Abstract

Physics learning on the topic of waves on a string at the senior high school level still faces various challenges, particularly in helping students understand abstract concepts such as amplitude, frequency, period, and wave speed. The limited use of interactive learning media causes students to be less active and less able to understand the material optimally. This activity aims to utilize student worksheets (LKPD) assisted by PhET Interactive Simulations in learning waves on a string for eleventh-grade senior high school students in order to improve students’ conceptual understanding and learning activeness. The implementation method was carried out through several stages, namely initial observation at the school to identify learning problems, preparation of LKPD assisted by interactive simulations, implementation of learning activities, and mentoring students during the activity. Data were obtained through students’ worksheet results, observations of learning activities, and activity documentation. The results showed that the utilization of LKPD assisted by Interactive Simulations helped students become more active in the learning process and facilitated their understanding of wave concepts on a string. In addition, students showed good enthusiasm during the use of simulations in physics learning. Therefore, the use of LKPD assisted by Interactive Simulations can serve as an effective alternative learning medium in supporting physics learning at the senior high school level.

Abstract

Learning difficulties in physics represent a prominent issue frequently encountered by high school students, particularly regarding topics requiring robust conceptual comprehension such as thermal expansion. This study aims to analyze the learning difficulties experienced by class XI students at SMA Negeri 4 Mataram in understanding the concepts of solid, liquid, and gas expansion. The research methodology employed is descriptive qualitative with a survey approach, utilizing a student perception questionnaire covering five main indicators: problem orientation, learning organization, conceptual investigation, development and presentation of results, as well as analysis and evaluation. The research respondents consisted of class XI students who had fully completed the topic of temperature and heat. Data analysis reveals that the highest percentage of learning difficulty is located within the conceptual investigation indicator, where students face significant hurdles in distinguishing between linear, areal, and volumetric expansion (83.3%) and explaining the underlying physical mechanism of dimension increases in solids when heated (75.0%). The primary factors driving these difficulties include the abstract nature of microscopic expansion, limited visualization of physical phenomena, and a weak contextual link between theoretical propositions and the surrounding environment. The implications underscore the urgent need for non-conventional, highly interactive instructional strategies that bypass rigid frameworks.
