Prototype of Physic Lessons Based on Microcontroller to Increase Students? Conceptual Understanding

One of the efforts to increase students conceptual understanding in physics lessons is to utilize various learning media as tools of learning aid. This research aims to develop prototype of lessons that are accurate, valid, effective and practical as learning media in order to optimize conceptual understanding regarding rotational movement of rigid object. The prototype of physics lessons that have been developed are props based on microcontroller, lesson modules, Students Exercise, Practical Guides, Lesson Plan, and various tests. The prototype itself has been cultivated using Research and Development Method through the ADDIE approach. Test of Effectiveness of the prototype was conducted through a pre-experimental design one group pretest-posttest which involved students of the physics department of STKIP SoE. Data gathering was completed through validation paper, observation, tests and surveys. Results of validation tests through expert tests shows that the prototype has been developed in highly valid category. Research results show that the prototype positively influences students conceptual understanding. Trial for effectiveness through the N-gain test shows an increase in conceptual understanding in low category. Whereas practical test shows that the developed prototype lessons are very practical to utilize as a learning media.
