Effectiveness of PBL STEM to Improve Problem Solving Skills

STEM PBL emphasizes integrating several aspects of science, such as technology and design, where in this aspect, there will be an innovative engineering process based on science mathematics that aims to carry out innovation problem-solving. The research design is a non-equivalent pre-test post-test control group design—the tests conducted by the learning experiment groups. were two classes with different treatments; class used model, while was treated using conventional model. results present average percentage student’s problem-solving experiments increased after implementing More students experts all compared pre-test.
