I'm looking for recommendations on an ESL curriculum. Rather than just one textbook, I'm looking for perhaps a series of textbooks that takes a student from absolute beginner to advanced. (or at least intermediate).
The one good example I've seen of this are the Callan books--they take you through everything, teacher texts, student texts, exams--but they are taught with the Callan method. I'm looking for a similar package that uses a different methodology.
Does anybody have a recommendation for something good they've used before? Thanks!
Curriculum
Moderators: Dimitris, maneki neko2, Lorikeet, Enrico Palazzo, superpeach, cecil2, Mr. Kalgukshi2
