The document discusses tasks in language teaching. It defines tasks according to Richards et al. (1985) as activities carried out through language processing or understanding, and may or may not involve language production. Tasks should have a clear objective and require active language use. The document also discusses the differences between task-based language teaching (TBLT) which uses unfocused tasks to provide communication opportunities, and task-supported language teaching (TSLT) which uses a structural syllabus with practice tasks focusing on form rather than meaning. Finally, it describes the presenter's evaluation of tasks in an English textbook unit with a classmate, where they analyzed tasks by type, skill, and placement to understand the pedagogical purpose.
