Teaching Case Study on Educational Reform Based on Hierarchical Domain Knowledge Reconstruction

Abstract

As the half-life period of knowledge is getting shorter and shorter, the mutual transformation between scientific research results and teaching content is an effective means to keep students updated with knowledge. Based on the principle of knowledge classification, this study takes the law of students' acceptance of knowledge into account and resolves knowledge into four “domains” of different levels: the basic domain, simulation domain, design domain, and exploration domain, so as to reconstruct the teaching content. In the basic domain and simulation domain, knowledge is mainly the traditional basic theoretical knowledge and the most advanced scientific results. In the design domain and exploration domain, students transform from knowledge recipients to knowledge applicators and developers, thus realizing the mutual transformation between scientific research results and teaching contents. Years of teaching practice shows that the reconstruction of teaching content based on Hierarchical domain knowledge has a remarkable effect on improving students' independent innovation ability.
