Enigmaticicity, perhaps?

When examiners are writing assessment instruments (i.e. exam papers of one sort or another), they are asked to consider two constructs (which can be measured statistically, and by triangulation with other assessment methods): 1) validity: does it test what it's supposed to test? 2) reliability: will it do that the same way with any member of the given population? Being picky, that's only one of many types of validity, and only one definition of reliability. I'll concede that both definitions given are those most likely to be cited by the person on the street though.

Dr M, Nice to see your posting! Yup, I know - I was doing the simplified version (I didn't want to get unnecessarily complicated, and the definitions, I think, served for the example ...)

Enigmaticicity, perhaps? Tone (Enigmatist) Ah, but Charlie - or may I call you Charlotte? - to be a true enigma is to have no knowledge of one's own enigmaticism.

Amanada, >Ah, but Charlie - or may I call you Charlotte?<Um, why? Are you getting confused? Someone that I, on occasion, have mentioned hereon (or rather have done so otheron), and who is very dear to me, uses the pen-name "Charles Sexton". (And their sex has not been divulged.) But anyways, I don't think that it is considered legitimate to apply diminutives to pen-names (discuss?). After all, one might (just) call Winston Churchill as a writer "Winnie", 'cos it's a diminutive of his own real name, but surely one would not call Mr. Clemens "Markie" when he was using his (well known) pen-name?

I find that including misconceptions in multiple choice response options can raise awareness of difficulties students may not otherwise have recognised. I now see fewer of these misconceptions appearing in their final coursework. Our (university) students do seem interested in exploring their misconceptions, when these are pointed out to them.

Good point, SusanB.
I used to use hand-held voting pads (like on "Who Wants to be a Millionaire") once or twice a day on my courses -- the results weren't recorded (and were anonymous anyway), but were projected as a graph for everyone to see. Great fun, and very useful as a quick check that I'd got the key points across to everyone.
Voting has to be multiple-choice, and it was always so much easier to write say four possible answers (of which three are plausible but wrong) after I'd given the session a few times. Until you actually lecture it to real people, you don't realise what they will misunderstand!
You know the sort of thing:
"A standard KiloStream line runs at
a) - 64 kilobits per second b) - 64 kilobytes per second c) - 640 kilobits per second d) - 640 kilobytes per second"
Project that on a screen and let everyone press their buttons. The results are shown as a bar chart -- number of people voting a, number voting b, and so on.
Very, very revealing for a trainer. We're not nearly so good at explaining to everyone as we think.
I could never decide if it was helpful to include (e) Don't know.

I agree that SusanB has a valid point there.
More people should employ your checking method, Paul. I usually ask my students straight out, but I have only one or two handfuls at a time, and by now I know pretty well what their misconceptions are likely to be. After a while I usually know the students well enough to guess who thinks what.
I'm still caught out by the occasional divergent thinker, though. This is one of the things that makes teaching fun, of course!

Students can also get quite motivated to explore different viewpoints or possibilities, once they realise that not everyone believes the same. It seems to be a useful way of sparking discussion. Susan.
