According to China Manned Space Engineering Office , the first lesson of " Tiangong Classroom " is scheduled to start at 15:40 on December 9. Shenzhou 13 crew astronauts Zhai Zhigang , Wang Yaping , and Ye Guangfu will teach space at the space station.
This is the second time that China has placed a three-foot podium in the vast space, and it is also the second time that "space teacher" Wang Yaping has taught primary and secondary school students across the country in space. Looking back on the first " space teaching " eight years ago, Teacher Yaping's cordial explanation seemed to be vivid in his mind.
On the morning of June 20, 2013, "Hello everyone, I am Wang Yaping, this lecture will be taught by me..." The sound of heaven was sent back to the ground classroom from the experimental cabin of Tiangong No. 1, which is more than 300 kilometers away from the ground. Everyone was concentrating and holding their breath, watching the live broadcast of the space teaching of the Shenshen Crew Group without turning around.
space teaching has received a warm response, bringing the people closer to aerospace, and turning students and ordinary people from space spectators to participants, which has epoch-making historical significance. At the same time, with the support of technology, this lecture also "flexibly" demonstrated China's aerospace soft power. Amid the awesomeness of surprise and emotion, people can't help but have curious eyes. How are such exquisite teaching skills, such water-free demonstration experiments, and such perfect interactions in the world achieved? I'm afraid even the staff behind the scenes cannot count all the hard work, twists and turns, touching and dedication.
Full ages and people-oriented
A careful audience may find that in the Tiangong No. 1 experimental cabin, there is a large Chinese knot hanging on the left front cabin of the podium, which not only brings joy but also represents Chinese elements. There is also a detail in the fourth experiment conducted by the astronauts: Teacher Yaping carefully embedded the Chinese knot into the "water film", and the water film is still intact. Indeed, the Chinese knot contains too many feelings and feelings of astronauts. It seems complex but orderly, with thousands of twists and turns but unbreakable, bright colors but extraordinary, and is similar to our management methods and styles.

In November 2012, the China Manned Space Engineering Office took the lead in launching various preparations for the popular science education activity of the Shenzhou 10 mission. According to the overall plan for popular science education activities for the Shenzhou 10 flight mission, the China Astronaut Center organized and implemented the implementation in terms of implementation plan formulation, astronaut training, teaching aid development, flight control work, publicity work, etc. Each work has formulated strict time nodes and implementation plans, and an information statistics table is formulated after the work is completed, and a careful review is conducted.
Physical learning teaching aids
In each work site, the flight control group located in the flight control hall bears great mental pressure. Here are elites from various departments. They are like nodes of the Chinese knot, connecting various special groups, playing an important role in inheritance, turning and turning.
The busiest site is located in the ground classroom of Renmin University High School. It has the most interfaces with TV stations, schools and media, especially the live broadcast site, with more than 300 students, with complex staff and diverse levels. However, considering the smoothness of the work, only two staff members were arranged: one was the general dispatcher and the other was the teacher responsible for on-site command and contact. The two staff members selected were capable, experienced many battles, remained calm in the face of danger, and cooperated with each other tacitly.
The hardest scene is the astronauts and simulated astronauts in the Tiangong-1 experimental cabin. Each class is taught for 45 minutes, plus the previous teaching aid preparation, voice communication and plan demonstration, which is a full two hours. Through the camera, they must be in the best condition at all times, concentrate, and have extremely high physical and mental requirements, but they never complain. Every day at 5 pm is the most solemn moment of their day. All the staff are in their seats to meet, summarize the work of the day, find out the shortcomings, and arrange the next stage of work.Many outsiders think that the meeting at 5 o'clock is the end of their day's work and can take a breath after working hard. In fact, this is often the beginning of their overtime work all night. They need to present the modified script on time at 8 a.m. the next day to ensure that the training of astronauts is not affected at all.
science popularization education activities space teaching is relatively new compared to other trainings, the project is new, the time is tight, and the interface units are many. Many documents need to be reviewed or reviewed by many experts one by one, and the training status cannot be determined in time. Therefore, the training method of "first, trial, and parallel" is adopted during the training process. When other trainings are intensive in the intensive training and task preparation stages, theoretical training is carried out first using the training intervals (nights and weekends). The training was bold when the status was uncertain. The instructor and the astronaut discussed and trained for each demonstration project, providing a basis for effectively determining the final status. Due to the tight time, there is no one-way order from theory to operation and finally joint drills, but theoretical training, operation training, and joint drills are carried out interlaced and improved in parallel, ensuring training efficiency.
