    Lab activities are an important element of an undergraduate physics course. In these lab activities, students construct and interpret graphs in order to connect the procedures of the lab with an understanding of the related physics concepts. This study investigated undergraduate students' construction and interpretation of graphs with best-fit lines in the context of two physics lab activities. Students' graphs were evaluated for overall graph quality and for the quality of the best-fit line. The strategies students used and their understanding of the meaning of the graph were accessed through interviews. The results suggest that undergraduate introductory physics students can successfully construct graphs with best-fit lines while not connecting the meaning of the graph to the underlying physics concepts. Furthermore, results indicated that the most challenging aspect of constructing a graph is setting up the scale, and that graphing is situated in specific contexts.

    Karahan, Engin; Roehrig, Gillian

    2015-02-01

    Current science education reforms and policy documents highlight the importance of environmental awareness and perceived need for activism. As "environmental problems are socially constructed in terms of their conceptualized effects on individuals, groups, other living things and systems research based on constructivist principles provides not only a coherent framework in which to theorize about learning, but also a context for understanding socially constructed issues" (Palmer and Suggate in Res Pap Educ 19(2), 2004, p. 208). This research study investigated the impacts of the learning processes structured based on the theories of constructionism and social constructivism on students' environmental awareness and perceived need for activism. Students constructed multimedia artifacts expressing their knowledge, attitudes, awareness, and activism about environmental issues through a constructionist design process. In addition, a social networking site was designed and used to promote social interaction among students. Twenty-two high school environmental science students participated in this study. A convergent mixed methods design was implemented to allow for the triangulation of methods by directly comparing and contrasting quantitative results with qualitative findings for corroboration and validation purposes. Using a mixed method approach, quantitative findings are supported with qualitative data (student video projects, writing prompts, blog entries, video projects of the students, observational field notes, and reflective journals) including spontaneous responses in both synchronous and asynchronous conversations on the social network to provide a better understanding of the change in students' environmental awareness and perceived need for activism. The findings of the study indicated that students' environmental awareness and perceived need for activism were improved at different scales (personal, community, global) throughout the constructionist and social

  7. Socially situated activities and identities: Second-grade dual language students and the social construction of science

    NASA Astrophysics Data System (ADS)

    Bryce, Nadine

    Latina and Latino American students are among the lowest achievers in science, when compared to European and Asian American students, and are highly underrepresented in science careers. Studies suggested that a part of this problem is students' lack of access to science, due to their status as English language learners and their perceived status as deficient students. This study investigated the social construction of science in a second grade dual language urban classroom that offered bilingual students access to science, while positioning them as competent, capable learners. What participants valued in science was interpreted from their stated beliefs and attitudes, as well as their patterned ways of reading, writing, and talking. A bilingual European American teacher and three Latina and Latino focal students were observed over the course of 10 weeks, as they enacted a science unit, in English, on habitats. Science lessons were videotaped, documented with field notes, and transcribed. Interviews with the teacher and students were audiotaped and transcribed, and relevant curriculum documents, and teacher- and student-generated documents, copied. Gee's (1999) d/Discourse analysis system was applied to the transcripts of science lessons and interviews as a way to understand how participants used language to construct situated activities and identities in science. Curriculum documents were analyzed to understand the positioning of the teacher and students by identifying the situated activities and roles recommended. Students' nonfiction writing and published nonfiction texts were analyzed for linguistic structures, semantic relationships and conventions of science writing. Results indicated that the teacher drew on traditional and progressive pedagogical practices that shaped her and her students' science activities and situated identities. The teacher employed traditional talk strategies to build science themes, while students enacted their roles as compliant

  4. Students' Multimodal Construction of the Work-Energy Concept

    NASA Astrophysics Data System (ADS)

    Tang, Kok-Sing; Chee Tan, Seng; Yeo, Jennifer

    2011-09-01

    This article examines the role of multimodalities in representing the concept of work-energy by studying the collaborative discourse of a group of ninth-grade physics students engaging in an inquiry-based instruction. Theorising a scientific concept as a network of meaning relationships across semiotic modalities situated in human activity, this article analyses the students' interactions through their use of natural language, mathematical symbolism, depiction, and gestures, and examines the intertextual meanings made through the integration of these modalities. Results indicate that the thematic integration of multimodalities is both difficult and necessary for students in order to construct a scientific understanding that is congruent with the physics curriculum. More significantly, the difficulties in multimodal integration stem from the subtle differences in the categorical, quantitative, and spatial meanings of the work-energy concept whose contrasts are often not made explicit to the students. The implications of these analyses and findings for science teaching and educational research are discussed.

  5. Constructive evaluation: a pedagogy of student-contributed assessment

    NASA Astrophysics Data System (ADS)

    Luxton-Reilly, Andrew; Denny, Paul

    2010-06-01

    We present an innovative pedagogical approach that we call constructive evaluation, which shifts students from being consumers of knowledge to participants in a community of peers engaged in actively producing and sharing knowledge. Students are required to author a question that assesses one or more of the learning outcomes of a course. In addition to the question, students write a sample solution. These questions and solutions are stored in a question item bank where they become available for other students to use as a learning resource. Once a student answers a question from the item bank, they can see how other students have answered the question and can reflect on their own response. Additionally, students must review the questions they have answered and are given an opportunity to engage in discussion of questions or answers via a feedback mechanism. In addition to improving content knowledge, students develop important meta-skills such as organising and communicating knowledge; judging the quality of information; giving and receiving feedback and improving self-assessment skills. This approach is aligned with both reflective professional practice and social theories of learning.

  6. The relation between children’s constructive play activities, spatial ability, and mathematical word problem-solving performance: a mediation analysis in sixth-grade students

    PubMed Central

    Oostermeijer, Meike; Boonen, Anton J. H.; Jolles, Jelle

    2014-01-01

    The scientific literature shows that constructive play activities are positively related to children’s spatial ability. Likewise, a close positive relation is found between spatial ability and mathematical word problem-solving performances. The relation between children’s constructive play and their performance on mathematical word problems is, however, not reported yet. The aim of the present study was to investigate whether spatial ability acted as a mediator in the relation between constructive play and mathematical word problem-solving performance in 128 sixth-grade elementary school children. This mediating role of spatial ability was tested by utilizing the current mediation approaches suggested by Preacher and Hayes (2008). Results showed that 38.16% of the variance in mathematical word problem-solving performance is explained by children’s constructive play activities and spatial ability. More specifically, spatial ability acted as a partial mediator, explaining 31.58% of the relation between constructive play and mathematical word problem-solving performance. PMID:25101038

    As researchers learn better ways to promote student learning in introductory physics, students learn better ways of circumventing these strategies. Many students remain motivated primarily to find the lowest energy output required to pass a course rather than to actually work at learning physics. We are redesigning our introductory courses, which are taught in a studio format, under the assumption that most students will do only the things they get credit for. By offering incentives for students to participate actively in the learning process, we expect to see an improvement in student performance. This poster describes both the studio format and the teaching strategies being implemented.

    2012-07-01

    This work presents the results of radon concentration measurements of construction materials used in the Brazilian industry, such as clay (red) bricks and concrete blocks. The measurements focused on the detection of indoor radon activity during different construction stages and the analysis of radionuclides present in the construction materials. For this purpose, sealed chambers with internal dimensions of approximately 60×60×60 cm3 were built within a protected and isolated laboratory environment, and stable air humidity and temperature levels were maintained. These chambers were also used for radon emanation reduction tests. The chambers were built in four major stages: (1) assembly of the walls using clay (red) bricks, concrete blocks, and mortar; (2) installation of plaster; (3) finishing of wall surface using lime; and (4) insulation of wall surface and finishing using paint. Radon measurements were performed using polycarbonate etched track detectors. By comparing the three layers applied to the masonry walls, it was concluded that only the last step (wall painting using acrylic varnish) reduced the radon emanation, by a factor of approximately 2. Samples of the construction materials (clay bricks and concrete blocks) were ground, homogenized, and subjected to gamma-ray spectrometry analysis to evaluate the activity concentrations of 226Ra, 232Th and 40K. The values for the index of the activity concentration (I), radium equivalent activity (Raeq), and external hazard index (Hext) showed that these construction materials could be used without restrictions or concern about the equivalent dose limit (1 mSv/year).

  11. Risk compensation behaviours in construction workers' activities.

    PubMed

    Feng, Yingbin; Wu, Peng

    2015-01-01

    The purpose of this study was to test whether the construction workers have the tendency of engaging in risk compensation behaviours, and identify the demographic variables, which may influence the extent to which the construction workers may show risk compensation behaviours. Both quantitative (survey) and qualitative (interviews) approaches were used in this study. A questionnaire survey was conducted with all the construction workers on three building construction sites of a leading construction company in Australia. Semi-structured interviews were then conducted to validate the findings of the quantitative research. The findings indicate that workers tend to show risk compensation behaviours in the construction environment. The workers with more working experience, higher education, or having never been injured at work before have a higher tendency to show risk compensation in their activities than the others. The implication is that contractors need to assess the potential influence of workers' risk compensation behaviours when evaluating the effect of risk control measures. It is recommended that supervisors pay more attention to the behavioural changes of those workers who have more experience, higher education, and have never been injured before after the implementation of new safety control measures on construction site.

Both quantitative (survey) and qualitative (interviews) approaches were used in this study. A questionnaire survey was conducted with all the construction workers on three building construction sites of a leading construction company in Australia. Semi-structured interviews were then conducted to validate the findings of the quantitative research. The findings indicate that workers tend to show risk compensation behaviours in the construction environment. The workers with more working experience, higher education, or having never been injured at work before have a higher tendency to show risk compensation in their activities than the others. The implication is that contractors need to assess the potential influence of workers' risk compensation behaviours when evaluating the effect of risk control measures. It is recommended that supervisors pay more attention to the behavioural changes of those workers who have more experience, higher education, and have never been injured before after the implementation of new safety control measures on construction site.

  17. Computer-based assessment of student-constructed responses.

    Magliano, Joseph P; Graesser, Arthur C

    2012-09-01

    Student-constructed responses, such as essays, short-answer questions, and think-aloud protocols, provide a valuable opportunity to gauge student learning outcomes and comprehension strategies. However, given the challenges of grading student-constructed responses, instructors may be hesitant to use them. There have been major advances in the application of natural language processing of student-constructed responses. This literature review focuses on two dimensions that need to be considered when developing new systems. The first is type of response provided by the student-namely, meaning-making responses (e.g., think-aloud protocols, tutorial dialogue) and products of comprehension (e.g., essays, open-ended questions). The second corresponds to considerations of the type of natural language processing systems used and how they are applied to analyze the student responses. We argue that the appropriateness of the assessment protocols is, in part, constrained by the type of response and researchers should use hybrid systems that rely on multiple, convergent natural language algorithms.

  4. What Do Students "Construct" According to Constructivism in Science Education?

    NASA Astrophysics Data System (ADS)

    Bächtold, Manuel

    2013-12-01

    This paper aims at shedding light on what students can "construct" when they learn science and how this construction process may be supported. Constructivism is a pluralist theory of science education. As a consequence, I support, there are several points of view concerning this construction process. Firstly, I stress that constructivism is rooted in two fields, psychology of cognitive development and epistemology, which leads to two ways of describing the construction process: either as a process of enrichment and/or reorganization of the cognitive structures at the mental level, or as a process of building or development of models or theories at the symbolic level. Secondly, I argue that the usual distinction between "personal constructivism" (PC) and "social constructivism" (SC) originates in a difference of model of reference: the one of PC is Piaget's description of "spontaneous" concepts, assumed to be constructed by students on their own when interacting with their material environment, the one of SC is Vygotsky's description of scientific concepts, assumed to be introduced by the teacher by means of verbal communication. Thirdly, I support the idea that, within SC, there are in fact two trends: one, in line with Piaget's work, demonstrates how cooperation among students affects the development of each individual's cognitive structures; the other, in line with Vygotsky's work, claims that students can understand and master new models only if they are introduced to the scientific culture by their teacher. Fourthly, I draw attention to the process of "problem construction" identified by some French authors. Finally, I advocate for an integrated approach in science education, taking into account all the facets of science learning and teaching mentioned above and emphasizing their differences as well as their interrelations. Some suggestions intended to improve the efficiency of science teaching are made.

    In this poster, we present the results of several activities developed for the general science student to explore infrared light. The first activity involved measuring infrared radiation using an updated version of Newton's experiment of splitting white light and finding IR radiation. The second used Leslie's cube to allow students to observe different radiators, while the third used a modern infrared thermometer to measure and identify IR sources in an enclosed box. The last activity involved students making false-color images from narrow-band filter images from data sets from Spitzer Space Telescope, STScI Digitized Sky Survey and other sources. Using computer programs like Adobe Photoshop and free software such as ds9, Spot and Leopard, poster-like images were created by the students. This research is funded by the Spitzer Science Center (SSC) and the National Optical Astronomy Observatory (NOAO).

  11. Body talk: students' identity construction while discussing a socioscientific issue

    NASA Astrophysics Data System (ADS)

    Ideland, Malin; Malmberg, Claes

    2012-06-01

    Vision II school science is often stated to be a democratic and inclusive form of science education. But what characterizes the subject who fits into the Vision II school science? Who is the desirable student and who is constructed as ill-fitting? This article explores discourses that structure the Vision II science classroom, and how different students construct their identities inside these discourses. In the article we consider school science as an order of discourses which restricts and enables what is possible to think and say and what subject-positions those are available and non-available. The results show that students' talk about a SSI about body and health is constituted by several discourses. We have analyzed how school science discourse, body discourse and general school discourse are structuring the discussions. But these discourses are used in different ways depending on how the students construct their identities in relation to available subject positions, which are dependent on how students at the same time are "doing" gender and social class. As an example, middle class girls show resistance against SSI-work since the practice is threatening their identity as "successful students". This article uses a sociopolitical perspective in its discussions on inclusion and exclusion in the practice of Vision II. It raises critical issues about the inherited complexity of SSI with meetings and/or collisions between discourses. Even if the empirical results from this qualitative study are situated in specific cultural contexts, they contribute with new questions to ask concerning SSI and Vision II school science.

    2001-01-01

    Providing a meaningful learning environment for each student represents a constant and ongoing challenge for faculty. This objective can be facilitated by active student participation in class interactions. The authors have developed the Constructive Engagement Method (CEM), an integrative method for actively involving students in the learning process. CEM permits students to hone interpersonal skills through the development of interrelated practical applications of critical listening and peer evaluation. The CEM approach introduces a method of student performance evaluation that has been judged as fair and equitable by almost all student participants. CEM fully involves all students, even in classes with very large enrollments. CEM as a teaching strategy utilizes a modified debate format that begins with a period of student preparation followed by a debate between two competing teams. The debate is followed by an evaluation period, during which the non-participating students practice the all-important task of determining the value of each team's investment in the process. CEM comprises five stages as follows: Phase 1--Preparation; Phase 2--Opening Statements; Phase 3--Intense Interaction; Phase 4--Closing Statements; and Phase 5--Evaluation. The CEM methodology has enjoyed strong support among graduate and undergraduate students.

