How might I structure an assignment with two "levels"?
Ooh, I have experience with this one!
I tried once giving a huge lab with lower scores for progressively simplified versions (to allow for students with lower abilities to still complete the lab), an …

Counter-Example for Computability
I guess I'm not understanding what the problem is with fuzzy when talking about computability with a group of 12 year olds. They can instantly grok the notion that the question isn't one that compute …

Presenting Mapping Reducibility (for P vs NP)
So, I am preparing to teach about P and NP for the first time. I know that I need to teach about Mapping Reducibility (aka One-to-One Reducibility). Can anyone recommend a set of algorithms that are …

Computers are down; what's in your bag of tricks for teaching CS when they can't get on a co...
It depends so much on what we're covering. In principle, anything which gets them doing or moving also gets them learning. Here are a few more ideas:

How to stress the importance of testing code?
The first problem my students always have with this is that they don't even understand how to test their code. They've run the program, and it works. So... it must work.
I have two approaches to thi …

What are good examples that actually motivate the study of recursion?
One good example is to make permutations of all of the letters in a word of arbitrary length. It's quite tricky to do iteratively, since you essentially have to recreate the program stack to get it d …
