The POWERSOURCE[C] intervention is intended as a generalizable and powerful formative assessment strategy that can be integrated with any on-going mathematics curriculum to improve teachers' knowledge and practice and, in turn, student learning. Combining theory and research in cognition, assessment and learning (for both adults and students) with…

This paper will describe the relationships between research on learning and its application in assessment models and operational systems. These have been topics of research at the National Center for Research on Evaluation, Standards, and Student Testing (CRESST) for more than 20 years and form a significant part of the intellectual foundation of…

In this study we explored the effectiveness of individualizing instruction using a system that diagnosed students' knowledge gaps in pre-algebra and provided individualized instruction and practice. One hundred middle school students participated, and received either no instruction or individualized computer-based instruction. Diagnosis of…
