Implementation of PDEODE (Predict, Discuss, Explain,Observe, Discuss, Explain) Supported by PhET Simulation on Solubility Equilibrium Material

Abstract

This study aims at describing students’ activities, analyzing students’ learning outcomes at each stage of PDEODE learning supported by PhET simulation, and analyzing students’ learning outcomes after PDEODE learning supported by PhET simulations. The method used is classroom research with one-shot case study research design. The subject of this study consists of 37 students from class XI IPA 1 of SMAN 1 Rengasdengklok - West Java. The instrument used was in the form of observation sheets of the activities of both researchers and students, worksheet, and higher-order thinking skill test. The results of this study show that students’ activities are included in the very good category with an average percentage of 93%. Student learning outcomes ability at each stage of PDEODE learning supported by the PhET simulation on solubility equilibrium material obtain an average value of 91, and the highest average value was at the prediction stage with the indicator of analyzing and at the observation stage with the indicator of creating and analyzing with an average value of 95 while the lowest value was at the final discussion stage with the indicator of analyzing and evaluating with an average value of 83. The higher-order thinking skill of students after PDEODE learning improves with an average value of 89 included in the very good category. High, medium, and low groups achieve very good average values of 91, 89, and 87 respectively. Thus the implementation of PDEODE supported by PhET simulation can improve students’ higher-order thinking skill.
