This document provides guidance for an assignment to design language teaching materials focused on developing language skills. It instructs students to choose an authentic text and associated tasks to develop both receptive skills (reading and listening) and productive skills (writing and speaking) for a specific group of learners. It emphasizes that tasks should be tailored to the learners' level, interests, needs and timetable. Examples of authentic materials are provided, such as newspaper articles, song lyrics and video clips. Background reading on teaching language skills is recommended, and common reasons for assignment resubmission are outlined.
