Originating from a genuine need of the secondary school teachers of English in Hong Kong to understand what it means to implement a task-based curriculum in the English classroom, this book aims to support and empower frontline ELT teachers in implementing a task-based approach systematically without losing sight of the importance of grammar teaching within the framework of tasks. Useful examples are provided to illustrate how grammar teaching can be conducted through meaningful tasks in authentic contexts. The importance of viewing assessment as an integral part of the learning, teaching and assessment cycle is also discussed with practical suggestions on developing assessment tasks and assessment assessment criteria provided. In the form of a self-learning package, this book can be readily used for independent self-study or as a school-based staff-development programme run by teachers themselves. Student-teachers of English, teacher educators and curriculum developers will also find the book a very useful reference guide to learn about ELT task-based curriculum planning, grammar teaching and assessment.
