You must be a site member to participate in the Variable Thinking Wiki.
Variable Thinking is a public website and anyone can view what is here. But I don't want just anyone contributing — that is for my students only. So before you can participate, you have to become a Wikidot member — then you can use our "secret password" to contribute.
Follow the instructions below. Joining is a one-time deal. Please do not use your real name when you sign up.
