Intervention Summary

POWERSOURCE © is a formative assessment intervention that targets middle-school mathematics, specifically focusing on key mathematical principles that are prerequisites to mastering algebra. The intervention includes a system of learning-based assessments and an infrastructure to support teachers' use of those assessments to improve student learning. POWERSOURCE © assessments are designed to be short, targeted, and easily incorporated into existing curricula, with a focus on four domains: rational number equivalence, properties of arithmetic, principles for solving linear equations, and application of core principles to other critical areas of mathematics. The intervention also includes professional development for teachers, which provides guidance on understanding student responses to the assessments, teaching activities, and sample scripts to help students grasp key concepts.

Data Sample by Population

These charts show the characteristics of the student populations studied. When assessing programs, you may want to prioritize interventions that yielded success in a similar demographic environment as your school or district.

The subgroup population data as studied here are not available. That means that while this study may work well for your setting, we cannot say based on the published study and results from our system’s reading of that study what the school/district subgroup characteristics were when evaluated here.
