Recently I tweeted the above image and within a single day it was retweeted and liked over 2000 times.  That’s something.  Could you imagine if your students tweeted something from your lesson to this extent?  Or if your principal or employer gave you that many kudos for something you shared?  Needless to say I think the notion the image suggests around the role of data in education struck a chord with my PLN and I’d like to take this opportunity to grapple with why I think this is the case.
