Up until this point I have been making my own materials to use with students. Since, I've only been doing one-on-one tutoring this has been easy enough. However, I am now going to start teaching group classes and would like to use a textbook that each student can either purchase or be assigned homework from. I teach Adults, beginner to intermediate. I am overwhelmed by the variety of textbooks out there.
The university bookstore near me carries at least NINE publishers, I spent yesterday looking at over 20 books and I could see good ideas in all of them.
I'm sure this topic has been discussed to death already. (Yes, I did search
) But thought I'd ask you most knowledgeable ninja teachers what your favorite textbooks are.
