I had a student ask me that today.
Apparently a teacher told her class that we are held accountable for our failure rate. While it is true, I don't see why giving the students the idea that if they fail we will lose our jobs is a good thing.
Some students are willing to fail if they think it would cost you, not realizing what it costs them.
When I was a student, I was responsible for my education and I thrived.
I cannot see how it will work for me to be responsible for what my students learnwhen I have so little control over it.
