Abstract

This study explores the design of a Doppler effect experiment using a sound sensor on a smartphone. The main objective is to demonstrate that the change in sound frequency due to the relative motion between the source and the observer can be observed and measured using an easily accessible experimental setup. The experiment was conducted using a smartphone equipped with a sound sensor application to record frequency shifts from a moving sound source. The setup consists of a sound emitter with a constant frequency and either a moving observer or a moving source, making it easy to implement in educational settings. The results indicate that this experiment can effectively detect frequency changes. Data analysis shows an error rate ranging from 3.69% to 3.92%, proving that this method is sufficiently accurate for studying the Doppler effect. These findings highlight that integrating mobile technology into scientific experiments can be a valuable tool for educators, particularly in explaining wave phenomena such as the Doppler effect.

Abstract

Conceptual understanding is key to learning. It serves as the groundwork that enables students to apply concepts and build higher-order skills. However, previous studies have shown that students’ conceptual understanding of light waves remains limited, and comprehensive data across multiple regions are still lacking. This study investigates students’ conceptual understanding of light waves in West Java. The sample comprised 189 twelfth-grade students who had completed instruction on light waves, selected using a random sampling technique. Employing a survey design with a quantitative descriptive approach, data were analyzed using Rasch Model techniques. The instrument used was a 29-item multiple-choice Light Phenomena Conceptual Assessment (LPCA) which has been validated and reported as reliable. Based on person logit scores, results indicate that 58.73% of students fall into the low-ability category, 26.98% into the medium category, and 14.29% into the high category. These results indicate that majority of students have not yet attained an adequate level of conceptual understanding and still experience difficulties in understanding light wave concepts, which may limit their problem-solving abilities. These outcomes can inform educators and researchers in designing instructional strategies and learning media to more effectively teach light wave concepts and thereby improve students’ conceptual grasp.

Abstract

This study explores the efficiency level of two experimental methods for determining the coefficient of restitution, which have been widely conducted in previous research. Using smartphones as tools in physics experiments, the coefficient of restitution can be determined through visual analysis (camera) and sound sensors to detect collisions. Phyphox is used to record time intervals and the height of the ball after impact based on the sound of the collision with the floor. Additionally, Tracker is employed for visual motion analysis of the object during the collision. The coefficient of restitution calculated using Phyphox yielded a value of 0.894 ± 0.017, while Tracker provided a value of 0.888 ± 0.014. The results indicate by reviewing the percentage error between the two methods (0.715%), Phyphox and Tracker can provide accurate data for determining the coefficient of restitution, making them effective and efficient physics experiment-based learning tools in schools.

Abstract

This study proposes to examine the implementation of a science teacher training program for developing smartphone-assisted practicums, emphasizing the correspondence between expectations and program outcomes. This research depends on the substantial findings regarding the application of smartphones in scientific studies, which remain primarily theoretical and have not been extensively adopted by teachers in schools. The training program consists of three primary phases: self-assessment for science teachers, assessment of school laboratories, and a workshop focused on the utilization of smartphones in experiments. The results indicated that participants responded positively to the training, with the program's achievement level varying from "achieved" to "highly achieved." Educators evaluated the material as pertinent, practical, and capable of enhancing comprehension and proficiency in the design of novel experiments. The reflection results indicated a necessity for additional training on complex practical subjects, including Electricity, Magnetism, Thermodynamics, and Fluids, with instruction in the construction of student worksheets and smartphone sensor-based data analysis. This course connects research findings with educational practices and promotes the transformation of technology-enhanced science learning in schools.
