提出问题、分析问题和解决问题贯穿于数学学习的全过程,而解决问题将学生已有的知识结构得以运用,学生已有的学习的动机得以调动,已有的学习方法得以迁移,以利于形成学生数学知识的整体框架,获取解决新问题的能力。课程标准中指出:“数学教学活动必须建立在学生认知发展水平和已有的知识经验基础之上。教师应激发学生的学习积极性,向学生提供充分从事学习活动的机会,帮助他们在自主探索和合作交流的过程中,真正理解和掌握基础的
To raise questions, analyze problems and solve problems runs through the whole process of mathematical learning. To solve the problems, we can use the existing knowledge structure of students, motivate students to learn, and transfer existing learning methods to facilitate the formation The overall framework of students’ mathematical knowledge, access to new problems to solve the problem. Curriculum standard states: ”Mathematics teaching activities must be based on the level of cognitive development of students and existing knowledge and experience based on teachers should stimulate the enthusiasm of students to provide students with full access to learning activities to help them in the autonomy Explore and cooperate in the process of communication, truly understand and grasp the foundation
