"Primary articulation" is a very important process in the whole learning stage, because the knowledge of the primary school stage is relatively superficial, and good results can be achieved through very simple rote memorization, writing and reading. But junior high school is different, the knowledge content is becoming more and more complex, requiring a certain learning talent or acquired learning ability, in order to ensure the level of grades above the middle and upper levels.
Ordinary middle school students in our province should learn and train mathematics, Chinese classes, English, historical time, political science, physical geography, physics, biology, sports culture, arts and crafts, songs and crafts a total of 11 subjects, although some subjects are not subjects, just shape self-learning ability, but the test results of many subjects can see whether students are smart.
In the case of similar test scores, I firmly believe that most people want their children to be the second kind, after all, high learning effect is a difficult fact, although practice makes perfect, but no one wants to reject a smart mind, so in the middle school link, what kind of child is smarter? A third-grade director who has been teaching for many years put it bluntly: Students in the following three subjects must be smart.
The results of these 3 subjects in junior high school can see the level of students' "IQ"
Except for the three main courses that are on a 120-point scale, the other programs are all 100-point scale. Even 120 points are excellent test scores above 90 points, so people get 90 points as a norm, and middle school students who score more than 90 points in the following three subjects indicate that their intelligence is relatively high.
Section 1: Physics
Learning high-quality mathematics is the foundation for further learning and training physics, but even so, many students may fall in front of physics, and since physics is closely related to practice, they will no longer be as simple as mathematics to master and calculate. Physics, as a necessary subject from middle school to high school, makes many students feel pain. As a result, many students choose the literature and history of ordinary high schools to escape the paws of physics. Even after the reform of the gaokao system, they will try to bypass physics. There are also some regional physics questions that have part of the experiment, in other words, it reduces the investigation of operational ability, so learning high-quality physics does have to have a strong brain shell as a support point.
Although historical time is such a course, traditionally it is a primary and secondary course and is usually not highly valued.
However, I have to say that students who score well on the historical time test and students who can remember the fragments of historical knowledge still have two soft brushes in the eyes of students.
Judging from the characteristics of historical time, it belongs to the scope of past and present literature and history.
In order to learn this course well, students must master various knowledge points, which means that middle school students must have a certain induction ability to penetrate into the various main tasks of historical time and remember many knowledge points.
Obviously, in all the middle school sessions, most students who can deeply understand the historical time and talk about historical stories are very smart, whether it is the ability to summarize work or the ability to remember.
Subject 3: Mathematics
Mathematics is one of the three main courses. From an early age, we need to learn and train mathematics. Although liberal arts students and science students need to learn and train mathematics after high school division, mathematics is indeed a pure science course and must have a certain logic of thinking. In particular, secondary school mathematics is completely different from primary and secondary schools. If you want to understand formula calculations and understand the inferences drawn from an example, it applies to the type of problem, so your math test score above 90 in the first question of the first question shows that you are somewhat smart.
So how to let children learn mathematics well?
Take the words of the world-famous physicist Yang Zhenning: If you want your child to learn mathematics well, the first step is to first clarify the basic concepts of mathematics;
The second is the origin of its basic concept, which requires parents to accompany their children to read more mathematical books and play some mathematical games in the process of tutoring their children's math problems.
However, climbing the pinnacle of mathematics is not an easy task. Yang Zhenning, a world-famous physicist, said: "I also think mathematics is very boring, but when I saw Liu Xuanyu's math book, I was very surprised. Can you still learn math like this? ”
Yang Zhenning was the greatest physicist after Newton and Einstein. The math teacher he can recognize, Liu Xuanyu, can't be wrong.
Who is Liu Xuanyu?
Mr. Liu Xuanyu has studied mathematics all his life, is a pioneer of mathematical science popularization, and has made great achievements in the field of education, writing many excellent works to introduce young people into the sacred temple of mathematics. His three most famous books are this set of "Three Books of Mathematics for Children", including "Mr. Ma on Arithmetic", "Mathematical Fun", "Mathematics Garden", suitable for primary and secondary school students in the fifth and sixth grades to read, and it is also an excellent teaching assistant for parents who want to tutor their children's mathematics, as well as school math teachers.
"Mr. Ma on Arithmetic"
In this book, Mr. Liu Xuanyu uses the tone of "Mr. Ma" to solve arithmetic problems with diagrams, and collects nearly 100 mathematical problems for demonstration, guiding children to explore the relationship and change between the problems. Children are naturally more sensitive to graphs, so graph arithmetic is easier for kids to accept and is more intuitive and easy to understand.
Illustration, which communicates algebra and geometry, becomes the backbone of analytic arithmetic. So if you start with arithmetic, make full use of it, I think, not only for other departments in further study of arithmetic, but also for learning science and engineering, and even statistics, etc., it is also beneficial.
《Math Hobby》
This book is even more interesting, in the pen of Mr. Liu Xuanyu, these small stories from life or historical classics are funny, witty and humorous, reading this book, not only to break the previous misunderstanding of mathematics, but also to be surprised to find that the headache of mathematical knowledge has an interesting other side, the original mathematics can be learned in this way.
Of course, we have to marvel at Mr. Liu Xuanyu's professional understanding of mathematical problems, and even more admire his mastery of words, this method of "building bridges and paving the way" allows children to unconsciously enter the wonderful world of mathematics and be fascinated by it.
The Garden of Mathematics
This book can be said to be a popular version of the basic concepts of mathematics, and it is also the best introduction to advanced mathematics.
Mathematical concepts are abstract and difficult to understand, and various principles are obscure and brain-burning, but in Mr. Liu Xuanyu's pen, the advanced mathematical content of functions, continuums, induced functions, differentiation, integrals and aggregates can even make middle school students who have only studied elementary algebra and geometry read and master it effortlessly.
Reading and understanding this book, I believe that middle school mathematics should be out of the question.
In today's advocating the tactics of the sea of problems, children's mathematical learning is also extremely hard, can not experience the fun of challenges, but also can not appreciate the beauty of mathematics, and reading such mathematical classics, not only can trigger children's interest in learning, but also cultivate children's mathematical thinking, and the improvement of grades has become a good thing.
Mr. Liu Xuanyu's set of "Three Books of Mathematics for Children" is undoubtedly the best choice for children's mathematical enlightenment, children in the upper grades of primary school and middle school can read, open this book, a wonderful mathematical world is waiting for you.
