Having gone through 2 major projects now to produce open educational resources (OER) from scratch, I know what it takes! We produce, source and aggregate all the different pieces together, whether it is text, illustrations, photographs, videos, simulations, concept maps, or all of the above. The result is a complete package, under an open license, for a specific purpose or context.
As part of the Learning Creative Learning course that I am doing, run by the Lifelong Kindergarten group at MIT Media Lab, we were introduced to Scratch. We were encouraged to create our own project to introduce ourselves. Scratch was developed by the Lifelong Kindergarten group (love that name!), as it is their mission to develop new technologies, looking back to kids for inspiration, thus expanding the range of what people can design, create and learn. And Scratch certainly achieves this!
I actually really enjoy making concept maps. I find it quite a satisfying process to take several pages of content, a whole chapter, or a curriculum document, and present it all on one page, showing the links and creating an overall, cohesive graphical representation. And, of course, adding a dash of colour.
