This thesis studies the Benxi Steel Complex which was constructed at Penshifu (Benxi), Manchuria by a Japanese zaibatsu group named Okura. It focuses on this Complex's development from its beginning in 1906 to 1945, when it was taken over by China following the Japanese defeat in World War 2. There are a few existing studies on the Complex. But these studies do not offer a good analysis of its overall industrial history. This thesis aims to analyze the Complex's whole history and its development with a reference to its manufacturing structure. The Complex was originally a coal mining company. After Okura Group acquired the mining rights of the Miaoergou's iron ore mine, the Complex became a pig iron maker. Penshifu was an ideal place for steel making, because there were in its vicinity all kind of mines including iron ore, coal and limestone. However, because iron ore is magnetite poor ore, the Complex had to acquire specific manufacturing technologies such as magnetic concentration and low phosphorus pig iron manufacturing. The Complex produced low phosphorus pig iron which the Japanese Navy needed. After the Manchurian Incident, the munitions boom occurred, benefitting the company. The Complex then started to expand its manufacturing facilities. After 1937, the Complex executed "The Manchukuo Industry Five Year Program", and constructed a special steel manufacturing division. However, the complex ran into financial difficulties, and failed in the full-scale production of special steel.

地誌学習においてスケールの概念は重要であるが,教師・生徒ともに意識化することが難しい.本稿では,地誌学習にとっての「主体的・対話的で深い学び」を実現するために,「地理的スケール」を援用した協同学習の方法と効果を明らかにした.協同学習の具体的な方法は,ジグソー法を参考にして,個人をナショナルなスケール,小集団をリージョナルなスケール,学級全体をグローバルなスケールに反映させる学習活動を試みた.その結果,授業で扱う地域が社会的プロセスを通して形成されるようすを実感しながら,地域問題やグローバル・イシューの考察に取り組むことができた.本研究で取り上げた地誌学習は,政治地理的な視点を取り入れており,今後,地誌学習と同様に政治地理学習の発展も求められる.
