Why assess? And what will I do with the results? This book examines classroom assessment (not standardized assessment) through the lenses of three ESL teachers from across the United States. The teachers face a number of challenges particular to their individual situations, and other challenges common to all U.S. public school teachers. Most important, this book views teachers as the people best able to make their students successful. The decisions they make about assessments in the areas of literacy, oral language, and content-specific language development result in actionable information. Short reflections, jargon sidebars, and chapter activities make this an enjoyable, user-friendly resource for teachers in any classroom.
