The multimedia equivalent of "chalk talk" lectures from face-to-face courses, where the instructor writes or draws on the whiteboard to illustrate course concepts to students. Instructors can replicate this in the online space through whiteboarding applications such as Explain Everything that draw out and explain visual concepts using diagrams, graphs, or equations. The Denney Digital Union provides a user-friendly video studio where instructors can record a "lightboard" lecture. These lectures feature instructors standing behind a plate of transparent glass and delivering their "chalk talk" to the camera. Lightboard lectures can help instructors amplify their presence within the course, as students can see their instructor in the video.
