The effect of Snapchat on learner satisfaction and anatomical knowledge retention: Preliminary observations.

Biomedical educators have turned to technologies, like social media, to supplement progressive reductions in time spent in class. Many studies of social media have been limited to quantifying learner satisfaction and studies on the effects on learning outcomes are sparse. The purpose of this study was to examine the effects of using Snapchat on learner satisfaction and learning outcomes. A Snapchat account was used to share blood flow diagrams during the anatomy course of a physical therapist education program. Viewing statistics were recorded, a survey was distributed, and learning outcomes quantified at the end of the course and 12 months later were compared with a control group that did not have access to the account. Eighty-two percent of the class subscribed to the Snapchat account and 86.7% of the subscribers completed viewing of the five drawings posted. Learners rated the account as extremely accurate, were quite interested in more content presented, and felt quite confident in the diagrams. Performance on blood flow questions on the end of course examinations were similar between experimental and control groups. Assessments administered 12 months later revealed greater scores for the Snapchat group (90.7% correct) compared with the control group (86.7% correct,
