What are some good in-classroom techniques for being a more effective K-12 teacher?

José Romão created a document from a thread on Quora, in an effort to generate more thoughts on how one can become a good teacher. We are planning on getting as many ideas as we can, extending the ideas in more detail, and either creating a short "this is how you can become a better teacher" book or presentation.

Add some of your ideas here on how you think people can be more effective classroom teachers.

Password Strength

I’m using the following xkcd comic to help the teachers at my school with their password selection.

Password strength


There is also a very useful script, created by Steve Gibson, available to test how long it would take a brute force attack to figure out your password with a computer. While I don’t recommend entering any actual passwords you intend to use into an password strength checker (there aren’t that many websites out there, so an hacker could easily steal the passwords you enter into their "password" checker and try them all over the place, thanks to @drdouggreen for the reminder), this can be an excellent way to experiment with different types of passwords.

I also recommend reading this post I wrote about how to change your password for every service you use, without having to memorize a new password for each of them.

As suggested above, we’ve spent many years training people to use complicated passwords which are actually not all that secure, when instead, you can use a longer, much easier to remember, password that is much more secure.
