ABSTRACT  Pair and group activities have become a staple in the L2 classroom, but in many cases instructors do not use the techniques appropriately or to maximum effectiveness. This proposal for training pre- and insewice teachers in the use of group work is based on the principles of action research: first it outlines some issues in the design and implementation of these activities and then includes suggestions for the postobsewation remodeling of activities within a task- and content-based framework for language instruction.
