Abstract
理科における探究活動は,学習者が科学的に探究する能力や態度を養う上で重要であるが,その準備における教師の負担が大きく敬遠されがちである。この課題解決に向けて,本研究では,身近かつ簡単に入手できる材料だけで準備できるいくつかの実験教材を開発し,それらを用いた中学校理科の発展的な探究活動を実践した。参加した中学生は,仮説,観察・実験,その結果に基づく結論の導出に至る探究の過程を適切に実行することができた。今回開発した教材や探究活動は,費用対効果に優れ,科学的に探究する能力や態度を養う上で有用であることが明らかとなった。Research activities in science education are useful to enhance learners\u27 scientific inquiry abilities and attitudes. However, many teachers tend to omit such important activities in their classes because of their heavy burden in preparation. To solve this problem, we developed several simple experiments only with daily materials, and practiced advanced research activities for lower secondary students by using the teaching materials. The participants in the activities were able to perform reasonable scientific processes including hypotheses, observations, experiments and conclusions based on the obtained results. We found that the developed teaching materials and research activities are cost-effective and useful for students to improve their scientific inquiry abilities and attitudes
