摘　　要：为了实现高校计算机教学中提高学生理论学习水平,增强学生动手能力的目标,本文通过设计一个决策树构建的综合实验过程,使学生掌握VB程序设计中的几个关键问题:1)学习设计解决问题的算法,通过学习信息熵构建决策树的算法,采用信息熵算法对学生成绩表分类并构建决策树;2)学习VB语言与数据库的操作,选择当前应用广泛的SQL数据库存储学生成绩表数据,并作为VB程序的直接操作对象;3)学习递归编程及应用,信息熵构建决策树的算法适于采用递归编程。综上所述,本文将实验分解成3个学习任务,使学生不断提高算法学习及语言编程的综合能力。In order to enhance the theoretical study level and strengthen the practical ability of students in the computer teaching in universities, this paper through a comprehensive experiment design of a decision tree construction process to enable students to master a few key problems in VB programming： 1）learn the algorithm to solve the problem, by learning information entropy algorithm to construct decision tree on the score table; 2）learn VB language with the operation of the database, select current widely used SQL database to store student score data, and as the direct object of operations to the VB program; 3）learn recursive programming and application, information entropy algorithm to construct decision tree is suitable to use recursive programming mothed. In summary, the experiment is divided into three learning tasks and enable students to improve algorithm learning and language programming ability.
