In this chapter, I outlined some of the ways in which coursebooks have changed through the years, as well as some of the disadvantages and advantages of using coursebooks. I then explained five principles for using coursebook, followed by techniques that show how to put the principles into practice: how a coursebook is organized, ways to prepare for, monitor, and follow up an activity, ways to adapt and supplement what is in a coursebook, as well as how to build a repertoire of one’s own. In the last part of the chapter, we looked at how three teachers prepare to teach using a coursebook.
