教学是一个复杂的过程,在任何形式的体育课上,体育教师都发挥着有利于学生学习的媒介作用。这些媒介作用包括监测学生的动作,提供适宜的反馈,以及评价学生的动作完成情况。本文将简要地讨论这些媒介作用,并依此提出一个可行的观察策略,从而促进这些媒介作用的相互联系,以及它们在实践中的运用。一、动作监测 Siedentop1983年在对一项研究进行分析之后报告,体育教师通常要占用20-40％的课堂时间来监测学生的行为表现。Siedentop认为,所谓监测,就是在设有任何师生间相互影响的情况下的观察。由于监测占用了大量的时间,因此要明确告诉教师去观察什么。教师需注意的事情很多,如周围的环境是否安 Teaching is a complex process. In any form of physical education, physical education teachers play a medium role in helping students learn. These media functions include monitoring students’ movements, providing appropriate feedback, and assessing the completion of student movements. This article will briefly discuss the role of these media and propose a viable observation strategy based on them to promote the interrelationship between the roles of these media and their application in practice. First, the movement monitoring Siedentop1983 in a research report, sports teachers usually take 20-40% of classroom time to monitor student behavior. According to Siedentop, the so-called monitoring is the observation that there is any interaction between teachers and students. Because monitoring takes a lot of time, it is important to tell the teacher what to observe explicitly. Teachers should pay attention to many things, such as the surrounding environment is safe
