial sample. The findings suggest that although the mailed information produced some change in practices and intentions, the classes in combination with the mailed pamphlets produced greater change. In addition, confidence in breast self examination as a method of detecting an existing breast lump increased from pre-test to post-test across all age groups. The reported influences on the women's decisions related to breast health varied across the life span. The results of this study can be used to support the development of effective health promotion programs for use at workplaces to increase the likelihood of women engaging in healthy breast practices.

To investigate whether Holotropic Breathwork™ (HB; Grof Transpersonal Training, Mill Valley, CA) has any significance in the development of self-awareness. A quasi-experiment design and multiple case studies. A single case design was replicated. The statistical design was a related within-subject and repeated-measures design (pre-during-post design). The study was conducted in Denmark. The participants (n = 20) were referred from Danish HB facilitators. Nine were novices and 11 had experience with HB. Four HB sessions. The novices (n = 9) underwent positive temperament changes and the experienced participants (n = 11) underwent positive changes in character. Overall, positive self-awareness changes were indicated; the participants' (n = 20) scores for persistence temperament, interpersonal problems, overly accommodating, intrusive/needy, and hostility were reduced. Changes in temperament were followed by changes in paranoid ideation scale, indicating a wary phase. Participants (n = 20) experienced reductions in their persistence temperament scores. The pretest mean (mean ± standard deviation, 114.15 ± 16.884) decreased at post-test (110.40 ± 16.481; pre-during-test p = 0.046, pre-post-test p = 0.048, pre-post-test effect size [d] = 0.2). Temperament changes were followed by an increase in paranoid ideation; the pre-test mean (47.45 ± 8.88) at post-test had increased to a higher but normal score (51.55 ± 7.864; pre-during-test p = 0.0215, pre-post-test p = 0.021, pre-post-test d = 0.5). Pre-test hostility mean (50.50 ± 10.395) decreased at post-test (47.20 ± 9.001; p = 0.0185; d = 0.3). The Inventory of Interpersonal Problems total pre-test mean (59.05 ± 17.139) was decreased at post-test (54.8 ± 12.408; p = 0.044; d = 0.2). Overly accommodating pre-test mean (56.00 ± 12.303) was decreased at post-test (51.55 ± 7.797; p = 0.0085; d = 0.4). The intrusive/needy pre-test score (57.25 ± 13.329) was decreased at post-test (52.85 ± 10.429; p = 0.005; d = 0.4). The theoretical conclusion is that HB can induce very beneficial temperament changes, which can have positive effects on development of character, measured as an increase in self-awareness.

The purpose of the study was to measure knowledge and attitudes of nursing about pain management in patients before education, immediately after, and 6 months later. The end-point measure was Hospital Consumer Assessment of Healthcare Providers and Systems quarterly scores and percentile rank. This longitudinal, quasi-experimental, quantitative study used survey method with pretest and posttest scores to measure immediate learning and 6 months later to measure sustained changes in knowledge and attitudes for nurses in this facility. The setting was a 360-bed acute care community hospital in the midsouth. The sample consisted of approximately 206 bedside nurses who worked in an acute care facility and 164 final posttest participants. The survey was used in a group setting immediately prior to a didactic learning experience. Immediately after the session, a posttest survey was administered. The 6-month follow-up occurred via an online module developed by the principal investigator. A repeated-measures analysis of variance, a pairwise comparison with a paired t test, and a Bonferroni correction were performed to determine if sustained knowledge and attitudes have changed. Posttest scores were significantly higher than pretest scores on the Knowledge and Attitudes Survey Regarding Pain immediately after a didactic education session and 6 months later (P < .017). Six months later, scores remained higher than pretest or immediate posttest scores. Nurses with a stronger knowledge base may lead to better pain management, improved outcomes, and higher patient satisfaction scores.

The primary purpose of this quasi-experimental research is to observe health care workers' compliance with hand-hygiene guidelines during patient care in an intensive care unit in Ireland before (pretest) and after (posttest) implementation of a multifaceted hand-hygiene program. Health care workers' attitudes, beliefs, and knowledge in relation to compliance with handwashing guidelines were also investigated. A convenience sample of nurses, doctors, physiotherapists, and care assistants (n = 73 observational participants, n = 62 questionnaire respondents) was used. Data (N = 314 observations, 62 questionnaires) were analyzed descriptively and cross-tabulated using chi-square (Pearson's) and Mann-Whitney statistical tests. Results revealed that a significant shift (32%) occurred in health care workers' compliance with handwashing guidelines (pretest 51%, posttest 83%, p < .001) following the interventional hand-hygiene program. Significant changes were also found in relation to health care workers' attitudes, beliefs, and knowledge (p < .05).

Using a pretest and posttest comparison group design, this 20 weeks study investigated the effects of a phonological awareness training program (PATP) on attention efficiency (AE) in 57 children (age = 5 to 6 years) at risk. The experimental group received the PATP (EG; n=30). We obtained pretest and posttest measures of phonological awareness and AE. The ANOVA showed significant interaction effects of the PATP and time on phonological awareness and AE. For both groups, posttest AE score means were higher than pretest score means. Pretest measures showed that the AE score mean for the EG was lower than that for the Control Group (CG; n=31); whereas posttest data showed no between group differences. Contrast analysis showed that the EG gained a greater level of phonological awareness ability and AE over CG. Our results indicate that children's attention efficiency not only improved as they developed, but also increased by means of a PATP.

This study compared two treatments on learning activity in middle school. The metacognitive strategies have applied to the content of environmental pollution at 7th grade. This study used a quantitative approach with quasi-experimental method. The research sample were the 7th grade students, involves 27 students in the experimental through Inquiry Lab and 27 students in the experimental through Group Investigation. The instruments that used in this research were pretest and posttest quantitative literacy skills, learning step observation sheets, and the questionnaire of teachers and students responses. As the result, N-gain average of pretest and posttest increased in both experimental groups. The average of posttest score was 61,11 for the Inquiry Lab and 54,01 to the Group Investigation. The average score of N-gain quantitative literacy skill of Inquiry Lab class was 0,492 and Group Investigation class was 0,426. Both classes of experiments showed an average N-gain in the medium category. The data has been analyzed statistically by using SPSS ver.23 and the results showed that although both the learning model can develop quantitative literacy, but there is not significantly different of improving students’ quantitative literacy between Inquiry Lab and Group Investigation in environmental pollution material.
Increasing girls’ knowledge about human papillomavirus vaccination with a pre-test and a national leaflet: a quasi-experimental study

2013-01-01

Background Adolescent girls are at an age to be involved in the decision about HPV vaccination uptake and therefore need adequate information about the vaccination. This study assesses to what extent reading an official information leaflet about HPV contributes to girls’ knowledge levels, and to what extent an increase in knowledge is boosted by a pre-test measurement. Methods Participants (girls aged 11–14 years) were systematically allocated to group A that completed a pre-test measurement (12 true/false statements) or to group B that did not complete it. Subsequently, both groups read the HPV leaflet and completed the post-test measurement. Results The response rate was 237/287 (83%). Pre-test scores in group A (M = 3.6, SD = 1.81, p < 0.001) were lower than post-test mean knowledge scores (0–10) in group B (M = 4.6, SD = 2.05). Post-test knowledge scores in group A were higher than those in group B [6.2 (SD = 2.06) versus 4.6 (SD = 2.05), p < 0.001]. In the post-test measurement, about a third of both groups knew that vaccinations do not give 100% protection against cervical cancer and that the duration of protection is unknown. Conclusions Reading the information leaflet had a positive effect on knowledge, even more so when boosted by a pre-test measurement. However, knowledge on the degree and duration of protection against cervical cancer remained limited. Focusing girls’ attention on important aspects before they start reading the leaflet (e.g. by including a quiz on the first page) may serve to raise their awareness of these aspects. PMID:23802703

The purpose of this study was to explore the effectiveness of the creative inquiry-based science teaching on students' creative science thinking and science inquiry performance. A quasi-experimental design consisting one experimental group (N = 20) and one comparison group (N = 24) with pretest and post-test was conducted. The framework of the intervention focused on potential strategies such as promoting divergent and convergent thinking and providing an open, inquiry-based learning environment that are recommended by the literature. Results revealed that the experimental group students outperformed their counterparts in the comparison group on the performances of science inquiry and convergent thinking. Additional qualitative data analyses from classroom observations and case teacher interviews identified supportive teaching strategies (e.g. facilitating associative thinking, sharing impressive ideas, encouraging evidence-based conclusions, and reviewing and commenting on group presentations) for developing students' creative science thinking.

The purpose of this study was to identify the effects of a footbath on post-partum fatigue. This study used a quasi-experimental design by using an unequivalent control group, pre-post-test design. The participants were divided into experimental and control groups. Fifty post-partum women who were admitted to an obstetrics and gynecology ward of a general hospital were the experimental group and 50 post-partum women who were admitted to an obstetrics and gynecology ward of a women's hospital were the control group. Two hospitals were providing similar postnatal care to their patients and they were located in the same city. The experimental group received a footbath along with postnatal care at the hospital, while the control group received only postnatal care from the hospital. Each group completed the Fatigue Continuum Form at a specified time. The general characteristics and pretest dependent variables were homogenous between the two groups. The hypothesis was supported post-test as the Fatigue Continuum Form scores differed significantly between the experimental and the control groups. This study showed that a footbath helps to decrease fatigue among post-partum women. In addition, it is a good preventative strategy for post-partum women who should initiate it in the early post-partum period. © 2016 Japan Academy of Nursing Science.

A first aim of this study is to evaluate the efficacy of an open group therapy for sexually abused teenagers using a quasi-experimental pretest/posttest treatment design. A second aim was to explore whether differential gains were linked to an open versus a closed group format. Results indicate that sexually abused girls involved in an open group therapy showed significant gains relative to teenagers of the control group girls for the majority of the variables considered. Analyses contrasting the two formats of group therapy fail to identify statistical differences suggesting that both open and closed group formats are likely to be associated with the same significant gains for sexually abused teenagers.

Individuals with Alzheimer disease (IwAD) experience more frequent and more injurious falls than their cognitively intact peers. Evidence of balance and gait dysfunction is observed earlier in the course of Alzheimer disease (AD) than once believed. Balance training has been demonstrated to be effective in improving balance and decreasing falls in cognitively intact older adults but is not well studied in IwAD. This study was designed to analyze the effects of a group balance training program on balance and falls in IwAD. The program was developed specifically for IwAD, with explicit guidelines for communication/interaction and deliberate structure of training sessions catered to the motor learning needs of IwAD. This prospective, quasi-experimental, pretest-posttest design study describes the effects of a balance training program for a cohort of IwAD. Thirty IwAD were recruited from 3 adult day health centers; 22 completed at least 1 posttest session. Participants were tested with Berg Balance Scale (BBS), Timed Up and Go (TUG), Self-Selected Gait Speed (SSGS), Fast Gait Speed (FGS), and Mini-Mental Status Examination (MMSE) immediately before and after the 3-month intervention and again 3 months later. Group training was held at the adult day health centers for 45 minutes, twice per week. Sessions were characterized by massed, constant, and blocked practice of functional, relevant activities with considerable repetition. Ratio of participant to staff member never exceeded 3:1. Physical therapist staff members assured that participants were up on their feet the majority of each session and were individually challenged as much as possible. Repeated-measures analysis of variance (ANOVA) for BBS was significant (F = 15.04; df = 1.67/28.40; P = .000) with post hoc tests, revealing improvement between pretest and immediate posttest (P = .000) and decline in performance between immediate and 3-month posttest (P = .012). Repeated-measures ANOVA posttest for MMSE was significant (F = 5.12; df = 1.73/22.53; P = .018) with post hoc tests, showing no change in MMSE between pretest and immediate posttest but decline in MMSE when comparing immediate posttest with 3-month posttest (P = .038) and pretest with 3-month posttest (P = .019). Repeated-measures ANOVA for TUG, FGS, and SSGS were not significant. Immediate effects of the intervention as assessed by the a priori paired t tests (comparing pre- and immediate posttest data) revealed significant improvement in BBS (t = -7.010; df = 20; P = .000), TUG (t = 3.103; df = 20; P = .006), and FGS (t = -2.115; df = 19; P = .048), but not in SSGS (t = -1.456; df = 20; P = .161). The 3-month group balance training intervention designed specifically for IwAD was effective in improving balance and mobility, as evidenced by improved BBS and TUG performances. Cognition did not decline during the course of the intervention but did decline following the intervention, suggesting a possible protective effect. Given the promising findings, a larger-scale controlled study is warranted.

Skin care is an important responsibility of nurse aides in long-term care facilities, and the nursing knowledge, attitudes, and skills of these aides significantly affects quality of care. However, the work schedule of nurse aides often limits their ability to obtain further education and training. Therefore, developing appropriate and effective training programs for nurse aides is critical to maintaining and improving quality of care in long-term care facilities. This study investigates the effects of multimedia assisted instruction on the skin care learning of nurse aides working in long-term care facilities. A quasi-experimental design and convenient sampling were adopted in this study. Participants included 96 nurse aides recruited from 5 long-term care facilities in Taoyuan County, Taiwan. The experimental group received 3 weeks of multimedia assisted instruction. The control group did not receive this instruction. The Skin Care Questionnaire for Nurse Aides in Long-term Care Facilities and the Skin Care Behavior Checklist were used for assessment before and after the intervention. (1) Posttest scores for skin care knowledge, attitudes, behavior, and the skin care checklist were significantly higher than pretest scores for the intervention group. There was no significant difference between pretest and posttest scores for the control group. (2) A covariance analysis of pretest scores for the two groups showed that the experimental group earned significantly higher average scores than their control group peers for skin care knowledge, attitudes, behavior, and the skin care checklist. The multimedia assisted instruction demonstrated significant and positive effects on the skin care leaning of nurse aides in long-term care facilities. This finding supports the use of multimedia assisted instruction in the education and training of nurse aides in long-term care facilities in the future.

The aging of society is a global trend, and care of older adults with dementia is an urgent challenge. As dementia progresses, patients exhibit negative emotions, memory disorders, sleep disorders, and agitated behavior. Agitated behavior is one of the most difficult problems for family caregivers and healthcare providers to handle when caring for older adults with dementia. The aim of this study was to investigate the effectiveness of white noise in improving agitated behavior, mental status, and activities of daily living in older adults with dementia. An experimental research design was used to study elderly participants two times (pretest and posttest). Six dementia care centers in central and southern Taiwan were targeted to recruit participants. There were 63 participants: 28 were in the experimental group, and 35 were in the comparison group. Experimental group participants received 20 minutes of white noise consisting of ocean, rain, wind, and running water sounds between 4 and 5 P.M. daily over a period of 4 weeks. The comparison group received routine care. Questionnaires were completed, and observations of agitated behaviors were collected before and after the intervention. Agitated behavior in the experimental group improved significantly between pretest and posttest. Furthermore, posttest scores on the Mini-Mental Status Examination and Barthel Index were slightly better for this group than at pretest. However, the experimental group registered no significant difference in mental status or activities of daily living at posttest. For the comparison group, agitated behavior was unchanged between pretest and posttest. The results of this study support white noise as a simple, convenient, and noninvasive intervention that improves agitated behavior in older adults with dementia. These results may provide a reference for related healthcare providers, educators, and administrators who care for older adults with dementia.

2015-06-01

This research was aimed to construct and develop a unique system for training of pedestrians - children, adults and older persons - to cross streets safely and especially to detect successfully on-road hazards as pedestrians. For this purpose, an interactive computerized program has been inspired by the format of the popular HPT (hazard perception test) for drivers. The HPTP (hazard perception test for pedestrians) includes 10 pairs of video clips that were filmed in various locations but had a similar hazardous element. The clips presented potentially dangerous crossing scenarios such as a vehicle merging from the right side of the road from the perspective of the pedestrian who is trying to cross the street. The participants were asked to press the spacebar key every time they identified an approaching hazard. The participants were instructed to use the arrow keys for moving the viewing panel to the left or to the right in order to enlarge the field of view accordingly. Totally, 359 participants took part. Adults, children, and elders were assigned to two practice groups and three control groups in a 3 (age groups)×5 (experimental groups) design. One practice group underwent pretest, practice, discussion and posttest, the second experimental group through pretest, practice and posttest, one control group that underwent posttest only, the second control group underwent pretest, discussion and posttest and the third control group underwent both pretest and posttest. The most important finding was that children and adults who underwent practice received higher scores in the posttest compared to the pretest. Also, children who underwent practice increased their use of the arrow keys in the posttest compared to the pretest. Across conditions men scored higher than women on the HPTP, and used the keys more often. Age differences were found, with adults scoring being the highest, followed by children and the older persons. Copyright © 2015 Elsevier Ltd. All rights reserved.

Mathew, Easow

The purpose of this research was to determine if there were differences in academic performance between students who participated in traditional versus collaborative problem-based learning (PBL) instructional design approaches to physics curricula. This study utilized a quantitative quasi-experimental design methodology to determine the significance of differences in pre- and posttest introductory physics exam performance between students who participated in traditional (i.e., control group) versus collaborative problem solving (PBL) instructional design (i.e., experimental group) approaches to physics curricula over a college semester in 2008. There were 42 student participants (N = 42) enrolled in an introductory physics course at the research site in the Spring 2008 semester who agreed to participate in this study after reading and signing informed consent documents. A total of 22 participants were assigned to the experimental group (n = 22) who participated in a PBL based teaching methodology along with traditional lecture methods. The other 20 students were assigned to the control group (n = 20) who participated in the traditional lecture teaching methodology. Both the courses were taught by experienced professors who have qualifications at the doctoral level. The results indicated statistically significant differences (p < .01) in academic performance between students who participated in traditional (i.e., lower physics posttest scores and lower differences between pre- and posttest scores) versus collaborative (i.e., higher physics posttest scores, and higher differences between pre- and posttest scores) instructional design approaches to physics curricula. Despite some slight differences in control group and experimental group demographic characteristics (gender, ethnicity, and age) there were statistically significant (p = .04) differences between female average academic improvement which was much higher than male average academic improvement (˜63%) in the control group which may indicate that traditional teaching methods are more effective in females, whereas there was no significant difference noted in the experimental group between male and female participants. There was a statistically significant and negative relationship (r = -.61, p = .01) between age and physics pretest scores in the control group. No statistical analyses yielded significantly different average academic performance values in either group as delineated by ethnicity.

