“板演”是适应教学需要,让学生在黑板上或教师发给学生的小黑板上,演算练习题的一种经常使用的课堂练习形式。从某种意义上说,教学过程是教与学的信息传递过程,而学生板演是教学反馈的一种重要形式。在小学数学课堂教学中,无论是新授课、练习课,还是复习课,一般都安排有学生板演的环节。因此,在教学中正确地运用板演手段,是教学中一个值得注意的问题。 一、学生板演在课堂教学中的作用 学生板演一般安排在以下几个教学环节。一是在基本训练时让学生板演,目的是了解学生对以前学过的知识掌握的程度,为新授课搭桥铺路;二是在进行新授课时,让学生板演。如,在自学课本的基础上板演尝试题,从中可看出学生理解新知识的情况,使教师能有的放矢地进行教学;三是在做“巩固练习”时让学生板演,目的在于了解学生对当堂所学知识的理解和简单运用的情况。 On the blackboard or on the small blackboard that the teacher sends to the student, “board play” is a form of classroom exercise that is frequently used in calculus exercises to suit the teaching needs. In a sense, the teaching process is the process of information transmission between teaching and learning, and the student boarding is an important form of teaching feedback. In primary school mathematics classroom teaching, whether it is a new lecture, practice class, or review class, usually arranged for a part of the students board. Therefore, the correct use of boarding in teaching means is a noteworthy problem in teaching. First, the role of student boarding in classroom teaching Students play generally arranged in the following aspects of teaching. The first is to let the students perform in basic training. The purpose is to understand the degree to which students have mastered the knowledge they have previously learned and pave the way for new teaching. Second, let the students perform in a new lecture. For example, on the basis of self-study textbooks on board performance questions, we can see that students understand the new knowledge, so that teachers can be targeted for teaching; third is to do “consolidation exercises” for students to perform, the purpose is to understand the students The understanding of the school knowledge and simple use of the situation.
