Development of Learning Media of Microscope Portable Auto Design to Increase Student's Problem-Solving Ability in Light and Optical Tools Topic

摘要

This study aims to evaluate the effectiveness of developed learning media in the form of digital portable auto design microscopes to improve student's problem-solving abilities. This research used a research and development method. The subjects of this study were students of grade VIII at one of private junior high school in Mataram. The main products includes portable digital auto design microscopes and supporting devices in the form of syllabus, lesson plan, worksheet, and instruments of problem-solving abilities developed with learning models of Problem Based Learning. To find out the effectiveness of the product, the data of student's problem-solving ability was then analyzed using the N-Gain equation. The results showed that the portable digital microscope auto design is very effective for problem-solving capabilities with a gain value of 0.71.
