Sách/BookAuthors: Jerry Greer Gebhard (2017)
This third edition is an ideal teacher development text for pre-service and in-service EFL/ESL teachers, as well as a guide for those who find themselves teaching English overseas but who do not have a master's in TESOL. This edition has the same three major sections as the previous edition: Self-Development, Exploration, and Settings; Principles of EFL/ESL Teaching; and Teaching Language Skills.
