Through continuous exploration and experimentation, human beings gradually understand nature and change nature, leading the development of society. In short, the development of society is the process of continuous experimental research and exploration by human beings. The rapid development of high technology in the modern era has been obtained through experimental research. It can be seen that experimental teaching plays an important role in education.

According to the "Opinions of the Ministry of Education on Further Improving the Equipment Work of Ordinary Primary and Secondary Schools under the New Situation", it is pointed out that experimental teaching and sound and beauty equipment and places should be built according to the standards. Support the exploration of the construction of comprehensive laboratories, special laboratories, subject functional classrooms, educational maker space and other educational environments.

Training comprehensive innovation talents in the laboratory

In the course of promoting curriculum reform, the school integrates new ideas, new resources, new equipment, etc. into traditional teaching, and builds laboratories different from traditional meanings, providing a better learning environment for students to conduct experimental exploration and research. The laboratory creates an innovative educational practice education environment and develops students' inquiry and innovation capabilities. In the experiment, students participate in experimental design, experimental research, use existing experimental materials to explore, and at the same time cultivate problem analysis ability and problem solving ability. In the experiment, the students' subjective initiative will be maximized, quality education will be improved, and students' comprehensive ability will be improved.

The important role of laboratory teaching

Laboratory teaching is an important method to systematically learn knowledge. Through hands-on experiment, students can deepen the understanding and memory of textbook knowledge. Mastering experimental scientific research methods is more important than mastering knowledge itself. Students do a lot of experiments, experience a series of processes such as observation experiments, analysis of experimental phenomena, and summary of experimental results in the experiment, and learn to migrate through the acquired skills, so that students can quickly integrate into society to solve problems.

Problems encountered in laboratory teaching

In the experimental teaching, some experimental materials are not reusable, there will be resource loss, and some knowledge is difficult to observe through experiments, which will have certain influence in teaching. It is possible to intuitively see knowledge through experimental research, such as the law of inertia, which can be explained by distance or small experiments in daily life, so that students can see the knowledge at a glance; also some abstract knowledge or knowledge that is difficult to visually display, students cannot pass nature. Phenomena or understanding of knowledge in experimental operations, such as the composition of the heart, can not visually show a heart in front of the students, only through the picture and other materials to understand and learn. The emergence of virtual subject laboratories solves these problems and uses virtual reality technology to make knowledge more intuitive.

Virtual subject laboratory

The Virtual Science Laboratory of Yunhua Science and Education is based on the resources of the school-based textbooks. It is based on the experimental knowledge of biology, physics and chemistry in secondary schools. It focuses on the deep integration of virtual reality technology and education. It has rich experimental teaching resources and integrated teaching experiments. The teaching environment, teaching equipment and teaching mode are integrated into one, which fully meets the needs of students' individualized learning and development.

Virtual reality technology is applied to experimental teaching, and experiments that are difficult to operate and have certain dangers are presented through virtual reality technology, breaking the space and time constraints of traditional laboratories, providing diverse and rich experimental materials and correct experimental guidance to avoid operations. The risk brought by mistakes saves the loss of experimental materials.

Laboratory construction has always been an important part of the construction of educational equipment in primary and secondary schools. It is particularly important to promote the level of school education and equipment, and to focus on the construction of comprehensive laboratory-based and specialized classrooms. The Virtual Science Laboratory of Yunhua Science and Education is mainly based on exploration and hands-on experience, focusing on cultivating students' practical ability and innovative ability. It is believed that the virtual subject laboratory in the future innovation laboratory construction will play an important role.
