摘要：A descriptive research which is purpose to describe pre‐service teachers’ ability in designing a mathematics learning devices using problem-based learning models were done. The subjects of this research were pre‐service teachers who programmed Innovative Learning course consisting of 32 people. Data collection was carried out using the assignment method, while data analysis was carried out by paying attention to whether or not students were able to (1) formulate indicators based on basic competencies, (2) formulate learning objectives based on learning indicators, (3) design subject matter in accordance with learning objectives, (4 ) choose learning materials that are in accordance with the learning model or method, (5) design learning activities according to learning objectives, (6) design "constructivist" worksheet (7) design assessment instruments according to learning indicators, (9) alternative answers according to the questions asked. prepared, (10) The scoring guidelines are in accordance with the prepared test questions. Based on the results of data analysis, it can be stated that pre‐service teachers are competent in designing learning devices using problem-based learning models. In addition, their mathematics learning devices using problem-based learning model have met good criteria.
