Today's diverse classrooms include students who have a wide range of previous academic achievement and different levels of receptive and productive proficiency in the language of instruction. Complex Instruction (CI), a popular pedagogical approach used in many countries, provides access to learning opportunities for all students. Designing Groupwork, Fourth Edition incorporates current research findings with new materials on how to implement the specific conditions necessary to ensure that CI strategies reach their expected goals of equity and excellence. This updated edition addresses new classroom technologies that impact teaching and learning; challenges that arose from the global pandemic; and students' vulnerable social-emotional states. Readers will learn how to respond to challenges and organize their classroom so that all students participate equitably. This classic text remains a valuable and sensible resource for educators in K-12 classrooms, for teacher candidates, and for anyone working in the field of education.
