The Roots of Low Achievement: Where to Begin Altering Them (Hardcover) (ISBN-13: 9781475849875)

Sandra Stotsky, professor of education emerita, University of Arkansas, was senior associate commissioner at the Massachusetts Department of Elementary and Secondary Education from 1999 to 2003, in charge of developing or revising K-12 standards in all major subjects, teacher and administrator licensing regulations, teacher licensure tests, and professional development criteria. She served on the Common Core Validation Committee from 2009 to 2010 but refused to sign off on these standards on the grounds that they were not (1) research-based, (2) internationally benchmarked, or (3) rigorous.
