I considered it in terms of teaching computer science, especially given (http://carlos.bueno.org/2011/09/ipsum.html http://carlos.bueno.org/2011/09/ipsum.html) and (http://carlos.bueno.org/2010/07/corrupting-the-youth.html http://carlos.bueno.org/2010/07/corrupting-the-youth.html). In that frame of mind, chapter 0 exert seemed like it mentioned computer science concepts, but they weren't really explored as such. I interpreted your goal as edutainment, a noble goal, but one that fails so often it triggers a certain amount of skepticism. Being entertaining is a tough challenge as it is. Trying to be entertaining _and_ informative, and you're unlikely to accomplish both. That was my biggest challenge as an EFL teacher - I spent most of my time planning activities trying to be engaging and informative. Even then, I'd say only ~30% of the time did I really get the balance right in my lessons and that's in an active media where I can react to the class. If its just meant to be a bit of fun with a topic then its a different thing. Perhaps its better described as a pop sci book for children. Like how Brief History of Time didn't go into detailed maths, but gave the reader a working mental model of complex phenomena in an interesting way. Perhaps Lorem Ipsum aims to give children that mental model of computation, without any expectation that they could reasonably apply it. Is that the sort of thing you're aiming at? Edit: I just read through (http://carlos.bueno.org/2011/01/tortoise.html http://carlos.bueno.org/2011/01/tortoise.html) extract you mentioned, and am a lot happier with it. You do have a really good way of personalising problems so that its about people all the time. I really like that, because that's something that is extremely important with children (and some adult learners). I remember I first groked multi-dimensional arrays from this MS-BASIC book I found in the school library, where it was explained by a large red jellybean jumping on this grid. I never understood the C-language book that dad gave me. That jumping jellybean was easy to understand. I don't have any kids of my own. My cousin has young children, the oldest is just turning 7 in a few weeks. I think concepts like the sum of an infinite series might be a struggle for her at that age, but it would be very interesting to see what she and her brothers make of it. email is in my profile.