Milanti, Ariesta; Metsälä, Eija; Hannula, Leena

Psychological distress is a common problem among patients with cancer, yet it mostly goes unreported and untreated. This study examined the association of a psycho-educational intervention with the psychological distress levels of breast cancer and cervical cancer patients undergoing chemotherapy. The design of the study was quasi-experimental, pretest-posttest design with a comparison group. One hundred patients at a cancer hospital in Jakarta, Indonesia, completed Distress Thermometer screening before and after chemotherapy. Fifty patients in the intervention group were given a psycho-educational video with positive reappraisal, education and relaxation contents, while receiving chemotherapy. Patients who received the psycho-educational intervention had significantly lower distress levels compared with those in the control group. Routine distress screening, followed by distress management and outcome assessment, is needed to improve the wellbeing of cancer patients.
Dedicated Education Units: Partnerships for Building Leadership Competency.

Galuska, Lee A

2015-07-01

To enable nurses to lead in health care transformation, nursing education must include opportunities for developing leadership, as well as clinical competencies. Dedicated education units (DEUs) provide supportive environments for competency development in undergraduate students. This study's aim was to explore the effects of a DEU experience on the leadership development of baccalaureate nursing students. A mixed-methods design included a quantitative strand, using a quasi-experimental, pretest-posttest, multisite design with control groups and a qualitative strand using focus groups. Students in the DEUs demonstrated significant increases (p < 0.01) in leadership behaviors, as measured by the Student Leadership Practice Inventory. Focus group themes illuminate how the experiences of the students contributed to their leadership growth. Findings suggest that the DEU experience may promote enhanced undergraduate leadership competency development. Copyright 2015, SLACK Incorporated.

2015-01-01

Abstract Objectives: To investigate whether Holotropic Breathwork™ (HB; Grof Transpersonal Training, Mill Valley, CA) has any significance in the development of self-awareness. Design: A quasi-experiment design and multiple case studies. A single case design was replicated. The statistical design was a related within-subject and repeated-measures design (pre-during-post design). Setting/location: The study was conducted in Denmark. Participants: The participants (n = 20) were referred from Danish HB facilitators. Nine were novices and 11 had experience with HB. Intervention: Four HB sessions. Outcome measures: The novices (n = 9) underwent positive temperament changes and the experienced participants (n = 11) underwent positive changes in character. Overall, positive self-awareness changes were indicated; the participants' (n = 20) scores for persistence temperament, interpersonal problems, overly accommodating, intrusive/needy, and hostility were reduced. Changes in temperament were followed by changes in paranoid ideation scale, indicating a wary phase. Results: Participants (n = 20) experienced reductions in their persistence temperament scores. The pretest mean (mean ± standard deviation, 114.15 ± 16.884) decreased at post-test (110.40 ± 16.481; pre–during-test p = 0.046, pre–post-test p = 0.048, pre–post-test effect size [d] = 0.2). Temperament changes were followed by an increase in paranoid ideation; the pre-test mean (47.45 ± 8.88) at post-test had increased to a higher but normal score (51.55 ± 7.864; pre–during-test p = 0.0215, pre–post-test p = 0.021, pre–post-test d = 0.5). Pre-test hostility mean (50.50 ± 10.395) decreased at post-test (47.20 ± 9.001; p = 0.0185; d = 0.3). The Inventory of Interpersonal Problems total pre-test mean (59.05 ± 17.139) was decreased at post-test (54.8 ± 12.408; p = 0.044; d = 0.2). Overly accommodating pre-test mean (56.00 ± 12.303) was decreased at post-test (51.55 ± 7.797; p = 0.0085; d = 0.4). The intrusive/needy pre-test score (57.25 ± 13.329) was decreased at post-test (52.85 ± 10.429; p = 0.005; d = 0.4). Conclusions: The theoretical conclusion is that HB can induce very beneficial temperament changes, which can have positive effects on development of character, measured as an increase in self-awareness.

Effective communication is important for nurse and patient outcomes. Nursing students often feel unprepared to communicate effectively with patients and other healthcare workers within the clinical environment. Blended learning pedagogy-based communication skills training can provide an alternative to traditional methods of teaching to enhance students' satisfaction and self-efficacy levels in communicating with others. To examine the effectiveness of blended learning pedagogy in a redesigned communication module among nursing undergraduates in enhancing their satisfaction levels and attitudes towards learning communication module as well as self-efficacy in communication. A single group pre-test and post-test quasi-experimental design was adopted. Data were collected from August 2016 to November 2016 from 124 nursing undergraduates from a leading nursing school. Blended learning pedagogy was adopted to redesign a communication module that offered a wide array of learning opportunities via face-to-face classroom and online sessions. Validated and reliable instruments were used to measure satisfaction levels with blended learning pedagogy, attitudes towards learning communication, and communication self-efficacy. Descriptive and inferential statistics were used to analyze the data. Participants had enhanced satisfaction levels with blended learning pedagogy, better attitudes in learning communication skills, and improved communication self-efficacies at posttest (week 13 of the semester) when compared with their pre-test scores (week one of the semester). Participants scored higher in the Blended Learning Satisfaction Scale, the Communication Skills Attitude Scale, and the communication skills subscale of the Nursing Students Self-Efficacy Scale. Blended learning pedagogy can be effectively used in facilitating communication modules and enhancing student outcomes among nursing undergraduates. The long-term effectiveness of using blended learning pedagogy in facilitating communication modules should be evaluated from students' and patients' perspectives. Additionally, the technology should be constantly improved by incorporating more interactive functions and should be tested to accommodate the learners' needs. Copyright © 2017 Elsevier Ltd.

Caregiving across different cultures has been perceived conventionally as a private or family responsibility, predominantly performed by women who accept their caregiving as part of their gender role. This study aimed to design, deliver, and evaluate an elderly training programme for women by assessing their knowledge, attitudes and skills as a lay caregiver. Encouraging the women to find suitable positions for employment in private or governmental institutions was the further objective of the study. The study was a quasi-experimental one-group pre-test post-test design. The study was conducted in a solidarity centre for women and in a nursing home for the elderly. The sample covered 120 women selected from the community by convenience sampling. Data were gathered through pre- and post-test evaluation and observation forms in 2 May-22 December 2005. The training programme consisted of 230 h of didactic sessions, demonstrations and clinical practices. The mean change in the participants' knowledge score (pre-test: 41.44 +/- 0.92; post-test: 71.16 +/- 1.34) demonstrated a statistically significant improvement in their knowledge. According to clinical observations, most of them displayed satisfactory caring and communication skills towards the elderly. Virtually all participants reported increased skill, knowledge and confidence. The developed training programme was effective, resulting in an increased knowledge, the acquisition of good attitudes towards the elderly, and performing satisfactory caring and communication skills. Similar community-based programmes managed by nurses are recommended to support non-professional caregivers. The research is not only an innovative but also a revolutionary model to promote women.
Promoting Experimental Problem-solving Ability in Sixth-grade Students Through Problem-oriented Teaching of Ecology: Findings of an intervention study in a complex domain

Roesch, Frank; Nerb, Josef; Riess, Werner

2015-03-01

Our study investigated whether problem-oriented designed ecology lessons with phases of direct instruction and of open experimentation foster the development of cross-domain and domain-specific components of experimental problem-solving ability better than conventional lessons in science. We used a paper-and-pencil test to assess students' abilities in a quasi-experimental intervention study utilizing a pretest/posttest control-group design (N = 340; average performing sixth-grade students). The treatment group received lessons on forest ecosystems consistent with the principle of education for sustainable development. This learning environment was expected to help students enhance their ecological knowledge and their theoretical and methodological experimental competencies. Two control groups received either the teachers' usual lessons on forest ecosystems or non-specific lessons on other science topics. We found that the treatment promoted specific components of experimental problem-solving ability (generating epistemic questions, planning two-factorial experiments, and identifying correct experimental controls). However, the observed effects were small, and awareness for aspects of higher ecological experimental validity was not promoted by the treatment.
The effect of pedagogy informed by constructivism: A comparison of student achievement across constructivist and traditional classroom environments

NASA Astrophysics Data System (ADS)

Gatlin, Linda Sue

Implicit in the call for educational reform in the teaching of science has been the suggestion that pursuing constructivist principles in science teaching will lead to improvement in student achievement. (Rutherford & Ahlgren, 1990; National Research Council, 1995; NSTA, 1992). The purpose of this study was to compare the effectiveness of two types of pedagogy; didactic/traditional and constructivist-informed pedagogy on student achievement. Secondly, this study examined the relationship between students' and teachers' perception of constructivism in classroom environments. A nonequivalent control group pretest-posttest and delayed posttest quasi-experimental design was used in this study. Subjects involved in this study included two teachers and their respective students from a suburban public school district in the South. The sample consisted of two groups, one taught by traditional/didactic instruction (n = 25) and the other taught by constructivist informed pedagogy (n = 26). Data for this study was collected using the Constructivist Learning Environmental Survey, The Science Classroom Observation Rubric, the Teaching Practices Assessment, and a demographic survey. Ancillary data was collected with the Student Outcome Assessment and interpretive methodologies. The analysis of covariance (ANCOVA) (p < .05; pretest as covariate) was used to measure the effects of constructivist informed and traditional pedagogy on student achievement. Student achievement was measured with a researcher-designed pretest, posttest, and delayed posttest. A significance difference was found on the science achievement posttest where the students receiving the traditional pedagogy scored higher than the students taught by the constructivist pedagogy. However, the scores of students receiving constructivist-informed pedagogy showed a slight increase on the delayed posttest, while the traditionally taught students' scores decreased, thus the difference in the achievement of the two groups was diminished over time. A repeated measures ANOVA was used to analyze the ancillary data from the Student Outcome Assessment. (p < .05) Among 51 students tested, those who received the constructivist informed pedagogy had higher retention, approaching significance of the biology concepts tested over time. Ancillary data was used to assist the interpretation of the assessment measurements. Using ratios of students' and teachers' scores of perceived constructivist attributes in their classroom appeared to be an effective way for teachers to compare student perceptions with their own.

Walters, Glenn D

2017-12-01

There is some consensus on the value of cognitive-behaviourally informed interventions in the criminal justice system, but uncertainty about which components are of critical value. To test the hypothesis that change in prisoners - criminal thinking and institutional misconduct - will both follow completion of a brief cognitive behavioural intervention. A one-group pre-test-post-test quasi-experimental design was used to assess change on the General Criminal Thinking (GCT) scale of the Psychological Inventory of Criminal Thinking Styles among 219 male prisoners completing a 10-week cognitive behavioural intervention, referred to as 'Lifestyle Issues'. Institutional misconduct was measured for 1 year prior to completion of the course and 2 years subsequently. Using variable-oriented analysis, post-test GCT scores were compared with change in prison conduct, controlling for the pre-test thinking scores. Calculations were repeated by using person-oriented analysis. Prisoners who displayed a drop in GCT scores between pre-test and post-test levels were significantly more likely to show a reduction in prison misconduct, whereas prison misconduct was likely to escalate among those who displayed a rise in criminal thinking scores from pre-test to post-test. These findings must still be regarded as preliminary, but taken together with other work and with cognitive behavioural theory, they suggest that development of more prosocial thinking and abilities may have an early beneficial effect on institutional behaviour. Their measurement may offer a practical way in which men could be assessed for readiness to return to the community. Copyright © 2017 John Wiley & Sons, Ltd. Copyright © 2017 John Wiley & Sons, Ltd.

Nurses can have an influence on primary and secondary prevention of skin cancer. Therefore, it is important to help them acquire knowledge and skills necessary to modify behavior in relation to skin cancers. The aim of this study was to examine effects of creating awareness through photographs and posters on knowledge and skills of skin self-examination in nursing students. The study had a quasi-experimental design with a pretest and a posttest in a single group. The study population included 249 last-year nursing students in Turkey. Non-probability sampling was used to reach the population. The study sample was composed of 201 students volunteering to participate in the study, and the response rate was 81 %. Of the students, 85.1 % (n = 171) were female and the mean age of the students was 22.18 ± 0.78 years. Of the students, 94.5 % did not know the asymmetry, border, color, diameter, evolution (ABCDE) criteria on the pretest, but this rate decreased to 20.9 % on the posttest. The mean score for knowledge of symptoms of skin cancer was 10.95 ± 1.37 on the pretest and 11.48 ± 0.90 on the posttest. There was a significant linear increase in the scores for knowledge of the symptoms (F = 7.874, p < 0.001) after the intervention with photographs and posters. The students were observed to learn the ABCDE criteria and had increased knowledge of skin cancer symptoms after the intervention using photographs and posters. Photographs and posters are effective tools which can be used to increase awareness of skin self-examination.

Women may experience significant stress during pregnancy, and antenatal care and education provide a means to address this. E-health, the use of computer and information technology for health care, has been incorporated into antenatal care and education, but e-health has not been evaluated for its usefulness in addressing stress. The objective of this study was to investigate the effectiveness of a web-based antenatal care and education system on pregnancy-related stress, general self-efficacy, and satisfaction with antenatal care. A quasi-experimental design enrolled pregnant women at 16 to 24 weeks' gestation with a low-risk pregnancy. Women in the control group (n = 67) received routine antenatal care; women in the experimental group (n = 68) also received a web-based antenatal care and education program in the second trimester. Pregnancy stress and general self-efficacy were assessed at study entry and again at 36 to 38 weeks' gestation; satisfaction with care was assessed at the study endpoint. When the pretest scores were controlled, the women in the experimental group reported significantly lower pregnancy-related stress (F = 12.9, P < .001) and significantly higher self-efficacy (F = 17.61, P < .001) than did the women in the control group. Women in the experimental group reported lower pregnancy-related stress (t = 5.09, P < .001) and a higher general self-efficacy (t = -3.17, P = .001) at posttest compared to pretest. However, the women in the control group reported a lower general self-efficacy at posttest compared to pretest (t = 2.86, P = .006). Women in the experimental group reported significantly higher satisfaction levels with antenatal care than those in the control group. A web-based antenatal care and education system can improve pregnancy-related stress and general self-efficacy among pregnant women. Integrating health care with web-based or internet-based interventions may improve the quality of antenatal care. © 2018 by the American College of Nurse-Midwives.

The study was conducted based on teaching and learning problems led by conventional method that had been done in the process of learning science. It gave students lack opportunities to develop their competence and thinking skills. Consequently, the process of learning science was neglected. Students did not have opportunity to improve their critical attitude and creative thinking skills. To cope this problem, the study was conducted using Project-Based Learning model through inquiry-based science education about environment. The study also used an approach called Sains Lingkungan and Teknologi masyarakat - “Saling Temas” (Environmental science and Technology in Society) which promoted the local content in Lampung as a theme in integrated science teaching and learning. The study was a quasi-experimental with pretest-posttest control group design. Initially, the subjects were given a pre-test. The experimental group was given inquiry learning method while the control group was given conventional learning. After the learning process, the subjects of both groups were given post-test. Quantitative analysis was performed using the Mann-Whitney U-test and also a qualitative descriptive. Based on the result, environmental literacy skills of students who get inquiry learning strategy, with project-based learning model on the theme soil washing, showed significant differences. The experimental group is better than the control group. Data analysis showed the p-value or sig. (2-tailed) is 0.000 <α = 0.05 with the average N-gain of experimental group is 34.72 and control group is 16.40. Besides, the learning process becomes more meaningful.

Depression is a worldwide public health problem that requires the attention of qualified health professionals. The training of skilled nurses is a challenge for nursing instructors due to the complexity of this pathology. The aim was to analyse the declarative and argumentative knowledge acquired about depression by students receiving traditional expository instruction versus students receiving problem-based learning instruction. Quasi-experimental study with pre-test and post-test design in experimental and control group to measure differences in the improvement of declarative and argumentative knowledge. Non parametric tests were used to compare the scores between the experimental group and the control group, and between the pre-test and post-test in each group. 114 students participated in the study. Implementation of the study took place during the 2014-2015 academic year in the third year of the Nursing undergraduate degree courses in the University of the Basque Country (UPV/EHU) as part of the Mental Health Nursing subject. The data indicated that there were no statistically significant differences between the two methodologies in regard to declarative knowledge in the care of patients with depression. Nevertheless, the argumentative capacity of the experimental group improved significantly with the problem-based learning methodology (p=0.000). The results of the implementation indicated that problem-based learning was a satisfactory tool for the acquisition of argumentative capacity in depression nursing care. Still, working examples of teaching sequences that bridge the gap between general clinical practice and classroom practice remain an important goal for continuing research in nursing education.

To evaluate a systematic treatment programme developed by the researcher that targeted aspects of visual functioning affected by visual field deficits following stroke. The study design was a non-equivalent control (conventional) group pretest-posttest quasi-experimental feasibility design, using multisite data collection methods at specified stages. The study was undertaken within three acute hospital settings as outpatient follow-up sessions. Individuals who had visual field deficits three months post stroke were studied. A treatment group received routine occupational therapy and an experimental group received, in addition, a systematic treatment programme. The treatment phase of both groups lasted six weeks. The Nottingham Adjustment Scale, a measure developed specifically for visual impairment, was used as the primary outcome measure. The change in Nottingham Adjustment Scale score was compared between the experimental (n = 7) and conventional (n = 8) treatment groups using the Wilcoxon signed ranks test. The result of Z = -2.028 (P = 0.043) showed that there was a statistically significant difference between the change in Nottingham Adjustment Scale score between both groups. The introduction of the systematic treatment programme resulted in a statistically significant change in the scores of the Nottingham Adjustment Scale.

