摘要:该文从教学需求出发,设计一套具有权重的随机点名课堂提问系统,其目的是提高课堂教学质量与学生参与的积极性。该系统具有两个方面的功能,第一,可以避免教师在课堂教学中的带有个人感情色彩的提问偏重,给予每个学生相对均等的回答课堂提问的机会;第二,可以根据学生知识掌握情况以及课堂问题难易程度,适度调节随机点名的权重分配,提高学生问题回答质量与课堂效率,将课堂提问在教学环节中发挥到最大的作用。

Abstract: Based on the needs of teaching, this paper designs a set of weighted and random classroom questioning systems, the purpose of which is to improve the quality of classroom teaching and the enthusiasm of student participation. The system has two functions. First, it can avoid teachers 'personal emotional questions in classroom teaching, giving each student a relatively equal opportunity to answer classroom questions; second: according to the students' basic knowledge Grasp the situation and the difficulty of classroom questions, moderately adjust the weight distribution of random roll calls, improve the quality of students' question answering and classroom efficiency, and maximize the role of classroom questioning in teaching. Keywords: random roll call random check roll weighting algorithm classroom questioning.
Key words: random roll call; spot check roll call; weighted algorithm; weight distribution ; classroom questioning
1 引言
傳统的课堂提问点名主要有两种方式,第一种是老师根据学生名单顺序依次进行点名提问,第二种是随机提问。这两种方法对课堂教学效果的帮助作用都不是特别理想:在第一种方法中,已经被点名并且回答问题的学生,可能出现懈怠听讲的学习状态[1],课堂提问不能很好地起到督促学习的效果;在第二种方法中,老师进行随机提问,则具有主观性与偏向性,学生很难获得均等的回答问题机会,使整体的教学质量的提升受到限制[2]。本设计将克服传统的课堂提问点名形式存在的弊端,引入了加权随机[3]机制,系统记录学生以往回答问题的情况,作为其基础知识掌握情况的反馈,来预测其学习掌握程度,并且结合课堂问题……
