基于形式背景构建多分知识结构与个性化指导学习的方法
The method of constructing polytomous knowledge structure and personalized instruction learning based on formal context
摘要
Abstract
The establishment of polytomous knowledge structure is helpful to evaluate the degree of individual mastery of the problem,and the operation procedure map is one of the important tools to construct polytomous knowledge structure.The operation procedure map refers to the map from the problem level set to the operation procedure set.In this paper,the operation procedure map is transformed into formal context,based on which constructing polytomous knowledge structure,finding learning paths and guiding personalized learning are proposed in conjunction model.Firstly,a method is proposed to solve the polytomous knowledge structure induced by conjunctive operation procedure map by constructing operation-procedure-oriented concept lattices.Secondly,the relationship between intensions in the operation-procedure-oriented concept lattice is studied.The path graph of learning operation procedure is introduced step by step,the method of personalized instruction learning is provided,and the corresponding algorithms are given.Finally,the chapter of"the root equation of a degree"is selected as the knowledge domain to analyze and verify the feasibility of the algorithm.关键词
