After all, I only want to make students aware and not self-conscious of their problems and mistakes with English. I aim to have all my students speak for the majority of the time. Expressing your opinion is important, but asking a why question will help all your students express themselves. Have ways and means to help your students speak. However there are circumstances when a participant in a group is too tired in which case I leave it up to the person to join in.
Quality time is the name of the game.
I aim to have a light hearted and easy going atmosphere in my sessions. My students have high pressure and responsible jobs. I don't want to add to their stress and pressure in my sessions. Unless things can be organized otherwise, I'd sooner have a group made up of people with common interests, common characteristics or colleagues before taking linguistic skills into consideration. My aim is to achieve the best out of peer pressure and peer assistance.
