The Center for Outreach in Mathematics Professional Learning & Educational Technology in Virginia is a mathematics partnership between Faculty from George Mason University (GMU) and school divisions in Northern Virginia (Alexandria, Falls Church City, Fairfax County, Loudoun County, Manassas City and Prince William County). Using a blended approach with high quality onsite professional development (through summer institutes and follow up seminars and content-focused coaching through Lesson Study) and GMU Math e-learning Network (content-focused webinars, and video clips align with the 2009 SOL standards), the center will provide sustained, intensive, and high-quality professional development for math teachers, special educators, and teachers of Limited English Proficient (LEP) students that will address needs identified in the school/district professional development plan.
