怎样既能减轻学生的课业负担、又能大幅度提高复习效果,一直是高中数学教学亟待解决的重要课题。近年来,笔者通过反复探究,逐步形成了一种行之有效的复习方法——“四环式”复习法,即每节复习课,师生共同实施“预习、讲课、复习、作业”四个操作程序。1预习:注重目标性及实施方法预习是复习课四个环节中的第一环。它的目的是:为上复习课作准备,扫清后续讲课的障碍。同时,教师也可以从预习中了解到学生的知识水平,从而编拟针对性强的教案和练习题。
How to not only reduce the students’ academic burden, but also greatly improve the effectiveness of the review, has always been an important issue to be solved in high school mathematics teaching. In recent years, through repeated inquiry, the author has gradually formed an effective review method - the “four-ring” reviewing method, that is, each review class, teachers and students jointly implement the “preview, lectures, review, homework ”Four operating procedures. 1 Preview: Focus on the objectives and implementation methods Preview is the first of four links in the review class. Its purpose is: to prepare for the review class, clear the obstacles to follow-up lecture. At the same time, teachers can also learn from the preview of the students knowledge level, so as to prepare targeted lesson plans and exercises.