  15. Scene Construction, Visual Foraging, and Active Inference

    PubMed Central

    Mirza, M. Berk; Adams, Rick A.; Mathys, Christoph D.; Friston, Karl J.

    2016-01-01

    This paper describes an active inference scheme for visual searches and the perceptual synthesis entailed by scene construction. Active inference assumes that perception and action minimize variational free energy, where actions are selected to minimize the free energy expected in the future. This assumption generalizes risk-sensitive control and expected utility theory to include epistemic value; namely, the value (or salience) of information inherent in resolving uncertainty about the causes of ambiguous cues or outcomes. Here, we apply active inference to saccadic searches of a visual scene. We consider the (difficult) problem of categorizing a scene, based on the spatial relationship among visual objects where, crucially, visual cues are sampled myopically through a sequence of saccadic eye movements. This means that evidence for competing hypotheses about the scene has to be accumulated sequentially, calling upon both prediction (planning) and postdiction (memory). Our aim is to highlight some simple but fundamental aspects of the requisite functional anatomy; namely, the link between approximate Bayesian inference under mean field assumptions and functional segregation in the visual cortex. This link rests upon the (neurobiologically plausible) process theory that accompanies the normative formulation of active inference for Markov decision processes. In future work, we hope to use this scheme to model empirical saccadic searches and identify the prior beliefs that underwrite intersubject variability in the way people forage for information in visual scenes (e.g., in schizophrenia).

    Flanagan, Mary Ellen; Seixas, Noah; Majar, Maria; Camp, Janice; Morgan, Michael

    2003-01-01

    This study characterized exposure for dust-producing construction tasks. Eight common construction tasks were evaluated for quartz and respirable dust exposure by collecting 113 personal task period samples for cleanup; demolition with handheld tools; concrete cutting; concrete mixing; tuck-point grinding; surface grinding; sacking and patching concrete; and concrete floor sanding using both time-integrating filter samples and direct-reading respirable dust monitors. The geometric mean quartz concentration was 0.10 mg/m(3) (geometric standard deviation [GSD]=4.88) for all run time samples, with 71% exceeding the threshold limit value. Activities with the highest exposures were surface grinding, tuck-point grinding, and concrete demolition (GM[GSD] of 0.63[4.12], 0.22[1.94], and 0.10[2.60], respectively). Factors recorded each minute were task, tool, work area, respiratory protection and controls used, estimated cross draft, and whether anyone nearby was making dust. Factors important to exposure included tool used, work area configuration, controls employed, cross draft, and in some cases nearby dust. More protective respirators were employed as quartz concentration increased, although respiratory protection was found to be inadequate for 42% of exposures. Controls were employed for only 12% of samples. Exposures were reduced with three controls: box fan for surface grinding and floor sanding, and vacuum/shroud for surface grinding, with reductions of 57, 50, and 71%, respectively. Exposures were higher for sweeping compound, box fan for cleanup, ducted fan dilution, and wetted substrate. Construction masons and laborers are frequently overexposed to silica. The usual protection method, respirators, was not always adequate, and engineering control use was infrequent and often ineffective.

    Relatively simple principles can be used to plan and construct de novo proteins that bind redox cofactors and participate in a range of electron-transfer reactions analogous to those seen in natural oxidoreductase proteins. These designed redox proteins are called maquettes. Hydrophobic/hydrophilic binary patterning of heptad repeats of amino acids linked together in a single-chain self-assemble into 4-alpha-helix bundles. These bundles form a robust and adaptable frame for uncovering the default properties of protein embedded cofactors independent of the complexities introduced by generations of natural selection and allow us to better understand what factors can be exploited by man or nature to manipulate the physical chemical properties of these cofactors. Anchoring of redox cofactors such as hemes, light active tetrapyrroles, FeS clusters, and flavins by His and Cys residues allow cofactors to be placed at positions in which electron-tunneling rates between cofactors within or between proteins can be predicted in advance. The modularity of heptad repeat designs facilitates the construction of electron-transfer chains and novel combinations of redox cofactors and new redox cofactor assisted functions. Developing de novo designs that can support cofactor incorporation upon expression in a cell is needed to support a synthetic biology advance that integrates with natural bioenergetic pathways.

  19. Scaffolding Middle School Students' Construction of Scientific Explanations: Comparing a cognitive versus a metacognitive evaluation approach

    NASA Astrophysics Data System (ADS)

    Wang, Chia-Yu

    2015-01-01

    This study investigated the effects of scaffolds as cognitive prompts and as metacognitive evaluation on seventh-grade students' growth of content knowledge and construction of scientific explanations in five inquiry-based biology activities. Students' scores on multiple-choice pretest and posttest and worksheets for five inquiry-based activities were analyzed. The results show that the students' content knowledge in all conditions significantly increased from the pretest to posttest. Incorporating cognitive prompts with the explanation scaffolds better facilitated knowledge integration and resulted in greater learning gains of content knowledge and better quality evidence and reasoning. The metacognitive evaluation instruction improved all explanation components, especially claims and reasoning. This metacognitive approach also significantly reduced students' over- or underestimation during peer-evaluation by refining their internal standards for the quality of scientific explanations. The ability to accurately evaluate the quality of explanations was strongly associated with better performance on explanation construction. The cognitive prompts and metacognitive evaluation instruction address different aspects of the challenges faced by the students, and show different effects on the enhancement of content knowledge and the quality of scientific explanations. Future directions and suggestions are provided for improving the design of the scaffolds to facilitate the construction of scientific explanations.

    This study investigates whether engaging college students ( n = 42) in a knowledge building environment would help them work as a community to construct their collective knowledge of history of science and, accordingly, develop a more informed scientific view. The study adopted mixed-method analyses and data mainly came from surveys and student online discourse recorded in a database. Findings indicate that students' knowledge building activities were conducive to the development of their online collaboration as a learning process and the effective collective knowledge work concerning natural science history as a learning outcome. Moreover, students were able to attain a more constructivist-oriented epistemic view that sees scientific theories as invented, tentative, and improvable objects. Finally, based on course reflection, students also regarded their collective learning experiences in this course as meaningful and productive.

  1. Students' Attitudes Toward Gene Technology: Deconstructing a Construct

    NASA Astrophysics Data System (ADS)

    Gardner, Grant E.; Troelstrup, Angelique

    2015-10-01

    Emergent technologies are commonly characterized as involving cutting-edge developments while lacking wide-scale public implementation. Although currently prevalent in many applications, gene technology is often considered emergent in that the science changes so rapidly. Science educators at all levels of formal education are faced with a unique challenge of facilitating student understanding of gene technology (in comparison with more established content) as well as integrating some of the more controversial socioscientific aspects of such content into the curricula. Much of the literature regarding student understanding of biotechnology has focused on development of student attitudes toward the field and the impact of this on their learning. However, there has, of yet, been no unifying framework in the literature regarding what is meant by attitudes toward gene technology. This article reviews the current scholarship (38 empirical studies published between 1990 and 2011) on the measurement of student attitudes toward biotechnology in order to highlight major themes present within the literature. Items from all reviewed studies were collected, coded, and sorted for construction of a comprehensive instrument representing the conceptualizations of attitudes toward gene technology in all 38 studies. Factor analytic techniques were used as a tool to reduce and categorize measurement items. Results provided a framework of five factors that help describe student attitudes toward biotechnology across all the studies. This emergent framework of factors is proposed as a useful means to standardize the discourse in future research.

    2015-01-01

    Objectives This study was designed to explore the underlying construct of measures of empathy, optimism, and burnout in medical students. Methods Three instruments for measuring empathy (Jefferson Scale of Empathy, JSE); Optimism (the Life Orientation Test-Revised, LOT-R); and burnout (the Maslach Burnout Inventory, MBI, which includes three scales of Emotional Exhaustion, Depersonalization, and Personal Accomplishment) were administered to 265 third-year students at Sidney Kimmel (formerly Jefferson) Medical College at Thomas Jefferson University. Data were subjected to factor analysis to examine relationships among measures of empathy, optimism, and burnout in a multivariate statistical model.  Results Factor analysis (principal component with oblique rotation) resulted in two underlying constructs, each with an eigenvalue greater than one. The first factor involved “positive personality attributes” (factor coefficients greater than .58 for measures of empathy, optimism, and personal accomplishment). The second factor involved “negative personality attributes” (factor coefficients greater than .78 for measures of emotional exhaustion, and depersonalization). Conclusions Results confirmed that an  association exists between empathy in the context of patient care and personality characteristics that are conducive to relationship building, and considered to be  “positive personality attributes,” as opposed to personality characteristics that are considered as “negative personality attributes” that are detrimental to interpersonal relationships. Implications for the professional development of physicians-in-training and in-practice are discussed. PMID:25633650

    Although instructional explanations are commonly provided when learners are introduced to new content, they often fail because they are not integrated into effective learning activities. The recently introduced active-constructive-interactive framework posits an effectiveness hierarchy in which interactive learning activities are at the top; these are then followed by constructive and active learning activities, respectively. Against this background, we combined instructional explanations with different types of prompts that were designed to elicit these learning activities and tested the central predictions of the active-constructive-interactive framework. In Experiment 1, N = 83 students were randomly assigned to one of four combinations of instructional explanations and prompts. To test the active < constructive learning hypothesis, the learners received either (1) complete explanations and engaging prompts designed to elicit active activities or (2) explanations that were reduced by inferences and inference prompts designed to engage learners in constructing the withheld information. Furthermore, in order to explore how interactive learning activities can be elicited, we gave the learners who had difficulties in constructing the prompted inferences adapted remedial explanations with either (3) unspecific engaging prompts or (4) revision prompts. In support of the active < constructive learning hypothesis, we found that the learners who received reduced explanations and inference prompts outperformed the learners who received complete explanations and engaging prompts. Moreover, revision prompts were more effective in eliciting interactive learning activities than engaging prompts. In Experiment 2, N = 40 students were randomly assigned to either (1) a reduced explanations and inference prompts or (2) a reduced explanations and inference prompts plus adapted remedial explanations and revision prompts condition.

    College student alcohol consumption is a major concern, and is known to increase during the celebration of special events. This study examined a student-constructed holiday, State Patty's Day, at a university with a dominant drinking culture using three sources of data - coded data from Facebook groups, daily web surveys from first-year students (N= 227, 51% male, age 18 to 20; 27.3% Hispanic/Latino; of non-Hispanic/Latino, 26.9% of sample European American/White, 19.4% Asian American/Hawaiian/Pacific Islander, 15.9% African American/Black, 10.6% more than one race), and criminal offense data from police records. Results indicated that messages about State Patty's Day on Facebook focused on drinking and social aspects of the holiday, such as the social context of drinking, a sense of belonging to a larger community, and the social norms of drinking. These messages were rarely about consequences and rarely negative. On State Patty's Day, 51% of students consumed alcohol, compared to 29% across other sampled weekend days. Students consumed more drinks (M = 8.2 [SD = 5.3] drinks per State Patty's Day drinker) and were more likely to engage in heavy drinking on State Patty's Day, after controlling for gender, drinking motives, and weekend, demonstrating the event-specific spike in heavy drinking associated with this holiday. The impact of this student-constructed holiday went beyond individual drinking behavior; alcohol-specific and other crime also peaked on State Patty's Day and the day after. Event-specific prevention strategies may be particularly important in addressing these spontaneous, quickly-constructed, and dynamic events. PMID:22685369

    The Center for Space Construction (CSC) at the University of Colorado at Boulder is one of eight University Space Engineering Research Centers established by NASA in 1988. The mission of the center is to conduct research into space technology and to directly contribute to space engineering education. The center reports to the Department of Aerospace Engineering Sciences and resides in the College of Engineering and Applied Science. The college has a long and successful track record of cultivating multi-disciplinary research and education programs. The Center for Space Construction is prominent evidence of this record. At the inception of CSC, the center was primarily founded on the need for research on in-space construction of large space systems like space stations and interplanetary space vehicles. The scope of CSC's research has now evolved to include the design and construction of all spacecraft, large and small. Within this broadened scope, our research projects seek to impact the underlying technological basis for such spacecraft as remote sensing satellites, communication satellites, and other special purpose spacecraft, as well as the technological basis for large space platforms. The center's research focuses on three areas: spacecraft structures, spacecraft operations and control, and regolith and surface systems. In the area of spacecraft structures, our current emphasis is on concepts and modeling of deployable structures, analysis of inflatable structures, structural damage detection algorithms, and composite materials for lightweight structures. In the area of spacecraft operations and control, we are continuing our previous efforts in process control of in-orbit structural assembly. In addition, we have begun two new efforts in formal approach to spacecraft flight software systems design and adaptive attitude control systems. In the area of regolith and surface systems, we are continuing the work of characterizing the physical properties of lunar

    Among the many health issues relevant to college students, overconsumption of alcohol remains a prevalent concern. Circumscribing the drinking habits occurring on campuses are innumerable social norms furthering popular beliefs that alcohol is an inherent part of college life. This case study examines how students encounter, interpret and express the social norms they conceive as constituting their campus culture. Through triangulating ethnographic practices with in-depth interviews, we utilize a narrative lens to explore how students construct meanings and values for alcohol's roles in campus life. Our findings demonstrate how students validate uses of alcohol by coupling its presence with stress, social enhancement, peer responsibility and identity. Moreover, interviewees expressed there being subcultural differences between younger and older students' discourse around alcohol use. We draw from these observations to offer suggestions for engaging students actively in campus interventions that give rise to voices excluded from commonly construed social norms. PMID:26698857

    In an effort to inspire student interest in science and technology, scientists from the Forecast Systems Laboratory, a laboratory within the National Oceanic and Atmospheric Administration's (NOAA) Environmental Research Laboratories, and classroom teachers from the Boulder Valley School District collaborated to produce a series of classroom science activities on meteorology and atmospheric science. We call this series 'Student Activities in Meteorology,' or SAM. The goal is to provide activities that are interesting to students, and at the same time convenient and easy to use for teachers. The activity topics chosen are to incorporate trend setting scientific research and cutting edge technology. Several of the activities focus on the meteorological concerns of the Denver metropolitan area because many of NOAA's research labs are located in Boulder, where much of the research and testing for the region is performed. We believe that these activities are versatile and can be easily integrated into current science, environmental studies, health, social studies, and math curricula.

  8. Traditionally taught students learn; actively engaged students remember

    NASA Astrophysics Data System (ADS)

    Franklin, Scott V.; Sayre, Eleanor C.; Clark, Jessica W.

