On April 18, on the fourth day of sending out, yesiharti yerken, a Kazak student in the most remote area of Altay, Xinjiang, received the express message. 214 students who studied circuit analysis experiment and analog circuit experiment in the spring semester of School of Electronic Science and engineering of Nanjing University received the home-based experimental suite from the school, and the students could finally build it at home Circuit experiment.
In order to prevent and control the spread of the new epidemic, all major universities across the country are suspended from starting school. Nanjing University responds to the call of the Ministry of education to "stop teaching and stop learning" and carry out online teaching. The school of electronic technology sends equipment to students, so that students can move the laboratory home and work as a laboratory at home.

"Teacher, I'm Ding Huici, a student of Taoyuan in Taiwan. I have received the gift pack! Thank you "Teacher, I received the express delivery at 4:00 p.m. in Altay, Xinjiang. All the components are complete. Thank you." On April 18, on the fourth day of sending, yeshhati yerken, a Kazak student from Altay, the most remote area in Xinjiang, sent a message of receiving express delivery.
Student Ding Huici, Taoyuan City, Taiwan received the gift bag
The reporter learned that 214 students from the school of Electronic Science and engineering of Nanjing University have received the same "gift pack" from the school, with a total of 18832 electronic components. This is the home experiment kit for studying circuit analysis experiment and analog circuit experiment in spring semester. Students have moved the lab back home, and can also build circuit experiment without returning to school.
214 test kits
After the online teaching in Nanjing University, the electronic experiment course is faced with the dilemma of doing circuit experiments in the middle of nowhere. According to Zhang Zhijian, a teacher from the school of electronics of NaNTU, although online teaching can also be carried out in the form of software simulation for electronic information experiment courses, software simulation is always just simulation. Due to the interference of components accuracy, wire contact, input signal, measuring instrument and other factors, the simulation results and real results of the same circuit will be different. Qualified electronic workers Engineers must have the ability of circuit design, by adjusting circuit parameters, eliminating interference, and designing a stable and reliable circuit. This process is not only the learning process of circuit knowledge, but also the training process of engineering practice ability. It is also an essential link to train leading talents of electronic innovation.
214 students are experimenting in the cloud
In order to ensure that the effect of online courses is not compromised, the national experimental teaching demonstration center of electronic information specialty of the College (Electronic Experimental Center for short) made a plan early. A few weeks before the start of the school, the electronic experimental center carried out the teaching in the form of online software simulation to ensure that the experimental teaching is kept on file; after the resumption of logistics, the electronic experimental center immediately purchased electronic components in batches Count and prepare the experimental box; air drop electronic experiment "love pack", prepare for the real experiment stage, and effectively connect the mixed teaching of online and offline experiments.
From April 13, all teachers of the electronic experiment center began to pack electronic components and experiment boxes in an orderly manner to make "love gift bag".
Students express surprise in personal cyberspace
According to the requirements of the experiment, the teachers divided the resistors, capacitors and integrated chips with different nominal values into one component package. Each component package includes 14 kinds of resistors, 52 pieces of capacitors, 5 kinds of capacitors, 16 pieces of diodes, 10 pieces of chips, 2 kinds of chips, 8 pieces of switches, totally 214 component packages, totaling 18832 electronic components. These components and the pocket instrument in the warehouse of Electronic Experiment Center The "apparatus" experimental box (there are oscilloscope, signal source, simple power supply and other instrument functions in the experimental box, equipped with the electronic components and cables required for two experiments) is packed and delivered to the students together.
Circuit analysis experiment and analog circuit experiment are two experimental courses involving 214 students (including 11 elective students from other departments) of electronic college in 2019. They are scattered in every corner of the land of the motherland. There are Macao students living in Zhongshan City, Taiwan students living in Baodao, and the farthest students in Altai Mountain area of new Xinjiang. Through Shunfeng express, the experimental packages full of love have arrived at the students one after another Hands.
"Home anti epidemic experiment, equipment thousands of miles to meet" "people at home, express NANDA. Thousands of miles to send equipment, the gift is more important and the feeling is more important. "" create conditions without conditions, mail components without components! People sit at home, the equipment is coming! Can't do experiments at home?! watching a pile of lemon essence in the circle of friends, the heart is happy with flowers. ". Teachers went to battle together, and finally sent out love bread board for more than 200 students. Thank you Students showed off their wealth on the Internet in succession. The school's attention and care made everyone warm inside. Wang Shengyu, the 2019 grade chief, said that the pure theory experiment class was really a bit "tormented". The experimental gift pack calmed our anxious mood, "Given such excellent learning conditions, what is the reason for us to slack off at home? We are willing to defeat the epidemic as soon as possible and return to campus as soon as possible!"
Next, 2019 students can do circuit analysis experiment and analog circuit experiment with the equipment and components in the experimental box at home under the guidance of the teacher in the online classroom. The teacher explains the experimental principle and software simulation teaching online. Students can build circuits on the bread board of the experimental box offline at home and measure the results through pocket instruments. The online platform is provided for the measurement results Send it to teachers for comment and analysis.
Through the online experiment, each student will submit the electronic experiment report to the teacher. The system can collect the pocket instrument measurement data, ensuring the authenticity of the experimental data. The combination of online and offline experimental teaching solves the problem of experimental teaching during the epidemic.
