Behind Changan Qiyuan E07 is Unicom’s C2M overall solution innovation

Recently, the world’s first smart variable new car based on the SDA platform, Changan Qiyuan E07, was unveiled at the Changan Automotive Digital Intelligence Factory. This digital intelligence factory focuses on the production of intelligent networked new energy vehicles and is the unveiling unit of the "National Intelligent Manufacturing Pilot Demonstration Factory".

"Black Light Factory" is the most concrete description of advanced intelligent manufacturing production spaces such as Changan Automobile Digital Intelligence Factory. Tens of thousands of intelligent equipment perform their duties in the factory, more than 800 robots are lined up, more than 500 AGVs shuttle between them, and more than 100 fully intelligent AGV islands replace the original fixed floor chain transmission, which greatly reduces manual participation and increases production efficiency by 20%.

The reporter also learned that the Changan Automobile Digital Intelligence Factory has adopted an innovative software automatic packaging and testing process, which has greatly reduced the data filling time and improved the efficiency of cloud-based electrical inspection by nearly 100%. The AI manufacturing database has become the first factory in the industry to generate more than 28T of manufacturing data per year.

The first 100% to the machine station, the first 100% to the station, the first independent controllable and 5G-compatible industrial control Internet of Things… The application of 5G technology in Changan Automotive Digital Intelligence Factory has set a number of industry firsts. "This is due to China Unicom’s Legion innovation model." Zhou Hua, general manager of China Unicom’s 5G Fusion Innovation Center and Automobile Manufacturing Legion, which undertakes the Changan Automotive Digital Intelligence Factory solution, said.

Focusing on the C2M model

Meet personalized market demand

Data standards are not uniform, it is difficult to share and integrate, limiting real-time information transmission and business collaboration, business complexity lacks unified management, business collaborative efficiency is low, and it cannot adapt to new market demands… In recent years, in the face of the new consumption patterns of "customer engagement manufacturing", "user-defined car" and "user experience car building", the lack of interoperability between the original systems of traditional automobile OEMs, inconsistent standards, and difficult data sharing have become increasingly prominent.

In response to this problem, after nearly two years of practice and polishing, China Unicom Automobile Manufacturing Corps has given its own answer. On July 19, the Shanghai World Expo Center officially released the China Unicom Automotive Industry C2M Overall Solution (hereinafter referred to as the "Solution") at the "Innovation Achievement Release and Partner Conference" jointly organized by China Unicom Research Institute and China Unicom Automobile Manufacturing Corps.

C2M stands for "Consumers participate in manufacturing, organize production according to orders, and provide delivery response and delivery control according to orders". The core of the C2M solution is the Qingtian unified industrial control platform, which provides data standards, application standards, and information interaction standards, and integrates basic applications such as planning, execution, logistics, and quality. Develop enhanced applications that are compatible with C2M, such as logistics enhancements such as warehouse management, manufacturing execution enhancements such as order insertion management, and program enhancements such as dynamic sequencing, so as to achieve data sharing, instruction accessibility, and business implementation coordination, and ultimately realize delivery visibility.

It is understood that the program is based on the practice of multiple projects such as Changan Automobile, relying on advanced Internet of Things and data modeling technologies to provide enterprises with fully connected visual management to ensure the transparency of the whole process, so as to improve enterprise management efficiency and decision-making ability, and achieve the purpose of reducing costs and increasing efficiency.

Leverage the advantages of Unicom integration

Supporting C2M solutions

China Unicom’s C2M solution involves multiple levels of progressive change such as 5G network replacement, edge application reconstruction, data empowerment, and platform reconstruction. The Legion innovation model of Unicom’s integrated capability aggregation plays a crucial role in it.

The Automobile Manufacturing Corps is one of the first vertical innovation units established by China Unicom for the automobile manufacturing industry. It integrates the group’s technological accumulation and innovation resources, carries out technological innovation for the automobile manufacturing industry, overcomes the technical difficulties in the industry, and practices the responsibility of the central enterprise to serve the national strategy.

