Summary
Summary
The POWERSOURCE© intervention is a formative assessment-based strategy that can be integrated with any ongoing mathematics curriculum to improve teachers' knowledge and practice and, in turn, student learning. POWERSOURCE© includes both a system of learning-based assessments and an infrastructure to support teachers' use of those assessments to improve student learning. The Year 5 study focused on middle school mathematics, starting in Grade 6. Of the two teacher knowledge measures used, the teacher knowledge maps provided clearer information about how the POWERSOURCE© intervention affected teacher knowledge. Our findings indicate that POWERSOURCE© professional development helps teachers become more expert-like in the way they think about math problems in relation to mathematical concepts.
