| 摘 要： | 过程调用作为Visual Basic程序设计的难点及重点之一,初学者对其中不同参数传递方式很难理解和掌握。为此提出了过程调用结合内存管理的新教学方法,将内存概念引入过程调用,通过分析计算机内存管理和Visual Basic程序运行的相互关系,对过程间不同参数的传递方式进行了解析,将抽象的过程执行步骤以直观的内存管理图示表现出来,帮助学生理解Visual Basic过程调用中的参数传递方式。该方法在教学实践中取得了良好的效果。

| Abstract: | Procedure calling is one of the difficulties and emphasis in Visual Basic programming. It＇s uneasy for the beginners to understand and grasp that transfer modes of different parameters in the procedure calling. With years of experience in the practice teaching, a new teaching method incorporated with procedure calling and main memory management is proposed. The concept of main memory is introduced to procedure calling. Through analysis on the relationship of main memory management and Visual Basic program running, transfer modes of different parameters in Visual Basic procedure calling are explored. The abstract running steps in the procedure calling are displayed by definite main memory management graph. It helps students understand the way of parameter passing in Visual Basic procedure calling, which has achieved good effect in teaching practice. |
