Research on the Construction of Subject Knowledge Gragh and Large Unit Design Based on Zone of Proximal Development
The knowledge organization methods in the era of artificial intelligence are undergoing profound changes.In subject teaching,there is an urgent need to clarify how to achieve holistic design.The design should be based on structured knowledge to cultivate the core literacy of the discipline.This research proposes a disciplinary knowledge development framework based on the theory of zone of proximal development.By focusing on the process of constructing subject knowledge graphs,it analyzes and implements the technical roadmap of subject knowledge graphs,extracts features and evaluates the quality of large units,and constructs an information technology subject knowledge graph for large unit design.Large unit design,as an integrated design concept,is guided by subject knowledge graphs,key elements,and basic steps of large unit design.Two types of large unit design patterns,namely,bottom-up and top-down,are proposed.Practical case studies demonstrate that subject knowledge graphs can reduce the difficulty of instructional design for practical knowledge,compensate for the deficiencies in areas such as student analysis for new teachers,and provide a basis for the design and implementation of large unit instruction to promote the deep application of structured knowledge in teaching.
