布鲁纳认为:在教学进程中学生是一个积极的探究者,教师的作用是要形成一种能够独立探究的情境,而不是提供现成的知识,这种由学生自己来发现知识的奥秘及内在规律的学习方法必定会促使学生参与学习活动的全过程,从而取得理想的学习效果。数学教学要在有限的教学时间内,提高课堂教学效率,必须成分发挥学生的主体作用,让学生全方位参与数学学习过程。基于这种指导思想,笔者在教学中作了一些初步的尝试。 Bruner believes that in the process of teaching students is an active investigator, the role of teachers is to form a situation that can be independently explored, rather than providing ready-made knowledge, which is to discover the mysteries and inherent laws by the students themselves Learning methods will inevitably encourage students to participate in the whole process of learning activities, so as to achieve the desired effect of learning. In a limited teaching time, mathematics teaching should improve the efficiency of classroom teaching. It is necessary for students to play the main role of composition in the teaching so that students can participate in the process of mathematics learning in an all-round way. Based on this guiding ideology, I made some initial attempts in teaching.
