Abstract: This article takes the database system course at Huizhou University as an example to explore the design and application of a project-based learning evaluation system based on key competencies; Based on the concept of deep learning and engineering certification requirements, 12 key competencies (such as self-learning, communication and collaboration, solution design, etc.) were extracted, and a real project case library was constructed through cooperation with enterprises. The course content was divided into 5 milestone stages for promotion. The course adopts a multi-dimensional evaluation model of “knowledge ability literacy”, integrating process evaluation, value-added evaluation and other methods, and developing an intelligent platform for learning portrait drawing and ability tracking. Practice has shown that this evaluation system effectively enhances students' comprehensive abilities, and some student projects have won national competition awards and venture capital, verifying its effectiveness in promoting deep learning and key ability cultivation.
