The purpose of this study was to examine (a) the effects of three curricular activities on students'situational motivation (intrinsic motivation [IM], identified regulation [IR], external regulation, and amotivation [AM]) and physical activity (PA) levels, and (b) the predictive strength of situational motivation to PA levels. Four hundred twelve students in grades 7-9 participated in three activities (cardiovascular fitness, ultimate football, and Dance Dance Revolution [DDR]) in physical education. ActiGraph GT1M accelerometers were used to measure students' PA levels for three classes for each activity. Students also completed a Situational Motivation Scale (Guay, Vallerand, & Blanchard, 2000) at the end of each class. Multivariate analysis of variance revealed that students spent significantly higher percentages of time in moderate-to-vigorous PA (MVPA) in fitness and football classes than they did in DDR class. Students reported higher lM and IR toward fitness than DDR They also scored higher in IR toward fitness than football. In contrast, students displayed significantly lower AM toward fitness than football and DDR Hierarchical Linear Modeling revealed that IM was the only positive predictor for time in MVPA (p = .02), whereas AM was the negative predictor (p < .01). The findings are discussed in regard to the implications for educational practice.  相似文献

Abstract

This exploratory study determined if the responses of male varsity basketball players to six factors influencing cohesion were a function of level of competitive intensity and/or the importance of the players to their team. Players on intact teams from five levels of competition – elementary school, junior high school, senior high school, small college and large college–responded to a cohesion questionnaire at the end of the season. Coaches designated five players with the most game playing time as “starters” and five players with the least game playing time as “reserves.” A team factor score for Team Performance Satisfaction, Self Performance Satisfaction, Task Cohesion, Affiliation Cohesion, Desire for Recognition and Value of Membership was calculated. Each team factor score served as the dependent variable in a 2 (player status) × 5 (level of competition) analysis ofcovariance design, with teams nested in the second factor. The won-loss record served as the covariate. Results indicated that “starters” were more satisfied with their own performance, were more task conscious, had a greater affiliation desire, and valued their membership on the team to a greater degree than the “reserves.” The elementary and junior high school team members were significantly more satisfied with the team's performance, were more satisfied with their own self performance, were more affiliation conscious, and valued their team membership to a greater degree than did college team members. The interaction between player status and level of competition was not significant for any of the factor scores.  相似文献

Online higher education institutions are presented with the concern of how to obtain valid results when administering student learning outcomes (SLO) assessments remotely. Traditionally, there has been a great reliance on unproctored Internet test administration (UIT) due to increased flexibility and reduced costs; however, a number of validity concerns have led some researchers to question its implementation and results. To mitigate the limitations of UIT, a relatively new approach, referred to as online proctoring, has been developed to mirror in-person proctoring remotely by capitalizing on technology to create verifiable and secure testing conditions. This study evaluated the comparability of online proctored and unproctored test administration in a low-stakes testing context on user-friendliness, examinee behavior, and mean scores. Results demonstrated improved user-friendliness (e.g., ease of logging in); however, no significant differences were observed in terms of keystroke information, rapid guessing, or aggregated scores between proctoring conditions. Overall, these results suggest that online institutions can implement UIT, which is a cost-effective approach to test administration, and obtain valid group-level inferences from SLO assessments.  相似文献

This article introduces a research study on student model formation and development in introductory mechanics. As a point of entry, I present a detailed analysis of the Long Decay Model of one-dimensional projectile motion. This model has been articulated by Galileo (in De Motu) and by contemporary students. Implications for instruction are discussed.

The emergence of social media has radically transformed the way we create and consume information. These changes have in turn given rise to new models of librarianship centered on principles of participation, interaction, and collaboration. Over the last decade, academic libraries have eagerly adopted social media as a means of enhancing services and connecting with a new generation of users. But how exactly has this technology changed libraries? In what ways has the social web transformed library services or our relationships with users? This article attempts to assess the impact of social media on academic libraries in the United States through a review of the literature published since 2005. In particular, it looks at how academic libraries have used social media to improve or develop new services. By comparing published case studies with the theoretical literature, this article seeks to separate theory from practice and determine the extent to which the social web has transformed library practice. The author concludes that, despite several noteworthy examples, the majority of social library applications ultimately fail to live up to the transformative potential promised within the literature and that this failure may have more to do with philosophical rather than technical limitations.  相似文献

ABSTRACT

Using the notion of structure of feeling by Raymond Williams, this article seeks to illuminate an ideological understanding of Korean English teachers’ anxiety and deep sense of insecurity in English language teaching (ELT). Through a discussion of how their anxiety is grounded deeply within unequal social relations and how they reframe their anxiety through critical reflection on the cultural and ideological bias of their own anxiety, it points out the intricate relationship between ideology and emotion; teachers’ emotions are shaped by dominant ideologies that constitute the social structures constraining their position as teachers, while their engagement with those emotions also enables their self-transformation towards gaining confidence as teachers. The results of the study emphasise the tension between social structure and agency in teachers’ emotional experiences and discuss implications for teacher education and development.  相似文献

Conclusion To educate teachers who have adequate content knowledge, possess the necessary skills to implement effective teaching strategies, and are confident and have positive attitudes toward science and the teaching of science, alternative teaching models are necessary. The University of Wyoming model provides such an alternative. Based on observations and interviews of students and the mentor teachers, it is apparent that it has created a very positive response in prospective teachers who have participated in it. The Wyoming model provided an effective process to train future elementary teachers. Even though it focused on science, the basis is general enough that it could be successfully extended to other disciplines with only minor modifications; however, all of the major components of the Wyoming model are vital to its success. Content courses designed specifically for prospective teachers have been successful in giving the students the content knowledge and providing opportunities for effective modeling. The seminars provide strong mechanisms to connect content to methodology and make the content relevant to teaching and to children. Because of their modeling, peer coaching, and sharing their time and students, the mentor teachers are essential partners in helping the university educate future teachers. Finally, the cooperation of all partners—district administrators, teachers, science content and science education university faculty, and students—is necessary to provide early and continuous experiences to prospective teachers. This material is based upon work supported in part by a grant from the National Science Foundation (Grant No. TTE-8851105). Any opinions, findings, conclusions, and/or recommendations expressed in this article are those of the authors and do not necessarily reflect those of the NSF.  相似文献

Foundational issues in evolution education   总被引:1,自引:0,他引:1  
There is a great need for effective evolution education. This paper reviews some of the evidence that demonstrates that need and analyzes some of the foundational semantic, epistemological, and philosophical issues involved. This analysis is used to provide a functional understanding of the distinction between science and non-science. Special emphasis is placed the scientific meaning of the terms theory, hypothesis, fact, proof, evidence, and truth, focusing on the difference between religious belief and acceptance of a scientific theory. Science is viewed as theologically neutral and as not mutually exclusive from religion. Finally, a number of practical recommendations to the classroom biology teacher are presented.  相似文献
