Nagel, an international educational consultant, researcher, and former secondary teacher and administrator, provides grading practices that can be used in the secondary classroom, focusing on those that truly impact learning and achievement (rather than tradition and opinions) and practical strategies to prevent failure, recover grades and credits, and increase the quantity and quality of standards-based and standards-referenced grading. He argues for the need for teacher voice in research on grading practices and the use of action research as their basis and discusses how to build solutions for shifting practices from traditional to more impactful ones, why grading changes can be difficult to implement, and what teachers and administrators need to consider when trying to make changes. He addresses issues with school policies, specific practices, and how teachers can conduct action research. Annotation ©2015 Ringgold, Inc., Portland, OR (protoview.com)
