I think billionaire Bill Gates’ foundation wasted $50 million on a myopic study, researching the classroom performance of 3,000 teachers [“Group: Missteps in Common Core,” News, May 27].

That money could have been better spent supporting teachers, instead of trying to quantify an intangible craft. Students are not widgets, teachers are not automatons.

Supervise teachers, observe them often, listen to their needs, consider parent input, and you will have an effective formula for rating pedagogues. To spend that obscene amount on research instead of education is a travesty.
