On August 27, 2020, the 2020 junior high school science backbone experimental teachers training organized by the Teacher Training and Teacher Education Department of Changde Education Bureau and Changde Teaching Instrument Station was grandly opened in the ancient city of Changde. Yuanda-llongwill provided full support for the training. More than 100 teachers from districts and counties participated in the training.

Mr. Ling Yufeng, a physics teacher from Wuhan Jiangang middle school and expert in self-made teaching aids in Hubei Province, shared special topic with the teachers from the aspects of textbook experiment analysis, self-made teaching aids, and the comparison of digital experiments and traditional experiments with the theme of "The application of Physics Innovative Experiments and Digital Experiments".

During the training, Mr. Ling also used llongwill^® digital experimental equipment demonstrated experiments such as electrostatic measurement, exploring the relationship between force and reaction force, and the relationship between fluid pressure and flow velocity. He introduced the application and advantages of digital experiments in physics experiment teaching in simple terms, and gave a wonderful speech on how to innovate experimental teaching and improve self-made teaching aids.

After class, the teachers didn’t want to leave. Digital experiment provides more experimental choices and directions for front-line teachers, solves many difficulties in daily experimental teaching, and expands the vision of teachers.
