I was saddened to read of Seymour Papert's accident.
In my previous life, I was fortunate enough to be able to introduce Papert's Logo to many of my pupils. The effect it had on their mathematical and logical thinking was astounding. I first used it on the BBC computer (remember them?) and then on the RM Nimbus with the marvelous turtle.
It was such a shame that we only had one computer between thirty children, all they could do was encounter the programme, if only they could have spent more time exploring the world through Logo.
I know that children would gain far more from spending time creating mathematical figures in the Logo environment than they do from being forced to watch PowerPoint presentations of mathematical shapes on interactive white boards.
More information about Papert can be found here.
Who would have believed all those year ago that the turtle would have evolved into Lego's Mindstorms.
Intelligent Design indeed.