    2014-08-01

    A common narrative in physics education research is that students taught in lecture-based classes learn less than those taught with activity-based reformed methods. We show this narrative is simplistic and misses important dynamics of student learning. In particular, we find students of both methods show equal short-term learning gains on a conceptual question dealing with electric potential. For traditionally taught students, this learning rapidly decays on a time scale of weeks, vanishing by the time of the typical end-of-term post-test. For students in reform-based classes, however, the knowledge is retained and may even be enhanced by subsequent instruction. This difference explains the many previous pre- and post-test studies that have found minimal learning gains in lecture-based courses. Our findings suggest a more nuanced model of student learning, one that is sensitive to time-dependent effects such as forgetting and interference. In addition, the findings suggest that lecture-based courses, by incorporating aspects designed to reinforce student understanding of previously covered topics, might approach the long-term learning found in research-based pedagogies.

  9. Constructing, Perceiving, and Maintaining Scenes: Hippocampal Activity and Connectivity

    PubMed Central

    Zeidman, Peter; Mullally, Sinéad L.; Maguire, Eleanor A.

    2015-01-01

    In recent years, evidence has accumulated to suggest the hippocampus plays a role beyond memory. A strong hippocampal response to scenes has been noted, and patients with bilateral hippocampal damage cannot vividly recall scenes from their past or construct scenes in their imagination. There is debate about whether the hippocampus is involved in the online processing of scenes independent of memory. Here, we investigated the hippocampal response to visually perceiving scenes, constructing scenes in the imagination, and maintaining scenes in working memory. We found extensive hippocampal activation for perceiving scenes, and a circumscribed area of anterior medial hippocampus common to perception and construction. There was significantly less hippocampal activity for maintaining scenes in working memory. We also explored the functional connectivity of the anterior medial hippocampus and found significantly stronger connectivity with a distributed set of brain areas during scene construction compared with scene perception. These results increase our knowledge of the hippocampus by identifying a subregion commonly engaged by scenes, whether perceived or constructed, by separating scene construction from working memory, and by revealing the functional network underlying scene construction, offering new insights into why patients with hippocampal lesions cannot construct scenes.

    2010-04-01

    This qualitative study is an exploration of 32 urban high school students' narratives about the connection between school, work, and societal expectations of their future success related to their racial and ethnic background. The sample varied along 2 contextual dimensions: participation in a psychoeducational intervention (Tools for Tomorrow) and developmental status (i.e., half the sample were 9th-grade students and the other half were 12th-grade students). Using consensual qualitative research, the narratives revealed 3 major domains: future orientation; students' perceptions of society's expectations based on race and ethnicity; and students' perception of the role of their race and ethnicity in future success. Results reveal that the majority of students endorse a connection between school and work, believe that society holds low expectations for them based on their racial and ethnic background, and cannot predict their future success based on their background.

  13. Examining the construct validity of affective judgments of physical activity measures.

    PubMed

    2016-09-01

    Affective judgments of physical activity have emerged as important predictors of physical activity and interventions targeting affective judgments are a promising approach to improving regular physical activity. Currently, measures assessing a variety of potentially distinct constructs are treated as interchangeable assessments of affective judgments of physical activity. Moreover, little is known about the construct validity of the purported measures of this construct. We review several components of construct validity; highlighting their importance for health psychology research. Then, we examine the construct validity of a wide variety of affective judgment of physical activity measures in MTurk and student samples. Cronbach's alpha for the included measures was uniformly high; however, several scales contained excessively redundant items that ultimately lessen their construct validity. Moreover, dependability estimates for the majority of measures was poor, indicating high levels of transient measurement error. The included measures significantly predicted levels of physical activity; however, their relative predictive power was strongly associated with their dependability. In general, the affective judgment measures demonstrated poor convergent validity suggesting they are not interchangeable and best viewed as assessing distinct, albeit related, constructs. Another important limitation of these measures is that they exhibited poor discriminant validity from exercise self-efficacy, which represents an important theoretical and empirical issue for the field of health behavior research. Overall, the current findings indicate the available affective judgments of physical activity measures are suboptimal, have considerable construct validity limitations, and thereby prevent the further advancement of science, theory, and intervention development in this promising area of research.

Specifically, both a structure level as well as a function level adaptation methodologies are utilized in constructing the network. The functional level adaptation scheme ensures that the "growing" or constructive network has different activation functions for each neuron such that the network may be able to capture the underlying input-output map more effectively. The activation functions considered consist of orthonormal Hermite polynomials. It is shown through extensive simulations that the proposed network yields improved performance when compared to networks having identical sigmoidal activation functions.

    The microscope is familiar to many disciplines, including physics, materials science, chemistry, and the life sciences. It demonstrates fundamental aspects of ray and wave optics, making it an ideal system to help educate students in the basic concepts of optics and in measurement principles and techniques. We present an experimental system developed to teach students the basics of ray and wave optics. The students design, build, and test a light microscope made from optics components. We describe the equipment and the basic measurements that students can perform to develop experimental techniques to understand optics principles. Students measure the magnification and test the resolution of the microscope. The system is open and versatile to allow advanced projects such as epi-fluorescence, total internal reflection fluorescence, and optical trapping. We have used this equipment in an optics course, an advanced laboratory course, and graduate-level training modules.

  9. Using a Socratic Dialog To Help Students Construct Fundamental Concepts

    NASA Astrophysics Data System (ADS)

    Depierro, Ed; Garafalo, Fred; Toomey, Richard T.

    2003-12-01

    The concept of gravitational mass is usually introduced to chemistry students as a measure of the amount of matter in a given object. Although this definition can be useful as a starting point for quantitative investigations in chemistry, it does not refer explicitly to the direct experimental observations upon which the concept is actually based. This traditional approach also misses an opportunity to help students connect observations in the see-touch world with inferences about the atomic realm, and may contribute to the incomplete understanding exhibited by many high school and first-year college students of mass and other fundamental concepts, like weight and density. This paper presents a Socratic dialog between a hypothetical instructor and student, which uses experimental evidence and operational definitions to introduce these concepts. The student's responses are based on those of many individuals in a college freshman chemistry course, and point out the difficulties associated with learning the concepts. The question sequence has evolved to its current form based on student feedback obtained over the course of several years. A theoretical basis for this type of instruction is discussed, as well as the benefits and challenges associated with its application to this particular material.

  11. The concept map as a tool for the collaborative construction of knowledge: A microanalysis of high school physics students

    NASA Astrophysics Data System (ADS)

    Roth, Wolff-Michael; Roychoudhury, Anita

    Although concept mapping has been shown to help students in meaningful learning, particularly when done as a collaborative activity, little has been done to understand the microprocesses during the activity itself. However, in order to be able to improve the activity as a teaching and learning heuristic, we have to know more about the microprocesses that constitute concept mapping as process and as product. This study was designed to investigate concept mapping as a means of assessing the quality of student understanding from two perspectives: the analysis of the process of constructing meaning and the analysis of the products of this cognitive activity. An interpretive research methodology was adopted for the construction of meaning from the data. Twenty-nine students from two sections of a senior level high school physics course participated in the study. The data sources included videotapes, their transcripts, and all concept maps produced. Students worked in collaborative groups during all of the concept mapping sessions. Individual concept mapping was assessed twice, once delayed by a week, another time delayed by 6 weeks. To assess what happened to the cognitive achievement as the context of concept mapping changed from collaborative to individual activity, we used a tracer. A tracer is some bit of knowledge, procedure, or action that allows the researcher to follow a task through various settings. The concept maps as products differed in their hierarchical organization, the number of links, and the benefit to the individual students. Three major processes emerged, which students used to arrive at suitable propositions. Students mediated propositions verbally and nonverbally, they took adversarial positions and appealed to authority, and they formed temporary alliances based on presumed expertise. Both product and process hold promise but also show some limitations. On the positive side, concept mapping led to sustained discourse on the topic and improved the

  10. Astronomy Student Activities Using Stellarium Software

    NASA Astrophysics Data System (ADS)

    Benge, Raymond D.; Tuttle, S. R.

    2012-01-01

    Planetarium programs can be used to provide a valuable learning experience for introductory astronomy students. Educational activities can be designed to utilize the capabilities of the software to display the sky, coordinates, motions in the sky, etc., in order to learn basic astronomical concepts. Most of the major textbook publishers have an option of bundling planetarium software and even laboratory activities using such software with textbooks. However, commercial planetarium software often is updated on a different schedule from the textbook revision and new edition schedule. The software updates also sometimes occur out of sync with college textbook adoption deadlines. Changes in software and activity curriculum often translate into increases costs for students and the college. To provide stability to the process, faculty at Tarrant County College have developed a set of laboratory exercises, entitled Distant Nature, using free open source Stellarium software. Stellarium is a simple, yet powerful, program that is available in formats that run on a variety of operating systems (Windows, Apple, linux). A web site was developed for the Distant Nature activities having a set version of Stellarium that students can download and install on their own computers. Also on the web site, students can access the instructions and worksheets associated with the various Stellarium based activities. A variety of activities are available to support two semesters of introductory astronomy. The Distant Nature web site has been used for one year with Tarrant County College astronomy students and is now available for use by other institutions. The Distant Nature web site is http://www.stuttle1.com/DN_Astro/index.html .

  17. Student Active Learning Methods in Physical Chemistry

    NASA Astrophysics Data System (ADS)

    Hinde, Robert J.; Kovac, Jeffrey

    2001-01-01

    We describe two strategies for implementing active learning in physical chemistry. One involves supplementing a traditional lecture course with heavily computer-based active-learning exercises carried out by cooperative groups in a department computer lab. The other uses cooperative learning almost exclusively, supplemented by occasional mini-lectures. Both approaches seemed to result in better student learning and a more positive attitude toward the subject. On the basis of our respective experiences using active learning techniques, we discuss some of the strengths of these techniques and some of the challenges we encountered using the active-learning approach in teaching physical chemistry.

Class projects explored the effects of varying the content of CO2 and CH4 in the atmosphere, as well as the properties of paleoclimates in atmospheric simulations using EdGCM. Initial assessment of student knowledge, attitudes, and behaviors associated with these activities, particularly about climate change, was measured. Pre- and post-course surveys provided student perspectives about the courses and their learning about remote sensing and climate change concepts. Student performance on the tutorials and course projects evaluated students' ability to learn and apply their knowledge about climate change and skills with remote sensing to assigned problems or proposed projects of their choice. Survey and performance data illustrated that the exercises were successful in meeting their intended learning objectives as well as opportunities for further refinement and expansion.

The previous article published in Sports Medicine dealt with convergent validity (i.e. the extent to which an instrument's output is associated with that of other instruments intended to measure the same exposure of interest). The present focus is on construct validity. Construct validity is the extent to which the measurement corresponds with other measures of theoretically-related parameters. Construct validity is typically evaluated by correlational analysis, that is, the magnitude of concordance between two measures (e.g. pedometer-determined steps/day and a theoretically-related parameter such as age, anthropometric measures and fitness). A systematic literature review produced 29 articles published since > or =1980 directly relevant to construct validity of pedometers in relation to age, anthropometric measures and fitness. Reported correlations were combined and a median r-value was computed. Overall, there was a weak inverse relationship (median r = -0.21) between age and pedometer-determined physical activity. A weak inverse relationship was also apparent with both body mass index and percentage overweight (median r = -0.27 and r = -0.22, respectively). Positive relationships regarding indicators of fitness ranged from weak to moderate depending on the fitness measure utilised: 6-minute walk test (median r = 0.69), timed treadmill test (median r = 0.41) and estimated maximum oxygen uptake (median r = 0.22). Studies are warranted to assess the relationship of pedometer-determined physical activity with other important health-related outcomes including blood pressure and physiological parameters such as blood glucose and lipid profiles. The aggregated evidence of convergent

    The aim of the current article is to give an overview about microbial communities and their functioning but also about factors affecting microbial activity in the three most common types (surface flow and two types of sub-surface flow) of constructed wetlands. The paper reviews the community composition and structural diversity of the microbial biomass, analyzing different aspects of microbial activity with respect to wastewater properties, specific wetland type, and environmental parameters. A brief introduction about the application of different novel molecular techniques for the assessment of microbial communities in constructed wetlands is also given. Microbially mediated processes in constructed wetlands are mainly dependent on hydraulic conditions, wastewater properties, including substrate and nutrient quality and availability, filter material or soil type, plants, and different environmental factors. Microbial biomass is within similar ranges in both horizontal and vertical subsurface flow and surface flow constructed wetlands. Stratification of the biomass but also a stratified structural pattern of the bacterial community can be seen in subsurface flow systems. Microbial biomass C/N ratio is higher in horizontal flow systems compared to vertical flow systems, indicating the structural differences in microbial communities between those two constructed wetland types. The total activity of the microbial community is in the same range, but heterotrophic growth is higher in the subsurface (vertical flow) system compared to the surface flow systems. Available species-specific data about microbial communities in different types of wetlands is scarce and therefore it is impossible make any general conclusions about the dynamics of microbial community structure in wetlands, its relationship to removal processes and operational parameters.

    Activation data for an aluminum target irradiated by 200 MeV/u 238U ion beam are presented in the paper. The target was irradiated in the stacked-foil geometry and analyzed using gamma-ray spectroscopy. The purpose of the experiment was to study the role of primary particles, projectile fragments, and target fragments in the activation process using the depth profiling of residual activity. The study brought information on which particles contribute dominantly to the target activation. The experimental data were compared with the Monte Carlo simulations by the FLUKA 2011.2c.0 code. This study is a part of a research program devoted to activation of accelerator construction materials by high-energy (⩾200 MeV/u) heavy ions at GSI Darmstadt. The experimental data are needed to validate the computer codes used for simulation of interaction of swift heavy ions with matter.

    A visually realistic tornadic supercell thunderstorm has been constructed in a fully immersive virtual reality environment to allow students to better understand the complex small-scale dynamics present in such a storm through data probing. Less-immersive versions have been created that run on PCs, facilitating broader dissemination. The activity has been tested in introductory meteorology classes over the last four years. An exercise involving the virtual storm was first used by a subset of students from a large introductory meteorology course in spring 2002. Surveys were used at that time to evaluate the impact of this activity as a constructivist learning tool. More recently, data probe capabilities were added to the virtual storm activity enabling students to take measurements of temperature, wind, pressure, relative humidity, and vertical velocity at any point within the 3-D volume of the virtual world, and see the data plotted via a graphical user interface. Similar surveys applied to groups of students in 2003 and 2004 suggest that the addition of data probing improved the understanding of storm-scale features, but the improved understanding may not be statistically significant when evaluated using quizzes reflecting short-term retention. The use of the activity was revised in 2005 to first have students pose scientific questions about these storms and think about a scientific strategy to answer their questions before exploring the storm. Once again, scores on quizzes for students who used the virtual storm activity were slightly better than those of students who were exposed to only a typical lecture, but differences were not statistically significant.

