1) IT MOTIVATES STUDENTS TO WORK FACE TO FACE ENCOUNTERS IN THE CLASSROOM
Students are much more interested in these speaking activities that resemble real-world communication because they are more meaningful for them. As teachers, we should always include them in our lessons; for example, we can give them games, quizzes or any information-gap activity so that learners have the need to express themselves.
Of course there are ways of practising speaking that do not involve dividing a class into groups, but they are not as engaging as a pair or group-work activity.
2) IT INCREASES OPPORTUNITIES FOR PRACTISING THE LANGUAGE.
Students have more chances to practise the foreign language in this case because there are a few students working in a speaking activity. This is the only tool we have when we teach large courses as we can make sure that they all participate in the task.
3) IT GIVES STUDENTS THE OPPORTUNITY TO MONITOR HOW WELL THEY UNDERSTAND AND ARE UNDERSTOOD.
By interacting with their classmates, learners get to know how they are doing in communicating. It is also a good idea to mix our students so that each time they can interact with someone new. This will bring them more opportunities to learn other words and strategies to express what they want to say.
