This study examined teaching assistant’s immediacy in lecture/laboratory and self-contained classes. Two hundred fifty-six students responded to instruments measuring teachers’ immediacy behavior frequency, perceptions of instruction quality, and cognitive learning. No significant difference was identified when comparing lecture/laboratory and self-contained teaching assistants’ immediacy behaviors. But all students who observed frequent immediate behaviors demonstrated higher affective and cognitive learning. Teaching assistants’ ratings had significantly higher levels of faculty-student interaction for self-contained sections but lecture/laboratory sections were significantly higher for student effort/involvement.
This analysis investigates two differential PowerPoint slide designs—presentation and teleprompter—for multimedia learning. Eye tracking measures assessed differences in fixations. Participants demonstrated greater fixation counts for teleprompter slides, measures of aesthetic liking evidenced that slides incorporating imagery resulted in more pleasurable learning experiences, and visually-based slides influenced more reflective learning and greater activation of information processing. The results offer practical advice for instructors wishing to increase the slide design effectiveness for improved multimedia learning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
