1. The design notes that this is "participating in learning". We should attach great importance to the participation of young people and give full play to their main role. The project names can be designed and displayed around the theme, so that teenagers can discover and learn science and technology in the process of doing it and cultivate their exploration ability and innovative thinking. For example, the design of "bus stop" in transportation: first, let teenagers design the bus stop model in their area according to traffic, population, residents' living habits and cultural characteristics; Then, teenagers introduce their design concepts and station features to visitors in their respective booths at the exhibition. This kind of activity makes participants confident and visitors interested, which is more vivid and more in line with the characteristics of the times than just putting exhibits in glass windows for people to visit. 2. Exhibition of scientific and technological achievements This is "exhibition learning". According to a theme, the scientific and technological achievements implemented by students individually or collectively can be gathered together for centralized display. Exhibits can be divided into exhibition boards and objects, static and dynamic. The exhibits must be the innovative achievements of teenagers after observing their daily lives. Through the exhibition, visitors can not only learn and understand the exhibits, but also operate while thinking and broaden their own ideas. This kind of learning is mainly based on exhibits. 3. Thematic discussion This is "discussion learning". When organizing such youth special discussion activities, we should pay attention to the social pertinence of the discussion content. First of all, we should choose a good topic for discussion. That is to say, students should be organized to investigate and collect materials from different aspects in combination with social hotspots and major issues that people care about, and use their own scientific and technological knowledge to analyze these problems and propose solutions in combination with the development of science and technology today. Secondly, we should embody the following characteristics when organizing special discussions: (1) Emphasize "student-centered". In the whole discussion process, the science and technology instructor should turn from the front to the back, and the students should change from the audience to the actual participants, make their own decisions, discuss freely, and further discover, analyze and study problems through discussion, and then solve problems. Only in this way can we change the practice of verifying the authenticity and scientificity of students' papers in the form of expert judges' defense to students. (2) Adopt "interdisciplinary". When organizing youth discussion, the content of discussion is not only related to the knowledge of a single discipline, but often spans multiple disciplines. Because the investigations and experiments that students engage in before the discussion are all practical problems in life, which include science and technology, technology, society and so on. With the development of science and technology, it is not enough to rely on the scientific knowledge of a single subject to solve these problems in science and technology, technology and society. (3) Organizational forms can be divided into thematic forums (around a theme), undergraduate and interdisciplinary seminars (one main topic and several sub-topics), role-playing (different topics and multiple roles) and so on. 4. Hands-on brain exhibition This is "hands-on learning". It breaks through the previous mode of displaying exhibits as works of art in glass windows, and achieves the purpose of scientific and technological exchange through the interaction between exhibits and visitors. This exhibition makes use of typical phenomena in basic disciplines, allowing students to reveal scientific and technological principles, stimulate scientific and technological interest and enlighten scientific and technological wisdom through hands-on and brain activities. It is a dynamic science and technology communication activity for all young people, and it is also an educational activity in which young people participate. These exhibitions can be produced by professionals, or they can be selected through hands-on and brainy exhibition design and production competitions. Should form a series, such as sound, light, electricity, machinery, communication, automatic control, computer applications, etc. , which also includes categories such as "science toys" and "intelligence combination". When designing an exhibition, we should pay attention to the following links: (1) The design idea and expression form should be distinctive. (2) Pay attention to the combination of basic science and technology with contemporary advanced applied technology. (3) emphasize the combination of science and fun, and embody the characteristics of "happy technology". (4) Pay attention to the wide application of information technology such as computers in exhibitions. 5. Various studios This is "laboratory learning". As the name implies, "studio" is "work-oriented", which emphasizes the "hands-on" of each participant. Because of the change of teachers' teaching methods and students' listening methods, the members of the studio have become working partners with each other, and can work and discuss together, thus improving the various abilities of teenagers in the process of work. This is a way of science and technology education that attaches importance to process education and avoids memorizing conclusions. It can help students understand how scientists seek topics and conduct scientific research, and these processes contain a large number of scientists' creative thinking methods, research methods and scientific spirit. There are several types of studios, such as small technological production, small technological experiments and small technological workshops. It has the following three characteristics: (1) Generally speaking, each studio has a very distinct theme, such as "light bending", "structure" and "the cheapest scientific and technological exhibits". (2) The operation mode is very flexible. For example, after one theme is completed, another theme can be selected, which provides conditions for realizing STS (Science, Technology and Society) educational thought. (3) The application range is very wide, and studios can be set up in various popular science activities. Because there are many kinds of popular science activities, the studios set up in the activities should match the theme, such as the "egg drop" studio and the "model airplane" studio. Teenagers can participate in studio activities. Apart from certain exchanges and discussions, it is more important to have more time to make and experiment by themselves and learn science and technology while doing it. Therefore, all kinds of studios can be regarded as a novel mode of off-campus science and technology education for teenagers and play a unique role in improving their scientific and technological quality. 6. Various scientific and technological activities can design some unique, novel and attractive demonstrations and observe scientific and technological activities according to the determined theme, such as proposition contest, air, car, boat and arrow model performance, high-tech demonstration and "problem solving" contest. To strengthen participation and demonstration. 7. The Science and Technology Book Festival will hold a new book exhibition, a salon for young readers, a meeting between authors and readers, a book review garden and other activities. In addition, it can also make full use of multimedia technology to hold activities such as reading and communication of electronic works. 8. The Science, Education, Film and Television Festival should first make use of the audio-visual means of film and television to break through the fixed mode of "theater" and make full use of the changes in space and time in the form of "window of science and technology", so that the audience can always get science and technology education through this mobile window after China International Import Expo(CIIE). Secondly, in addition to selecting some sources of science and education films that meet the theme, we should also pay attention to collecting some videos designed and produced by young people at home and abroad in scientific and technological activities, and play them to achieve the purpose of publicity, learning and communication.
