Özlem Sila Olgun PhD 《The Teacher Educator》2013,48(2):113-125
The main purpose of this study was to investigate the effects of active learning on preservice teachers' dignity, energy, self-management, community, and awareness (DESCA) abilities, attitudes toward teaching, and attitudes toward science. Third year preservice teachers (n = 77) from two different classes were involved in the study. One intact class was assigned as the experimental group, whereas the other intact class was assigned as the comparison group. The comparison group students received the instruction by traditional teaching, and the experimental group received instruction through an active learning paradigm. DESCA abilities and attitudes were measured before and after instruction. Results revealed that there was a significant difference favoring the active learning instruction on preservice teachers' DESCA scores; however, there was no significant difference on preservice teachers' attitudes toward teaching and science. 相似文献

The Validity of the Tritrac-R3D Activity Monitor for the Assessment of Physical Activity in Children
Abstract The purpose of this study was to evaluate the validity of the Tritrac-R3D Activity Monitor, a new instrument designed to improve assessments of physical activity. Comparisons were made with a heart rate monitor and with a Caltrac Activity Monitor. Thirty-five children (ages 9–11 years) were monitored on 3 different school days with all 3 instruments. The Tritrac was moderately correlated with the heart rate monitor (r =.58) and highly correlated with the Caltrac monitor (r =.88). By taking advantage of the minute-by-minute timing capability of the Tritrac and the heart rate monitors, it was discovered, that the correlations between these instruments were highest during free play situations (lunch/recess, recess, after school) and were lower when activity was more limited (class time) or structured (physical education). The ability of the Tritrac to assess activity on a minute-by-minute basis may greatly enhance its overall utility. 相似文献

Abstract The purpose of this paper is to continue the theoretical delineation of the nature of pedagogical content knowledge. Two student teachers were observed teaching an elementary games and high school sport unit and interviewed in depth about their lessons, biography, pedagogical content knowledge, and aspects of the school culture. Data were analyzed by constant comparison and analytic induction. Trustworthiness was established through member checks and triangulation. In the high school, both student teachers tried to use extending and refining tasks, as they had in the elementary school. But, when confronted with aspects of the high school culture, both retreated to a curricular zone of safety relying on application tasks. This zone, the defining aspect of their pedagogical content knowledge of teaching sports, emerged from and was constituted by the relations among goals, capabilities, teaching, inadequate pedagogical content knowledge, and aspects of the school culture. It is argued that situated and cultural orientations contribute to psychological orientations currently used to delineate pedagogical content knowledge. A curricular zone of safety is offered as a concept that helped account for the emergence and persistence of particular ways of knowing content. 相似文献

Abstract The purpose of this study was to examine differences in knowledge representation and problem solutions in expert and novice youth baseball players. Ninety-four players in two age divisions, 7–8 years of age and 9–10 years of age, were assigned to three levels of expertise: high; average; and low skilled. Each subject participated in an interview session to elicit knowledge representation and solutions to five different defensive game situations. Interviews were transcribed and analyzed for content, solution to the problem, errors in problem solution, and qualitative trends. The frequency of advanced solutions to each of the five situations were analyzed in separate chi-square tests for age and expertise. Differences among the levels of expertise were found for the accuracy of solutions to three complex situations. Age was significant for only one situation. Patterns of knowledge content accessed during advanced and less advanced responses indicated both experts and novices were in a beginning stage of developing baseball knowledge structures. Errors in problem solutions indicated children had difficulty monitoring critical conditions and making correct inferences. Players' and teammates' ability to execute baseball skills seemed to influence the content and structure of tactical knowledge accessed during problem solution. 相似文献

Through the determined efforts of MONE, more than one third of the existing 5,851 schools have at least one computer lab.
It is clear that the number of computers in schools in Turkey will continue to increase. 相似文献

Digital learning lives aims to describe a set of practices in school education and beyond that are well developed and based on digital technology. With rich examples from our digital lives, the author shows that digital natives should be able to go beyond spaces and places with which they are familiar. People closely interested in broadening the scope of digital learning and creativity should think of buying this. Gi‐Zen Liu 相似文献

This book seeks to formalise approaches to e‐learning by ensuring that e‐resource design is evaluated and appropriately supported by evidence. The book is aimed at academics who design e‐learning systems and need to devise scholarly evaluation research to assess their success. If this book's likely to relate closely to what you do, I suggest you borrow a copy so you can assess it for yourself. John G Hedberg 相似文献

A content analysis of rap music videos aired on BET, MTV, and VH1 examined the occurrence of controversial themes, gender differences, and skin tone distortion. The results of this study found that current rap music videos have placed an emphasis on themes of materialism and misogyny. Additionally, men and women in the videos differ in their portrayal of these themes. Specifically, female characters are significantly more likely to appear as objects of sexuality. Men and women also differ in their appearance with more African American females appearing to have Eurocentric features. Implications and suggestions for future research are discussed. 相似文献

Thailand's political landscape has changed dramatically during the past five years. The rapid growth of communication technology in Thailand has been instrumental in generating political participation in the national elections of 2001 and 2005. In this article we provide the results of a benchmark study that assesses the early period of this political transformation. Specifically, we examined the use of television and of the Internet for political information by interviewing 500 urban residents. Our results indicate that likely voters actively gathered political knowledge from television advertisements and political party websites. Although use of television and the Internet for political purposes did not increase direct involvement in political parties, it did promote participation in the 2001 national election. Implications of these findings for future research on the use of communication technology for political communication in Asia are discussed. 相似文献
