A brave or, more accurately, foolhardy attempt to marry Bloom's (unempirical and unsubtle) taxonomy and the (equally unempirical but worthy of reflection) SAMR model of technology that categorizes technologies in terms of relative transformative capacity, with examples of appropriate iPad tools to cover each segment of both wheels. Like most such models, it is way too neat. You simply cannot categorize things that relate to the complex world of learning in such coarse and simple ways - in both the case of Bloom and of SAMR, it ain't what you do so much as the way that you do it that makes all the difference in the world, and the tools linked to are mostly much more interesting (and, conversely, much more boring) than the diagram suggests. However, like many such models, it is not a bad bit of scaffolding or at least a springboard for reflection that encourages one to think about things that, without it, might be missed, especially if you are not an expert in pedagogy or technology.
