Communicative Language Teaching in Action: Putting principles to work is designed as a basic text that demonstrates principles and practices of communicative language teaching and task-based instruction. Its primary purpose is to serve as a guide for second and foreign language teachers in training or for those who have embarked on a new career as language teachers. In particular, these include pre- and in-service teacher education majors, university teaching assistants, and English as a Second Language (ESL) majors and instructors. Furthermore, it is meant to be a resource for practicing teachers in continuing education programs.
