While you should not participate in pair or group activities, you need to stay involved in what the students are doing. One important reason to circulate during activities is to keep track of the kinds of problems students have, such as grammatical accuracy, fluency, word choice, pronunciation and intonation discussion strategies, etc. However, it is generally not effective to correct students' errors when they arc involved in an activity. The most practical way to deal with communication problems is to make notes of what you observe as you arc circulating. You can then use this information to provide feedback after the activity or to develop future lessons.
