People learn better from animation and narration than from animation, narration and on screen text.
Animations are great for learning. Here's an example (yes a transistor again) that the learner can play with - its interactive.

According to principle 5 it would be improved if the instructions were spoken.
Is that possible with an interactive animation such as this?
What would happen as you advance the slider and the instructions change?
Is it helpful to have a written explanation to look at as you try different parts of the animation?
Just how would you apply principle 5 to this example?

We had the narration also running as on screen text. Breaks the Redundancy Principle but assists otherwise baffled overseas students for whom English is not their native language.
