NEWCLASSROOMS.ORG: As EdSurge noted two weeks ago, Joel Rose, ideaman behind School of One, has a new nonprofit afoot: NewClassrooms.org. Once again, he's pushing the edge of school models, with an eye toward turning learning into a deeply personalized experience. NewClassrooms will get started by pulling together a middle school math program ("Teach to One: Math"), which will use both existing and home-grown materials. Joel expects that four to six schools in three cities will try out the program in fall 2012; some schools will get a headstart by using the materials in after-school programs this spring. Chris Rush, who headed School of One after Joel's departure, has also joined NewClassrooms.org. And School of One? New York City has agreed to let NewClassrooms.org manage the program, which is expected to expand to as many as 50 NYC public schools over the next 2.5 years. NewClassrooms.org is funded by the Bezos Family Foundation, the Bill & Melinda Gates Foundation and NewSchoolsVenture Fund.
