建构主义的学习观认为,学习不应被看成是学生对教师所传授知识的被动接受,而是一个以学生已有知识经验为基础的主动建构过程.而创设问题情境就是这种让学生主动探究的有效手段.什么是创设问题情境呢?创设问题情境就是指教师精心设计一定的客观条件,如提供学习材料、动手实践、解决问题的方法等,有意识地设疑问、立障碍、布迷局、揭矛盾,从而使学生对数学知识处于欲求不得,欲言不 The constructivist view of learning believes that learning should not be viewed as a passive acceptance of students’ knowledge imparted by teachers, but an active construction process based on students’ existing knowledge and experience. Creating problem situations is what makes students active. The effective means of inquiry. What is the creation of problem situations? Creating problem situations means that teachers carefully design certain objective conditions, such as providing learning materials, hands-on practice, and methods for solving problems, etc., and consciously design questions, obstacles, and fandoms. , exposing contradictions, so that students are not interested in mathematics knowledge.
