Plans of classes of mathematical activities based on skills of making goods

本文的研究目的在于确立“数学活动”的理念，并在此基础上设计学校教育中的数学课堂。由于这个项目是在日本东部发生大地震之后开始的，所以我们将“灾难中的复兴活动”作为主要研究课题之一加入到我们的研究中。在研究过程中，人们发现了一个新的方面，即学校数学活动的要求不仅是学习描述我们周围各种数学现象的技能，而且是在不受过去数据束缚的情况下设计我们的未来。在这个项目的第一年和第二年，我们搭建了一些基础作品，在最后一年，我们将它们整理成学校数学活动的教材。此外，华沙大学（波兰）和我们以及曼德勒大学（缅甸）组织的国际会议也提出了这些建议。

The goal of our research is to establish the idea of "Mathematical Activities" and to design classes of mathematics in the school education, based on it. Since this project started just after a big earthquake struck the east part of Japan,"Revival activities from disasters" was added to our research as one of main subjects. During its research a new aspect was found with its importance and it is that the claim of mathematical activities in schools is not only learning skills todescribe various phenomena around us in mathematics but also designing our future without being tethered to the past data. In the first and second years of this project we built some fundamental works, and in the final year we arranged them as school teaching materials of mathematical activities. Moreover they were presented in the international conferences organized by Warsaw University (Poland) with us as well as by Mandlay University (Myanmer).
