- 中文摘要: Previous research has suggested that asking "why" questions is important for mathematical problem solving. The purpose of this paper was to analyze students' "why" questions which arose during their problem-solving processes and to provide insights into the nature of such questions. For this purpose, we analyzed the processes of solving two problems by a pair of ninth graders, for which they tackled geometry problems using dynamic geometry software. They asked or were prompted to ask "why" questions several times. The analysis showed that as the students explored the problem situation and deepened their understanding of the situation, they related their "why" questions to the mechanism of the situation and pursued the questions more seriously. This implies that asking genuine "why" questions is supported by the solvers' understanding of the problem situation. This also implies that it is important for students to explore problem situations to some extent before they are capable of asking genuine questions.
