What is an effective technique for teaching English as a foreign language to adults?

i think people would think that teaching adults is quite difficult than teaching young learners ..
guess what? it is wrong but the opposite is not also true ....
teaching young learners complicated forms and correct grammar would be difficult since thier congnitive understanding is not complete yet ; However, young learners would be fast in learning new words and especialy learning a correct articulation while adults will be fast in learning complicated grammatical forms and tenses and they would be slow in memorizing new words and having correct articulations for words ...
so u can adapt ur way of teaching according to the informations i gave u .l

you must use a recorder to hear the items and make them solve exercises read the lessons and make them explain some compositions and make converstion between them

There is no one effective way to do that.
Adults are harder to teach compared with kids so that you need to be more formal and strict with teaching them.
It's not at this level to start from the very beginning or the Alphabets; it's gonna be tiring.
So just teach them the way you believe its good with them

Setting points for discussion makes adult students selfconfident.
We can use the points to attain our objectives wether they are grammar reading or writing.

Communicative approach, listening

TEFL for non Arabs because they communicate using one language but what we can use is TESL

ther is not astrict technique to teach .
you have to be creative every time because pupils can get bored.any way i think role playing,co-operative learing ........and previewing lessons is very useful.

I think listening is the best way to teach English language.
listen to Foreign language like songs, movies, or chat with foreign.
and translating it`s very good way to teach English.

I do agree to the notiont that it is difficult to teacher EFL to and adult, remember 'it is difficult to teach an old dog new tricks, but you first appreciate those tricks and in the process improvising to adapt the to the new ways . The catch however is to appreciate the fact that our thoughts are always in our mother tongue and hence the need to make the learner know that and not to be ashamed as this becomes a hinderance to the thought process which eventually leads to an answer being aired out. thus making the learner appreciate that builts confidence and boosts the though process. Whatever difficulty task at hand, remember that our task is to create an environment that is conducive for learning, lets 'brunerise'

To teach is to teach.
It depands upon your techniques.
You can always use the same way of skilles you teach the youngsters.
Do not let them feel that you are making fun of them while doing that.
always lough with them incourage them to read and write even like a child.
A human being alawys needs imotioms in all ages.
Ofcourse you have to consider the ages.

To get them involved and responsible.
