Assessing conceptual understanding of learning in energy and momentum by using Socrative online polling in physics classes

Abstract

This research investigates the understanding and learning gains of students learning between online and onsite classes on topics of Energy and Momentum. In this study, twenty-five questions relating to Energy and Momentum, including Energy Concepts, Work Done by Gravitational Forces, Work Done by Nonconservative Forces, Conservation of Mechanical Energy, Momentum Concepts, Momentum Conservation, Completely Inelastic Collisions, and Applications of the Impulse-Momentum Theorem, were used. One hundred and ninety-five students from the Faculty of Engineering at Rajamangala University of Technology Lanna, Chiang Mai campus, were tested through online and onsite learning between 2021 and 2022, respectively. The collected data were evaluated using Socrative online polls. Statistics, including average percentage, standard deviation, and the normalized gain method, were used to analyze the understanding of learning between the pre-test and post-test of online and onsite classes. The results found that after classes, the mean of correct answers for online classes was 18.76 (SD = 2.81) and 20.68 (SD = 3.19) for onsite classes. The average normalized gain <g> for online classes was 0.01, and for onsite classes was 0.05. These results demonstrated that onsite learning was more effective than online learning.
