电子教材:概念、功能与关键技术问题

信息化社会对当前的教材形态带来根本冲击,适合数字一代的电子教材成为未来教材建设的趋势。本文首先界定了电子教材的概念,从呈现、媒体、笔记、作业和管理五个方面提出了电子教材应具有的功能特征;并将电子教材与在线课程的内涵进行了比较;最后,提出电子教材使用的五个关键技术问题,即文档格式、终端设备、内容分发、支持服务环境、安全系统。     

教师表现性评价:概念辨析、结构要素与关键特征

标准化测量的局限性、教师教育与评价的发展困境、对教师专业化问题的日益重视,以及最为核心且根本的——学生学业质量提升对优质师资的呼唤,促使教师表现性评价应运而生,并不断发展.教师表现性评价强调基于明确的标准,使用专业的判断,通过直接观察被评价者的反应表现来评价被评价者在真实情境中的技能运用和问题解决能力,并真实有效地促进学生学习.其结构要素包括表现目标、表现任务和评分规则3个部分.教师表现性评价具有一切行动基于指向促进学生学习的教师专业发展的突出特征,对于解决我国当前教师评价领域的问题具有重要的借鉴意义.     

Key Issues in Sex Education: reflecting on teaching,learning and assessment

Drawing upon critical reflections of staff and student experiences of teaching, learning and assessment on an undergraduate module entitled Key Issues in Sex Education, we discuss the strategies used to engage students in debates around sex and relationships education (SRE). To date, there is little research which evaluates how formal assessments can be made relevant to students' exploration of this subject. In the case of this module, assessment requires students to first deliver a seminar presentation that focuses upon a self-selected issue within the field of sexual politics, policy and practice. Students then submit a manifesto, in the form of posters, leaflets or flyers pitched at relevant stakeholders, and which adheres more to the conventions for political campaigning, rather than the standard essays or examinations commonly used to assess undergraduates. In the light of this, we critically reflect upon student evaluations in respect of this module, address various problems and paradoxes, and offer recommendations for encouraging students to find their own voices when debating complex issues of not only SRE, but also sex, gender and sexualities more widely.

从数据视角透析认知追踪:框架、问题及启示

认知追踪是一种数据驱动的学习者建模技术,被广泛应用于智能导学、智能课堂编排等系统.尤其是2015年深度神经网络被引入认知追踪任务以来,认知追踪成为智能教育领域的研究热点.针对当前研究普遍存在的"重模型、轻数据"以及数据处理不一致等问题,本研究基于近六年国内外35篇有关认知追踪的论文,全面梳理和分析其中被高频使用的数据集,提出以学生、知识、问题三个对象及六类交互关系为核心的认知追踪概念框架,为深层次理解数据内涵和统一数据操作提供指导.本研究还运用该框架对数据集特征进行分类,围绕数据重复、数据顺序、支架题目、技能缺失以及多技能题目等关键问题进行数据一致性分析,特别是针对多技能题目,提出了基于多热编码的表示方法.本研究最后从五方面讨论了认知追踪及未来智能教育的发展趋势:从个体自主学习到多模式混合学习、从单一学习行为到多模态数据融合、从深度学习算法黑箱到可解释分析、从数据驱动到数据与知识联合驱动,以及从技术意识垄断回归教育价值本位,为拓展认知追踪研究边界、促进智能教育创新突破提供参考与指引.     

The Impact of Supply and Demand on Doctorates in Physical Education Teacher Education: The Future of the Profession

ABSTRACT

Quality preparation of doctoral students is a key to the survival of physical education teacher education. Past research has revealed a shortage of students graduating with a doctoral degree in physical education and a general reluctance of teachers to leave their jobs to pursue an advanced degree. As the number of universities preparing new physical education teacher education assistant professors decreases, those in the profession are concerned for the future of teacher education. Unlike other professions that prepare more doctoral students than the market can accommodate, this is not the case for physical education teacher education doctoral programs. This article will provide summary information on supply and demand, which will be used to identify trends and recommendations for the future. This article will explore the status of doctoral programs in the United States and whether university programs will be able to prepare a sufficient number of professors to replace the aging physical education teacher education professoriate.
