[Reprint]18832 electronic components! Nanjing University airdrops love "gift bags" to students!
"Teacher, I'm Ding Huici, a student in Taoyuan, Taiwan. I have received a gift bag! Thank you, teacher! "Teacher, I am in Xinjiang Altay ,I’ve received express delivery at four p.m., the components are all complete, thank you, teacher !" On April the 18th, on the fourth day of delivery, the most remote classmate from Xinjiang Altay region Kazakh-- Yeth Hatti Yerken sent a message said he received the package.

The reporter learned that 214 students from the College of Electronic Science and Engineering of Nanjing University received the same "gift package" from the school, a total of 18832 electronic components. This is the spring semester lessons-- "circuit analysis experiment" and "analog circuit experiment" required by the home experiment kit. Now the students "moved" the laboratory home without going back to school and canbuild circuit home.

After the online teaching of Nanjing University begins, the course of electronic experiment is faced with the dilemma of doing circuit experiments without device. Although online teaching can also be carried out in the form of software simulation, software simulation is always only simulation. The simulation results and real results of the same circuit are different due to the interference of component precision, wire contact, input signal, measuring instrument and so on. This process is not only the learning process of circuit knowledge, but also the training process of engineering practice ability, and it is also an essential link to train the leading talents of electronic innovation.

In order to ensure that the efficiency of online courses is not discounted, the national experimental teaching demonstration center of electronic information specialty (electronic experimental center) makes a good plan early. A few weeks before the start of online teaching, the electronic experimental center uses online software simulation to carry out teaching. After the express delivery resumed, the electronic experimental center immediately purchased electronic components in batches, counted and prepared the experimental boxes; the electronic experiment "love gift bag" were dropped to prepare the real experimental stage, and the mixed teaching of online and offline experiments was effectively connected.
From april the 13th, all the teachers of the electronic experiment center began to make love " gift bag" by packing electronic components and test boxes in an orderly manner.
The teachers divided the resistive capacitance and the integrated chip of different nominal values into one component package according to the requirements of the experiments. Each component package contains: 14 kinds, 52 pieces of resistance; 5 kinds, 16 pieces of capacitance; 10 pieces of diode; 2 kinds, 8 pieces of chip; 2 pieces of switch, a total of 214 components package, a total of 18832 electronic components, these devices and "pocket instrument" experimental box in storehouse of the electronic laboratory center (contains experimental box: oscilloscope, signal source, simple power supply, equipped with two doors of electronic components and cable package for students) were packaged to students together.

214 experimental kits
the courier took careful protection
Two experimental courses, circuit analysis experiment and analog circuit experiment, involve 214 students of grade 2019(including 11 elective students from other colleges), scattered in every corner of the motherland, there are Macao students living in Zhongshan City, Taiwan students in Baodao Island, the farthest student is in Altai Mountain District, Xinjiang. Through Shunfeng express delivery, experimental gift bags full of loving have arrived in the hands of the students.
214 students doing experiments at home
"Home anti-epidemiology experiment, equipment thousands of miles to meet ", "People sitting at home, express arrived from Nanjing University ", "Thousands of miles to send equipment, courtesy is more important than affection", "No conditions then we can create conditions, no components the we can mail the components!", "Can't do experiments at home? Looking at the circle of friends, a pile of lemon essence, the heart is happy like blooming flowers. The teachers finally sent out the love breadboard for more than 200 students. Thank you! !!" ……… the students show off online one after another, theattention and care from school let everyone feel warm in heart, the grade director Wang Shengyu said that the pure theory of the experimental class is really a bit" suffering ", experimental gift package let they calm down ," given such excellent learning conditions, we have no reason to slack off at home! May the epidemic be overcome early and we can return to campus early! "
Next, students can do circuit analysis experiments and analog circuit experiments with the equipment and components in the experiment box at home under the guidance of the teachers in the online classroom, the teachers explain the experiment principles online and conduct the software simulation, the students build the circuit on the bread board of the experiment box at home to measure through the pocket instrument, the measurement results are sent to the teachers for comments and analysis on the online platform.
Through the online experiments, each student will hand in the electronic experiment reports to the teacher, and the system can collect the measurement data, which ensures the authenticity of the experimental data. The combination of online and offline experimental teaching has solved the problem of experimental teaching during the epidemic situation.
