The Power of Incomplete WODBs

Yesterday I posted the following WODB:

wodb3

I asked “How would you finish this WODB?” and I appreciate the responses I have received.

These are all great answers, and I would tell my students the same when offered.  The one thing I would do is to remind them what makes a good WODB problem and challenge them to create another response with that in mind.

So, what is the Power of WODB? What makes a good WODB problem? The ability to pick any picture and come up with AT LEAST one description of why that one isn’t linked to the other three.  It may be easy to fill in a reason the last image we pick isn’t related to the three posted, but it also needs to support choosing one of the three.  This is something that my students struggle with at first, then they really start examining the problem from a variety of perspectives- many times more than what they engage in with a “complete” WODB.

So, as we typically do in class, reflect on the Tweets I received on the possible missing part.  Do they provide us with a good WODB problem that allows any of the four to be correct? I know my thoughts, I am really interested in yours.