The Automobile Manufacturing Corps gives full play to Unicom’s cloud network resources and technological endowments, provides 5G-based "cloud network edge" new infrastructure, and supports "visual, manageable, dimensional, and configurable" platform support. It solves the problems of fragmentation, black box, and inefficiency in the original infrastructure, and meets the industrial production requirements such as data not coming out of the network, uninterrupted business, and unified control plane, providing reliable and credible network protection for C2M.

At the same time, the Automobile Manufacturing Corps provides standardized and process-oriented business modeling around business scenarios, ensuring consistent modeling between different business units, providing business-level API calls for upper-level applications, enabling business connection, service sharing, and capability precipitation. It can quickly track positioning and complete iterations when requirements change, laying the foundation for C2M to quickly respond to business requirements.

Based on the accumulation of China Unicom technology, combined with the characteristics of the automotive industry, the Automobile Manufacturing Corps has created a data management system, providing data collection, storage, analysis, and governance capabilities, integrating global data, breaking down barriers, forming unified sources and unified standards of data and services, and providing high-quality data protection for C2M.

Faced with the "chimney-like" problem in the traditional production and manufacturing process, the Automobile Manufacturing Corps combines industrial control requirements, supports data collection and control command integration by innovatively, and uses its pioneering "factory-workshop-production-station-station" five-level space modeling technology to simplify the architecture, support business two-way forwarding, instructions can go directly to the station and other minimum execution units, and the performance exceeds 30% of congeneric products, providing C2M with the ability to direct instructions.

Promote industrial chain collaboration

Empowering traditional manufacturing to digitally upgrade

The C2M solution not only reshaped the production scene in the factory, but also strengthened the linkage and collaboration outside the factory, promoting the quality of the industrial chain collaboration to a new level.

The solution can not only achieve data sharing and real-time updates with other information systems such as supply chain management systems, but also enable upstream and downstream enterprises in the industrial chain to understand each other’s production status and demand information in real time, break the information island, improve information transparency, form more accurate co-frequency collaboration, and improve the collaborative efficiency of the supply chain.

The C2M solution can also integrate multi-dimensional factors such as market demand, production capacity, material inventory, and material supply planning, and efficiently and reasonably arrange production plans. Under the premise of meeting the order delivery time, it takes into account levelized production, which is not only conducive to the stability of the factory production rhythm, but also conducive to maintaining the stability of the supply chain.

In the face of emergencies, C2M solutions can quickly simulate and analyze, evaluate risks, and this ability to accurately calculate and respond quickly can assist factories in making overall plans, making quick decisions, and minimizing impact. By collecting and analyzing the big data generated by the interaction between the production scheduling system and the supply chain management system, enterprises can continuously optimize the supply chain layout, improve the flexibility and adaptability of the supply chain, and help upstream and downstream enterprises in the industrial chain to better cope with market changes and challenges.

This time, the C2M overall solution released by China Unicom Automobile Manufacturing Corps takes the order as the main line and takes the delivery as the goal, which can quickly realize the delivery response and delivery control, and newly defines the new standard of mixed-line production and flexible production. It will inject new impetus into the digital transformation of traditional industries, which is not only suitable for the construction of new factories, but also for the transformation of old factories.

24 Haval big dogs have arrived at the store, the new front face is more wild, and the through taillights are replaced + stronger 2.0T power.

In the first half of the year, the sales volume of the Haval Dog series broke 70,000, an increase of 58.90% year-on-year! And in order to further enhance the competitiveness, 24 Haval Dogs came into being. Not long ago, the new car has been declared in MIIT. In addition to continuing the style of the hunting version, it also provides a new front face shape, and is upgraded to a through-type tail light, and is equipped with a 2.0T high-power engine. Recently, some netizens have photographed the real car picture of the new Haval Dogs coming to the store, which means that it will be unveiled and listed in the near future. Below, we will find out.

It has to be said that the front face of the new Haval Big Dog is more hardcore. The redesigned air intake grille and headlight area are covered by gun gray trims, forming a through style. The interior is supplemented by double banner trims. The "HAVAL" English logo is integrated with the thicker grille trim, which looks more powerful and wild as a whole. The round headlights and rough front surround are retained, and it still takes the retro + hardcore off-road route. In addition, the new car offers a variety of color schemes such as white, black, gray and orange.

