The process of grading endless stacks of student papers by putting a check mark in the gradebook and chucking the papers into a box to be returned to students (or recycled). Check and chuck involves no realistic evaluation of student work, nor is it remotely related to teaching or educating.
Let's see, I have 185 students, and I assign 2 or 3 pieces of work every day. I get 2,000 papers a week. I look at a few, but most of them are check and chuck.
