Development of Literacy Test Instruments to Improve Mathematical Concept Understanding in High School Students

Abstrak

This study aims to develop a valid and reliable mathematical literacy test instrument in measuring the understanding of mathematical concepts of Senior High School students. This development is motivated by the need to strengthen students' readiness in facing the Minimum Competency Assessment (AKM), which demands high literacy and numeracy skills. The development model used is four-D, with the steps being define, design, develop, and disseminate, which focuses on one of the materials in Senior High School, namely the System of Linear Equations with Three Variables. The instrument is designed to measure all indicators of mathematical concept understanding, namely the ability to interpret, apply, and connect concepts in real contexts, as required in AKM questions, as an evaluation of the implementation of the existing curriculum. The validation results show that the developed instrument is suitable for use as a measuring tool for mathematical literacy. The product of this development is expected to contribute to reducing the need for assessment instruments as practice materials for students in solving AKM problems and the need for mathematics learning under the existing curriculum.
