Application of e-handout with Schoology-based PhET simulations to improve students’ visual representation ability on optical material

Abstract

This research is pre-experimental and has a purpose to improve students' visual representation ability through the application of e-handouts with schoology-based PhET simulations on optical material. Sub material taken is lenses and optical devices. One group pre-test post-test was designed in this research with samples were selected by the technique of cluster random sampling. XI MIA 3 class was sample as the implementation class and XI MIA 5 was sample as a modeling class at SMA Negeri 1 Sleman, Yogyakarta. The samples consist of 55 students. The essay test of eligibility results by expert judgment was used in this research. The research result is the application of e-handouts with Schoology-based PhET simulations can improve students' visual representation ability and include in the medium category for both classes.
