寻求对典型例题的多思路分析,不仅能使学生巩固知识、活用知识、激发兴趣,而且能培养学生思维能力和创造能力.笔者在数学教学的实践中,长期坚持多思路分析典型例题来拓宽学生视野,发挥他们的主观能动性,收效不错,下面举例说明: 题目:已知如图1,D是AC边上一点,E、F分别是AD、BC的中点,直线EF交BA的延长线于M,且AM=AE,求证:AB=CD.
Looking for a multi-truth analysis of typical examples can not only enable students to consolidate knowledge, use knowledge, stimulate interest, but also develop students’ thinking ability and creative ability. In the practice of mathematics teaching, the author persists in multi-path analysis of typical examples to broaden students’ Vision, play their subjective initiative, have good results, the following examples illustrate: Title: Known as Figure 1, D is a point on the AC side, E, F are the midpoints of AD, BC, straight line EF to the BA extension line M, and AM = AE, verification: AB = CD.
