The Function Analysis And The Teaching Design Of "Algorithm" In Senior High School

Algorithm is an ancient concept,with the development of computational science,algorithm has become more and more important.The idea of Algorithm has already become a mathematical quality for modern citizens. In many developed countries, Algorithm has become an important part in senior high school teaching.In April 2003, The Mathematics Curriculum Standard of High School began to be carried on in our country, and algorithm has appeared in the text-books of high school mathematics. But the problem of teaching and learning algorithm has still been drawing people's attention. Because Algorithm is comparatively unfamiliar to high school teachers of mathematics, and there is no ready-made experiences for reference , so they meet challenges in all aspects in their teaching.During the research, the author consulted the development of theory of Instructional Design, analysed the content and function of Algorithm and explored the tactics of teaching Algorithm. Based on the teaching practising, the author gives some preliminary teaching design cases and will wait for further consummates in the teaching practice.
