I feel this is a good starting needs assessment form for students to fill out in a class

Thoughts on TESL

With the little I've read and done so far I keep coming across people mentioning only correcting English language learners based on ability and their confidence level. We are hired to teach them how to speak a given language properly, not give them a half education. Is it not a teachers responsibility to teach students properly? If they "sort of" get it did we not fail then?
