The evidence STRONGLY supports discussion as a means to teach, practice and assess comprehension, but you have to structure it right and practice it often for it to be a success.  So, here are a few steps from Michael Kamil on how to boost comprehension through extended discussion:

     1.  Carefully prepare for the discussion
     2.  Ask follow-up questions that help provide continuity and extend the discussion
3.  Provide a task or a discussion format that students can follow when they discuss texts together in small groups
4.  Develop and practice the use of specific discussion protocol

How can you incorporate these ideas this week?
