On the one hand, this proposition combines reality, sets up real situations, highlights the application of mathematics, and gives play to educational functions. For example, science mathematics 19, a big statistical topic, examines students' subject literacy of data processing and mathematical operation, and selects materials from the actual situation of social and economic production and life in China with the background of ecological environment construction, which fully embodies the function and guiding role of education.
Another situational test of this proposition, the fourth question of science mathematics, takes Chang 'e-2 satellite as the situation to continue deep space exploration after it has completed its exploration and become China's first artificial planet around the sun, and comprehensively uses basic knowledge such as sequence, function and inequality to examine students' ability to analyze and solve problems.
It also embodies the application value and characteristics of the times of mathematics, not only highlights the development and progress of science and technology in the motherland, but also inspires the belief of young students to contribute to the cause of science and technology.
Second, in line with the principle of "the problem is not biased, and the new question is not difficult", this examination focuses on the backbone and key content, guides teaching according to the standard, and reduces the quantity and improves the quality. For example, many students balk at the 12 and 2 1 final questions in science mathematics. These two questions are actually an in-depth examination of the main knowledge, basic concepts and the idea of classification and discussion.
There is also the content of this analytic geometry, which is 1 1 and 20 questions. The former requires students' drawing ability and the latter requires students' mathematical operation ability, but both of them examine the basic definition of conic curve, focusing on the most basic problems and methods in this part.
The life system of such topics also reminds us that to promote the teaching reform in middle schools, we must strengthen the connection between teaching and examination, and reduce and improve homework and exercises.
On the other hand, this examination strengthened the examination of six major subjects, enhanced the flexibility of thinking, and also reflected the function of selecting test questions.
The ninth question of science mathematics, the maximum volume of four pyramids in a sphere, highlights the students' spatial imagination and ability to analyze and transform problems; Question 10, the discussion on the probability of winning two sets in a chess game requires students' mathematical abstraction and core literacy of mathematical modeling.
The setting of these topics also shows that college entrance examination mathematics pays more and more attention to the examination of thinking quality, requiring students to grasp the essence of problems and pay attention to students' comprehensive quality in complex problems.
The trend of mathematics proposition in college entrance examination;
These examples can illustrate the trend of NMET mathematical proposition: emphasizing the original method of the subject, downplaying the conclusion of special skills, and emphasizing the comprehensive application of general methods.
In the study of high school mathematics, the era of "brushing questions" is gone forever, and the score income of "mechanical brushing questions" in college entrance examination mathematics is gradually decreasing. It also aims to guide us to realize that teachers' "teaching" should follow the teaching rules, students' "learning" is more about internalizing knowledge and methods into their own knowledge structure, and inefficient learning methods will only increase the pressure and burden on teachers and students.
