Test Instrument Development of Mathematical Problem Solving Skills

Abstract

Instruments that can measure mathematical problem-solving skills are very limited. The test instruments used in mathematics learning often measure memorization and knowledge skills. The purpose of this research is to develop a test instrument that can measure the ability to solve mathematical problems in prospective teachers in elementary school. This research is a research and development. Data collection techniques using questionnaires and tests. Data analysis using qualitative descriptive techniques and the Content Validity Ratio (CVR) formula. The results of this research are a test instrument consisting of a five-grain essay that measures math problem-solving skills. The instrument is of good quality and valid according to expert judgment.
