Continuous formation

One of the reasons we've decided to jump into this CAS process at this point in time is that the new interface is far more student-friendly. We were loath to start with a CAS when the learning curve would be so great. While I know that some would say that the TI is a possibility, it's short-sighted; no one uses the TI software/handhelds beyond highschool. And the hand-helds are a button-intensive, small screen mess. It's a toss-up between Maple and Mathematica - and we have an existing relationship with Maple (it's HQ is down the road an hour). The interface is now far more point & click with no (okay, few) arcane (to students) commands and it describes the step that has been performs. Graphing is a lot easier (you can drag an expression onto a grid and it graphs!) and parameters can be automated with a click. That, of course, is the easy part done. Now, the hard part: what questions do we ask to develop understanding, concepts, algorithms? how do we encourage ...
