Abstract

This study aims to determine the comparison of students 'mathematical representation ability through the Project Based Learning (PjBL) Model and the students' mathematical representation ability through the conventional model. The PjBL model is a student-centered, innovative, project-based learning model and positioned teachers as effective facilitators in the contextual learning related to real life situation. This research employed quasi-experimental design. The research applied the posttest only non-equivalent control group design through randomized cluster sampling. The data collection technique used was test. The instrument used to collect the data was the essay test. Data analysis was conducted using independent sample t-test. The result of the data calculation through the Independent-Sample T-Test test obtained the significance level of 0.913 means that the students’ mathematical representation ability was better after the learning through Project Based Learning (PjBL) model was conducted compared to the students' mathematical representation ability through a conventional model. This means that the PjBL model is more influential on students' mathematical representation ability.

Abstract

This research and development aims to determine the feasibility, attractiveness of student responses, and the effectiveness of the development of videoscribe sparkol-based bilingual learning media. The type of research in this development is (Research and Development). The development model used is the ADDIE model with five research steps; Analysis (Analyze), planning (Design), development (Development), Implementation (Implementation), and Evaluation (Evaluation). Data collection techniques using questionnaire sheets and tests. The instrument used was in the form of a questionnaire to determine the feasibility and attractiveness of students' responses, as well as tests to determine the effectiveness of the products developed. Data analysis techniques used are quantitative descriptive and qualitative descriptive. Obtained the results of the average feasibility test for learning media by media experts, material experts, and linguists with a "very good (SB)". The results of the average attractiveness test on the response of students with the criteria "very good (SB)". It can be concluded that the product development of the generated videocribe sparkol bilingual learning media is feasible, interesting, and effective by providing good results in its implementation.
