The summer camp where I had taught Python had a middle school session for students in grades 6-8, which is about that age group. There was a strong correlation between students who did well with Python and students who demonstrated readiness for Algebra I. At the time that I did this, PyKarel worked but GVR (which are both simulations of Karel the Robot, which was originally a paper-based concrete "programming" activity) was not quite ready for Windows (or at least I couldn't get it to run on Windows), so I had to take the activities and modify them to fit the syntax of the environment (which was somewhere between the original syntax and GVR). This was worthwhile though--first I introduced each concept in this environment, in which the students were able to see exactly what was happening, and then when I taught the corresponding skill in Python a few days later I was able to say, "Remember when you had the Robot take out the trash? We used something called a 'while' loop for that. This is the same while, except that we have to get inside the computer's head to know what's going on instead of being able to see what the robot is doing." I also did graphics with them relatively early...I think I have that lesson somewhere around here, but it seems to be on my other computer...which isn't listening to me right now. It might be cranky about the power outage from the thunderstorms last night. The essence of the activity was that I had them sketch their face on graph paper, identify the coordinates of the rectangle bounding each rectangle or oval (or the coordinates of the endpoint of each line segment and/or vertices of each polygon) on the paper, and then use Tkinter to draw their self portrait. The first round of this they used "monolithic" style programs (BUT WITH SUBSTANTIVE COMMENTS, e.g., "#now I'm drawing the mouth", and then these were pretty easily converted to functional versions. Once they used functions, we could take this person's head() and fairly easily put that person's hair() on it, sometimes with amusing results. Between Karel and being able to use graphics early, even some of the students who initially were bummed that their parents sent them to math camp (which I myself wish that I had known about when I was in school) found some motivation to dig deep...not necessarily to do what I "wanted" them to do in terms of the lesson for that day, but hey, if they're programming I'm happy (at least in that low-stakes but mostly high-motivation environment). It's always nice to get feedback, and especially pretty feedback. These activities can act as a "hook." -Lloyd On 6/7/05, dave@lakegregoryics.com <dave@lakegregoryics.com> wrote:
Has anyone here had experience teaching Python to Elementary School children 9 to 12 years of age? This kids are part of a gifted students elective program (upwards of 120 students) in the area where I live. I am in the planning stages of a 3 part series (18 weeks) covering beginning Python and would appreciate hearing about any experience and/or advice you might have.
Thanks,
