Freudenthal数学教育論における活動観 : 「再発明」原理に基づく「数学化」と「組織化」に着目して

抄録

The purpose of this study is to clarify the notion of "mathematizing" by Freudenthal. Freudenthal characterizes "mathematizing" by an activity as "organization". "Mathematizing" has not been enough interpreted from a viewpoint called as such an "organization" until now. Therefore, in this study, I define the notion of "mathematizing" based on the "re-invention" in the theory of mathematics education by Freudenthal. And I complement the notion of "mathematizing" by interpreting a meaning of "organization". In conclusion, "mathematizing" is an activity as act out a structure by working on reflective acting to organize experience.
