新课改特别强调学生问题意识和创新能力的培养,一方面强调通过问题情境促使学生主动学习,把“问题”看做学生学习的起点、贯穿在学习全过程的主线;另一方面通过学习来生成问题,把学习看成是发现问题、提出问题、分析问题、解决问题的过程。因此,在数学学习过程中创设有价值有意义的问题情境,目的是激活 The new curriculum reform emphasizes the cultivation of students ’problem awareness and innovation ability. On the one hand, they emphasize that motivating students to take the initiative to learn through the problem situations and “problem” as the starting point for students’ learning through the main line of the whole process of learning. On the other hand, Learning to generate problems, learning as a process of finding problems, asking questions, analyzing problems, and solving problems. Therefore, in the process of mathematical learning to create a meaningful problem context, the purpose is to activate