The side of the body has not changed much, the tough lines outline the sense of muscle strength, and it is still equipped with wide wheel eyebrows and roof racks, which continue to emphasize the tough guy style, and the double five-width wheel hub also looks full of hard core. In terms of body size, the length, width and height of the new car are 4620/1890/1780mm respectively, and the wheelbase is 2738mm, which is also consistent with the current model. The rear is mainly equipped with through taillights, which effectively enhances the sense of technology and grade, and continues to be connected with the "HAVAL" English logo, which is very recognizable.

The interior has not yet been exposed, and it is expected to be basically the same as the current model. For reference, the multi-layered center console plus a large number of physical buttons and many independent handles echo the rough appearance style. However, a large number of leather cladding, chrome trim embellishments in the details, and knob-type gear shifting mechanism enhance the sense of luxury. The arched central control screen + full LCD instrument panel + HUD head-up display brings a technological atmosphere, and is equipped with a series of configurations such as vehicle to everything, voice interaction, remote control, intelligent driving assistance, 540 ° panoramic image, wireless charging of mobile phones, ambient lights, electric tailgate and electric adjustment/ventilation/heating seats.

As for the power, according to the previous declaration information, the new Haval Big Dog will be replaced with a 2.0T engine with a model of "GW4N20A", the same as the Haval Second Generation Big Dog, with a maximum power of 175kW (238 horsepower). Compared with the current 2.0T power increase of 20kW (27 horsepower), the transmission system is also expected to match the 9-speed wet dual-clutch gearbox, and the high-end version provides a four-wheel drive system. The power of 1.5T + 7DCT should not be absent, to lower the price of the model. The reference price of the current model is 11.99-16 7,900 yuan. Of course, the specific information will have to wait for the official further release. So, what do you think of the new Haval Big Dog? Please leave a comment.

Wu Mengda personally exposed his physical condition, had been ill and thin, and said ＂it seems to be leaving＂

　　　　　Wu Mengda recently mentioned his illness on a variety show. He admitted that his body has not fully recovered, but he seemed to be in good spirits on the show, and also talked about his state of mind when he was sick: "I feel like I haven’t filmed for a few years, and I feel like I’m getting farther and farther away from many audience friends. When it’s quiet at night, I feel like I’m leaving." It’s poignant.

　　In addition, he also recalled the thrilling moment when filming the movie "Wandering Earth" on the show, because he had to put on a costume weighing 35 kilograms, and he had to hang in the air, which caused him to lack oxygen for a while, "I can’t do it when I come down, so I cry. I really cried that time, it was the first time in my life to film." When the host also asked him if there was still a chance to cooperate with Zhou Xingchi again? Wu Mengda smiled and said, "It’s still the same sentence I said before, I’m not dead yet, he’s not retired yet, there must be a chance." It gave many fans hope.

　　It is reported that 68-year-old Hong Kong star Wu Mengda, who suffered heart failure due to a virus infection in 2014, was once admitted to the intensive care unit. Although he saved his life after resuscitation, he lost more than 10 kilograms after recovering. When shooting a promotional poster for the movie a few days ago, he suddenly felt unwell in his heart, showed a painful expression, and covered his chest with his hands. At one point, he couldn’t even stand still and raised his hand to signal to the staff that he needed help. But after just a few minutes of rest, Uncle Da insisted on filming and kept apologizing to the staff. His dedication was touching. (Sugar Peach/Text)

However, just as she returned to China, she was exposed to a big melon by big fans, which made netizens exclaim.

It is reported that Angelababy has been silent for 48 hours after being troubled by the Crazy Horse Show incident. However, the behavior of public figures watching the strip show not only aroused strong dissatisfaction among netizens, but also eagle-eyed netizens found that the official media also took action to delete Angelababy’s once promotional content. Seeing that the situation had gotten out of control, Angelababy also chose to return home quickly. However, what was unexpected was that Angelababy’s informed fans exposed a big melon after seeing Angelababy: Angelababy will respond to the Crazy Horse Show storm on the 2nd!

