Wolfram|Alpha Queries

This is my response to this post by Mr. Morford concerning his view of Wolfram|Alpha.In my Finite Math class this semester, I have been using Wolfram|Alpha a lot.  The other day one of my students wanted to use Wolfram|Alpha to reproduce one of the feasible regions, when all she knew were the corner points.  I told my student to do it directly.  Our first query was 'shape with corner points at (1,3) (4,5) (8,6) and (3,1)'.  Wolfram|Alpha didn't take very well to that. After a few trials, I put in the query:  'polygon with vertices at (1,3) (4,5) (8,6) and (3,1)'…

Using Virtual Tools to Solve Real-World Problems

I recently saw this video come up in my Twitter Feed.  It is about a group of teenagers who are working on a project for Abbott Labs, and the story of their teacher who realizes that after working on this Real-World Problem, that the students will never be able to learn the same way ever again.  Meaning, in the traditional sense, without the technology and virtual tools.  I understand where the teacher is coming from.  But as an educator, I don't think it should take a project from Abbott Labs for us to realize this.  We need to realize this…
