Abstract

This study aims to produce student worksheet based on Problem Based Learning on the material of curved side space shapes that are valid, practical and have a potential effect on the mathematical problem solving abilities of ninth grade students of SMP Negeri 13 Palembang. The research method used is the research method used is the development research method using the Tessmer flow (1993) which consists of the Preliminary stage (preparation and design stage) and the Formative Evaluation stage (self-evaluation, expert review, one-to-one, small group and field test). From the results of the study, it was concluded that the LKPD based on Problem Based Learning that was developed was very valid with a score of 87.69 and was very practical based on the results of the trial at three stages one-to-one (81.78), small group (84.67), and field test (84.33). Then it has a high potential effect on students' problem-solving abilities with an average score of 79.71.
