Analysis and Suggestion on the Content of Complex Numbers in Senior High School
Curriculum content greatly supports the achievement of curriculum goals,and the selection and or-ganization of curriculum content should be comprehensively determined with an eye to the educational goals of promoting students'knowledge learning and competence development.In the process of revising of 2003 and 2017 versions of the general high school mathematics curriculum standards,there is a relatively obvious contro-versy over the adjustment of the curriculum content in the part of complex numbers,emphasizing the impor-tance of complex numbers in reflecting the expansion of the number system on the one hand,and deleting a large number of complex numbers on the other.In this paper,on the basis of organizing the content of the high school complex number curriculum,we take complex numbers as the root concept,make a preliminary summary of the main contents and analyze the logical relationship between the knowledge according to the knowledge system of the high school stage,construct the hierarchical relationship between the knowledge of the high school complex numbers,further discuss the key concepts of the high school complex numbers and their teach-ing characteristics,design and draw the knowledge structure diagram of high school complex numbers and put forward basic suggestions for the development of the high school complex number curriculum.The study will make basic suggestions for the optimization of the high school complex number program.
