The “Middle School Talent Program” plays an important role in breaking through the bottleneck of selecting top innovative talents in basic disciplines and promoting the effective connection between higher education and basic education. Based on the late start and lack of experience in the implementation of the “Middle School Student Talent Plan” in Xinjiang compared with the mainland, taking the physics discipline of Xinjiang University as an example, this paper makes full use of the science popularization education resources of Xinjiang University, skillfully combines online and offline education platforms, and strives to improve the utilization rate of education resources by unifying the selection criteria, integrating education concepts and innovating training methods. We will explore a new model for training top-notch and innovative reserve talents.This model provides ideas and references for the top-notch innovative through-training of middle school students in Xinjiang and even border areas.

Solid state physics is one of hardest undergraduate courses in physics, which is also closely connected with research frontier of condensed matter physics. There have been many advances in this field over the past years, e.g., two-dimensional materials and topological insulators.Here, we summarize attempts of integrating some advances in condensed matter physics into course teaching of solid state physics, including visualization tools of crystal structures, structural construction of twisted graphene bilayers, band structure and density of states of graphene, Rashba effect and thermoelectric effects. These attempts turn out to be effective in helping students understand basic concepts and computational methods in solid state physics.
The phrase “moving magnetic field” which is problematic but commonly used by students is analyzed. It is pointed out that it makes no sense to say “the magnetic field is moving or static” and “a particle is moving relative to the field”. The velocity in Lorentz force and motional electromotive force is relative to the observer, and “the moving magnetic field” is in fact the moving source of magnetic field (magnet, for example). After this correction, moving source results in varying magnetic field, which induces the electric field. Thus, non-electrostatic force has not only (a component of) Lorentz force but also the induced electric field force, and the electromotive force also has two corresponding components. All these can be calculated within the acceptable range. The relativity of magnetic and electric fields is also emphasized. These analysis are helpful for students to grasp the transformation of electromagnetic field reference system.
