When my daughter Laura was in third grade, she believed that her teacher, Mrs. Billerbeck, was the Source of All Wisdom and Knowledge. If Mrs. Billerbeck had not said it, it was not — could not be — so.
Conversely, my straight-A college grade-point average (which I like to think was higher than Mrs. Billerbeck's) was totally discounted. I was totally "iggernut" (my daughter's word for ignorant). I knew absolutely nothing and was ineducable.
With the passing of years, Mrs. Billerbeck's influence has lessened. My daughter, who now has a grown daughter of her own who thinks she is "iggernut," phoned to tell me, "It's amazing how much smarter you are now than when I was in third grade."
Amazing, indeed. I've forgotten more in the intervening years than I ever learned.
But now that I am no longer "iggernut" I'd like to say a few words about mind sets being a detriment to learning.
