Years ago, when I was in high school, I had a casual attitude toward studies. I liked my free time and didn't have to work hard to do fine. My first biology test in the tenth grade I had my usual laissez faire attitude. The teacher handed back our tests and announced the results in order. I had a 78. He called that grade out after giving the A and B results to other students. I was humiliated. After that, I never got less than a 100 on a test. Every week, mine was the first name called.

What a smart teacher. He knocked a lazy student off her stride and got the very most out of her. Leave it to a biology teacher to understand social motivation.
