习题课是全面完成单元教学任务的继续和延伸,教师要根据教材和学生实际情况,在数学复习课中从典型的问题入手,通过一题多解、一题多变、一题多联,能使学生深入理解概念、定理,掌握解题技巧,有助于促进学生的思维发展,拓宽解题思路,发展学力.一、习题课上的教学案例例1如图1,在△ABC中,已知AB=AC,P为BC边上的任意一点,PE⊥AB于
Exercises is the continuation and extension of the unit teaching tasks to be completed. Teachers should start with the typical problems in the mathematics review class according to the teaching materials and students’ actual situations. So that students in-depth understanding of concepts, theorems, master problem-solving skills, help to promote the development of student thinking, broaden the problem-solving ideas, development of academic ability. Know AB = AC, P is any point on the edge of BC, PE ⊥ AB in