    Castro-Tejerina, Jorge

    2014-12-01

    This work aims to analyze the relations between psychology as social engineering and self-reflective citizenship from a historiogenetic point of view. Such a connection was founded during modernity; hence our proposal is to study its operative continuity in the postmodern world, taking into account the mismatches due to the new global, multicultural, and technological conditions. Based both on the theory of activity and the concept of semiosphere, the interaction and discussions of a group of Spanish students of psychology in a virtual forum were analyzed. They were asked to negotiate and co-construct their double condition of citizens and future psychologists in connection with the controversial exhibition of religious symbols in Spanish schools. Results show that students segregate both conditions. On one hand, they agree and consolidate the neutral image of a professional psychologist being respectful with the multicultural world. On the other hand, they argue about the citizen and religious topics from a personal or ideological point of view, establishing limits to multiculturalism. Neither the interchange of ideas nor the writing-reading features of the virtual artefacts improved the reflexivity on the close dependencies and contradictions of the two identity domains. This great resilience is due to a sociocultural context -the Western World- where psychology has been constituted as a neutral, objective Science World, one of whose socio-historical products - reflective citizenship- has evolved until proclaiming his/her autonomous agency, forgetting any root in the social engineering.

    The two main purposes of the present study were to construct the self-motivational strategies scale for junior high school students, and to examine the validity of the scale. In the first study, from the result of factor analysis on the data of 449 students, eight subscales were constructed, and differences in subscale scores between grades were found. In the second study, the relationships among eight self-motivational strategies, four types of motivation, academic stress coping strategies and appraisal of academic stressors were examined. It was shown that different aspects of students' self-motivational strategy were differentially related to their academic motivation and the use of some stress coping strategies. In addition, covariance structure analysis was carried out to investigate the validity of the scale. The results supported the construct validity of all but one of the subscales. PMID:14584251

    The paper deals with the mechanical grinding down to the nano powder of construction materials. During mechanical activation a composite binder active molecules cement minerals occur in the destruction of the molecular defects in the areas of packaging and breaking metastable phase decompensation intermolecular forces. The process is accompanied by a change in the kinetics of hardening of portland cement. Mechanical processes during grinding mineral materials cause, along with the increase in their surface energy, increase the Gibbs energy of powders and, respectively, their chemical activity, which also contributes to the high adhesion strength when contacting them with binders. Thus, the set of measures for mechanical activation makes better use of the weight of components filled with cement systems and adjust their properties. At relatively low cost is possible to provide a spectacular and, importantly, easily repeatable results in a production environment.

    Nguyen, Huy Van; Giang, Thao Thach

    2013-01-01

    Background In Vietnam, as doctor of medicine is socially considered a special career, both men and women who are enrolled in medical universities often study topics of medicine seriously. However, as culturally expected, women often perform better than men. Because of this, teaching leadership and management skill (LMS) to develop academic planning activity (APA) for female medical students would also be expected to be more effective than male counterparts. This research aimed to compare by gender the effect of teaching LMS on increasing APA, using propensity score matching (PSM). Methods In a cross-sectional survey utilizing a self-reported structured questionnaire on a systematic random sample of 421 male and female medical students in Hanoi Medical University, this study adopted first regression techniques to construct a fit model, then PSM to create a matched control group in order to allow for evaluating the effect of LMS education. Results There were several interesting gender differences. First, while for females LMS education had both direct and indirect effects on APA, it had only direct effect on males’ APA. Second, after PSM to adjust for the possible confounders to balance statistically two groups – with and without LMS education, there is statistically a significant difference in APA between male and female students, making a net difference of 11% (p<.01), equivalent to 173 students. The difference in APA between exposed and matched control group in males and females was 9% and 20%, respectively. These estimates of 9.0 and 20.0 percentage point increase can be translated into the practice of APA by 142 males and 315 females, respectively, in the population. These numbers of APA among male and female students can be explained by LMS education. Conclusions Gender appears to be a factor explaining in part academic planning activity. PMID:23418467

    College student alcohol consumption is a major concern, and is known to increase during the celebration of special events. This study examined a student-constructed holiday, State Patty’s Day, at a university with a dominant drinking culture using three sources of data – coded data from Facebook groups, daily web surveys from first-year students (N= 227, 51% male, age 18 to 20; 27.3% Hispanic/Latino; of non-Hispanic/Latino, 26.9% of sample European American/White, 19.4% Asian American/Hawaiian/Pacific Islander, 15.9% African American/Black, 10.6% more than one race), and criminal offense data from police records. Results indicated that messages about State Patty’s Day on Facebook focused on drinking and social aspects of the holiday, such as the social context of drinking, a sense of belonging to a larger community, and the social norms of drinking. These messages were rarely about consequences and rarely negative. On State Patty’s Day, 51% of students consumed alcohol, compared to 29% across other sampled weekend days. Students consumed more drinks (M = 8.2 [SD = 5.3] drinks per State Patty’s Day drinker) and were more likely to engage in heavy drinking on State Patty’s Day, after controlling for gender, drinking motives, and weekend, demonstrating the event-specific spike in heavy drinking associated with this holiday. The impact of this student-constructed holiday went beyond individual drinking behavior; alcohol-specific and other crime also peaked on State Patty’s Day and the day after. Event-specific prevention strategies may be particularly important in addressing these spontaneous, quickly-constructed, and dynamic events. PMID:22685369

    2004-09-01

    This study employed problem-based learning for project work in a year 9 biology class. The purpose of the study was to investigate (a) students' inspirations for their self-generated problems and questions, (b) the kinds of questions that students asked individually and collaboratively, and (c) how students' questions guided them in knowledge construction. Data sources included observation and field notes, students' written documents, audiotapes and videotapes of students working in groups, and student interviews. Sources of inspiration for students' problems and questions included cultural beliefs and folklore; wonderment about information propagated by advertisements and the media; curiosity arising from personal encounters, family members' concerns, or observations of others; and issues arising from previous lessons in the school curriculum. Questions asked individually pertained to validation of common beliefs and misconceptions, basic information, explanations, and imagined scenarios. The findings regarding questions asked collaboratively are presented as two assertions. Assertion 1 maintained that students' course of learning were driven by their questions. Assertion 2 was that the ability to ask the right'' questions and the extent to which these could be answered, were important in sustaining students' interest in the project. Implications of the findings for instructional practice are discussed.

  17. Predators of knowledge construction: Interpreting students' metacognition in an amusement park physics program

    NASA Astrophysics Data System (ADS)

    Anderson, David; Nashon, Samson

    2007-03-01

    It is recognized widely that learning is a dynamic and idiosyncratic process of construction and reconstruction of concepts in response to new experiences. It is influenced by the learner's prior knowledge, motivation, and sociocultural context. This study investigated how year 11 and 12 physics students' metacognition influences the development of their conceptual understandings of kinematics. An interpretive case study approach was used to investigate students working in collaborative groups in the context of an amusement park physics program. The metacognitive character of individual learners was demonstrated to have a strong influence on their conceptual development. Moreover, the metacognitive character of individuals within the small group contexts investigated was a key factor influencing the groups' collective knowledge development. A coyote-rabbit metaphor was developed to interpret the resilience and weaknesses of individual and group knowledge construction processes, and elucidates new theoretical understandings regarding metacognition and its influence on knowledge construction.

  4. The nature of middle school students' knowledge construction and scientific reasoning during inquiry in genetics

    NASA Astrophysics Data System (ADS)

    Echevarria, Marissa

    1999-11-01

    The purpose of this study was to examine the nature of middle school students' scientific reasoning and knowledge construction during a three-week inquiry unit in genetics. During the unit, students used genetics simulation software to investigate how traits were transmitted in fruit flies and plants in order to develop mental models of trait transmission for simple dominance single trait inheritance patterns. Using a participant/observer design, data were collected consisting of a pretest/posttest assessment, audiotaped/videotaped discourse, computer logs, student recorded logs, homework, final reports, and researcher field notes. Qualitative analyses were used to determine categories of student content knowledge and scientific reasoning. For content knowledge, categories of student explanations were formed for both standard and anomalous inheritance patterns. Standard inheritance patterns were those that could be predicted based on the appearance of the parents. Anomalous inheritance patterns were those that could not. For scientific reasoning, categories of student hypotheses, tests, and conclusions were formed. Quantitative analyses were used to determine patterns of significance in the qualitative data. Based on pre-post analyses, students made a significant shift from less sophisticated to more sophisticated explanations of anomalous inheritance patterns. Changes in scientific reasoning were more subtle. Some students shifted from less complex to more complex hypotheses, and from descriptive to evaluative conclusions. Some students also shifted from less comprehensive to more comprehensive testing. Student ability to explain two different anomalous patterns seemed to be linked to the extent to which they encountered each anomalous outcome during their investigations; greater exposure was associated with an increased number of students being able to explain that pattern. Novice tendencies found in the extant literature on students' lack of systematicity during

  5. Active and emotional student engagement: a nationwide, prospective, longitudinal study of Swedish nursing students.

    PubMed

    Bruce, Malin; Omne-Pontã N, Marianne; Gustavsson, Petter J

    2010-01-01

    The researchers surveyed nursing students yearly during their three-year education, and examined active and emotional engagement. We examined the association of these properties with seven independent variables: higher educational institution, class size, age, gender, prior assistant nurse education, study experience and self-rated health. This longitudinal study included 1,334 students from 24 universities and university colleges in Sweden. Active engagement increased and emotional engagement decreased during the study years. Male students, older students and those with prior assistant nurse education had higher active engagement than other students. Older students, females, students with good self-rated health and those attending universities had higher emotional engagement. Study results suggest that higher educational institutions should pay more attention to students' active and emotional engagement in learning situations, since this may increase the ability of the students to cope with stressful events during their education, giving them an extra resource on which they can draw.

  12. Bioglass Activated Skin Tissue Engineering Constructs for Wound Healing.

    PubMed

    Yu, Hongfei; Peng, Jinliang; Xu, Yuhong; Chang, Jiang; Li, Haiyan

    2016-01-13

    Wound healing is a complicated process, and fibroblast is a major cell type that participates in the process. Recent studies have shown that bioglass (BG) can stimulate fibroblasts to secrete a multitude of growth factors that are critical for wound healing. Therefore, we hypothesize that BG can stimulate fibroblasts to have a higher bioactivity by secreting more bioactive growth factors and proteins as compared to untreated fibroblasts, and we aim to construct a bioactive skin tissue engineering graft for wound healing by using BG activated fibroblast sheet. Thus, the effects of BG on fibroblast behaviors were studied, and the bioactive skin tissue engineering grafts containing BG activated fibroblasts were applied to repair the full skin lesions on nude mouse. Results showed that BG stimulated fibroblasts to express some critical growth factors and important proteins including vascular endothelial growth factor, basic fibroblast growth factor, epidermal growth factor, collagen I, and fibronectin. In vivo results revealed that fibroblasts in the bioactive skin tissue engineering grafts migrated into wound bed, and the migration ability of fibroblasts was stimulated by BG. In addition, the bioactive BG activated fibroblast skin tissue engineering grafts could largely increase the blood vessel formation, enhance the production of collagen I, and stimulate the differentiation of fibroblasts into myofibroblasts in the wound site, which would finally accelerate wound healing. This study demonstrates that the BG activated skin tissue engineering grafts contain more critical growth factors and extracellular matrix proteins that are beneficial for wound healing as compared to untreated fibroblast cell sheets.

    OBJECTIVE Translate the Patient-centered Assessment and Counseling for Exercise questionnaire, adapt it cross-culturally and identify the psychometric properties of the psychosocial scales for physical activity in young university students. METHODS The Patient-centered Assessment and Counseling for Exercise questionnaire is made up of 39 items divided into constructs based on the social cognitive theory and the transtheoretical model. The analyzed constructs were, as follows: behavior change strategy (15 items), decision-making process (10), self-efficacy (6), support from family (4), and support from friends (4). The validation procedures were conceptual, semantic, operational, and functional equivalences, in addition to the equivalence of the items and of measurements. The conceptual, of items and semantic equivalences were performed by a specialized committee. During measurement equivalence, the instrument was applied to 717 university students. Exploratory factor analysis was used to verify the loading of each item, explained variance and internal consistency of the constructs. Reproducibility was measured by means of intraclass correlation coefficient. RESULTS The two translations were equivalent and back-translation was similar to the original version, with few adaptations. The layout, presentation order of the constructs and items from the original version were kept in the same form as the original instrument. The sample size was adequate and was evaluated by the Kaiser-Meyer-Olkin test, with values between 0.72 and 0.91. The correlation matrix of the items presented r < 0.8 (p < 0.05). The factor loadings of the items from all the constructs were satisfactory (> 0.40), varying between 0.43 and 0.80, which explained between 45.4% and 59.0% of the variance. Internal consistency was satisfactory (α ≥ 0.70), with support from friends being 0.70 and 0.92 for self-efficacy. Most items (74.3%) presented values above 0.70 for the reproducibility test

  17. The cultural construction of interdisciplinarity: Doctoral student socialization in an interdisciplinary neuroscience program

    NASA Astrophysics Data System (ADS)

    Holley, Karri A.

    Using the methodologies of individual and group interviews, observation, and document analysis, this dissertation examines the experiences of doctoral students enrolled in an interdisciplinary neuroscience program. A framework drawn from theories of organizational socialization is employed to understand the influence of an interdisciplinary program on doctoral student socialization. While abundant previous literature exists in regards to the socialization of doctoral students, such literature largely concentrates the disciplinary experience. The escalating import of globalization and shifting fiscal realities place new demands on Ph.D. programs and doctoral students to work as part of collaborative research teams, produce interdisciplinary knowledge, and integrate theory and practice. The increasing influence of such factors requires a new focus on interdisciplinarity and the changing Ph.D. The goal of this dissertation is to expand the existing framework of socialization by documenting the influence of such obstacles on knowledge acquisition, identity development, and professional investment. This study focuses on how interdisciplinary identities are constructed by doctoral students through individual interaction with the social environment and cultural context. Particular attention is given to the structural and cultural obstacles that doctoral students must negotiate as they navigate an interdisciplinary program. The study expands on the previous literature regarding doctoral student socialization by focusing on identity development, specifically a student's symbolic identity as a neuroscientist, a student's disciplinary identity (related to her professional background and undergraduate experiences), and a multi-disciplinary identity that allows for connections across disciplinary boundaries. In contrast to the traditional concepts of identity which focus on boundaries and differences as an inherent part of self-definition, the structure of identity advanced

    Chaney, Robert A; Bernard, Amy L; Wilson, Bradley R A

    2013-01-01

    Physical inactivity poses concern for health risks among all groups in the United States. Active transportation (AT) (e.g., bicycling) is one way of being physically active and may be helpful in promoting physical activity. This study characterized active transportation behavior among college students using the Theory of Planned Behavior. This study sought to describe predictors, including Theory of Planned Behavior (TPB) constructs, of AT behavior among college students at a large Midwest university. Students were recruited through the university registrar's office and e-mailed an electronic survey. Differences among AT users were determined using t-tests, and predictors of AT were identified using regression analysis. Significant differences between AT users for all TPB constructs were observed. Regression analysis using only TPB constructs accounted for 11.58% explained variation in AT use. Other variables added to the model resulted in 44.44% explained variation in AT use. The final model included subjective norms, age, perceived behavioral control, and transportation type and destination. The results of this research are insightful in explaining AT behavior. Perceived norms and the level of control students had regarding their method of transportation were important contributions to AT use. These results may be applied to promoting physical activity in community health.

