I've been a scribbler for many years.
My journals are full of doodles, drawings, chicken scratch.
Now I know why -- it helps me learn.
Ainsworth et al, in a paper called "Drawing to Learn Science" describe what happens when you draw.
Check out their Youtube video too.
Wish I'd learned science this way...
Makes me think of Darwin, Leeuwenhoek and other greats.
Drawing things out in their notebooks, the messiness of the pages mirroring the messiness of learning & discovery...
So...get drawing ya'll!
