| Outline of Final Research Achievements |
The purpose of this research is to estimate the effect of using high-quality graphics generated with KETpic software through the analysis on the brain wave and brain blood flow of students. As a result, it has turned out that the kinds and progress of students' reasoning process can be detected mainly by tracing the brain activation mechanism through NIRS measurement. Based on this knowledge, we have executed many measurements using NIRS. We obtained important knowledges about the students' brain activities when they understand the shape of graphs of trigonometric functions or surfaces in 3d space. These knowledges are consistent with the result of statistical analysis on the students' outputs in real classroom. Combined with the use of dynamic geometry software, KETpic should become powerful tool to make the effective classroom design possible.
