In this research of fMRI problem solving from researchers in Indiana, adoption of a verbal / algebraic vs. visual strategy had similar patterns of activation in brain networks, but the visual strategy was less demanding on working memory, and visual strategies were preferred more often from students who had working memory limitations.
Which strategy would you choose?
The month after April is the month before my favorite month. What is my favorite month?
It's also interesting that individuals with more limited working memory tended to have a reduced reading span (mild dyslexia?).
One question that comes to mind is whether most algebra or logic teachers would teach verbally or algebraically rather than visually. And if so, is that why students with more limited working memories or those with a bias toward spatial problem solving may be being left behind?
Studies such as these are very basic, but surprisingly there are still some educational pedagogues who suggest that teachers should not tailor instruction to different types of learners.
