基于数据库与控件设计的CAI课件的开发与研究

Development and Research on a CAI Courseware Based on the Database and Control

通过传统关系数据库来管理CAI课件中的教学内容,即将CAI课件中所用到的文本、音频、视频和图像按具有网状结构的数据表进行录入。通过修改具有网状结构的数据库内容来达到修改或补充CAI课件的教学内容。该方法切实可行,所制作出的CAI课件具有良好的交互性、扩展性和容易推广使用。

Through traditional relational database to manage the content of CAI courseware, to record the text, audio, video and images into a mesh-structured data entry table. The contents of the mesh-structured database was modified to recondition or change the teaching contents of CAI courseware. The methods is feasible, and the CAI couseware has a good interactivity, expandability and easiness for wide-range applicability.
