Where is statistical knowledges in/out of students? -Instruction of understand the necessity and meaning of knowledges-
PresenterFujiwara Daiki (Japan)
In regard to statistical knowledges learned in elementary and junior high school, I think that informal ideas for formal knowledges are hidden in the student’s. If students show informal ideas through problem solving and are aware of them, they can grasp and explain trends in the data by using histograms, representative values, and so on.
In 2008 and 2017 revisions of Course of Study in Japan, it is important to understand the necessity and meaning. Many Japanese teachers can instruct mathematical knowledges and thinking traditionally based on Jugyou-Kenkyu for interactive and deep learning, but have only a little of plan other than given textbooks to bring out hidden ideas in students. In this paper, I suggest some plans for showing informal ideas for informal knowledges.
