The Knowledge And Teaching Research Of Complex Numbers

The complex number in mathematics as an important part of the number system is not only the required course of high school,but also the necessary range of university entrance. But due to the decline of the exam outline about complex number knowledge, the difficulty of examination question is becoming easier and easier, so the plural content gradually becomes a complementary knowledge of high school mathematics and students’understanding of complex number knowledge and its application is also becoming more and more difficult. Therefor, study High School Mathematics in the complex number teaching.This paper mainly talks about the basic knowledge and teaching content of complex number. First, through summarizing the complex number knowledge of high school, the question types of university entrance about the complex number and the mathematics thinking of solving complex number problem to promote the new understanding and attention of teachers and students. Secondly,considering the requirements of new knowledge and according to the characteristics of complex number, each class of teaching strategy is designed in turn. And on the basis of the teaching case about this kind of question in the book called The expansion of the number system and the concept of complex number HPM, and through the analysis of the class by teaching evaluation to help teachers improve their teaching quality better. Finally according to the study of complex number in solving other competition of knowledge and its application in the university’s research, we can provide some reference for the selection of teaching content in high school.
