Using virtual science labs for physical science formal experiments in schools

Abstract

This study investigates the utilisation of virtual laboratories as a supplement to conventional laboratory settings for conducting formal science experiments. Although previous research acknowledges the growing integration of digital tools in science education, there remains limited empirical evidence comparing the effectiveness of virtual and traditional laboratory experiences in supporting conceptual understanding. Addressing this gap, the study aimed to examine whether virtual laboratory instruction enhances academic achievement in physical sciences to the same extent as traditional laboratory methods. A quasi-experimental design was employed using pre- and post-test achievement scores, and the treatment involved conducting an acid-base titration activity through a virtual laboratory. The participants consisted of two hundred and eleven grade eleven physical science learners selected through random sampling. Data were analysed using independent t-tests and analysis of variance. The findings indicate that the type of experimental environment influences learner performance, yet no meaningful difference was found between virtual and traditional laboratory groups. Both approaches contributed similarly to improved conceptual comprehension. The study implies that virtual laboratories can serve as viable alternatives where conventional facilities are limited, supporting flexible and accessible science instruction.
