Outline of Final Research Achievements

This research project explored ways to engage students in collaborative mathematical inquiry with dynamic geometry environments. To this end, this project formulated task design principles for supporting students in this activity, and developed tasks and task sequences following the proposed principles. The project also examined the advantages of the designed tasks and task sequences by implementing task-based interviews and classroom-based interventions in lower secondary schools.

Academic Significance and Societal Importance of the Research Achievements

これまで証明と論駁の活動に関する研究は行われてきたが,その活動を授業の場で実現する方法は十分には明らかにされてこなかった。本研究はこの方法を教材系列の開発に焦点を当てて明らかにしたものであり,この点に学術的意義がある。また,学習指導要領や教育振興基本計画では,ICTの活用による協働型学習の推進が強く求められており,その推進に資する教材系列を開発したことに本研究の社会的意義がある。
