摘要 在程序性知识的评估中,技能是指与项目的解决相关的操作路径.基于程序性知识的学习评价,文中提出由项目自身的状态结构诱导多分知识结构的方法,目的是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过程设定响应值,得到项目特定的响应值集.通过项目状态转移函数定义项目状态空间,将问题空间推广到多分情形.然后,由操作路径导出合取的技能映射,讨论由合取的技能映射诱导的多分知识结构.结果表明由技能映射通过合取模型诱导的多分知识结构满足逐项交封闭.最后,给出诱导多分知识结构的算法步骤,并举例说明算法的有效性.

Abstract:In the assessment of procedural knowledge, skills refer to the operation paths relevant to the solution of an item. Based on the learning assessment of procedural knowledge, a method of delineating polytomous knowledge structure from the state structure of the item itself is proposed to establish a polytomous assessment system for problem solving. Firstly, the response values are set according to the solution or operation process of each item to obtain the item-specific response value set. The item state space is defined by item state transition function, and the problem space is extended to polytomous case. Then,the conjunctive skill maps are derived from the operation paths, and the polytomous knowledge structures delineated by the conjunctive skill maps are discussed. The results show that the polytomous knowledge structure delineated by a skill map based on the conjunctive model satisfies the item-wise intersection closure. Finally, the algorithm steps of delineating polytomous knowledge structure are given, and the effectiveness of the proposed algorithm is illustrated by an example.
