Analysis of the Three-Way Decision Rules in Online Learning-Taking a Calculus Course as an Example

Abstract

To investigate the credibility of online examinations, we randomly chose 30 engineering students in Wenzheng College of Soochow University as a sample and established an information system S. According to pedagogy theory, students’scores are related to their intelligence levels, course basis, learning methods, and learning time. Therefore, in the information system S, “score of early semester,” “average score of class quizzes,” “completion ratio of watching videos,” and “completion grade of homework” were taken as the condition attributes, and “score of final exam” was taken as the decision attribute. We applied the three-way decision rules theory to provide positive, negative, and boundary decision rules for this information system S. Furthermore, we obtained confidence in the decision rules. The results of this study validate the credibility of online examinations and have certain guiding significance for online teaching and learning.
