在选修本(人民教育出版社出版)中的《匀速圆周运动万有引力定律》教学内容结束后,笔者注意到,学生关于地球卫星的涉及运动学方面的知识,大多是零碎的,片面的,缺乏对所学习过的物理现象、物理情境的清晰的、有条理的、系统的认识。学过万有引力、天体运动后,有些学生仍只能机械地套用某种类型,乱代一些公式,不能把习题中卫星运动的情况通过练习,变成自己知识结构的有机组成部分,活学活用,也不能实现知识的正向迁移。
After the end of the teaching content of the law of uniform gravitational circular motion gravitation in the elective book (People’s Education Publishing House), the author noticed that most of the students’ knowledge about the earth satellites involving kinematics is fragmentary, one-sided, and lacking A clear, systematic, systematic understanding of the physical phenomena and physical situations that have been learned. After learning about gravitation and celestial bodies, some students can only mechanically apply certain types and formulate some formulas. They cannot use the practice of satellites in exercises to become an organic part of their own knowledge structure. Nor can the positive transfer of knowledge be achieved.
