Taking open-ended physics problems derived from daily life as the research object, this study systematically summarizes, classifies, and integrates the competition questions of the International Physics Olympiad (IPhO) and the International Young Physicists’ Tournament (IYPT). On this basis, self-developed demonstration experiment projects and supporting materials integrated with Ideo-Political elements are constructed, which deeply incorporate Ideo-Political connotations—including the spirit of scientists, scientific thinking, the feelings of serving the country through scientific research, and traditional Chinese science and technology culture—into demonstration experiments characterized by being close to daily life, highly interesting, and exploratory. The established demonstration experiment project database, which integrates Curriculum Ideo-Politics with an international perspective, effectively enriches the supply of university physics demonstration experiment resources, strengthens the coordinated cultivation of students’ scientific literacy and Ideo-Political accomplishment, and realizes the organic unity of knowledge impartment, ability training, and value shaping. This research provides a practical path and reference paradigm for the teaching reform of university physics demonstration experiments and the in-depth advancement of Curriculum Ideo-Politics construction in related fields.

This paper uses the Python language as a foundation to digitally improve the Abbe imaging principle and spatial filtering experiments. By simulating the imaging of light beams after passing through a grating in the spatial filtering experiment and undergoing Fourier transformation, and leveraging the advantages of digital improvement, it is possible to massproduce and personalize gratings and slits. By using a laser engraving machine to engrave the designed digital grating images, and placing the engraved grating patterns in the optical path of the Abbe imaging principle and spatial filtering experiments, personalized optical control patterns can be obtained.

Relying on the Tianjin Science Popularization Base and the Physics Demonstration Laboratory of Nankai University, this paper explores the implementation path of science popularization base construction in universities through three dimensions “laboratory construction,” “science popularization education courses,” and “science popularization comprehensive practice,” and constructs an integrated implementation plan for science popularization education. It also introduces the expansion of interesting physics experiments as a science popularization case, promoting close cooperation and effective connection between higher education and basic education.

The education mode of physics tournament based on OBE theory is designed and practiced, in order to cultivate the comprehensive quality of physics talents in all directions. The outcomes goals of the education mode consist of learning, innovation, practicing, communication, scientific spirit, and moral education. Teaching courses, evaluation methods and auxiliary supports are designed implemented to realize the all-round integrated teaching objectives. Through years of practice and exploration, it has been proved that this precise and real-time feedback education model can achieve sustainable and benign development, and has achieved remarkable educational results. This model has been adopted and implemented by many universities and middle schools, which has promoted the close cooperation and effective connection between middle schools and universities.

In this paper, the forced vibration of a steel string fixed at both ends under the action of an electromagnet with alternating current is studied. The spatial distribution of the magnetic field and the lateral force with a Gaussian distribution on the string are simulated, and the vibration of the steel string is calculated based on the non-homogeneous string vibration equation. At the same time, the vibration of string is observed and measured by a self-organized experimental device, and studied from three aspects: the waveform, vibration amplitude and vibration frequency of the forced vibration of the steel string. It is found that here is a stable “standing wave” mode in the waveform of steel string vibration driven by periodic electromagnetic force, and the vibration amplitude of the steel string is significantly attenuated when the driving force frequency deviates from the natural frequency of the steel string. The experimental results show that the vibration frequency of the steel string is twice the frequency of the alternating current of the electromagnet under certain conditions.
