PENGEMBANGAN LEMBAR KERJA PESERTA DIDIK BERBASIS LABORATORIUM VIRTUAL PADA MATERI TEORI KINETIK GAS KELAS XI SMA

Abstract

Abstract:This study aims to produce valid virtual laboratory-based student
worksheets to be used as a medium for learning Physics in grade XI SMA on the kinetic
theory of gas materials. The type of research used is Research and Development (R&D)
with the ADDIE type of instructional media design model. In this study, three
experienced physics education lecturers are carried out in the validation stage. The
research instrument is a questionnaire in the form of a checklist. The aspects assessed
include aspects of content feasibility, presentation feasibility aspects, linguistic
feasibility aspects and graphic feasibility aspects. This study uses two types of data;
quantitative data is obtained from the score of the validator's assessment questionnaire
and qualitative one in the form of criticism and suggestions from the validator. The data
analysis technique in this study is descriptive analysis, by calculating the validity value
of each component of the student worksheet assessment using the Aiken's V coefficient
formula. The results show that virtual laboratory-based worksheets are declared valid
with Aiken's V coefficient value of 0.823 with very high category.
