| Abstract: | Background: The Cognitive Theory of Multimedia Learning (CTML) has established fruitful principles to guide learners' attention and reduce their cognitive load. Although these principles have been shown to improve learning outcomes, it remains useful to examine learners' cognitive processes during learning using eye‐tracking techniques. Objectives: To mitigate cognitive load by segmenting content and directing the learner's attention to visual elements synchronised with auditory narration, we cumulatively presented visual segments within a single PowerPoint slide. We referred to this format as a cumulative presentation. Methods: Forty Japanese university students participated. They first completed a pre‐test to assess their prior knowledge, and subsequently viewed a biology lesson slideshow accompanied by teacher narration. In the cumulative presentation condition, visual elements were incrementally revealed alongside the narration, whereas in the whole‐slide presentation condition, all elements were presented simultaneously prior to narration. Throughout the session, we tracked the participants' eye movements. Following the lesson, all participants completed a post‐test identical to the pre‐test. Results and Conclusions: Learning outcomes were significantly higher in the cumulative presentation condition than in the whole‐slide presentation condition (Cohen's d = 0.49). Participants in the cumulative presentation condition fixated earlier on visual elements congruent with the teacher's lecture (d = 1.76) and for longer durations (Cohen's d = 1.15). These findings demonstrate the effectiveness of cumulative presentation in enhancing learning and visual attention, provide empirical support for the segmenting principle, and suggest practical implications for designing multimedia instructional materials. Summary: What is currently known about this topic? ○Segmenting multimedia materials into smaller units can reduce cognitive load and improve learning.○Guiding learners' gaze to relevant visual information corresponding to auditory content is known to be effective in improving learning outcomes.○Eye‐tracking can be used to examine how learners allocate attention during multimedia learning.What does this paper add? ○We introduced the cumulative presentation format, demonstrating the visual elements that match audio information cumulatively on the PowerPoint slide.○Learning outcomes of learners in cumulative presentation lessons improved compared to those in whole‐slide presentation lessons.○Eye‐tracking data showed that cumulative presentation guided learners' attention more rapidly and maintained attention on relevant information for longer periods.Implications for practice/or policy ○Instructors can improve multimedia lessons by progressively revealing visual elements rather than presenting all information simultaneously.○Even in continuous, instructor‐paced presentations, visual segmentation can support learners' attention and learning.○The findings provide practical guidance for designing more effective educational presentations.
