Innovative application of generating instrument operation videos using QR code technology in experimental teaching

Objectives As an indispensable part of the higher education system, experimental teaching aims to cultivate students’ practical skills, problem-solving capabilities, and innovative thinking. However, traditional models exhibit significant limitations, including uneven resource distribution, constrained operational demonstrations, and disparities in student comprehension. This study explores an innovative experimental teaching model employing Quick Response (QR) codes to enhance instructional efficacy and quality. Methods The proposed methodology employs QR codes to generate instructional videos for integration into experimental teaching. This approach transcends temporal and spatial constraints, enabling students to access instructional videos on demand. Results This technology-enhanced model facilitates mastery of instrument operation via on-demand video access, yielding the following outcomes: (1) improved efficacy and quality of experimental teaching; (2) flexible learning platform bridging theoretical knowledge and practical operations; (3) mitigation of issues of resource disparities and practice limitations inherent in traditional models; and (4) enhanced professional skills of students through self-paced repetition. Conclusions The study demonstrates that QR code technology drives innovation in experimental teaching reform. It effectively addresses traditional methodological constraints, improves instructional efficiency, and fosters optimal conditions for holistic student development.
