The Reconstruction Model of Science Learning based PhET-Problem Solving

This study investigates the effects of science learning model reconstruction based on student needs, in order to generate more operational standards and teaching materials. The conceptual understanding through virtual laboratory appears minimal, based on the analysis addressing the demands of junior high school students in several locations in Papua. Hence, there is a necessity to reform the learning structure through the utilization of physics education technology (PhET). Furthermore, the model was reconstructed by the Model Education of Reconstruction with fundamental principles, including an analysis of the education needs based on PhET-Problem solving, to compose context describing energy materials and its changes. Expert validation on the accuracy of illustrations, drawings, tasks, exercises, and questions, indicates the model is eligible. The participants are 60 students control and experiment group for junior high school public 11 Jayapura. The results showed the science learning model has demonstrated increased virtual experiment abilities and conceptual understanding trought pretest and postest based N-Gain. Analysis of data based normality test and independent test (T-test), meanwhile, there is a significant differences between experimental and control group. Outcome of students' responses for a separate learning model reflected positive.
