Outline of Final Research Achievements |
Based upon case-studies of mathematical inquiry using ICT, which are classified into five kind of types. In the mathematical inquiry about mathematical phenomena using dynamic geometry software(GC), we can get many correct data from observation but there is tje diversity of the interpretation of them and question to work next etc. In the mathematical inquiry about mathematal phenonema using Python, we feel the obstaclus to overcome using some method, for example, improvement of program, using library(SymPy), using other application etc. In the case of mathematical(statistical inquiry) using scraping, we need interpretaion and jedgement using knowledge of non-mathematical field. In the case of mathematical inquiry about natural-scientific phenomena the dynamics of inqury is the process of mathematical modelling, in which we need the process of re-formulation of the question. We developed some lesson plan based these case studies of mathematical inquiry, and did some lesson-studies.

Academic Significance and Societal Importance of the Research Achievements |
GIGAスクール構想の前倒しなどにより,学校でのICT環境は小~高にわたって劇的に変化した。「習得・活用・探究」を考えたとき,特に探究の観点での教材開発や授業設計のノウハウが足りないのが数学教育学での現状である。これまでの蓄積をもとに動的幾何ソフトGCに関わる探究のサイクルを進めていくダイナミズムや実践でのノウハウをまとめ,今後の研究への礎石をつくったことと,自然現象やweb上のリソースを利用した数理的探究のサイクルで登場する,他の要因に関してケーススタディを中心に明らかにしている。
