反例教学是初中数学课堂使用较为普遍的一种教学方法,有利于学生对知识点的巩固和深层次的理解。这种教学需要学生和教师共同努力,才能发挥最大的教学效果。一、在初中数学教学中使用反例应注意的问题1.合理地使用反例数学是一门严谨的学科,虽然解决问题的思路多样,但得到的答案是固定的。或者说,一定程度上,数学具有两面性:对或者错。在这种情况下,反例这种教学方法可以发挥很大的作用。在教师使用反
Counterexample teaching is a kind of teaching method that is generally used in junior high school mathematics classroom, which is conducive to students’ consolidation and deep understanding of knowledge points. This teaching requires students and teachers to work together in order to maximize teaching effectiveness. First, the junior high school mathematics teaching should pay attention to the problem of counter-examples 1. The rational use of counter-example mathematics is a rigorous discipline, although the ideas to solve the problem varied, but the answer is fixed. Or, to some extent, mathematics has two sides: right or wrong. In this case, counter-examples of teaching methods can play a big role. In teachers use anti
