1　引言随着物理信息和知识迅速增长 ,物理教师和课程开发者想通过在同样多的课堂时间里尽可能涉及较多的事实内容来满足知识和信息增长的需要 .然而最新的有关教学和学习的研究清楚地表明 ,用过多的事实培养学生的教育策略是失败的[1] .鉴于此 ,“少就是多”的观念得到物理教 1 Introduction With the rapid growth of physical information and knowledge, physics teachers and curriculum developers want to meet the needs of knowledge and information growth by involving as much factual content as possible in the same amount of class time. However, the latest teaching and learning The study clearly shows that the educational strategy of cultivating students using too many facts is a failure [1]. In light of this, the notion of “less is more” has been taught by physics.
