well, the semester is drawing to a close quickly, and i am glad for it. i created about 30 brand new lectures. kind of proud of it, at least some of it. the real meat was in the classroom sessions – both classes were good, one was small (usually 6-7 students) and grew into ‘outstanding’. the last step: exams, new to me as a testing method (including my own studies – in physics, we solved plenty of written exercises, but never had to endure a multi-hour exam). i would much prefer a mixture of essay and group presentation.
