Abstract

This study aims to develop a valid and practical Arduino Uno-assisted free fall experiment tool as a learning medium for 11th grade high school/MA physics. It uses the research and development method with the ADDIE model, which includes the stages of analysis, design, development, implementation, and evaluation. The research subjects consisted of three expert validators and grade XI high school students as limited test subjects. The practical tool was developed by integrating Arduino Uno, infrared sensors, ultrasonic sensors, HC-05 Bluetooth modules, and MicroSD modules to support automatic time and height measurements, wireless data transmission, and digital storage of experimental data. Data collection was carried out using expert validation sheets and student practicality questionnaires, then analyzed using validity and practicality percentages based on predetermined criteria. The results of the study show that the developed laboratory equipment has a very high level of validity with an average percentage of 88% (very valid category) and a level of practicality of 81.5% (very practical category). These findings indicate that the practical tool is suitable for use as a physics learning medium and is capable of improving the quality of practical activities through more accurate measurements, time efficiency, and more systematic management of experimental data. Unlike previous studies, which generally focused on technical aspects in a partial manner, this study emphasizes the integration of measurement systems, data transmission, and digital data management in a single learning device.

Abstract

The low engagement of tenth-grade students at SMAN 2 Padang Panjang in conventional teaching methods often results in passive participation during the learning process. Consequently, the learning outcomes of some students tend to be below the Minimum Mastery Criteria. This research was conducted to determine the effect of the Jigsaw cooperative learning model in enhancing the activeness and learning outcomes of tenth-grade students at SMAN 2 Padang Panjang. The method used was a quantitative approach with a quasi-experimental design and a posttest-only control group design. This study was conducted with a population of tenth-grade students consisting of 9 classes. The sample were class XE.2 (experimental group) and class XE.4 (control group), selected through random sampling. The research instruments consisted of an observation sheet for learning activeness and a posttest for learning outcomes. The results indicated that the Jigsaw cooperative learning model positively contributed to student activeness. Student engagement in the experimental group improved across all indicators, with the average percentage of activity 87%, compared to control class which only 56%. The perspective of learning outcomes shows the average posttest score of the experimental group was 86.13, with a completion rate of 90%. This result significantly differed from the control group, the average score of 77.12 with a completion rate of 59.38%. Statistical analysis using the Mann-Whitney U test shows a p-value is 0.0139 (p<0.05), indicating a significant difference between the two groups. In conclusion, the Jigsaw cooperative learning model has a significant effect on enhancing student activeness and learning outcomes.
