Subject Specific Pedagogy Development with Scaffolding Approach Assisted by PhET Simulation on Momentum Conservation Law to Improve Students’ Conceptual Understanding and Learning Independence

Abstract

SSP of physics has been produced with scaffolding approach assisted by PhET simulations on law of momentum conservation to improve the conceptual understanding and the learning independence of high school students. This research uses 4-D development model. the subject in this research is the students of MAN 1 Yogyakarta class X MIPA 3. Instrument data collection in the form of expert validation sheets, learning independence observation sheets, and conceptual understanding test questions. Research data was collected through observation sheets, and written tests consisting of 10 pretest questions and 10 posttest questions. The data obtained is then analyzed descriptively. The results showed that (1) the development of SSP of physics was carried out in accordance with product development procedures. (2) the results of expert validation indicate that the SSP of physics has very good category. (3) There is no significant difference between students’ conceptual understanding before and after learning using SSP of physics with scaffolding approach assisted by PhET simulation. (4) Learning independence of students is in the category of good enough and good after learning to use SSP of physics with scaffolding approach assisted by PhET simulation. These results indicate that the SSP of physics is suitable for use as teaching material.
