Interaction plays an important role in the language teaching and learning.  Two main kinds of interaction which are widely used in language teaching and learning are inside and outside classroom interactions. The inside-classroom interactions reflect the common way we teach English in Vietnam in general and at HANU in particular. While the latter, the outside classroom interactions, do not seem to receive enough attention from both teachers and students at HANU.  Through our teaching experiences and classroom observations at KCC, the ideas on this issue pave the way to our presentation today: Outside-classroom interactions – their influences on English language learning and the application of these activities in the English teaching reality at HANU.
