How to have a good online class？

The following article comes from Huipu by Liu Kai.

Return to the park.

Tracing back to the source, being clumsy, asking for knowledge and seeking novelty

At the beginning of the new semester, normal teaching order has been restored in most parts of the country, but there are still some areas that can only postpone the start of school or continue to implement online classes because of the epidemic, and some areas have to return to online teaching because of the epidemic after normal resumption of school. Although the society generally regards online classes as an expedient measure in a special period, online teaching has become an inevitable trend in the network age. What should teachers, students and parents do to have a good online class? Based on the research results of "learning" in multi-disciplinary fields, this paper gives some suggestions from several general directions.

Author | Liu Kai (bohai university College of Education Science)

Under the social background of pattern involution, "living a good life" and "studying hard" are more closely tied together. However, the ideal is full, the reality is skinny, and the huge social pressure makes the anxiety of students, parents and teachers accumulate, which is difficult to eliminate. Unfortunately, online teaching during the epidemic intensified this conflict.

Scholars have long warned that many learning methods circulating in the market are often wrong. In fact, the empirical research on learning and memory shows that many learning methods that are regarded as the standard by the public are actually useless. For example, the "10,000-hour law", which is popular all over the world, claims that a novice can become an expert by repeated practice for a long time, but it is not applicable to those subjects that need to be considered. Even some studies have found that reading textbooks repeatedly is usually a waste of effort. There are also many students and parents who are bewitched by extracurricular tutoring institutions or best-selling books, thinking that learning may become a happy thing, so they buy "easy-to-score blind boxes" everywhere, resulting in a waste of money and time and poor results. As everyone knows, all learning that can be transformed into games is shallow learning. Although educational games are good, they have attracted countless heroes to "bend their backs"-so far, deep learning cannot be realized from them.

Intuition or individual experience that has not been scientifically verified is often unreliable, so we need "Learning Sciences", a new interdisciplinary subject that uses scientific methods to explore learning laws. As the saying goes, "teaching and learning learn from each other", the science of learning is not only the "amulet" of effective learning, but also the "compass" of effective teaching.

Large-scale online teaching has established a synchronous live classroom in different places, which has guaranteed the normal teaching progress in a special period. But at the same time, it also brings three main problems:

(1) sacrificing teachers’ on-the-spot control of teaching;

② Increased the marginal cost of real-time communication;

③ It reduces the speed and quality of learning feedback.

In this regard, the existing research results of "Science of Learning" provide some suggestions for teachers, students and parents in online classes.

one

How can teachers "teach" better?

(1) Carefully prepare teaching materials.

Basic principles:

Memory content should be "static" (graphic), and understanding content should be "dynamic" (video);

The content is decomposed into a plurality of interrelated small modules; The presentation of teaching materials is very important.

Video material:

Advocate the use of video materials with subtitles or shot from the first angle;

If clues can be added to the video, it will be of great benefit to students in the middle and late grades;

It is better to split the video according to logic, but the double-speed playback effect is poor.

Graphic materials:

PPT is concise and not fancy, and the whole text is not acceptable;

The presentation of new knowledge points, with no more than 4 pages, should be horizontally arranged with pictures and texts;

Use graphics to express the logical relationship of content;

To create a school atmosphere, courseware should use the school background or Logo uniformly.

(2) Adopt appropriate teaching methods.

Basic principles:

Applying the teaching strategy of "technology promoting learning" can never copy the traditional classroom teaching mode;

Avoid asynchronous online teaching and strive for synchronous teaching.

Effective methods:

PBL, role-playing method, inquiry teaching method and case teaching method are effective, so the classroom should be used with caution or not. Gamification teaching is effective for small class or simple content courses;

The mouse icon on the teacher’s side can be changed to a finger shape with eye-catching color (such as black or red).

Reward and punishment means:

Fully create and make good use of virtual rewards, and at the same time often grasp and strictly control cheating.

(3) Increase effective teaching interaction.

Basic principles:

Engage in meaningful interaction, not for the sake of interaction;

Frequency of interaction is not important, but depth of interaction is important;

Adopt a variety of interactive ways.

For students:

It is advisable to refer to students with "you" instead of "you";

Restrain and reduce meaningless expressions, such as "hmm";

Use more friendly oral expressions to be "vulgar" rather than "rough", such as "old irons, learn";

Combining exaggerated expressions or increasing repetitive guiding gestures when teaching key content can improve students’ attention and deepen their understanding;

For the teaching content that needs in-depth understanding, we should create situations to guide in-depth discussion and ask students to pay attention to and share other people’s views.

For teachers and students:

Encourage group cooperation, increase teacher-student interaction and student-student interaction;

Online classes also need a break, which takes 5 minutes;

In the second half of the course, we should consciously stimulate students’ positive emotions;

Encourage more students with average and poor grades;

Pay attention to students’ mistakes, provide convenient communication channels and give timely feedback.

Group discussion function provided by an online teaching platform Source: Network

(4) present a suitable teacher image

Basic principles: Teachers appearing in real person can slightly improve students’ grades and greatly improve online learning experience and satisfaction.

