Slideware applications (e.g., PowerPoint) have become more prevalent in instruction across disciplines. This is especially true at post secondary institutions where many instructors are using slideware as a sole instructional tool. This study evaluated the relative effectiveness of scientific visualization in two PowerPoint delivery strategies on science learning for preservice teachers. Twenty-five preservice teachers enrolled in an undergraduate introduction to science education class were stratified into two PowerPoint delivery strategies. The strategies were: PowerPoint with instructor voiceover narration and PowerPoint without voiceover. Post-test Mann-Whitney U suggested no differences (p greater than 0.05) in science learning across the two strategies. Further, eye tracking analysis suggests voiceover guides the PowerPoint user to graphics and text, but voiceover does not significantly affect learning. Results suggest immediacy with technology doesn't necessarily produce meaningful learning. Good teaching still is the key component of meaningful learning.
