The Undergraduate Student Initiated Education (USIE) program at the University of California, Los Angeles (UCLA) is an innovative program that selects outstanding senior undergraduates to develop and teach courses around a topic of their choice under the guidance of a mentor. From the proposal of students to the final permanent education program of UCLA, this project has lasted for ten years after rigorous demonstration and long - term experiment, and is a relatively successful “student - centered” curriculum inno? vation project. From the perspective of “student - centered ecosystems” (SCE), the success of USIE is inseparable from its multi - di? mensional unity in the aspects of curriculum power sharing, teaching support provision, program quality assurance, management system integration and policy culture reconstruction. In the process of building a student - centered first - class undergraduate curriculum, at? tention should be paid to the systematic promotion of curriculum innovation from the aspects of curriculum development, teaching sup? port, quality assurance, system of management and policy culture. In particular, it is necessary to strengthen student empowerment, enhance organizational governance, pay attention to quality monitoring, and promote cultural recreation. So that student - centered re? form does not stay in a single element or dimension such as concept slogan, role transformation, relationship reconstruction, but be? comes a cultural ethos dispersed in the whole university organism.
