为了更好地激发中学生的数学兴趣 ,教学中应注意培养学生的求异思维 .在教学活动中 ,求异思维表现在两方面 :一是一题多解 ,让一个数学问题展现尽可能多的求解方法 ;二是对给定条件的证明题能清晰联想起它可能推导的结论 ,达到一题多证的效果 . In order to arouse the interest of middle school students better in mathematics, teaching should pay attention to cultivating students’ different thinking.In the teaching activities, the thinking of different thinking is manifested in two aspects: one is multi-solution of one question, and one mathematical problem is exposed as much as possible Solution method; the second is the proof of the given conditions can be clearly remembered the conclusions it may be derived to achieve a multi-card effect.
