the research of STS Science, Technology and Society is called STS research for short, which explores and reveals the complex relationship among science, technology and society, and studies the positive and negative effects of science and technology on society. Its purpose is to change the separation of science and technology and the disconnection between science, technology and society, so that science and technology can better benefit mankind. STS education is a new concept of science education that emerged in the reform of science education, and its purpose is to cultivate citizens with scientific quality. It requires facing the public and all; Emphasize understanding the relationship among science, technology and society; Attach importance to the application of science and technology in social production and people's lives; Attaching importance to the value orientation of science requires people to consider social effects when engaging in any scientific discovery and technological invention and creation, and to bear social responsibility for the adverse consequences brought about by the development of science and technology. STS research and STS education began in the 196s and 197s in western developed countries. The rapid development of science and technology has brought about economic development, social prosperity and people's happiness, but major social problems related to the development of science and technology (such as environment, ecology, population, energy, resources, etc.) have also emerged. In order to solve these problems, STS research and STS education came into being. It can be said that STS research and STS education are the needs of social development. China introduced the theory of STS education in the mid-198s, and conducted theoretical and practical research on STS education in universities, middle schools and primary schools. In addition, STS is the abbreviation of Space Transportation System, which is the official name of the space shuttle in the United States. We call it the space shuttle. In fact, it is a huge system, and the space shuttle that people often talk about often only refers to the orbiter in the system, which is what looks like an airplane. Sequence Tagged Sites (STS) STS is a general term for a class of molecular markers that are specifically amplified by PCR with a specific pair of primer sequences. By designing specific primers to bind to specific binding sites in genomic DNA sequences, they can be used to amplify specific regions in the genome and analyze their polymorphism. The biggest advantage of using specific PCR technology is that the information it produces is very reliable, unlike RFLP and RAPD, which have some ambiguity.
