这一篇談談刘先生講分子运动论这一理论系統在教学法上注意哪些原則。一、从感性到理性,从理性到应用刘先生每教一种抽象知識,必定先讓学生認识充分的必要的具体材料,决不使学生在这一个認識阶段不巩固就跳越到另一阶段。例如講气体、液体、固体、分子不同的运动,刘先生还巧妙地想出了这样一些启发学生思維的簡單实驗和实例,以使学生加深認識:(一)先按通常证明氢气比空气輕的做法,取一
This article talks about what principles Liu pay attention to in the pedagogy of molecular theory of movement. First, from perceptual to rational, from the rational to the application of an abstract knowledge of Mr. Liu, we must first allow students to understand the full and necessary concrete materials, not to enable students in this stage of understanding do not consolidate to jump to another stage. For example, speaking of gas, liquid, solid, and molecular movements, Mr. Liu also cleverly came up with simple experiments and examples that inspire students’ thinking in order to deepen their understanding of students: (1) By first generally confirming that hydrogen is lighter than air Practice, take one
