Quote:It's not that difficult really. Consider this simple example. Let's say a math teacher has 20 students and their only goal is to teach multiplication. Let's say after a couple of months half of the students can't tell you what 5 x 5 is or 12 x 3. That would possibly indicate a bad teacher.


Of course, this is a very simple example that would have other factors involved. For example, what if half of the 10 students that are failing failed to complete homework assignments? That would be an indicator that the students and/or parents might be a problem.

So it's actually not really easy? Because the example you gave is extremely basic, it's a very hard thing to get right.


It's not as easy as "oh you failed this test, that's the teachers fault." And "you didn't do homework, that's the students fault."


It's an extremely complex situation and is a reason why no one is doing it right now.