Being able to appear in the camera: show your upper body (head+hands) and stand on the side in front of PPT, keep your eyes on the camera as much as possible, and use expressions and gestures as guiding clues. Otherwise, there is no need to leave the country.

Can’t leave the country: even if you can’t leave the country in person, it’s better to use my photo as your avatar than to leave it blank or scenery.

two

How can students "learn" better?

(1) Learning equipment

Try to use computers instead of mobile phones for online classes; The bigger the screen, the better. Try to use a computer instead of a mobile phone to study. Electronic paper books are a good thing, and electronic reading should be strongly advocated.

(2) study habits

Pay attention to self-study activities before class and prepare well;

Whether it is correct or not, please actively answer the teacher’s questions in class;

The learning effect of accelerating video playback is very poor. If you have to fast forward, you should not exceed 1.5 times the speed.

We must learn self-management and strictly resist non-learning behavior during class.

(3) cooperation between students and students

In the context of online classes, positive individual cooperation will quickly warm the whole group, regardless of boys and girls;

Peer rejection is more likely to lead to online bullying and anger. Please be more tolerant and considerate to people around you.

Everyone is for me, and I am for everyone. Helping and sharing students is beneficial to the overall improvement of learning effect.

(4) Emotional regulation

Maintaining moderate learning pressure can effectively avoid learning burnout;

Positive emotional state can make online learning have higher maintenance, migration, effort and learning satisfaction;

Willpower can effectively beat boredom and improve the learning effect. Students in online classes must consciously cheer for self-control.

three

How can parents "accompany" better?

Online class companionship is a magic weapon to relieve parents’ anxiety, and it is also a direct inducement to trigger children’s emotional fluctuations;

Improving the quality, not the quantity, of parents’ study companionship and actively improving the way of parent-child academic communication are the right way for online class companionship;

Before urging their children to complete their schoolwork tasks, parents should first set aside a 1-minute "buffer period" to recall whether they would have done better than their children now, and then try to talk to their children with a peaceful mind.

four

How can the Education Commission "manage" it better?

Online teaching has obvious differences between urban and rural areas, and education management departments should pay more attention and resources to township schools;

It is not easy to prepare lessons for online teaching, so it is necessary to reduce the burden on teachers and reduce the apportionment of things unrelated to teaching.

Conclusion

The scientificity and effectiveness of pedagogy have been controversial, and the development of learning science in recent 50 years has pointed out the direction for the scientific way of education. Unfortunately, many front-line workers are deeply immersed in the "artistry" of education, ignoring or resisting the "scientificity" of education, which leads to the waste of teaching time and the inefficiency of teaching effect. Education itself does not exclude art, but it cannot rely solely on art. The above suggestions not only have strong "scientific" operability, but also can be flexibly combined to reflect "artistic" creativity.

All the suggestions in this paper come from the research conclusions of hundreds of papers (including meta-analysis) in 16 periodicals of psychology and educational technology CSSCI in recent ten years, and I would like to thank these scholars for their hard work and dedication.

Huaihua, striding towards a new pole

Hunan Daily reporter Jun Xiao

Huaihua, the "West Gate", is taking advantage of the situation.

This "potential" is "one pole and two belts" and "one center and four Huaihua".

In 2015, the regional development strategy of "one core, three poles, four belts and many points" put forward by the provincial party committee and the provincial government positioned Huaihua as "one pole and two belts", that is, building Huaihua into a new growth pole radiating southwest China and connecting Chengdu-Chongqing urban agglomeration, Shanghai-Kunming high-speed rail economic belt and Zhang Jihuai’s boutique eco-cultural tourism economic belt. According to this orientation, Huaihua has risen from the edge of development to the growth pole.

Go all out to shoulder the heavy responsibility. Peng Guofu, secretary of the Huaihua Municipal Party Committee, said that in order to realize the new mission entrusted by the provincial party committee and the provincial government, the Huaihua Municipal Party Committee and the municipal government have determined the development strategies of "one pole and two belts" and "one center and four Huaihua" (that is, building Huaihua into an ecological center city in the border areas of five provinces, municipalities and autonomous regions, building ecological Huaihua, rule of law Huaihua, smart Huaihua and happy Huaihua), and strive to basically establish Hunan’s new growth pole position by the end of the Thirteenth Five-Year Plan.

In mid-September, the reporter walked through the land of five streams, which was refreshing: Huaihua was trying to get rid of the "old impression" of remoteness and backwardness, open its international vision, summon up its energy and start the "acceleration engine" to rush forward.

New engine, new kinetic energy

Expand the map of the whole province. Huaihua, located in the southwest border, accounts for about 13% of the province’s territory and is the largest city and state in the province.

However, the big city is a small economic city, and the main economic indicators are often ranked at the end of the province. Some people jokingly call Huaihua the "end of the province" in Hunan.

In recent years, after several reflections and explorations, Huaihua has found the reasons for its lack of development, unhappiness and superiority, that is, the industrial development is seriously lagging behind, and the reason for its lagging behind is the lack of innovation vitality.

"Take innovation as the core driving force to catch up with development." Zhao Yingyun, deputy secretary of Huaihua Municipal Party Committee and mayor, said that an empty pocket can’t be inflated. Only by making good use of the "golden key" of innovation and making the industry bigger and stronger can we have the strength to shoulder the responsibility and mission of the new growth pole.

