A Crossover Randomized Controlled Trial to Evaluate the Use of Animations and Interactivity in Anatomy and Physiology Education

Abstract

An increasing number of studies suggest that there is no difference between live didactic lectures and video podcasts of the lecture content in student learning. However, several studies have recently shown that instructional videos that include interactivity and animations increase retention and transfer of content in biology and engineering. The purpose of our study was to evaluate the effectiveness of interactive videos that included animations on anatomy and physiology education.A crossover randomized controlled trial was designed and completed in the 2016–17 academic year using undergraduate students (n≈150), comparing live lectures to interactive animation‐based videos in an introductory anatomy and physiology course. The study included undergraduate students in several undergraduate programs, including Health Sciences, Nursing, Midwifery, and Engineering. Multiple‐choice question (MCQ) pre‐intervention tests were designed to evaluate prior knowledge among participants who were randomized to either the lecture or video intervention. MCQ post‐intervention test performance in each group was compared to the pre‐intervention baseline, immediately post‐intervention and after one week. Live lectures were assigned to the same instructor as the narrator of the videos, in addition to featuring the same educational graphics. The videos were created according to guidelines described in the literature for the integration of interactive animations while minimizing cognitive load.Both groups were evaluated on the outcome measures of retention learning and transfer learning, as assessed by MCQs. Statistical significance of inter‐group differences were determined by ANOVA. Students were also asked to complete a questionnaire designed to collect qualitative data to assess engagement in multimedia education as well as demographic characteristics. This enabled an analysis of other variables including interest in the subject, course performance, and program of study. This study provides evidence regarding the use of interactive videos in anatomy and physiology education.Support or Funding InformationThis study was funded by the Paul R.
