Abstract:

This pilot study obtained baseline information on verbal and visual rhetorics to teach microscopy techniques to college biology majors. We presented cell images to students in cell biology and biology writing classes and then asked them to identify textual, verbal, and visual cues that support microscopy learning. Survey responses suggest that these students recognized some of the rhetorical strategies used and conflated others, revealing intriguing questions for further research in undergraduate microscopy education.
