数学归纳法作为解决与自然数有关问题的利器,在中学数学教学中一直被数学教师们所重视,但大多有失偏颇.君不见,各类数学教学书刊中有关数学归纳法的教学论文无不总是论述归纳步如何证明,而奠基步的验证教学很少有文字论及;课堂上,人们也总是把数学归纳法的教学的着力点放在归纳步的 Mathematical induction as a tool to solve problems related to natural numbers has always been valued by mathematics teachers in mathematics teaching in middle schools, but most of them are biased. Not seen, mathematics induction teaching papers in all kinds of mathematics teaching books are always Discuss how inductive step is proved, and there are few written arguments on the verification teaching of the foundational step; In the classroom, people always put the emphasis of mathematics induction teaching on the steps of induction.
