When I taught a class where I assigned essays I confirmed my own suspicions from when I was assigned essays: the majority of the sentences committed to paper are awful drudgery. I then flipped the requirements on their head and removed minimum page requirements and instead had extremely strict maximum page requirements (with of course the objective material requirements of the essay itself). So much improvement for everyone involved. I had to read through so much less pointless material and the students were forced to focus their ideas in a succinct way to be able to get to all of the objectives of the essay in the limited space. Everyone saved time and did better.
