I feel the role of the teacher is to set the stage for the learning to occur. I teach the students how to work together effectively, and serve as a moderator and recorder during the sharing after work has been done. I ask the probing questions that need to be asked at first, and model for the students how to do this so they can question what they are unclear on. I do do some direct instruction, but only as it relates to the discussion, and often it is for individuals or small groups as I see fit. In the beginning, I found it hard not to step in and tell the students how to do the task. Now I know there is value in the struggle, and try to support students only enough to keep from giving up when frustration sets in. This becomes less necessary as the year goes on and the students get more comfortable with the whole process, and know that it is okay to struggle and that we learn from our mistakes and misconceptions.
