Brings up a corollary issue regarding learning theory.
I recently picked up another PE, but when I learn the material, I learn it best still by handwriting the formulas and notes.
My organizational reading skills are much more rapid using a PC and the Find function, but learning associations are still better defined by handwriting.
I wonder how the younger generation is learning.
Actually, that is known. When you make the muscles of your arm and fingers push that pencil across the paper, new chemical pathways are created in your brain, which are different from just reading the material. It does make the material clearer and firmer in your brain. So, a good teacher uses a combination of methods, including physical writing, to help the students learn.
