English classes for grown-ups are always fun. Usually, the levels are divided into elementary, beginners, pre-intermediate, intermediate, upper-intermediate, advanced, proficiency etc.
The problem is that not everybody in a group has the same knowledge of English, so in an elementary class you may find people who know some English ( they’ve studied the language in school) an people who don’t know how to say ‘ I’; also, people are different and their abilities and motivations to learn the language differ.
So, I think it’s a good idea to re-organize the groups, after a few sessions, into :
-talented, but lazy
-untalented but perseverant
-untalented, neglectful, but stubborn
-English through signs ( for those who are afraid of speaking in English )
-talented, but neglectful
-talented and perseverant
-talkative ( not necessary accurate or to the point)
-future English teachers ( for those who cannot keep themselves from correcting the others)
