I think I finally managed to convince a large portion of my students to turn in an assignment.
First, I printed out a summary of their assignments to date and grade breakdown and gave them each a copy. After they had looked it over, I drew their attention to the total grade percentage at the bottom.
"Look at that number. Now, add six to it. This assignment," I said, "that we will be doing for the rest of class will raise your grade approximately six percentage points. It's not hard; it just requires a little thought and reflection. I know you can all do it.
"Remember. Six. That will raise a whole bunch of you up a grade. It's so easy."
You know what happened then? They all worked on the assignment! It was awesome.
I got these Tevas for a trip to Costa Rica that I took with my mom a few years back. I'm still not exactly sure why I got tan ones. They look like something my mom would wear. Still, they're quite comfortable and I have gotten a decent amount of wear out of them.
