Reasons for the difficulty of mathematics in Shandong college entrance examination;

1, the teaching quality is high and difficult.

Shandong province is rich in educational resources, and the teaching quality has always been relatively high. Therefore, where the education level is relatively high, the difficulty of the examination will naturally increase.

2. The pressure of education makes students pursue high scores.

In Shandong, children's education is under great pressure, and parents and society attach importance to the college entrance examination, which makes students pay more attention to mathematics and pursue higher scores. This also means that it is necessary to increase the difficulty of mathematics examination to meet the needs of students.

3. Mathematics education pays attention to basic knowledge and application ability.

Mathematics education in Shandong pays attention to students' basic knowledge and application ability, and the examination is difficult. Because if we simply examine students' memory ability and simple calculation, it is of little significance to get high marks in this subject.

The scope and content of the exam are comprehensive.

The mathematics scope of the college entrance examination in Shandong is relatively comprehensive, and there are also many contents. This increases the difficulty of the exam and requires students to master more comprehensive knowledge points.

5. School enrollment competition is fierce.

The enrollment competition in higher vocational colleges is relatively fierce, so the admission standards for candidates are more demanding. This forces candidates to prepare for the exam carefully, give full play to their advantages in the exam, and make themselves stand out.

Reflections on the answer of mathematics in college entrance examination;

1, the idea of function and equation

Function thought refers to analyzing and studying the quantitative relationship in mathematics from the viewpoint of movement change, and analyzing, transforming and solving problems by establishing the functional relationship and using the image and nature of the function. The idea of equation starts with the quantitative relationship of the problem, and uses mathematical language to transform the problem into an equation or inequality model to solve the problem.

2. The combination of numbers and shapes.

The object of middle school mathematics research can be divided into two parts, one is number, the other is shape, but there is a connection between number and shape, which is called combination of number and shape or combination of shape and number. Therefore, it is suggested that students draw as many pictures as possible when solving math problems, which will help to understand the meaning of the problems correctly and solve them quickly.

3, special and general ideas

This way of thinking is sometimes particularly effective in solving multiple-choice questions, because when a proposition is established in a general sense, it is bound to be established in its special circumstances. Accordingly, students can directly determine the correct choice in multiple-choice questions. Not only that, it is also useful to explore the problem-solving strategies of subjective questions with this way of thinking.

4, extreme thinking problem solving steps

The general steps of solving problems with extreme thinking are: first, try to conceive a variable related to unknown quantity, and then confirm that the result of this variable through infinite process is unknown quantity; Finally, the function (sequence) is constructed by using the limit calculation rules and the result is obtained, or the limit position of the graph is calculated directly.