To check the effectiveness of a mindfulness development meditation technique on stress and anxiety in a group of primary-care physicians. Quasi-experimental with pretest/posttest/follow-up measurements in a control group and an experimental group. SITE: University of Almeria. 38 primary-care physicians enrolled in a Teaching Aptitude Course (CAP). An experimental group and a control group were formed with 19 participants in each. The experimental group took a psycho-educational meditation program for training and practice in mindfulness. The Perceived Stress Scale (PSS), the Strain Questionnaire and the State-Trait Anxiety Questionnaire were used to measure stress and anxiety levels. A comparative statistical analysis was performed using the Mann-Whitney non-parametric U test, finding a significant reduction in all the primary-care physician stress and anxiety variables in the experimental group compared to the control group in pretest-posttest and follow-up tests. The results of this study support the effectiveness of mindfulness development meditation techniques in decreasing stress and anxiety in primary-care physicians. Nevertheless, the study shows various limitations that would have to be corrected in successive studies to bring more validity to the results. Copyright © 2009 Elsevier España, S.L.

This quasi-experimental study examined the effects of cognitive-behavioral therapy (CBT) to control depression, anger, and self-control in soldiers from South Korea. Using a pretest-posttest design, the sample was composed of an experimental group (n = 16) and a control group (n = 12). The experimental group participated in four sessions of CBT. No significant differences were found between the groups with regard to demographic characteristics. Changes in the variables after the intervention were analyzed using Wilcoxon's signed-rank sum test. The depression scores decreased significantly after the intervention (z = -3.05, p = 0.002); whereas, the scores of state-trait anger and self-control did not change. In the control group, none of the outcome variable scores changed significantly. The results indicate that the developed CBT program might be an effective modality to decrease the depression of soldiers who are in military service. Copyright 2014, SLACK Incorporated.

Background Undergraduate nursing education standards include acquisition of knowledge of ethics principles and the prevalence of health-care ethical dilemmas mandates that nursing students study ethics. However, little research has been published to support best practices for teaching/learning ethics principles. Purpose This study sought to determine if participation in an ethics consultation simulation increased nursing students' knowledge of nursing ethics principles compared to students who were taught ethics principles in the traditional didactic format. Methods This quasi-experimental study utilized a pre-test/post-test design with randomized assignment of students at three universities into both control and experimental groups. Results Nursing students' knowledge of nursing ethics principles significantly improved from pre-test to post-test ( p = .002); however, there was no significant difference between the experimental and control groups knowledge scores ( p = .13). Conclusion Further research into use of simulation to teach ethics principles is indicated.

The effects of computer simulation versus hands-on dissection and the placement of computer simulation within the learning cycle on student achievement and attitude

NASA Astrophysics Data System (ADS)

Hopkins, Kathryn Susan

The value of dissection as an instructional strategy has been debated, but not evidenced in research literature. The purpose of this study was to examine the efficacy of using computer simulated frog dissection as a substitute for traditional hands-on frog dissection and to examine the possible enhancement of achievement by combining the two strategies in a specific sequence. In this study, 134 biology students at two Central Texas schools were divided into the five following treatment groups: computer simulation of frog dissection, computer simulation before dissection, traditional hands-on frog dissection, dissection before computer simulation, and textual worksheet materials. The effects on achievement were evaluated by labeling 10 structures on three diagrams, identifying 11 pinned structures on a prosected frog, and answering 9 multiple-choice questions over the dissection process. Attitude was evaluated using a thirty item survey with a five-point Likert scale. The quasi-experimental design was pretest/post-test/post-test nonequivalent group for both control and experimental groups, a 2 x 2 x 5 completely randomized factorial design (gender, school, five treatments). The pretest/post-test design was incorporated to control for prior knowledge using analysis of covariance. The dissection only group evidenced a significantly higher performance than all other treatments except dissection-then-computer on the post-test segment requiring students to label pinned anatomical parts on a prosected frog. Interactions between treatment and school in addition to interaction between treatment and gender were found to be significant. The diagram and attitude post-tests evidenced no significant difference. Results on the nine multiple-choice questions about dissection procedures indicated a significant difference between schools. The interaction between treatment and school was also found to be significant. On a delayed post-test, a significant difference in gender was found on the diagram labeling segment of the post-test. Males were reported to have the higher score. Since existing research conflicts with this study's results, additional research using authentic assessment is recommended. Instruction should be aligned with dissection content and process objectives for each treatment group, and the teacher variable should be controlled.
Using a retrospective pretest instead of a conventional pretest is replacing biases: a qualitative study of cognitive processes underlying responses to thentest items.

The thentest design aims to detect and control for recalibration response shift. This design assumes (1) more consistency in the content of the cognitive processes underlying patients' quality of life (QoL) between posttest and thentest assessments than between posttest and pretest assessments; and (2) consistency in the time frame and description of functioning referenced at pretest and thentest. Our objective is to utilize cognitive interviewing to qualitatively examine both assumptions. We conducted think-aloud interviews with 24 patients with cancer prior to and after radiotherapy to elicit cognitive processes underlying their assessment of seven EORTC QLQ-C30 items at pretest, posttest and thentest. We used an analytic scheme based on the cognitive process models of Tourangeau et al. and Rapkin and Schwartz that yielded five cognitive processes. We subsequently used this input for quantitative analysis of count data. Contrary to expectation, the number of dissimilar cognitive processes between posttest and thentest was generally larger than between pretest and posttest across patients. Further, patients considered a range of time frames when answering the thentest questions. Moreover, patients' description at the thentest of their pretest functioning was often not similar to that which was noted at pretest. Items referring to trouble taking a short walk, overall health and QoL were most often violating the assumptions. Both assumptions underlying the thentest design appear not to be supported by the patients' cognitive processes. Replacing the conventional pretest-posttest design with the thentest design may simply be replacing one set of biases with another.

Through its ability to address and remove fear and misunderstanding and the resulting sexual reluctance and related problems, pre-marital sexual education and counselling can contribute to sexual satisfaction. This quasi-experimental research conducted in a pre-test-post-test control group design aimed to examine the effectiveness of nursing interventions on a premarital counselling program and its impacts on the sexual satisfaction of couples (36 couples in the experimental group and 35 couples in the control group). Although no difference was detected between the experimental and control groups in terms of the level of knowledge on pre-test point averages, the difference between them in terms of post-test knowledge gain averages was statistically significant. Approval rates for sexual myths in the pre-test were 27.87% in the experimental group and 37.03% in the control group; in the post-test they were 23.51% and 36.66% respectively. In the experimental group, 80.6% of the women and 63.9% of the men, and in the control group, 77.1% of the women and 71.4% of the men were established as having a problem-free sexual life. It was also discovered that levels of sexual satisfaction were shown to be higher among women and men in the experimental group who had attended premarital sexual counselling education than the women and men in the control group. A recommendation to encourage engaged couples to attend premarital sexual counselling is made based on the findings. It is thought that an intervention plan prepared within the framework of the Information, Motivation, Behavioural Skills theoretical model will help nurses guide recently-married couples to greater sexual satisfaction.

Breast cancer associates with severs severe distress and stress. Since Because of that, the stress management program can train necessary skills to cope with stress; therefore, the current study investigates the effectiveness of stress management on enhancement of quality of life. The aim of the current study is to examine the effectiveness of stress management model in quality of life for breast cancer patients. This research is a quasi-experimental study with pre and post-tests. The 21 subjects were selected from cancer institute of Imam Khomeini in Tehran in 2014. The participants were allocated to two matched groups based on their pre-test scores. They were assigned randomly to the control and experimental groups. Stress management was conducted with the experimental group during 10 sessions. Then the questionnaire was administered at post-test. Statistical analysis was conducted by using the independent t-test and analysis of variance. The research instrument was the core quality of life questionnaire QLQ-C30. The results of the independent t-test showed that there is a significant difference between the pretest and post-test scores in the experimental group (P < 0.05). Also, there is no significant difference between means of quality of life subscales and socio demographic of the patients such as; age, education and disease stage (P < 0.05). The results indicate that stress management can change the irrational and distortion thoughts. So, it enhances the quality of life in breast cancer patients.

Physical stress and mental stress are increasingly common phenomena in our rapidly changing and stressful modern society. Research has found meditation to produce positive and demonstrable stress reduction effects on brain and immune functions. This study is grounded in traditional Chinese philosophical mores that teach a process summarized by the keynote activities of "calm, still, quiet, consider, and get" and the potential of this process to reduce stress in adolescents. The purpose of this study was to examine the effects of meditation on the physical and mental health of junior college students. This research employed a quasi-experimental design. Participants included 242 freshmen from a junior college in Taiwan selected using a convenience sampling technique. Participants were then randomly separated into experimental (n = 119) and control (n = 123) groups. The project duration was 18 weeks, during which the experimental group received 2 hours of meditation treatment per week, for a total of 36 hours. Both groups completed pretest and posttest Life Adaptation Scale forms, which included questionnaires addressing information on physical and mental distress and positive and negative coping strategies. Data were analyzed using analysis of covariance. Findings showed that the effect of the experiment treatment was significant when student physical and mental distress pretest scores were controlled. Physical and mental symptoms in the experimental group were lower than those in the control group. Meditation can help students to adapt to life stressors. This study also provides support for traditional Chinese wisdom, which promotes meditation as one way to improve health.

The objectives of educational instruction on the rational use of medication are to teach students about frequent pharmaceutical applications, dosage calculations, observation of adverse side effects and patient training. A simulation project was used in nursing education/medical staff education to effectively gain knowledge and skills. In this study, our first aim was to investigate the effect of using a simulated patient as a teaching method on the performance of students in medication administration. Our second aim was to explore the students' views on the simulated patient teaching method in terms of the skills acquired in administering medication. The study was designed and carried out as a quasi-experimental investigation in Turkey between September 2011 and December 2011. The participants in the study were senior nursing students at a nursing school in Turkey. The data from eighty-five nursing students were obtained both at pretest and posttest. The views of all eighty-two students regarding a course on the rational use of medications were taken into consideration. Simulated patients were used throughout the entire course. An objectively constructed evaluation form (OCEF) was administered both at pretest and posttest to obtain participant feedback on a course on the rational use of medication. Descriptive statistics and a paired sample t-test were used in the data analyses. The mean pre-test score on the evaluation form was 24.02 ± 16.06, whereas the mean post-test score was 54.28 ± 14.54. Therefore, there was a statistically significant difference between the mean pre- and post-test scores (p<0.01; t=14.35). The use of a simulated patient in a course on the rational use of medication proved effective. Furthermore, the students gave positive feedback regarding the use of the simulated patient as a teaching method. Copyright © 2012 Elsevier Ltd. All rights reserved.

2008-10-01

The effectiveness of a spirit at work program in long-term care was evaluated using a quasi-experimental, pretest-posttest design. These findings, along with focus group results, provide strong support that the program increased spirit at work, job satisfaction, organizational commitment, and organizational culture (particularly teamwork and morale), leading to a reduction in turnover and absenteeism--two major concerns in the long-term care sector. This study suggests that implementation of a spirit at work program is a relatively inexpensive way to enhance the work satisfaction of employees, increase their commitment to the organization (thus reducing turnover and absenteeism), and ultimately improve the quality of resident care.

The purpose of this study was to increase type 2 diabetes (T2DM) awareness and decrease T2DM risk factors by examining effectiveness of a modified version of the Centers for Disease Control and Prevention (CDC) Diabetes Prevention Program (DPP) with adolescents. A quasi-experimental one-group, pretest/posttest design was used to determine impact of the modified DPP on adolescents. Study intervention was incorporated into the health education curriculum at a public charter school and implemented over 11 weeks. Study sample included primarily African-American and Hispanic adolescents (N = 101) aged 13-18 attending the public charter school in a New Jersey urban community. Instrumentation included valid, reliable measures of self-efficacy for healthy eating, physical activity, food knowledge, and healthy food choices. Participants' pretest/posttest waist circumference and body mass index (BMI) were collected. Outcomes revealed significant (p < .001) increase in participants' food knowledge, self-efficacy for choosing healthy foods and performing physical activity, healthy food choices, and amount of weekly aerobic exercise. Reductions in BMI and waist circumference were statistically significant (p < .05). A modified DPP adapted for adolescents' learning needs lowered risk for T2DM. Implications for clinical practice, education, and research are posed. © 2017 Wiley Periodicals, Inc.

This study is a first-level evaluation of a family intervention targeted at adolescents with social, emotional and behavioural difficulties (SEBD) attending Child and Adolescent Mental Health Services (CAMHS) in Ireland. It is a combined implementation of the Working Things Out adolescent programme and the Parents Plus Adolescent Programme (WTOPPAP). A total of 93 adolescents aged 11-17 years (M = 14.64, SD = 1.31; 39% male) and their parents took part in the study. The study used a quasi-experimental One-Group Pretest-Posttest design to assess change from pre- to post-intervention using the Strengths and Difficulties Questionnaire, the McMaster General Functioning Scale, Goal Attainment, Parent Stress Scale and the Kansas Parenting Satisfaction Scale. Both parent- and adolescent-rated goal attainment and general family functioning improved from pre- to post-intervention. Parents also rated their satisfaction with parenting as having significantly improved. Adolescent-rated emotional difficulties significantly improved for the overall sample and parent-rated child total difficulties for female adolescents significantly improved from pre-test to post-test. Parents of female adolescents also reported a significant drop in parental stress. These findings indicate that the WTOPPAP may be an effective intervention for adolescents with SEBD, particularly females, and their parents. Further implications are discussed.

Objectives We evaluated a community-based intervention to promote safe motherhood, focusing on knowledge and behaviors that may prevent maternal mortality and birth complications. The intervention aimed to increase women’s birth preparedness, knowledge of birth danger signs, use of antenatal care (ANC) services, and delivery at a health facility. Methods Volunteers from a remote rural community in Northern Eritrea were trained to lead participatory educational sessions on safe motherhood with women and men. The evaluation used a quasi-experimental design (non-equivalent group pretest-posttest) including cross-sectional surveys with postpartum women (pretest N=466, posttest N=378) in the intervention area and in a similar remote rural comparison area. Results Women’s knowledge of birth danger signs increased significantly in the intervention area, but not in the comparison area. There was a significant increase in the proportion of women who had the recommended four or more ANC visits during pregnancy in the intervention area (from 18% to 80%, p<.001); while this proportion did not change significantly in the comparison area (from 53% to 47%, p=0.194). There was a greater increase in delivery in a health facility in the intervention area. Conclusions Participatory sessions led by community volunteers can increase safe motherhood knowledge and encourage use of essential maternity services. PMID:21323845
Self-reflection, gender and science achievement

Shoop, Kathleen A.

Drawing on socio-cognitive learning theory, this study compared achievement scores of 134 male and female high school biology students randomly assigned to groups which either used self-reflection, used self-reflection and received feedback, or did not self-reflect. Following a pretest, the teacher provided self-reflection strategy instruction to students in the two intervention groups and then subsequently provided in-class self-reflection time for these groups. The posttest concluded the unit; the retention measure was five weeks later. A quasi-experimental 3 x 3 x 2 (time x intervention x gender) factorial repeated-measures control group design was used for this study; a repeated measures ANOVA and several one-way ANOVA's were used to answer the research questions. Results from the repeated-measures ANOVA revealed significant results for Time and Time x Intervention, with the reflection group demonstrating significantly lower gains from pretest to posttest than the other two groups. The ANOVA examining differences between those who reflected and those who reflected and received feedback provided significant results with similar results for the difference between the control group and the reflection group. For teachers and students this study provides several areas of practical significance. Primarily, teachers may find lower student achievement if students regularly self-reflect but do not receive feedback for their reflection.

Dental hygiene students must embody effective critical thinking skills in order to provide evidence-based comprehensive patient care. The problem addressed in this study it was not known if and to what extent concept mapping and reflective journaling activities embedded in a curriculum over a 4-week period, impacted the critical thinking skills of 22 first and second-year dental hygiene students attending a community college in the Midwest. The overarching research questions were: what is the effect of concept mapping, and what is the effect of reflective journaling on the level of critical thinking skills of first and second year dental hygiene students? This quantitative study employed a quasi-experimental, pretest-posttest design. Analysis of Covariance (ANCOVA) assessed students' mean scores of critical thinking on the California Critical Thinking Skills Test (CCTST) pretest and posttest for the concept mapping and reflective journaling treatment groups. The results of the study found an increase in CCTST posttest scores with the use of both concept mapping and reflective journaling. However, the increase in scores was not found to be statistically significant. Hence, this study identified concept mapping using Ausubel's assimilation theory and reflective journaling incorporating Johns's revision of Carper's patterns of knowing as potential instructional strategies and theoretical models to enhance undergraduate students' critical thinking skills. More research is required in this area to draw further conclusions. Keywords: Critical thinking, critical thinking development, critical thinking skills, instructional strategies, concept mapping, reflective journaling, dental hygiene, college students.

