Developing a New Quantitative Reasoning Test for Indonesian High School Students using the Cattell-Horn-Carroll (CHC) Theory of Intelligence

摘要

This study aimed to develop a new intelligence measurement based on the CHC theory of intelligence; specifically, a quantitative reasoning test for tapping into high school students' interests. The test consists of two subtests: deductive quantitative reasoning (QR-VA) and inductive quantitative reasoning (QR-DA). There are 25 items of verbal arithmetic questions for QR-VA and 30 items of number series questions for QR-DA. Reliability analysis using Cronbach Alpha showed that QR-VA did not have good internal consistency, while QR-DA had good internal consistency. Validity analysis using correlation with Tes Kemampuan Diferensial (TKD) showed that both quantitative reasoning subtests are valid for measuring quantitative reasoning abilities. Furthermore, results from item analysis showed that the quantitative reasoning test has varying degrees of difficulty level and is able to discriminate quantitative reasoning abilities of high school students. For the final version of the test, 15 items were selected for QR-VA and 20 items were selected for QR-DA with appropriate degrees of difficulty. The within norm group with standard score of M = 10, SD = 3 were used as QR test norms.
