#tejas4ed yes did that a long ago, me and my colleague we use to teach the same language. we use to support each other,find out the areas were we can improve, comment in concrete manner and guide each other .Thus helping both to learn happily

#tejas4ed friends i think that,to set different interaction patterns in the classroom,we must see what the content is focusing on,if we require a brain storming we can have a group of 4 participants or more, if the activity is based on work like preparing something a group of2-3

#tejas4ed friends we must also keep in mind that while setting up different interaction patterns, we must see that the group should be like mixed, one should have slow as well as quick learners in good proportion, also the group should have female representatives included.
