面向问题解决的图形学教学改革探讨

The Exploration of Teaching Reform on Computer Graphics Oriented Solving Problems

根据当前图形学课程教学现状,文章总结分析了当前3种典型的教学体系,即面向理论、面向编程与问题解决,反思了传统图形学教学方法。在此基础上,给出图形学教学改革的3条具体建议:明晰教学目标,理顺教学内容,更新教学方法。同时给出"问题3W"式教学方法,它从计算机图形学内容中提炼出若干个经典问题,按问题组织教学内容,强调按问题探究(Why)—问题分析(What)—问题解决(How)的顺序安排教学。先激发学生的学习兴趣,再引导学生思考并获得知识,最后在掌握问题的解决方案过程中培养学生问题解决能力,以适应教学内容与教学目标的需要。

According to the current teaching status of graphics, the paper summarizes and analyzes three typical teaching systems： oriented theory, oriented programming and solving problems, and introspects the traditional teaching methods in graphics. On this basis, the paper gives three specific suggestions about teach ing reform on graphics： clear teaching objectives, straighten the teaching content, and update the teaching methods. The paper presents the ＂ Problem 3W＂ teaching method, which refines several typical problems from compute graphics, organizes teaching content by problems, emphasizes the teaching in the order of pro bing the problem （ Why ） analyzing the problem （What） solving the problem （How） . Firstly it can stimulate students＇interest in learning, and then guide them to think and get the knowledge. Finally, culti vate students ability to solve problems in the process of mastering the solution, so as to meet the demand of teaching content and objective.
