动画技术在情境教学设计中的应用实践——《数据结构》三个典型案例的设计

摘要

教学过程中利用动画技术创设问题情境，激发学生的学习兴趣，提供学生自主探索的空间是教学取得成功的关键。结合《数据结构》课程的实践教学，论述了形象化情境、认知冲突情境、问题情境、反思情境等相关情境的创设策略。探讨了“利用栈结构探索迷宫路径”、“内部排序”和“图的遍历”三个典型案例的教学设计方案，在对实践效果进行评价分析的基础上，提出了进一步改进的思路。%In the teaching process, using animation techniques to create the problem situation, stimulating students＂ interest, and providing students with self - exploration of space are essential keys to the success of instruc- tion. In this paper, the construction strategy of visualized situation, cognitive conflict situation, problem situation, and reflection situation are discussed combined with the practical teaching of the Data Structure course. And three typical cases of instructional design program are studied, which uses stack structure to explore the maze path, internal sort and graph traversal. Finally, several ideas for further improvement are proposed based on the evaluation and analysis of practice effects.
