Application of the Virtual Laboratory Assisted Inquiry Learning Model for Understanding the Concept of Light Theory and Optical Instruments for Class VIII Students of SMPN 24 Bekasi

Abstract

Light material and optical equipment are materials that have conceptual and procedural characteristics so that they require practical activities, but this practicum is still rarely carried out due to the limitations of laboratory equipment and materials, the availability of school facilities and infrastructure that are not adequate In the learning process the teacher uses learning media, namely power points and learning videos that are delivered using the lecture method. This study aims to determine the effect of the application of the guided inquiry learning model assisted by the Virtual Laboratory on the understanding of the concept of light material and optical instruments for class VIII SMPN 24 Bekasi. To identify these problems, researchers using a quasi-experimental method (quasi-experimental), with a nonequivalent control group design. This study obtained the result that the guided inquiry learning model with the help of virtual laboratory media had an effect on increasing the ability to understand the concept of light and optical instruments. This is indicated by a significant increase in students' ability to understand science concepts, oral communication, collaboration, and problem-solving after following the guided inquiry learning process with the help of virtual laboratory media with an average of 8.49 in the experimental class while in the control class 7.91.
