If i had the opportunity to teach a class of teachers for one day I would teach them to teach at a steady pace and to not move onto their next thought until everybody has understood the content. I would also teach them to not give that much homework, projects, tests, etc. I would do this because it gives us a little homework to refresh our memory and we wont be overwhelmed with work. It would also save a lot of stress and time for our activities out of school. Lastly i would teach them how to teach in a fun way and not difficult.
