From the Court to the Classroom: Opportunities for Engagement,Learning, and Identity in Basketball and Classroom Mathematics

This study explored support for engagement in 2 settings: a high school basketball team and high school mathematics classrooms. Specifically, the study examined 3 aspects of these practices: (a) access to the domain, (b) opportunities to take on integral roles, and (c) opportunities for self-expression in the practice. Drawing on videotape and interview data from 2 African American high school students' participation in basketball and mathematics class, as well as interviews with players' teachers and coaches, this article analyzes how these 3 aspects of practices afforded differential engagement across settings. Findings indicated that the practice of basketball supported deep engagement as players had greater access to an understanding of the domain, were assigned and took up a unique role that was integral to the practice, and had opportunities to express themselves and feel competent. The high school mathematics classroom differentially afforded these opportunities, with 1 student taking them up and the other being unable to, and thus being less engaged. Potential implications of these 3 aspects of the practices for students' practice-linked identities and learning are discussed.     

大学英语课堂教学情感性评价策略研究

通过问卷调查、个别访谈等方式,对大学英语教师在课堂评价中使用情感性评价策略的情况进行调查与分析。结果显示,总体上教师对情感性评价策略观念较强,但是在教学中运用情感性评价策略的频率相对较低,大部分教师已经在有意识地使用积极的、正面的、肯定的课堂评价语。同时分析了成因,并对运用情感性评价策略中存在的问题提出了相应的对策。     

促进学习的评价:在线开放课程中同伴互评投入度研究

后疫情时代,提质增效是在线开放课程内涵式发展的重要抓手。重申促进学习的评价,强调学习者的深度参与,探究学习者参与同伴互评的特点及现存问题具有重要的现实意义。文章基于国内一门在线开放课程,采用学习分析技术从结构化与非结构化数据入手,分析在线开放课程同伴互评过程中学习者的投入度,并进一步探究同伴互评投入度与学习绩效的关系。研究结果表明,在线开放课程中学习者同伴互评的行为投入及认知投入不高,但是参与同伴互评能够识别更有动力通过课程的学习者,且其认知投入度能够预测其学习绩效。基于FBM(学习行为模型)模型提出促进同伴互评投入度的两阶段干预策略,从而提高学习者参与同伴互评的投入度,并为教师及平台提供更具针对性的策略建议。     

Engagement and Termination in the Classroom:

Just as they have significance in shaping the helping relationship, engagement and termination can play a powerful role in the classroom. This paper describes the importance of attending to beginnings and endings both in practice and in teaching, discusses the use of activity based techniques, and specifically focuses on the use of experiential activities to enhance the engagement and termination processes in social work courses. The criteria for selecting, implementing and evaluating activities are reviewed and seven exercises are described in detail, offering instructors the opportunity to examine creative approaches for their own adaptation and use.     

数学课堂阅读教学策略研究

数学阅读教学是终身学习的需要,是信息化、数学化社会的需要,教会学生阅读将提高学生的数学学习效率,有助于个别化学习。数学课堂阅读教学中要阅读与讲解有机结合,采用读前设问、复习旧知、读后设问、运用现代技术等方法与策略,激发学生阅读兴趣、引导学生阅读教科书、教授科学阅读方法。

Epistemological Syncretism in a Biology Classroom: A Case Study

In teaching science, the beliefs of teachers may come into conflict and inhibit the implementation of reformed teaching practice. An experienced biology teacher, Mr. Hobbs, was found to have two different sets of epistemological beliefs while his classroom practice was predominantly teacher-centered. A case study was then performed in order to investigate the underlying issues that contributed to his classroom practice. Data sources included preliminary and follow-up interviews and classroom observations. Data analysis indicated that factors that prevented the epistemological conflict from reaching a resolution included Mr. Hobbs’ beliefs about learning, contextual teaching factors, personal experiences as a student, and views of the nature of science. The findings from this case indicate that science teachers possess complex belief systems that are not immediately obvious to either the teacher or science teacher educators, and science teacher educators need to address teacher beliefs when they encourage teachers to implement reformed teaching practices.     

Peer Perspectives on Teaching: A Case Study in Mathematics

This paper describes an experiment devised to increase our understanding of good teaching practices. Each of two instructors selected a topic and on two consecutive mornings they taught a topic of their choice to a group of 21 experienced and competent tertiary educators but without expertise in the subject area being taught. The organization of the experiment is outlined, and the subject matter selected and strategies adopted by the instructors are described. Outcomes of the experiment are reported in two ways: in terms of general comments provided by the independent evaluator and in terms of the participant's reactions to the exercise. While mathematics teaching was the basis of this study, the peer review process described has general applicability to all disciplines.
