With increasing numbers of students receiving gifted services every year, it is more important than ever to make certain we are meeting their unique learning needs in the classroom. Differentiated instruction for these learners must go beyond adjusting content levels, task complexity, or product choice--it must truly challenge and support learners on all levels: academic, social, and emotional. A leading resource in the field of gifted education, this book connects the unique learning differences among gifted students to the specific teaching methods used to tailor their learning experiences. Expansive new content in the revised edition includes: (1) a discussion of underserved learners--particularly English language learners, students with autism spectrum disorder (ASD), and economically disadvantaged students; (2) updated information on learning standards, MTSS, and universal screening; (3) new guidelines for honors courses; (4) a focus on scholarly questioning, ethics, and empathy; (5) a novel new strategy to increase curricular depth and complexity; (6) information on learning orientations; (7) new research on neurological differences of gifted learners; (8) the pros and cons of co-teaching and how to assess its progress; (9) new tools to increase achievement, plus a discussion of "underlearning"; (10) the benefits of coaching and lesson study; and (11) the authors' perspectives on and guidelines for grading. Downloadable digital content includes customizable reproducible forms and a PDF presentation; a free PLC/Book Study Guide for use in professional development is also available.
