The greatest mistake I ever made in my education was failing a physics course at Cornell.
I opted to take an auto-tutorial class that did not require calculus because I was afraid to make math errors. Up until this point, I had never failed at anything. It was a turning point for me. I had to dispel prior notions of learning to succeed. I accepted that there would be many errors along the way. I relearned the basics I had previously memorized through difficult examples and repeated detailed lab work.
On a broader scale, changing the way we see errors–as natural by-products of the learning process rather than time-costing falters to be avoided–can help us produce better learning outcomes in education.