    2013-06-01

    The purpose of this analysis is to describe the variation in students' reports of engagement in science across science teaching and learning activities. In addition, this study examines student and school characteristics that may be associated with students' levels of engagement in science. Data are drawn from the Programme for International Student Assessment 2006 study. The analysis employs a quantitative approach that includes descriptive and inferential statistics to examine three measures of student engagement for a nationally representative sample of approximately 12,000 15-year-old students in the UK. The main results indicate that there is an association between students' motivation towards science, enjoyment of science and future orientation towards science, and the frequency in which various teaching and learning activities take place in the classroom. Understanding student engagement in science and the factors that influence it is essential in addressing the issue of uptake of science after compulsory schooling.

    Wang, Tzu-Ling; Berlin, Donna

    2010-12-01

    The main purpose of this study is to develop a valid and reliable instrument for measuring the attitudes toward science class of fourth- and fifth-grade students in an Asian school culture. Specifically, the development focused on three science attitude constructs-science enjoyment, science confidence, and importance of science as related to science class experiences. A total of 265 elementary school students in Taiwan responded to the instrument developed. Data analysis indicated that the instrument exhibited satisfactory validity and reliability with the Taiwan population used. The Cronbach's alpha coefficient was 0.93 for the entire instrument indicating a satisfactory level of internal consistency. However, both principal component analysis and parallel analysis showed that the three attitude scales were not unique and should be combined and used as a general "attitudes toward science class" scale. The analysis also showed that there were no gender or grade-level differences in students' overall attitudes toward science class.

    2007-01-01

    Purpose To test self-regulation concepts in relation to dietary intake and physical activity patterns in adolescence, which we predicted to be influenced by components of a self-control model. Methods A survey was conducted with a multiethnic sample of 9th grade public school students in a metropolitan area (N = 539). Confirmatory analysis tested the measurement structure of self-control. Structural equation modeling tested the association of self-control constructs with measures of fruit and vegetable intake, saturated-fat intake, physical activity, and sedentary behavior. Results Confirmatory analysis of 14 indicators of self-control showed best fit for a two-factor structure, with latent constructs of good self-control (planfulness) and poor self-control (impulsiveness). Good self-control was related to more fruit and vegetable intake, more participation in sports, and less sedentary behavior. Poor self-control was related to more saturated-fat intake and less vigorous exercise. These effects were independent of gender, ethnicity, and parental education, which themselves had relations to diet and exercise measures. Multiple-group modeling indicated that effects of self-control were comparable across gender and ethnicity subgroups. Conclusions Self-control concepts are relevant for patterns of dietary intake and physical activity among adolescents. Attention to self-control processes may be warranted for prevention programs to improve health behaviors in childhood and adolescence. PMID:18023783

    2015-06-01

    With the aim of advancing the literature on impression management in physical activity settings, we developed a theoretically derived 2 by 2 instrument that was designed to measure different types of context-specific self-presentation motives. Following item generation and expert review (Study 1), the instrument was completed by 206 group exercise class attendees (Study 2) and 463 high school physical education students (Study 3). Our analyses supported the intended factor structure (i.e., reflecting acquisitive-agentic, acquisitive-communal, protective-agentic, and protective-communal motives). We found some support for construct validity, and the self-presentation motives were associated with variables of theoretical and applied interest (e.g., impression motivation and construction, social anxiety, social and achievement goals, efficacy beliefs, engagement). Taken together, the results indicate that the Self-presentation Motives for Physical Activity Questionnaire (SMPAQ) may be useful for measuring various types of self-presentation motives in physical activity settings.

    2000-01-01

    Science education is taking the teaching of science from a traditional (lecture) approach to a multidimensional sense-making approach which allows teachers to support students by providing exploratory experiences. Using projects is one way of providing students with opportunities to observe and participate in sense-making activity. We created a learning environment that fostered inquiry-based learning. Students were engaged in a variety of Inquiry activities that enabled them to work in cooperative planning teams where respect for each other was encouraged and their ability to grasp, transform and transfer information was enhanced. Summer, 1998: An air pollution workshop was conducted for high school students in the Medgar Evers College/Middle College High School Liberty Partnership Summer Program. Students learned the basics of meteorology: structure and composition of the atmosphere and the processes that cause weather. The highlight of this workshop was the building of hand-held sunphotometers, which measure the intensity of the sunlight striking the Earth. Summer, 1999: high school students conducted a research project which measured the mass and size of ambient particulates and enhanced our ability to observe through land based measurements changes in the optical depth of ambient aerosols over Brooklyn. Students used hand held Sunphotometers to collect data over a two week period and entered it into the NASA GISS database by way of the internet.

  16. Students' Learning Activities While Studying Biological Process Diagrams

    NASA Astrophysics Data System (ADS)

    Kragten, Marco; Admiraal, Wilfried; Rijlaarsdam, Gert

    2015-08-01

    Process diagrams describe how a system functions (e.g. photosynthesis) and are an important type of representation in Biology education. In the present study, we examined students' learning activities while studying process diagrams, related to their resulting comprehension of these diagrams. Each student completed three learning tasks. Verbal data and eye-tracking data were collected as indications of students' learning activities. For the verbal data, we applied a fine-grained coding scheme to optimally describe students' learning activities. For the eye-tracking data, we used fixation time and transitions between areas of interest in the process diagrams as indices of learning activities. Various learning activities while studying process diagrams were found that distinguished between more and less successful students. Results showed that between-student variance in comprehension score was highly predicted by meaning making of the process arrows (80%) and fixation time in the main area (65%). Students employed successful learning activities consistently across learning tasks. Furthermore, compared to unsuccessful students, successful students used a more coherent approach of interrelated learning activities for comprehending process diagrams.

  1. Active fault database of Japan: Its construction and search system

    NASA Astrophysics Data System (ADS)

    Yoshioka, T.; Miyamoto, F.

    2011-12-01

    The Active fault database of Japan was constructed by the Active Fault and Earthquake Research Center, GSJ/AIST and opened to the public on the Internet from 2005 to make a probabilistic evaluation of the future faulting event and earthquake occurrence on major active faults in Japan. The database consists of three sub-database, 1) sub-database on individual site, which includes long-term slip data and paleoseismicity data with error range and reliability, 2) sub-database on details of paleoseismicity, which includes the excavated geological units and faulting event horizons with age-control, 3) sub-database on characteristics of behavioral segments, which includes the fault-length, long-term slip-rate, recurrence intervals, most-recent-event, slip per event and best-estimate of cascade earthquake. Major seismogenic faults, those are approximately the best-estimate segments of cascade earthquake, each has a length of 20 km or longer and slip-rate of 0.1m/ky or larger and is composed from about two behavioral segments in average, are included in the database. This database contains information of active faults in Japan, sorted by the concept of "behavioral segments" (McCalpin, 1996). Each fault is subdivided into 550 behavioral segments based on surface trace geometry and rupture history revealed by paleoseismic studies. Behavioral segments can be searched on the Google Maps. You can select one behavioral segment directly or search segments in a rectangle area on the map. The result of search is shown on a fixed map or the Google Maps with information of geologic and paleoseismic parameters including slip rate, slip per event, recurrence interval, and calculated rupture probability in the future. Behavioral segments can be searched also by name or combination of fault parameters. All those data are compiled from journal articles, theses, and other documents. We are currently developing a revised edition, which is based on an improved database system. More than ten

    the need to implement efforts that are sustainable and affordable. One area NASA is developing that can significantly change how systems required for sustained human presence are designed and integrated, as well as potentially break our reliance on Earth supplied logistics, is In-Situ Resource Utilization (ISRU). ISRU, also known living off the land, involves the extraction and processing of local resources into useful products. In particular, the ability to make propellants, life support consumables, fuel cell reagents, and radiation shielding can significantly reduce the cost, mass, and risk of sustained human activities beyond Earth. Also, the ability to modify the lunar landscape for safer landing, transfer of payloads from the lander an outpost, dust generation mitigation, and infrastructure placement and buildup are also extremely important for long-term lunar operations. While extra-terrestrial excavation, material handling and processing, and site preparation and construction may be new to NASA and other space agencies, there is extensive terrestrial hardware and commercial experience that can be leveraged. This paper will provide an overview of current NASA activities in lunar ISRU mining and construction and how terrestrial experience in these areas are important to achieving the goal of affordable and sustainable human exploration.

  18. Middle school students' conceptual change in global climate change: Using argumentation to foster knowledge construction

    NASA Astrophysics Data System (ADS)

    Golden, Barry W.

    their explanations could be modified to better account for the data as pointed out by peers. As the students experienced the three lessons comprising the unit, data were taken of various modes, including pre-unit, mid-unit, post-unit, and delayed-post unit interviews, observer notes from the classroom, and artifacts created by the students as individuals and as members of a group. At the end of the unit, a written post-assessment was administered, and post-interviews were conducted with the selected students. These varied data sources were analyzed in order to develop themes corresponding to their frameworks of climate change. Negative cases were sought in order to test developing themes. Themes that emerged from the data were triangulated across the various data sources in order to ensure quality and rigor. These themes were then used to construct understandings of various students' frameworks of the content. Several findings emerged from this research. The first finding is that each student underwent some conceptual change regarding GCC, although of varying natures. The students' synthetic frameworks of GCC were more complex than their initial, or naive frameworks. Some characteristics of the naive frameworks included that the students tended to conflate climate change with a broader, generic category of environmental things. Examples of this conflation include the idea that climate change entails general pollution, litter, and needless killing of dolphins while fishing for tuna. This research suggests that students might benefit from explicit attention to this concept in terms of an ontological category, with the ideal synthetic view realizing that GCC is itself an example of an emergent process. Another characteristic of their naive frameworks includes some surprisingly accurate notions of GCC, including a general sense that temperatures and sea levels are rising. At the same time, none of the students were able to adequately invoke data to support their

  20. What counts as knowing: Constructing a communicative repertoire for student demonstration of knowledge in science

    NASA Astrophysics Data System (ADS)

    Crawford, Teresa

    2005-02-01

    The purpose of this study was twofold. One purpose was to identify the locally negotiated literate practices that defined ways of communicating information and knowledge across the curriculum in a fourth/fifth grade classroom. Through an ethnographic and sociolinguistic set of analyses, this investigation illustrated how the teacher worked to construct a learning environment that valued the use of multiple discourses as a way of communicating competence as a learner. Another purpose was specifically to address the ways that these practices contributed to student demonstration of knowledge in science. This was accomplished by an analysis of one student's presentation of science knowledge after a study of simple machines. A comparative analysis between his use of two discourses, written and oral, showed that the opportunity to choose between multiple discourses led to his success in demonstrating competence in ways that may have otherwise remained questionable.

  10. Preparing students to participate in an active learning environment.

    PubMed

    Modell, H I

    1996-06-01

    Most students have spent the majority of their school career in passive learning environments in which faculty were disseminators of information, and students were required to memorize information or use specified algorithms to "solve problems." In an active learning environment, students are encouraged to engage in the process of building and testing their own mental models from information that they are acquiring. In such a learner-centered environment, faculty become facilitators of learning, and students become active participants, engaging in a dialogue with their colleagues and with the instructor. To create a successful active learning environment, both faculty and students must make adjustments to what has been their respective "traditional" roles in the classroom. For the instructor who is committed to promoting active learning, the challenge lies in helping students understand the necessity of becoming active colleagues in learning. This process can be facilitated if the curriculum includes exercises to direct students' attention to a number of issues that impact their learning. This paper describes four such exercises designed to help students form appropriate course expectations, recognize the need for seeking clarification when communicating, recognize the role of personal experience in building mental models, and become familiar with study aids for building formal models.

    The ability to read, interpret, and evaluate articles in the primary literature are important skills that science majors will use in graduate school and professional life. Because of this, it is important that students are not only exposed to the primary literature in undergraduate education, but also taught how to read and interpret these articles. To achieve this objective, POGIL activities were designed to use the primary literature in a majors biochemistry sequence. Data show that students were able to learn content from the literature without separate activities or lecture. Students also reported an increase in comfort and confidence in approaching the literature as a result of the activities.

  11. Constructing Knowledge

    NASA Astrophysics Data System (ADS)

    Blanton, Patricia

    2003-02-01

    Schools are expected to lay the foundation upon which knowledge can be built and equip students with the tools necessary to accomplish the construction. The role of the teacher in this building process is crucial to the type of structure the student can build. Whether you call it constructivism, discussion teaching, project-based learning, inquiry learning, or any of the other names given to the instructional strategies being suggested by education researchers, the key is getting students to become active participants in the process. While some students may be able to learn from eloquently delivered lectures and dynamic demonstrations, the majority of students cannot effectively retain and apply ideas communicated in this manner.

  12. Relationship between achievement goal constructs and physical self-perceptions in a physical activity setting.

    2004-12-01

    The relations of achievement goal theory constructs and physical self-perceptions were explored with 225 students (91 men, 109 women, and 25 nonindicators; M age=23.5 yr., SD=9.2), enrolled in basic physical activity classes (aerobics, weight training, modern dance, badminton, yoga, tai chi, basketball, racquetball, gymnastics, bowling, aquatone, and step aerobics) in a university setting. Goal orientations (Task and Ego Orientation in Sport Questionnaire), perceptions of the motivational climate (Perceived Motivational Climate in Sport Questionnaire-2), and physical self-perceptions (Physical Self-perception Profile) were assessed. Data were analyzed separately by sex. Ego orientation was the only predictor of Physical Self-perceptions in men, accounting for between 12 and 15% of the variance in Physical Self-worth, Sport Competence, Physical Conditioning, and Body Attractiveness. Constructs of achievement goal theory were not predictive of Physical Self-perceptions in the women. The results are discussed in light of achievement goal theory and the nature of the sample.

  15. Attachment relationships and physical activity motivation of college students.

    PubMed

    Ullrich-French, Sarah; Smith, Alan L; Cox, Anne E

    2011-08-01

    This study was designed to assess the link of attachment relationships with physical activity motivation. Potential mediators of this link were examined in a cross-sectional study targeting college student physical activity motivation and behaviour. Participants completed self-reports of attachment relationships (with mother, father and best friend), self-determined motivation for physical activity, physical activity behaviour and the hypothesised mediator variables of perceived competence, autonomy and relatedness. The results provide support for the mediating role of these variables in the association of father attachment with self-determined motivation. Meaningful variance in self-determined motivation for physical activity and physical activity behaviour was explained. Overall, attachment relationships appear to be relevant, albeit modestly, to physical activity motivation of college students. The findings support continued efforts to integrate attachment and motivational perspectives in the study of college student health behaviour.

