<![CDATA[A problem-based learning model is a learning model that introduces learning from phenomena faced by students so that students can understand contextually and improve their cognitive abilities. This study aims to improve students' cognitive learning outcomes using Problem-Based Learning (PBL). The type of research used is the analysis of class action research descriptions. This research design uses the Kurt Lewin model. The subject of this study took class VIII-H, which consisted of 32 students at SMP Negeri 3 Bangil. Data collection techniques used were pretest and posttest. Data were analyzed descriptively and presented in tabular form. The results showed an increase in students' cognitive learning outcomes; in cycle one, it was 62% with an average score of 78.75; in cycle two, it increased to 90% with an average score of 86.71. This means an increase in cognitive learning outcomes. Thus, using the Problem-Based Learning (PBL) learning model on digestive system material can improve the cognitive learning outcomes of class VIII students of SMPN 3 Bangil.]]>
