This report, released this October, seems pretty interesting. Any publication that has this paragraph in its introduction has already won me over:

Better teaching, in the long run, will come not just from attracting a strong pool of talent and giving them boosts in pay, but from changing the nature of the job. And the teaching profession is in many ways defined by the way schools are designed. Today, most teachers’ work is isolated and fragmented, with no defined pathways for career development, few mechanisms for feedback, and a schedule that is disconnected from the reality of what teachers actually do and what students actually need. As a result, many schools are insufficiently attractive to talented professionals, and they squander the talent of those they manage to employ.
