My grandmother was the first person to show me things about life,nature.Simple but important things.This is because I used to spend a lot of time with her.
She was a wise woman even though she had been to school just for a few years.
I think a teacher goes with a pack which has a lot of different things: guide,monitor,psychologist,tutor,social assistant,lecturer,facilitator,''provider of knowledge'',peacemaker or mediator,counsellor and many more.
This is my opinion.As for Oxford,I don' t know yet.I may use some things with my students,but I don' t think it will change anything.
