For example, do they ever need papers graded, errands run, whiteboards cleaned, someone to call absent students, a substitute instructor, a ride to class, a babysitter?

You might think that is silly and that you couldn't be a substitute, but all you would have to do is show up and put in an ASL video and/or collect whatever papers are due that day. If you become a "teacher's aide" you can sit in class free. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
