Sarah et. al.,

Although I come from the tertiary branch of the educational system, 
my first objective for RR would be in the primary and secondary 
schools. And for this reason I support Rev's stated objective of 
implementing Turtle Graphics for Revolution.

By implementing TG  I mean creating another class of controls, turtle 
controls, like buttons, only different. Their properties would 
include position (standard Cartesian coordinates with a user defined 
origin-not the same as screen coordinates), heading (standard 
Cartesian polar angle-0 along the right-pointing x-axis0, pen state 
(pen up or pen down) so that they may draw (leave a trail) as they 
move.

They would have an augmented vocabulary, responding to such commands 
as Forward, Back, Right, Left, setXY, setRA, incXY, and functions 
such as xyCor(of the turtle), direction(of the turtle), distance(to 
any to any point), heading(direction to any object) etc.

And the course content would be directed toward programming as a 
general problem-solving tool, as opposed to a course in computer 
programming, recognizing that programming is a generic tool, useful 
in a wide variety of endeavors.  Examples would include, beside text 
manipulation, applications in the sciences, acknowledging that every 
scientist should have some programming experience, and that this is 
the audience most likely to be attracted toward, and in need of such 
a course.

(Some examples of application of TG to mathematics and the sciences 
can be found in:
