Clustering the English Reading Performances by Using GSP And GSM

Abstract

The purpose of this paper is to apply an integrated approach to cluster the English reading performances among college students because finding the optimal teaching strategy for an individual student is difficult. The unified English reading exam with forty questions was used to clarify the different performances between day-time and extension classes which have thirty-eight students and thirty-seven students, respectively. The Grey Student-Problem(GSP) chart, which includes the equation of Rasch model, was then generated. Then the method of Grey Structural Modeling (GSM ) was used to cluster the students into appropriate groups. According to the GSP chart and GSM, students' reading performances are clustered into classes based on their levels. Finally, we used Interpretive Structural Model (ISM) to display the concept structure of each group. The results indicate that the teachers could provide adaptive teaching methods and remedial instructions based on the graphic models. Also, parents could understand their children's learning conditions better by reading the clear graphs. We suggested that the GSP chart can not only be applied to the educational field, but also be used in real-life applications, like medical data analysis, engineering, or decision-making fields.