The whistleblower revealed that Angelababy will respond on the 2nd, and the incident may be reversed. This news has aroused the curiosity of netizens, who have speculated on how Angelababy will respond to the incident. Many netizens said that they are very much looking forward to Angelababy’s response and want to see how she will explain the incident. Others speculated that Angelababy may respond by holding a press conference. Some netizens even speculated that Angelababy may announce his retirement from the entertainment industry to quell the incident.

However, we can only keep a wait-and-see attitude towards the speculation of netizens. After all, there is no official news confirming how Angelababy will respond to this incident. Moreover, through the revelations of informed fans, we can also see an important signal: Angelababy really likes the entertainment industry and wants to develop well in the entertainment industry!

Angelababy, a Chinese-language film and television actress and fashion model, has made her mark in the entertainment industry since her debut as a model in 2003. She has performed well in movies, TV series, variety shows and other fields, and is deeply loved by audiences. Especially her performance in the reality show "Run, Brother" has won her wide attention and love.

Seres Automotive and China

Recently, I have been paying attention to Smart Selection, and then I have learned about the Jinkang Sailis brand.

I have always felt that Huawei, Kirin and other brands are all from myths such as "," and I feel that this Siris must have some allusions. It’s just that there is no relevant introduction in various channels. It’s a bit mysterious.

I spent a day today getting to know the brand name, and I think I’ve found the answer.

That is: SERES isTo the Eastern Han DynastyThe names of countries and ethnic groups related to silk by geographers and historians are generally believed to refer to China or the surrounding areas of China at that time.

In the past three years, watching the release of SF5 and Sailis, Huawei’s cooperation with Sailis has become smoother and smoother. It is hoped that with the strong injection of the Huawei brand and the lofty vision of the Sailis brand, coupled with excellent products and marketing, Huawei Auto will achieve the stated goal, which is to kill XXX. It’s not impossible, lift up!

Experience in using Xiaomi SU7

Before choosing Xiaomi SU7, I chose Xiaomi SU7 mainly because of its face value and the Xiaomi brand behind Lei Jun.. The appearance of the car is very sporty, especially the electric tail, which is really super cool! After driving for a while, I think the control of the SU7 is excellent, and the intelligent cockpit is particularly convenient.

Main driving experience?
sitting position: The overall sitting posture is low (no seat massage).
field of vision: The seat position is adjusted to the lowest, and the overall angle of view of the hood is very good, so you can easily see the lowest position of the front of the car.
Comfort: I am thin (176cm, 56kg), and the seat wrap is not very strong, but it is not a big problem. In Shenzhen, seat ventilation is just needed, but I seldom use seat massage. I feel that this function is not necessary for me.
NVH performance: I tested it with Apple Watch, and the noise was about 65 decibels (tire pressure 3.0, speed 120).
indisposition When turning, the lateral support reacts slowly, especially in small corners, but the big S corner is ok.

Co-pilot feeling
Summary: There is basically no difference between the seats of the main driver. The main reason is that the seat function is poor, and there are not as many adjustment options as the main driver (no lumbar support adjustment and lateral support). It would be nice if these can be added to the co-driver.
A small problemThe ventilation of the passenger seat will always be on, even if no one is sitting (without turning on the automatic mode), which is quite wasteful. I hope it can be improved through OTA upgrade.

Back row feeling
Summary: My height of 176 is not enough to support my legs, my seat is hard and my backrest is straight. To sum up, it is still poor in the application of family cars, not big sofa seats. For a family car, there is still room for improvement in this part. It doesn’t matter if I drive the coupe personally, and there are very few opportunities to sit in the back row.

Charging performance: There is no problem in reaching 300kw on the 800v platform.

Energy consumption performance: 500 kilometers, energy consumption is 17.7.

Driving experience
Overall evaluation: accurate pointing, hard comfort mode filter, obvious movement adjustment, and road sense transmission in place. The steering is light, the chassis is stable, the low center of gravity provides more driving experience, there are simulated sounds in the sports mode, and the dynamic response is rapid (the tire pressure is 3.0 in the tail position). Track mode has not been experienced yet.

Intelligent cockpit experience
Intelligent driving SR has clear recognition and many models, which can identify the tripod on the ground. Including the action of pedestrians looking back at the car can also be recognized and simulated.

