Abstract

This research focuses on the development of learning media to teach vector concepts to improve students' understanding of vector addition, vector projection, and dot product calculations. This research uses a Research and Development (R&D) approach, which involves media design using Corel Draw and CNC technology for acrylic material fabrication. Validation was conducted by subject matter experts and media specialists to ensure the accuracy and interactivity of the content, while field trials tested the effectiveness of the media with high school students. The results showed that the learning media achieved an accuracy level of 0.17% in the parallelogram method, 0.60% in component analysis, and 0.83% in dot product projection, indicating high precision in visualizing the magnitude and direction of vectors. Validation feedback rated the content, conceptual alignment, design, and interactivity as good to excellent, with an average score of 80-92%. Therefore, this learning tool is considered effective and useful in helping students overcome difficulties in mastering vector concepts.

Abstract

This classroom action research aims to enhance students’ science process skills (SPS) in Class VIIIA of SMP Negeri 127 Jakarta through the experimental method. Observations indicated low SPS due to teacher-centered learning. Conducted over three cycles, the stages of experimental method are problem identification, hypothesis formulation, experiment design, data collection, analysis, and conclusion. Results showed an increase in the average SPS score from 64 (cycle I) to 82 (cycle III) based observations, supported by worksheet analysis. This Research concludes that the experimental method effectively improves students’ science process skills in learning the topic of Energy.
