      Which of the six principles reviewed above do you find the most difficult to interpret? And why?

      I find most of them familiar and straightforward, but I agree with @tinkerbell and @akiko that the modality principle and the redundancy principle are the two that throw up a few questions for us as teachers.  I think there are teaching instances where reading text silently without hearing any verbal information may be beneficial – I think it depends on the information and task. For example, as a language teacher, we may show an example of written English on a slide and ask students to spot errors. I am not sure talking as they look for errors is helpful. However, I suspect they are aimed more at lecturers? I think @amon246’s point about accessibility is very interesting to consider, too!
