I take communication courses. During the course I will of course be required to correct grammar and conjugation errors and help fill in vocabulary gaps. I will lead the student to try to maintain a fluid discussion. It's by practicing that we learn :D! I would also suggest some written exercises. However, the student must be able to speak at least English so that we can communicate if necessary. However, in my course we will maximize the time spent speaking in French. I'm going to fazer aulas de communication. During this time, it is clear that you will be able to correct grammatical errors, conjugate and learn to detect gaps in your vocabulary. You encourage others to try to maintain a fluid conversation. In practice it is a good way to learn! You are also welcome to write exercises. However, it is important that some people have English language skills to have our communication, which is necessary. No matter what you do, we will maximize the time dedicated to speaking in French. :D
