Covariance Analysis of Business Student’s Mathematical Performance Model: A Case of Khon Kaen University International College
Chawis Ketkaew

Abstract

       This research paper places an emphasis on the association between mathematical skills and the qualifiations of students whose mathematics related courses were taught in English. Business students in Khon Kaen University International College were used as samples. This study tries to determine the qualifiations which may affect the academic performance of students in math related courses. The study employed Log-linear multiple regression as a tool to represent this relationship. The signifiance of each factor was then tested using the Lagrange Multiplier Test (LM test). The results yielded from Covariance Analysis, suggested that the student’s ages signifiantly demonstrate a negative correlations between older students and lower scores. As they aged their scores decreased. On one hand, Sciences/math subject area from high school interacts signifiantly with both student’s age and their English skill – negatively for age and positively for English skill. Moreover, the three nationalities of students – Thai, Chinese, and Vietnamese – interact signifiantly with student’s ages and moves in the same direction. Lastly, quadratic relationships were expressed on both students’ ages and their IQs, implying that as student’s ages and IQs increase, their academic performances in mathematics related courses increase with increasing rates.