Wang Yaping did the experiment
space teaching plan for about 40 minutes, and the first coordinated drill of heaven and earth was 39 minutes. I have never tried it in heaven, why is time so accurate? After sufficient research and discussion, these projects (including backups) are highly feasible, so there are fewer failures and better grasp of time; in the early stage, the two main responsible teachers practiced the script in the office based on their own speech speed. When the script was changed greatly, the drill was carried out again; the instructor used the script time with Wang Yaping many times, allowing Wang Yaping to practice the script time according to his own speech speed, ensuring that the time meets the speaker's speech speed; since the water film and water balloon cannot be simulated on the ground, the instructor used soap bubbles and and other homemade water films, so that the astronauts had a visual and sensational feeling during training, no longer explaining to empty things, promoting the coherence of the process, and having a good grasp of time. After the ground drill, the instructor estimates the difference between heaven and earth based on flight control experience. These points ensure the accuracy of the estimated time and effectively reduce changes in on-orbit training and drills.
Shenzhou 10 astronaut crew conducted tests on the ground
As of May 21, three astronauts had reached the hours specified in the training implementation plan and conducted space teaching assessments in the combination simulator. Relevant experts and teachers formed an assessment expert group to score the astronaut's assessment performance. Astronauts have excellent grades and pass the assessment, they have the ability to perform space teaching.
Space Teaching Exam
Gathering all over the world, and visiting from all directions
On August 14, 2007, American Barbara Morgan gave the first human space teaching on International Space Station . She showed students through videos movement and drinking water. Compared with the space teaching conducted by Barbara Morgan, this space teaching by Chinese astronaut is not only more technologically intensive, but also more difficult, allowing students and audiences across the country to feel the wonderful physical phenomena. Like a space magician, it has a great inspiration for the public.

As early as 2010, China Association for Science and Technology launched the continuous "Opening the Dream of Heavenly Palace - National Youth Manned Space Science Popularization Series". With the continuous advancement of the "three-step" strategy of manned space engineering, in September 2011, before the Tiangong-1 target aircraft was launched, ideas about space teaching had begun to be brewed. At the end of 2011, the China Association for Science and Technology first suggested to the China Manned Space Engineering Office that astronauts will teach science classes to young people in space by astronauts in space using the launch of Shenzhou 9 and Shenzhou 10. Subsequently, this idea was discussed many times and received a positive response from the China Manned Space Office. It was adopted after the rendezvous and docking mission of the Shenzhou 9 spacecraft and the Tiangong-1 target aircraft were successfully completed. In early November of the same year, space teaching activities were officially included in the Tenth Flight Outline.This space teaching activity is co-organized by the China Manned Space Engineering Office, the Ministry of Education and the China Association for Science and Technology. The relevant departments of the three organizers formed a working coordination group to be responsible for the preparation of space teaching activities.
teaching expert group consists of experts in the aerospace field and relevant personnel of the astronaut system, education experts, front-line physics teachers and science popularization experts. Regarding the space teaching plan, the expert group conducted a series of arguments from the end of last year to the beginning of this year. At the two argumentation meetings on December 18 and 27, 2012, some opinions put forward by the expert group were finally determined as the rigid principle of this space teaching.
Expert discussion script
For this space teaching, a member of the teaching expert group said that the topic of "weight loss" is mainly to consider related to the relevant knowledge principles learned in middle school, and also to be safe and reliable, small in size and light in weight. Starting from September last year, the space teaching lesson plan team began to solicit opinions from all parties and determine the experimental plan. Several experiments presented in Tiangong No. 1 were repeatedly considered and carefully selected. "The choice of experiment mainly takes into account four aspects: popular science, visibility, education and implementability. The mechanics principle in the weightless environment and the surface tension of were finally determined.
The teacher and astronauts learned
Since then, astronauts, scientists and educators from different fields have widely participated in it, designing experimental content, preparing lesson plans, and developing teaching aids. Before the Shen Ten Crew Group set off, the astronauts participated in no less than 5 formal teaching drills in the world. More than 20 people came from the manned space office, Renmin University Affiliated High School, 101 Middle School, CCTV, Tsinghua Affiliated High School , 11th School, Beijing Normal University School of Physics, Beibei. Expert leaders from the School of Arts of Normal University, , Xicheng District Teaching and Research Department, Donggaodi Science and Technology Museum, Institute of Mechanics of the Chinese Academy of Sciences, Beijing No. 80 Middle School, , China Space Technology Research Institute and related departments attended the meeting, brainstorming and making suggestions for the writing of scripts.
