Teaching english to multilevel classes

1.2.The Struggles of Multilevel ESL Classes
Experiment with different types of groupings to find the ones that work best.
You may find that cross-ability pairs work best for certain types of activities, while like-ability small groups work better for others. If possible, use a wide variety of groupings to keep things interesting for your class.
Use a simple schedule that is similar each day.
Here is an example:
Start with a warm-up that involves the whole group.
Break part of the class off into one type of grouping (i.e. pairs) and work with part of the class on a lesson, grammar point, or activity.
Break off the class into another type of grouping (i.e. small groups) and have the other students use self-access materials.
Bring the class back together for a whole group activity/game.
Isolate students within the class who are interested in peer tutoring.
This doesn't have to be the student with the highest level of English. Your students who fall somewhere in the middle may in fact be the most valuable to you, as they strive to attain a level of competency comparable to the most advanced students. Remind your students that the best way to practice and improve a new language is to teach it to someone else.
Consider enlisting a volunteer.
Limited budgets or low enrolment are often the reasons behind multi-level classes. For this reason, it may be difficult to convince administrators or managers that you need a paid assistant. If you feel overwhelmed, consider hiring a volunteer. Finding someone who is interested in helping you with your preparation work and teaching may not be as difficult as you think. Most native English students who are going into the teaching profession will be more than willing to put in volunteer teaching hours in exchange for a reference. Once you have permission from your supervisor, you can post an ad at the local library or college, or at a teacher training centre. You may even want to suggest placing an ad on the website for the school you work at.
