Formative Evaluation System of Online and Offline Blended Teaching Based on Grey Fuzzy Theory

Abstract

Both fuzzy theory and gray theory study “uncertainty problems”, and fuzzy theory belongs to the category of gray theory research and is a special case of gray theory research. Fuzzy gray evaluation can be understood as a method to evaluate things and phenomena with fuzzy factors under the premise of insufficient known information. Among them, “fuzzy” refers to the factors that the evaluation information has an unclear concept, and “gray” refers to the lack of information and insufficient information. This paper studies the grey fuzzy theory and its evaluation model, constructs the formative content of online and offline blended teaching, and develops the program interface by taking students' writing network mutual evaluation as an example. The research results effectively promote the application of modern information technologies such as the Internet, mobile terminals and cloud computing to blended teaching.