Valet parking
The automatic learning of parking service route can be realized without additional user settings, which reduces the learning time of users. It is very convenient to choose the target parking space and vacant space along the way for parking (Xiaomi’s parking service function supports the creation of a parking lot route with a maximum length of 2km, which is related to the length and has nothing to do with the number of underground parking lots, that is, the route can be supported as long as it is within 2km, no matter how many floors it spans).

NOA
1. NOA in the urban area can’t experience the high-speed NOA yet. It has normal lane-changing and overtaking functions, and can be the first echelon. It is natural to automatically change lanes and overtake at high speed, which is in line with my driving habits. The most obvious perception lies in the exit, and he will judge for himself whether to slow down, overtake or slow down, which is in line with his driving habits.

2. Shortcomings: The automatic parking function is too radical and needs to be adapted. At the same time, there is a possibility that the car butt is facing the post, which needs attention. Now NOA is based on high-precision maps, so when some roads and maps don’t match, NOA will still give priority to maps and make turns. Therefore, opening NOA also needs to keep focused on driving.

Xiao ai tong Xue
Summary: Xiao Ai has a great experience, quick response and comprehensive skills coverage.
1. Xiao Ai can help you operate the functional operation on the car. When you don’t know what you need, just ask Xiao Ai where this setting is and he will open the interface for you and point to this operation button.

2. After the car is interconnected, answer the phone through the mobile phone. After the voice of WeChat, the sound comes from the headrest of the main driver, and it is impossible to use Xiao Ai.

Car machine system
1. The UI of the car is very beautiful and smooth, so I won’t go into details. I don’t understand the purpose of the start button on the car. I can go directly when I get on the car and step on the brakes. I can also go directly when I get off the car and hang the P file. Is there a small partner who understands the use scene of this start button?

2. Xiaomi mobile phone can control the air-conditioned seats and songs in the car on the mobile phone, as shown in the figure.

3. After Xiaomi’s mobile phone is connected with the car (the mobile phone will enter the power-saving mode and the screen will be black), you can wake up the payment code of the mobile phone and sweep it through the car. This is because the toll station and the parking lot reduce the steps of operating the mobile phone. It would be better if you can judge whether to open the payment code and sweep it through the camera outside the car (when the car drives to the toll station, you can open the receipt code by voice, of course, this is based on the fact that you don’t have ETC, or the parking lot doesn’t support ETC payment).

4. Disadvantages: It is connected with Xiaomi’s mobile phone, and it can also "play mobile phone" through the car screen while driving, which has security problems.

Personal deficiency view
1. The rearview mirror without a frame is very beautiful, but instead of adjusting the lens inside the rearview mirror alone, the whole rearview mirror is adjusted together, and there is no rear lateral warning, which sacrifices the convenience of confirming the safe lane change through the rearview mirror. In rainy days, there will indeed be water hanging in the rearview mirror. I will buy some rearview mirror "waterproof film" to try the effect, and I will share it with you later.
2. HUD personally feels a little vague and unclear.

3. When multiple positions are saved in the same driver account, even if the correct driving position is selected, there will be a button that cannot be restored to the driving position next time you get on the bus, and there is also a lack of a button to restore the driving position with one button.
4, start the 360 panorama button is single, only through the camera button at the bottom of the screen.
5. The iOS App can’t view 6 cameras at the same time, and the Xiaomi car App on Xiaomi mobile phone can view 6 cameras at the same time. 6. There is no place to check the temperature outside the car.

summary
I am looking forward to the future use of Xiaomi SU7, and think it is a model with strong potential. From the user’s point of view, although there are some minor problems, the overall experience is very positive. Looking forward to the further improvement brought by future software updates.?

Create a closed loop of STEAM ＂Learning, Research and Innovation＂ activities

Under the guidance of the national "double reduction" policy, the task and mission of science and technology education have become more prominent. In order to enable students to acquire scientific and technological literacy through systematic training, more and more teachers have introduced the concept of STEAM education, hoping that under the influence of interdisciplinary and project system, science and technology education can be more effective. However, the development cycle of STEAM projects is often relatively long, and teachers are prone to fall into the misunderstanding of focusing on knowledge over practice, strengthening discipline integration, lacking evaluation with goals, and focusing on form and sparing connotation when designing STEAM activities. In the final analysis, it is because there is no overall view of STEAM activities. Through the practice of STEAM education, we have found that as long as we open up the closed loop of STEAM education from learning, research, creation, display to reflection, the entire STEAM education will be full of vitality, and students will also improve their scientific literacy in the complete STEAM activities.

