Student Feedback on Individual Homework Assignments
Open-ended feedback on the homework assignments was voluntary and solicited anywhere from 133-229 individual responses representing 37-64% of the enrolled students (Table 4 ). All videos received more positive than negative comments (Fig 1a ). In general, the proportion of negative comments was higher for lecture-style videos (such as those from iBiology and Bozeman Science) than for documentary-style videos (such as those from HHMI BioInteractive) (Fig 1a ). The number of comments varied widely between videos and generally declined throughout the quarter (Fig 1b).
