技能映射通过析取模型诱导的多分知识结构

基于程序性知识的评估，提出由项目自身的状态结构诱导多分知识结构的方法，以建立适用于问题解答的多分评估体系.首先，根据各项目的解答或操作步骤设定响应值集，通过项目状态转移函数定义项目状态空间；然后，用操作程序表示技能，由过程函数导出析取的技能映射；最后，讨论技能映射通过析取模型诱导的多分知识结构.结果表明：技能映射通过析取模型诱导的多分知识结构是多分知识空间.

Polytomous Knowledge Structure Delineated by Skill Map Through Disjunctive Model

Based on the assessment of procedural knowledge, one method of delineating polytomous knowledge structure from the state structure of the item itself is proposed to establish a polytomous assessment system suitable for problem solving. Firstly, the response value set is set according to the solution or operation steps of each item, and the item state space is defined by the item state transition function. Next, skills are represented by operation procedures, and the disjunctive skill maps are derived by process functions. Finally, the polytomous knowledge structures delineated by skill maps through disjunctive model are discussed. The results show that any polytomous knowledge structure delineated by a skill map through disjunctive model is a polytomous knowledge space.
