thanks for the hints, Edward and if you may give me more details about the projects you pointed, i'll check if they can be coupled with mine in the future; i am deeply interested in getting python and CS way of thinking into high school math learning and everything related is well accepted i am a HS math teacher and i like to experiment a lot with those young guys who can stand the trial teaching -- roberto OS: GNU/Linux, Debian _______________________________________________ Edu-sig mailing list [email protected] http://mail.python.org/mailman/listinfo/edu-sig
