Abstract

The mathematical reasoning ability in understanding mathematical material in high school students still has not touched perfect scores. A valid and reliable instrument is needed in measuring mathematical reasoning skills in students. Validity and reliability testing of the instrument is carried out to ensure whether an instrument can be used to provide accurate results in a measurement being performed. Therefore, this study aims to determine the level of validity and reliability of mathematical reasoning skills in students using Winsteps. The method used in this study is a quantitative survey method, with 252 respondents in high schools in Jakarta. This study uses 3 indicators that are a reference in measuring the mathematical reasoning ability possessed by students. The validity test on the instrument shows that all items on the instrument are valid because they meet the criteria of MNSQ, ZSTD, and Pt Mean Corr except for item 1 which has a ZSTD value of > 2.0 and item 3 has a ZSTD value of < -2.0. Meanwhile, the reliability test obtained an Alpha Cronbach calculation of 0.74 which means that the value of the reliability item is high so that the instrument is declared reliable for use. The DIF analysis using winsteps shows that all question items used in the instrument are valid because none of the question items contain bias referring to the DIF Analysis criteria, namely the DIF Contrast value > 0.5 and the probability value < 0.05 where all the value of the question items actually obtained a DIF Contrast value of < 0.5 and a probability value > 0.05.

Abstract

In Indonesia, students' reasoning ability is still very low, especially in mathematical reasoning ability. It was found that the data of mathematical reasoning ability test results of class X students where only 47.22% reached the minimum learning completeness. Reasoning ability also plays an important role in the process of thinking creatively, logically, and systematically so that students can conclude solutions from several known facts as well as proof of mathematical statements, find new ideas, overcome challenges in solving mathematical problems, and reduce dependence on memorization. This study aims to determine the validity and reliability in mathematical reasoning ability of high school students using two statistical applications, namely SPSS and Winstep. The research method used is a quantitative research method with a survey approach, which has a total of 252 respondents from class X high school students in Jakarta. The results of the validity test research using SPSS have 6 valid items so that they are in accordance with the criteria. While the results of the validity test using Winstep there are seven items that do not match the three, and there are twenty-nine items that only meet one requirement, so 154 items must be maintained because they are fulfilled. Meanwhile, the results of reliability calculations using SPSS and Winstep obtained the results (α = 0,74). By using two different statistical applications, namely SPSS and Winstep, it can be stated that the results of the mathematical reasoning ability test have been declared valid and reliable.
