In this paper, the author look at Mathematics Study Group with the aim of developing “cooperative mathematical competency,” defined as mathematical excellence demonstrated through collaboration in a group. The lesson was carried out over two consecutive years: In the first year, 12 junior high school students who knew each other participated; in the second year, seven students of different ages from different junior high schools took part. The participants’ responses to the questionnaires indicate that they had possessed a fixed and absolute image of math and math learning, and that this image was changed into a more flexible and relative one after the lesson.
