2種類のウェブサイトを活用した金星の見え方を理解するための授業開発―地球視点と宇宙視点の明確化を目指して―

Various teaching materials have been developed to understand how Venus appears. However, there were still some issues to be addressed, such as (1) the lack of the element of “observing celestial bodies” required by the Course of Study, (2) a mixture of the viewpoint from the Earth and the Space in the same teaching materials, and (3) the difficulty of recreating the situation in the classroom. In this study, we attempted to clarify the distinction between the two viewpoints by having students “observe” the Venus on two websites. We then developed a lesson that was intended to make the activity more like “observation” for learners by capturing the position and appearance of celestial bodies in real time on the simulation site. To verify the effectiveness of the developed lesson, we conducted a lesson practice targeting students specializing in science at a national university’s education department. As a result, the average total score of the pre- and post-test questions was significantly higher by 1%, suggesting that the class developed in this study had a certain effect on “understanding the relationship between the orbit of Venus and how it appears”. In particular, it was effective in acquiring the “distance concept”.
