This might be the most explicit link to constructivism and constructionism. Not only is it about “learn by doing”, but it’s about concrete action in the physical world. Can’t help but find it limiting and restrictive to mention “3D Printing” as the main component. After all, FabLabs got started without 3D printers and the Maker movement has a lot of stuff which has little to do with 3D Printing. But it’s hard to argue that 3D Printing haven’t attracted attention, in the past couple of years. Sexier than laser etching? As Makers often point out, there’s a lot in the movement which is really very similar to what was happening in shop class. Though the trend may sound new, it’s partly based on nostalgia. A neat aspect, though, is that much of it can happen through learners’ projects cutting across class boundaries. Sure, we’ve known about project-based learning for a while. You do a project for a class or a series of classes. But how about a personal pathway (cf. “individualism”, above) through which learners add learning experiences around a central project? Learning Circles can make that into something really neat.
