Figure in Regression

My thanks to Jodeen for the following tip:

I have found that when people (not just students) are learning new skills, they will master one level, but when required to add a new skill, they usually slip a bit on the mastered skill while adding the new skill. Expect this and bare with it. In time people master multiple skills simultaneously. I also let students know that I am not surprised when one thing slips as they learn a new thing, and that I have come to think of it as normal. I also "figure in regression" while I am grading. I think this helps students trust me to be fair with them while they learn difficult things.
