Abstract

This study aimed to produce a student worksheet based on Problem-Based Learning on curved solid geometry that was valid, practical, and had a potential effect on the mathematical problem-solving abilities of ninth-grade students of SMP Negeri 13 Palembang. The research method used followed the Tessmer development model (1993), which consisted of the preliminary phase (preparation and design stage) and the formative evaluation phase (self-evaluation, expert review, one-to-one, small group, and field test). From the results of the study, it was concluded that the developed LKPD was highly valid with a score of 87.69 and was highly practical based on the trial results across three stages: one-to-one (81.78), small group (84.67), and field test (84.33). Furthermore, it had a high potential effect on students' problem-solving abilities, with an average score of 79.71. The LKPD can be used to support student-centered learning in junior high schools.