Seeking innovation is seeking the future. Huaihua uses "small finance" to incite "big capital" and gather in scientific and technological innovation. Last year, we integrated 330 million yuan of relevant funds, set up special funds for the development of strategic emerging industries, and mobilized 10 billion yuan of financial capital and social capital to invest in emerging industries. The funding for science, technology and industrial development was less than 10 million yuan in 2014, and it has increased to 363 million yuan this year.

According to the "135" project of industrial development in the province, it is a great deal for Huaihua to implement the three-year multiplication plan of industrial and industrial park development and vigorously promote the deep integration of innovation chain and the entrepreneurial chain.

The brand of Huaihua High-tech Zone was Huaihua Industrial Park more than a year ago, and the driving force behind the brand change was innovation. Through the construction of green industrial new towns in the border areas of five provinces (municipalities and autonomous regions), a number of national and provincial innovation platforms, high-tech enterprises and projects poured in, which changed the stagnant situation of the park economy in one fell swoop. In July last year, Huaihua Industrial Park was successfully transformed into a provincial-level high-tech zone, and it is expected to enter the ranks of the "national team" of high-tech zones this year.

In Huaihua High-tech Zone, the brand of Juntai New Material Technology Co., Ltd. was also changed a year ago. It used to be Juntai Pulp and Paper Co., Ltd., which was once the "leading boss" of Huaihua related industries. Two years after it was put into production, it was like a giant animal caught in a quagmire, and it was struggling. Through the transformation, the production of viscose cellulose for textile has changed from a "muddy beast" to a leading goose in the industry.

In promoting the development of industry and industrial parks, Huaihua takes projects as the starting point, creates something out of nothing, creates something out of nothing, and implements two-wheel drive. Nowadays, in Huaihua, scientific and technological projects and high-end growth industries are being laid out, landed and rose.

Xianghua Electronic Technology Co., Ltd. in Yuanling Industrial Cluster independently developed automatic electronic component production equipment, breaking the international monopoly, and attracted Taiwan Province Qilixin Co., Ltd., the world’s largest passive component manufacturer, to join. The two sides invested 7 billion yuan to jointly develop electronic components, and the annual tax revenue is expected to reach more than 250 million yuan.

Compared with three years ago, the number of national and provincial innovation platforms in Huaihua has increased from 3 to 10, and the number of high-tech enterprises has increased from 11 to 56. In the first half of this year, the added value of high-tech industries was 3.5 billion yuan, a year-on-year increase of 14.7%.

Starting a new engine and cultivating new kinetic energy, Huaihua’s four dominant industries, namely, modern business logistics, eco-cultural tourism, medical health and green food, and 15 industrial parks have developed rapidly, which has reversed the passive situation of declining economic growth rate and low ranking in the province, and the ranking of major economic indicators has moved forward greatly. In the first half of this year, GDP increased by 8.1% year-on-year, ranking first in the province.

New channel, new platform

Entering September, the land of Wuxi is a little unsettled.

The track laying of the Huai-Shao-Heng Railway from Shaoyang to Huaihua began in the south direction, advancing at a speed of 2.5 kilometers every day, and a fast railway passage will be built soon.

Huaihua Xianrenqiao Railway Warehouse (railway port) officially started construction, which can be completed by the end of the year, and the construction of Huaihua three-dimensional port open platform has taken another big step.

Huaihua was known as "the gateway of Yunnan and Guizhou" and "the throat of Chu" in ancient times, and was once a transit point of China’s Maritime Silk Road. However, Huaihua’s open vision today is by no means a simple reply to ancient history.

As a city dragged by the train, Huaihua has a special affection for the railway, but the steps of Huaihua people have not stopped on the rails. They are constantly catching up with the progress of the times with the unique tenacity of mountain people.

The Shanghai-Kunming high-speed railway was opened to traffic, the construction of Huaishaoheng railway was in full swing, and the Huaihua railway transportation network developed from a "big" shape to a "meter" shape.

At the same time, the expressway mileage ranks first in the province; Zhijiang Airport is being rebuilt and expanded to build the second largest airport in the province. In March this year, Huaihua became one of the "national comprehensive transportation hubs".

In recent years, Huaihua aims to build a new highland for the development of open economy in Wulingshan area, constantly opens up new channels for opening to the outside world, actively expands the three-dimensional port opening platform, and strives to build a "bridgehead" for Hunan’s opening to the west.

Before the end of this year, international freight trains from Huaihua to Europe will be opened. Next year, Huaihua will open an international freight channel connecting the ASEAN economic circle. And strive to build the Jingyang-Chenchen Railway, and open up the international trade channels to Vietnam, Myanmar, India and other South Asian subcontinent.

The person in charge of the Port Office of Huaihua Commercial Grain Bureau told the reporter that the infrastructure of the public bonded warehouse in Huaihua Economic Development Zone has been completed, and the warehouse will be closed after the customs acceptance, and the Wulingshan Entry-Exit Commodity Exhibition and Trading Center will be operated simultaneously. In April this year, Changsha Customs Agency in Huaihua officially opened its business. The inland port established by Guangzhou Port Co., Ltd. in Huaihua is under construction, and Huaihua will connect with the "Maritime Silk Road" through rail-sea combined transport.