To evaluate and implement the WalkSafe Pre-Kindergarten Pedestrian Safety Curriculum. A quasi-experimental pretest-posttest design without a control group was used to measure children's pedestrian safety knowledge. Knowledge assessments consisting of multiple-choice and short-answer questions were administered pre- and post-curriculum implementation by classroom teachers. Knowledge assessments gauged prekindergarten students' knowledge of pedestrian safety activities prior to safety curriculum implementation and, again, after the students received the curriculum. A total of 605 children (aged 3- to 5-year) from 38 prekindergarten classrooms in 16 randomly selected elementary schools participated in the pedestrian safety education pilot program. Subjects were of multiethnic and diverse backgrounds from the Miami-Dade County Public School District. Of the 605 educated subjects, 454 children completed both pre- and posttests. A statistically significant difference was found between pretest knowledge (M = 5.49, SD = 1.54) and posttest knowledge (M = 6.64, SD = 1.35) assessment scores across all 454 subjects, t(452) = -16.22, p < .001, 95% CI [-1.29, -1.01]. Previous studies have shown that classroom-based training of children as young as 4 years old can yield significant improvements in traffic safety knowledge. The statistical findings of the WalkSafe Pre-Kindergarten Pedestrian Safety Curriculum revealed statistically significant improvements in pedestrian safety knowledge of these young children. Future research efforts will focus on longitudinal behavioral changes in these students and an increase in pedestrian safety behaviors (e.g., utilization of crosswalks or sidewalks).
A study to compare traditional and constructivism-based instruction of a high school biology unit on biosystematics

NASA Astrophysics Data System (ADS)

Saigo, Barbara Woodworth

The researcher collaborated with four high school biology teachers who had been involved for 2-1/2 years in a constructivism-based professional development experience that emphasized teaching for conceptual change and using classroom-based inquiry as a basis for making instructional decisions. The researcher and teachers designed a five-day instructional unit on biosystematics using two contrasting approaches, comprising the treatment variable. The "traditional" unit emphasized lecture, written materials, and some laboratory activities. The "constructivist" unit emphasized a specific, inquiry-based, conceptual change strategy and collaborative learning. The study used a quasi-experimental, factorial design to explore impact of instructional approach (the treatment variable) on student performance (the dependent variable) on repeated measures (three) of a biology concept test. Additional independent variables considered were gender, cumulative GPA, and the section in which students were enrolled. Scores on the biology concept test were compiled for the 3 constructivist sections (N = 44) and the 3 traditional sections (N = 42). Analysis of Covariance (ANCOVA) was applied. The main findings in regard to the primary research question were that instructional approach did not have a significant relationship to immediate post test scores or gain, but that one month after instruction students in the constructivist group demonstrated less loss of gain than those in the traditional group; i.e., their longer-term retention was greater. Also, GPA*instructional approach effects were detected for post-post-test gain. GPA and gender were significantly associated with pre-test, post-test, and post-post scores; however, in terms of change (gain) from pre-test to post-test and pre-test to post-post-test, GPA and gender were not significant effects. Section was a significant effect for all three tests, in terms of both score and gain. Gender*section effects were detected for post-test gain and post-post-test scores.

The present research was conducted to study the effect of play therapy on reducing behavioral problems of children with oppositional defiant disorder. Using multistage cluster sampling, regions 6, 7, and 8 in Tehran were selected. Among kindergartens of these areas, 3 kindergartens which were supported by the welfare organization were randomly selected. Of all the pre-school children of these 3 kindergartens, 40 children who could have behavioral disorder, according to their teachers and parents, were carefully tested. Of them, 16 children who showed severe symptoms of oppositional defiant disorder, were selected via the results obtained from the child symptom inventory questionnaire (CSI-4), teacher's form, and a researcher-made self-control checklist, Then, the subjects were randomly divided into one control and one experimental group. This research is quasi-experimental, and is conducted using pre-test, post-test, and control group. Values of the calculated F for oppositional defiant disorder in control group and experimental group was meaningful after fixing the effect of pre-test (P<0/001). Therefore, a meaningful difference existed between the means of post-test scores of disobedience disorder in the experimental and control groups through the fixed effect of the pre-test effect. Comparison of adjusted means of the 2 groups showed that the mean of attention-deficit hyperactivity disorder (ADHD) in experimental group was lower than control group. Therefore, applying play therapy reduced severity of ADHD in those children in experimental group compared to those in control group who did not receive such instructions. Results of this research demonstrates that children's disobedience can be reduced by play therapy.
Interprofessional Education on Adverse Childhood Experiences for Associate Degree Nursing Students.

Olsen, Jeanette M; Warring, Sarah L

2018-02-01

The health impact of adverse childhood experiences (ACEs) is significant. Nurses need knowledge and must work in multidisciplinary teams to address this problem. This study examined the effects of an interprofessional education (IPE) activity with nonhealth care students on associate degree nursing (ADN) students' ACEs knowledge and perspectives on IPE. The mixed-methods approach used a quasi-experimental pretest-posttest design with an intervention and control group and thematic analysis of focus group data. Readiness for Interprofessional Learning scale mean scores indicated positive baseline IPE perspectives. Scores changed minimally for most measures in both the intervention and control groups on posttest. However, four major relevant themes related to ACEs knowledge and two related to interprofessional learning were identified. IPE with nonhealth care students is an effective way to teach ADN students about ACEs and infuse interprofessional learning in a nonuniversity setting. However, outcomes are best captured with qualitative data. [J Nurs Educ. 2018;57(2):101-105.]. Copyright 2018, SLACK Incorporated.

We tested the impacts of a professionally assisted peer-group intervention on Chilean health workers' HIV-related knowledge, attitudes, and behaviors using a quasi-experimental design with a pretest and 3-month posttest. Two Santiago suburbs were randomly assigned to the intervention or delayed intervention control condition. Five community clinics per suburb participated. Interested workers at the intervention (n = 262) and control (n = 293) clinics participated and completed both evaluations. At posttest, intervention clinic workers had higher knowledge and more positive attitudes regarding HIV, condoms, stigmatization, and self-efficacy for prevention. They reported more partner discussion about safer sex, less unprotected sex, and more involvement in HIV prevention activities in the clinic and the community, but they did not report fewer sexual partners or more standard precautions behaviors. Because of these positive impacts, the program will become a regular continuing education unit that can be used to meet health-worker licensing requirements.

2010-01-01

Although there is a strong evidence base for effective substance abuse prevention programs for youth, there is a need to facilitate the implementation and evaluation of these programs in real world settings. This study evaluates the effectiveness of adapted versions of an evidence-based prevention program, keepin’ it REAL (kiR), with alternative school students. Programs are often adapted when used in schools and other community settings for a variety of reasons. The kiR adaptations, developed during an earlier phase of this study, were created to make the curriculum more appropriate for alternative high school youth. The adaptations were evaluated using a quasi-experimental design in which questionnaires were administered at pretest, posttest, and follow-up, and focus groups were conducted at posttest. MANOVA analyses indicate significantly reduced intentions to accept alcohol and, for younger participants, reduced alcohol use. Focus group data support the need for age appropriate prevention content. The authors discuss implications for practitioners implementing prevention programs in schools. PMID:20622971

May, Douglas R; Luth, Matthew T

2013-06-01

Ethical conduct is the hallmark of excellence in engineering and scientific research, design, and practice. While undergraduate and graduate programs in these areas routinely emphasize ethical conduct, few receive formal ethics training as part of their curricula. The first purpose of this research study was to assess the relative effectiveness of ethics education in enhancing individuals' general knowledge of the responsible conduct of research practices and their level of moral reasoning. Secondly, we examined the effects of ethics education on the positive psychological outcomes of perspective-taking, moral efficacy, moral courage, and moral meaningfulness. To examine our research hypotheses, we utilized a pretest-posttest quasi-experimental design consisting of three ethics education groups (control, embedded modules, and stand-alone courses). Findings revealed that both embedded and stand alone courses were effective in enhancing participants' perspective-taking, moral efficacy, and moral courage. Moral meaningfulness was marginally enhanced for the embedded module condition. Moral judgment and knowledge of responsible conduct of research practices were not influenced by either ethics education condition. Contrary to expectations, stand alone courses were not superior to embedded modules in influencing the positive psychological outcomes investigated. Implications of these findings for future research and practice are discussed.
[Critical care nurse learning of continuous renal replacement therapy: the efficacy of a self-learning manual].

2011-02-01

Many nurses have difficulty learning to use the complex, non-traditional, and regularly-updated critical care equipment. Failure to use such equipment properly can seriously compromise treatment and endanger patient health and lives. New self-learning materials for novice nurses are necessary to provide essential and effective guidance as a part of formal nursing training. Such materials can enhance the capabilities of critical care nurses and, thus, improve the general quality of critical care. The purpose of this research was to develop a continuous renal replacement therapy (CRRT)-themed self-learning manual that would provide easily absorbed and understood knowledge in an easy-to-carry format for ICU nursing staff. This study also investigated CCRT skill learning efficacy. This study adopted a quasi-experimental design with pretests and posttests. Purposive sampling generated a sample of 66 critical care nurses currently working at one hospital in Taipei City. Participants submitted a completed self-assessment survey that rated their command of continuous renal replacement therapy before and after the self-learning manual intervention. Survey data were analyzed using SPSS Version 17.0 for Windows. The two major findings derived from the study included: (1) The mean response score from the self-assessment survey filled out after the intervention was 91.06 and 79.75 (SD = 9.49 and 11.65), respectively, for experimental and control groups. Such demonstrated significant difference. (2) The mean posttest score after the intervention for the experimental group was 91.06 ± 9.49. This represents a significant increase of 10.35 ± 10.35 over their mean pretest score (80.71 ± 11.82). The experimental group showed other significant differences in terms of the CRRT self-assessment survey posttest. Self-learning manuals may be introduced in nursing education as useful aids and catalysts to achieve more effective and satisfying learning experiences.

Peer counseling in a culturally specific adolescent pregnancy prevention program.

PubMed

Ferguson, S L

1998-08-01

This study evaluated the effects of peer counseling in a culturally specific adolescent pregnancy prevention program for African American females. A random pretest and multiple posttest experimental and comparison group design was used to obtain data on a sample of 63 female African American adolescents, ages 12 to 16, who lived in four public housing developments. Descriptive data and tests of significance revealed that none of the participants who received peer counseling became pregnant within three months of the intervention. Findings revealed a statistically significant increase in reproductive and other self-related knowledge topics among the experimental group when comparing pretest and eight-week posttest scores. Most participants had not had sexual intercourse; the average age of sexual onset was 12 years in the experimental group and 11 years in the controls. Designing and implementing culturally specific adolescent pregnancy prevention programs for adolescents younger than age 11 and/or before sexually active seems appropriate.

Volume, conservation and instruction: A classroom based solomon four group study of conflict

NASA Astrophysics Data System (ADS)

Rowell, J. A.; Dawson, C. J.

The research reported is an attempt to widen the applicability of Piagetian theory-based conflict methodology from individual situations to whole classes. A Solomon four group experimental design augmented by a delayed posttest, was used to provide a controlled framework for studying the effects of conflict instruction on Grade 8 students' ability to conserve volume of noncompressible matter, and to apply that knowledge to gas volume. The results, reported for individuals and groups, show the methodology can be effective, particularly when instruction is preceded by a pretest. Immediate posttest differences in knowledge of gas volume between spontaneous (pretest) conservers and instructed conservers of volume of noncompressible matter were no longer in evidence on the delayed posttest. This observation together with the effects of pretesting and of the instructional sequence are shown to have a consistent Piagetian interpretation. Practical implications are discussed.

Giacalone, Valarie A.

The purpose of this study was to examine the effects of an academic service learning project on ninth-grade students' science achievement and attitudes. A quasi-experimental, pretest-posttest design was used with four classes of one teacher in a rural school. The treatment was an Energy Fair service project. Two treatment classes that were chosen by random assignment (n = 58) were compared to two control classes (n = 64), who performed an alternative assignment. The Energy Fair was conducted for the elementary school students and on a limited basis for fellow students (peers). The academic effect was measured by a teacher-designed end-of-unit ecology test, with a subset of the questions on energy use. Psychological effects were measured by a self-esteem questionnaire, which measured both self-esteem and the satisfaction felt about one's self-esteem. Social effects were measured by three semantic differentials, one each for "adults," "peers," and "elementary students." The teacher was interviewed regarding her observations about the project. Written reflections from both the treatment and control groups were coded and analyzed. Pretest results were divided into thirds of high, medium, and low for all variables to search for the possibility of an attribute-treatment interaction. Analysis of covariance was used to reduce the possibility of pretest bias, to test for significant effects, and to test for a level by treatment interaction. Although the posttest means favored the experimental group, no statistically significant difference was found for academic results. No significant effect was found for either of the psychological measures. No change was found for the social results regarding "adults." A statistically significant effect was found for social results in the categories of "elementary students" and "peers." No statistically significant level by treatment interaction was found. Further research on the effects of academic service learning projects is needed at the middle school level, in all disciplines, and containing service of a longer duration and intensity.

This study was conducted to develop an e-Learning program that assists nursing students' clinical practice in operating room nursing and to examine the learning effects. Based on content and need analysis, 9 learning modules were developed for nursing care in operating rooms and with operating equipment. To verify the effects of the program, a quasi-experimental pretest-posttest control group design was employed. The participants in this study were 74 third-year nursing students (34 in the experimental and 40 in the control group) from a junior college in G-city, Korea, who were engaged in a one week clinical practicum in an operating unit. Frequencies, χ(2)-test and t-test with the SPSS program 17.0 were used to analyze the data. Knowledge was significantly higher in the experimental group compared to the control group (p=.018). However, there was no significant difference between the two groups in self-directed learning. The experimental group had significantly higher motivation toward learning, which was examined posttest only (p=.027). These results indicate that the implementation of an e-Learning program needs to be continued as an effective educational tool, but more research on the best way to implement e-Learning in students' practicum is needed.

This study examined the impact of an educational intervention (booklet distribution and lectures) on Singaporean nurses' provision of guidance to parents on the use of non-pharmacological methods of pain relief for their child's postoperative pain. Using a quasi-experimental one-group pre- and post-test study design, 134 and 112 registered nurses completed the questionnaires pre- and post-test, respectively. More than 75% of the nurses "always" guided parents to use breathing techniques, relaxation, positioning, comforting/reassurance, helping with activities of daily living, and creating a comfortable environment in the pretest and touch, presence, and distraction in addition to the aforementioned methods in the post-test. The nurses' provision of guidance to parents on all non-pharmacological methods increased, but statistically significant increases only were found in relation to massage and positive reinforcement. The results suggested that the educational intervention had some impact on nurses' provision of guidance to parents on the use of non-pharmacological methods of pain relief for children's postoperative pain. Continuing education in pain management should be provided to nurses in order to equip them with the knowledge to improve their practice. © 2011 Blackwell Publishing Asia Pty Ltd.
Evaluating the efficacy of a chemistry video game

Shapiro, Marina

A quasi-experimental design pre-test/post-test intervention study utilizing a within group analysis was conducted with 45 undergraduate college chemistry students that investigated the effect of implementing a game-based learning environment into an undergraduate college chemistry course in order to learn if serious educational games (SEGs) can be used to achieve knowledge gains of complex chemistry concepts and to achieve increase in students' positive attitude toward chemistry. To evaluate if students learn chemistry concepts by participating in a chemistry game-based learning environment, a one-way repeated measures analysis of variance (ANOVA) was conducted across three time points (pre-test, post-test, delayed post-test which were chemistry content exams). Results showed that there was an increase in exam scores over time. The results of the ANOVA indicated a statistically significant time effect. To evaluate if students' attitude towards chemistry increased as a result of participating in a chemistry game-based learning environment a paired samples t-test was conducted using a chemistry attitudinal survey by Mahdi (2014) as the pre- and post-test. Results of the paired-samples t-test indicated that there was no significant difference in pre-attitudinal scores and post-attitudinal scores.

This study examined the effects of a multicomponent exercise program on depression and quality of life in institutionalized older adults. A quasi-experimental pretest-posttest design was used. Participants were recruited from a publicly funded shelter home in Seremban, Negeri Sembilan Malaysia. The experimental group consisted of 23 volunteers 60 or older who performed 60 minutes of supervised exercise three times per week for 12 weeks. The control group consisted of 20 volunteers who continued with a sedentary lifestyle. At 12 weeks, the exercise group demonstrated an improvement in quality of life by 10.74% (p > 0.05) but not depression (-1.6%, p > 0.05). The control group demonstrated a decrease in both quality of life by 11.26% (p > 0.05) and level of depression by 17.7% (p > 0.05). This study suggests a multicomponent exercise program is a feasible intervention to improve quality of life in institutionalized older adults. Copyright 2010, SLACK Incorporated.

The study aims to determine the increasing of students' science literacy skills on content aspects and competency of science by using Integrated Science teaching materials based Socio-scientific Issues (SSI) for environmental pollution theme. The method used in the study is quasi-experiment with nonequivalent pretest and posttest control group design. The students of experimental class used teaching materials based SSI, whereas the students of control class were still using the usual textbooks. The result of this study showed a significant difference between the value of N-gain of experimental class and control class, whichalso occurred in every indicator of content aspects and competency of science. This result indicates that using of Integrated Science teaching materials based SSI can improve content aspect and competency of science and can be used as teaching materials alternative in teaching of Integrated Science.

2015-10-01

This study examined the effects of GeoGebra on mathematics performance of students with different spatial visualization. A qusai-experimental, pretest-posttest control group design was conducted. A total of 71 students from two intact groups were involved in the study. They were in two groups and each group was randonly assigned to the experimental group (36 students) and control group (35 students). A spatial visual test to identify students with high or low visualization, and a mathematics performance pre-test were administered at the initial stage of this study. A post-test was administered after 12 weeks of treatment using GeoGebra. Analyses of Covarion (ANCOVA) was used to adjust for the pre-test score. Findings showed that the group with access to GeoGebra achieved significantly better test scores in the posttest as compared to the group which followed the traditional teaching method. A two-way ANCOVA used to analyse the effect of students' spatial visualization on post-test performance showed that there was no effect. The results from this study suggested that using GeoGebra had helped the students to score better in the posttest. However, there is no significance difference on mathematics performances on students with difference types of spatial visualisastion. This study indicates that GeoGebra is useful in enhancing the teaching and learning of mathematics.

