Dear Nounou,
The first question that I would ask is: �Have these Students been correctly assessed before it was decided to put them in this Class?�
Assuming that the school/college has a proper entry procedure, the probable answer is: �Yes!�
Then, it would be necessary to discover the weaknesses, (and strengths), of each Student. It is rare for a Student to be weak in all four disciplines of language: Speaking; Listening; Reading; and Writing.
I would assess every Student to ascertain the level of competence in each of the 4 disciplines, trying to discover what the specific weakness of that Student is in, for example, Speaking.
With this knowledge, it becomes possible to group Students together, giving each group a learning task appropriate to the language deficiencies of Students in that group. I would begin with their most obvious deficiencies, and then move on those that were less important.
My first Lesson would concentrate on boosting the confidence of the Students, so as to increase their motivation to learn English. Many low-level Students have low self-esteem and they are convinced that they cannot learn. Their self-confidence, self-belief, and self-pride MUST be restored so that they see a new, exciting life in front of them, full of promise. Only then will they have a real motive to learn. Once they are motivated to learn they have the opportunity to succeed in their ambitions. Once they succeed and achieve their ambitions, their lives will be changed.
You will find some of my thoughts on motivation here.
I hope that I have helped you.
