从建构主义和能力本位理论出发, 提出了一种基于知识图谱的在线学习系统设计方法, 即打破传统的知识结构, 以提升能力为目标, 构建知识、技能等多维度的能力框架; 搭建了以知识图谱为底层逻辑, 链接数字学习资源的学习系统; 开展了教学实践和实证研究. 首先, 使用调查问卷对学习系统进行了验证; 其次, 以“阅读英文学术论文”能力为学习任务, 随机分配实验组和对照组; 最后, 评估两组对于知识、技能的理解、记忆水平以及综合运用能力. 研究结果显示, 学习系统的有效性和易用性实验组总成绩、知识得分、技能得分和能力得分均高于对照组成绩, 其中总成绩和能力得分具有显著性差异, 表明该系统对于在线学习效果有一定的促进作用.

Drawing on constructivism and competency-based theory, this paper proposes an online learning system design method based on a knowledge graph, which breaks the traditional knowledge structure and builds a multi-dimensional competence framework of knowledge and skills with the goal of improving competence. A learning system with a knowledge graph as the underlying logic and linked digital learning resources was built. Teaching practice and empirical research were then carried out. First, the learning system was verified with a questionnaire. Second, taking the ability to “read English academic papers” as the learning task, experimental and control groups were created to evaluate the understanding of knowledge and skills, memory level, and comprehensive application ability of the participants. The results showed that the effectiveness and usability of the learning system were higher in the experimental group than in the control group in terms of total, knowledge, skill, and ability scores. Among these, total and ability scores showed significant differences, indicating that the system played a role in promoting the effect of online learning.
