If you're tying to discipline children, I think that "punishment" for infractions is LESS MOTIVATING than encouragement when kids are doing something well. This type of consequence is outdated and antiquated, in my opinion.

I grew up doing that everytime I did something "bad". It only frustrated me to sit there and write and write and write. I will never do that to my kids, especially my son, who has dyslexia and slight reading/comprehension problems. It only exacerbates his issues. I do work with him on writing as exercises for his brain but I would never force him to write and write, nor would I do it to my daughter. Not when a simple redirection or time-out is just as effective and way less frustrating.