Regular physical activity is a health promotion and disease prevention behavior. Of all demographic groups, low-income women report the lowest levels of physical activity. The purpose of this study was to test an intervention aimed at reducing community environmental barriers to physical activity in low-income women. The research design was mixed methodology: (1) quantitative (quasi-experimental, pretest-posttest, cohort design in which no treatment partitioning was possible) and (2) qualitative (focus groups). The setting was a church-sponsored community center centrally located in a low-income urban neighborhood. The comparison group was recruited first followed by the intervention group to control for setting. The sample consisted of 104 women (comparison group, n = 53; intervention group, n = 51) between the ages of 18 and 63 years who were residents of neighborhoods served by the community center. No between-group differences were found for physical activity behavior. Significant between-group differences in cholesterol (P = .007) and perception of physical activity (P = .033) were observed. Significant intervention group increases from pretest to posttest were found related to advanced registered nurse practitioner support, friend support, and more positive physical activity environment at the community center. Qualitative data supported and enriched the quantitative data. Physical activity levels were not significantly different between the groups. In a sample of low-income women who have multiple barriers, improving attitudes, expanding their knowledge of community resources, and providing physical activity opportunities in their neighborhoods are important intermediate steps toward initiation and maintenance of regular physical activity.

Studies on leadership identity development through reflection with Team-Based Learning (TBL) in medical student education are rare. We assumed that reflection and feedback on the team leadership process would advance the progression through leadership identity development stages in medical students within the context of classes using TBL. This study is a quasi-experimental design with pretest-posttest control group. The pretest and posttest were reflection papers of medical students about their experience of leadership during their TBL sessions. In the intervention group, TBL and a team-based, guided reflection and feedback on the team leadership process were performed at the end of all TBL sessions. In the other group, only TBL was used. The Stata 12 software was used. Leadership Identity was treated both as a categorical and quantitative variable to control for differences in baseline and gender variables. Chi-square, t tests, and linear regression analysis were performed. The population was a cohort of 2015-2016 medical students in a TBL setting at Tehran University of Medical Sciences, School of Medicine. Teams of four to seven students were formed by random sorting at the beginning of the academic year (intervention group n = 20 teams, control group n = 19 teams). At baseline, most students in both groups were categorized in the Awareness and Exploration stage of leadership identity: 51 (52%) in the intervention group and 59 (55%) in the control group: uncorrected χ 2 (3) = 15.6, design-based F(2.83, 108) = 4.87, p = .003. In the posttest intervention group, 36 (36%) were in exploration, 33 (33%) were in L-identified, 20 (20%) were in Leadership Differentiated, and 10 (10%) were in the Generativity. None were in the Awareness or Integration stages. In the control group, 3 (20%) were in Awareness, 56 (53%) were in Exploration, 35 (33%) were in Leader Identified, 13 (12%) were in Leadership Differentiated. None were in the Generativity and Integration stages. Our hypothesis was supported by the data: uncorrected χ 2 (4) = 18.6, design-based F(3.77, 143) = 4.46, p = .002. The mean of the leadership identity in the pretest, intervention group equaled 1.93 (SD = 0.85) and the pretest, control group mean was 2.36 (SD = 0.86), p = .004. The mean of the posttest, intervention group was 3.04 (SD = 0.98) and posttest, control group mean was 2.54 (SD = 0.74), T = -4.00, design df = 38, p < .001, and adjusted on baseline and gender T = -8.97, design df = 38, p < .001. Reflection and feedback on the team leadership process in TBL advances the progression in stages of leadership identity development in medical students. Although the TBL strategy itself could have an impact on leadership identity development, this study demonstrates that when a reflection and feedback on leadership intervention are added, there is much greater impact.

The aim of this research was to find out whether 7E learning cycle under hypnoteaching model can enhance students’ mathematical problem-solving skill. This research was quasi-experimental study. The design of this study was pretest-posttest control group design. There were two groups of sample used in the study. The experimental group was given 7E learning cycle under hypnoteaching model, while the control group was given conventional model. The population of this study was the student of mathematics education program at one university in Tangerang. The statistical analysis used to test the hypothesis of this study were t-test and Mann-Whitney U. The result of this study show that: (1) The students’ achievement of mathematical problem solving skill who obtained 7E learning cycle under hypnoteaching model are higher than the students who obtained conventional model; (2) There are differences in the students’ enhancement of mathematical problem-solving skill based on students’ prior mathematical knowledge (PMK) category (high, middle, and low).

Objective: an appropriate psychological intervention to promote the level of the public health and mental well-being of nurses has a great importance. This investigation was aimed to study the effectiveness of stress management training on the psychological welfare of nurses in Imam Khomeini Hospital. Methodology: this study was quasi-experimental with pretest-posttest that used a control group. Hence, 40 of the nurses in Imam Khomeini Hospital were selected by using a convenience sampling method and placed in the experimental group and the control group. Both groups were pretested by using psychological well-being 84-question scale. Afterwards, the experimental group was trained for ten sessions under stress management skill exercise, and the check group got no intervention. Next, both societies were post-tested, and the acquired data were analyzed by using inferential and descriptive statistical methods accompanied by SPSS 21 software. Findings: the results indicated that stress management training significantly led to the promotion of psychological well-being in nurses (p < 0.001). Conclusion: it was found from the research that due to the high level of effectiveness of stress management training, its low cost, and its high acceptability by the patients, especially when it was performed in a group, had a significant positive impact on the promotion of psychological well-being in nurses.

This paper aims to report the design and test the effectiveness of an innovative caring teaching model based on the theoretical framework of caring in the Chinese context. Since the 1970's, caring has been a core value in nursing education. In a previous study, a theoretical framework of caring in the Chinese context is explored employing a grounded theory study, considered beneficial for caring education. A caring teaching model was designed theoretically and a one group pre- and post-test quasi-experimental study was administered to test its effectiveness. From Oct, 2009 to Jul, 2010, a cohort of grade-2 undergraduate nursing students (n=64) in a Chinese medical school was recruited to participate in the study. Data were gathered through quantitative and qualitative methods to evaluate the effectiveness of the caring teaching model. The caring teaching model created an esthetic situation and experiential learning style for teaching caring that was integrated within the curricula. Quantitative data from the quasi-experimental study showed that the post-test scores of each item were higher than those on the pre-test (p<0.01). Thematic analysis of 1220 narratives from students' caring journals and reports of participant class observation revealed two main thematic categories, which reflected, from the students' points of view, the development of student caring character and the impact that the caring teaching model had on this regard. The model could be used as an integrated approach to teach caring in nursing curricula. It would also be beneficial for nursing administrators in cultivating caring nurse practitioners.

This study examines the application of classical music backsound in mathematics learning. The method used is quasi experimental design nonequivalent pretest-posttest control group in elementary school students in Tasikmalaya city, Indonesia. The results showed that classical music contributed significantly to the mathematical intelligence of elementary school students. The mathematical intelligence shown is in the cognitive ability ranging from the level of knowledge to evaluation. High level mathematical intelligence is shown by students in reading and writing integers with words and numbers. The low level of mathematical intelligence exists in projecting the story into a mathematical problem. The implication of this research is the use of classical music backsound on learning mathematics should pay attention to the level of difficulty of mathematics material being studied.

This study evaluated the effectiveness of a computer-based cognitive retraining (CBCR) program on improving memory and attention deficits in individuals with a chronic acquired brain injury (ABI). Twelve adults with a chronic ABI demonstrating deficits in memory and attention were recruited from a convenience sample from the community. Using a quasi-experimental one-group pretest-posttest design, a significant improvement was found in both memory and attention scores postintervention using the cognitive screening tool. This study supported the effectiveness of CBCR programs in improving cognitive deficits in memory and attention in individuals with chronic ABI. Further research is recommended to validate these findings with a larger ABI population and to investigate transfer to improvement in occupational performance that supports daily living skills.

The purpose of this study was to examine the relationship between critical thinking and the use of concept mapping (CM) and problem-based learning (PBL) during care plan development. A quasi-experimental study with a pretest-posttest design was conducted using a convenience sample (n = 49) of first-semester undergraduate baccalaureate nursing students. Critical thinking was measured using the Holistic Critical Thinking Scoring Rubric. Data analysis consisted of a repeated measures analysis of variance with post hoc mean comparison tests using the Bonferroni method. Findings indicated that mean critical thinking at phase 4 (CM and PBL) was significantly higher, compared with phase 1 (baseline), phase 2 (PBL), and phase 3 (CM [p < 0.001]). The results support the utilization of nontraditional instructional (CM and PBL) methodologies in undergraduate nursing curricula. Copyright 2015, SLACK Incorporated.

We conducted a campus forest-walking program targeting university and graduate students during their lunchtime and examined the physical and psychological effects of the program. We utilized a quasi-experimental design with a control group and a pretest-posttest design. Forty-seven men (M = 25.5 ± 3.8 years) and 52 women (M = 23.3 ± 4.3 years) volunteered to participate (experimental group n = 51, control group n = 48). The intervention group participated in campus forest-walking program once a week for six weeks; they were also asked to walk once a week additionally on an individual basis. Additionally, participants received one lecture on stress management. Post-tests were conducted both just after the program ended and three months after. A chi-square test, t -test, and repeated measures analysis of variance were used to evaluate the effects of the program. Health promoting behaviors ( F = 7.27, p = 0.001, ES = 0.27) and parasympathetic nerve activity ( F = 3.69, p = 0.027, ES = 0.20) significantly increased and depression ( F = 3.15, p = 0.045, ES = 0.18) significantly decreased in the experimental group after the intervention compared to the control group. In conclusion, using the campus walking program to target students during their lunchtime is an efficient strategy to promote their physical and psychological health.

Background:Applying structural models is important to chemistry education at the upper secondary level, but it is considered one of the most difficult topics to learn. Purpose:This study analyses to what extent in designed lessons students learned to apply structural models in explaining the properties and behaviours of various materials. Sample:An experimental group is 27 Finnish upper secondary school students and control group included 18 students from the same school. Design and methods:In quasi-experimental setting, students were guided through predict, observe, explain activities in four practical work situations. It was intended that the structural models would encourage students to learn how to identify and apply appropriate models when predicting and explaining situations. The lessons, organised over a one-week period, began with a teacher's demonstration and continued with student experiments in which they described the properties and behaviours of six household products representing three different materials. Results:Most students in the experimental group learned to apply the models correctly, as demonstrated by post-test scores that were significantly higher than pre-test scores. The control group showed no significant difference between pre- and post-test scores. Conclusions:The findings indicate that the intervention where students engage in predict, observe, explain activities while several materials and models are confronted at the same time, had a positive effect on learning outcomes.

Objective The present research was conducted to study the effect of play therapy on reducing behavioral problems of children with oppositional defiant disorder. Method Using multistage cluster sampling, regions 6, 7, and 8 in Tehran were selected. Among kindergartens of these areas, 3 kindergartens which were supported by the welfare organization were randomly selected. Of all the pre-school children of these 3 kindergartens, 40 children who could have behavioral disorder, according to their teachers and parents, were carefully tested. Of them, 16 children who showed severe symptoms of oppositional defiant disorder, were selected via the results obtained from the child symptom inventory questionnaire (CSI-4), teacher's form, and a researcher-made self-control checklist, Then, the subjects were randomly divided into one control and one experimental group. This research is quasi-experimental, and is conducted using pre-test, post-test, and control group. Results Values of the calculated F for oppositional defiant disorder in control group and experimental group was meaningful after fixing the effect of pre-test (P<0/001). Therefore, a meaningful difference existed between the means of post-test scores of disobedience disorder in the experimental and control groups through the fixed effect of the pre-test effect. Comparison of adjusted means of the 2 groups showed that the mean of attention-deficit hyperactivity disorder (ADHD) in experimental group was lower than control group. Therefore, applying play therapy reduced severity of ADHD in those children in experimental group compared to those in control group who did not receive such instructions. Conclusion Results of this research demonstrates that children's disobedience can be reduced by play therapy. PMID:22952519

Caregivers in long-term care (LTC) facilities have to uphold a positive attitude toward the elderly, so they will be more willing to provide the elderly with care of higher quality. Theory of Gerotranscendence is a theory which can assist the elderly in developing more mature and intellectual state of mind. It is hoped that the caregivers who receive gerotranscendence education may apply its concept to the care for the elderly. To evaluate the effects of the gerotranscendence educational program on caregivers' gerotranscendence recognition, attitude towards aging, and behavioral intention towards caring for the elderly. A quasi-experimental design with repeated measures was conducted. A total of 41 caregivers in LTC facilities participated and completed the study. Participants were invited to participate in a 2-day gerotranscendence educational program, and measurement took place at baseline, the end of the program (post-test) and three months after the program (follow-up test). The research tools included Gerotranscendence Recognition Scale-Chinese version, Aging Attitude scale, and Caregivers' Behavioral Intention Scale. This study used GLM repeated measures to perform analysis. There was a statistically significant difference in three repeated measures of participants' gerotranscendence recognition and behavior intention toward caring for the elderly (p=.002, .002, respectively) but not in the aging attitude score (p=.21). The post hoc comparison showed that the scores of these two outcomes in the post-test were significantly higher than those in the pre-test (p=.000; .024). However, the scores in the follow-up test were almost the same as those in the pre-test. The gerotranscendence educational program had timely effects on caregivers' gerotranscendence recognition and behavioral intention towards aging, and so caregivers working in LTC facilities may require ongoing training in the gerotranscendence educational program to ensure that these positive effects remain strong.

Clinical education is vital to both the development of clinical self-efficacy and the integration of future nurses into health care teams. The dedicated education unit clinical teaching model is an innovative clinical partnership, which promotes skill development, professional growth, clinical self-efficacy, and integration as a team member. Blended clinical teaching models are combining features of the dedicated education unit and traditional clinical model. The aims of this study are to explore how each of three clinical teaching models (dedicated education unit, blended, traditional) affects clinical self-efficacy and attitude toward team process, and to compare the dedicated education unit model and blended model to traditional clinical. A nonequivalent control-group quasi-experimental design was utilized. The convenience sample of 272 entry-level baccalaureate nursing students included 84 students participating in a dedicated education unit model treatment group, 66 students participating in a blended model treatment group, and 122 students participating in a traditional model control group. Perceived clinical self-efficacy was evaluated by the pretest/posttest scores obtained on the General Self-Efficacy scale. Attitude toward team process was evaluated by the pretest/posttest scores obtained on the TeamSTEPPS® Teamwork Attitude Questionnaire. All three clinical teaching models resulted in significant increases in both clinical self-efficacy (p=0.04) and attitude toward team process (p=0.003). Students participating in the dedicated education unit model (p=0.016) and students participating in the blended model (p<0.001) had significantly larger increases in clinical self-efficacy compared to students participating in the traditional model. These findings support the use of dedicated education unit and blended clinical partnerships as effective alternatives to the traditional model to promote both clinical self-efficacy and team process among entry-level baccalaureate nursing students.

Ledger, Antoinette Frances

This study sought to examine whether collaborative concept mapping would affect the achievement, science self-efficacy and attitude toward science of female eighth grade science students. The research questions are: (1) Will the use of collaborative concept mapping affect the achievement of female students in science? (2) Will the use of collaborative concept mapping affect the science self-efficacy of female students? (3) Will the use of collaborative concept mapping affect the attitudes of females toward science? The study was quasi-experimental and utilized a pretest-posttest design for both experimental and control groups. Eighth grade female and male students from three schools in a large northeastern school district participated in this study. The achievement test consisted of 10 multiple choice and two open-response questions and used questions from state-wide and national assessments as well as teacher-constructed items. A 29 item Likert type instrument (McMillan, 1992) was administered to measure science self-efficacy and attitude toward science. The study was of 12 weeks duration. During the study, experimental group students were asked to perform collaborative concept map construction in single sex dyads using specific terms designated by the classroom teacher and the researcher. During classroom visitations, student perceptions of collaborative concept mapping were collected and were used to provide insight into the results of the quantitative data analysis. Data from the pre and posttest instruments were analyzed for both experimental and control groups using t-tests. Additionally, the three teachers were interviewed and their perceptions of the study were also used to gain insight into the results of the study. The analysis of data showed that experimental group females showed significantly higher gains in achievement than control group females. An additional analysis of data showed experimental group males showed significantly greater gains in achievement than experimental group females. The analysis of science self-efficacy data showed that neither experimental nor control group females increased their scores pre to posttest, both showed small decreases in scores. However, the posttest scores of the experimental group females were significantly higher than the posttest scores of the control group females. The analysis of the attitude toward science survey data showed that the scores of the experimental group females did not change from pre to posttest. However, scores of the control group females declined from pre to posttest. (Abstract shortened by UMI.)

Palmer, Joel C.

The purpose of this study was to examine the impact of planetarium experiences on students' understanding of phases of the moon and eclipses. This research employed a quasi-experimental design. Students from 12 classes in four different schools all in the same school district participated in the study. A total of 178 students from four teachers participated in the study. Data were collected using a researcher developed pretest and posttest. All students received classroom instruction based on the school district's curriculum. The experimental groups took the posttest after attending a 45-minute planetarium experience titled Moon Witch. The control groups took the posttest before attending the planetarium experience but after receiving an additional 45-minute lesson on phases of the moon and eclipses. The data were analyzed using the Statistical Package for Social Sciences (SPSS). An Analysis of Variance (ANOVA) was run to determine if there was variance among teachers' instructional practices. Since the results indicated there was no significant variance among teachers, the study sample was analyzed as a single group. An Independent Samples t Test for Means was run in SPSS for the study sample and each subgroup. Subgroups were African American, Hispanic, White, Male, Female, and Economically Disadvantaged. The results indicated that there was an improvement on mean gain scores for the experimental group over the control group for all students and each subgroup. The differences in mean gain scores were significantly higher for all students and for the African American, Female, and Economically Disadvantaged subgroups. An Independent Samples t Test for Means was run using SPSS for each of the three different sections of the pretest and posttest. The results indicated that most of the improvement was in Section 3. This section required students to manipulate photos of the phases of moon into correct order. This section required more spatial reasoning than Section 1, multiple-choice, or Section 2, essay. Results indicate that planetarium experiences improved students' understanding of phases of the moon and eclipses. There was evidence that this improvement was facilitated by the planetarium's ability to create visual representations that students would otherwise have to create mentally.

