The Redundancy Principle

The Redundancy Principle is similar to the Modality Principle except it states that delivering the same words using both audio narration and screen text at the same time is redundant (Clark & Mayer, 2011). "People learn better from graphics and narration than from graphics, narration and on-screen text." (Faculty Center for Learning Development) 

I think this video regarding a MOOC offered by Coursera does not violate the Redundancy Principle because what the instructor is saying (through audio narration in the video) is not replicated as words on the screen. However, the video is embedded on a page with A LOT of text on the screen that competes for the users attention while the video plays on the page. Although the words are not redundant, I believe the viewer may be overwhelmed with words unless he or she uses the feature to enlarge the video to full screen while watching the video.This example does meet the principle because the words on the screen are not the same words spoken in the video.
