Compared with the past, the new high school mathematics curriculum standard has changed a lot. The basic idea of formulating this standard is: high school mathematics curriculum should be basic, diverse and selective; It should help students to form a proactive learning style; We should correctly handle the relationship between laying a good foundation and striving for innovation; Improve students' mathematical thinking ability; Return to nature, pay attention to moderate formalization; Cultivate students' awareness of mathematics application; Reflect the humanistic value of mathematics; Pay attention to the integration of information technology and mathematics curriculum content; Establish a reasonable and scientific evaluation mechanism. The course content is divided into compulsory courses and elective courses in mathematics. The requirements of the standard for each part are: the course should focus on the real understanding of mathematics; The course content has added three sections: Mathematical Modeling, Inquiry Project and Mathematical Culture. Curriculum should reflect the promotion of information age to mathematics education; The algorithm should enter middle school; Matrix is formally included in the middle school curriculum; Dealing with solid geometry teaching mainly with vector method; Collection is only used as a language; Sequence can be regarded as a special case of function; Inequality should be re-recognized; Function is the core content of high school mathematics; The key of calculus teaching is accurate positioning; Data processing should emphasize the core of statistical thought and avoid turning data processing into "arithmetic" calculation; The teaching of probability and statistics in middle schools should make students really feel the essential difference between deterministic and stochastic mathematical thinking methods; High school learning equations will encounter simple unreasonable equations, trigonometric equations,
Exponential equation, but not expanded.
