Hy there, I totally agree with you. The best way for students to learn another language is to use it. I am still a student and I am preparing a project with chat. I already have a class that would be willing to do the project with me.
My students are in 9th grade. Their first language is German, but they are learning English as their 2nd language. In October we will start a learning session using Chat and we are looking for Chatfriends anywhere with the right timezone. We would like to split both classes up into groups and let them prepare a presentation together. We prefer to correspond by email and via chat and to chat once a week for about four weeks. The goal is for both classes to communicate in English and not in a classroom environment. You will meet an enthusiastic class and teacher. We look forward to hearing from you.
