数学新课程标准指出,学生的数学学习内容应当是现实的、有意义的、富有挑战性的,这些内容要有利于学生主动地进行观察、实验、猜测、验证、推理与交流等数学活动.数学教学过程不仅是课本知识的传授,更重要的是对学生能力的训练和情操的培养,尤其要重视对学生学习能力和学习方法的培养.抓住典型习题,寻求多种解题途径,促使学生的思维向多层次、多方向发散.注重这种变式模式的教学,对提高学生分析问题和解决问题的能力大有裨益.
The new curriculum standards for mathematics point out that students’ mathematics learning content should be realistic, meaningful, and challenging, and these contents must be conducive to students’ initiative in carrying out mathematical activities such as observation, experimentation, guessing, verification, reasoning, and communication. The teaching process is not only the teaching of textbook knowledge, but also more importantly the training of students’ abilities and the cultivation of their sentiments. In particular, it is necessary to attach importance to the cultivation of students’ learning abilities and learning methods. To grasp typical problems and find a variety of solutions to promote students The thinking is divergent and multi-directional. Paying attention to the teaching of this variant mode will greatly benefit students’ ability to analyze problems and solve problems.
