Abstract

In order to survive and improve self quality in higher levels of education and work, generic science skills are needed. Generic science skill is the skill that can be grown from science learning as a provision to pursue careers in a broader field. In this day and age, many things can be done by using devices, including physics learning. This study aims to find out the differences of generic science skills improvement between a class that apply solar system learning with a scientific approach assisted by Solar System Scope with a class that do not use Solar System Scope. The method used in this study was quasi-experiment with the control group pretest-posttest design. The sample consisted of 31 experimental class students and 31 control class students in the junior high school in Bandung. Both classes were given the multiple choice test. The results of data analysis showed an improvement in both classes with N-gain 45.9% in the experimental class and 22.8% in the control class. The conclusion of this study can be showed by Mann Whitney hypothesis test which produces z = -3.60. It shows that there is a significant differences of generic science skills improvement between both classes after the implementation of solar system learning assisted by Solar System Scope.

Abstract

The problem-solving skills of Indonesian students are still relatively low, especially in complex subjects like Newton's law in Physics. Therefore, a learning Media is needed to improve these skills, such as the Tournament-based Truth or Dare Online Card (New Todame) to enhance problem-solving abilities, specifically on Newton's law. This study aims to: (1) gather information about media needs from teachers and students, (2) develop New Todame media, (3) assess the feasibility of the media, (4) gather feedback on user satisfaction, and (5) examine the improvement in problem-solving skills after using the New Todame media. This research is development research (R&D) using the ADDIE design, consisting of Analysis, Design, Development, Implementation, and Evaluation stages. Data collection was done through interviews, preliminary study questionnaires, validation sheets, feasibility questionnaires, and pretest & posttest sheets. The results indicate that New Todame is feasible for use, and there is an improvement in problem-solving skills on Newton's law after using the New Todame media, with an N-Gain score of 0.455, categorized as moderate.

Abstract

This study aims to design and implement a motion experiment using a smartphone’s light sensor, powered by the Phyphox application, to investigate uniformly accelerated linear motion. A dynamic cart equipped with a smartphone was released along a rail inclined at 1°, with an LED strip serving as the light source. The smartphone's light sensor recorded variations in light intensity as the cart moved, allowing for the determination of acceleration over time. Data analysis focused on the relationship between acceleration and motion, demonstrating consistent acceleration values ranging from 0.127 m/s² to 0.128 m/s² across multiple trials. The LED setup was adjusted to optimize data collection, ensuring the reliability of measurements. These results confirm the theoretical principles of uniformly accelerated motion and highlight the effectiveness of smartphone-based sensors for experimental and educational applications. Despite a percentage error of approximately 25% when compared to theoretical calculations, the small standard deviation value of 0.000242 indicates a high level of precision and repeatability in the experimental results. This suggests that the experiment, although not perfectly accurate, can still serve as a reliable instructional tool in physics classrooms. The experimental design is not only low-cost and portable but also adaptable to different learning environments, making it a suitable alternative when conventional lab tools are unavailable. Future research could explore alternative sensor configurations or extended applications in physics education. Additionally, improvements in the light sensor’s sensitivity, optimizing the distance between light sources, and using more mobile supporting structures are recommended to increase data accuracy and ease of implementation in physics experiments for students studying linear motion.     Keywords: inclined plane; light sensor; linear motion; lux meter; phyphox.
