Technical models mainly refer to land, sea, and air models. Technical model activities combine science and competition, hands-on work with mental activity, and are highly popular among young people. Their primary purpose is also to develop and enhance young people’s comprehensive practical innovation skills and high quality. Therefore, at the turn of the century, under the new forms of deepening reforms and vigorously promoting quality education, actively carrying out technical model activities is an effective measure for fully implementing quality education.
1. Broaden horizons and enrich scientific knowledge
The science and technology model activities offer rich knowledge. Take marine models as an example: during the creation and operation of marine models, students can learn why ships float, how they maintain stability, how propellers generate power, how ships move quickly, why the Titanic did not sink immediately after being damaged, and why it could not avoid icebergs... If delved deeper, students will encounter radio remote control transmitters and receivers; they will understand (or master) concepts such as force, density, gravity, pressure, magnetic fields, ship structure, engine design and principles, radio technology, and material selection... There is much knowledge that is not covered in textbooks but is frequently needed in real life. This also inspires students to consider how scientific and technological ideas arise from animals, enabling them to imagine boldly and create science and technology models. Some think of dragonflies and airplanes, while fish shapes lead to thoughts about torpedoes, and they can build simple airplane models. In such science and technology model activities, students engage with and apply various types of knowledge, supplementing textbook knowledge, broadening their horizons, enriching their extracurricular life, and gaining more scientific knowledge.
2. Cultivate logic and thinking abilities
Technology model activities require all participants to adopt a dialectical, holistic, and strictly scientific approach in their thinking methods. “Though small, a sparrow has all its organs.” The small technology models are actually large-scale replicas of real vehicles, ships, and airplanes scaled down to a certain ratio; they form a whole, where changing one part affects the entire system.
A model aircraft that uses the reserve time during a competition must go through two stages: high-speed climb and low-speed gliding. The adjustment during the climb stage primarily involves modifying the ground force line and the angle of attack after the wings are twisted. While the center of gravity position, the installation angles of the wings and tailfin, and the rudder also affect the aircraft’s climb posture, changes in these areas directly impact the performance during the gliding phase. Therefore, comprehensive consideration must be given to the different forces and solutions for these two stages during design and adjustment. Additionally, in the design and production of vehicles, ships, and aircraft models, the selection of material strength, stiffness, and weight is very careful, and one optimal option must be chosen from these three factors. Thus, in technology model activities, young people are required to adopt a dialectical, holistic, and scientific approach; otherwise, even a minor error can degrade or even render a technology model ineffective.
It can be seen that a student’s thinking begins with actions. Students’ thinking characteristics are primarily based on concrete imagery thinking; their thinking cannot be separated from images and actions. In operational activities, students must not only use their eyes and hands, but also use their brains to think and speak. This integrates the external operational process with internal intellectual activities, ensuring their dialectics, integrity, and scientific nature. This effectively promotes their cognitive development.
3. Develop good habits
Technology model activities help develop good personalities in students, cultivate their perseverance and pioneering spirit, as well as their attention to detail and patience, and foster a rigorous scientific approach to work.
1. Scientific time management. Students face homework and various interests, as well as the development of their talents, all requiring certain time and effort. Students must manage their time in a scientific and reasonable manner to maintain order and avoid chaos despite being busy.
2. Finish tasks from start to finish. Nowadays, most students are only children. They fear hardship and lack perseverance in carrying out tasks, often giving up halfway. If they are given activities that require their own effort and thinking, allowing them to find ways to complete a technology model project, their interest will increase. Since they enjoy playing interactive toys, this approach can also help them overcome laziness during the production process and persistently complete their impressive works. Thus, the habit of finishing tasks from start to finish is cultivated in them.
3. Collectivist spirit. Students design together, produce together, compete together, helping each other, comparing with each other, and learning from each other. This fosters the collectivist spirit among students, making them consider others and learning how to interact with them. Only under the conditions of a socialist market economy can they collaborate with others to create a great achievement. The era when people like the Curie couple worked behind closed doors to extract沥青 is over. Now, society needs the cooperation of groups of talents, similar to the Apollo Moon Landing program, to transform the world and create the future.
4. Stimulate students' interest in exploring the field of technology.
A scientist or inventor, who undoubtedly develops a strong interest in the things they love, then explores and studies them further, ultimately achieving significant results in that field. Nowadays, we have students create and assemble technical models to help them understand concepts such as the formation of motion, the generation of buoyancy, and the effects of magnetic fields. This prepares them for future research and exploration in this area, establishes a solid foundation, and also fosters hope for success.
In summary: Actively carrying out science and technology model activities is an effective measure for schools to fully implement quality education, foster the all-round development of students in morality, intelligence, physical fitness, art, and labor, and enhance their overall capabilities as cross-century workers and successors; these activities are also effective in implementing the spirit of the "Several Opinions of the State Council on Strengthening Science Popularization" and the national fitness program, as well as the "Revitalize China through Science and Education" strategy proposed at the 15th National Congress of the Communist Party of China.
