摘　　要：学习者在认知过程中可能掌握了某些知识点,但自身的知识状态并未改变,因此,为了提高学习效率并对学习者进行知识评估,在知识点网络下运用形式概念分析方法讨论如何对学习者进行知识评估和学习路径选择问题.首先,给出了知识点网络的构造方法、有效知识点组合的概念及知识点网络下题库的构造方法;其次,通过知识点网络诱导知识点背景,在已知学习者知识状态的情况下对学习者掌握的知识点进行评估,并给出知识点网络下的学习路径图及其算法;最后,通过实验验证了提出的算法的有效性和可行性.研究发现,由知识点网络诱导的知识点背景确定的知识点结构满足良级性.In the cognitive process,learners may master some knowledge points,but their own knowledge state does not change.Therefore,in order to improve the learning efficiency and assessment of the learners'knowledge,this paper discusses how to assess the learners'knowledge and select learning paths for learners by using formal concept analysis method under the knowledge⁃point network.Firstly,the construction method of knowledge⁃point network,the concept of valid knowledge⁃point combination and the construction method of question bank under the knowledge⁃point network are given.Secondly,the knowledge⁃point context is induced by the knowledge⁃point network.Furthermore,in circumstances known learners'knowledge state,the knowledge point mastered by learners are assessed and the learning paths diagram and its algorithm under the knowledge⁃point network are given.Finally,the effectiveness and feasibilities of the proposed algorithm are verified by experiments.This research finds that the knowledge⁃point structure determined by the knowledge⁃point context induced by the knowledge⁃point network satisfies the well⁃graded.
