One of the efforts to maintain the quality of physics learning during the Covid-19 pandemic is to apply blended learning using the discovery learning model. Learning physics at vocational high school needs to be carried out with learning innovations that refer to 21st century learning, namely developing problem solving abilities. This study has the objectives to (1) describe physics learning activities on blended learning using discovery learning models on dynamic electrical materials, (2) find out the effect of applying discovery learning models to problem solving abilities on dynamic electrical materials. This type of research is a quasi-experiment research using a non-equivalent control group design. The research method used is descriptive quantitative method. The research subjects were students of vocational senior high school class X motorcycle engineering competence. The number of students involved in the study was 34 students who were divided into 2 classes. The results of the research conducted, that (1) student learning activities in the experiment class were using discovery learning stages with practical methods. Students made a replica of a motorcycle turn signal circuit by applying the concepts and principles of dynamic electricity. Through practical activities in discovery learning, students find their physics concepts independently. At the end of the learning process, students made general conclusions about the application of physics in the automotive major. Then, (2) statistical test analysis and N-Gain showed that blended learning using the discovery learning model has a positive effect on improving the problem-solving abilities of students. There was a significant difference in the improvement of problem solving's ability between the experiment class and the control class. N-gain analysis showed that 83% of experiment class students are in the moderate improvement category. Meanwhile, in the control class, all students experienced an increase in the medium category. © 2024 Author(s).
