The pure and simple truth is rarely pure and never simple. — Oscar Wilde
Today a long, and quite full episode. We encounter various very important concepts for the first time: local variables, class types and object interaction.
If you have questions left after watching this – don’t worry. We will look at all of this again in more detail in future episodes. And you can use the comments below to ask your questions (or make any other comments).
By the way, I just noticed I made a mistake. (Yes, that does happen!) There is a bug in the program that I’m writing in this episode. Can you spot it?
You must be the change you wish to see in the world. — Mahatma Gandhi
After a few days’ pause, here’s another video. And it’s time for a teacher commentary again.
We’ve crammed in quite a bit of material over the last few episodes, and the question now is: Firstly, how do we keep motivation up? But more importantly, do the students actually understand what’s going on?
One interesting suggestion I received from a viewer out there about the Joy of Code video series is to make the videos downloadable, because YouTube is blocked in a number of schools.
That seems like an obviously good idea, so I’ve done that now. Under every Joy of Code video, you will now see a download link. (On some (most?) systems, just clicking the link plays the video in the browser, so right-click, and choose “Save Link As…” or the equivalent option in your browser.)
Another advantage of this is that you can play the video in its original resolution (without up- or down-scaling), which should give you good high-def clear text on screen.
