Lessons on Using Data for Assessment From A Football Game

via NY Post
The last couple of days, I've been a little bit down, emotionally. I'm a Packer fan, and an "owner," and I was coming to grips with the fact that the team had thrown away a great chance to advance to the Super Bowl in one of the most epic collapses in NFL history. 

As I perused some of the articles written about the game, I was startled to see the statistics from the two quarterbacks in the game, the Packers Aaron Rodgers, and Seattle's Russell Wilson.



QB Ratings for NFC Championship

One of the ways that quarterbacks in the NFL are evaluated is by Quarterback Rating. This rating is based on a complicated formula involving Completion Percentage, Yards Per Attempt, Touchdowns and Interceptions. While some believe that the formula is flawed, it has been used for many years to evaluate a quarterback's performance.

Based on this generally accepted formula, neither quarterback had a very effective game. In fact, Wilson had a 0 for a rating through most of the game. Still if you used this formula, it would appear that Rodgers played close to 4 times better than Wilson based on the statistics. Despite this, Wilson's last three passes resulted in a 2 pt. conversion, a key 3rd down reception, and a touchdown that won the game for his team. 

This got me to thinking about how students and teachers get evaluated. Some teachers complain about the student who coasts all semester, only to turn it on in the last few weeks to pass the class. They want the grade to reflect that "lack of effort."
Others want to evaluate teachers based on standardized test scores of their students, despite research that questions the correlation. 

Based only on the statistics, it appears Rodgers had the better game. But I think he'd take Wilson's numbers if it meant he'd be playing in the Super Bowl in a few days. 

There are some flaws to this analogy, but I hope it encourages people to think about the data they use to assess students and teachers, and how sometimes, numbers don't tell the whole story.

We Have Met the Enemy and He is PowerPoint! A Reflection

Today, the New York Times ran an interesting article regarding the use of PowerPoint in the military, We Have Met the Enemy and He is PowerPoint . It was a fairly damning critique of an organization that gets most of its information or lack of information through PowerPoint slides. Here are a few quotes from the article: “PowerPoint makes us stupid" - Gen. James N. Matti “It’s dangerous because it can create the illusion of understanding and the illusion of control...Some problems in the world are not bullet-izable.” -Gen. H.R. McMaster And the following comment that I think has a great impact for us as educators: " Commanders say that behind all the PowerPoint jokes are serious concerns that the program stifles discussion, critical thinking and thoughtful decision-making ." And this... "Commanders say that the slides impart less information than a five-page paper can hold, and that they relieve the briefer of the need to polish writing to convey an analytic, persu...

Syncronicity Regarding the Future of Learning: Are you a Sherpa or a Jazz Musician?

Yesterday, Sara Swenson , Edina High School Librarian (She prefers that term!) shared the following video with me via e-mail that she found on an NCTE Web s ite . I thought that the video crystallized for me the potential for educational technology integration, 21st Century learning and learning beyond the classroom walls. It is something we are working on with our Community of Practice . That isn't to say that there won't be road blocks to navigate, or crevasses to traverse! We know they exist now! I was intrigued to see the teacher's role defined in such creative ways!! When people ask you what you do for a living, do you respond as "teacher", "educator", "instructor", facilitator", or are you a "Connected Learning Incubator" or are you still "Keeper of All Knowledge Which Is Good?" Hmmm ... Then this morning, I checked my Twitter feed and Will Richardson had posted about a conference on the Future of Education ...
