Frantic as had not thought of cool creative exercise before class. Settled for introduction to Eclipse and individual implementation of UML quiz shape system, which class had taken up for last two sessions. Dismayed to find not everyone could code it quickly, but glad that now have some justification for uneasy feeling about student understanding.

Assigned peer review over e-mail. Will glare (nicely) at students if students still unable to complete and explain system by next week, as expect them to review outside class if they feel they’re missing something. Xref: 2003.11.27#6
