Assessment is an essential component of differentiated instruction. Assessing students before, during, and after instruction allows teachers and curriculum leaders to draw from a repertoire of assessment tools and strategies not only to improve student performance but also to help students self-assess and take responsibility for their own learning. The assessment strategies in this book will give teachers and curriculum leaders ready-to-use tools for evaluating and activating students' prior knowledge; continually monitoring learning to provide feedback to students and inform instruction; assessing developmental readiness for new learning among younger, adolescent, and teen learners; assessing learner preferences, cognitive styles, and multiple intelligences; creating flexible learning groups for students to work together, alone, with partners, or in small groups; and creating adjustable assignments for students who are beginners or who are struggling, who are performing at grade level or approaching mastery, or who are performing at advanced mastery levels. This collection of ready-to-use assessment strategies will be appropriate for struggling learners, learners with special needs, learners who are performing at grade level, and for advanced learners. The new edition has been reorganized to be more user-friendly, is thoroughly updated, and includes a generous collection of new strategies.