Designing a future city that responds to climate change is a very interesting and challenging STEAM project. Students need to analyze the impact of climate change on cities and design innovative and futuristic climate change adaptation and mitigation strategies to ensure the health and safety of future urban residents. By designing the curriculum from the perspective of creating a closed-loop STEAM activity, students will have a better learning experience in the activity, generate advanced knowledge and skills, and gain new experience. The following author uses the case of Daoxianghu School in Haidian District, Beijing to illustrate the STEAM activity.

　　　　learn

　　　　Building a knowledge system for STEAM activities

Unlike traditional classrooms, the STEAM learning system is not unilaterally set by teachers, but jointly generated by teachers and students. Therefore, when designing activities, teachers should fully consider the interdisciplinary nature of STEAM activities, jump out of the knowledge and cognitive limitations of their own subjects, attract teachers from more subject areas to join the activities, and enthusiastically embrace the various novel ideas of students. Therefore, creating a learning community that connects teachers, students, teachers and students, teachers and students, schools, and even schools and experts will maximize the efficiency of STEAM learning.

When designing future urban learning activities, we first combined the interdisciplinary nature of STEAM, contacted teachers in science, technology, art, and other fields, and jointly designed a learning list from the perspective of a learning guide.

At the same time, we also used parental resources to establish contact with architectural design experts outside the school, and organized the architectural knowledge recommended by the experts in the electronic learning platform and updated it at any time to ensure that students can learn relevant knowledge of architecture at any time during the progress of the project.

Of course, this knowledge is not instilled in the students at the beginning of the project, but integrated into the whole process of future urban design and production. In order to allow students to truly become masters of learning, we have consciously preserved the link of student-generated knowledge, opened an online forum for students to discover points of interest in the process of advancing the project, and guided students to self-study. For example, when we were selecting the site of the future city, a student showed a black and white photo of a valley in the Himalayas 100 years ago. Today, 100 years later, when humans come to the same location again, they are surprised to find that the former valley has become a lake. It turns out that in the past 100 years, the temperature of the earth has continued to rise, causing the glaciers in the Himalayas to melt and form a new water source. Inspired by this event, the students were bold and innovative, and quickly thought of whether the Tianshan glacier in Xinjiang would also melt in a few years. If the glacier melts, some former deserts will also become oases. After this novel idea was born, the students thought of the ancient city of Loulan, which is a splendid and mysterious city in history. But the knowledge of Loulan ancient city is poorly understood by both students and teachers. Therefore, while exploring, the students expanded their knowledge of Loulan’s history, culture and other humanities.

　　　　research

　　　　Lay the theoretical foundation for STEAM activities

As another important activity of STEAM, research is of great significance. What we study, how we study it, and what effect we expect to achieve should be deeply considered in the activity design. The famous educator Dewey proposed a five-step method of inquiry teaching, which we combined with STEAM education practice, and gradually formed four main steps of research: setting goals, asking questions, researching materials, and forming reports.

Setting goals: teachers and students have discussed and agreed on goals around a common theme. For example, by analyzing the content of the project and combining our understanding of climate and future cities, we have formulated 4 goals: 1. Our city needs to cope with various extreme climates, such as very hot or very cold; 2. Find specific measures for each city to adapt to climate change or extreme weather; 3. Present the project in the best way within a limited time; 4. Let our design have more Chinese elements.

Ask questions: After the goal is clear, organize students to ask specific questions to facilitate further research. The questions raised by students may be imaginative or very focused. As the guide of learning activities, teachers should help students sort out and categorize the problems, and gradually combine the questions with the research content. We use online learning platforms to collect and organize various questions raised by students, such as: What is climate change? What is the problem of global warming? What problems will climate change bring to cities? What are some cases of cities addressing climate issues? What are the impacts of climate change in the cities we live in? Which infrastructure is vulnerable to climate change? Which groups of people in cities are vulnerable to climate change? In addition to climate change, what other development problems do cities face? What would be the main form of energy in the future? Where was Loulan? How could Loulan be made unique?… These questions were not preset by the teachers, but were constantly generated during the activities.