Objective Threats to external validity including pretest sensitization and the interaction of selection and an intervention are frequently overlooked by researchers despite their potential to significantly influence study outcomes. The purpose of this investigation was to conduct secondary data analyses to assess the presence of external validity threats in the setting of a randomized trial designed to promote mammography use in a high risk sample of women. Design During the trial, recruitment and intervention implementation took place in three cohorts (with different ethnic composition), utilizing two different designs (pretest-posttest control group design; posttest only control group design). Results Results reveal that the intervention produced different outcomes across cohorts, dependent upon the research design used and the characteristics of the sample. Conclusion These results illustrate the importance of weighing the pros and cons of potential research designs before making a selection and attending more closely to issues of external validity.

The research was conducted by a pretest and post-test conducted in a quasi-experimental design which aimed to determine effectiveness of Aggression Replacement Training (ART) on problem solving, anger and aggressive behaviour among adolescents with criminal attempts in Turkey. The study included 65 adolescents with criminal attempts (32 intervention, 33 control). There was no difference between the groups in terms of average age (16.13±1.10 in the experimental group and 16.21±0.89 in the control group). After the intervention, the experimental group showed significantly decreased Trait Anger levels (t=1.906; P=0.033), increased Anger Control scores (t=2.522; P=0.008), decreased Physical Aggression scores (t=1.925; P=0.031), decreased Hostility scores (t=2.496; P=0.009), increased Social Problem Solving total scores (t=2.937; P=0.005). Increased Anger Control scores were found to be significant when compared with the control group (t=2.273, P=0.026). These results showed that ART was effective on problem solving, anger and aggressive behaviour and can be used to develop positive behaviours among adolescents with criminal attempts.

This study measured skill improvement in prewriting skills, kindergarten readiness, first-name writing, and handwriting-nonspecific fine motor skills of students at Head Start who participated in Handwriting Without Tears-Get Set for School (HWT-GSS) programming. We conducted a two-group, nonrandomized controlled trial using a pretest-posttest design at a rural Head Start. The effectiveness of adding the HWT-GSS curriculum in one preschool classroom was compared with a control classroom. On posttesting, the experimental group made significant improvements compared with the control group in prewriting, kindergarten readiness, and fine motor skills. Both groups made significant improvements between pretesting and posttesting in prewriting, first name writing, and school readiness. Adding HWT-GSS to the Head Start program would be beneficial in improving handwriting readiness skills.

[Purpose] Instrument Assisted Soft Tissue Mobilization (IASTM) is a form of manual therapy. Despite its growing popularity and an increasing number of patients receiving IASTM each year, there is a lack of high-level evidence to elucidate its therapeutic mechanisms and to support its clinical applications. The purpose of this research project was to determine the effects of IASTM on activities of mechanosensitive neurons in skin. [Subjects and Methods] Twenty-three subjects, 9 females and 14 males, mean age 25.7 (SD 6.4) years old were recruited through a convenience sampling on the university campus. The study design was a quasi-experimental study using single group pretest-posttest design. The activities of mechanosensitive neurons were measured before and after the application of IASTM. [Results] The mean 2-point discrimination was 40.2 (SD 9.4) mm before IASTM and increased to 44.9 (SD 12.0) mm after IASTM. The increase was statistically significant pre and post IASTM. The mean pain threshold was 18.2 (SD 6.6) lb and increased slightly to 18.7 (SD 6.8) lb after IASTM; however, no statistical significance was found pre and post IASTM. [Conclusion] The data indicates that IASTM changes the neural activities in 2-point discrimination but not in pain threshold.

This article describes a quasi-experimental evaluation of a community-based, culturally and ecologically tailored HIV prevention intervention for Mexican American female adolescents grounded in the AIDS risk reduction model. A total of 378 Mexican American female adolescents (mean age = 15.2) participated in either the nine-session SHERO's (a female-gendered version of the word hero) intervention or a single session information-only HIV prevention intervention. Assessment data were collected at pretest, posttest, and 2-month follow up. Significant improvements across all time points were revealed on measures of self-esteem, condom attitudes, beliefs regarding a woman's control of her sexuality, beliefs regarding sexual assault, perceived peer norms, and HIV/AIDS and STI knowledge. At posttest SHERO's participants were more likely to carry condoms and to report abstaining from vaginal sex in the previous 2 months; and at 2-month follow up they reported using condoms more often in the preceding 2 months and planned on using them more frequently in the coming 2 months. Findings support the development of community-based adolescent HIV prevention interventions that address culturally specific ecological factors.

2017-10-01

Patients with endotracheal intubation often experience anxiety because they are unable to express their needs freely. However, the family members of these patients are able to provide encouragement, comfort, and substantive support. The aims of the present study were: (1) to compare the anxiety scores, vital signs, and incidence of unplanned extubation (UE) between the two comparison groups; (2) to compare the differences in vital signs before and after the intervention in the experimental group; and (3) to explore the satisfaction of patients in the experimental group with the intervention. A quasi-experimental, pretest-posttest design was carried out. A convenience sampling was adopted to recruit patients with endotracheal intubation in intensive care units (ICUs). The experimental group listened to the UE-prevention reminders of their family members for three times a day for 4 days. The control group was provided with usual care. (1) No significant difference was observed in the anxiety scores between the two groups (t = -1.282, p = .205). (2) A repeated-measures analysis found no significant difference in vital signs, taken nightly at 10 p.m., between the experimental and control groups (p > .05). (3) The experimental group registered significantly lower heart rates, systolic blood pressure, diastolic blood pressure, and mean arterial pressure after the conclusion of the intervention (p < .05). However, no significant pre-test / posttest difference in breathing rate was observed for this group. (4) A large majority (89%) of the experimental group expressed satisfaction with the intervention treatment program. The present study, which used a DVD of family reminders encouraging and reminding patients about intubation safety, achieved a very high level of patient satisfaction and reduced their anxiety-related vital signs. The results may serve as a reference for providing intervention treatment to patients with endotracheal intubation in ICUs.

This study was conducted to develop an Empowerment Education Program (EEP) for kidney transplant patients and to test the program's effects on uncertainty, self-care ability, and compliance. The research was conducted using a nonequivalent control group with a pretest-posttest design. The participants were 53 outpatients (experimental group: 25, control group: 28) who were receiving hospital treatment after kidney transplants. After the pre-test, patients in the experimental group underwent a weekly EEP for six weeks. The post-test was conducted immediately after, and four weeks after the program's completion in the same manner as the pre-test. For the control group, we conducted a post-test six and ten weeks after the pre-test, without and program intervention. A repeated measure ANOVA was performed to compare the change scores on main outcomes. Uncertainty was significantly lower in the experimental group than in the control group, both immediately after (t=-3.84, p=<.001) and 4 weeks after (t=-4.51 p=<.001) the program, whereas self-care ability (t=5.81, p=<.001), (t=5.84, p=<.001) and compliance (t=5.07, p=<.001), (t=5.45, p=<.001) were significantly higher. Kidney transplant patients who underwent an EEP showed a decrease in uncertainty and an improvement in self-care ability and compliance. Thus, our findings confirmed that an EEP can be an independent intervention method for improving and maintaining the health of kidney transplant patients. © 2017 Korean Society of Nursing Science

The present study examined the comparative effects of a prediction/discussion-based learning cycle, conceptual change text (CCT), and traditional instructions on students' understanding of genetics concepts. A quasi-experimental research design of the pre-test-post-test non-equivalent control group was adopted. The three intact classes, taught by the same science teacher, were randomly assigned as prediction/discussion-based learning cycle class (N = 30), CCT class (N = 25), and traditional class (N = 26). Participants completed the genetics concept test as pre-test, post-test, and delayed post-test to examine the effects of instructional strategies on their genetics understanding and retention. While the dependent variable of this study was students' understanding of genetics, the independent variables were time (Time 1, Time 2, and Time 3) and mode of instruction. The mixed between-within subjects analysis of variance revealed that students in both prediction/discussion-based learning cycle and CCT groups understood the genetics concepts and retained their knowledge significantly better than students in the traditional instruction group.

2010-01-01

Very little prospective, randomized, experimental research exists on the use of simulation as a teaching method, and no studies have compared the effects of 2 strategies of using the Human Patient Simulator (HPS) and a CD-ROM on the management of patients exposed to chemical agents. A prospective, pretest-posttest experimental, mixed design (within and between) was used to determine if there were statistically significant differences between educational strategies using HPS, CD-ROM, and a control group in the care of patients exposed to chemical agents. Care was operationally defined as the score on the Management of Chemical Warfare Patients Performance (MCWPP) instrument. Participants included active duty and reserve military nurses (n=92). They were randomly assigned to one of 3 teaching groups: HPS (n=30), CD-ROM (n=31), or a control group (n=31). Analysis of variance and a Tukey post-hoc test were used to analyze the data. The means on MCWPP instrument were as follows: HPS (pretest: mean=65.13, SD ± 8.9; posttest mean=73.0, SD ± 8.6); CD-ROM (pretest: mean=67.74, SD ± 11.18, posttest mean=65.67, SD ± 10.82); control (pretest: mean=68.51 SD ± 8.5; posttest mean=62.6, SD ± 8.6). There were no significant differences between the groups on the pretest (P=.363), but there were significant differences on the posttest (P=.001). Post-hoc analyses indicated the HPS group performed better than the CD-ROM group (P=.017) and the control group (P=.000). There was no significant difference between the CD-ROM and control groups (P=.485). Based on the results of this study, the HPS is more effective than the CD-ROM in teaching nurses about the care of patients exposed to chemical agents.

The realistic and practical environment that simulation provides is an extremely useful part of the teaching process. Simulation is widely used in health and nursing education today. This study aims to evaluate the effect of simulation-based teaching on the acquisition and retention of arrhythmia-related knowledge among nursing students. A randomized controlled design involving a pretest-posttest was used. Nursing students were allocated randomly either to the experimental group (n = 47), who attended simulation scenarios on cardiac arrhythmia, or to the control group (n = 44) who received a traditional lecture on the same topic. A paired t test showed that the mean knowledge score at the posttest was significantly higher than at the pretest for both groups. However, participants in the experimental group demonstrated significantly increased knowledge of cardiac arrhythmia in the first and the second posttest compared with those in the control group. Thus, simulation is superior and significantly improves students' arrhythmia knowledge. © The Author(s) 2014.

Singleton, J C; Achterberg, C L; Shannon, B M

1992-01-01

Sixty healthy children, 4 to 7 years of age, were interviewed to evaluate their health perceptions in general and to determine the degree to which they included food and eating behavior in their perceptions. Individual interviews with children incorporated both closed-ended and open-ended questions. Concept maps were used to analyze interview transcripts. The pretest/posttest experimental design randomly assigned children to experimental and control groups. Children in the experimental group completed a 4-week, home-based, nutrition education program to determine the feasibility of changing children's health perceptions with an educational intervention. Pretest and posttest health perception scores were compared by analysis of covariance. Results indicated that children perceived nutrition as a meaningful concept in relation to their health perceptions at pretest, but that after program participation, children significantly increased their perception that health and nutrition were related concepts. Our findings indicate that young children are cognitively ready to learn more about food, nutrition, and health than previously thought, but closed-ended questions may not be sensitive enough to evaluate their learning at this age.

Padmavathi, P

2014-01-01

Premenstrual syndrome is the most common of gynaecologic complaints. It affects half of all female adolescents today and represents the leading cause of college/school absenteeism among that population. It was sought to assess the effectiveness of acupressure Vs reflexology on premenstrual syndrome among adolescents. Two-group pre-test and post-test true experimental design was adopted for the study. Forty adolescent girls from Government Girls Secondary School, Erode with pre- menstrual syndrome fulfilling the inclusion criteria were selected by simple random sampling. A pre-test was conducted by using premenstrual symptoms assessment scale. Immediately after pre-test acupressure Vs reflexology was given once a week for 6 weeks and again post-test was conducted to assess the effectiveness of treatment. Collected data was analysed by using descriptive and inferential statistics. In post-test, the mean score of the experimental group I sample was 97.3 (SD = 2.5) and the group II mean score was 70:8 (SD = 10.71) with paired 't' value of 19.2 and 31.9. This showed that the reflexology was more effective than acupressure in enhancing the practice of the sample regarding pre-menstrual syndrome. Statistically no significant association was found between the post-test scores of the sample with their demographic variables. The findings imply the need for educating adolescent girls on effective management of pre-menstrual syndrome.

2016-11-01

Less than 20% of the 996 NICUs in the United States routinely practice kangaroo care, due in part to the inadequate knowledge and skills confidence of nurses. Continuing education improves knowledge and skills acquisition, but the effects of a kangaroo care certification course on nurses' knowledge and skills confidence are unknown. A pretest-posttest quasi-experiment was conducted. The Kangaroo Care Knowledge and Skills Confidence Tool was administered to 68 RNs at a 2.5-day course about kangaroo care evidence and skills. Measures of central tendency, dispersion, and paired t tests were conducted on 57 questionnaires. The nurses' characteristics were varied. The mean posttest Knowledge score (M = 88.54, SD = 6.13) was significantly higher than the pretest score (M = 78.7, SD = 8.30), t [54] = -9.1, p = .000), as was the posttest Skills Confidence score (pretest M = 32.06, SD = 3.49; posttest M = 26.80, SD = 5.22), t [53] = -8.459, p = .000). The nurses' knowledge and skills confidence of kangaroo care improved following continuing education, suggesting a need for continuing education in this area. J Contin Educ Nurs. 2016;47(11):518-524.

Pozarski Connolly, Catherine J.

This research evaluates the effectiveness of Project ReCharge, an energy efficiency, STEM curriculum designed for middle and high school students. The project includes a five-unit curriculum, and monthly professional development spanning a year. The project was implemented in ten schools over three years. Four areas were explored in the study including (1) changes to student content knowledge, (2) changes to student attitudes towards STEM subjects and careers, (3) changes to teacher self-efficacy and beliefs, and (4) changes to teacher content knowledge. A content test for teachers and students, the STEM Semantics Survey, and STEBI-A were used to collect data on 4123 students and 47 teachers. Data were collected in a quasi-experimental design utilizing parametric and nonparametric techniques. Analyses suggest student content knowledge increased significantly from pretest to posttest for all years (Pretest: M = 11.38, SD = 4.97, Posttest: M = 16.67, SD = 5.83, t = 45.05, p < 0.001, d = 0.98). Increases to student attitudes in STEM varied by year and grade, but overall increases were found in science (N = 2362, z = -2.618, p = 0.030, eta 2 = 0.002), and math attitudes (N = 2348, z = -2.280, p = 0.023, eta2 = 0.002). High school students tended to show more increased attitudes in more subject areas than middle school students. No changes to teacher self-efficacy and beliefs were found, and increases to teacher content knowledge only occurred in the third year (N = 22, x2 = 5.158; p = 0.076, eta2 = 0.319).

Exposure to solar ultraviolet radiation during recreation is a risk factor for skin cancer. A trial evaluated an intervention to promote advanced sun protection (sunscreen pre-application/reapplication; protective hats and clothing; use of shade) during vacations. Adult visitors to hotels/resorts with outdoor recreation (i.e., vacationers) participated in a group-randomized pretest-posttest controlled quasi-experimental design in 2012-14. Hotels/resorts were pair-matched and randomly assigned to the intervention or untreated control group. Sun. protection (e.g., clothing, hats, shade and sunscreen) was measured in cross-sectional samples by observation and a face-to-face intercept survey during two-day visits. Initially, 41 hotel/resorts (11%) participated but 4 dropped out before posttest. Hotel/resorts were diverse (employees=30 to 900; latitude=24° 78' N to 50° 52' N; elevation=2ft. to 9726ft. above sea level), and had a variety of outdoor venues (beaches/pools, court/lawn games, golf courses, common areas, and chairlifts). At pretest, 4347 vacationers were observed and 3531 surveyed. More females were surveyed (61%) than observed (50%). Vacationers were mostly 35-60years old, highly educated (college education=68%) and non-Hispanic white (93%), with high-risk skin types (22%). Vacationers reported covering 60% of their skin with clothing. Also, 40% of vacationers used shade; 60% applied sunscreen; and 42% had been sunburned. The trial faced challenges recruiting resorts but result showed that the large, multi-state sample of vacationers were at high risk for solar UV exposure. Copyright © 2015 Elsevier Inc.

This study was designed to examine the effects of a bereavement intervention program on levels of depression and life satisfaction in middle aged widows in Korea. A quasi-experimental design with non-equivalent control-group pretest-posttest was used. The subjects (control group, n = 10; intervention group, n = 17) were bereaved less than 6 months in G City and J Province, Korea. The bereavement intervention program consisted of Dan-jeon breathing, self-help group activities and a health examination. The experimental group attended 10 sessions of a bereavement intervention program. The control group had a health examination without the intervention program. For both groups, the level of depression and life satisfaction levels were measured before and after the experiment. The decrement of depression level in the experimental group was significantly greater than in the control group (p<.001). The increment in life satisfaction in the experimental group was significantly greater than in the control group (p<.001). The results suggested that the bereavement intervention program was effective in decreasing level of depression and in increasing the life satisfaction of widows. Accordingly, a bereavement intervention program can be applied as an intervention to help widows.

