What is Extensive Reading, and how can we help students get started? What should they read, and how do we build and look after a library that will help them improve? How can we check if students are reading and making progress, without taking away the freedom that ER gives? This practical workshop gives an introduction to ER for teachers new to the approach. It also offers ideas for experienced practitioners who are looking for effective ways to introduce ER to their students, colleagues, or institutions. We will look at a range of rationales for ER including fluency development, vocabulary growth and affective benefits, and discuss how these can be communicated in different teaching contexts. The attendees will also share ideas about text selection, library development, assessment strategies, and the role of the teacher in an ER environment.
