These post-lecture summaries are pretty neat. Not only are they an uplifting “hey, you did this” message, but they are a useful recap and give you a moment to think about some of the specific lessons now that you’ve had experience working with them. They are also an opportunity to say “hey, this specific little thing” may have been specific and little, but now you’ve learned in general how to do this and when it could be useful.
I like them.
