Unlike freewriting, learners need to edit their work. You should provide a topic or visual stimulus (full page magazine pictures work well) and circulate among the students as they write. By allowing time to write during the lesson (as opposed to homework) you give them a chance to ask you questions and refine their work. You can also have learners pair up to read each other's work and make suggestions. At the end, ask learners to volunteer to read their compositions to the group, but be careful about requiring everyone to share. You can customize your topic to practice specific English forms. For example, ask past/future questions to work on verb forms, or practice prepositions by showing a picture of a room and asking learners to describe the locations of all the objects they can identify. You may also ask advanced learners to summarize and respond to a brief reading passage.
