在例题教学中,很多学生因对问题的分析求解浅尝辄止,且未能及时去归纳、总结解决有关数学问题的本质规律和通性通法,使得学习收效甚微.怎样使学生摆脱这种困境呢?数学教育家波利亚说过:数学问题的解决仅仅只是一半,更重要的是回顾和反思.实践表明:在例题教学中,教师经常引导学生积极地反思自己的解题活动,并逐渐地使这种反思成为其一种较为自觉的意识和习惯,可帮助其较快提升解题能力,从而使例题教学更有效.
In the teaching of examples, many students try their best to analyze and solve problems, and fail to summarize them in time, and conclude that solving the essential laws and general methods of mathematical problems makes learning ineffective. Mathematical educator Polia said that the solution to the problem of mathematics is only half, more importantly is to review and reflect.Practice shows that in the example teaching, teachers often guide students to actively reflect on their problem-solving activities, and gradually To make such a reflection of a more conscious awareness and habits, can help them improve their ability to solve problems, so that the teaching of examples is more effective.
