基于DRM的教学内容分析系统设计

The Software Design of a Course-content Analyzing System

为支持教学内容分析及教学设计实践,设计了基于DRM的教学内容分析系统.该系统具备信息输入、转换运算和结果呈现三项基本功能.教学内容分析系统将学习者的先修知识纳入信息输入环节,并在转换运算功能环节以DRM法取代ISM法,改善了系统对教学设计的支持作用.千次运行平均时间对比检测结果显示,DRM法可获得与ISM法完全相同的分析结果,但运算效率明显优于ISM法.

In order to support Instructional design practice,a course-content analyzing system based on DRM was designed.The system offered three modules,viz.information inputting,matrix conversion and result presentation.In the first module,the system asked for input about knowledge-points in course-content and their correlation,and it also asked for the information on existing knowledge of learner as a further effort to improve the function of the system.In the module of matrix conversion,DRM was brought into the course-content analyzing system to replace ISM to speed up the system computing.The numerical results of a test for ART indicated that it obtained the same results as the system based on ISM and DRM is computationally efficient.
