ABSTRACT
This study is the development of problem-based learning-based science teaching materials that are assisted by audio-visual media in an effort to improve students' critical thinking skills in Grade V. The purpose of this study was to analyze the feasibility and effectiveness of problem-based teaching materials based on problem-based learning assisted audio-visual media on organ motion material in animals and humans. The method used in this study is Research and Development (R&D) with model Analyze, Design, Development, Implementation, Evaluation (ADDIE). SDN Kebon Pelok and SDN Kanggraksan Cirebon became the subject of research. There are two Tests, limited scale test with 15 students and large scale test with 30 students. The results of the material expert validation test 74.75 with good enough categories and the media expert test 89.50 including very good categories. Analysis of normality test results 0.103>0.05 means normal data, homogeneity Test 0.585>0.05 means homogeneous data, t test 0.000 < 0.05 means significant changes after the action and N-Gain score of 0.5478 is in the range of values between 0.3 to 0.7, which means in the medium category.
Keywords: Problem-Based Learning, Audio Visual, Critical Thinking Skills
