Home-Made Simple Experiment to Measure Sound Intensity using Smartphones

The researchers present a simple experimental activity to measure the sound intensity level using an Android-based smartphone to prove the inverse square law and analyze the dependence of the sound intensity to the sound source frequency. The type of this study was quantitative research by conducting level of intensity experiment using a pair of smartphones with one smartphone functioning as the sound source using a tone generator free application (app) and the other smartphone functioning as the detector installed with Physics Toolbox sound meter application to measure the arriving sound intensity level. The smartphone functioning as the sound source was placed at a certain place labeled as the origin point (0.0), while the other smartphone as the detector was placed at various distances on the x-axis. In this study, the frequencies of the tone generator used were 500 Hz, 1000 Hz, and 2000 Hz. Then, the sound intensity level versus distance was analyzed to determine the compatibility between the experimental results using a smartphone and the prevailing theory, namely the inverse square model. The sound intensity level detected by the smartphone from 2,000 Hz resulted in the graph with smaller slope after passing 0.3 meters. The results follow the theorem of which the sound intensity level at the detector depends on the distance between the source and the detector based on the inverse square law. When the frequency of a source was changed (500 Hz, 1000 Hz and 2000), the sound intensity also changed. Higher frequency leads to a larger sound intensity. The experiment can thus be used to assist  high school students and physics undergraduates in understanding the inverse square law of sound or to study environmental noise with a simple and low-cost experiment

The results showed the implementation of the scientific approach to learning and the improvement of cognitive learning outcomes of students in the classroom using hand-on in the form of KIT media is better than the PhET simulation. It can be concluded that learning a scientific approach that uses hand-on in the form of KIT media is better than a PhET simulation. Both in implementation and in improving students' cognitive outcomes in harmonic oscillation. Thus, the use of KIT media and PhET simulations can be implemented to improve student cognitive learning outcomes on other physics topics.

Implementation of Online Think Pairs Share (OTPS) Model to Improve Student Learning Outcome

This study was an online classroom action research (PTK) due to the COVID-19 pandemic. This study aimed to improve learning outcomes in calculus classes for physics engineering students using think pairs share. The online think pairs share (OTPS) learning model was optimized using the Learning Management System (LMS) platform in two learning cycles. The research sample was 46 students in the study program of physics engineering. The data were obtained from the pre-test-post-test scores, group discussions, and individual presentations. The results showed that the pre-test and post-test scores in cycle I were 37.16 and 68.41, while in cycle II, 41.20 and 68.65, respectively. In addition, the daily student score from the group discussion and individual presentation was 60.68 for the cycle I and 60.15 for cycle II. Furthermore, inferential analysis using the Kolmogorov-Smirnov test proves that tcount > ttable. Hence, the result indicated that implementing the OTPS learning model optimized using LMS could improve the student learning outcomes in calculus
