Abstract
The problem-solving abilities fostered in sixth grade pupils includes the “ability to reason”, in the elementary school course of study “science” revised in 2008. The curriculum writers devised learning sheets that could raise pupils’ “ability to reason” through “manabiai”, or “mutual learning.”
We established the “Comments Box” in the learning sheets, from which children in the same group can take note of each others’ opinions and advice. In addition, we inspected the effects of the utilization of the “Comments Box” on the students’ developing “Ability to Reason” in class practice.
From the results of the study, it was found that the “Comments Box” provided a good opportunity for the pupils to share and mutually learn from each other’s opinions, and this interchange was indeed effective in promoting their “ability to reason”.
