Actually, I stopped using course books in 2009 – Wow! that’s already more than 10 years ago. For standardized tests such as TOEIC or TOEFL iBT, however, I still use textbooks because I think the students need practice doing sample questions, and get valuable opportunities to learn from their mistakes in simulated questions.
There are two main reasons that I stopped using course books. First, I found that the level and the content was perfect for about 10% of the class, and either too difficult or not challenging enough for the other 90% of students. Furthermore, the topics were often written for an international audience and simply not very interesting or engaging for my EFL students in Japan.
The bigger reason that I gave up on course books was that I thought that I could do better choosing materials on my own. Through the Internet, the world is literally at my finger tips. I spend a lot of time getting to know my students at the start of the year, and then I can easily find materials that are of great interest to them, or materials that are particularly appropriate to the news of the day. Of course, most materials I use are not written for EFL students, but I find that if the contents are interesting enough, they make an effort to derive the necessary meaning from the materials. I always tell them that they are developing a valuable skill by learning to understand what they need to understand from something off the Internet.
Finally, I like to take responsibility for what they study. When things don’t work well enough, I can always try again next time, and online content or materials are endless.
