When I was a less experienced teacher, I made a big mistake. Students were composing essays in a computer lab, and one young man thought he would be clever. Instead of writing, he spent his time shopping for an online essay. A flash of his parents’ gold card near the end of the class is what alerted me. He let his trick be known to the students around him and a bustle of barely repressed giggles and furtive looks ensued. When he came to the front of the class to hand it in, I handed it back and then pointed to the door. I said, loudly and firmly, “This is unacceptable and I’d like you to get out of my sight.” The class went silent and I was momentarily thrilled that I’d spoken so bluntly. However, I changed my mind when that silence persisted until the end of term. Without meaning to, I’d intimidated every other student in the room, none of whom, as far as I could tell, was cheating. I’d made classroom discussions difficult, and I had no one else to blame. Click here to continue reading at Quillette.
