“…Online courses, which are not constrained to brick and mortar classrooms, allow students to be anywhere while interacting electronically with the course material, other students, and instructors. Instructors of online courses are concerned with the method of course content delivery, which could include the use of animation (e.g., Dunsworth & Atkinson, 2007), audio narration (e.g., Johnson & Rubin, 2011), elaborative interrogation (e.g., Dornisch & Sperling, 2006), video (e.g., Merkt & Schwan, 2014), or just prepared PowerPoint slides (e.g., Stone, 2017). Except during proctored testing, instructors do not have control over the environment in which students are experiencing what might be considered the classroom experience.…”
