Co-teaching and the PrimeD framework: Radicals and rational exponents. Research report presented at the annual research meeting of the National Council of Teachers of Mathematics, Washington, DC.http://hdl.handle.net/11603/14417This study resulted in professional growth of teachers with regard to empowering students to lead the development of knowledge around concepts and procedures, developing and critiquing strategies and ideas. This approach to teaching mathematics helped the teachers transcend racial divides to give every student in their classes a voice and opportunity to contribute to their own learning and that of others.This study examined the application of a co-teaching model to the PrimeD framework. Two teachers and a teacher educator collaborated to develop, implement, evaluate, and study a unit on radical expressions, equations, and functions in 3 high school algebra 2 classes. Results indicated that this approach to PD can be a powerful way to support the professional growth of teachers and teacher educators alike.11 pagesen-USThis item is likely protected under Title 17 of the U.S. Copyright Law.
