From "SARS" to "New Crown", what masks do everyone wear? "In the 2003 SARS epidemic, ordinary people still wear cotton gauze masks; this time the new crown epidemic, the Chinese people have used non-woven masks..." On the teaching computer screen, Huang Chen, a teacher at the School of Textiles of Donghua University, told college students, "Non-woven masks have a multi-layer fiber structure compared with cotton gauze masks, better filtration performance and interception performance, and stronger protection against viruses." ”
In the closed management of college campuses, the online "golden lessons" during such a war "epidemic" period are still full of dry goods and full of harvests.
Mr. Xu He of the Department of Environmental Science, School of Environmental Science and Engineering, taught the "Environmental Instrument Analysis" course of the Ministry of Education's ideological and political demonstration course
The largest exporter of non-woven masks
In the professional class of "Nonwoven Cutting-edge Technology and Practice", Teacher Huang Chen shared his anti-epidemic experience as a volunteer in the school, encouraged the students with practical actions, and guided them to face the epidemic positively and optimistically. At the same time, Mr. Huang combined the "anti-epidemic" element of masks and made a case to bring into the classroom to stimulate students' sense of professional identity and pride in economic and technological progress.
Huang Chen said that China is also the world's largest export of non-woven masks, with an average of 100 million to 200 million masks exported a day, further enhancing students' national self-confidence and stimulating the spirit of scientific exploration. ”
China's contribution to the global fight against the epidemic does not stop there. "This scientific research achievement reflects the wisdom of Chinese scientists and has made important contributions to the global fight against the new crown virus and the development of new crown drugs and vaccines." In the chapter "Immunization against Viral Infections" in the course "Introduction to Immunology", Chen Ting, a teacher in the School of Chemistry, Chemical Engineering and Biological Engineering, cited the work of the Chinese team of scientists to analyze the structure of the new crown virus as an example.
From the way virus sanitize to the improvement of autoimmunity, teachers and students make full use of the online platform to conduct group discussions to guide students to form a correct concept of epidemic prevention and develop good epidemic prevention habits. At the same time, group debates were also conducted in conjunction with the hot issues of social ethics that emerged during the epidemic.
Solve the problem of "sewer" epidemic prevention
In view of the current complex and severe situation of the prevention and control of the new crown epidemic, Professor Gao Pin, a teacher of the Shanghai excellent course "Building Water Supply and Drainage Engineering", took the focus of current affairs as the starting point, closely combined with the teaching content of the course, compared and analyzed the SARS virus Hong Kong Taoda Garden Incident in 2003, and taught the importance of building drainage system in "blocking the transmission of viruses through aerosols", and at the same time combined with practical cases and discipline frontiers, deepened students' understanding of teaching content, and stimulated students' interest in learning.
Students take classes online, life is inevitably monotonous, "how to make the curriculum more immersive" is the teachers' most concerned issue. Professor Lu Aijiang of the School of Science combined the data approximation problem in the "Computational Physics" course with the development trend of the current round of epidemic situation, requiring students to understand and apply the concepts and theories of numerical fitting, and collating the case data published by the "Shanghai Release" for students to practice.
The students found that the exponential growth of data shows that the virus spreads very rapidly, and the school must also adhere to the "three-piece set" and "five-piece", and have a deeper understanding of the scientific prevention and control that adheres to dynamic zeroing.
The group purchase "project" is divided into six major departments
"Community group buying can be seen as a project, and the participants in group buying can be seen as the six major departments of the project, including the outreach department (collecting the rigid needs of residents and proposing procurement plans), supplier docking (screening supplier funds, identifying the content of goods and delivery time), operation department (processing group purchase data, generating group purchase orders), communication and publicity department (communicating with property and volunteers on group purchase progress, dynamics, and safety precautions), and finance department (checking order data, payment and bookkeeping), Material Department (organize volunteers to distribute supplies). ”
Wang Xiaofeng, a teacher in the Department of Management Science and Engineering of Xuri School of Business Administration, wrote a case of community emergency organization management under the outbreak of the epidemic from the perspective of engineering projects by collecting community group purchase materials. Teacher Wang told the students that clarifying the responsibilities of these six departments can ensure the safety and effectiveness of information flow, capital flow and logistics.
Vivid cases full of anti-epidemic elements have been applied to online teaching, which is inspiring students to create social value with professional knowledge, cultivating professional identity and enthusiasm for learning, and promoting professional teaching and ideological and political education to go hand in hand, resonate with the same frequency, and ensure quality and quantity.
