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.

This study aims to determine the effect of Conventional Model and the Missouri Mathematics Project (MMP) learning Model with self-concept on mathematical problem- solving abilities of junior high school students. The design of this study was experimental and control group post-test design. The method used is the quasi-experimental method using treatment by level 2x2 design. The experimental class was given the MMP learning model treatment while the control class was treated with conventional model. The samples of this study were 48 seventh grade students. The instruments used were self-concept questionnaires and a test of mathematical problem-solving abilities.Technique of analysis used was two-ways ANOVA. The results of this study show that the MMP learning model has a syntax that is able to empower mathematical problem-solving abilities compared to conventional learning model. Students who have a positive self-concept or students who have a negative self-concept are more suitable to be treated with the MMP learning model than conventional learning model.

This study aims to describe the effectiveness of the application of the jigsaw model in learning to write Indonesian exposition texts for class VIII SMP Negeri 4 Sendana in Majene. The type of research used is a quasi-experimental type experiment with two groups, namely the control group and the experimental group who were given a pretest and posttest. These two groups aim to prove whether the jigsaw learning model is effectively used or not in class VIII of SMP Negeri 4 Sendana. The results of the study suggest that Jigsaw Model is less successful, as shown by the 17 pupils who can only answer the questions that have been presented. As demonstrated by 51 students who were able to answer questions, the outcomes of studying exposition texts using the jigsaw learning approach in class VIII were successful.
