This research aims to the development of an e-module using Kodular software with a Problem-based Learning model on the momentum and impulse material. This study used the Research and Development method which is a research method used to produce a certain product and test the effectiveness of the product. The development procedure used a 4-D model. The 4-D model consists of 4 main stages, namely: Define, Design, Develop, and Disseminate. The data collection instrument used was a questionnaire given to the material expert and media expert to test the quality of e-module learning media using Kodular software with the Problem-based Learning model on momentum and impulse material. The final product produced has met the eligibility criteria with an average score of the assessment of material expert, 86,8%, media expert 84,8%, and education practitioner/teacher 87,2% in the highest feasible, category percentage for small group trial 86,8% and field trial 86,5%. The result of this research was an e-module with a Problem-Based Learning model that has been developed using Kodular software that accessible via smartphone.

This research aims to develop an active learning media in the form of Web-Enhanced Course. This research and development research follows the development steps of Borg & Gall. Data collection instruments used were validation sheets and questionnaires. The assessments’ average score for the feasibility of the product from the material experts is 84.83%, from media experts is 81.76%, and informatics experts are 83.61% in the very feasible category. Furthermore, the percentage of the results of small-group testing is 76.44% and for field-testing is 82.97%. Thus, the developed product is suitable to be used as a media for physics learning. The web is developed using the Problem-Based Learning (PBL) for the Basic Physics II subject

In physics learning a learning is needed which in addition to increasing understanding of concepts can also improve students' self-efficacy, one by one using the PBL model with scaffolding. With scaffolding, educators can provide assistance in stages to students who experience difficulties in learning. The purpose of this study was to determine the effects of PBL-based physics learning and scaffolding on understanding concepts and self efficacy. This type of research is the Quasy experiment using a non equivalent control group design. The research was conducted at one of the high schools in Bandar Lampung. The sampling technique is purposive sampling. The instrument used to measure understanding of the concept is a three-tier diagnostic test consisting of 10 questions, while the instrument for measuring self-efficacy is the observation sheet. From this study, the results showed that PBL-based physics learning with scaffolding was effective against the understanding of concepts and the self-efficacy of students. The value of the effect size obtained is 1.29 with a high category.Abstrak: Dalam pembelajaran fisika dibutuhkan suatu pembelajaran yang selain dapat meningkatkan pemahaman konsep juga dapat meningkatkan self efficacy peserta didik, salah satungan dengan menggunakan model PBL dengan scaffolding. Dengan scaffolding,  pendidik dapat memberikan bantuan secara bertahap kepada peserta didik yang mengalami kesulitan dalam pembelajaran.
