We have groups of not bigger than 4. Small enough to allow for active participation needed to become an experienced speaker, as well as for keeping the teacher's care and attention less divided.
Our groups are composed and not knocked together. We do personal interviews supplying us and our students with sufficient information to sit back and look forward to new developments.
We learn about our student's oral language skills, goals and how we can help the cause. We get to know our interviewee as a worker, a language user and as a human being.
Our student learns what he can expect and may tell us about his prior experiences.
