Treat people as if they were what they ought to be, and you help them to become
what they are capable of becoming.
So, here we go, the first instalment of a Teacher Commentary.
If, you may ask, this is the first one, why then is it called “Teacher Commentary 3”?
Fair question, but there is method in this madness. I have decided to number them not sequentially, but in sync with the main Joy of Code episodes. Each Teacher Commentary will get the number of the episode it refers to. Since this commentary talks about episode 3, it is Teacher Commentary 3 (or TC-3, as I will soon start to call them in the headings).
Sometimes the teacher commentaries may not be tightly associated with an episode, but they will still fit in somewhere in the sequence, so they will get whatever number we’re up to in the main episode sequence.
One more rhetorical question before we get to the video: What is a “teacher commentary”?
The TC videos are meant for people who are not only concerned with learning object-oriented programming, or Greenfoot, or Java, but with teaching it. It talks to you as a teacher.
If you are not a teacher, you’re of course welcome to look at it as well, but I’m not sure how interesting this will be for you. Maybe your time is better spent moving on to the next main episode. (You won’t miss anything important.) Your choice.
