Just for fun!
Every teacher has asked it at one point - how do I teach a multilevel class? It may be true that every class is a multilevel class, which means teachers need to be creative about the ways they handle students' varying levels. One activity that works well is the multilevel dictation, as demonstrated last week at the seminar "Teaching Large Multilevel Classes".
In this activity, the teacher prepares a dictation as normal, but makes two versions - a low-level version, where fewer (and more basic) words are removed, and a medium-level version, where more (or more difficult) words are removed. Students have a choice before the dictation begins - they can choose from the low-level or medium-level versions. They also have the choice to choose a blank piece of paper for more of a challenge.
This activity is a clear example of the student-centered classroom, as the students choose the level they want to work with for the day. The teacher should not interfere in the students' choice - if a lower-level student has decided to go for the blank piece of paper, let him/her do so. The idea is that students exercise their right to choose the level they work at, and in the process gain more confidence about their English use.