Open and run with Huaihua. In the first half of this year, 22 enterprises registered with the Customs in Huaihua increased, and the total import and export volume increased by 30.87% year-on-year.

New state, new "ecology"

Although it is near the autumn equinox, there is still a heat wave when the sun shines on the ground. On the construction site of Yiwu Commodity City in China, Huaihua Economic Development Zone, the hanging tower is towering, the excavator raises its long arm, and the earth-moving vehicle shuttles back and forth, showing a scene of full swing.

"Working here, there is always a lot of energy." Chen Xiaoyong, chairman of Huaihua Jiarui Yiwu Commodity City Co., Ltd. said that the project started in July, and the land leveling has been completed, and it has entered the stage of foundation piling. From the secretary of the municipal party Committee to the cadres in the park, the service has pushed the project construction out of the "acceleration".

Chen Xiaoyong told a story to reporters. There was a dead old tree in the project land, which affected the project construction. When Hanson Yang, director of the Economic Development Zone Management Committee, heard the news, he immediately took people to forestry, gardens and other departments to apply for logging procedures. "I didn’t expect that it is so convenient to do things here and the service is so enthusiastic!" Chen Xiaoyong from Hangzhou said with emotion.

To adapt to the new normal, cadres must have a new state. Policy makers in Huaihua believe that the state of cadres in party member is also competitiveness and productivity, which is related to the development of the whole city.

Deepen the comprehensive and strict administration of the party and vigorously create a new political ecology with beautiful scenery. In accordance with the requirements of "accountability for mistakes and inaction, replacement without changing the status", Huaihua issued an interim measure to adjust the current leading cadres, and formulated an industrial development performance appraisal plan. The assessment results are the main basis for the selection and appointment of cadres. Seventy-two department-level cadres were promoted and reused because of their outstanding work performance, and 16 department-level cadres who were not "seriously injured" but were not in the state of work and had poor performance were dismissed or adjusted.

Efforts were made to optimize the environment for merchants, and the style of "declaring war on laziness and boosting the spirit" was continuously rectified, and 593 cases of laziness and laziness were investigated and dealt with.

Strict management of officials and theory of performance have ignited the enthusiasm of cadres and officers to start businesses. They have strived to catch up with each other with the enthusiasm of "one person, ten people, and one hundred people", which has brought good and rapid development.

Entering Xupu Honghua Industrial Park, the barren hills and slopes three years ago have become a thriving park. According to the person in charge of the park, it took only eight months from leveling the land and building a standard factory building to the first enterprise starting production. At present, there are 30 enterprises entering the park. This speed is mainly due to the fact that cadres at all levels command with their figures and speak with their actions.

In the first half of this year, Huaihua’s investment in fixed assets increased by 13.7% year-on-year, ranking first in the province.

Style is image, but also strength. Huaihua is changing, Huaihua people are changing, the mental outlook of party member cadres is getting better and better, the people are getting more and more harmonious, and the pace towards a new pole is getting more and more vigorous.

It’s nice to accompany my father around the city.

Wu Xianghuai, a cadre of Huaihua High-tech Zone

In the early years, my father in the country was more diligent in going to town, and it was my must-do "homework" to accompany him around the city. It is a very pleasant thing for me to be filial to my father.

During the people’s commune, my father worked as a village cadre, and every year he had to go to elm bay, the old Huaihua county for a meeting. In the early 1970s, during the war of the Hunan-Guizhou-Zhiliu Railway Conference, my father was one of the millions of road-building troops. After the completion of the railway, he worked as a sideline here for several years, and he is familiar with "elm bay".

A few years ago, I accompanied my father to visit Huaihua City once, but my father was impressed and didn’t feel anything.

With the growth of age, the 70-year-old father rarely goes to town. Not long ago, he went to town. I tricked him into going to town on the grounds that my daughter missed grandpa. This time, in order to leave a deeper impression on my father, I specially chose several tall landscapes.

"Building such a big high-speed railway station should cost a lot of money, right?" The high-end atmosphere of Huaihua high-speed railway station not only opened his father’s eyes, but also inspired his curiosity.

I told my father that high-speed railway station in Huaihua is a transportation hub with an investment of about 2 billion yuan. Take the high-speed train from Huaihua, it takes one and a half hours to Changsha and Guiyang, and five hours to Shanghai and Shenzhen. Moreover, the current mileage of Huaihua Expressway is 676 kilometers, ranking first in the province.

"The length of the expressway is the first in the province, amazing!" Father sincerely lamented.

Drive up Yingfeng Middle Road overpass. Seeing the endless flow of vehicles under the bridge, my father said humorously, "The overpass is just a car passing under the bridge at the same time!"

"Dad’s right. This is the first overpass in Huaihua, with two-way eight lanes, a deck width of 30 meters and a main span of 157 meters, connecting the exit of Chengdong Expressway. " Let me give you a brief introduction.

"With the first article, there will be the second and third articles!" Father said forward-looking.

Step by step. Along Yingfeng Road, around Jinxi Bridge, across Xiangzhou Bridge and onto Hutian Bridge, I introduced myself like a tour guide.

