The best teachers were the toughest.
The best teachers were the toughest.
The best teachers were the toughest.
The best teachers were the toughest.
The best teachers were the toughest.
This bears repeating.
When you say, "were the toughest" you mean when you were in school. You weren't refering to your child. So you are sort of mixing your experience and your kids.
There are things like lesson plans, schedules, choice of assignments that aren't apparent to a parent were you talking about them?
What are you arguing about? My last child is graduating in June. I was referring to the experience I've had with all three of my kids.
My oldest is 26 and I'm a veteran at this. The criteria for a good teacher is many things. I was giving an example. But you knew that.
