Progressive Layered Teaching Design and Practice for All-Optical Network Transmission Technology Course — Construction and Application of Personalized Learning Paths

Addressing common challenges in the teaching of "All-Optical Network Transmission Technology" courses in higher vocational colleges—such as rapid technological updates, uneven student knowledge bases, and the disconnect between college training and enterprise demands—this paper combines teaching practices in higher vocational ICT majors. Leveraging resources from industry-education integration and school-enterprise cooperation, it explores the construction of a progressive layered teaching model adapted to full-scenario higher vocational teaching, optimizing personalized learning paths. Through core measures including reconstructing the course knowledge system, developing layered practical training projects, innovating classroom teaching models, integrating ideological and political education into the course, and iteratively updating teaching resources, significant improvements in teaching quality and students' practical abilities have been achieved. This provides universal practical references and theoretical support for the teaching reform of optical network technology courses in various higher vocational colleges.
