Has learning through doing repetitive exercises and mechanical non-creative exercises been researched and analysed sufficiently for College and University level courses? Have there been surveys and polls for High school and University Level students about whether they appreciate these repetitive and uninspiring exercises for learning and if it helps them? Have any College level students indicated Repetitive and uninspiring often mechanical learning is tedious or monotonous and doesn't really explain that much?
Has it been studied? I don't know.
Does it work?
In my opinion, no. I have taught kids that came from asia where their math was done by rote. Their arithmetic skills were impressive, but when presented with a large number of new ideas they had trouble seeing how the pieces fit together, and were often at loose ends when faced with a new variation.
Is there a place for rote learning? Yes. Doing many problems. This helps build facility with algorithms.
