Props to Chris Dawson over at ZDNet who got me digging what Wolfram Alpha can do for me and my alternative students when it comes to math (see Need help in math? Try Wolfram Alpha here).
I remember reading several blog posts earlier this year heralding the arrival of this math/science based search engine, but I tabled any real investigation. Until I read Dawson’s post and considered the ramifications for alternative and remedial teachers, in particular those with access to an interactive whiteboard (IWB).
First, remedial and alternative learners share the fact they don’t always track the traditional problem-solving steps. Consider traditional algebraic teaching models – write the problem, follow prescribed steps, repeat, repeat until memorized process ingrained in student DNA. In the case of an alternative learner these students actually need to see the answers first, layer a map of the process over this solution, then return to another problem, identify the steps they just saw, then solve according to those steps, then, attempt the problems either on thier own, or against the silhouette of the process map.
Whew! No wonder these kids give traditional teachers fits, and traditional processes give these kids fits.
Enter the wonders that are Wolfram Alpha and your IWB.
Before continuing, let me state I believe the value of the IWB is not in it’s software, though there are many, many powerful and useful tools bundled by manufacturers; instead, it the strength of the IWB rests in being able to open a window to an entire class of students to enhance their understanding. (need convincing head here, afterfinishing this piece of course)
So, in the midst of an aiding my alternative students with their mainstream algebra unit, thanks to W/A I now have the capacity to re-teach material as my students learn best.
“Schlegs, what does it mean – solve 6x+8?”

Point, click, solve
No so fast, critics who say this merely gives an answer. Remember, these are kids who likely need to see the entire big picture before they see the pieces.
So, I can select “show steps”, and there are the steps to follow.

What are the steps to solving this equation?
The IWB offers a window into this, but even better is how I can use a screen/image capture tool to import the search result into my flipchart, notebook, etc., and then annotate before the entire class. The steps, already there, are ready for analysis and identification. Better still, I retain a digital copy for future reference when needed. And, as we add layers to basic problems, we can repeat the process, and then compare/contrast basic problems with more complex ones.
Surely, this is one wolf that could keep alternative learners off our schools endangered species lists.
