Abstract

Mathematical creative thinking is an important skill for students to face global challenges and advances in science and technology. However, previous research shows that this skill is still low among Indonesian students. Accurate measurement can be ensured by valid and reliable instruments. The purpose of this study is to evaluate the validity and reliability of the mathematical creative thinking ability test instrument using the Rasch Model and SPSS. The research method is quantitative with a survey approach, involving 106 participants from various demographic backgrounds. The results of the validity test using the Rasch model showed that the eight items on the mathematical creative thinking ability test instrument met the criteria with the ideal value range for Outfit MNSQ, Outfit ZSTD, and PTMEA-CORR. In addition, the validity test results using SPSS show that the eight items have a correlation coefficient value that exceeds the r product moment value. The results of the analysis showed that the instruments tested were valid and reliable with a Cronbach's Alpha value of 0.73 using the Rasch Model and SPSS. However, the Rasch Model showed 24 persons that did not fit, which means that the Rasch model's ability to provide more specific results. Both methods can be used effectively to measure the validity and reliability of mathematical creative thinking test instruments and the Rasch Model provides more detailed information in identifying persons who do not fit

Abstract

Creative thinking skills are important skills in the world of education, but students are less enthusiastic when solving math problems which causes students' mathematical creative thinking skills to be low. This study aims to determine the validity of students' mathematical creative thinking skills on quadratic function material with the Rasch Model. This study uses a quantitative method with a survey approach. The subjects of this study are 106 students consisting of school students, this research is carried out by testing instruments on research subjects. Through the instrument, there are four indicators consisting of eight questions that are tested for validity and bias using the Rasch Model, the results are that all items are declared fit on the validity test, 24 people are declared misfit, with a reliability test score of 0.73 including high criteria and seven items are indicated as biased items.
