复习是教学中的一个重要环节。在现在的科学课中,复习课存在教法单一,枯燥无味;简单重复,停留在表面;学生主体地位缺失;重点不突出,难点不能突破等诸多问题。要上好复习课,提高复习课的有效性,必须充分了解教学内容和学生实际情况,写好复习课教案;优化教学策略,凸现学生主体地位;创设有趣的教学情境,吸引学生的兴趣;搭建知识网络,尽量做到旧课新上;巧设概念的对比与辨析;精心设计练习,巩固知识,提升能力。复习时,要把学生已有的知识和经验作为教学的出发点,把巩固提升能力作为教学的落脚点,使复习收到良好的效果。
Review is an important part of teaching. In the current science class, the review class exists a single teaching, boring; simple repetition, stay on the surface; lack of the main body of the student status; focus is not prominent, the difficulties can not be broken and many other issues. To make a good review of class and improve the effectiveness of the review class, we must fully understand the teaching content and the actual situation of students, write lesson plans for reviewing classes, optimize teaching strategies and highlight student’s dominant position, create interesting teaching situations to attract students’ interest, and build Knowledge network, as far as possible to make the old class new; clever concept of contrast and discrimination; well-designed exercises, consolidate knowledge and enhance ability. When reviewing, we should regard the students’ existing knowledge and experience as the starting point for teaching and regard consolidating and enhancing their ability as the end point of teaching so that the review can receive good results.