    The objectives of this study are to explore the use of asynchronous discussion groups during medical students' clinical rotation in paediatrics. In particular, the impact of role assignment on the level of knowledge construction through social negotiation is studied. Case-based asynchronous discussion groups were introduced to enhance reflection and critical thinking on patient management and treatment, and to offer an exercise in evidence-based medical practice. Groups of approximately 4-5 students were asked to discuss 4 authentic cases during clinical rotation in paediatrics. 49 students interning at the paediatric ward participated in this study. With respect to role assignment, differences between groups (1) with a student or an instructor as moderator and (2) with or without a developer of alternatives for patient management were explored. A content analysis was performed to explore the different levels of social construction of knowledge. The results of multilevel logit analyses show a significant difference in knowledge construction through social negotiation between conditions with a student moderator and conditions where the instructor is moderating, but only when a developer of alternatives is involved. No significant difference was revealed between student-moderated and instructor-moderator groups without a developer of alternatives. It can be concluded that when both the moderator and developer role are assigned to students, their contributions are more likely to reflect a high level of knowledge construction. PMID:16841238

    2011-05-01

    In this paper, we describe and discuss an information and communication technology (ICT)-based intervention designed to improve secondary school students' revision (in contrast to learning) of physics concepts. We show that students' engagement in joint activities via our ICT-based intervention can provide them (and their teachers) with insights into their knowledge base and thought processes, thereby aiding a remedial process we call prescriptive tutoring. Utilising a design-based research methodology, our intervention is currently being implemented and evaluated in a public secondary school in Singapore. Statistical analysis of pre- and post-intervention test scores from the first iteration of our design experiment show that students in the experimental group significantly out-performed students in both the control and alternate intervention groups. In addition, qualitative data obtained from the students from a focus group session, individual interviews and responses to our survey questions reveal that they became more comfortable with the intervention only after they appreciated how the intervention was designed to help them.

    2014-01-01

    Recreational noise exposure and its impact on hearing is a problem to which increasing attention is being paid. In Spanish, it is necessary to have a reliable and valid instrument that is capable of describing the extent of noise exposure. The aim was to create and validate an instrument to determine listening habits and levels of recreational noise exposure in young people. We performed a transversal questionnaire validation study using university students. We assessed the validity of the content and appearance of the "Recreational Hearing Habits Questionnaire" (CHAR in Spanish) through experts' judgment. Then we piloted the administration of semantic adaptation with 30 students. Finally, the instrument was applied to 335 Chilean university students, obtaining with these indicators that demonstrated convergent validity of the construct, criterion and reliability. We used exploratory and confirmatory factor analysis, as well as correlation and agreement tests. It was confirmed that 14 questions in the questionnaire have a good item-test correlation, having also a factorial structure that indicates the existence of three-dimensions. The questionnaire has good internal consistency and convergent validity with the Noise Exposure Questionnaire. In addition, the score obtained in the CHAR is a predictor of the presence of notch at frequencies of 4 kHz in the right ear and 6 kHz in the left. The CHAR is useful for determining listening habits and thereby recreational noise exposure, indicating good psychometric properties.

    When utilizing self-assessments to determine motives for health behaviors, it is essential that the resulting data demonstrate sound psychometric properties. The purpose of this research was to assess the reliability and construct validity of college students' responses to the Reasons for Smoking Scale (RFS). Confirmatory factor analyses and internal consistency reliability coefficients were completed. The data of 110 college students who smoke fell short of providing a good fit, chi2(130) = 343.856, root mean square error of approximation (RMSEA) = 0.123, comparative fit index (CFI) = 0.793, Tucker-Lewis index (TLI) = 0.756. Reliability coefficients ranged from .615 to .912. Three subscales improved reliability by removing an item. Although the fit indices showed improvement with these modifications, good model fit was still not achieved, chi2(50) = 148.059, RMSEA = 0.134, CFI = 0.872, TLI = 0.831. Although other populations' responses to the RFS have demonstrated validity and reliability, this college population's did not. Health educators should use caution when interpreting the results of college students' responses to the RFS because they may be incomplete and/or inaccurate.

    Researchers have gone beyond identity status and been putting more and more emphases on the dynamic process of identity development and its contextual embeddedness. Study of individual's adaptation to the multicultural background is a good point of penetration. Because of the differences in regional conditions and cultural traditions, the minority youths who go to university in the mainstream culture would have special experiences and challenges in the development of their self-identities. Semi-structured interview and narrative were used in this research to discover the characteristics of the self-identity constructing processes of Mongolian undergraduates in a Shanghai university context. Their identity constructing process could be divided into three stages: difference-detecting, self-doubting and self-orienting. The main efforts of identity constructing in each stage could all be described as self-exploring and support-seeking. Special contents of internal explorations and sources of support were distinguished at different stages. As relative results, three main types of self-orientation were revealed: goal-oriented, self-isolated and unreserved assimilated. The characteristics of them are quite similar to those of three identity processing styles proposed by Berzonsky, which indicates there are some common elements lying in all self-development processes of adolescences and young adults. Ethnicity and culture could be background and resource or what Côté called identity capital that impacts the special course of self-identity constructing under similar principles. Different attitudes towards and relationships with their own ethnicity and new surroundings separated the three types of students from each other and interacted with the developmental characteristics and tendencies of their ethnicity identifications and self identities. It was found that minority youths' self-identity constructing was based on their needs of self-value and interacted with their

    Effective engagement of nursing students in the study of biosciences remains a challenge for many tertiary institutes. In this study we attempted to implement and then evaluate a simple hands-on intervention, consisting of a series of hands-on games and puzzles, to increase nursing student engagement with core concepts and anatomical learning involved in clinical anatomy and physiology. The study used a quazi-experimental longitudinal before and after design, to explore the effect of a learning intervention on student performance. Set across three different campuses of the same University, it included 1320 first year undergraduate nursing students from 2013 to 2014 who were studying Anatomy and Physiology. Students were exposed to the interventions or not, and concomitant academic performance, weekly quiz scores, performance in fortnightly worksheets and, across the semester, exam performance were compared. The results show that while the intervention appeared to increase academic performance in students on one campus (2013) compared to the other two, this difference was not sustained into 2014 when a bigger cohort was examined. Despite significant subjective student satisfaction and enthusiasm about these learning and teaching interventions, the data does not support the capacity of these activities to enhance student academic performance. Tertiary entrance scores, being a non-native English speakers and socio-economic status all had a bigger impact on student performance than engagement with fun anatomy and physiology activities.

    Academic results depend strongly on the individual circumstances of students: background, motivation and aptitude. We think that academic activities conducted to increase motivation must be tuned to the special situation of the students. Main goal of this work is analyze the students in the first year of the Degree in Optics and Optometry in the University of Granada and the suitability of an activity designed for those students. Initial data were obtained from a survey inquiring about the reasons to choose this degree, their knowledge of it, and previous academic backgrounds. Results show that: 1) the group is quite heterogeneous, since students have very different background. 2) Reasons to choose the Degree in Optics and Optometry are also very different, and in many cases were selected as a second option. 3) Knowledge and motivations about the Degree are in general quite low. Trying to increase the motivation of the students we designed an academic activity in which we show different topics studied in the Degree. Results show that students that have been involved in this activity are the most motivated and most satisfied with their election of the degree.

  3. How does participation in inquiry-based activities influence gifted students' higher order thinking?

    NASA Astrophysics Data System (ADS)

    Reger, Barbara H.

    Inquiry-based learning is considered a useful technique to strengthen the critical thinking skills of students. The National Science Standards emphasize its use and the complexities and challenge it provides are well suited for meeting the needs of the gifted. While many studies have documented the effectiveness of this type of instruction, there is a lack of research on growth in higher-order thinking through participation in science inquiry. This study investigated such growth among a small group of gifted fifth-grade students. In this study a group of fifth-grade gifted science students completed a series of three forensics inquiry lessons, and documented questions, ideas and reflections as they constructed evidence to solve a crime. From this class of students, one small group was purposely selected to serve as the focus of the study. Using qualitative techniques, the questions and statements students made as they interacted in the activity were analyzed. Videotaped comments and student logs were coded for emerging patterns and also examined for evidence of increased levels of higher-order thinking based on a rubric that was designed using the six levels of Bloom's Taxonomy. Evidence from this study showed marked increase in and deeper levels of higher-order thinking for two of the students. The other boy and girl showed progress using the inquiry activities, but it was not as evident. The social dynamics of the group seemed to hinder one girl's participation during some of the activities. The social interactions played a role in strengthening the exchange of ideas and thinking skills for the others. The teacher had a tremendous influence over the production of higher-level statements by modeling that level of thinking as she questioned the students. Through her practice of answering a question with a question, she gradually solicited more analytical thinking from her students.

  5. The networked student: A design-based research case study of student constructed personal learning environments in a middle school science course

    NASA Astrophysics Data System (ADS)

    Drexler, Wendy

    This design-based research case study applied a networked learning approach to a seventh grade science class at a public school in the southeastern United States. Students adapted emerging Web applications to construct personal learning environments for in-depth scientific inquiry of poisonous and venomous life forms. The personal learning environments constructed used Application Programming Interface (API) widgets to access, organize, and synthesize content from a number of educational Internet resources and social network connections. This study examined the nature of personal learning environments; the processes students go through during construction, and patterns that emerged. The project was documented from both an instructional and student-design perspective. Findings revealed that students applied the processes of: practicing digital responsibility; practicing digital literacy; organizing content; collaborating and socializing; and synthesizing and creating. These processes informed a model of the networked student that will serve as a framework for future instructional designs. A networked learning approach that incorporates these processes into future designs has implications for student learning, teacher roles, professional development, administrative policies, and delivery. This work is significant in that it shifts the focus from technology innovations based on tools to student empowerment based on the processes required to support learning. It affirms the need for greater attention to digital literacy and responsibility in K12 schools as well as consideration for those skills students will need to achieve success in the 21st century. The design-based research case study provides a set of design principles for teachers to follow when facilitating student construction of personal learning environments.

    Earlier research has shown that after physics instruction, many students have difficulties with the force concept, and with constructing free-body diagrams (FBDs). It has been suggested that treating forces as interactions could help students to identify forces as well as to construct the correct FBDs. While there is evidence that identifying interactions helps students in quantitative problem solving, there is no previous research investigating the effect of a visual-representation tool—an interaction diagram (ID)—on students’ ability to identify forces, and to construct the correct FBDs. We present an empirical study conducted in 11 Finnish high schools on students (n=335, aged 16) taking their first, mandatory, introductory physics course. The study design involved groups of students having heavy, light, or no use of IDs. The heavy and light ID groups answered eight pairs of ID and FBD questions in various physical contexts and the no ID group answered two of the eight FBD questions. The results indicate that the heavy ID group outperformed both the light and the no ID groups in identifying forces and constructing the correct FBDs. The analysis of these data indicates that the use of IDs is especially beneficial in identifying forces when constructing FBDs.

  7. Can nursing students' confidence levels increase with repeated simulation activities?

    Cummings, Cynthia L; Connelly, Linda K

    2016-01-01

    In 2014, nursing faculty conducted a study with undergraduate nursing students on their satisfaction, confidence, and educational practice levels, as it related to simulation activities throughout the curriculum. The study was a voluntary survey conducted on junior and senior year nursing students. It consisted of 30 items based on the Student Satisfaction and Self-Confidence in Learning and the Educational Practices Questionnaire (Jeffries, 2012). Mean averages were obtained for each of the 30 items from both groups and were compared using T scores for unpaired means. The results showed that 8 of the items had a 95% confidence level and when combined the items were significant for p <.001. The items identified were those related to self-confidence and active learning. Based on these findings, it can be assumed that repeated simulation experiences can lead to an increase in student confidence and active learning. PMID:26599594

    This reports a history and future prospects of the activities by the Student Forum of the Geoinformation Forum Japan. For growths of academic fields, active communications among students and young scientists are indispensable. Several academic communities in geoinformation fields are established by youths and play important roles of building networks over schools and institutes. The networks are expected to be innovative cooperation after the youths achieve their professions. Although academic communities are getting fixed growth particularly in Japan, youths had gotten little opportunities to make contacts with youths themselves. To promote gotten youth activities among geoinformation fields, in 1998, we started a series of programs that named the Student Forum of the Geoinformation Forum Japan involving students and young scientists within the annual conferences, Geoinformation Forum Japan. The programs have provided opportunities to do presentation their studies by posters, some events, and motivations to create networks among students and young scientists. From 2009, some members of our activities set additional conference in west area of Japan. Thus our activities are spread within Japan. As a result of these achievements, the number of youth dedicating to the programs keeps growing. From 2009, it's getting international gradually, however, almost all the participants are still Japanese. To keep and expand the network, we are planning to make some nodes with some Asian youth organizations in the field of geoinformation. This paper is concluded with proposals and future prospects on the Student Forum of the Geoinformation Forum Japan.

    The present study investigated the guidance provided by science teachers to resolve conflicts during socioscientific issue-based argumentation activities. A graphical representation (GR) was developed as a tool to code and analyze the dialogue interaction process. Through the GR and qualitative analysis, we identified three types of dialogue reconciling strategies. The first one consists of teacher management, in which the teacher temporarily maintains the right to speak when students get mired in an emotional rebuttal situation. The second strategy involves the use of qualifiers to identify the strengths and weaknesses of an opposing argument. The third strategy consists of providing students with guidance to keep both parties (i.e. the students taking, respectively, the affirmative and negative positions) on the same discussion topic and can be used to assist teachers with forming broad questions that prompt students to conduct deeper discussions. These reconciling strategies were beneficial in that they helped students to argue in a more reflective way.

    We discuss the effects of the learning environment of the MIT TEAL project on student cognitive and affective outcomes in introductory electromagnetism. Our assessment included examining student conceptual understanding before and after studying electromagnetism in a media-rich environment. We developed pre-and posttests consisting of conceptual questions from standardized tests, as well as questions designed to assess the effect of visualizations and experiments. The research population consisted of 811 undergraduate students, consisting of small-and a large-scale experimental group and control group. The active learning students improved their conceptual understanding of the subject matter to a significantly higher extent than their control group peers. A subsequent longitudinal study indicates that the long-term effect of the TEAL course on student retention of concepts was significantly stronger than that of the traditional course.

