Research on The Construction of Course Knowledge Graph of High School Information Technology

摘要

Since Google proposed the concept of the knowledge graph in 2012, the research interest of the knowledge graph has been increased year by year. From the construction of more and more general knowledge graph to the hot research of domain knowledge graph in recent years, it will found that people have more in-depth research on knowledge, more refined granularity, and more stringent requirements on quality. In teaching, it is also essential to construct a course knowledge graph to assist in practical education. This article takes the new curriculum standard for the high school information technology compulsory book one "Data and Computing" and compulsory book two "Information System and Society" as examples. Based on the textbook organization, it designed a course knowledge graph that includes three types of knowledge units: chapters, sections, and knowledge points, and three semantic relationships: sequences, contains, and connects. Through the analysis of the basic structure and specific construction process of the course knowledge graph, this paper explores that the course knowledge graph can well support systematic learning, personalized learning, and other learning situations.
