Using technology to increase effort !

In my eco class in school, we are using an online tool called Aplia to turn in our assignments. It's a pretty cool tool (hey that rhymes, unintentionally, though !). There's all sorts of geeky stuff to play around with... Price elasticity of demand, income elasticity of supply, curves that shift, but don't move, and still more curves that move, but don't shift. Anyhow, you get the drift.. Stuff that can keep an economist up at night !

The website is pretty neat. Another one of the cool things we're doing here at IE. But what really beats me (as opposed to all the problems that are posted on Aplia, that also beat me) is this : "Aplia is a learning solution that increases student effort blah-2".

What ? Double check !! Did I get this right ??

On reflection, it appears so. As they'll teach us in some Marketing class in the future, this website is targeted at the academic community, not us, the end-users.

Increasing student effort ? Awesome !
Just kidding here ... the website is pretty cool !!

PS: Pardon me, but in plain and simple English, if a thing 'moves' or if it 'shifts', aren't these one and the same? These things should've been simplified a long time ago !
