I asked a student to draw a tree diagram for flipping a coin three times. We have taught this in more than 3 90 minute classes. It is necessary to master for material that is coming.
What I got had no relation to a reasonable answer.
I corrected him, several times, trying to get him to create a correct drawing. But he refused to change what he was doing. He refused to reference any notes. He just kept drawing the same thing.
What I got was "I tried" - like that matters when you are unable to correct your erroneous attempts. So I drew the tree diagram. And he quit doing any work for the rest of the period.
I could not get him to see that 1) he needed to write it down 2) he needed to learn it and 3) there is no participation credit in his grade.
When did it become acceptable to not even try to learn? Throw some crap on the board, dance for your friends, sit down and talk. This is not learning.
