随着课程标准的不断变革更新,要求教师要适应时代发展,不断更新改进教学模式,为了让课堂不再只是追求成绩的平台,也要注重对学生思维方法的培养,只有学生在思想意识上有所提升,才是老师的成功.初中物理教学中做物理习题时,老师要适当渗透物理思维,帮助学生提高解题速度.其中采用极值法能够解决一些按照常规方法难以解决的题目,通过对物理量的极限分析能够快速得出结论.下面列举几个利用极值法解题的例子,希望对相关学习有所帮助.
With the constant change and updating of curriculum standards, teachers are required to adapt to the development of the times and keep updating and improving their teaching modes. In order to make the classroom not only a platform for the pursuit of achievements, but also the cultivation of students’ thinking methods, only the students have the ideological consciousness Improve, is the teacher’s success.When doing physical exercises in junior high school physics teaching, teachers should be appropriate to penetrate the physical thinking, to help students improve the speed of solving problems.With the extreme value method can solve some problems that are difficult to solve according to conventional methods, Limit analysis of physical quantities can quickly come to the conclusion. Here are few examples of the use of extreme value method to solve the problem, hoping to help related to learning.
