The Effect of The Use of Harmonic Movement PhET Interactive Simulation in Online Learning Process on Mastering the Concept of High School Students

Abstract

This research aimed to determine the effect of using the PhET Interactive Simulation in the online learning to the conceptual mastery ability of high school students. The method used in this research was an experimental method with the one group pretest posttest research design. The research sample was selected using purposive sampling technique from a population of the Science and Mathematics Group Students of Public High School (SMAN) 1, Jakarta. The research instrument used was an objective test of students’ mastery of concepts that had been tested for validity, reliability, difficulty level, and distinguishing power. Based on the results of data processing, the average of pretest and posttest scores were 47.42 and 73.55, respectively, and the N-gain of 0.51 with the medium category. The analysis result shown that count (10.909) was larger than table (2.042) which indicated that the null hypothesis (H0) was rejected and the alternative hypothesis (HA) was accepted. Meanwhile, the strength of the effect of using the PhET simulation in the Online Learning Process to Mastery the Concept of Harmonic Motion for High School Students on a numeric scale was categorized high with an effect size value of 1.79. Thus, it can be concluded that the PhET simulation can be applied to mastery of the physics concept of Harmonic Motion in the online learning process of high school students.

Online and Distance Learning Research in The Last 30 Years: Real Contribution in Physics Learning

“…It can be seen from Table 6 and with the majority of students in the 21st century are proficient in advanced technology and are adaptable. For example, online learning with interactive simulations positively affects student physics learning outcomes (Sunaryo et al, 2021). In addition, the use of interactive modules is also very important to apply because, according to research (Roza et al, 2021), online learning of physics with interactive modules shows compatibility and a positive impact.…”
