To be able to learn something well, we need to hear, see, ask questions about it, and discuss it with others. Not only that, students need to "do it", ie describe something in their own way, show examples, try to practice skills and do assignments that demand the knowledge they have acquired. The problems to be studied in this study are: (1) Can the application of problem-based learning models increase student achievement? (2) How does the problem-based learning model influence students' learning motivation? The objectives of this classroom action research are: (1) Want to know the increase in student achievement after the implementation of problem-based learning models (2) to find out how the impact of problem-based learning models on increasing student motivation.
