动画演示与算法教学研究

算法向来就是计算机教学中的难点，一般算法教学方法很难有效帮助学生理解算法。通过分析算法动画演示的认知作用，强调只有好的算法动画演示才能有效促进算法学习，然后从认知主体需要出发，提出设计好算法动画演示的四个原则。说明只有认真调查研究每一个算法的演示目标和重点，合理安排演示内容和形式，才能设计出一个好的算法动画演示系统。

Research on Animation Demonstration and Algorithm Teaching

Algorithm is always difficult in computer teaching. The general method of teaching is very difficult to effectively help students understand the algorithm. By analyzing the cognition effects of algorithm animation it is demonstrated that good animations can facilitate algorithms studying. For designing good algorithm animations, proposes four principles from the needs of cognition subject. It comes to conclusion that, in order to implement a good algorithm animation, not only the goals and key points of its interpretations should be investigated carefully, but also its contents and display forms should be arranged reasonably.
