Replace Sec. Ed. Arne Duncan with Prof. Diane Ravitch, as Duncan's ed advice to Obama hurts more students than it helps

If President Obama truly desires to provide all students with access to the best public education possible, and concurrently to energize teachers as an important voting bloc in his re-election campaign, he should replace Sec. of Ed. Arne Duncan with Prof. Diane Ravitch, or someone else not beholden to corporate interests, such as Prof. Linda Darling-Hammond, Prof. Yong Zhao, or similar. Duncan's current ed policies align more with corporate interests, and those interested in privatizing K-12 education, than what parents, students, and teachers know to be best practices. Let neurocognitive research on how students learn best, along with experts in the field determine how best to teach our nation's students, rather than ed reform wannabes with little to no experience teaching children.
