Primary science education is a concern around the world and quality mentoring within schools can develop pre‐service teachers' practices. A five‐factor model for mentoring has been identified, namely, personal attributes, system requirements, pedagogical knowledge, modelling, and feedback. Final‐year pre‐service teachers (mentees, n = 211) from three Turkish universities were administered a previously validated instrument to gather perceptions of their mentoring in primary science teaching. ANOVA indicated that each of these five factors was statistically significant (p<.001) with mean scale scores ranging from 3.36 to 4.12. Although mentees perceived their mentors to provide evaluation feedback (95%), model classroom management (88%), guide their preparation (96%), and outline the science curriculum (92%), the majority of mentors were perceived not to assist their mentees in 10 of the 34 survey items. Professional development programmes that target the specific needs of these mentors may further enhance mentoring practices for advancing primary science teaching.  相似文献

There is a large body of research that has explored students’ misconceptions about science phenomena. Less research, however, has been devoted to identifying teachers’ misconceptions, but the results of the few existing studies demonstrate that teachers and students possess similar misconceptions. This study explored the physical science conceptions of 103 elementary science teachers to determine whether, after three decades of misconception research, teachers still possess conceptions similar to those held by students. We found that our teachers expressed misconceptions regarding gravity, magnetism, gases, and temperature that were similar to common student misconceptions. Suggestions for improving science professional development programs are discussed.  相似文献

Abstract

This study was designed to examine the use of selected biomechanical variables in the prediction of basketball skill. The subjects were college women in three mutually exclusive groups of basketball skill: an elite group of six competitors on the United States team in the World University Games, a good group of seven players on a varsity team, and a poor group of nine members of an instructional class. An accuracy test and digitized film records provided the data for 12 variables related to the process or product of free throw shooting. Discriminant analysis was employed to predict the categorical variable of skill. The most discrimination came from variables of accuracy, stability, and height of release rather than from variables of projection. Poor shooters were distinguished by instability; elite shooters were characterized by a high point of release and accuracy under pressure. Depending on the method of prediction, rates for correct classification of subjects ranged from 76–100%. Thus, it appears that discriminant analysis using biomechanical variables can be a successful tool in the prediction of basketball skill.  相似文献

Abstract

The purpose of this study was to examine the development of skill competence and tactical sophistication during a games unit conducted following the features of sport education provided by Siedentop (1994). One team of six players was followed through a 30-lesson season of “Ultimate.” Using Gréhaigne, Godbout, and Bouthier's (1997) formula for an efficiency index, together with a number of other measures of skill and tactical competence, it was determined that these students made significant improvements in selection and execution dimensions of the game. Furthermore, lower skilled students did not feel marginalized within their teams and believed they had equal opportunities for improvement. The key reasons for developing competence in this setting were the sufficient length of the season to allow for significant practice opportunities and the consistent team membership throughout season, which allowed all players to develop a sense of usefulness. This curriculum model provides one way students can develop skills through a system of game playing, provided sport education units are structured to prevent the more skillful players from dominating the games.  相似文献

This paper reports on a study that aims to address the challenges of UN Sustainable Development Goal 4 to ensure inclusive and equitable quality education for all. The study focuses on school mathematics in particular. With regard to ensuring equitable access to quality education, it is argued that there is a need to consider the epistemic quality of what students come to know, make sense of and be able to do in school mathematics. Accordingly, the aim is to maximize the chances that all pupils will have epistemic access to school mathematics of high epistemic quality. The study is based on the theoretical framework of Joint Action Theory in Didactics (JATD). Associated research questions focus on the quality of teacher-student(s) joint action and on the epistemic quality of the content. The paper draws on empirical research findings of the Developing Mathematical Thinking in the Primary Classroom (DMTPC) project (2010–12) and also on the findings of a parallel study of mathematics teachers’ assessment practices in Ghana. One teacher’s action research project is used as an exemplar to illustrate how mathematics can become more accessible and inclusive thus leading to an evolution in mathematical thinking and high-quality epistemic access for all.  相似文献

In this paper we discuss the background to this study in the development of the international MSc e‐Learning Multimedia and Consultancy. The aims of the study focus on the conditions for achieving communication, interaction and collaboration in open and flexible e‐learning environments. We present our theoretical framework that has informed the design of programme as a whole which is based on a socio‐constructivist perspective on learning. Our research is placed within an action research framework and we outline our position within the critical or emancipatory tradition and also our standpoint on the use of ICT in education. We discuss the design of the programme and also our pedagogical approach and describe in detail the particular context for this study. We report on the student experience of being learners on this module, their perceptions of what they have gained most from learning from and with each other and their responses to the various ways in which ‘scaffolding’ has been designed and implemented by the tutors. Finally we offer some reflections on the conditions for achieving well‐orchestrated interdependence in open and flexible e‐learning environments.  相似文献

The present study set out to examine the role played by preschool children's intellectual and behavioural characteristics in their parents’ expectations for school performance. Preschool children who were expected by their parents to attend university were compared with those who were expected to leave school at the earliest opportunity. Children whose parents had lower expectations came from lower social classes and tended to be boys. The two groups differed in a number of other ways. The high expectations group tended to be more intelligent and less overactive. When the associations between expectations, sex and SES were controlled for, these differences persisted. The findings show that there is already an association between high educational expectations and educational advantage before children enter school. Educationalists should be cautious when developing policy on the basis of the assumption that the reported association between parental expectations and school achievement reflects the impact of expectations rather than the persistence of early acquired competence.  相似文献

This paper reports on some findings from the first year of a three-year longitudinal study, in which seventh- to ninth-graders were introduced to engineering education. Specifically, the paper addresses students’ responses to an initial design activity involving bridge construction, which was implemented at the end of seventh grade. This paper also addresses how students created their bridge designs and applied these in their bridge constructions; their reflections on their designs; their reflections on why the bridge failed to support increased weights during the testing process; and their suggestions on ways in which they would improve their bridge designs. The present findings include identification of six, increasingly sophisticated levels of illustrated bridge designs, with designs improving between the classroom and homework activities of two focus groups of students. Students’ responses to the classroom activity revealed a number of iterative design processes, where the problem goals, including constraints, served as monitoring factors for students’ generation of ideas, design thinking and construction of an effective bridge.  相似文献
