This research was a development research that aimed at finding out the students’ problem solving abilities in mathematics using LSLC-Based STEM learning. This research used multiphase mixture method. This research was started by the development research using 4D, while the quasi experimental research using interpretest-posttest control group design. The research subjects were 32 students of IX th grade in MTsN 2 Jember in 2019/2020. The research sample used three classes, which were the IXF as a control class, the IXG as the first experimental class (1), and the IXH as the second experimental class (2). The research data were collected and tested for its validity. After the instrument was valid and the data were homogeneous and normally distributed, the research data were tested statistically using one-way ANOVA. The results showed that (1) the instrument had fulfilled the validity, practicality, and effectiveness criteria, and (2) the significance value (2-tailed) was 0,000 (p<0.05) which indicated that the application of LSLC-Based STEM learning had a significant effect on the students’ problem solving abilities.
