Abstract

Abstract: The purpose of this study is to produce the valid, practical, and effective problem-based questions to measure the mathematical problem-solving abilities of eighth-grade students of junior high school. The materials used as the basis of development are system of linear equation in two variables and the Pythagorean theorem. The development model used is the Plomp model consisting of three stages; preliminary research, prototyping phase, and Assessment phase. Based on the results of these stages, 16 problem-based questions were obtained which are valid to the criteria of content, constructs and determined language, practically used by the teacher, and effective for measuring students' mathematical problem solving abilities because they can direct students to identify problems, plan solutions, implement solutions, and need to carry out evaluations as indicators of problem-solving abilities.
