　　On September 7, the 104th birthday of Academician Shen Panwen, an inorganic chemist and chemistry educator in my country.

He has stood on the podium for more than 70 years in his life, created the record of "China's longest teaching chemistry teacher", and set a number of firsts in the field of chemistry education and research in my country: He wrote the first Chinese chemistry book in my country Teaching materials; developed the first generation of nickel-hydrogen batteries in my country; the first to apply computer technology in chemistry teaching; presided over the completion of my country’s first multimedia chemistry textbook software; the earliest research on metal hydride chemistry, etc.

　　Speaking of my country's first multimedia chemistry textbook software completed under the auspices of Shen Panwen, we have to start in 1995.

　　At that time, American universities had used computers for more than ten years, while many universities in China did not have computers.

When Shen Panwen was visiting abroad, he saw this gap, and he came up with the idea of ​​"using multimedia programming technology for teaching reforms and developing world-class modern teaching software".

　　"You gave me the periodic table of chemical elements to'change' it into the computer." Che Yunxia, ​​now a professor at the School of Chemistry of Nankai University, still clearly remembers the "doctoral dissertation" the teacher assigned to herself when she followed Shen Panwen to study for her doctorate. topic.

　　Seeing the surprised expressions of the students, Shen Panwen explained: "I can learn at this age, and you can learn too." So, at the age of 79, he led a group of doctoral, master and undergraduate students, using computer technology to learn from the past. Means for transformation.

　　They learn programming and develop software from scratch.

In a 40-square-meter laboratory and a 20-square-meter office, Shen Panwen led 30 students into intense work.

　　While writing the electronic textbook scripts, they made the contents of the scripts into multimedia courseware.

Every time a chapter is written, the Shen Panwen must be reviewed and revised in detail. After the final draft, teachers and students will learn, discuss, and program, and the compiled courseware will be used in teaching.

　　After 3 years of hard work, in 1998, the software was finally completed.

　　At the beginning of 1999, the textbook "The Department of Chemical Elements Cycle" was officially published by Higher Education Press, and was later selected as the first prize of the 2001 National Excellent Teaching Achievement.

Subsequently, the electronic version of the textbook was also officially published. This set of software containing more than 600,000 Chinese characters, more than 4,000 pictures and more than 1,000 animations, adopts a human-computer dialogue method, with the periodic table as the main menu, and the structure of various elements through three-dimensional The animation demonstrates vividly, showing the rich and lively teaching content.

　　The "Chemical Element Period" textbook software is not only China's first multimedia textbook, but also an international innovation.

　　They donated this software to many universities in China. The teaching practice of Peking University has proved that students can use this software to study on their own, thus reducing the first-year chemistry class time by half.

Academician Zhu Qingshi of the Chinese Academy of Sciences commented: "This achievement represents the level of multimedia teaching and research in our universities." Later, Shen Panwen translated the software into English and published it.

　　"No science can create new substances like chemistry, so chemistry is a science that creates a new world." Shen Panwen's advancing with the times is never just a talk.

In 2007, Shen Panwen was 91 years old. He also opened an "education blog" and published 10 journals in one month to set an example for young people.

　　On July 4, 2017, Shen Panwen passed away in Tianjin at the age of 101.

　　"Mr. has passed away, and the spirit will live forever. We must not only remember his sweat for the education of the motherland, but also inherit the spirit of scientists who have the courage to innovate and live to learn to build a more prosperous future for the motherland." Of students wrote.
