布鲁纳认为:“学习者在一定的问题情境中,经历对学习材料的亲身体验和发展过程,才是学习者最有价值的东西。”一个好的问题情境对于理解新的物理概念、形成新的物理原理、产生新的物理公式,或蕴含新的物理思想会有积极的促进作用。但是,有的教师只把问题情境当作点缀,还有一些教师设置的是没有思维价值的问题或不能引发学生思考的问题。要从根本上促进学生全面发展,教师要有目 Bruner argues that: “Learners experience the most valuable experience of learning materials in the context of a given problem, and experience the development of learning materials.” "A good problem situation is important for understanding new physics concepts , Forming a new physical principle, generating new physical formulas, or imposing new physical ideas will have a positive role in promoting. However, some teachers only treat the problem situation as an embellishment, and some teachers set problems that have no thinking value or can not lead students to think. To fundamentally promote the all-round development of students, teachers should have their own purposes