  7. Effect of knowledge integration activities on students' perception of the earth's crust as a cyclic system

    Kali, Yael; Orion, Nir; Eylon, Bat-Sheva

    2003-08-01

    Systems thinking is regarded as a high-order thinking skill required in scientific, technological, and everyday domains. However, little is known about systems thinking in the context of science education. In the current research, students' understanding of the rock cycle system after a learning program was characterized, and the effect of a concluding knowledge integration activity on their systems thinking was studied. Answers to an open-ended test were interpreted using a systems thinking continuum, ranging from a completely static view of the system to an understanding of the system's cyclic nature. A meaningful improvement in students' views of the rock cycle toward the higher side of the systems thinking continuum was found after the knowledge integration activity. Students became more aware of the dynamic and cyclic nature of the rock cycle, and their ability to construct sequences of processes representing material transformation in relatively large chunks significantly improved. Success of the knowledge integration activity stresses the importance of postknowledge acquisition activities, which engage students in a dual process of differentiation of their knowledge and reintegration in a systems context. We suggest including such activities in curricula involving systems-based contents, particularly in earth science, in which systems thinking can bring about environmental literacy.

    Optics and photonics research in Africa has gradually grown in the past ten years with a very active optical community involved in state-of-the-art research. Despite relatively low resources, optics research in the continent is competitive with many international benchmarks and has had a significant impact within the African continent. In the past five years, a group of dynamic students have developed the student chapter network from Tunisia to South Africa. The first student chapters of the optical society of America (OSA) and the international society for optics and photonics (SPIE) were established in South Africa (in the Council for Scientific and Industrial Research (CSIR) and in the University of Stellenbosch), followed by a chapter in Tunisia (Engineering school of communications of Tunis, Sup'Com). In this paper, we will present the major activities of the student chapters of Tunisia and South Africa, and how they are promoting optics and photonics in Africa.

  10. Teacher-student co-construction processes in biology: Strategies for developing mental models in large group discussions

    NASA Astrophysics Data System (ADS)

    Nunez Oviedo, Maria Cecilia

    The aim of this study was to describe co-construction processes in large group discussions. Co-construction, as used here, is a process by which the teacher and the students work together to construct and evaluate mental models of a target concept. Data were collected for an in-depth case study of a single teacher instructing middle school students with an innovative curriculum on human respiration. Data came from transcripts of video taped lessons, drawings, and pre- and post-test scores. Quantitative and qualitative analyses were conducted. In the quantitative analysis, differences in gains between one and two standard deviations in size were found between the pre- and post-test scores indicating that the students increased their understanding about human respiration. In the qualitative analysis, a generative exploratory method followed by a convergent coded method was conducted to examine teacher-student interaction patterns. The aim of this part was to determine how learning occurred by attempting to connect dialogue patterns with underlying cognitive processes. The main outcome of the study is a hypothesized model containing four layers of nested teaching strategies. Listed from large to small time scales these are: the Macro Cycle, the Co-construction Modes, the Micro Cycle, and the Teaching Tactics. The most intensive analysis focused on identifying and articulating the Co-construction Modes---Accretion Mode, Disconfirmation Mode, Modification Mode, Evolution Mode, and Competition Mode---and their relations to the other levels of the model. These modes can either describe the construction and evaluation of individual model elements or of entire models giving a total of ten modes. The frequency of these co-construction modes was then determined by coding, twenty-six hours of transcripts. The most frequent modes were the Accretion Mode and the Disconfirmation Mode. The teacher's and the students' contributions to the co-construction process were also examined

  11. The social construction of communication climate: An analysis of at-risk students in alternative high school

    Souza, Tasha Jean

    1998-12-01

    Alternative high schools affect more potential high school dropouts than any other school or program and are designed to meet the needs of students who have had difficulty in conventional schools. This study examines the communication climate and constructions of caring in an alternative school for at-risk students by using a qualitative analysis grounded in the theoretical perspective of social constructionism. Observations and interviews were conducted over a six month time period. The first two chapters provide a review of literature and a detailed account of the methods used to conduct the study. Chapter Three describes the socially constructed nature of the school and the participants and the dialectical tensions of communication climate revealed from the analysis. The six dialectical tensions of communication climate are: (1) freedom/restraint, (2) disengagement/engagement, (3) personal communication/impersonal communication, (4) disconfirmation/confirmation, (5) equality/inequality, and (6) ambiguity/clarity. Although the school climate is comprised of each of these tensions, the data suggest that the interaction within the majority of classes created some common characteristics of the general communication climate at the school and can be characterized as one of freedom, disengagement, personal communication, disconfirmation, equality, and ambiguity. Chapter Four describes how caring was constructed and communicated. Although some students perceived some teachers as caring about students and about student learning, half of the students interviewed thought they were not learning or not learning much. Finally, Chapter Five provides a summary of the findings and a discussion of the results. The results of this study contribute to an understanding of the social construction of communication climate and caring in general, and within an alternative school for at-risk students, in specific. The results contribute to the understanding of the complexity of the

  16. Understanding and Facilitating Student Bloggers: Towards a Blogging Activity Model

    NASA Astrophysics Data System (ADS)

    Derntl, Michael

    Since instructors have started recognizing the potential of Web 2.0 integration in web-based courses, blogs have been used to provide students with means of virtual communication, contribution, collaboration and community building. In this paper we aim to take another step forward by presenting and analyzing the integration of student blogs in an undergraduate computer science course on software architecture and web technologies: we implemented an LMS extension that acted as a course blog portal by collecting and displaying feeds of externally hosted blogs and logging usage data. Data analysis reveals that students who perform better academically also tend to participate more actively in the course blogosphere. Subsequently, we propose a blogging activity model, which aims to reveal and explain relationships between blogging activity variables—including peer visits, commenting and posting—to achieve a better understanding of lively blog communities in courses.

    With the quick increase of new knowledge in genetics, undergraduate teaching of genetics is becoming a challenge for many teachers. In this paper, the author suggested that it would be important to construct the knowledge network of genetics and to develop the self-learning ability of students. This could help students to read textbooks "from the thicker to the thinner in classroom" and "from the thinner to the thicker outside classroom", so that students would turn to be the talents with new ideas and have more competent ability in biology-related fields.

  19. Describing Changes in Undergraduate Students' Preconceptions of Research Activities

    NASA Astrophysics Data System (ADS)

    Cartrette, David P.; Melroe-Lehrman, Bethany M.

    2012-12-01

    Research has shown that students bring naïve scientific conceptions to learning situations which are often incongruous with accepted scientific explanations. These preconceptions are frequently determined to be misconceptions; consequentially instructors spend time to remedy these beliefs and bring students' understanding of scientific concepts to acceptable levels. It is reasonable to assume that students also maintain preconceptions about the processes of authentic scientific research and its associated activities. This study describes the most commonly held preconceptions of authentic research activities among students with little or no previous research experience. Seventeen undergraduate science majors who participated in a ten week research program discussed, at various times during the program, their preconceptions of research and how these ideas changed as a result of direct participation in authentic research activities. The preconceptions included the belief that authentic research is a solitary activity which most closely resembles the type of activity associated with laboratory courses in the undergraduate curriculum. Participants' views showed slight maturation over the research program; they came to understand that authentic research is a detail-oriented activity which is rarely successfully completed alone. These findings and their implications for the teaching and research communities are discussed in the article.

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

    PubMed

    Carnegie, Jacqueline

    2015-01-01

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

    2014-06-10

    To test the hypothesis that lecturing maximizes learning and course performance, we metaanalyzed 225 studies that reported data on examination scores or failure rates when comparing student performance in undergraduate science, technology, engineering, and mathematics (STEM) courses under traditional lecturing versus active learning. The effect sizes indicate that on average, student performance on examinations and concept inventories increased by 0.47 SDs under active learning (n = 158 studies), and that the odds ratio for failing was 1.95 under traditional lecturing (n = 67 studies). These results indicate that average examination scores improved by about 6% in active learning sections, and that students in classes with traditional lecturing were 1.5 times more likely to fail than were students in classes with active learning. Heterogeneity analyses indicated that both results hold across the STEM disciplines, that active learning increases scores on concept inventories more than on course examinations, and that active learning appears effective across all class sizes--although the greatest effects are in small (n ≤ 50) classes. Trim and fill analyses and fail-safe n calculations suggest that the results are not due to publication bias. The results also appear robust to variation in the methodological rigor of the included studies, based on the quality of controls over student quality and instructor identity. This is the largest and most comprehensive metaanalysis of undergraduate STEM education published to date. The results raise questions about the continued use of traditional lecturing as a control in research studies, and support active learning as the preferred, empirically validated teaching practice in regular classrooms.

    2016-04-01

    Functional materials derived from synthetic helical polymers are attracting increasing interest. Helically substituted polyacetylenes (HSPAs) are especially interesting as typical artificial helical polymers. In recent years, we designed and prepared a series of functional materials based on HSPAs and inorganic materials. The target is to establish some novel hybrid materials that combine the superior properties of both. The examined inorganic materials include silica, graphene, and magnetic Fe3 O4 nanoparticles. Such new functional materials hold great promise and are expected to find practical applications, for instance, as chiral absorbents, chiral sensors, chiral selectors for inducing enantioselective crystallization, chiral catalysts towards asymmetric catalysis, and chiral carriers for enantioselective release. The Personal Account summarizes our major achievements in preparing optically active hybrid materials. We hope it will speed up progress in chiral-related research areas.

    2011-01-01

    This paper aims to discuss the relationships between the selected positive youth development constructs and the enhancement of Hong Kong junior secondary school students' money management skills, values, and attitudes. Various issues of money management of adolescents are reviewed. These issues include the need for money management programs for adolescents, the content and coverage of an appropriate money management program, and its relationships with the selected positive youth development constructs. The curriculum units for secondary 3 students are taken as examples to illustrate the design of the program. It is believed that promoting cognitive competence, self-efficacy, and spirituality could be an effective way to enhance students' money management skills, values, and attitudes, thus preparing them better for facing the finance-related issues in life.

    OBJECTIVE: The current study aimed to validate the construct and reliability of an emotional intelligence scale. METHOD: The Trait Meta-Mood Scale-24 was applied to 349 nursing students. The process included content validation, which involved expert reviews, pilot testing, measurements of reliability using Cronbach's alpha, and factor analysis to corroborate the validity of the theoretical model's construct. RESULTS: Adequate Cronbach coefficients were obtained for all three dimensions, and factor analysis confirmed the scale's dimensions (perception, comprehension, and regulation). CONCLUSION: The Trait Meta-Mood Scale is a reliable and valid tool to measure the emotional intelligence of nursing students. Its use allows for accurate determinations of individuals' abilities to interpret and manage emotions. At the same time, this new construct is of potential importance for measurements in nursing leadership; educational, organizational, and personal improvements; and the establishment of effective relationships with patients.

    Many studies which were published in other countries identified certain benefits and barriers to physical activity among young people. But there is no data about the subject pertaining to Turkish adolescents. This study tries to rectify this with a study of Turkish university students. Undergraduate university students (n = 303) were recruited to the study. Current exercise habits and perceived barriers to physical activity were assessed in the sample. Using a Likert Type scale, participants responded an instrument with 12 items representing barriers to physical activity. Mean scores were computed. External barriers were more important than internal barriers. "Lack of time due to busy lesson schedule", "My parents give academic success priority over exercise. "and "lack of time due to responsibilities related to the family and social environment "were most cited items for physical activity barriers. There is a need for future research, which will be carried out with larger sample groups to develop national standardized instrument. It will be helpful for accurately identify perceived barriers and then recommend changes to enhance physical activity among young people. Key PointsThe purpose of this study was to analyze perceived barriers to physical activity in the university students.The results showed that not having enough time was the most important barrier for not participating in physical activity among our samples.This study with relatively small sample must be considered as pilot study for related studies in the future.

    A novel series of copper(II) and palladium(II) with 4-derivatives benzaldehyde pyrazolone (Ln) were synthesized. The mixed ligand complexes were prepared by using 1,10-phenanthroline (Phen) as second ligand. The structure of these complexes was identified and confirm by elemental analysis, molar conductivity, UV-Vis, IR and 1H NMR spectroscopy and magnetic moment measurements as well as thermal analysis. The ligand behaves as a neutral bidentate ligand through ON donor sites. ESR spectra show the simultaneous presence of a planar trans and a nearly planar cis isomers in the 1:2 ratio for all N,O complexes [Cu(Ln)2]Cl2ṡ2H2O. Schiff bases (Ln) were tested against bacterial species; namely two Gram positive bacteria (Staphylococcus aureus and Bacillus cereus) and two Gram negative bacteria (Escherichia coli and Klebsiella pneumoniae) and fungal species (Aspergillus niger, Fusarium oxysporium, Penicillium italicum and Alternaria alternata). The tested compounds have antibacterial activity against S. aureus, B. cereus and K. pneumoniae.

    2005-06-01

    The importance of attitudes toward science has risen from widely accepted assumptions that achievement and attitude are positively interdependent and that affective variables are as important as cognitive variables in molding student learning. This report examines the effect on student attitudes toward learning chemistry in an active learning environment that has incorporated elements believed to positively influence student attitudes toward science including cooperative learning, hands-on activities, real-world applications, and engaging technology. These elements were considered for synergetic effects and not as individual contributors to the overall results. Two different sections of the same general chemistry course participated. The lecture setting was used as the control. Residualized gain scores were used to compare net changes in student attitudes. Data were analyzed for possible differences in gain for different academic majors. Anxiety in chemistry was monitored for the two class settings in three areas, learning in chemistry, chemistry evaluation, and chemical handling. Qualitative student feedback was also collected and is summarized in this report on the attitudinal aspects of instruction.

    Texts or words/pseudowords are often used as stimuli for human verbal activity research. Our study pays attention to decoding processes of grammatical constructions consisted of two-three words--collocations. Russian and English collocation sets without any narrative were presented to Russian-speaking students with different English language skill. Stimulus material had two types of collocations: paradigmatic and syntagmatic. 30 students (average age--20.4 ± 0.22) took part in the study, they were divided into two equal groups depending on their English language skill (linguists/nonlinguists). During reading brain bioelectrical activity of cortex has been registered from 12 electrodes in alfa-, beta-, theta-bands. Coherent function reflecting cooperation of different cortical areas during reading collocations has been analyzed. Increase of interhemispheric and diagonal connections while reading collocations in different languages in the group of students with low knowledge of foreign language testifies of importance of functional cooperation between the hemispheres. It has been found out that brain bioelectrical activity of students with good foreign language knowledge during reading of all collocation types in Russian and English is characterized by economization of nervous substrate resources compared to nonlinguists. Selective activation of certain cortical areas has also been observed (depending on the grammatical construction type) in nonlinguists group that is probably related to special decoding system which processes presented stimuli. Reading Russian paradigmatic constructions by nonlinguists entailed increase between left cortical areas, reading of English syntagmatic collocations--between right ones.

