体育强国建设下幼儿家庭体育的现象学研究     

白翠瑾  李哲  杨光 《沈阳体育学院学报》2020,(2):34-40

2019年是中国体育划时代的一年,以《体育强国建设纲要》的颁布为起点开启了体育事业的全新征程。幼儿家庭体育是学前教育的薄弱环节,父母的体育引导是家庭体育的重中之重。采用现象学方法,以幼儿父母访谈为抓手诠释幼儿家庭体育现象。结果认为:父母观念下幼儿家庭体育的掣肘包括主观因素的理念束缚、安全焦虑、指导孱弱、精力局限,客观因素的经济无力、规划无序、保障无依。针对存在障碍提出化解路径:通过革新理念调解传统意识的偏颇,通过制定指南消解育教于体的困惑,通过家园共育缓解精力、经济的压力,通过社会支持纾解供需之间的失衡。  相似文献   

Reducing the prior-knowledge achievement gap by using technology-assisted guided learning in an undergraduate chemistry course     

Anna J. Lou  Susanne M. Jaeggi 《科学教学研究杂志》2020,57(3):368-392

There have been many practical obstacles for teachers to implement evidence-based educational technology, especially in STEM classrooms. By implementing learning principles related to Cognitive Load Theory, we developed an innovative Technology-Assisted Guided Learning (TAGL) approach and its web-based instructional tool, combining expertise from educational research and best teaching practices to enhance guided student-centered learning in chemistry. A total of 185 community college students were randomly assigned to learn stoichiometry through either TAGL or one of two active control interventions, traditional direct instruction and Khan Academy, a widely used web learning platform. We found that the TAGL group significantly outperformed both active control groups immediately after instruction, and furthermore, despite the fact that all groups received additional instruction in stoichiometry, the beneficial effects of TAGL compared to the control groups were maintained a month later. Notably, TAGL was able to eliminate the achievement gap between students with low prior knowledge and students with high prior knowledge. Furthermore, prior-knowledge activation was found to be especially beneficial for students with low prior knowledge. Our work contributes to existing research in learning theories and provides new insight toward the development of more effective and adaptive instructional designs. By translating research into practice, this study demonstrates the great potential of using innovative computer-based technology to improve student learning for all.  相似文献

我国中学体育研究的知识图谱分析     

杨忠英 《体育科技文献通报》2020,(5):153-155,158

为给中学体育的进一步研究和发展提供参考,本文采用可视化分析法、文献资料法、数理统计法等研究方法,以2019年以前在核心期刊和CSSCI期刊上发表的有关中学体育研究的论文为研究对象,运用Cite Space V可视化分析软件绘制出关于中学体育研究的知识图谱并进行分析和解读。结果表明:(1)我国中学体育研究领域的论文发文量整体上呈现出不规则的倒"V"字型;(2)我国中学体育研究领域的学者合作不够密切,大部分学者处于各自为战的状态;(3)我国中学体育研究领域科研机构之间松散的合作局面不利于该领域的发展;(4)中学体育领域的研究由集中化向多元化方向发展,且该领域的研究热点大多分布在中学体育的主体、中学体育教学、不同地区的中学体育、中学体育的发展4个方面。  相似文献   

Professional knowledge or motivation? Investigating the role of teachers’ expertise on the quality of technology-enhanced lesson plans     

《Learning and Instruction》2020

In an expertise study with 94 mathematics teachers varying in their relative teacher expertise (i.e., student teachers, trainee teachers, in-service teachers), we examined effects of teachers' professional knowledge and motivational beliefs on their ability to integrate technology within a lesson plan scenario. Therefore, we assessed teachers' professional knowledge (i.e., content knowledge, pedagogical content knowledge, technological knowledge), and their motivational beliefs (i.e., self-efficacy, utility-value). Furthermore, teachers were asked to develop a lesson plan for introducing the Pythagorean theorem to secondary students. Lesson plans by advanced teachers (i.e., trainee teachers, in-service teachers) comprised higher levels of instructional quality and technology exploitation than the ones of novice teachers (i.e., pre-service teachers). The effect of expertise was mediated by teachers' perceived utility-value of educational technology, but not by their professional knowledge. These findings suggest that teachers’ motivational beliefs play a crucial role for effectively applying technology in mathematics instruction.  相似文献   

Instructional design for single information literacy sessions     

Elizabeth L. Black 《Public Services Quarterly》2020,16(3):161-171

Abstract

The purpose of this paper is to describe how the Understanding by Design instructional design framework can be applied to design high-quality single-session information literacy instruction. The author describes the Understanding by Design process in detail, noting modifications for single instructional session design with examples from the application of this instructional design process to design co-curricular instruction sessions for undergraduates.  相似文献   

Confidence in prior knowledge,self-efficacy,interest and prior knowledge: Influences on conceptual change     

《Contemporary educational psychology》2014,39(2):164-174

This study explored how confidence in prior knowledge, self-efficacy, interest, and prior knowledge interact in conceptual change learning. One hundred and sixteen college students completed an assessment of confidence in prior knowledge, self-efficacy, interest, prior scientific understanding, and prior misconceptions before reading a refutation text on seasonal change. Students’ misconceptions and scientific understanding of seasonal change was then assessed before and after reading a refutation text, and again at a two week delayed posttest. Three profiles of students emerged based on their confidence in prior knowledge, self-efficacy, interest, prior scientific understanding, and prior misconceptions. The profiles included: (1) Low (low confidence, self-efficacy, interest, and prior scientific understanding and high prior misconceptions), (2) mixed (high confidence, self-efficacy, and interest, but low prior scientific understanding and high prior misconceptions), and (3) high (high confidence, self-efficacy, interest, and prior scientific understanding and low prior misconceptions). Results indicated that the mixed profile appeared to be most productive for conceptual change and that learner characteristics most productive for conceptual change learning may differ from those most productive in other learning situations.  相似文献
