I am planning a multi-year grade school sequence to introduce CS ideas using TA, with a transition from TA to Python by way of Python blocks in TA. I will take a look at your work, and see whether it makes sense to treat it as a followup to mine, or rather to design mine to lead into yours. Among the topics I intend to emphasize are Church's Thesis, Gödel recursive functions, parse trees, stack programming (and hence RPN), language interpretation, and building a Turing Machine in pure TA. > Thanks! > > jeff elkner > open book project > http://openbookproject.net > > On Wed, Jun 1, 2011 at 6:37 PM, Edward Cherlin <echer...@gmail.com> wrote: >> On Tue, May 31, 2011 at 16:59, Jeff Elkner <j...@elkner.net> wrote: >>> Hi All, >>> >>> I'm working on an introductory CS book using Python with the turtle >>> module, >> >> Under what license? >> >> Can we talk about using Turtle Art in Sugar as a starting point? it >> can call Python functions assigned to blocks, providing an easy >> transition from pure TA to pure Python.
