학교 현장에서 수학적 추론에 대한 실태 조사 : 수학적 추론 유형 중심으로 = Investigation of Present State about Mathematical Reasoning in Secondary School : Focused on Types of Mathematical Reasoning

다국어 초록 (Multilingual Abstract)

It tends to be emphasized that mathematics is the important discipline to develop students` mathemaical reasoning abilities such as deduction, induction, analogy, and visual reasoning. This study is aimed for investigating the present state about mathematical reasoning in secondary school. We survey teachers` opinions and analyze the results. The results are analyzed by frequency analysis including percentile, t-test, and MANOVA. Results are the following: 1. Teachers recognized mathematics as knowledge constructed by deduction, induction, analogy and visual reasoning, and evaluated their reasoning abilities high. 2. Teachers indicated the importances of reasoning in curriculum, the necessities and the representations, but there are significant difference in practices comparing to the former importances. 3. To evaluate mathematical reasoning, teachers stated that they needed items and rubric for assessment of reasoning. And at present, they are lacked. 4. The hindrances in teaching mathematical reasoning are the lack of method for appliance to mathematics instruction, the unpreparedness of proposals for evaluation method, and the lack of whole teachers` recognition for the importance of mathematical reasoning.
