初中数学《新课程标准》指出:有效的数学学习过程不能单纯地依赖模仿与记忆,教师要引导学生主动地从事观察、实验、猜测、验证、推理与交流等教学活动,从而使学生形成自己对数学知识的理解和有效的学习策略。因此,教师要根据具体的学习内容,结合学生的知识水平,创设有利于学生进行探究研讨的问题情境,使学生在自主探索与合作交流中掌握探究的方法,体验探究的乐趣。教 The junior high school mathematics “New Curriculum Standard” points out that the effective mathematics learning process can not rely solely on imitation and memory. Teachers should guide students to take the initiative to engage in teaching activities such as observation, experiment, speculation, verification, reasoning and communication so that students can form their own Understanding of mathematical knowledge and effective learning strategies. Therefore, teachers should create problem situations that are conducive to students’ inquiry and study according to the specific learning content and the knowledge level of students so as to enable students to master the methods of inquiry and explore the fun of exploration in their own exploration and cooperation and exchange. teach
