To further improve the teaching level、Improve teaching quality，Actively respond to the school’s “Teaching in Mingde” series of activities，The School of General Education held a university physics demonstration open class event on the morning of September 10, 2024，Invite Li Bin、Zou m88 online bettingDan、Three associate professors m88 best online betting websiteLi Yu gave a public demonstration class，16 other young teachers from the teaching and research section participated in this classroom demonstration observation activity。

The first person to conduct a demonstration open class was Teacher Li Bin，The content is electromagnetic induction。Teacher Li introduced it from the experiment，Emphasize that physics is an experimental science，Draw experimental conclusions based on a large number of experiments。The writing on the blackboard is concise and clear，Key formulas and concepts are clear at a glance，Train students’ ability to grasp key points and organize notes，It also gave the observing teachers a deep understanding of how to teach obscure physical theories to students in the clearest way。

Teacher Zou Dan’s demonstration lesson is about the Doppler effect of mechanical waves。Teacher Zou cleverly uses his mobile phoneApp’s function introduces the m88 best betting websitesonic Doppler phenomenon into m88 bet loginthe classroom，Enable students to intuitively experience the Doppler effect。At the same time, Teacher Zou uses self-made teaching aids，Let students better understand the reasons for frequency changes。final，Teacher Zou extended the Doppler effect of mechanical waves to the Doppler effect of electromagnetic waves，And use the contribution of Academician Ben De and his team in Doppler fire control radar to inspire everyone's sentiment of "serving the country with learning"，Integrate ideological and political courses into teaching content。

final，Teacher Li Yu’s demonstration class uses “Physical Image of Mechanical Waves” as the teaching content。Teacher Li vividly demonstrated the generation mechanism of mechanical waves through a large number of animation effects，Then explain transverse waves、Concepts such as longitudinal waves，Improved m88 slot machine casinostudents’ understanding of these abstract concepts，Set m88 online sports betting appthinking questions，Added teacher-student interaction session，Fully embodies the student-centered teaching philosophy。

Observe the teacher taking notes carefully，Record the key points, difficulties and highlights in the teaching process。The discussion session after the open class，Teachers actively discuss and speak。Teachers have expressed that teaching materials should be enriched in subsequent teaching，To broaden students’ horizons；It is necessary to enrich teaching methods，Make full use of multimedia resources to stimulate students’ interest in learning；Use more teaching aids，To deepen the depth of m88 slot machine casinostudents’ understanding。

This demonstration open class activity has a certain demonstration and promotion effect on teachers to improve their teaching concepts and teaching skills。I believe in the future teaching，Teachers m88 best betting websitewill incorporate what they learned today into their m88 online bettingown classrooms，Bringing students more excitement、Efficient college physics course，Contribute to our school’s training of applied undergraduate talents。
