The Effectiveness of Kinematics Worksheets Based Instructions Virtual Phenomenon to Improve Science Process Skills and Conceptual Understanding of Pre-Service Physics Teachers during the COVID-19 Pandemic

ABSTRACT

Science process skills and conceptual understanding of pre-service physics teachers were in the low category. This research was conducted to solve this problem by using worksheets based on virtual phenomenon instructions. This research aims to determine the effectiveness of worksheets and improvement of science process skills and understanding of concepts in pre-service physics teachers during the COVID-19 pandemic. The design of this research is one group pretest-postest with purposive sampling are pre-service physics teachers who take mechanics course in the academic year 2020/2021 (n = 81) consists of 21 males and 60 females. There are 6 conceptual understanding questions for pretest and posttests based on Bloom's Taxonomy (C2, C3, C4). Assessment of science process skills includes indicators of observing, classifying, interpreting, predicting and communicating consist of 5 questions. The data analysis technique uses the effect size and N-Gain score. Based on the result of this research, it was found that the improvement of science process skills and conceptual understanding of pre-service physics teachers reached 0.56 and 0.47 which was categorized as moderate. Effect size for science process skills and conceptual understanding are 3.5 and 1.9 are categorized very high so it can be concluded that the effectiveness of kinematics worksheets-based instruction virtual phenomenon is very significant to improve science process skills and conceptual understanding of pre-service physics teachers. © 2022 American Institute of Physics Inc..
