“C语言程序设计”实验教学的探讨

Discussion about Experimental Teaching of C Language Programming

上机调试程序是学生在学习“C语言程序设计”时遇到的困难之一。本文对作者所在系实的验教学环节中出现的现象和原因进行了分析 ,存在的主要问题如下 :教师要重复多次解答学生在调试程序时出现的同样的错误 ,导致效率低下且教师感觉累 ;由于学生人数多 ,教师不能即时解答每个学生的问题 ,会使学生出现懒惰、厌烦、消积的情绪 ;辅导中多数人是由教师操作计算机时 ,不利于学生领会程序调试的精髓。笔者提出了一个较好的方法可以解决上述这些问题 ,实践证明该方法有较好的效果。

The students have many difficulties during learning C Language Programming, and debugging program is one of these difficulties. In this paper, Phenomena and reasons coming from experimental teaching in our department are analyzed. There are the following main problems: the efficiency of teaching is not good and the teacher is very tired because helping the students to solve the same error is repeated many times; the students'questions are not answered by the teacher in time for too many students, so the students have the emotions of lazy, dislike and fear, and then do something which don't get touch with debugging program; by operating computer the teacher instead of the students makes them not to grasp the key of debugging program when directing students. The author provides a good method by which the problems above can be solved. It proofs that the new method get a good effect in experimental teaching.
