Abstract
Teachers should not only understand the basic knowledge of the course, but also master the overall structural characteristics of the course, grasp the important and difficult point of the course, and optimize the knowledge structure of the course. This paper mainly applies complex network to the analysis of course knowledge structure to construct and optimize the knowledge network of Educational Technology course. Firstly, the textbook and syllabus of Educational Technology course are used as a data source, and the course knowledge network model is constructed. Secondly, the knowledge nodes and their relationships are determined, and the course knowledge network is constructed. Thirdly, by using topological sorting based on directed graph, the course knowledge structure is optimized. And the pre-optimized and optimized course knowledge network are compared and analyzed, it shows the optimized course knowledge structure has superiority. It proves that the optimized course knowledge structure is more hierarchical, sequential and structural, which can highlight the main line of knowledge and clear the learning ideas. Finally, according to the results of comparative analysis of the pre-optimized and optimized course knowledge network, the teaching suggestions are proposed, and it is to realize the aim of optimizing teaching.
Highlights
With the progress and development of national education, course is an important part of school education, and knowledge is an important educational resource
The course reform should be designed in the era of information technology, and this can play the role of information technology in teaching”
The knowledge points are completely “isolated”, and the knowledge points learned by students are not systematic and incomplete [2]. (2) The important and difficult points in the course teaching are not prominent, and the teaching content and objectives are not clear
Summary
With the progress and development of national education, course is an important part of school education, and knowledge is an important educational resource. If only the text information or statistical data is used to represent the structure of the course knowledge network, it may lead to the lack of many data information, and it is extremely difficult to observe In this context, it is important to analyze and study the Educational Technology course knowledge network. By applying complex networks to the analysis knowledge structure, an objective and scientific course knowledge structure analysis method is established This can help teachers understand the overall structural characteristics of the course, and grasp the important and difficult point of the course. This can enable students to construct a good overall cognitive structure, and to establish a clear knowledge line and learning ideas. According to the comparative analysis results of the pre-optimized and optimized course knowledge network, the corresponding teaching suggestions are proposed, and this is to realize the purpose of optimizing teaching
