(Speaking as a high school teacher with ~120 students in 3 different levels of computer science courses in a public school in Seattle)
I guess my point is that computer science in general and programming specifically have so much opportunity to be exciting for both the majority of students who are burned out on "traditional classes" as well as the minority of students who "know they likely won't be taken seriously if they boast of math skills and yet evidence no ability to think like computer scientists" (come on, that requires a high level of intellectual sophistication and is REALLY rare). I think we need to exploit that opportunity to its full potential. I steer away from purely math-oriented examples because they alienate the majority of my students. It's a tricky balancing act and I certainly can't claim to have figured it out. Selfishly, I'd like to see the brilliant minds in this group sharing examples or ideas that the average 13-18 year old would find exciting and worthy of further exploration. For example, a while back, Gregor Lingl shared a Turtle Graphics example in which a turtle performs a random walk collecting "coins" as it goes. There are lots of interesting mathematical concepts to discuss in there and it requires students to use a lot of programming tools and ideas but it also has a "cool" factor. Furthermore, the basic idea is reasonably simple to understand and to see a use for (we can simulate other kinds of real-world situations, etc). I agree that we as educators are not entertainers and that learning is important for the sake of learning but at the same time, we need to be careful not to on one hand deplore the fact that students aren't taking computing courses while on the other creating courses which are dry and esoteric. Again, I don't claim to have figured it out. I say all this but at the same time, I'm wary of courses which expose students to computing applications without giving them many skills (programming/critical thinking/math/algorithmics) or which rely entirely on one application space (animation, games, personal robots, whatever) to be "sexy" and capture students' attention. I suppose it's all about goals. One potential goal for using Python in teaching is to reinforce and develop mathematical reasoning skills and it seems like that's the focus of a lot of the people on this list. I believe that's a worthy goal and I try to accomplish some of that in my courses as well, but it's not my primary goal. I guess my primary goal is to encourage students to see software as something they can be a part of rather than simply as something they consume or are forced to live with. I don't have a ton of concrete ideas on how to do that -- I think I've somehow crafted successful courses on intuition more than anything else and can't really formally express what I'm doing yet -- but I really do see it as a very different goal that leads to very different types of courses. And maybe I'm the only one who sees the majority of examples and ideas on this list as esoteric! It's something I often find myself thinking so I thought I'd try to describe and explain a bit of my discomfort. Not sure I really expressed myself very well -- sorry! Hélène.
