Development of mathematical learning style test based on “MINDSET” theorem for senior high school students

Abstract

The purpose of this research was to developing mathematical learning style test based on “MINDSET” theorem for senior high school students. The specific objective was shown the evidence of content validity by using the item objectives congruence (IOC), the evidence of construct validity by using the corrected item-total correlation (CITC) and using confirmatory factor analysis (CFA), and the evidence of the reliability by using Cronbach’s alpha. The research samples were 254 Rachineeburana senior high school students in first semester of academic year 2016. The mathematical learning style test in this research comprised 20 items which aimed to assess the mathematical learning style in 2 areas: 1) growth mindset ability (GM) and 2) fixed mindset ability (FM).

The research results were as follows. 1) The IOC was 0.67 - 1.00. 2) The construct validity by using CITC was 0.24 - 0.56 for GM items and 0.36-0.66 for FM items. 3) Regarding the CFA with the mathematical learning style test in the aspect of GM found that, the model fit the empirical data, the Chi-square test was 17.05 (p = 0.76, df  = 22), GFI = 0.99, AGFI = 0.97, RMSEA = 0.00, in the aspect of FM found that, the model fit the empirical data, the Chi-square test was 23.03 (p = 0.15, df  = 17), GFI = 0.98, AGFI = 0.94, RMSEA = 0.04. 4) Regarding the reliability of the whole mathematical learning style test in general by using Cronbach’s alpha was 0.76, when considering in the individual areas, it was found that the aspect of GM and FM were 0.72 and 0.83 respectively.