    Active learning is one of the most efficient mechanisms for learning, according to the psychology of learning. When students act as teachers for other students, the communication is more fluent and knowledge is transferred easier than in a traditional classroom. This teaching method is referred to in the literature as reciprocal peer teaching. In this study, the method is applied to laboratory sessions of a higher education institution course, and the students who act as teachers are referred to as "laboratory monitors." A particular way to select the monitors and its impact in the final marks is proposed. A total of 181 students participated in the experiment, experiences with laboratory monitors are discussed, and methods for motivating and training laboratory monitors and regular students are proposed. The types of laboratory sessions that can be led by classmates are discussed. This work is related to the changes in teaching methods in the Spanish higher education system, prompted by the Bologna Process for the construction of the European Higher Education Area

    Collagen and fibrin are widely used in tissue engineering due to their excellent biocompatibility and bioactivities that support in vivo tissue formation. These two hydrogels naturally present in different wound healing stages with different regulatory effects on cells, and both of them are mechanically weak in the reconstructed hydrogels. We conducted a comparative study by the growth of rat dermal fibroblasts or dermal fibroblasts and epidermal keratinocytes together in collagen and fibrin constructs respectively with and without the reinforcement of electrospun poly(lactic acid) nanofiber mesh. Cell proliferation, gel contraction and elastic modulus of the constructs were measured on the same gels at multiple time points during the 22 day culturing period using multiple non-destructive techniques. The results demonstrated considerably different cellular activities within the two types of constructs. Co-culturing keratinocytes with fibroblasts in the collagen constructs reduced the fibroblast proliferation, collagen contraction and mechanical strength at late culture point regardless of the presence of nanofibers. Co-culturing keratinocytes with fibroblasts in the fibrin constructs promoted fibroblast proliferation but exerted no influence on fibrin contraction and mechanical strength. The presence of nanofibers in the collagen and fibrin constructs played a favorable role on the fibroblast proliferation when keratinocytes were absent. Thus, this study exhibited new evidence of the strong cross-talk between keratinocytes and fibroblasts, which can be used to control fibroblast proliferation and construct contraction. This cross-talk activity is extracellular matrix-dependent in terms of the fibrous network morphology, density and strength. PMID:27349492

    Percentages of correctly imitated grammatical constructions were examined within a framework of reinforcement theory. Four small treatment groups, each of 4 language-delayed children, were repeatedly observed interacting with different student-clinicians. The Therapy Reinforcement Schedule was used to obtain frequency counts of verbal and non-verbal reinforcements so that within each language group the students could be objectively divided into those who frequently and infrequently were reinforcing, and the children into those for whom peer-reinforcement was high or low. The resulting 4 groups were compared for proportions of accurately imitated constructions with a repeated-measures analysis of variance design (student-clinicians' reinforcement x peers' reinforcement x trials). Correctly scored imitations increased significantly over trials. In addition, children interacting with frequently reinforcing students received higher imitation scores than those with infrequently rewarding ones. Significant main effects of reinforcement by the peer group were not observed, although a reliable interaction of student-clinicians' reinforcement x peers' reinforcement was present. Regression analyses indicated the importance of certain types of reinforcements in predicting accuracy of imitation.

    Astronomical Activities for students Motivating students interest in Physical Science through Astronomy Alexis Matthaiou Philekpaideftiki Etaireia, Arsakeio Lyceum Patron, Patras, Greece,(alexiosmat@yahoo.gr) School education aims not only to providing the necessary knowledge to the students but also to inspire and motivate them to realize their special abilities and inclinations and use their potential for making a joyful future for their lives. In this direction we present some activities held in the Arsakeio School of Patras during the years 2005-2008 in the field of Astronomy and Astrophysics, in order to share our experience with the teachers' community. Students from all grades of primary and secondary education participated with enthusiasm. In particular, they observed the Partial Solar Eclipse of October 3rd, 2005,and the Total Solar Eclipse of March 29th, 2006. They took part in observing and registering Solar Spots, using Astronomical equipments like different types of telescopes with filters and solar scopes. Students studied further the nature of Solar Phenomena and their effects on life, participating in the Environmental Program "Sun and Life"(2006-2007). Moreover, students took part in the International Program for measuring the Light Pollution "Globe at Night" (2006-2007) with observing and registering the luminosity of the Orion constellation in the night sky above their residence. Finally, the students participated in the European program "Hands on Universe" (HOU) (2005-2008) working on a project, which was the Greek contribution to HOU, developed from "Philekpaideftiki Etaireia". In particular, they studied the stars' spectrum and acquired information about the stars' life and age of stellar systems, using interactive multimedia technology.

  5. An investigation of the impact of selected prereading activities on student content learning through laboratory activities

    NASA Astrophysics Data System (ADS)

    Kass, Jesse (Shaya)

    This study investigated whether two prereading activities impacted student learning from hands-on science activities. The study was based on constructivist learning theory. Based on the work of Piaget, it was hypothesized that students who activated prior knowledge would learn more from the activities. Based on the work of Vygotsky it was hypothesized that students who talk more and write more would learn more from the activity. The K-W-L chart and anticipation guide strategies were used with eighth grade students at Graves Middle School in Whittier, California before learning about levers and convection currents. D. M. Ogle (1986) created the three-column K-W-L chart to have students activate prior knowledge. In the first column, the students write what they already know about a subject, in the second column, the students write what they want to know about the subject, and the students complete the third column after learning about a subject by writing answers to the questions that they asked in the second column. Duffelmeyer (1994) created the anticipation guide based on Herber's (1978) reasoning guide. In the anticipation guide, the teacher creates three or four sentences that convey the major ideas of the topic and the students either agree or disagree with the statements. After learning about the topic, students revisit their answers and decide if they were correct or incorrect and they must defend their choices. This research used the Solomon (1947) four-square design and compared both the experimental groups to a control group that simply discussed the concepts before completing the activity. The research showed no significant difference between the control group and either of the treatment groups. The reasons for the lack of significant differences are considered. It was hypothesized that since the students were unfamiliar with the prereading activities and did not have much experience with using either writing-to-learn or talking-to-learn strategies, the

    Basic nursing education is governed by individual state rules and regulations lacking in uniformity across the United States and based on unstated and perhaps mistaken assumptions. At the same time, there is increasing evidence of problems and difficulties with the current traditional model of nursing education. Before proposing changes in said model, the authors chose to examine what it is that a nursing student does in a clinical area. The perspective of activities and interactions was chosen to illustrate, through a nonparticipant observation study, the patterns and utilization of time during a scheduled clinical experience for baccalaureate nursing students. The goal of the study was to determine who, other than the client/patient, influences the student learning at the clinical site and how learning time is spent. Two schools (one private and one public) and nine clinical sites with 37 observations were used to collect the data for this study. Findings are best summarized in four (overlapping) categories of school time, registered nurse (RN) staff time, hospital staff time, and supervised time. School time, or time spent interacting with the instructor, another student, and/or the student on his/her own in the practice setting (time exclusive of staff input) constituted 84 per cent of all time. RN staff time that was time spent with either the primary nurse or other RNs on the unit used 10 per cent of the student time, Fourteen per cent of student time was spent in hospital staff time, which includes interactions with any nursing staff or other hospital personnel.(ABSTRACT TRUNCATED AT 250 WORDS)

    Canarsie High School is a typical urban high school in Brooklyn, New York. We have been involved in a District Initiative in collaboration with the City College of New York (CCNY) to initiate and incorporate relevant technologies into the science content areas and classrooms. Through changes in teaching strategies consistent with science education reform movements for mainstream, gifted and special education students; we have been able to effectively motivate student interest and to enhance and enrich the learning potential of all students. Our lessons involve extensive computer and Internet applications, concentrating our efforts in developing high-ordered reasoning skills to address the required concepts covered in Earth Science and Environmental Science curricula. This is a crucial aspect of applied learning approaches as related science concepts are integrated and clearly demonstrated in our daily lives. Our task was to infuse 'live' weather data into Earth Science and Environmental Science classrooms. Student-centered learning activities, laboratory experiences and long-term investigations were designed, written and included into classroom lessons and laboratory sections. This component is aligned with the New Learning and Performance Standards, and makes use of investigative and inquiry-based studies through technological resources. These were accomplished through data readings taken from our school weather station and various World Wide Web sites. Weather data from area "cluster" schools were also used to compare micro-climates within our local region. This fostered peer communication skills among students and staff throughout the Brooklyn High School District.

  15. First year chemical engineering students' conceptions of energy in solution processes: Phenomenographic categories for common knowledge construction

    Ebenezer, Jazlin V.; Fraser, Duncan M.

    2001-09-01

    In this article, we examine first-year chemical engineering students' conceptions of the energy changes taking place in dissolution. Students were individually interviewed with three tasks in which three different salts were dissolved in water, and 17 transcripts were analyzed using a phenomenographic methodology. Four descriptive categories of energy in dissolution were discerned: (a) you give energy (n = 1); (b) water gives energy (n = 17); (c) salt gives off energy (n = 13); and (d) reaction gives off energy (n = 7). Four students gave the same explanation for all three tasks, but more students used the same explanation for two of the tasks: four for Tasks A and B, four for Tasks B and C, and eight for Tasks A and C. Moreover, salt gives off energy was the most common explanation for Tasks A and B (n = 3), reaction gives off energy for Tasks B and C (n = 3), and water gives energy for Tasks A and C (n = 8). Four of the students showed variations of conception within tasks. Students described the solution process of all three tasks using a range of concepts, including previously learned chemical concepts. Even where students used the same chemical concepts in each of the tasks, they did not always give the same meaning to the concepts they used. The phenomenographic categories explanations given by students were used as a basis for developing an approach to teaching energy in solution processes. It is argued that this approach of using phenomenographic categories described at a collective level as a basis for discourse for constructing common knowledge should be used in teaching. It is proposed that a future study must be conducted to develop new trajectories students take to arrive at common knowledge and to understand how to move learners from their personal conceptions to plausible models in solution chemistry within the classroom learning community. Implications for policy are also discussed.

    For large structures such as towers of suspension bridges or cable-stayed bridges, we often need to suppress wind-induced vibration for safety. Especially in the construction stage, the structures have a low tolerance than completed ones. This paper discusses the active vibration dampers used to suppress wind-induced vibration of a tower of a suspension bridge during a construction. The active damper was used to suppress wind-induced vibration in multiple modes predicted by wind-tunnel test. The controller design of the dampers is based on H∞ robust control theory. At each erection step, we measured dynamic properties of towers to adjust parameters of the controller using active vibration exciters. The measured dynamic properties of active controlled structures are compared with those of non-controlled structures. The analysis of free vibration shows the suppression performance of active damper as expected in the controller design.

  3. Hypothetical biotechnology companies: A role-playing student centered activity for undergraduate science students.

    PubMed

    Chuck, Jo-Anne

    2011-01-01

    Science students leaving undergraduate programs are entering the biotechnology industry where they are presented with issues which require integration of science content. Students find this difficult as through-out their studies, most content is limited to a single subdiscipline (e.g., biochemistry, immunology). In addition, students need knowledge of the ethical, economic, and legal frame work in which the industry operates. This article presents an approach to deliver these outcomes in a collaborative and active learning modality which promotes deep learning. In the model, groups of final year undergraduate students form hypothetical biotechnology companies and identify real issues of interest to industry, make integrative team decisions, use professional level technology, and develop appropriate communication skills. The final successful teaching paradigm was based on self reflection, observation, and student feedback to ensure appropriate attainment of content, group work skills and increased confidence in professional decision-making. It is these outcomes which will facilitate life long learning skills, a major outcome applicable for all tertiary education.

Our course redesign consisted of three major elements: 1) reordering the presentation of the course content in an attempt to teach specific content within the context of broad conceptual themes, 2) incorporating active and problem-based learning into every lecture, and 3) adopting strategies to create a more student-centered learning environment. Assessment of our instructional design consisted of a student survey and comparison of final exam performance across 3 years-1 year before our course redesign was implemented (2006) and during two successive years of implementation (2007 and 2008). The course restructuring led to significant improvement of self-reported student engagement and satisfaction and increased academic performance. We discuss the successes and ongoing challenges of our course restructuring and consider issues relevant to institutional change.

  6. Examining the Impact of Student Use of Multiple Modal Representations in Constructing Arguments in Organic Chemistry Laboratory Classes

    NASA Astrophysics Data System (ADS)

    Hand, Brian; Choi, Aeran

    2010-01-01

    This study was designed to examine students’ use of multiple modal representations within their written arguments as a consequence of completing a series of investigations of an organic chemistry laboratory course. One hundred and eleven students from a major Midwestern university were involved in using the Science Writing Heuristic (SWH) approach where they are required to use the argument structure of question, claim, evidence and reflection in completing the written report for their instructor on their laboratory investigations. Results indicate that students who achieved a high score for embedded multiple modal representations in the evidence section also constructed high quality arguments. That is, students who were able to embed multiple modal representations in evidence made strong reasoned connections to support their claim(s) and construct a cohesive argument. Further, there were strong correlations between the laboratory examination score and holistic quality of argument. This study suggests there is a need to build support structures pedagogically for the individual in order to help students understanding the role and function of multiple modal representations in science.

  7. Supporting middle school students' construction of evidence-based arguments: Impact of and student interactions with computer-based argumentation scaffolds

    NASA Astrophysics Data System (ADS)

    Belland, Brian Robert

    Middle school students have difficulty creating evidence-based arguments (EBAs) during problem-based learning (PBL) units due to challenges (a) adequately representing the unit's central problem (Ge & Land, 2004; Liu & Bera, 2005), (b) determining and obtaining the most relevant evidence (Pedersen & Liu, 2002-2003), and (c) synthesizing gathered information to construct a sound argument (Cho & Jonassen, 2002). I designed and developed the Connection Log to support middle school students in this process. This study addressed (1) the Connection Log's impact on (a) argument evaluation ability, and (b) group argument quality and (2) how and why middle school science students used the Connection Log. Four sections of a 7th-grade science class participated. Student groups selected a stakeholder position related to the Human Genome Project (HGP) and needed to decide on and promote a plan to use $3 million to further their position as pertains to the HGP. I randomly assigned one higher-achieving and one lower-achieving class to Connection Log or no Connection Log conditions. Students completed an argument evaluation test, and impact on argument evaluation ability was determined using nested ANOVA. Two graduate students, blind to treatment conditions, rated group arguments, and impact on group argument quality was determined using nested MANOVA. To determine how and why students used the Connection Log, I videotaped and interviewed one small group from each class in the experimental condition. I coded transcripts and generated themes, triangulating the two data sources with informal observations during all class sessions and what students wrote in the Connection Log. I detected no significant differences on claim, evidence, or connection of claim to evidence ratings of debate performances. However, students used the Connection Log to counter different difficulties, and I found a significant main effect of the Connection Log on argument evaluation ability, as well as a

    A chimeric gene construct encoding human peroxiredoxin 6 and Mn-superoxide dismutase from Escherichia coli was developed. Conditions for expression of the fusion protein in E. coli cell were optimized. Fusing of the enzymes into a single polypeptide chain with peroxiredoxin 6 at the N-terminus (PSH) did not affect their activities. On the contrary, the chimeric protein with reverse order of enzymes (SPH) was not obtained in a water-soluble active form. The active chimeric protein (PSH) exhibiting both peroxidase and superoxide dismutase activities was prepared and its physicochemical properties were characterized. PMID:27293100
