「月の満ち欠け」におけるつまずきの要因分析と指導法の検討～中学生の理解を促進させるために～

抄録

The purpose of this research was to investigate the knowledge and skills necessary for lower secondary school students to study “the waxing and waning of the moon” by clarifying the causes of their struggling while studying this topic.

We found that the following information need to be fully emphasized:

1) Comprehension of the moon’s period of revolution and the moon’s rotating direction.

2) Estimation of the time of the observation based on the position of the sun.

3) Rotation of the horizon from the observer’s perspective along with the rotation of the Earth.

Acquiring this knowledge and these skills will promote the students’ comprehension of the waxing and waning of the moon.
