摘要
论述了智能教育物理平台建设过程中基于图元知识表示的必要性 ,分析了现有辅助类教育软件的不足 ,提出了一种基于分解与组合思想和学科领域知识结构特征的层次图元知识表示方法 ,其目的在于将物理问题求解和物理实验仿真的问题表达统一于相同的图元知识元件中 .已有的研究表明 ,这种表示体系是可行的 ,它有直观、清晰和自然的优点 .
The necessity of plot-based knowledge expression in the building of intelligent education platform of physics is discussed. The main shortages of current computer aided education systems in physics are pointed out. And then, an expression method which is based on the idea of decomposition and combination and the structure characteristics of subject fields is presented, that is the plot-based knowledge expression in hiberarchy style. Its motive is to unify both the physics' issue solution and experiment imitation expression into a unified form of plot-based knowledge element. The investigation indicate that this kind of expression system is applicable, frank, in focus and naturalness.
