Fearless Peter Greene criticizes economist Thomas Kane for his latest paper, called “Never Diet Without a Bathroom Scale and Mirror: The Case for Combining Teacher Evaluation and the Common Core.”

Kane directed the study called Measures of Effective Teaching for the Gates Foundation.

Greene calls the new study “grade A baloney.” Kane calls for “a massive adult behavior change exercise,” not an easy thing to accomplish.

But Greene writes:

“The bathroom scale image is brave, given the number of times folks in the resistance have pointed out that you do not change the weight of a pig by repeatedly measuring it. But I am wondering now– why do I have to have scales or a mirror to lose weight? Will the weight loss occur if it is not caught in data? If a tree’s weight falls in the forest but nobody measures it, does it shake a pound?

“This could be an interesting new application of quantum physics, or it could be another inadvertent revelation about reformster (and economist) biases. Because I do not need a bathroom scale to lose weight. I don’t even need a bathroom scale to know I’m losing weight– I can see the difference in how my clothes fit, I can feel the easier step, the increase in energy. I only need a bathroom scale if I don’t trust my own senses, or because I have somehow been required to prove to someone else that I have lost weight. Or if I believe that things are only real when Important People measure them.

“Kane envisions the Core and new evaluations going hand in hand, leading to more successful implementation of the Core (he does not address the question of why a successful Core is a Good Thing, Much To Be Desired). And his vision of how evaluation will provide a connection to standards as well as the kind of continuous feedback by people who don’t know what they’re doing and whose judgment can’t be trusted.”

Kane says that one of the big problems in American education is teacher autonomy. He believes that teacher work must be carefully monitored, guided, and measured. He refers to Japanese lesson study as exemplary, but does not mention Finland, where teachers are highly prepared, then given considerable autonomy to do the work they were prepared for.

Greene says:

“My experience is that every good teacher I’ve ever known is involved in a constant, daily cycle of reflection and self-examination, using a rich tapestry of directly-observed data to evaluate her own performance, often consulting with fellow professionals. It’s continuous and instantly implemented, then instantly evaluated and modified as needed. It’s nimble, and it involves the professional judgment of trained experts in the field. That seems like a pretty good system to me.”
