More resistors and an uncaring student.

More resistors. Passed out 10 resistors to each student, they taped 6 of them with leads exposed to a sheet of paper. They decode the value, later they will use a DMM to compare a measured value.
There is one student who seems not to be interested in anything. I was attempting to help him but he pretty much ignored me. He would turn around and pester the kid behind him, he would ask totally unrelated off topic questions. It is not clear to me whether he is worth my time. There are many other students wanting help who are also interested. I would very much like to break through his defenses. The teacher says that he is known to be ADD and may also afraid to try, if he tries and fails then he has no excuse. If he does not try then failing is his choice, IE he is in control.

Once I was a lab TA and the students had to use a Wheatstone bridge and known resistors to measure an unknown resistor. They did not realize that I had preselected resistors that did not match their color codes. I.e., they had all been run over their power rating at some time and suffered a permanent resistance change. I measured and wrote down what the actual resistances were.
It was interesting to see who used their actual lab data to get the actual resistance, vs. who fudged their data in order to make the answer agree with the resistor color code.Posted Sep26-09 at 09:59 PM by Redbelly98

i had a brilliant teacher for only one lesson.(i was in the wrong class)
his introduction was "i don't want to insult your intelligences but see if you can help me solve this problem"
he in effect found a challenge that related to the class
he sort of got alongside th eclass and as we progressed through the problem he threw in clues -- a bit like a detective thriller-
today i can still remember every thing he taught me
