The students appeared to be surprised at the differing information each had on the same topic. Therefore, we stopped and discussed whose knowledge was more important. I wish I could say that they knew the answer the first time (they all chose mine as they felt that was the safe answer). It took several sessions for them to figure out that they all could have the right, or partially right, information; it was different, but still part of the whole.
Next, I had each student count the number of comments they had written in the K column, then write the number above the K column and circle it. I told them we would use this number later. I modeled this by counting only my comments (written in black) on the chart paper. Then we moved on to the W column.
