PBL Model, Discussion Method, Discussion Approach, Varied Lectures, Video Learning Media & PPT to Increase Student Engagement.

Abstract

This research aims to develop and examine evectiveness audio visual which intergrede with Problem based learning model in improving cognitivenes student learning on the topic of uniform circular motion. This research use Research and Development (R&D) method with improving 4D model which conssist to the define, design, develop, dan disseminate. The study was conducted at SMPN 3 Kuala Kapuas with nineth grade students as a research subct. The data was collected through expert validation pretest and posttest, also lesarning outcomes. The validation result shows that the develop audio visual media obtained average 4,66 categorized is very good, , indicating that the media is feasible for use in learning. The effectiveness of the media was tested using gain score analysis and a t-test. The results showed that the use of PBL-assisted audio-visual media was able to improve students’ cognitive learning outcomes with a normalized gain value of 0.53, which falls into the medium category. In addition, the learning outcomes of the experimental class were higher than those of the control class, although the difference was not statistically significant. Therefore, the developed audio-visual media is effective as a support for problem-based learning and can help improve students’ conceptual understanding in physics learning.