"In the past five years, Huaihua has successively started the reconstruction of Hutian Bridge, Jinxi Bridge and Xiangzhou Bridge, and the construction of Taipingxi Bridge and Taipingqiao Covered Bridge, the urban road skeleton has been stretched to 90 square kilometers."

"So many bridges which remember? I only know that Huaihua has grown up a lot. " Father said with a smile.

After dinner, accompany my father to have tea and talk about Huaihua’s story. I told my father: "Two days ago, Huaihua was rated as the best livable city for the elderly in China, and the health support policy for the elderly is getting better and better."

"You mean, I will come to Huaihua City to support the elderly in the future?" Father asked.

"I believe you will like this new town more and more. The air and environment here are as good as those in the countryside."

That night, my father and I both slept very late.

[See the micro-knowledge]

The "dead end road" is smooth.

On September 17, Peng Li, an individual industrial and commercial household who runs stationery in Yingfeng Middle Road, Huaihua City, drove to Hexi to purchase goods. It used to take half an hour, but now it takes only more than 10 minutes to get to Hexi Wholesale City. He said with emotion: "The’ Broken Road’ is connected, and now the purchase is very smooth."

In recent years, Huaihua City has paid attention to people’s livelihood from small projects, and concentrated its efforts on fighting tough battles in the urban "broken roads", which have optimized the urban traffic network and eased the difficulties for citizens to travel. (Jun Xiao)

The "old bachelor" lives in a new house as the groom

On September 18th, I walked into the resettlement building of Yinjialing Village, Liangtingao Township, Hecheng District, Huaihua City. The red couplets on Xia Changtie Gate, a 54-year-old villager, are still eye-catching. In the past, Yin Changtie lived in a shed-style house in a ravine and remained a bachelor. After moving to a new house with convenient transportation this year, he married the bride back home.

Huaihua, as one of the main battlefields of ex situ poverty alleviation and relocation in our province, completed the task of ex situ poverty alleviation and relocation of 25,734 people last year. This year, 166 centralized resettlement projects and decentralized resettlement projects in the city have started construction, and more than 58,000 poor people will move to their new homes this year. (Jun Xiao)

Now the village is like a park.

"Now the village is like a park, attracting many people from the city to visit." Recently, Zhou Yuru, a villager from Zhoujiaren Village, Chenyang Town, Chenxi County, told reporters that she had been taking her grandson away for three years. When she returned to the village this year, she found that the garbage piled up like a mountain bag by the stream was gone, and the cement road leading to the door was clean and tidy. Surrounded by green trees in each yard, I really wondered if I had gone to the wrong door.

The change of Zhoujiaren Village stems from the construction of "beautiful countryside Happy Home" in Huaihua City, which focuses on "three transformations and one reform" (purification, greening, Chunhua and rural housing renovation). At present, the city has built more than 500 tourism demonstration villages in beautiful countryside. Since 2015, through the development of rural tourism, more than 150,000 farmers have been employed and nearly 50,000 poor people have been lifted out of poverty. (Jun Xiao)

Let young people enjoy traveling and test drive Bao Junyue.

　　On the day of the test drive, three modified Yues were placed not far from the entrance of the park. The sun is fierce, the body is shining, very delicate and energetic.

　　Almost all passers-by, including takeaway and courier brothers, will stop to look at these cars. The strong freshness and attraction are simply irresistible.

　　Before going public, the new car first caught fire with its unique design, and then brushed a circle of friends with its playful "plug-in" screen Car-watch, which became its most direct label. However, when I actually touched it, I realized more exactly where the biggest attraction of this car is.

　　The sense of contrast was also played very smoothly by Bao Junyue.

　　Although it is also a cute shape that people call at first sight, the towering Yue Yezi does not blindly emphasize the soft and cute Q bomb-the design language officially called "Square box" is unique among a number of new energy cars. The square shape of the front face is horizontal and vertical with rounded corners, which is both tough and cute. It is mainly for both men and women.

　　The front bumper with gun gray metal texture is firmly supported below, and the proportion is coordinated and the center of gravity is stable, creating a sense of strength on the dexterous figure. Coupled with the protruding wheel eyebrows and slightly square color rearview mirrors, there are even some hard-core off-road shadows.

　　Baojun Yueye’s city zebra headlights adopt a "four horizontal and four vertical" layout, much like the four horizontal lights in mahjong. As the only vehicle of its class equipped with automatic headlights, the headlights of the new car have 184 LED bulbs built in, with the low beam irradiation angle > 45, the low beam irradiation distance of 60m and the high beam irradiation distance of 178m, which enhances the recognition and improves the driving safety.

　　The new car adopts a large-area waistline-free body with a blank space on the side of the car body, with a modified area of 5.66 m and a detachable wheel eyebrow under the car body, which is sufficient for the later user modification. At the same time, the exaggerated ground clearance also left a deep impression on people. In terms of size, the length, width and height of the new car are 3381mm*1685mm*1721mm, and the wheelbase is 2110 mm. The ground clearance is 150 mm.

