《牛顿第一定律》揭示的规律比较抽象,与学生的日常体验相悖。教学时,我发现多数学生只能了解其大概,不能真正理解其含义。这就促使我进行理性思考,试图从厘清理论区别和理解运用两个方面,帮助学生学好牛顿第一定律。 The law revealed by Newton’s First Law is rather abstract and contrary to the daily experience of students. When teaching, I found that most students only knew about it and could not really understand what it meant. This prompted me to think rationally and try to help students learn Newton’s First Law from clarifying the differences and understanding of the theory.
