The development of digitalization, big data, and information technology has profoundly affected higher education. College and university teachers operate within a new innovative ecology, encompassing everything from the acquisition of information resources to the presentation of teaching methods across space, time, patterns, content, and pedagogy. Under the concept of comprehensive digital education, the efficient integration of curriculum expertise and professional education, supported by digital technology can enhance the digital ability and proficiency of professional course instructors in higher education and improve the goal of human education. To this end, the digital intelligence-empowered inspection model for college professional teachers’ ideological and political teaching ability inspection is constructed to enable them to diagnose and assess their own ideological and political teaching capacity and to plan the direction of their development and enhancement. Colleges, universities, and management organizations can intuitively understand the performance levels and training needs related to professional teachers’ ideological and political teaching ability, allowing them to improve this ability in a targeted and practical way.

With the depletion of energy and the increasing awareness of environmental protection, bio-polymer films will become a possible alternative to plastic packaging in the future. However, further improvement is needed in the mechanical, waterproof, anti-ultraviolet (UV), and antioxidant properties of bio-polymer films. In this work, a novel bio-polymer film consisting of gelatin, chitosan, and carnauba wax was developed by crosslinking reactions and exhibited excellent performance with appropriate mechanical strength (tensile strength 10 MPa, breaking elongation 38%), excellent water resistance properties (the contact angle reached 124°), and 2,2-diphenyl-1-picrylhydrazyl scavenging ability (69.1%) and can completely block UV rays. Consequently, carnauba wax/chitosan/gelatin film, as a new type of versatile film with excellent performance, will broaden the application of biobased polymer films in the packaging field.

Hydrogels have displayed great potential applications in biological intelligent devices, tissue engineering and electronic wearable fields. As the two most important factors limiting the application of hydrogels, strength and self‐healing ability have always been the focus of research, but the incompatibility between them has not been resolved. It is worth noting that double‐network structure and the introduction of reversible bonds show great promise as a feasible scheme to solve the above problems. Herein, the PVA/G/B double‐network hydrogels were developed by a simple synthesis process and exhibited excellent properties, including strong tensile strength (~787 kPa), high elongation at break (~200%), excellent self‐healing properties (healing efficiency exceeds 93%), good dimensional stability and transparency. This study provides an effective method for designing hydrogels with high strength, stretchability, stability, transparency and excellent self‐healing properties based on the gelatin reinforcing strategy.
