Hi Flamma,
I agree that the redundancy principle is very important and I also think that it needs to be considered as one of the necessary features when designers of contents are creating learning pieces. I think being concise and clear in the content would greatly help the learners focus on the key points presented.
On the other hand, learning contents would sometimes include a lot of key points and redundancy sometimes seem unavoidable. What would you do to this situation when you are building a website if you need to present many points? Thank you.
