物理习题有着巩固物理知识,提高学生解决物理问题的能力的作用。在我们教学过程中也会选择一些适合学生学习和发展的物理习题作为学生的练习。有时为了更好地培养学生的思维能力,经常会将一些习题进行改编或是将现有的物理模型打散再重新搭建来命制一些较新的习题。这使得命题也成为我们教学工作的一种延伸,但在命题过程中也会出现一些失误,使得所命制的题目出现错误,导致事与愿违,达不到预期的效果。在命题时一些表述上、条件上或是 Physical exercises have the function of consolidating physical knowledge and improving students’ ability to solve physical problems. In our teaching process, we also select some physical exercises suitable for students to learn and develop as students’ exercises. Sometimes in order to better develop students’ thinking skills, often some exercises will be adapted or the existing physical model broken up and re-built to order some newer exercises. This makes the proposition also become an extension of our teaching work, but there are also some mistakes in the process of proposition, making the wrong title of the task, leading to the contrary, fail to achieve the desired effect.
