The present study addresses the question how Go for it!, a textbook developed on task-based
language instruction mode, treats language forms. Tasks and activities from a sample unit in
Go for it! are analyzed to examine whether and how textbook writers incorporate a Focus on
Form in the task and activity design. The results show that equal emphasis is laid on both
meaning and form, and three major types of Focus on Form tasks and two types of Focus on
Form activities are identified. The study may contribute to textbook designers and teachers
in treating the issue of how to design Focus on Form activities in task-based language
teaching.
