教科書分析により,中等教育気象領域の変遷についての研究を行った。中学校では1977年の学習指導要領改訂以来,内容の削減が行われてきている。例えば 1977年の指導要領改訂の際に太陽放射とエネルギーの記述が,また1998年の指導要領改訂の際に「日本の天気」の記述が削除された。一方,高等学校では,必ずしもそのような変化が起きていないこと,むしろ環境に関する内容の付加が起きていた。これらの研究結果に立脚し,次のことを提案する。Content transition of meteorology was assessed through review of the text-books utilized by middle schools and high schools in Japan. The meteorological component of these text-books was reduced significantly in 1977, during a revision of the course of study. For example, in middle school text-books, terms of solar radiation and energy were deleted in 1977 and discussion of the Japanese weather system was deleted in 1988. In High Schools text-books, contents have showed an increase because of addition of contents about environment. Based on our analysis, the following curriculum changes are proposed: 1) a new obligatory General Science component should be introduced to the high school curriculum; and 2) teaching about the Japanese weather system should be reintroduced into the middle school curriculum.
