Then we can get some user feedback >Nobody knows the age limit on teaching graphical programming. Experience with Scratch and GameMaker is that it works at the whole of a class down to grade 3 though I have had smart individuals down to grade 1. But I note that the cognitive load is higher for these programming tools, they allow multiple objects and are event driven. The beauty of Turtle Art is its simplicity, only 1 object, the turtle and no need to get your head around events and their associated actions. So I agree, lets get something out there, get it road tested and refined and see how low it will go. > ←→↑↓↗↘↶↷↺↻√∡⊥∧∨∼ and others. Was thinking, turtle motion arrows should have a picture of the turtle too - to underline that they are from the turtle's frame, not the child's. Younger children will have problems with mouse control, particularly with the XO, maybe the blocks should be bigger? In slow mode, the blocks could light up as they execute. Clean could be a pencil eraser or blackboard duster. Which are better for flow control, smileys or coloured dots? 0-= I prefer 012, if they can't recognise numerals they will have trouble entering them anyway. Where the graphic is not reasonably intuitive, maybe better to retain the text? At least an adult could read them. Walter is going to do tool tips, that would make my point irrelevant, graphics on blocks with text tooltips. >They don't need localization. This is important for children whose >language of instruction is not their native language. English in >Ghana, for example, or French until recently in Rwanda. Yes, reminds me of Vanuatu, their local language is spoken the village, Bislama is the national language but the language of instruction may be English or French. I doubt we would ever see localisation down to the local language level, maybe 1000 speakers. Final thought. We are not eliminating language, just substituting one symbol set for another, hopefully more recognisable ones. Language in the wider sense is symbols with meanings which can be used for communication and as tools to think with. Mathematics is a language too. Though some blocks could have photorealistic symbols, we are mostly using abstract symbols like the arrow. (the arrow is based on the bow and arrow but we have all but forgotten the roots of its symbolism). Which gives me another thought. Could we have animated images on the blocks. Then we could photorealistically represent actions like move and flow control. All just topics for discussion, very happy with what you have done, looking forward to the installable bundle. Tony
