2021-11-26
"The 2019 Nanjing Primary and Secondary School Experimental Teaching Lesson Competition" has come to an end. Who will win the laurel? On November 8, the result of the competition was officially announced. After district-level recommendation, expert review, on-site lecture and other links, 27 teachers won the first prize list. It is worth mentioning that among the 27 teachers, Lu Jingjing (junior high school biology) of Nanjing Communist Youth League Road Middle School, Hu Yuan (junior high school biology) of Xincheng junior high school affiliated to Nanjing Normal University, and Yang Yi (senior high school biology) of Nanjing No.14 middle school have received strong support from Jiangsu Suweir Technology Co., Ltd.
So, what is their magic weapon? Next, let's talk about their "story".
1 Teacher Hu Yuan: Jointly Develop Digital Experimental Instruments with Suwell and Bones out All Difficulty for Students
Lecture topic: "Experiment: Earthworms Climb Fast on What Surface"
When learning the second chapter of the biology textbook in the first volume of the seventh grade, "Exploring Life", "What kind of objects do earthworms climb fast on the surface", the students began to think: From the perspective of life experience, earthworms climb fast on rough surfaces. After discussion, they decided to use glass plates (smooth) and cloth (rough) for control experiments. The results can be imagined, but such experimental results have errors, and can not draw scientific conclusions, they encountered the following two problems:(1) earthworms crawling is not a straight line;
(2) The time used by earthworms to crawl the same distance is not accurate.
In line with the attitude of being responsible for experimental teaching and students, Mr. Hu came up with the idea of developing related experimental devices, which coincided with Suwell's research and development concept, so the two sides joined hands to embark on the road of cooperative research and development.
Everything comes to him who waits, and the prototype of the Suwell earthworm movement speed test device was successfully born. In September 2017, Mr. Hu successfully started the class with this instrument in the classroom teaching demonstration activity of "teaching experiment project in Nanjing network and digital environment", which was well received by the judges.
In the experimental operation process, it is necessary to equip the bracket in the assembly process of the crawling track and the photoelectric door, which is difficult to assemble. In order to solve the difficulties encountered by students in the experimental operation, the whole team spared no effort to continue to improve and optimize the experimental instruments.
In the 2019 Nanjing primary and secondary school experimental teaching lecture competition, Mr. Hu took the wisdom crystallization of students, teachers and Suwell-the Suwell earthworm movement speed experiment device to make a brilliant debut. The experimental device provides an open track, which can realize one-way crawling of earthworms, has a built-in photoelectric door sensor, accurately measures the crawling time of earthworms, and is equipped with three contact surfaces with different roughness, which is convenient to explore what kind of object surface earthworms crawl fast on. Supporting special software, easily measured experimental data. Provide a blank track to facilitate students to explore independently, expand students' thinking level, and meet the development needs of higher level students.

Teacher yang yi: change the traditional experimental method and use the suwell digital experimental instrument to visually demonstrate photosynthesis
Lecture Topic: Photosynthesis Exploration Experiment Based on VR and Digital Sensor Technology
Photosynthesis is a magical process. Spring and autumn, the growth of all things depends on photosynthesis. However, the photosynthesis within reach is just a stiff and cold high-frequency test site in the eyes of students, just an important and difficult point for them to roll in the sea of questions. How can the knowledge of photosynthesis be presented more intuitively to help students explore science? This is a problem that Mr. Yang Yi has always wanted to solve, and it was not until he used the Suwell Photosynthesis Experiment Box and fiber optic spectrometer that he was suddenly enlightened and discovered a broader world in the experiment.
In the traditional photosynthesis experiment, the leaves of photosynthesis will be decolorized and iodine-potassium iodide solution will be added. However, this can only be judged by observing the color change of the reagent to determine the amount of starch produced in the leaves, and then explore the effects of different light quality and carbon dioxide on the rate of photosynthesis.
However, Mr. Yang changed the traditional experimental method and quantitatively explored the effects of different light quality conditions and carbon dioxide concentration on photosynthesis rate by measuring carbon dioxide and oxygen released per unit time with the help of Suwell photosynthesis experiment box. The absorption spectra of photosynthetic pigments in different plant leaves were quantitatively explored by using Suwell fiber optic spectrometer. At the same time, through the Sowell digital experimental software, the collected experimental data are displayed visually in the form of charts.

It is intended to guide students to quantitatively explore life phenomena, and then cultivate students' ability to use digital experimental instruments to carry out scientific inquiry on life phenomena, cultivate students' scientific thinking, find the relationship between related factors behind life phenomena, and establish the concept of life that life phenomena are interrelated and affect each other.
From the perspective of students, both Mr. Hu and Mr. Yang solve experimental problems for students, lead students to explore the law of life, make students have a deeper understanding of life phenomena, and cultivate students to establish scientific thinking. it is necessary to have qualitative perception of things, but also quantitative analysis.