　　Four-leaf clover-shaped two-color wheels, red high-performance calipers, and 195/60/R15 low-rolling resistance energy-saving tires as standard (205/65 R15 large-size AT tires can also be added). Although the new car can’t really go off-road, its posture is eager.

　　Coming to the rear of the car, Bao Junyue also adopted a hard-core jeep style design, with the only refrigerator-style side-opening tailgate at the same level, which can be electrically unlocked 90 horizontally like a refrigerator door. The taillights are wrapped in two red rounded rectangular strips, and the shape of the rear bumper also echoes the front bumper.

　　Of course, the "small schoolbag" Car-watch at the rear of the car also brushed a wave of existence at the test drive site. The optional quip screen contains 20,000 LED light beads with a size of 300x256mm and a display area of 15.3 inches. DIY words, pictures and videos are fine, and young people who are proficient in expression packs can rest assured of the whole work. In addition to socializing and playing, this screen can also play a certain guiding role in driving, such as linkage steering and reminding the rear car.

　　In addition, the new car also comes standard with the roof rack made of aluminum alloy, which is 1.55m long, 1.12m apart and bears 30kg, so as to expand more car scenes.

　　Joybox cockpit is obviously a name corresponding to its appearance. In the interior design, Joybox of Yueyezi focuses on exquisiteness, fun and practicality.

　　Many so-called products for young people will sacrifice some qualities in the process of pursuing the ultimate cost performance: rough workmanship and cheap materials. This will even make other aspects of goodwill greatly discounted.

　　Fortunately, Bao Junyue did not paddle in the interior part that directly fits the various senses of users. From materials to design to workmanship, Yueyezi definitely belongs to the upstream level in the same level.

　　The interior of the new car is not amazing at first glance, but it is quite neat, and the color and layering of each partition are just right. The two color schemes of "self-black" and "monologue" (which have been playing with stalks since the name) are not complicated, and most of those personalized thoughts are hidden in the detail design.

　　In the high-frequency contact area, the new car is covered with 100% soft leather, and the upper and lower parts of the instrument panel and the upper trim panel of the door are covered with a more advanced matte finish.

　　The new car is equipped with a 14-inch gamepad and a playful T-shaped steering wheel. The shape and layout of the multi-function buttons are really full of memories of the game. The 14 control buttons can realize six control functions, including automatic driving, intelligent parking, cruise control, multimedia function, telephone answering and voice control. The inside of the steering wheel adopts baseball stitching technology, and the overall grip is lighter and slimmer.

　　The instrument and central control panel adopt a 10.25-inch dual screen with super-large narrow edge, equipped with KiOS intelligent network connection system, and have practical functions such as changeable 3D virtual voice assistant, remote car control of mobile APP, online music, online navigation and so on.

　　In addition, the center console in the car is the first floating island design in the industry, equipped with diversified hanging rods, which can be DIY hung according to user needs. Two USB charging interfaces are arranged under the pendant pole, so it is convenient to charge the mobile phone on the pendant pole.

　　The gun-gray ripple-shaped air outlet is also very delicate. At the same time, Bao Junyue also comes standard with automatic frequency conversion air conditioning, and according to the interior space and human comfort, the optimal distance between the air outlet and the human body is designed to be 0.7m.

　　The design of the new car seat focuses on comfort, the surface is covered with perforated leather, and the cushion is filled with high-density foam, which makes the ride feel soft, but the wrapping is slightly insufficient.

　　In terms of space, the advantages of square body are fully demonstrated. On the data, the maximum head space of the front and rear rows of the new car is 1011mm and 986mm respectively, the maximum sitting position of the front row is 712mm, and the leg space is 1045 mm.

　　The official description is "no depression, no carsickness, wider vision and safer", and the actual riding experience is also true. After the test driver adjusts the seat according to his body (174cm, 70kg), there is plenty of room in his head and legs, and there is no feeling of being imprisoned in the car at all. There is still a lot of room for the main driving seat even if it is adjusted to the highest head.

　　The situation in the back row is also remarkable. When the front row is in a normal riding state, the knee does not directly push against the front seat, and the head also has excellent performance. Such a back row allows people to ride comfortably and with dignity.

　　The rear seats can be laid down independently by 5/5, and the storage volume can reach 715L after being laid down as a whole. In addition, a storage space of 12L is cleverly designed on the outer tailgate.

　　"High box" is not an official title, but it is appropriate to summarize the driving experience.

　　Let’s look at the parameters first. Bao Junyue is also equipped with a single permanent magnet synchronous motor, with a maximum power of 50kW and a maximum torque of 140N?m, which brings a smooth start, worry-free overtaking and strong speed-up. The top speed is 100km/h, with rear-mounted rear-drive layout, and the front McPherson rear three-link integral bridge independent suspension is standard.

　　As a pure electric car that focuses on daily commuting and play, the power feeling is destined to be less intense. When you step on it, the speed will climb up linearly and slowly. But this does not prevent you from getting high on the road: thanks to the body design and the wide windows on both sides, the driving vision is very high and transparent, and the comfort is good enough for you to enjoy rather than endure this journey.

　　What is more surprising is that although the car body is small and towering, it is stable to drive, and it will not float even if the speed is above 80 km/h. When passing through speed bumps and small gullies, the vibration filtering effect of the suspension is also remarkable, and the body does not feel loose.