Background On July 24, 2008, New York State (NYS) became the first state to require all state-funded or state-certified substance use disorder (SUD) treatment organizations to be 100% tobacco-free and offer tobacco cessation (TC) treatment. Methods The current study used a quasi-experimental, non-equivalent control group design with a pretest and posttest to examine the effect of the NYS tobacco-free regulation on three clinical practice behaviors (use of TC-related intake procedures, use of guideline recommended counseling for TC, and pharmacotherapy availability) in a diverse sample of SUD treatment programs. Repeated cross-sectional data were collected from NYS counselors (experimental group) and non-NYS counselors (control group) approximately 4 months pre-regulation (N = 282 and 659, respectively) and 10-12 months post-regulation (N = 364 and 733, respectively). Results Using mixed-effects models, results at pre-regulation indicate no group differences in the three clinical practice behaviors. However, significant post-regulation effects were found such that the experimental group reports greater use of TC-related intake procedures, guideline recommended counseling, and availability of pharmacotherapy than the control group. Additionally, the experimental but not the control group shows increases in all three clinical practice behaviors from pre-regulation to post-regulation. Conclusions We conclude that the NYS tobacco-free regulation had a significant and positive effect on promoting patient TC efforts among counselors. PMID:23428317

There is a paucity of research on the effects of pretest measurement with prostate cancer screening. What effect does a pretest measurement have on posttest outcomes? This research reports knowledge of prostate cancer screening among men randomized to an Enhanced decision aid versus an Usual Care decision aid. Using a Solomon Four research design, there were a total of 198 men in 4 groups. Most of the sample was African American (78%), with a mean age of 52 years. The greatest posttest knowledge occurred with the Enhanced decision aid in contrast to the Usual Care. The Enhanced/Usual Care groups that had both a pretest and posttest and had received a previous digital rectal examination had the highest means (P = .015), with means of 9.1 and 7.0, respectively. Among men who had a previous digital rectal examination, the greatest increase in score occurred among men randomized to the Enhanced decision aid in contrast to the Usual Care decision aid, 2.9 versus 0.4 (P = .008). The outcome varied based on the status of (1) random group assignment of the Solomon Four design and (2) status of previous digital rectal examination. Implications for nurses include consideration 1 of a pretest to increase posttest knowledge scores.

2017-10-01

This study, grounded in Self-Determination Theory (Deci and Ryan, 1985, 2002) was aimed to determine the influence of a cognitive-motivational intervention program, to improve the basic psychological need satisfaction of autonomy and competence, autonomous motivation, procedural knowledge, perceived performance and sport commitment, in youth volleyball players. Participants included 34 Under-19 female volleyball players. A quasi-experimental design was carried out with an experimental group (n = 16; M = 17.45; SD = .45) and a control group (n = 18; M = 16.64; SD = .70). The experimental group followed a multidimensional intervention program comprised of 24 sessions held over three months (two training sessions per week). It was based on two strategies: giving athletes the possibility of choice in specific training tasks (proposing training situations with several action alternatives) and questioning (cognitively involving players through tactical questions). A repeated-measures MANOVA 2 (group: experimental and control) x 2 (time: pre-test and post-test) was used to analyse the effect of Group x Time interaction. The results of the inter-group analysis showed significant differences in the post-test measurement between the experimental group and the control group (in favour of the experimental group) in the variables: basic psychological need satisfaction of autonomy and competence, autonomous motivation, procedural knowledge, perceived performance and sport commitment. Given the relevance of the cognitive-motivational processes, not only for performance but also for sport commitment, this intervention has important implications for sport coaching.

1979-03-01

A film emphasizing the importance of tachypnea as an early manifestation of congenital heart disease was shown to physicians and nurses at 27 hospitals as part of their regular continuing medical education activities. To evaluate the effects of the program, investigators developed a pretest-posttest design which included a nonequivalent control group. Pretest and posttest data were obtained through chart audit of referrals from subjects in experimental and control groups. Dependent variables used to test the hypothesis included the age at which infants were referred and the age at which tachypnea was noted. Analysis of the data yielded significant gain scores for the experimental group, while changes in the control group were not significant. The findings indicate that a need-oriented educational program can have a measurable impact on improving the quality of patient care.

Literature provides adequate evidence of a poor perception of nursing within the profession, resulting in high rates of attrition of student nurses and newly qualified nurses. The nursing profession, in particular nurse educators, has an ethical and professional responsibility to find innovative strategies to promote the positive image of nursing amongst student nurses. The purpose of the study was to explore the potential of appreciative inquiry (AI) as an intervention teaching strategy to transform student nurses' image of nursing. A quantitative, quasi-experimental, explorative-descriptive design comprising the pretest, appreciative inquiry as intervention, and the post-test was used. Convenience sampling was used to select third and fourth year college and university student nurses in the Gauteng province of South Africa for the pre- and the post-test respectively. Data were collected by means of a questionnaire and analysed by SPSS version 20.0. The pretest results revealed a mix of positive and negative perceptions of the image of nursing amongst student nurses. The negative perceptions of the image of nursing that needed intervention included the working conditions of nurses, and the perception of nursing as a profession that was not respected and appreciated. The post-test results showed a significant and positive change in the student nurses' perception of the image of nursing as a respected and appreciated profession. Although AI resulted in a negative to positive change in some aspects of student nurses' image of nursing, the negative perceptions of the working conditions of nurses remained and became more negative. The positive image of gender in nursing was enhanced following the implementation of AI. Appreciative inquiry demonstrated potential as a teaching strategy to produce a positive nursing image change and positive orientation towards nursing amongst student nurses.

Our study was conducted in three steps (pre-test, education intervention, post-test). Data were collected from November 2013 to February 2014. The educational intervention was performed using online access to virtual learning object about acute pain assessment, which students accessed on their mobile devices. A significant difference was seen in student learning (p<0.001) in the post-test compared with the pre-test results. The students understood the importance of the topic, and were satisfied and motivated by the technology and method applied. The use of persuasive technology such as small mobile devices as mediators of online educational interventions broadens learning spaces in an innovative, flexible, motivational, and promising manner.

Nurses are usually the first to identify the need for and initiate cardiopulmonary resuscitation (CPR) on patients with cardiopulmonary arrest in the hospital setting. Cardiopulmonary resuscitation has been shown to reduce in-hospital deaths when received from adequately trained health care professionals. We aimed to investigate nurses' retention of CPR knowledge and skills at district hospitals in Botswana. A quantitative, quasi-experimental study was conducted at three hospitals in Botswana. A pre-test, intervention, post-test, and a re-test after 6 months were utilised to determine the retention of CPR knowledge and skills. Non-probability, convenience sampling technique was used to select 154 nurses.The sequences of the test were consistent with the American Heart Association's 2010 basic life support (BLS) guidelines for health care providers. Data were analysed to compare performance over time. This study showed markedly deficient CPR knowledge and skills among registered nurses in the three district hospitals. The pre-test knowledge average score (48%) indicated that the nurses did not know the majority of the BLS steps. Only 85 nurses participated in the re-evaluation test at 6 months. While a 26.4% increase was observed in the immediate post-test score compared with the pre-test, the performance of the available participants dropped by 14.5% in the re-test 6 months after the post-test. Poor CPR knowledge and skills among registered nurses may impede the survival and management of cardiac arrest victims. Employers and nursing professional bodies in Botswana should encourage and monitor regular CPR refresher courses.

Traditional lecture-based learning (LBL) can increase cancer awareness in undergraduates. However, because of the rapidly changing knowledge base in medicine, undergraduates must develop skills required for lifelong self-directed learning (SDL). Problem-based learning (PBL) has been suggested as an SDL approach. This study used a nonequivalent control group with a pretest-posttest design for comparing PBL and LBL for their effectiveness in increasing cancer awareness and SDL among nonmedicine or nonnursing major undergraduates in a health-related general education course. Experimental groups 1 and 2 were instructed using PBL while the control group was instructed using LBL. Cancer educational programs were offered to experimental group 1 and the control group but not to experimental group 2. Among the 325 undergraduates who completed a questionnaire regarding cancer awareness and SDL in the pretest, 223 completed the 12-week follow-up survey of the posttest. Cancer awareness significantly improved between the pretest and posttest in the control group (P < 0.001). No significant difference in cancer awareness improvement was observed between experimental group 1 and the control group (P = 0.934). Cancer awareness improvement in experimental group 2 was significantly less than in the control group (P = 0.010). No statistically significant change in SDL was observed in the control group during the study (P = 0.897). However, the SDL of experimental groups 1 and 2 improved more significantly than that of the control group (P = 0.049 and 0.023, respectively). Therefore, PBL is an effective method of increasing cancer awareness and SDL in undergraduates.

2014-01-01

An experimental study was conducted using a 2-group randomized control pretest/ posttest design to determine if knowledge about Pap testing could be increased through use of a nurse-designed mobile smartphone app developed to educate individuals about the Pap test. A 14-item pretest survey of knowledge about Pap tests was distributed to women attending a university in New England. Participants in the intervention group were provided with an Android device on which a digital health education application on Pap testing had been downloaded. The control group was given a standard pamphlet on Pap testing., Paired t test results demonstrated that knowledge scores on the posttest increased significantly in both groups, but were significantly higher in the intervention group. User satisfaction with the app was high. The results of this study may enhance nursing care by informing nurses about a unique way of learning about Pap testing to recommend to patients.

One of the most serious problems in the Spanish education system is the high percentage of school failure in Compulsory Secondary Education. The aim of this study is to analyze the influence of a socio-educational program based on cooperative learning and family involvement on a series of variables related to academic performance, paying particular attention to the differences between retained and non-retained students. A two-group quasi-experimental design incorporating pre-testing and post-testing was used. The study involved 146 students in the experimental group and 123 in the control group, 8 teachers, and 89 parents or other family members. The program was observed to have a positive effect on self-image, study habits, satisfaction with the subject, maternal support and control, and opinions about the school. In addition, the results for non-retained students are better. Cooperative work and family involvement in education affect the variables which research links to improving school performance.

This chapter reviews 73 published and unpublished research reports of interventions for family members caring for an elder with dementia by nurse researchers and researchers from other disciplines. Reports were identified through searches of MEDLINE, CINAHL, Social Science Index, PsycINFO, ERIC, Social Work Abstracts, American Association of Retired Persons database, CRISP index of the National Institutes of Health, Cochrane Center database, and Dissertation Abstracts using the following search terms: caregiver, caregiving, dementia, Alzheimer's, intervention study, evaluation study, experimental, and quasi-experimental design. Additional keywords were used to narrow or expand the search as necessary. All nursing research was included in the review and nonnursing research was included if published between 1991 and 2001. Studies were included if they used a design that included a treatment and control group or a one-group, pretest-posttest design (ex post facto designs were included if they used a comparison group). Key findings show that approximately 32% of the study outcomes (e.g., burden, depression, knowledge) were changed after intervention in the desired direction. In addition, several problematic issues were identified including small, diverse samples; lack of intervention specificity; diversity in the length, duration, and intensity of the intervention strategies; and problematic outcome measures.

Postpartum depression is one of the prevalent disorders among new mothers. The present research aimed to examine the effectiveness of mindfulness training on reducing the symptoms of postpartum depression. The present quasi-experimental research was conducted on 410 new mothers in Shahid Chamran Hospital, Tehran in 2014. Using the Beck Depression Inventory (BDI), Structured Clinical Interview and Psychological Clinical Diagnosis, 67 mothers were selected and then randomly divided into experimental and control groups, each of which with 32 applicants. Afterwards, the experimental group received mindfulness training for 8 sessions, each lasting for two hours while the control group received no training. The data were analyzed through descriptive statistics and Analysis of Covariance (ANCOVA) in SPSS, version 20. Results showed that based on Beck Inventory, the scores for the experimental group in post-test were significant (p<0.001), compared to those for the control group. Also, it was revealed that pre- and posttest mean scores for postpartum depression in the control group were 25.81 and 25.12 respectively while the scores for the experimental group were 24.75 and 18.5 respectively. Since the posttest mean score in the experimental group was lower than that in the pretest, it can be said that the treatment, i.e., mindfulness training, was effective in reducing depression symptoms in mothers. Findings proved that mindfulness training was effective in reducing the symptoms of postpartum depression in new mothers.

This study aims to find the effectiveness of math education using Google Apps for Education (GAFE) as learning management system to improve mathematical communication skill primary school preservice teacher. This research used quasi-experimental approach, utilizing the control group pre-test - post-test design of two group of primary school preservice teachers at UPI Kampus Purwakarta. The result of this study showed that mathematical communication skill of primary school preservice teacher in the experiment group is better than the control group. This is because the primary school preservice teacher in the experiment group used GAFE as a tool to communicate their idea. The students can communicate their idea because they have read the learning material on the learning management system using GAFE. All in all, it can be concluded that the communication tool is very important, beside the learning material, and also the options to choose the learning model to achieve the better result.

In this technology era, information literacy is a global imperative. This is true for nursing students as well because they will have to help patients through operating computerized equipment. The key foundation of learning is concentration. The primary objectiveof this research was to explore the effect of clickers on nursing college students' concentration. The research involved 51 student volunteers and was quasi-experimental, with both a pretest and a posttest design. Student concentration was measured by using Student Concentration Scale in a Classroom-Learning Environment. The results showed that students' learning concentration improved, an outcome that could support integrating clickers into classroom teaching activities, and students' concentration level was better after clickers were used in the teaching process as a whole. Items under the "Concentration Capacity and Concentration Consciousness" category reached a significant level. Based on the analysis of the results, suggestions have been made for teaching and future research.

Case-based learning (CBL) is a teaching strategy which promotes clinical problem-solving ability. This research was performed to investigate the effects of CBL on problem-solving ability of graduate nurses. This research was a quasi-experimental design using pre-test, intervention, and post-test with a non-synchronized, non-equivalent control group. The study population was composed of 190 new graduate nurses from university hospital A in Korea. Results of the research indicate that there was a statistically significant difference in objective problem-solving ability scores of CBL group demonstrating higher scores. Subjective problem-solving ability was also significantly higher in CBL group than in the lecture-based group. These results may suggest that CBL is a beneficial and effective instructional method of training graduate nurses to improve their clinical problem-solving ability. Copyright © 2013 Elsevier Ltd.

Positive interventions have shown promise for fostering hedonic (happiness) and eudaimonic (flourishing) well-being. However, few studies have focused on positive interventions that target hope as a means of increasing well-being, and none have examined the use of smartphone app-based systems for delivering interventions in the moments and contexts of daily life-an approach called ecological momentary intervention (EMI). We conducted a quasi-experimental pilot study using a pretest and posttest design to examine the feasibility and potential impact of a mobile app-based hope EMI. Participants appeared to engage with the intervention and found the experience to be user-friendly, helpful, and enjoyable. Relative to the control group, those receiving the intervention demonstrated significantly greater increases in hope; however, there were no between-group differences in hedonic and eudaimonic well-being. The authors recommend future research to examine the potential of EMI mobile apps to cultivate hope and promote flourishing.

Breast cancer patients frequently experience psychological distress during the chemotherapy period. This study aimed to evaluate the effect of relaxation with guided imagery on patients with breast cancer. A two-group, pretest-posttest, quasi-experimental design with a randomized controlled trial was conducted. Sixty-five breast cancer patients from one medical center in Taiwan were enrolled in the study. These patients were randomly assigned to the experimental group (n = 32) or to the control group (n = 33). Both groups received chemotherapy self-care education, but the experimental group also received relaxation with guided imagery training. The training on relaxation with guided imagery was conducted before chemotherapy, and the patients were supplied with a compact disc detailing the performance of relaxation with guided imagery for 20 minutes daily at home for 7 days after chemotherapy. The experimental group showed significant decreases in insomnia (-0.34 ± 0.83, P < 0.05), pain (-0.28 ± 0.58, P < 0.05), anxiety (-3.56 ± 2.94, P < 0.00), and depression (-2.38 ± 2.70, P < 0.00) between the pretest and the posttest. Comparing the two groups, statistically significant differences were found in the overall symptom distress (B = 0.11, P < 0.05), insomnia (B = 0.50, P <0.05), depression (B = 0.38, P < 0.05), and numbness in physical symptoms (B = 0.38, P < 0.05), as well as in anxiety (B = 3.08, P < 0.00) and depression (B = 1.86, P < 0.00) in psychological distress. One week of relaxation with guided imagery can significantly improve the overall symptoms of distress, insomnia, depression, physical symptoms, and anxiety, and can decrease psychological distress. Relaxation with guided imagery had a positive effect on mediating anxiety and depression in breast cancer patients.

Surgenor, Paul Wg; Freeman, Joan; O'Connor, Cindy

2015-01-01

While most crisis intervention models adhere to a generalised theoretical framework, the lack of clarity around how these should be enacted has resulted in a proliferation of models, most of which have little to no empirical support. The primary aim of this research was to propose a suicide intervention model that would resolve the client's suicidal crisis by decreasing their suicidal ideation and improve their outlook through enhancing a range of protective factors. The secondary aim was to assess the impact of this model on negative and positive outlook. A quasi-experimental, pre-test post-test repeated measures design was employed. A questionnaire assessing self-esteem, depression, and positive and negative suicidal ideation was administered to the same participants pre- and post- therapy facilitating paired responses. Multiple analysis of variance and paired-samples t-tests were conducted to establish whether therapy using the PH-SIM had a significant effect on the clients' negative and positive outlook. Analyses revealed a statistically significant effect of therapy for depression, negative suicidal ideation, self-esteem, and positive suicidal ideation. Negative outlook was significantly lower after therapy and positive outlook significantly higher. The decreased negative outlook and increased positive outlook following therapy provide some support for the proposed model in fulfilling its role, though additional research is required to establish the precise role of the intervention model in achieving this.

