| Summary: | Geometry is a branch of mathematics that demands creative thinking. Teachers need a geometry instrument that is fun, simple, and meaningful to measure the creative thinking ability of junior high school students. This developmental research used a 4-D model consisting of defining, designing, developing, and disseminating the tangram-based geometry test. This research was intended to describe the process of developing a tangram-based geometry test. Tangram-based geometry test development included validation by experts. The product has passed the validation stage and obtained a score of 4,47 (scale 1-5), so it was feasible to use. Research try out subjects were 3 out of 30 students who were VIII grader at junior high school that was chosen due to van Hiele levels. Data on students' creative thinking profile acquired through tests and interviews. Fluency, originality, flexibility, and elaboration are the aspects of creative thinking ability. The results showed that in solving tangram-based geometry tests, a student at the creative level (level 3) satisfied all aspects of creative thinking, a quite creative student (level 2) satisfied fluency and flexibility aspects, and almost uncreative student (level 1) satisfied fluency aspect only. According to the results, this developed tangram-based geometry test was valid, feasible, and effective to measure junior high school students' creative thinking ability |
