Abstract:

Certain concepts (X, B) can be obtained via the combination of skill multimaps with property-oriented concepts, which leads to a method for constructing knowledge and skill structures that can be applied to the adaptive assessment of skills. The processis as follows. First, expert teachers provide the question set Q, skill set S, and their corresponding skill multimaps (Q, S; μ). Next, the knowledge and skill structures are obtained from the extension and the intention of (X, B). Thereafter the knowledge structure is used to conduct the adaptive assessment of the sample, and the proportion of their knowledge states is calculated. Subsequently, the equal proportion selection rule of knowledge space theory "binary responses" is optimized to the sample proportion selection rule, facilitate faster assessment effects for examinees in different regions and age groups. Finally, the figure of learning paths for skill sets is drawn.

Key words: knowledge structure, skill structure, learning path, skill context, property-oriented concept