　　The new car battery is a 28.1kWh lithium iron phosphate battery, with a comprehensive cruising range of 303km, and supports two modes of fast charging and slow charging. The time for fast charging is 35 minutes, and the time for slow charging is 8.5 hours. This configuration has also greatly expanded the scope of application of Baojun Yueye.

　　In addition, Baojun Yueye’s Zhizun Edition is also equipped with the "Lingxi Intelligent Driving System" jointly built by SAIC-GM and DJI Vehicle, which can start intelligent driving with one button, deal with chaotic lane lines, change lanes with a lever, intelligently adjust the speed of corners, identify and deal with obstacles, cope with short-distance traffic jams, and drive with man and machine. Of course, it is also equipped with intelligent parking assistance functions to meet daily needs.

　　Generally speaking, Bao Junyue is definitely not a car for off-road. Commuting in the city and occasionally relaxing in the suburbs are its main car scenes. Its power, endurance and function are designed to provide a reliable support for young people’s daily travel life.

　　The new energy market is terrible to roll up. Within a few years, almost all market segments have been dug up, and the innovation in design and function is too concentrated, which has caused a certain degree of fatigue and repetition.

　　Therefore, the freshness brought by Bao Junyue this time is even more precious, and it is not easy to find a certain demand accurately in today’s turbulent market. Bao Junyue, indeed, has the potential for young people’s first wave to play BOX.

What will China’s quantum computer debut bring？

　　In the experimental building of Shanghai Research Institute of the University of Science and Technology of China, located in Pudong New Area, Shanghai, hundreds of components seem to grow randomly on a workbench of less than 3 square meters: some are bare and bare, while others are supported by wave plates like magnifying glasses, with different sizes and shapes, and the surrounding frame beams are covered with optical fibers. It’s hard to imagine that this is the main body of China Optical Quantum Computer, which has just come out, and has become a shining star in the scientific and technological circles of China and even the world.

　　On May 3rd, the developer of this computer — — The Institute of Quantum Information and Quantum Science and Technology Innovation of China Academy of Sciences announced here that Academician Pan Jianwei and colleagues Lu Chaoyang and Zhu Xiaobo of China University of Science and Technology, together with Wang Hao Hua Research Group of Zhejiang University, have built this quantum computer based on single photon, which is the first optical quantum computer in the world to surpass the early classical computers.

　　At one time, comments came one after another: "China scientists are once again at the forefront of innovation", "Quantum computer opens a new China speed" and "Quantum computing will completely change the future application prospects of mankind" & HELIP; … Even Pan Jianwei, the focus of this achievement, mentioned in an interview that "quantum computing research is like mushrooms after rain, and it has reached a critical moment of explosive development." So what can this "made in China" quantum computer do and what will it bring us? China Youth Daily Zhongqing Online reporter interviewed relevant experts.

　　Bicycles and airplanes

　　The reason why people are full of expectations for quantum computers is not unrelated to the problems encountered by traditional computers: in recent years, traditional computers have gradually encountered a series of problems such as power consumption bottlenecks and communication bottlenecks, and their performance growth is becoming more and more difficult. The demand for high-performance computing technology to explore new physical principles has emerged.

　　Quantum computer is a key for scientists to try to open infinite possibilities in the future. Theoretically, quantum computers can easily "kill" traditional classic computers: someone once made an analogy. If the speed of traditional computers is bicycles now, the speed of quantum computers is like airplanes.

　　The secret of "second kill" lies in the word "quantum".

　　The so-called quantum refers to the most basic unit of matter, which is inseparable. The well-known microscopic particles such as molecules, atoms, electrons and photons are all manifestations of quantum.

　　Pan Jianwei said that quantum has a characteristic that determines its ultra-fast computing power, and this characteristic is "quantum superposition". This is the fundamental difference between the quantum world and the classical world — — The famous "Schrodinger cat" vividly described this paradox. In the classic world, cats are either alive or dead, but a quantum cat can be in the superposition state of "dead" and "alive".

　　With this "nature" of superposition, quantum computing has the ability of parallelism, that is, synchronous computing can be realized. According to scientists, classical computers can only be "either-or" in binary algorithms: either 0 or 1. But quantum computers have the ability to "coexist".

　　For example, in order to "find" the correct information, the classic computer we commonly use at present needs to list and verify all the possibilities when extracting a problem to be solved, which is equivalent to a person with two hands who can only do one thing at a time; Quantum parallel computing can directly calculate and extract the corresponding information, which is equivalent to a thousand-handed Guanyin with two N hands, and can do what two N hands can do at the same time.

　　How fast the latter is depends on the exponential increase of n.

　　At the press conference on May 3rd, Pan Jianwei and the participants relived the classic story about chessboard wheat — —

　　In ancient India, the king was going to reward the inventor of chess and asked him what he wanted. Pointing to the chessboard in front of him, the inventor said to the king, Please put one grain of wheat in the first cell of the chessboard, two grains in the second cell, and four grains in the third cell, and then each cell will be twice as large as the previous one, and so on. When all the grains in the 64 cells on the chessboard are filled, you will give me a reward.

