Mathematics Education in China by the exam-oriented education as a long-term impact of classroom teachers "heavy indoctrination lectures, light Inquiry Teaching"; weight limited knowledge of the "Society", light infinite knowledge, "to learn", teachers used to let through a lot of practice learning mathematics, which is the basic characteristics of mathematics teaching in C In fact teachers should not only allow students to concepts, conclusions and memory skills, imitation and acceptance, more importantly, by teaching the students develop independent thinking, to find the problem, self-explorations, and other appropriate reflection Therefore, the teaching methods of improvement and innovation, not only to the specific teaching methods strategiのs, should also include whether the teaching of leading, motivating, and other basic So, how to improve teaching methods and innovative teachers are the key to the new curriculum In high school mathematics teaching, function accounted for a large proportion of the content, which is a major focus of teaching high school mathematics and Therefore, the function became high school students learn mathematics and difficult As the function of the contents, and abstract, in teaching, we often encounter when students heard lectures is "to understand", but when answers function exercises are difficult but overall, there was no way the My high school math curriculum standards also to function throughout the entire high school mathematics curriculum as a main line, the new function of the content of the course a lot has changed, the contents of the function using a new Accurately grasp the function of high school mathematics curriculum in the position, requirements, and treatment changes, for the effective implementation of the function of teaching, promoting student understanding of the nature of the function is This article aims to create from the situation, the problem lead Xue, independent inquiry, IT Zheng He the aspects of the function of teaching Xinkechengxia study summed up the real Li Jie Chu Nengrangxuesheng function Sixiang the teaching Key words: convergence of information technology context problem Guidance
