The Research Of Senior Middle School's Content Of "Algorithm" Of Mathematics Textbook In Japan

In 1999 the Japanese Ministry of Education finalized the new "study guide outline" ,which has made a new high school math requirements, which the "algorithm" also put forward a more specific requirements for characteristics of the times .In 2003. Japan fully implemented the "study guide outline" as a standard of a new round of curriculum reform. In 2003, China has also implemented a new round of curriculum reform, and the first time "algorithm" content is incorporated into the material.In this paper, the author studies "algorithm" content of the Japanese high school textbook. The author do research about the characteristics of the text materials, teaching materials and the structural characteristics, the preparation of teaching materials and the specific characteristics of case studies. The following important conclusions:In Japanese high school mathematics textbooks, "algorithm" content has lively style , strong intimacy, focusing on real-life links. Focus on the exercise of "algorithm" applied, with the "guiding framework" to maintain a high consistency. In this analysis, the author gives some simple suggestions about"algorithm" textbook writing.
