Our K-12 system largely still adheres to the century-old, industrial-age factory model of education. A century ago, maybe it made sense to adopt seat-time requirements for graduation and pay teachers based on their educational credentials and seniority… But the factory model of education is the wrong model for the 21st century….the legacy of the factory model of schooling is that tens of billions of dollars are tied up in unproductive use of time and technology, in underused school buildings, in antiquated compensation systems, and in inefficient school finance systems.

Rethinking policies around seat-time requirements, class size, compensating teachers based on their educational credentials, the use of technology in the classroom, inequitable school financing, the over placement of students in special education—almost all of these potentially transformative productivity gains are primarily state and local issues that have to be grappled with.

These are tough issues. Rethinking the status quo, by definition, can be unsettling. But I know that these discussions will be taking place in the coming year in schools, in districts, in union headquarters, in statehouses, and the governor’s mansion. The alternative is to simply end up doing less with less. That is fundamentally unacceptable.

U.S. Secretary of Education Arne Duncan, proclaiming during yesterday’s American Enterprise Institute conference that the status quo in American public education has to change. Well, it needs more than that: A revolution, not an evolution.
