以活动为导向的有机化学知识图谱构建与实践

Construction and Practice of Activity-Oriented Knowledge Graph in Organic Chemistry

教育的全面数字化转型已成为我国教育发展的新赛道和突破口,规模化因材施教已成为数字时代教学新范式。知识图谱由于具有可视化知识关联、科学化教学决策和个性化自适应学习等教学优势,已成为教育数字化转型的重要抓手。基于超星泛雅平台知识图谱技术,提出以活动为导向的多模态知识图谱构建模型框架和知识图谱构建五原则,并通过“梳、导、联”三步构建了有机化学课程知识图谱。在此基础上,以“羟醛缩合和Claisen酯缩合反应”知识点教学为例,展示了知识图谱如何应用于有机化学混合式教学。本研究为化学教育领域基于知识图谱的教学改革提供了新的思路和实践参考。

The comprehensive digital transformation of education has emerged as new track and breakthrough in the development of education in China.large-scale and individualized education has become a new teaching paradigm in the digital age.Knowledge graph,due to its teaching advantages such as visualized knowledge relationships,data-driven pedagogical decision-making,and personalized adaptive learning,has become a crucial lever in the digital transformation of education.This paper,based on the knowledge graph technology of the Chaoxing Fanya platform,proposes a framework for activity-oriented multi-modal knowledge graph construction and outlines five principles for knowledge graph construction.Through a three-step process of“knowledge point organization,knowledge point importing,and relationship connection”,this paper constructs a knowledge graph for the organic chemistry course.On the basis of these works,this article uses the“aldol condensation and claisen condensation reactions”as the example of teaching content,demonstrating how the knowledge graph can be applied to blended learning in organic chemistry.This research provides new insights and practical references for teaching reform in chemistry education based on knowledge graphs.
