美国心理学家布鲁纳指出:最好的学习动机是学生对所学知识本身的内部兴趣。这一观点已经取得了教育界的共识教学实践充分证明,兴趣是最好的老师,学习数学尤其如此。数学知识抽象枯燥,知识点连贯,环环相接,若学生不具备学习兴趣,或是学习兴趣知识一时的和一阵子的,那么,数学知识就一定不会掌握好。进一步说,学生的知识和能力只能来源于自身的学习活动。培养学生学习数学的兴趣,引导他们自主学习,是培养学生具备各方面能力的需要。我们试想一下:素质教育的主 Bruna, an American psychologist, pointed out: The best motivation for learning is the student’s internal interest in the knowledge he or she learns. This view has gained consensus in the education sector. Teaching practice has proved that interest is the best teacher, especially in math. Mathematical knowledge is abstract and boring, the knowledge points are coherent and connected with each other. If the students do not have the learning interest or the knowledge and interest in learning for a while, then the knowledge of mathematics will not master it well. Further, students’ knowledge and ability can only come from their own learning activities. Fostering students’ interest in learning mathematics and guiding them to learn independently is a need to train students in all aspects of their abilities. Let us imagine: the main quality education
