I believe it was 4th or 5th grade, and one think about myself back then, I was really, really, really messy. It was beyond anything that you could possibly imagine, one of those with papers hanging out from one of those hinged desks and the occasional smell of something down in the bottom that either I forgot about or just didn't care about. Looking back, it was disgusting, and I think that my teacher started to be annoyed by it.
She proceeded to make me sit out from recess everyday until my desk was in order, it took about 3 days for me to actually fight through my youthful revolt and do it, and then about a week later I needed to sit in again, and then probably once a week for the entire semester. Sure, I hated it. I resented my teacher for making me do all this work and keep me away from my friends. Back then I thought it was crazy. However, what it did do is got me to keep my desk clean, and I applied that to the rest of my life, to cleaning my room, to keeping papers and notes organized. It really did change the way that I was, and caused changed that I'm still huge into organization and being cleanly.
Even though a teacher has to discipline their students, just like my elementary teacher had to do, it it is something that is done for a reason and I think as future teachers we need to realize that how he treat our students is important for now they eventually develop into adults. Discipline isn't such a horrible thing, it can have lasting impressions on students if used the right way.
