理科授業実践におけるコンフリクトマップの有用性 : てこの原理に関する誤概念に注目して

AI解説:
自然科学の理解過程において、誤概念の修正と正しい科学的概念の獲得が重要視される。特に、物理学の力学分野においては、子どもたちが多くの誤概念を持つことが知られている。本研究は、大学生におけるてこの原理に関する誤概念に焦点を当て、その誤概念の実態を把握し、誤概念を覆すための教育手法を開発することを目的としている。

In this study, misconceptions about leverage were revealed though the use of a questionnaire for the college students enrolled in the Science Methods class at a university (N=105). The questionnaire includes a question about the balance of a stiff piece of wire hang by string in the middle and bent on one side. Through the analysis of the survey responses, this study identified three types of misconceptions about leverage, namely, a) judgment by the appearance, b) forces other than gravity work, and c) the wire balances when the weight on both sides equal. Based on these findings, a lesson plan was developed using the idea of a conflict map by Tsai. The use of the conflict map helped the researchers to develop a lesson to help students change their misconceptions into correct understanding of the principles of leverage through a step-wise manner. A mock lesson about leverage was implemented to the group of college students who are prospective teachers of science in elementary and middle-school science (N=7). The analysis of the surveys administered before and after the lesson showed that student misconceptions about leverage were changed into correct understanding. Limitations and extensions of the study were further discussed.
