Hello Bruce,
Thank you for sharing your post. I also believe that the redundancy principle should take precedence when handling extraneous load. The reader will understand the knowledge better if the content is clear and simple to grasp. For instance, some instructors enjoy sharing lecture slides that are packed with images. After I have learned the Cognitive Load theory, I would advise them to post a different version in Brightspace than the one they demonstrated in class. In addition, I think the signalling principle is crucial. The learning effectiveness would be dramatically improved by significant segmentation.
