When people sit at home, gifts come.
"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.

The reporter learned that 214 students from the school of Electronic Science and engineering of Nanjing University have received the same "gift bag" 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.

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.
(Jiang Haiyang, Yangzhou, Jiangsu)
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.

In order to ensure the effect of online courses is not compromised, the national experimental teaching demonstration center of electronic information specialty (referred to as the electronic experimental center) of the college makes a good plan early. A few weeks before the start of the school, the electronic experimental center uses the form of online software simulation to carry out the teaching, so as to ensure the continuous filing of experimental teaching;
After the logistics returns to work, the electronic experiment center immediately purchases electronic components in batches, counts and prepares the experiment box; airdrop electronic experiment "love package" is prepared for the real experiment stage, effectively connecting 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".
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 contains 52 pieces of 14 types of resistors, 16 pieces of 5 types of capacitors, 10 pieces of diodes, 8 pieces of 2 types of chips, and 2 pieces of switches. A total of 214 component packages were divided into 18832 electronic components.
These devices are packaged and delivered to students together with the "pocket instrument" laboratory box in the warehouse of Electronic Experiment Center (the laboratory box has the functions of oscilloscope, signal source, simple power supply and other instruments, equipped with the electronic components and cables required for two experiments).
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.

"People sit at home and express NANDA. The gift is more important than the feeling. "
"Create conditions without conditions, mail components without components! People sit at home, and the equipment is coming! Can't you do experiments at home?! looking at a pile of lemon essence in the circle of friends, I feel happy. Teachers went to battle together, and finally sent out love bread board for more than 200 students. Thank you
Students have "dazzled the rich" on the Internet. The school's attention and care make everyone warm inside.
Wang Shengyu, the 2019 grade chief, said that the pure theoretical experiment class was really a bit "tormented". The experimental gift package calmed our anxious mood, "given such excellent learning conditions, what reason do we have to slack off at home! Hope to defeat the epidemic 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 laboratory box at home under the guidance of the teacher in the online classroom. The teacher explains the experiment principle and software simulation teaching online. Students can build circuit on the bread board of the laboratory box at home and offline to measure through pocket instrument. The measurement results are online platform 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.
Home based anti epidemic experiments, equipment thousands of miles to meet.
There is a kind of University. It's called another university.
Tuanzi envied! And you?

After the official account is revised, "star standard" will be more convenient for us to accept our news. Just three small steps:
Click the blue words to view the high-quality content of the history of qingtuanzi? Jiangsu University military training reward, the new students of this school are also very good-looking? "No one can praise you for making friends like you"? When someone else's boyfriend starts blowing rainbow fart, hahahaha, it's too sweet to want it!
