Popular crustaceans like lobster, crabs and prawns owe their success to a unique colour control system, according to a new genetic study.

Programming -OK, on the programming thing, here are my thoughts.In our curriculum our objective is not as much a specific LANGUAGE. One year I may use HTML with Javascript, this past year I used LSL — what I want kids to know that when they encounter programming and coding that there are certain conventions. Some are case sensitive, some are not. How do you find out how to add to what you know about programming? Do you know where to go to find prewritten code? Can you hack it to make it work to do what you want it to do?We spend about a week – two weeks but I require they know how to handcode hyperlinks and images – they are just too important.But to take 12 weeks or 6 weeks to learn a whole language – yes maybe some value – but to me the value is HOW is the language constructed or built. What are the conventions and how do I educate myself if I am interested in pursuing. What comes out of this time is kids who say either “I never want to do that” or “this is really cool, I love coding.”They are doing very simplistic work (although the LSL object languages were pretty advanced) but since we don’t have a full course nor time in our curriculum, I do see this as an essential part of what I teach.I’m not teaching it for the language sake but for the sake of understanding the whole body of how languages work – we talk about the different languages and what they are used for as part of Intro to Computer science and have an immersive experience.To me, this is somewhat a comprimise between leaving it out entirely or forcing everyone to take 12 weeks of it. I just don’t know where 12 weeks would go in the curriculum.

It’s a step backward. A 1:1 classroom done at least fairly well becomes a an intense learning environment. Students are engaged, empowered, active learners instead of sitting learning to be taught. It is an active process a far greater amount of the time (and this is one area I need to improve, is getting that and letting that happen more) and the feel of the classroom changes. People that visit pick up on that. It changes from a 1:1 laptop classroom into a learning environment that uses laptops and other tools to leverage learning.
