Abstract

To explore and reveal the relationship between learning behavior and academic performance of higher vocational students, this study selects the original data of learning behavior and academic performance of 1,295 students from 19 majors in typical higher vocational colleges in southern Xinjiang. First, Python is used to clean and transpose the data to form a basic dataset. Then, grade points for each module are calculated based on teaching components including public courses, professional courses, elective courses, and graduation design (thesis), and the students' academic performance is determined according to the regulations of student status management in higher vocational colleges. In the dimension of learning behavior, the data of students' learning behavior in the library and dining behavior in the canteen are normalized and combined with academic performance to form a "learning behavior and academic performance" dataset. Subsequently, Python is used to implement clustering and outlier algorithms, and data mining is carried out on the dataset. On this basis, a decision tree model is generated, and the model is tested, evaluated, and visualized. This study provides a useful reference for exploring the relationship between students' learning behavior and academic performance.
