She also spent some time at Xerox PARC where we duplicated her interfaces and did many similar experiments with chldren 3 years on up. Might be worth exploring what's already been done here to get ideas and takeoff points.

We can demonstrate many topics in Turtle Art, even if the children can't yet program such demos unaided." Edward, to progress discussion, I have done a mock up graphic at <a target="_blank" href="http://wiki.sugarlabs.org/go/User:Tonyforster">http://wiki.sugarlabs.org/go/User:Tonyforster</a> I have only done some blocks. I have concentrated on turtle motion, pen and flow control. I think the mathematics blocks are best left as is. Others, eg push and pop heap may be too difficult for pre-literate children to bother with. Likewise the portfolio and red box tabs. (Maybe keyboard input is important enough to bother with but the 2 step process it uses, one block to read kyb and another for its value, is conceptually difficult. First the interface should be simplified.) Questions the exercise has raised for me: To what extent could pre-literate children use Turtle Art? Are graphics on blocks really better than text? Does keeping text labels help develop literacy? What graphics are best? Should the more difficult blocks be omitted or kept with text labels? Should they be on different tabs if retained? Where can we do user testing and get feedback?
