Posing a Quasi-Society in the Problem Context of Socio-Critical Modeling: 'Quadratic Voting' as Teaching Materials（社会批判的モデリングの問題文脈における疑似社会の設定―「クアドラティックボーティング」の教材化―）

抄録

This study proposes a new problem context using students'daily and societal situations as teaching material for implementing socio-critical modeling in mathematics classes. We reviewed the practice of a thematic approach based on critical mathematics education-a theoretical perspective of socio-critical modeling-and reconsidered the framework of socially open-ended problems that emphasize students'daily and societal situations. Based on our research outcome， we propose a quasi-society， as the problem context. School based extracurricular activities such as election of the student body president can correspond to real-world elections. We see it as a quasi-society. This study critically examines the role of mathematics in addressing problems that are inherent in a quasi-society for effectively teaching socio-critical modeling. We used Taiwan's quadratic voting system as the teaching material.
