YES Absolutely! I actually began teaching with a method called total physical response, which was an kinesthetic method for teaching a second-language, when i discovered WBT I fell in love because I already had the "gestures" part down, but the mirror, teach-okay, and everything else fell into place so wonderfully.
Learning a second language is hard when it's just rote memorization, so activating the students by using their bodies and by having them talk to each other about it is great practice of the language.
Also, when you get more in depth with the WBT techniques and methods, there are lots of sentence frames, etc.
Check out the Whole Brain Writing Game. It's seriously amazing... it will blow your mind... it scaffolds for the students in just teaching them how to write basic sentences to more complex, then to paragraphs etc.
