Publication Open Access Effectiveness Of Multimedia Projector-Based Instructional Methods In Enhancing Students’ Learning Of Science(Faculty of Humanities and Sciences, SLIIT, 2023-11-01) Madushani, U.V.S; Perera, K.G.S.K.Multimedia-based instructional strategies play an important role in enhancing students’ performance as well as students’ motivation towards the learning of science. The aim of this study was to determine the effectiveness of the use of multimedia projectors in enhancing students’ learning of science and students’ motivation towards multimedia in learning vs traditional chalk-and-board method. A quasi-experimental research design was used to investigate the performance and motivational effect of the usage of multimedia projector. A convenient sample of 30 students in grade eight was used in this study. The experimental group of 15 students were taught using a multimedia projector and the control group of 15 students were taught the same science lessons using traditional chalk and board method. Students’ performance was evaluated using a pretest and a post-test. The motivational scale based on the Keller’s ARCS model of motivation was administered on the experimental group to study the degree of motivation displayed in the use of the multimedia projector for instruction. The findings of this study supported the hypothesis that the use of multimedia-based instruction is more effective than the traditional methods in students’ learning of science. Further, it was found that the students’ motivation was also high in the use of the multimedia projector to teach science.