Zhang Xiaoguang's experiments
This is an unprecedented teaching activity. Its significance lies not only in the height of the podium Wang Yaping stands and the space knowledge gained by our youth, but also in the fact that it conveys my country's unique exploration in aerospace science and technology to the world. So, why choose these 5 experiments?
"Classic, easy to understand, novel, ornamental and differentiated. "Mi Qi, a physics teacher at the Affiliated High School of Beijing Renmin University, believes that these five experiments have these common points.
A teacher who participated in the design of the experiment plan said that these five experiments have been repeatedly selected and discussed, and astronauts also gave trial lectures. During the discussion, the expert group learned about the students' knowledge reserves and issues of interest. Everyone will consider whether the experiment is operable in space, what problems will it bring, and what phenomena will it produce.
Space teaching script is the crystallization of collective wisdom and is also a work of hard work. The space teaching script directly determines the effect of the popular science education activity of the Shen Ten mission. In order to ensure that the script design is scientific and reasonable, the physical concepts involved are correct, and rigorous, interactive, interesting and inspiring, the members of the compilation team fully respect science and experts, and based on extensive solicitation of opinions, they drafted The compilation principle is to carry out script writing, trial lectures, reviews, modifications, reviews, post-evaluation modifications, drills, and post-evaluation modifications, etc. according to the plan.
Nie Haisheng Does experiments
In order for the language in the script to conform to Wang Yaping's language habits and improve the naturalness of teaching, Wang Yaping personally participated in the compilation of the script and modified it word by word. After each leader review, the writing team recognized it. Real discussion and implementation have formed a series of versions. On April 8, 2013, the first version of the teaching script was compiled by the astronauts and the members of the teaching expert group. On April 13, the first review was passed, and 17 people attended the meeting, including astronauts who had performed missions. After that, the astronauts conducted trial lectures and training according to this script. After 12 rounds of discussion and modification, on May 21, the script preparation team consulted relevant experts to form the final version of the teaching script and approved it.In order to ensure that everything is foolproof, space teaching analyzes the problems affecting space teaching in detail from five aspects: astronaut medical problems, teaching aids, flight control abnormalities, ground classroom abnormalities and live broadcast activities, and puts forward corresponding handling plans.
attracted worldwide attention, and the best audio is rumored to
"Facing with the vast universe, we are all students." Before the Shenzhou 10 spacecraft , the meaningful words of female astronaut Wang Yaping have been lingering in people's ears. As China's first "space teacher", on June 20, she stood on the highest podium.
Space teaching has refreshed the inherent model of popular science education and physics teaching, and is intuitive, vivid and inspiring. The space teaching of Chinese astronauts is "a battle", and this mission is comparable to the huge risks they are taking to carry out space docking. After the space teaching, many students said: You can’t be an astronaut and you are willing to be a teacher. Space Class inspired the students' curiosity to explore space. Through this class, they had unforgettable memories of weightlessness and water tension. After seeing astronauts answered many students' questions through live broadcast, they still felt unsatisfied. I feel that many questions have not been answered in the live broadcast, so I collected information and continued to study after I went back. Shi Yi, a member of the space teaching expert group and physics teacher at Beijing 101 Middle School, said: "If you give Wang Yaping's lecture, I will give you 100 points."
Science itself is about seeking knowledge and truth, and seeking knowledge and truth requires motivation. Many great scientists have devoted themselves to science and pursue the truth after they have developed a strong interest in scientific phenomena since childhood. Things that cannot be achieved on the ground by astronauts' single pendulum experiments demonstrated by astronauts will cause students to have many "whys" in their minds, which will attract them to explore the essence behind the magical space phenomenon. Micro-world , the movement laws of the macro-world and the universe are different. Through these, students want to understand the essential laws of interaction between objects under the gravity of the earth at different scales. At the same time, many teachers are also listening to the class, which is also very beneficial to improving the quality of teaching.
The first space teaching is an important symbol of the innovative development of the aerospace popularization industry for young people in my country, an important achievement of the joint and cooperation of science popularization education in China, and it is also a major science popularization practice with the largest coverage of science popularization education activities in my country and the largest participation in the public. In the future, when we truly build our own space laboratory and space station in outer space, we will definitely be able to carry out more and more interesting scientific experiments, which can give children more content science classes, let children perceive science and stimulate their interest in exploring the unknown world.
Flying dream never lose weight
