The winter quarter started a week ago, and it’s going to be a challenging one. I’m teaching a half class overload that happens to be a brand-new class, which I expect will leave me struggling each week to stay on top of my work. As you might imagine, I wasn’t looking forward to this quarter. And then last week I walked into the first session of the new class and made a happy discovery: a majority of the students in the class are either ones I had in the introductory Python course last quarter, or are also enrolled in my second quarter Python class this quarter, or both. I had forgotten how much better it makes teaching to have the class full of people you know. I don’t get that experience very often anymore, and I plan to savor it.
