This article discusses the preliminary stage of research on the development of problem-based learning (PBL) tools for high school student. At the preliminary stage of the research, observations and interviews were conducted with mathematics teachers and high school student in class XI. Based on the results of the observation and interviews, the learning device used are still of a general nature and have not allowed the student to improve their mathematical problem-solving skills. Student rarely uses the LKPD and if the teacher does not do so, the content contains little material and many questions that did not allow the student to chat with friends or groups and present contextual problems. In the RPP, there is no step in the learning model used, so sometimes it does not meet the conditions and needs of the student. © 2019 IOP Publishing Ltd.
