Design and construction of cell engineering curriculum quality evaluation system for portfolio assessment.

The article focuses on the design and construction of a curriculum quality evaluation system for a cell engineering course based on portfolio assessment, aligned with China's "New Engineering" initiative and engineering education certification standards. Using the VALUE (Valid Assessment of Learning in Undergraduate Education) rubrics as a reference, the authors developed a multi-dimensional evaluation framework emphasizing learning ability, problem analysis ability, and knowledge application ability, with detailed scoring criteria for discussions, coursework quality, and peer evaluations. The system integrates formative, diagnostic, and summative assessments, adjusting traditional grading structures to prioritize continuous performance and comprehensive skill development. Analysis of student assessment data demonstrated improvements in learning engagement and work quality, while highlighting areas for further enhancement. This evaluation model aims to provide a standardized, localized reference for engineering education quality assessment in Chinese higher education institutions.
