Preface
Recently, the Ministry of Education issued the "Guidelines for Subject Selection Requirements for Undergraduate Admissions to General Colleges and Universities (General Edition)". The "Guidelines" will be implemented from the first-year high school students admitted in the fall of 2021 in provinces with comprehensive college entrance examination reform, and will apply to current and subsequent students. Provinces that want to launch comprehensive reform of the college entrance examination. Among the 92 subject categories listed in the "Guidelines", 60.87% of the subject categories require chemistry , reaching 56. Most science, engineering, and medical majors require physical chemistry and

Question
Compared with the past, the proportion of chemistry in the elective subjects has increased significantly, and many majors require physics and chemistry to be selected together, which is enough to show that chemistry plays an important role in the entire education system. importance, so what is the discipline of chemistry like? Why is it so important? What impact will it have on our future subject selection and study?
Introduction to the discipline of chemistry
The chemistry major is one of the traditional basic majors , inorganic chemistry , organic chemistry, analytical chemistry, and physical chemistry are the four professional basic courses. In science, chemistry and applied chemistry are two basic majors. In engineering, there is a chemical engineering and technology major. These three majors are closely related, but each has its own characteristics.
To put it simply, chemistry focuses on studying the regularity of material changes; chemical engineering focuses on how to amplify experiments to obtain products; applied chemistry is somewhere in between.
Importance of Chemistry
There is no chemistry. Without modern human civilization, everything around us would be either naturally occurring chemicals or newly synthesized chemicals.
has a catchphrase: "Mathematics is a fire, lighting up the lamp of physics; Physics is a lamp, lighting up the road to chemistry; Chemistry is a road, leading to the pit of biology; Biology is the pit, burying all science students." The importance of chemistry as a basic subject.
lacks relevant knowledge of chemistry, and many other majors cannot be studied, such as machinery, instruments, materials, electronic information, automation, civil engineering, and medicine. Chemistry is the basic subject of these majors. It can be said that Without a solid foundation in chemistry, it is impossible to learn these subjects well, or even not understand them at all. It is even more difficult to apply what you have learned. Many college students report that they did not choose chemistry in high school and have to re-learn chemistry in college.
Furthermore, infrastructure construction is still an important part of our development. Without basic subjects such as Chinese, mathematics, physics, chemistry, and biology and their scientific research results, it is difficult for us to survive or even develop. "新冠" and " " delta " highlights this problem, so now the country vigorously advocates the development of basic disciplines , and has also implemented the "Strong Foundation Plan" to promote the development of basic disciplines.
Employment in Chemistry
The employment scope of chemistry majors is relatively wide.
How to deal with subject selection
Under this general trend, more and more students will choose chemistry. It is worth noting that the final college entrance examination score is not the score of the actual exam, but converted according to the grade assignment system. Fraction.
takes Shandong Province as an example. Its grade range is 100 points-21 points. When converting, the actual scores of all candidates are sorted from high to low. The first place is assigned a final score of 100 points, and the last place is assigned a final score of 21 points. points, and the points in the middle can be obtained by converting them proportionally.
From this point of view, What really determines the current college entrance examination is the ranking of results , rather than the actual test results (of course, results will also play a role. Without good results, how can there be a good ranking).
Therefore, during the period when there are no separate subjects in the first year of high school, what students and parents can really do is to roughly screen out what majors are suitable for the future based on their own preferences and personality abilities, work backwards to determine what subjects they want to choose, and then study hard. , try to get good grades, and then make appropriate adjustments based on your grades and rankings when you actually choose subjects.
