Issues in Second Language Teaching is a text-book written in order to help trainee teachers and more experienced teachers reflect on certain topics related to second language learning and language teaching. It provides readers with a better understanding of the interface between second language learning theory and research, and language teaching practices. The main objective of the textbook is to develop and enhance readers theoretical and practical understanding of how teachers should approach the way they teach languages in the classroom. Readers will be asked to reflect on the implications of second language learning research and theory on language teaching by providing an analysis of how the principles derived from research can be applied in the language classroom when it comes to issues such as teaching grammar, correct errors, provide good input, develop output activities or encourage interaction between learners. The textbook does not support a particular methodology for language teaching but focuses on specific themes in relation to language teaching.