　　The king thought it was simple at first. Unexpectedly, when people brought bags of wheat to start counting, the king found that even bringing all the wheat from India could not meet the requirements of the prime minister — — If you count two pills a second, it will take hundreds of millions of years to count them all.

　　By the same token, Pan Jianwei said, with the increasing of N, the computing power of quantum computers will increase exponentially, and some large-scale computing problems that classical computers can’t solve will be "solved". He takes factorization of large numbers as an example. It takes 150,000 years for a classical computer to decompose a 300-bit large number, and it takes only one second for a trillion quantum computers to decompose this large number.

　　ideal and reality

　　According to Pan Jianwei’s description, quantum computers are also expected to play a big role in the large-scale computing problems of human society — —

　　In the field of public safety, quantum computing can instantly process 6 billion face pictures in the monitoring database and identify a person’s identity in real time; In the field of public transportation, quantum computing can quickly analyze and predict complex traffic conditions, so as to dispatch integrated transportation systems and avoid road congestion to the greatest extent, and so on.

　　However, these are only the "ideal" prospects for scientists at present, and quantum computers in reality are far from reaching this application level.

　　Even the China Optical Quantum Computer only beat the speed of the early electronic computer, which was 10 to 100 times faster than the first electron tube computer and the first transistor computer in human history, but it was "much slower" than the current smart phones and laptops.

　　In the early 1980s, American physicist Feynman put forward the concept of quantum computer, but after more than 30 years’ efforts, it is difficult for the best quantum computer in the world to complete some "seemingly childish" practical mathematical problems, so that people who are skeptical about it give this statement: Although quantum computing is a revolutionary technology, it always seems out of reach.

　　Now, things seem to have changed. At the beginning of this year, Nature magazine said in an article entitled "2017 will be the year when quantum computers come into reality from the laboratory" that quantum computing has long been considered as a technology that will be realized after 20 years. However, 2017 may be the year when this field changes its impression of "limited to research".

　　This change was confirmed in Shanghai, China on May 3rd, when the world’s first quantum computer surpassed the early classical computers came out.

　　Pan Jianwei said that there is a saying in the scientific community that there are "three steps" in quantum computing research as far as computing power is concerned. The first step is to surpass the computing power of the first electronic computer, the second step is to surpass the computing power of the commercial central processing unit, and the third step is to surpass the computing power of the supercomputer.

　　Now, Pan Jianwei team has finished the first step. He said, "At present, what we have achieved is only the first step, but this small step is an important step."

　　Commenting on this achievement, the reviewer of Nature Photonics said: "This quantum computer developed by scientists in China can be said to be the ENIAC in the field of quantum computing." The latter is the world’s first electron tube computer, which opened up the era of classical algorithmic computers.

　　The milestone significance of China, a quantum computer, can be seen.

　　Catch up and surpass

　　In fact, there are many schemes to realize quantum computing in laboratories all over the world, but the difficulty lies in the "manipulation" of microscopic quantum States. At present, Pan Jianwei’s team is working hard in three promising directions: photon quantum computing, ultracold atomic quantum computing and superconducting quantum computing.

　　The optical quantum computer unveiled on May 3rd is a quantum computing prototype that manipulates five particles, namely five optical qubits. According to quantum theory, the computing power of quantum computer will increase greatly with the increase of the number of particles that can be manipulated.

　　Lu Chaoyang, a professor at China University of Science and Technology, told reporters that the team’s next goal is to realize the manipulation of about 20 optical qubits by the end of this year, and is committed to the design, preparation and testing of 20 superconducting qubit samples.

　　At that time, the computing speed of quantum computer will be close to the best commercial central processing unit — — That is, the "second step" mentioned above, catching up with the speed of the current laptop. Lu Chaoyang said that by 2020, it is hoped that about 50 qubits can be manipulated, and then it is possible to achieve the "third step" breakthrough, that is, to surpass supercomputers.

　　Previously, John Preskill, a physicist at California Institute of Technology, mentioned a word called "quantum hegemony", to the effect that when a quantum computer has 5 to 20 qubits, it can accomplish what a top supercomputer can do, and once it has more than 49 qubits, the ability of a quantum computer will be beyond the reach of a supercomputer.

　　"This is called ‘ Quantum hegemony ’ The task, the motivation for scientists to design this problem at first is to show the ability of quantum computers and compete with classic computers to see who runs fast. " Lu Chaoyang said.

　　Pan Jianwei said that in the next 10 years, it is very likely that the scientific community will be able to manipulate 100 qubits. By then, its computing power may be billions of times faster than the most powerful supercomputer at present.

　　Further prediction, Pan Jianwei said that if more than 1,000 quanta can be achieved in the future, scientists may be able to study how consciousness is generated, and may be able to give birth to unimaginable artificial intelligence.

　　But at that time, ordinary people probably still didn’t need quantum computers. Pan Jianwei said that taking the existing mobile phone terminals as an example, the computing tasks that need to be completed can be sent to the cloud through the cloud computing platform, and the quantum computers in the background can complete them.

　　He also admitted that just as people who invented abacus in ancient times would not think of computers today, it is difficult for him to accurately predict the huge energy of quantum computers in the future, and everything can only be seen.
