PowerPoint教学课件规则圈点工具的设计与实现

Design and Implementation of Regular Punctuation Tool for PowerPoint Teaching Courseware

在利用PowerPoint教学课件进行讲课时，为了更好的指引学生或者强调所讲内容，教师们往往会使用PowerPoint的实时圈点功能。但是，PowerPoint的实时圈点功能有一个较大的局限和不足：没有提供如直线、方框、圆圈、椭圆等规则图形的圈点功能，而只提供了涂鸦式画线圈点的功能。为此，该文设计并利用VB实现了一个规则圈点工具，有效的弥补了PowerPoint的这一不足。该规则圈点工具的使用，将能大大的提高教师利用PowerPoint课件进行多媒体辅助教学的效率和学生听课的效果，从而提高教学质量。

When teaching with PowerPoint teaching courseware， for better guide to students or emphasizing contents， teachers often use the real-time punctuation function of PowerPoint. However， there is a big limitation and shortage of the real-time punctuation function of PowerPoint：It provides no punctuation function by regular-graphics of line， rectangle， circle and ellipse but only provides punctuation function by doodling. For this reason， a regular punctuation tool for PowerPoint teaching courseware was designed and implemented using VB， which effectively made up for the shortage of PowerPoint. The using of this regular punctuation tool would well improve multimedia aided teaching efficiency of teachers with PowerPoint teaching courseware and the listening effect of students， and therefore it would improve the teaching quality.
