So when I homeschooled my daughter and edited her papers, that was afterschooling? Huh? And when my college student has someone edit a paper before turning it in, that is afterschooling? And when my best friend who attended private school came to me, a public school student, for help with her papers, I was afterschooling her?
I have never seen the term applied to college students.
As for you being a child and helping another institutionalized child ( in this case privately institutionalized), yes, you were “afterschooling”. I see this among the Latino children in our congregation. They find someone who is a good student, usually someone who has been afterschooled. Make friends with them and then ask for help.
Guess who is taking all the credit for the improvement in the children's scores? Yep! The local government school!
I used to tutor but finally had to stop. The methods used by the school were so irrational that I was afraid that I would make snarky remarks about the school and the teachers. I didn't see how that could be helpful.
