Abstract: To address the prominent challenges in practical teaching for chemistry and chemical engineering majors at local universities, including limited teaching resources, outdated content, simplistic evaluation methods, and insufficient quality monitoring, we have developed a novel practical teaching system focused on student competency development. This system, termed “Three Lines Through and Three Layers Progressive,” implements comprehensive reforms through multiple dimensions: reconstruction of teaching content, transformation of teaching evaluation, establishment of quality assurance mechanisms, and collaborative integration of teaching resources. Our research demonstrates that this system effectively bridges the gap between practical teaching content and industrial production technologies while aligning with the forefront of disciplinary development. It explores a comprehensive assessment mechanism based on a practical skills target matrix and establishes a closed-loop quality assurance system encompassing “decision-making, implementation, evaluation, and improvement.” Furthermore, it promotes deep integration of teaching and research platforms across colleges, universities, and enterprises. The implementation of this system has yielded significant teaching outcomes, facilitating the transformation of chemical and chemical engineering education from traditional, basic levels to developmental, innovative, and entrepreneurial levels. This model provides a replicable framework for cultivating new engineering talents in local universities.
