Abstract
Science learning itself aims to help students understand and master the facts and concepts of science in life which can then be applied and developed as a form of instilling a scientific attitude in students. However, learning science at school is one of the scourges of its own difficulties for students. Where students tend to experience difficulties when faced with a problem. Therefore we need a learning model to facilitate this. One of the learning models that can be used is the problem-based learning (PBL) model. The PBL model is a learning model that prioritizes student-centered. This PBL model can be combined with a learning approach to support the achievement of learning objectives, in this case, the problem-solving abilities and self-efficacy of students. One approach that can be chosen is the STEM approach. This research is a type of development research that refers to the steps of the ADDIE model. Based on the calculation of the Likert scale and percentage agreement, it was found that the product being developed was in a very valid category with an average of >90. While product reliability reaches an average of >90%, which means the product being developed is reliable. Because the results of the analysis show that the product being developed is valid and reliable, the product is feasible to use.
