Knowing how to identify and measure great teaching is a huge step toward providing better feedback and support for teachers and building a better education system for all our children -- but it's just one step.
Hearing exactly how each note is meant to sound makes it easier for students to master musical basics during the beginning stages of their educations, providing instant feedback for those that depend on self-teaching.
The foundation and others have estimated that it could cost between 1.5% and 2% of the overall budget for teacher compensation and benefits to implement a feedback and evaluation system based on multiple measures of teaching performance.
Starting in 2009, the Gates Foundation supported a project known as the Measure of Effective Teaching, or MET, which worked with 3, 000 teachers to come up an evaluation and feedback system that helped teachers improve.