Research materials: Research materials help to solve problems more efficiently, and citing authoritative materials will make research more convincing. We guide students to use tools such as Baidu Academic and Wanfang Database to search for topics, issues and content that need to be researched, download relevant literature materials, extract valuable content for research, and form their own database. Standing on the shoulders of giants, research can be meaningful and generate their own innovations. The students found some famous climate change response cases by searching the data, such as Copenhagen’s liveable city, London’s green city, Rotterdam’s climate protection city, New York’s resilient city, Singapore’s sustainable development city… At the same time, when the students searched the response measures of various cities, they also found the powerful drainage system of the Forbidden City – Qianlong Spitting Water. Drawing on the wisdom of the ancients, the students introduced this concept into the design of drainage pipes in future cities, so that the designed city has both the resilience of a sponge city and strong Chinese elements in the face of severe rainstorms.

Form a report: The report is an important form of research and a vehicle for testing the quality of the research. The report can be a thesis, a manuscript with pictures and texts, or a vivid video. Considering the professionalism of this research, we asked the students to write a research paper in a collaborative manner, specifying how to plan and design this future Loulan New Town to deal with climate change. After thorough research and consensus, the students have laid a solid theoretical foundation and pointed out the direction for the next action.

　　　　create

　　　　Exercise mobility for STEAM activities

Creation requires students to apply the concept of engineering management and put ideas into practice in combination with the presentation of goals, so as to form works that carry research ideas. Creation is also an important way to move from theory to practice. How to guide students to create scientifically tests the level of teachers’ activity design. Our usual practice is to be driven by project goals and ask students to make physical objects such as models, posters or display boards. In the process of creation, we use project reports as management tools to promote the orderly progress of the project. In the process of promoting future urban design, we use the form of making urban models, which can exercise students’ literacy in science, technology, engineering, art and mathematics in all directions.

Making a model of a city requires students to master various tools, materials, and model-making techniques. In addition to providing students with various tool brackets during the learning process, students will also have various specific problems to analyze and solve in the actual creative process, such as students wanting to build complex terrain, want to make a technology-filled shuttle gate, want to design a rotating device, and so on. These specific problems require everyone to learn, explore, and explore together, and there is no existing plan for everyone to learn from. Therefore, teachers should pay special attention to the creative process and require students to strictly check the innovation, aesthetics, science, and technology of the work. Only through a rigorous creative process can students have a truly meaningful project experience and harvest.

　　　　show

　　　　Verify the level of practice in STEAM activities

Presentation is an important form of sharing and evaluation of STEAM activities. Students present the project works, relevant background materials, project advancement process, ideas, plans, etc. in the form of drama, defense or demonstration. Display activities need to reserve enough time for students to fully prepare.

We mainly used the form of drama, and the students wrote their own scripts. After 100 years, a professor went to Loulan New Town to open a branch school, interacted with tour guides and waiters, and finally realized the city’s futuristic sense and the story of scientific design. The whole drama performance was close to 7 minutes, and the students not only refined the design highlights of the future city, but also fully expressed the ideas and ideas in the project, which played a crucial role in exercising and improving students’ comprehensive literacy and teachers mastering the specific gains of students in the activities.

　　　　reflection

　　　　Sublimate the Knowledge Connotation of STEAM Activities

Demonstration is not the end of STEAM activities. To form a perfect closed loop, there should also be a reflection session. Reflection requires not only students to review and summarize the project, but also teachers to seriously reflect on the development of the entire activity, so that knowledge can be sublimated and students can think and act. Generally, we will strike while the iron is hot after the demonstration session, so that students can form written reflections, which will help to improve the connotation of knowledge.

In short, STEAM activities are carefully designed by teachers and generated by students. There must be a complete design process so that the activities can be carried out smoothly, and there must be independent generation by students to make the projects more creative. When teachers design activities from the perspective of complete closed-loop STEAM activities, students’ learning will become more autonomous and efficient, and most importantly, real learning will happen.
