Learners who engage in extensive reading do so for the pleasure of it as well as to improve their overall reading abilities. It's comparable to intense reading, which is reading in depth with specific learning objectives and tasks in mind. Extensive reading is sometimes ignored, particularly in the classroom. Teachers frequently believe it is a waste of class time or are simply uneasy with the prolonged quiet. Setting up a class library, promoting review writing, including book reading into the syllabus, and allocating some class time to silent reading are all ways to encourage students to read widely.