The purpose of this study was: (a) To evaluate and to compare the impact of three music programs (choir, music appreciation and preventive music therapy sessions) on the quality of life of healthy older adults, and (b) to identify the motivations and the difficulties that seniors encounter when participating in activities of this type, in order to come up with recommendations and strategies for the design of appropriate programs for older adults. A pre-posttest quasi-experimental design without equivalent control group was used in this project. The sample included 83 persons over 65 years of age. The data collection was carried out through an ad hoc questionnaire that included the four aspects of the construct of quality of life (physical health, subjective health, psychological well-being and interpersonal relations), a questionnaire on motivation and another on satisfaction about the program. This questionnaire on quality of life was administered twice: at the beginning of the programs (pretest) and at the end (posttest). The results of this study indicate that the participants perceived improvements in some aspects of their quality of life. In addition, the main reasons which motivate participation in these musical activities are to broaden the social network and to acquire new knowledge. The results are discussed in the light of the challenges of active and satisfactory aging.

The main goal of this study was to determine the short-term and follow-up effectiveness of despair and empowerment workshops. Such workshops are designed to encourage the expression of feelings related to the nuclear threat (as well as other planetary issues), and to generate a greater sense of personal powerfulness. Results were as follows. At pretest, experimental workshop participants reported a significantly lower level of nuclear-related denial, and were found to be significantly more politically active than control participants. When controlling for these pretest differences, no significant differences were found across conditions at post-test or follow-up. In addition, experimental workshop participantsmore » were found to report significantly more powerfulness than nonworkshop control participants at post-test, but no significant post-test differences were found between the two workshop conditions. Open ended evaluation questions, asked only of experimental workshop participants, suggested that most participants responded favorably to the despair and empowerment workshops - particularly in reference to being given the opportunity to express their nuclear-related concerns and to feel supported by others. In summary, this study provides some evidence, despite mixed results, of the effectiveness of despair and empowerment workshops.« less

This article describes a field experiment with a pretest-posttest control group design which investigated the potential of reading picture books to children for supporting their mathematical understanding. The study involved 384 children from 18 kindergarten classes in 18 schools in the Netherlands. During three months, the children in the nine experimental classes were read picture books. Data analysis revealed that, when controlled for relevant covariates, the picture book reading programme had a positive effect ( d = .13) on kindergartners' mathematics performance as measured by a project test containing items on number, measurement and geometry. Compared to the increase from pretest to posttest in the control group, the increase in the experimental group was 22% larger. No significant differential intervention effects were found between subgroups based on kindergarten year, age, home language, socio-economic status and mathematics and language ability, but a significant intervention effect was found for girls and not for boys.
Development and effectiveness of an educational card game as supplementary material in understanding selected topics in biology.

The complex concepts and vocabulary of biology classes discourage many students. In this study, a pretest-posttest model was used to test the effectiveness of an educational card game in reinforcing biological concepts in comparison with traditional teaching methods. The subjects of this study were two biology classes at Bulacan State University-Sarmiento Campus. Both classes received conventional instruction; however, the experimental group's instruction was supplemented with the card game, while the control group's instruction was reinforced with traditional exercises and assignments. The score increases from pretest to posttest showed that both methods effectively reinforced biological concepts, but a t test showed that the card game is more effective than traditional teaching methods. Additionally, students from the experimental group evaluated the card game using five criteria: goals, design, organization, playability, and usefulness. The students rated the material very satisfactory.
Do humorous preoperative teaching strategies work?

PubMed

Schrecengost, A

2001-11-01

Incorporating humor into preoperative teaching may improve patients' ability to recall pertinent instruction. This article describes a study in which an experimental, two-group, pretest/posttest design was used to determine whether there was a significant difference in the amount of knowledge patients recalled after receiving a teaching booklet either with (i.e., experimental) or without (i.e., control) humor. The sample included 50 patients undergoing open-heart surgery. Results indicate that there was no significant difference (F1, 48 = .07, P > .05) between the groups in the amount of knowledge gained related to postoperative pulmonary exercises. Both groups, however, had a statistically significant increase in the amount of knowledge gained from pretest to posttest (F1, 48 = 39.16, P < .05). Before humorous teaching strategies can be recommended for use in preoperative teaching, further research about the relationship between preoperative instruction, humor, and knowledge retention is necessary.

This study was conducted at Karikalampakkam village of Puducherry. Karikalampakkam is a Community Health Center with seven subcenters under it. The research design was one of the Quasi Experimental Design pre and post test with one group. All the health personnels like ANM, PHN, Health educators were considered as subjects for the study. The sample size was 40 and selected by purposive sampling technique. Pretest was conducted before the CME programme with the structured interview schedule. Post test was conducted after completion of the programme with the help of same tool. The pretest mean knowledge score among the health personnels was 3.15 ± 0.89 with the mean percentage 7.8 % whereas the posttest mean knowledge score was 4.47 ± 1.58 with mean percentage 11.17 %. The Z value was -2.555 and the p value was 0.011 (p < 0.05) which was significant at 0.05 level. Though the health personnels are already trained, during pretest their knowledge level was found to be poor and after training, the results show that their knowledge improved. Thus, there is a necessity to conduct inservice training programmes to update knowledge and skill of health personnels.

Mehta, Purvi; Sharma, Manoj

Yoga is often viewed as a form of alternative and complementary medicine, as it strives to achieve equilibrium between the body and mind that aids healing. Studies have shown the beneficial role of yoga in anxiety reduction. The purpose of this study was to design and evaluate a 10-week social cognitive theory based yoga intervention to reduce anxiety. The yoga intervention utilized the constructs of behavioral capability, expectations, self-efficacy for yoga from social cognitive theory, and included asanas (postures), pranayama (breathing techniques), shava asana (relaxation), and dhyana (meditation). A one-between and one-within group, quasi-experimental design was utilized for evaluation. Scales measuring expectations from yoga, self-efficacy for yoga, and Speilberger's State Trait Anxiety Inventory, were administered before and after the intervention. Repeated measures analyses of variance (ANOVA) were performed to compare pre-test and post-test scores in the two groups. Yoga as an approach shows promising results for anxiety reduction.

The purpose of this study was to explore the effects of case-based learning on communication skills, problem-solving ability, and learning motivation in sophomore nursing students. In this prospective, quasi-experimental study, we compared the pretest and post-test scores of an experimental group and a nonequivalent, nonsynchronized control group. Both groups were selected using convenience sampling, and consisted of students enrolled in a health communication course in the fall semesters of 2011 (control group) and 2012 (experimental group) at a nursing college in Suwon, South Korea. The two courses covered the same material, but in 2011 the course was lecture-based, while in 2012, lectures were replaced by case-based learning comprising five authentic cases of patient-nurse communication. At post-test, the case-based learning group showed significantly greater communication skills, problem-solving ability, and learning motivation than the lecture-based learning group. This finding suggests that case-based learning is an effective learning and teaching method. © 2014 Wiley Publishing Asia Pty Ltd.

One of the important tasks of nurses in intensive care unit is interpretation of ECG. The use of training simulator is a new paradigm in the age of computers. This study was performed to evaluate the impact of cardiac arrhythmias simulator software on nurses' learning in the subspecialty Vali-Asr Hospital in 2016. This study was conducted by quasi-experimental randomized Salomon four group design with the participation of 120 nurses in subspecialty Vali-Asr Hospital in Tehran, Iran in 2016 that were selected purposefully and allocated in 4 groups. By this design other confounding factors such as the prior information, maturation and the role of sex and age were controlled by Solomon 4 design. The valid and reliable multiple choice test tools were used to gather information; the validity of the test was approved by experts and its reliability was obtained by Cronbach's alpha coefficient 0.89. At first, the knowledge and skills of the participants were assessed by a pre-test; following the educational intervention with cardiac arrhythmias simulator software during 14 days in ICUs, the mentioned factors were measured for the two groups again by a post-test in the four groups. Data were analyzed using the two way ANOVA. The significance level was considered as p<0.05. Based on randomized four-group Solomon designs and our test results, using cardiac arrhythmias simulator software as an intervention was effective in the nurses' learning since a significant difference was found between pre-test and post-test in the first group (p<0.05). Also, other comparisons by ANOVA test showed that there was no interaction between pre-test and intervention in all of the three knowledge areas of cardiac arrhythmias, their treatments and their diagnosis (P>0.05). The use of software-based simulator for cardiac arrhythmias was effective in nurses' learning in light of its attractive components and interactive method. This intervention increased the knowledge of the nurses in cognitive domain of cardiac arrhythmias in addition to their diagnosis and treatment. Also, the package can be used for training in other areas such as continuing medical education.

We examined the effects of high- versus low-anxiety conditions during video-based training of anticipation judgments using international-level badminton players facing serves and the transfer to high-anxiety and field-based conditions. Players were assigned to a high-anxiety training (HA), low-anxiety training (LA) or control group (CON) in a pretraining-posttest design. In the pre- and posttest, players anticipated serves from video and on court under high- and low-anxiety conditions. In the video-based high-anxiety pretest, anticipation response accuracy was lower and final fixations shorter when compared with the low-anxiety pretest. In the low-anxiety posttest, HA and LA demonstrated greater accuracy of judgments and longer final fixations compared with pretest and CON. In the high-anxiety posttest, HA maintained accuracy when compared with the low-anxiety posttest, whereas LA had lower accuracy. In the on-court posttest, the training groups demonstrated greater accuracy of judgments compared with the pretest and CON.

The current investigation involved an attempt to develop a clinical procedure to decrease anxiety and increase responsiveness (assertion) of psychiatric inpatients of both sexes in mixed diagnostic categories and to evaluate the effectiveness of the procedure. Using a Solomon Four-Group Design, patients, matched on age, sex, and diagnosis, were assigned to one of the following conditions: (1) pretest, treatment, posttest; (2) pretest, no treatment, posttest; (3) treatment, posttest; or (4) no treatment, posttest. The Gambrill-Richey Assertive Inventory was used to assess patient Degree of Discomfort and Response Probability with and without assertion training therapy. Results indicated that (1) patients receiving assertion training therapy were less anxious and more responsive after treatment than before, (2) patients receiving assertion training therapy were less anxious and more responsive than were matched control subjects, (3) control subjects who received no assertion training therapy and who were pretested showed moderate significant gains on the posttest measure, (4) patients reported a greater reduction of anxiety than they did an increase in responsiveness, and (5) pretesting did not significantly influence posttest scores.

In order to test its short- and middle-term impact as well as differential gender effects the universal school-based "Verhaltenstraining für Schulanfänger", a German prevention program on antisocial behavior for elementary school students, was conducted and evaluated in Luxembourg. In a quasi-experimental setting, nine first grade classes (n=88) were assigned to intervention and control groups. Three waves of data (pretest, posttest and 12-months-follow up) including teacher and student assessments were analysed. As a result intervention effects in terms of significant reductions in oppositional defiant and aggressive behavior as well as an increase in social and emotional competencies according to teachers' assessments at 12-months-follow-up could be observed. Student interviews showed positive short-term effects in terms of increased emotional knowledge and social problem solving competencies at posttest, with girls showing a stronger improvement of their emotional knowledge than boys.

A number of studies have shown that the traditional lecture suffers from limitations in the development of many important competencies such as reasoning ability for nursing professionals. In view of this issue, the authors present a promising alternative to the traditional lecture: the Guided University Debate (GUD). With regard to this aim a teaching-learning sequence of schizophrenia is described based on the GUD. Next, the improvement in the argumentative and declarative knowledge of the students who have participated in the said methodology is demonstrated. Quasi-experimental study with pre-test and post-test design to measure differences in the improvement of declarative and argumentative knowledge. To determine if there is a statistically significant difference in the score obtained in the pre-test and in the post-test score a parametric t-tests was carried. 64 students participated in the study. Implementation of the study took place during the 2015-2016 academic year in the third year of the Nursing undergraduate degree course in the University of the Basque Country (UPV/EHU) as part of the Mental Health class. The results showed a statistically-significant improvement in the students' scores for all learning outcomes analysed: Identifies symptoms of schizophrenia (p≤0.001), identifies the nursing interventions (p≤0.001), provides a rationale for nursing interventions (p≤0.001) and provides evidence of nursing interventions (p≤0.001). That is, the declarative and argumentative capacity of the group improved significantly with the Guided University Debate methodology. Although the teaching design feasibility and outcomes may vary in different contexts, based on this studies' positive outcome, the authors call today's educators to be able to use GUD as a teaching method.

Introduction Exposure to solar ultraviolet radiation during recreation is a risk factor for skin cancer. A trial evaluating an intervention to promote advanced sun protection (sunscreen pre-application/reapplication; protective hats and clothing; use of shade) during vacations. Materials and Methods Adult visitors to hotels/resorts with outdoor recreation (i.e., vacationers) participated in a group-randomized pretest-posttest controlled quasi-experimental design in 2012–14. Hotels/resorts were pair-matched and randomly assigned to the intervention or untreated control group. Sun protection (e.g., clothing, hats, shade and sunscreen) was measured in cross-sectional samples by observation and a face-to-face intercept survey during two-day visits. Results Initially, 41 hotel/resorts (11%) participated but 4 dropped out before posttest. Hotel/resorts were diverse (employees=30 to 900; latitude=24o 78′ N to 50o 52′ N; elevation=2 ft. to 9,726 ft. above sea level), and had a variety of outdoor venues (beaches/pools, court/lawn games, golf courses, common areas, and chairlifts). At pretest, 4,347 vacationers were observed and 3,531 surveyed. More females were surveyed (61%) than observed (50%). Vacationers were mostly 35–60 years old, highly educated (college education = 68%) and non-Hispanic white (93%), with high-risk skin types (22%). Vacationers reported covering 60% of their skin with clothing. Also, 40% of vacationers used shade; 60% applied sunscreen; and 42% had been sunburned. Conclusions The trial faced challenges recruiting resorts but result show that the large, multi-state sample of vacationers were at high risk for solar UV exposure. PMID:26593781

Objective: Taking the appropriate psychological actions to boost the mental health of patients with breast cancer is critical. This research was performed with the aim of examining the effectiveness of cognitive-behavioral group therapy on reducing body image concerns in patients with breast cancer. Methodology: TThe method used was quasi-experimental with a pretest-posttest plan and control group. Therefore, 40 patients with breast cancer who had referred to the oncology and radiotherapy department of Imam Hossein Hospital of Tehran were selected by convenience sampling method and organized into two groups: experimental and control group. Both groups were pretested by using demographic and body image concern questionnaires. Then the experimental group received cognitive-behavioral group therapy training for eight sessions and the control group did not receive any intervention. Afterwards, both groups were post-tested, and the data were analyzed by using SPSS software with descriptive and inferential statistics methods. Findings: The findings showed that the cognitive-behavioral group therapy training significantly contributed to the reduction of body image concern in patients with cancer (p < 0.001). Conclusions: It was concluded from this research that cognitive-behavioral group therapy training is an effective strategy to help patients with breast cancer who suffer from the concern about body image due to its high efficiency, especially when it was held in groups, it had low cost, and it was acceptable by the patients.
ANCOVA Versus CHANGE From Baseline in Nonrandomized Studies: The Difference.

PubMed

van Breukelen, Gerard J P

2013-11-01

The pretest-posttest control group design can be analyzed with the posttest as dependent variable and the pretest as covariate (ANCOVA) or with the difference between posttest and pretest as dependent variable (CHANGE). These 2 methods can give contradictory results if groups differ at pretest, a phenomenon that is known as Lord's paradox. Literature claims that ANCOVA is preferable if treatment assignment is based on randomization or on the pretest and questionable for preexisting groups. Some literature suggests that Lord's paradox has to do with measurement error in the pretest. This article shows two new things: First, the claims are confirmed by proving the mathematical equivalence of ANCOVA to a repeated measures model without group effect at pretest. Second, correction for measurement error in the pretest is shown to lead back to ANCOVA or to CHANGE, depending on the assumed absence or presence of a true group difference at pretest. These two new theoretical results are illustrated with multilevel (mixed) regression and structural equation modeling of data from two studies.

To evaluate students' overall assessment and effectiveness of the web-based blended learning conception "Unified Patient Project" (UPP) for medical students rotating on their otolaryngology internship (ear, nose, and throat [ENT] tertiary). Prospective comparison group design of the quasiexperimental type. Medical education. The experimental group (preintervention test [pretest], intervention, and postintervention test [posttest]) comprised 117 students, and the comparison group (pretest, alternative intervention, and posttest), 119. In the experimental group, lecturing of case studies was replaced by the blended learning concept UPP. A standardized questionnaire evaluated students' overall assessment of teaching otolaryngology. A pretest and posttest using multiple choice questions was administered to clarify whether the UPP has led to a knowledge gain. The comparison group was more satisfied with their teaching; however, this was not statistically significant (P = .26) compared with the UPP. Students with higher preknowledge benefitted from the UPP, while students with lower preknowledge did not (P = .01). On average, posttest results in the experimental group exceeded those of the comparison group by 8.7 percentage points for a 75% preknowledge of the maximum attainable score, while they fell below those of the comparison group by 8.1 percentage points for a 25% preknowledge. Students' satisfaction with the blended learning concept UPP was lower than in the face-to-face teaching, although this was not statistically significant. The new web-based UPP leads to an improved knowledge in clinical otolaryngology for all students. Students with lower preknowledge benefitted more from face-to-face teaching than from the UPP, while students with higher preknowledge benefitted more from the UPP. This implies students with poor preknowledge need special promotion programs.
