re: Problem Of Math Educational Software Needs Solution
Hi, geonz, sorry to be so long getting back to you.

Yes, for the most part, "strategy-teaching" software either is software with a hint about trying one strategy, or it's actually strategy-executing, i.e. it doesn't consider which strategy is best, it asks the student to pick one and then executes it for the student. But RAND's work 25 years ago clearly showed that it was possible for a machine to teach strategy -- in exactly the way that machines do all the time, nowadays, for various gaming programs.

re: Problem Of Math Educational Software Needs Solution
Almost all computer based instruction I've seen has been extremely procedure-based, despite all kinds of research indicating a desperate need for instruction that develops concepts and addresses misconceptions (including http://pact.cs.cmu.edu/koeding... ). Much of what's described here seems to be (I'd love to be wrong!) breaking down the same procedural approach into smaller steps and encouraging "thinking" about what step to take next.
For some reason people confuse this with understanding math, assuming that the Enlightened Few will figure out the concepts and the rest will have a better chance of passing their course (and then forgetting everything). Why not start with a conceptual base?
http://mathmistakes.org/?p=117... shows several student responses to a pre-instruction survey about multiplying polynomials indicating the misconceptions students bring to the stage. What can we do to address that instead of drilling on a procedure to get a passing test score? (See http://www.learner.org/resourc... for how smart people have pretty basic misconceptions about basic science)

The Business of Going Digital
Digital business isn't about changing code; it's about changing what legacy sales, distribution, customer service, and product groups do in the new digital age. It's about bringing big data analytics, mobile, social, marketing automation, cloud computing, and the app economy together to launch new products and services. We're seeing new titles in this digital revolution, new responsibilities, new business models, and major shifts in technology spending.
