通过习题分析让学生充分认识建模的重要性

MAKING STUDENTS FULLY UNDERSTAND THE IMPORTANCE OF MODELING THROUGH FURTHER ANALYSIS ON SOME EXERCISES IN MECHANICS

力学课一个重要的任务是培养学生对建模的认识.刚进入大学的学生都很习惯解题,但他们并不清楚题目是如何来的.通过对一些习题的分析,可以让学生们理解一个实际问题是如何变成题目的,让他们认识到建立正确的模型对问题的解决至关重要.

One of the most important purposes of Mechanics Courses of College Physics is to cultivate the students＇ understanding on modeling. Although students in Chinese Colleges are used to solving class exercises, they don＇t know how the exercises are derived from the real problems. Through further analysis on some exercises, teachers can make students know how a problem becomes an exercise and understand the importance of proper modeling in solving the real problem.
