Is it just me, or does the bad advice format of the article make it hard to see tell the good advice is?
In my early days teaching LaTeX classes, I used to have an example of incorrect input in the first day’s material (forgetting to leave a space after a command). Even though it said before the example that it was incorrect, invariably, at least one person in each class would type it into their computer and have the error returned to them. I removed the example because it only hindered the teaching process. I feel like articles like this which use opposite-speak in making their point do the same thing.
It's a bit more analog, but one piece of advice I got in a teaching seminar was to only ever write true things on the board. This is important because students often zone out at just the wrong time and when they come back and realize they missed a bit of class, they'll glance at the board and furiously start copying down whatever you wrote without knowing the context. If it turns out what you wrote wasn't true, well now a whole bunch of students copied down the wrong thing and are going to be extremely confused why the example they copied verbatim from class isn't working.
