The structure of the test questions changes smoothly and the distinction is obvious.
The structure of 1. is relatively stable, except for a slight change on the basis of last year: the pattern of choosing 2+5+6 for science topics and 1+5+6 for liberal arts topics is relatively stable, and the examination scope meets the requirements of Hunan examination instructions and does not exceed the proposition principle of curriculum standards.
2. The concept of the proposition is stable, and the "double bases" are comprehensively investigated: from the distribution of knowledge points, the coverage of the test questions is very large. In all the knowledge series required by the new curriculum standard, there are basically test questions, and the knowledge, skills and methods examined are impartial, which embodies the characteristics that new questions are not difficult and strange, and has a strong evaluation and guidance effect on mathematics teaching in middle schools.
3. The test content is stable, focusing on the main knowledge of high school mathematics, such as function and derivative, trigonometric function and trigonometric solution, solid geometry, analytic geometry, sequence, statistics, probability, etc.
4. Step-by-step questioning and hierarchical control: the difficulty of the test questions increases in the order of multiple-choice questions, fill-in-the-blank questions and answer questions, and various types of questions are from easy to difficult, step by step. There are also 12 short questions in the six answers of arts and sciences. By asking questions step by step, it is easy before it is difficult, so that candidates of different degrees can get corresponding scores, which not only reflects the humanistic care for candidates, but also has a good degree of differentiation.
5. Highlights: The key knowledge of middle school mathematics knowledge system was examined. For example, the function part of science test questions accounted for about 24 points, trigonometric function 17 points, solid geometry 17 points, analytic geometry 18 points, and the number series returned to answer 22 questions, accounting for 13 points. It involves core knowledge points such as function, ellipse and parabola. Be heavily examined.
Innovation and continuous improvement of test questions
This year's college entrance examination questions pay attention to the understanding of the essence of mathematics, highlight the characteristics of mathematics as a thinking subject, and constantly seek new knowledge combinations, such as 1 1 questions for liberal arts and 12 questions for science. 20 10 The hierarchical design gradient of mathematics problems in college entrance examination is not perfect, and there are more people with scores above 600. There is no difference between good grades and average grades in the college entrance examination. However, in the year of 20 1 1, the design of the examination questions was relatively perfect and reasonable.
Respect the differences between arts and sciences and implement humanistic care.
There are obvious differences in the examination papers of liberal arts and mathematics this year, which are mainly reflected in the following aspects: First, the proportion of the same test questions and "sister questions" is small, the score of the test questions with the same liberal arts and sciences is 37, accounting for 25%, while the "sister questions" are only about 17; Second, there are significant differences in the degree of examination of arts and sciences and the type of thinking. Liberal arts focuses on the organization of calculation, mostly basic knowledge and general methods, while science focuses on the rigor of operation and requires higher abstract thinking on the basis of general methods.
For example, the liberal arts question 18 requires students to complete the form according to the known conditions, which is more practical, while the science question 18 is two short-answer questions, which is more abstract and mathematical.
Solid geometry 19, the perpendicularity and dihedral angle of line and plane are found in liberal arts, and the perpendicularity and dihedral angle of line and plane are found in science.
The difficulty of the 20 th application problem, the application problem of science function and the application problem of liberal arts sequence are obviously different.
2 1 analytic geometry problem, science set two questions in the second question, and liberal arts only set 1 question.
These differences show that the test questions under the new college entrance examination are indeed closely related to the syllabus, and also closely related to the new curriculum education concept, fully respecting the actual situation of mathematics teaching in middle schools. This is very important to establish the confidence of liberal arts students to learn mathematics well, and it is also a kind of thinking improvement for science students, and it is also a kind of humanistic care for students of different disciplines.
