Reform K12 has a nice post about a teacher who got a thank you from a parent.
See, I’d given her daughter an F for the third quarter, and her mother couldn’t be more tickled.
What this failing grade had done was give her daughter a well-needed kick in the pants. She’d done a mediocre performance the first two quarters, but this failing third quarter grade gave her the sobering thought that she might fail the entire course.
The student started to show up every day and do the work.
