Abstract
The integration of multimedia lessons into science education has gained substantial momentum over the past two decades, driven by rapid advances in digital technology and an increasing recognition of varied student learning preferences. This manuscript examines the effectiveness of multimedia lessons—defined as instructional content combining text, images, audio, video, and interactive elements—in enhancing science learning outcomes among secondary school students. Drawing on foundational theories such as Mayer’s Cognitive Theory of Multimedia Learning and Sweller’s Cognitive Load Theory, this study employs a quantitative survey design to assess students’ conceptual understanding, retention, engagement, and self-efficacy in relation to multimedia-based instruction.
Data were collected from 450 students across six urban and rural schools, using a structured questionnaire measuring perceptions of multimedia lessons and self-reported learning gains. Statistical analyses, including descriptive statistics, correlation analysis, and multiple regression, reveal that multimedia lessons are positively associated with higher levels of conceptual mastery, engagement, and learner autonomy. Moreover, interactive simulations and animations emerged as particularly potent for illustrating abstract scientific concepts. However, limitations such as technological infrastructure disparities and teacher training gaps moderate these effects. The findings underscore the potential of well-designed multimedia lessons to foster deeper learning in science, offering practical implications for curriculum developers, teacher educators, and policymakers seeking to bridge the digital divide and advance 21st-century science pedagogy.
