摘　　要：提出个性化认知结构的构建方法,为学习者主动推送合适的学习目标.形式化定义静态学科知识结构,通过属性扩展的方式表示学习者的认知结构;根据知识点前后有序、由易到难的特点和规律,对个性化认知结构进行层次划分;综合分析认知结构中节点的层次信息和关联强度,提出节点之间的学习影响程度计算方法,计算结果按照新知识点可学习期望值排序,循序渐进地为学习者主动推送合适的新知识点.Propose the construction method of personalized cognitive structure to actively push appropriate learning objectives for learners.Formally define the static subject knowledge structure,and express the cognitive structure of learners through attribute expansion;according to the characteristics and rules of orderly knowledge points,from easy to difficult,the personalized cognitive structure is divided into levels;by comprehensively analyz ing the hierarchical information and correlation strength of nodes in the cognitive structure,a calculation method for the degree of learning influence between nodes is proposed.The calculation results are sorted according to the learnable expected value of new knowledge points,and appropriate new knowledge points are actively pushed for learners step by step.
