This book mainly uses the second kind, focuses on the teacher and the student's application exchange the use information technology constructs the high school mathematics teaching effective exchange to have several meanings: first, can exchange, mainly refers to the technical level, teachers and students have the ability to use information technology for Mathematical Communication; Second, communication should be effective, mainly referring to the effect of communication should be conducive to the development of students'knowledge and ability to learn mathematics; third, the teaching and learning of high school mathematics. Using information technology to construct effective communication in senior high school mathematics teaching means integrating information technology into every link of senior high school mathematics teaching, making it a tool for teachers'teaching and students'cognition, in particular, it becomes an effective tool and platform for multi-dimensional communication and interaction between teachers and students.
