It’s the end of a midterm/semester: One student gets an A and another student gets an F.
People are quick to judge that the F student probably deserved it.. didn’t pay attention in class like the A student.
But if the A student had already known the subject before starting the class, then potentially the teacher is at blame, as neither student learned anything new.
If we were to test students before sending them to a class, and only send people that don’t know the subject, then everyone in the class would be on a more equal playing field..
This approach seems pretty obvious to me.. Why don’t people do it?
Lots of schools already have a tiered system of class levels.. But to be placed into one requires the recommendation of a previous teacher.
Why don’t all students just get tested before starting a new class?
