Korean Students’ Responses to Non-Cognitive Variables Compared to Japanese and Singaporean Students Based on TIMSS Data

This study analyzed the responses of Korean students to interest, confidence, value, and instructional clarity in science and mathematics. To achieve this, the raw data of the recent student survey of TIMSS were analyzed. A one-way ANOVA was performed, and a post hoc test was performed. Additionally, a cohort analysis was performed to determine the changes when the fourth-grade students reached the eighth grade. The study results are as follows. First, interest and confidence were higher in the fourth grade than in the eighth grade. Second, in most cases, the average response of Singaporean students was the most positive, but in terms of interest and confidence in science in the fourth grade, the Japanese response average was generally the highest. Third, the average scores of Korean students on wanting to have a job related to their subject and knowing what teachers expect from them were low in both science and mathematics.
