It depends. If there are 29 other students in the class that got it just fine and the one is struggling, then I would think that the teacher would have to make a judgment about how much time to spend on that one student. Or maybe that one student needs to be in a different class with more one-on-one for a particular subject. What a valid statement, you're missing my point. In the scenario I listed above, the teacher is already re-explaining the lesson again, to that specific student. So if you read my statements in that context, the difference is -- when already repeating the lesson individually, does the teacher say precisely the same thing, word for word, or does the teacher try to explain it in a new way?
