高中数学灵活多变,方法多样,在平时的例(习)题教学中,常常会碰到一题多解.本来一题多解是培养学生思维灵活性、发散性的重要工具;是提高学生解题能力的重要手段.但如果运用不当,也会造成学生方法混乱、负担加重等不良后果.现结合自己的教学实践,谈谈教学中加强方法横向比较的重要性.一、通过方法的横向比较,训练学生思维的批判性“批判是创新的基石.”有比较就有批判,因此通过方法的横向比较,可以培养学生的批判性思维,深化对各方法的认识,从而提
High school mathematics is flexible and varied, and in the usual case (learning) teaching, often encounter a problem a lot of solutions .It is an important question to cultivate students ’thinking flexibility and divergence .It is to improve students’ But if the improper use, can also cause the students confusion, the heavier burden and other adverse consequences.Currently, combined with their own teaching practice, to talk about the importance of strengthening the horizontal comparison of methods in teaching.One, through the horizontal Comparing and Criticizing Students ’Critical Thinking “Criticism is the cornerstone of innovation.” There is a comparison of criticism, so horizontal comparison of methods can develop students’ critical thinking and deepen their understanding of methods,
