If I have to hear the word "DATA" one more time...

I have all the 'data' that I need. It's in the understanding or confusion on the kids' faces when we teach. It's in the work they complete and I check. It's in their quiz grades and test grades. It's in their lab data sheets. In other words, my gradebook. why should all (or any) of that be on the wall? I'm with Carolyn on this.  http://www.washingtonpost.com/blogs/answer-sheet/wp/2014/02/14/how-data-walls-in-classrooms-can-humiliate-young-kids/
