So I had the usual PowerPoint presentation, with a lot of facts about Williams plus a couple of pictures of children with the disorder, and then I also gave a lot of examples, like a 15-year-old WS patient's description of an elephant, a WS child's lexicon of animals compared to that of a Down's Syndrome child, and (the one that made everyone laugh) a WS boy who didn't utter a single word until he was three, then burst out with a frustrated, "Jesus Christ, this doesn't work!" (in reference to a fan).
Then I played the phone conversation that Dad taped with Laura and, while it played, scrolled through a Word transcript that I'd typed up, so people would be able to understand it more easily. Then I showed a slide with a sample of her handwriting (a letter she sent us), showing the contrast between her command of speech (which the teacher described as, "Really, this could be a conversation between me and my 'normal' mother!") and the (typical) poor fine motor control of WS patients. Everyone was really interested in her spelling, such as her writing 'when' for 'went', but Sergey (the teacher) thought - as I did - that was perfectly logical, "because that's what she knows, the phonology." And everybody stayed 'mentally awake' the whole time, as far as I could tell, which was great, since we've definitely had a couple of 'put-you-to-sleep' presentations (*cough*Bart*cough*).
Anyway, after class, Sergey had no criticism whatsoever - he called it "extremely good" and "really excellent" and said I'd done everything he could have thought of for me to do. According to him, it would have been an A based on the content, but since I "showed so much personal creativity" and went above and beyond what was required, I got an A+. (That distinction is negligible in the States, but it's significant here.) He even asked for me to put the .mp3 file and transcript on Workspace (the website UCU uses for assignment hand-in and such) so that he could use them in the future. And when I asked him, he also said that he obviously wasn't trained to make a diagnosis, but based on what he saw, he felt she did indeed have Williams. So getting that 'second opinion' was nice, too.
So, bottom line: Woohoo!!! :)
