| Abstract |
Oxygen is an essential gas for our life and very closely related to our living. The activities for making oxygen gas have been introduced in the elementary science textbook for a long time. Traditionally, we used to introduce the reaction of manganese dioxide and hydrogen peroxide to produce oxygen gas. In this study, I tried to investigate the historical changes of the activities for making oxygen gas and to introduce novel activities in the process of writing new elementary science textbook. For this purpose, I analyzed elementary science textbooks issued during the last 70 years since the establishment of the government of the Republic of Korea and examined some kinds of elementary science textbooks in the United States and Japan that have influenced Korean science education. The results of the study are as follows. First, I could not find significant change in activities for making oxygen gas in elementary science textbooks in spite of the changes in curriculum in Korea. Second, I could find activities similar to those in Korea in elementary science textbooks in Japan, but it was difficult to find relevant contents in US elementary science textbooks. Third, I found some simple and novel activities to get oxygen gas on the web. I will discuss the unnecessity of activities for making oxygen gas in elementary science in the poster presentation. |
