This highly practical guide shows pre-service and in-service educators how to use a process of diagnostic teaching to make sophisticated diagnostic and assessment judgments and identify appropriate instructional techniques. Here is the ideal resource for use in reading practicumsor in reading clinic experiences; as a core text for Reading Assessment, Diagnosis, and Differentiated Instruction courses; and as a helpful reference for reading specialists, literacy coaches, school psychologists, special education teachers, and Title I teachers. In it, educators see how to use a variety of instructional and assessment techniques to help plan lessons designed to improve literacy for all learners in their charge. Included are descriptions and explanations of the steps of over 65 instructional techniques which include adaptations for struggling readers and writers, English language learners, and culturally diverse learners. Teachers see how to use this knowledge to make informed instructional decisions that lead to a renewal of their decision-making power. The instructional techniques are written in a step-by-step manner, making it easy for reading specialists and teachers to evaluate when and how they adapt their instruction. Included for each are descriptions, step-by-step procedures, and detailed information on how and why to use the technique. The goal, says highly regarded author Barbara Walker, is to increase communication between the practitioner and various specialists as well as between the practicum student and the college professor.
