波利亚认为:“学习任何东西的最好途径是自己去发现,为了有效地学习,学生应当在给定的条件下尽量多地自己去发现要学习的材料。”数学课程标准指出:“数学教学应从学生实际出发,创设有助于学生自主学习的问题情境,引导学生通过实践、思考、探索、交流获得知识,形成技能,发展思维,学会学习,促使学生在教师指导下生动活泼地、主动地、有个性地学习。”因此,在数学课堂教学中,教师要改变传统的讲授模式,敢于放手引导学生利用已有的知识经验自主解决新问题,使学生的主体地位得以凸现。一课堂教学中要培养学生的自主学习意识自主学习,顾名思义就是学生依靠自己的努力,自觉、 Polygamy argues that “the best way to learn anything is to discover for yourself that in order to learn effectively, students should find as many sources of learning materials as they can under their own conditions.” “The mathematics curriculum standard states: ”Mathematics teaching should proceed from the students’ reality and create the problem situations that help students to learn independently. Students should be guided through practice, thinking, exploration and exchange to acquire knowledge, develop skills, develop thinking, learn to learn, and make students lively and vividly under the guidance of teachers Therefore, in the mathematics classroom teaching, teachers should change the traditional mode of teaching, dare to guide students to use existing knowledge and experience to solve new problems autonomously, so that students can highlight the dominant position . A classroom teaching to develop students’ autonomous learning self-learning, as the name suggests is that students rely on their own efforts, consciously,
