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.

The aims of this development research were to produce a learning model for basic technique of squat-style long-jump based on biomechanics with the game for junior high school students and to know the effectiveness, efficiency and attractiveness against learning model. This research used Deff model adopted from Research & Development by Borg and Gall. The subject used was junior high school students which consists of 45 students. The instruments used were need analysis, expert’s evaluation, small and large group test. Effectiveness test was to know junior high school students’ jump skill level before being given biomechanic treatment. The Pre-test obtained from the students’ jump result was about 540, and Post-test was about 812. The conducted t-test between the experiment group and the control group obtained was t = 10.152 and in the n-gain score test between the experiment group (biomechanic treatment) obtained by 76% (effective) and the control group obtained by 43.40% (less effective). Therefore, this game model is effective in increasing students’ jump learning. According to the result, it could be inferred that: (1) this model can be developed and applied in physical education, (2) the model proved that there are significant difference in pre-test and post-test between the experiment group (biomechanic treatment) and the control group after the treatment model, based on N-gain test.

Character building becomes an essential part in the science learning process to prepare the students as the next generations of our nations. This study aims to develop a valid, practical, and effective learning model combined with indigenous science content for junior high school students in developing local wisdom-based characters and high-order thinking skills. This research is a a research and development (R & D) approach with the Borg and Gall model involving 36 junior high school science teachers (72 teachers). The research instrument were a character questionnaire as well as a test of problem-solving, critical and creative thinking tests, along with an assessment rubric to measure the depth of students' cognitive abilities. From the results of the learning model trial, it was found that there are eight characters based on Balinese local wisdom that can be developed in science learning for junior high school students namely religious, being honest (satyam), tolerance (tat twam asi), responsible (sesana/swadharma), curious, jengah, hardworking and generous, caring and friendly with nature. Conceptually, the core stages of the junior high school science learning model to develop Balinese local wisdom based characters include: initial exploration, investigation from various perspectives, elaboration, and confirmation and reinforcement. The stages in the science learning model that develop characters based on local wisdom provide opportunities for teachers to improve students' cognitive abilities, especially in the realm of higher-order thinking skills.

Junior high school students find it difficult to understand the materials and the concepts in science learning because the teaching method that is too monotonous. It is the lecturing method where students are less involved in learning activities, and this has led to the decline in students’ learning outcomes in science learning. The use of media and learning models play an important role. The popular media in learning are modern media, in this case PhET application. This application can give the impression of a direct experiment among students without ignoring technological developments where IT is needed by students. This study aims to identify students' conceptions on concepts. The type of this research was a library research. This study used the VAK learning model (Visual, Auditory, and Kinesthetic). In the VAK learning model, the teacher can combine three teaching-learning styles. 1) The teacher will prioritize the demonstration or the media by showing the teaching tools directly to the students and describing them on the board. 2) In learning by listening, the teacher must be able to explain clearly and in detail so that the students can understand the material presented. 3) In learning practice, after the students listen and learn through physical activity and direct involvement, they must conduct a direct experiment to gain deeper understanding of the materials. In this library research, the researchers searched for some references related to the research.

Problem representation in specific domains has raised great attention in the past years. In mainland China, research of the primitive physics problem teaching has been booming in the physics education domain recently. This study proposes six representations in the process of solving problems for middle school students, including abstraction representation, assignment representation, image representation, physics representation, methodology representation and mathematics representation. The measuring instrument of primitive physics problem for junior high school students was developed according to previous research and the principle of “Objectively Evaluating Subjective Questions”. The participants were 113 grade nine students in mainland China. The results of confirmatory factor analysis confirm the effectiveness of the measuring instrument. A weak correlation between the measuring instrument of primitive physics problems and Lawson Classroom Test of Scientific Reasoning (LCTSR) was found. Therefore, we believe that the primitive physics problem solving ability is a unique ability which is different from the general reasoning ability. This study demonstrates that using the measuring instrument of primitive physics problem to measure junior high school students’ ability of problem solving is promising.
