Based on extensive research, this book is filled with illustrative, down-to-earth examples of how classroom assessment works in classrooms where assessment drives the instruction. The authors present the Classroom Assessment Cycle—Clarifying learning targets, Collecting assessment evidence, Analyzing assessment data, and Modifying instruction based upon assessment data—that demonstrates how one assessment action must flow into the next to be effective. Each chapter details the kinds of assessment evidence that are the most useful for determining student achievement and provides instruction in the analysis of assessment data.
