writes "If you don't have kids of school age, you may not be aware that Data Walls — typically a low-tech "dashboard" of color-coded sticky notes on a wall bearing the names of pupils to highlight their achievement level, absences, or discipline problems — are apparently quite the rage. This is much to the chagrin of some teachers, including Peter A. Greene, who rails against the walls-of-shame in Up Against the Data Wall. Why stop there, Greene asks, tongue-in-cheek. Why not have data-driven dress codes? Data-driven recess? Pooh-poohing concerns of teachers who think Data Walls are mean but feel pressure to create them, the Supt. of Holyoke Public Schools said, "It's not a mandate whatsoever." Still, he went on to add, "I would say 99 percent of teachers see the benefit of it," which some might take as an implicit mandate. In other student privacy news, New York's Supreme Court has ruled that parental permission is not required to disclose student data to the Bill and Melinda Gates Foundation-funded inBloom, perhaps paving the way for the Great Data Wall of the U.S."
