数学归纳法 ,其理解上的难点 ,往往在于第二步的传递性 (或递推性 ) ,因为对于传递性理解上的不到位 ,对于传递性逻辑必要性的认识不够 ,学生极易对数学归纳法的科学性产生怀疑 .笔者认为 ,要进行好数学归纳法的教学 ,就应该十分重视传递性的突破 .在教学中 ,下面一些做法应该?
The difficulty in understanding mathematics induction is often due to the transitivity (or recurrence) of the second step, because the lack of understanding of transitivity and the lack of understanding of the necessity of transitory logic make it very easy for students to study mathematics. The scientificity of induction is skeptical. The author believes that to make a good teaching of mathematics induction, we should attach great importance to the breakthrough of transmissibility. In teaching, what should be done in the following ways?
