PENGEMBANGAN LEMBAR KERJA SISWA PADA MATERI POKOK BAHASAN GELOMBANG BERJALAN DAN GELOMBANG STASIONER BERBANTUAN LABORATORIUM VIRTUAL PHYSICS EDUCATION TECNOLOGY

Abstract

Student worksheets (LKS) are one of the appropriate learning alternatives for students because they can help students to add information about the concepts learned through the process of learning activities. This study aims to develop a worksheet based on a virtual physics education technology (PhET) laboratory on the material of traveling waves and stationary waves. This research was conducted at the state 42 Jakarta Senior High School (SMA) in class XI Mathematics and Natural Sciences (MIPA) in the even semester of the 2020/2021 academic year. This research uses a research and development (R& D) method with simple random sampling. Validation was carried out for the subject matter, learning media and language used of the LKS developed. At the end of LKS development was the implementation of the LKS, a questionnaire was distributed to students to determine student responses to the developed LKS. The results of the validation of the subject matter, learning media and language obtained an average value of 81.09%, 76.96% and 82.50% with feasible, feasible, and very feasible categories for each validation carried out. While the results of student responses showed an average value of 87.39% with a very positive category.
