" think it's pretty safe to say that almost everyone on the Internet these days has heard of Wolfram|Alpha, the "computational knowledge engine". It's a pretty fascinating, not to mention handy, website. You simply type in your query, "population of Argentina in 1980" for example, and Wolfram|Alpha spits out the answer. What could be more awesome?!
Well, what if I told you that Wolfram|Alpha also makes desktop PC and mobile applications that, for all of the notoriety that their's websites received, I've hardly ever heard anyone talk about? And what if I told you that most of these apps were specifically designed with certain subjects in mind, such as statistics, geography, and chemistry? I don't know about you, but I'd be intrigued!"
Apps that fit into this "understanding" stage provide opportunities for students to explain ideas or concepts. Verbs commonly used to describe this phase include interpreting; restating, retelling, summarizing, inferring, generalizing, comparing, rephrasing, translating, reporting, clarifying, and paraphrasing. Understanding Apps step away from the selection of a "right" answer and introduce a more open-ended format for students to summarize content and translate meaning. SWEET
