USING PHET SIMULATIONS TO IMPROVE STUDENTS' REPRESENTATION ABILITY ON THE TOPIC OF CHEMICAL REACTIONS

Abstract

This research aims to determine whether there is an increase in students' representation abilities after using PhET Simulations on the topic of chemical reactions. This type of research was quasi-experimental using a pretest and posttest control group design. This research involved two groups of students, namely the experimental group using PhET Simulations during the learning process while the control group only used conventional worksheets. The data collection technique used a 25-item test that refers to indicators of representational ability. This hypothesis test uses the t-test (Independent Sample t-Test) using the assumption that the data is normally distributed and homogeneous. The results of the analysis show that there was an influence of using PhET Simulation in improving students' representation abilities at MA Al-Hikmah as evidenced by the sig (2-tailed) value of 0.000 < 0,05 so that H0 is rejected with the n-Gain value in the experimental class of 0.71 which is in the high category.
