Abstract

AbstractThe background to this research is that physics lessons are often considered difficult and less interesting by students, especially because of their abstract nature, the complexity of mathematical calculations, and the difficulty in connecting theory with practice. One of the challenging topics is Newton's Law of motion, which includes the relationship between force, mass and acceleration. This research was carried out at MA Muallimin UNIVA Medan, by applying the Problem Based Learning (PBL) learning model, an innovative learning media that is relevant to development. technology. This research utilizes PHET (Physics Education Technology), an interactive simulation platform developed by the University of Colorado Boulder, to support learning Newton's Laws. PHET allows students to carry out virtual experiments independently with various variables, such as mass, force and surface type, so that student learning outcomes increase. The research method used is quantitative in class X-G. The instrument used is a written test (essay) with a total of 10 questions. It is known that the pretest and posttest data are normally distributed with a significance value of Pretest (0), Posttest (0,), and are declared homogeneous with a significance value Based on Mean (0.245) where the normality and homogeneity test values exceed (>) the real level used in the measurement namely α = 0.05 or 5%. With the help of SPSS, it is known that the average posttest student learning outcomes (85.93) are higher than the pretest (58.80), so it can be concluded that the hypothesis is accepted.

Abstract

Teaching materials play an essential role in education, serving as critical resources and guides for both teachers and students. They significantly enhance students' understanding and competency development by aligning with curriculum demands, particularly skill-based competencies. Science process skills are vital for engaging students in Physics, yet traditional teaching methods often limit the development of these skills. Effective Physics education should incorporate diverse strategies, including the case study approach, which fosters scientific thinking, creativity, and problem-solving skills. Implementing a scientific approach can further enhance these skills but may present challenges such as reduced learning pace and student interest. Teachers must address these challenges through close monitoring and thorough preparation, ensuring teaching materials are valid and effective. Researchers propose integrating case-based methods with a scientific approach to aid students in learning wave phenomena, making Physics concepts more accessible. The effectiveness of these materials will be evaluated using the N-Gain test, a statistical measure assessing improvement in student performance through a quasi-experimental pretest-posttest design, with data analyzed using SPSS. This study aims to identify issues and gather user feedback to optimize Physics teaching materials. The analysis of teaching materials developed using the case method, supported by a scientific approach, reveals their effectiveness in enhancing students' science process skills. The average N-Gain score of 0.71, reflects a 71% improvement, these materials significantly improve students' abilities, particularly in the Sound Wave subject. The effectiveness is evident in the enhanced skills of analysis and problem-solving among students, validated through pre-test and post-test comparisons. The average pre-test score was 60.4, which increased to 88.3 in the post-test. Despite some challenges such as inconsistent internet access, the teaching materials proved to be highly effective, with 20 students achieving effective results and 10 achieving fairly effective results. The teaching materials also foster various science process skills including critical thinking, experimentation, and communication. These methods encourage student engagement, critical thinking, collaboration, real-world application, creativity, and overcoming learning barriers, making education more dynamic and interactive.

Abstract

Background: Student learning outcomes in the topic of Energy and Its Transformations remain consistently low in Indonesian vocational high schools. One of the key challenges is the predominant use of conventional teaching methods and the minimal use of engaging digital tools. This results in low student participation and limited conceptual understanding.Aims: This study aimed to develop and evaluate interactive learning media using Canva, integrated with the Project-Based Learning (PjBL) model, to improve student engagement and learning outcomes in IPAS (Natural and Social Sciences) for Grade X students.Methods: The study employed a Research and Development (R&D) approach using the ADDIE model, covering Analysis, Design, Development, Implementation, and Evaluation. The media included interactive features such as visual simulations, drag-and-drop tasks, embedded videos, and quizzes with instant feedback. It was validated by three subject-matter experts and tested in stages: individual trials (3 students), small-group trials (6 students), and a field test with 64 students divided into experimental and control groups. Instruments included expert validation sheets, practicality questionnaires, pretest and posttest assessments. Data were analyzed using descriptive statistics and independent t-tests.Results: The media received a validation score of 88.7% (highly feasible). Practicality ratings from teachers and students averaged 89.4%. The experimental group showed significantly higher posttest scores than the control group (p < 0.05), with moderate learning gains.Conclusion: Canva-based interactive media, when combined with the PjBL model, is valid, practical, and effective for enhancing engagement and learning outcomes in vocational science education. It is suitable for broader implementation across similar educational settings.
