The study attempts to find the effect of using STEM-PBL design to improve problem solving skills. This type of research is descriptive research with a quantitative approach. The sample used in this research are classes X as an experiment class, with 25 students. The learning process is carried out by online learning using zoom meetings. The data were collected using Pre-Test and Post-Test designs. The Lesson Plan used in the learning process has been validated. The result of validated is 4.62, with a very good category. The result of the effect using STEM-PBL design to improve problem solving skill is obtained from standard gain. Standard gain is obtained 0.3, with a very low category. This indicates that the problem solving skills of student using STEM-PBL design is increasing. © 2024 Author(s).
