Teachers often experience difficulties when trying to integrate classroom language into a lesson. The difficulty often lies in that many second language teachers learned the language themselves after childhood, so are not exposed to authentic classroom language. Those teachers must make a particular effort to seek out what the correct language is in order to create the most authentic experience for the students. Students often encounter difficulties when the form in the target language does not make sense in their mother tongue; students must learn to accept that different languages work in different ways.
