Screencast Videos
What is it?
A screencast video features a recording of a computer or device screen and audio track. This style of video can be created nearly anywhere with a computer and microphone (or tablet).
Why should I do it?
Instructor Presence
Instructor presence is an educator's ubiquity in a classroom via three modalities: cognitive, social, and teaching. At times, the lack of a physical space can make the online classroom feel devoid of an presence. Using a screencast can help establish your presence in the classroom because your voice can be heard by learners.
Demonstrating
Screencasting can be used as a means to demonstrate. This is valuable for reviewing and clarifying instructions, showing how to use applications, providing a walk-through of steps in a process, or demonstrating how to solve a problem.
Cognitive Load
Cognitive load is the amount of mental effort used in working memory. As students work to learn new information, we can help them manage cognitive load by adhering to the Modality Principle. This principle indicates that people learn better when presentations include animation and audio narration versus on screen text. Learn more about Designing for Learning.
