Problem solving skill is one of six topical areas of physics education research, whereas the research about implementation of Project Based Learning-Science Technology Engineering and Mathematics (PjBL-STEM) to develope students- problem solving skills is still limited. This research aimed to reveal the effect of PjBL-STEM on students- problem solving skill in the topic of electromagnetic induction with a quasi experimental research with Pre- and Posttest Design. Grade XII students of Senior High School 2 Pasuruan Indonesia were distributed to Experiment class (PjBL-STEM) (N=36) and Comparison class (PjBL) (N=38). Students worked on two projects, which were light shake and transformator. Problem Solving Skills Test with 0.681 Cronbach-s alpha reliability was used as research intrument. Data analysis was done with t-test, N-gain and effect size. The result showed PjBL-STEM acquired significantly higher problem solving skill than the PjBL. Both classes had medium category in the skill-s improvement. With “Very Large” effect size, the practical implementation of PjBL-STEM model had very large impact than PjBL class in increasing students- problem solving skill. The final questionairre revealed students in both classes had positive response (Agree and Strongly Agree), which were quite similar towards the implementation of the learning model.
