Gary Rubinstein took a close look at the new Gates’ study of teacher evaluation and says it is wrong. The media takeaway is tat in evaluating teachers, test scores are more reliable than observations. But Gary, who teaches mathematics at Stuyvesant High School in New York City, says it isn’t so.
Bill Gates has put $50 million into finding the ideal way to evaluate teachers.
Gary concludes: “It seems like the point of this ‘research’ is to simply ‘prove’ that Gates was right about what he expected to be true. He hired some pretty famous economists, people who certainly know enough about math to know that their conclusions are invalid.”
