Penerapan model pembelajaran problem based learning untuk meningkatkan hasil belajar peserta didik SMAN 1 Kembang

. This study aims to determine the cognitive learning outcomes of students using the Problem Based Learning (PBL) learning model. The type of research used is Classroom Action Research (CAR) with a qualitative approach. This research was conducted online through Google Meet and Whatsapp Group for two cycles. The research activities include planning, implementation, observation/evaluation and reflection. The subjects of this study were students of class X MIPA-3 SMAN 1 Kembang. Data collection techniques using tests and interviews are then analyzed qualitatively. The results obtained are that in Cycle I there are 57% of students who reach the criteria of completeness and an increase in Cycle II as much as 77% of students who have achieved the criteria of completeness. The increase in the criteria for completeness can occur because the teacher provides interesting motivation so that students are more focused on participating in learning. Then, the teacher monitors the activities of students in groups and coordinates students to contribute to the group. In addition, it also provides additional time for presentation of the results of the discussion so that students can discuss again if there are differences of opinion. The results of this study indicate that the application of the Problem Based Learning learning model can improve the cognitive learning outcomes of students in class X MIPA-3 SMA N 1 Kembang.
