基于动态可视化分析的冒泡排序程序设计的探究式教学方法

An Inquiry Teaching Method Based on Dynamic Visualization Analysis for Bubble Sorting

冒泡排序是高校《C语言程序设计》教学中的重要难点,而传统的教学方法并不理想。学生易将课堂PPT演示的内容与程序语言代码割裂开来,无法建立其直接的联系。探讨使用一种基于调试工具的方法,观察程序中变量值动态变化,从而建立算法自然语言描述与代码描述的直接联系,使学生能够更好地掌握冒泡排序算法的原理,培养学生的独立思考能力和发散思维能力,取得了良好的教学效果。

Bubble sorting is important issue of the 'C programming language' teaching in universities,but the traditionalteaching method is not ideal. Student often separate the connection between PPT demo content and programcode,and can not establish their direct contact. This paper explore a debugging based technique,observe dynamic changeof the variable values,to establish the direct link between natural language description of the algorithm and code description,to make students better grasp the principle of bubble sort algorithm,develop students' independent thinking abilityand divergent thinking ability,and good teaching effect has been obtained.
