Thoroughly revised and updated, the second edition of Volume III explores the contexts for ELT curricula; explains key processes in curriculum design; and sets out approaches to curricula that are linguistic-based, content-based, learner centered, and learning centered. Organized around the three pillars of teaching-planning, instructing, and assessing-chapters in the second edition are updated to include current research and theory to meet the needs of today's teachers, and feature new or revised vignettes and activities. New chapters help teachers understand both the technological and multilingual approaches that learners need to succeed today.
