THE DEVELOPMENT OF STUDENT WORKSHEETS WITH A SCIENTIFIC APPROACH BASED ON THE VIRTUAL LABORATORY

Abstract

This study aims to develop student worksheets with a scientific approach based on a feasible PhET virtual laboratory and to find student responses. With the Scientific Approach, students will be directly involved or have experience with objects and stimuli in the learning environment. This study uses three virtual, namely pHet, Maya Laboratory and Olabs Amrita.The research was conducted at the Department of Physics, State University of Medan. This type of research uses the Research and Development (R&D) Borg and Gall model. The resulting product is a Student Worksheet that will be applied to partners, namely class D 2022 students who take the General Physics course. The data analysis technique used qualitative and quantitative data analysis techniques by describing the feasibility, response, and effectiveness of student worksheets on a scientific approach. Data collection tools in this study were a questionnaire, observation, and documentation. The results of this study indicate that: 1) This student worksheet is very feasible to use based on the results of the percentage score of the material expert assessment of 88.3% and the percentage score of the media expert 86.67 % (2) a very good response, based on the percentage results the response score of the small group student reviewers was 89.65% and the percentage of the response scores from the large group student reviewers was 90.01% (3 The student test results with an average score of 45.56 for the pretest results, and the total average score for the posttest results were 85.31.Then obtained an N-gain score of 0.75 with a high category and an N-gain score (%) 75% with an effective interpretation .Then obtained from the assessment questionnaire and responses, it can be concluded that the student worksheets with the virtual laboratory-based Scientific approach are very feasible to use and develop
