Experimental solutions for colleges and universities
Description of the scheme background:
Since 1999, with the expansion of colleges and universities, the proportion of college students has increased, but there has not been a corresponding increase in teacher strength and teaching resources. In teaching, there are many problems in experimental teaching:
1. High laboratory construction costs
Traditional experimental teaching mainly relies on expensive experimental equipment, which has large investment in the early stage and high maintenance cost in the late stage. The development process is limited by time, location, manpower, material resources, and financial resources. As a result, experimental teaching cannot be effectively carried out, which seriously affects the quality of teaching.
2. Teacher guidance is difficult to put in place
It is difficult for limited teachers to carefully guide a large number of students in a limited time, and experimental teaching is easy to walk through. Design and inquiry experiments are even more difficult to carry out.
3. Teaching goals are difficult to implement
Cultivating practical ability, design ability and innovation ability is an important goal of experimental teaching. However, at present, students mainly conduct verification experiments based on the experimental instruction book. Some experiments are inaccurate, and the operation training is insufficient, and the innovation ability is difficult to improve.
Overall plan of the plan:
In order to solve the problems of experimental teaching in colleges and universities, for the "Linux operating system", "computer network", "basic circuit analysis", "digital circuit and logic design", "analog circuit", "high school" in college and undergraduate education After many years of research, the Beijing University of Posts and Telecommunications has developed a supporting open virtual experimental teaching system based on B / S structure that can be carried out on the Internet. The system simulates the experiments used in real experiments. Equipment and equipment provide an experimental environment similar to real experiments, and provide online experiment management functions. It can easily realize remote experiment teaching and management, and can support multiple users to operate online at the same time.
System users are divided into three roles: teacher, student and administrator, and different roles have different permissions.
Teacher: New experiment, release experiment, layout experiment, experiment result and experiment report correction, etc .;
Students: Must do experiments, choose to do experiments, self-directed experiments, submit experiment reports online, save experiment results, check grades and comments given by teachers, etc .;
Administrator: manage the teaching forum and experiment users, group management and authority management;
Through the analysis of the demand for experimental teaching, the system has designed relevant teaching functions. Including the release of experimental requirements, the recording of experimental results, the submission of experimental reports, the revision of experiments, the achievement statistics, etc. can meet the needs of experimental teaching.
Service provision:
Beijing Runnell Network Technology Co., Ltd. will provide a series of technical support for this solution, including pre-sale and post-sale related services such as installation, training, establishment of supporting resources, system integration, and function customization. Provide a strong guarantee for the successful operation of the program.

Program features:
1. Adopt B / S architecture, open management, students only need a computer with internet access to experiment conditions;
2. Provide a complete set of virtual experiment management system, which can be seamlessly integrated with other teaching and administrative systems;
3. Adopt multimedia technology to provide abundant experimental teaching resources and facilitate students' learning;
4. Provide intelligent guidance for the key points in the experiment, and provide students with one-to-one real-time guidance;
5. Provide automatic correction function of experimental results, reduce the workload of teachers;
6. The virtual experiment teaching system implements the goal of training experimental ability to the course, from the course to each typical experiment, and carefully designs the experiment content;
7. Organically integrate knowledge learning and experimental hands-on training to form a complete experimental teaching system;
8. Virtual instruments can present experimental phenomena that real equipment cannot reflect;
9. Friendly and intuitive interface, all simulation equipment operation is close to the reality, strong sense of reality;
10. Strong scalability, can add experimental equipment and typical experiments flexibly according to teaching needs, and provide personalized customization services;
11. Cross-platform, support Windows, Linux and other operating systems;
12. The smart client provides students with flexible online + offline experiments.
