Abstract: This article upholding the educational philosophy and requirements of“student-centered and competency-oriented”, we have improved the assessment methods for the separation technology module experimental course. A diversified process assessment system encompassing pre-class, in-class, and post-class evaluations has been established. This includes the addition of pre-class preparatory quizzes, the strengthening of in-class experimental operation assessments, and post-class experimental report evaluations. Furthermore, in-class questioning assessments and post-class homework evaluations, combined with theoretical and practical examinations, allow for tracking and evaluating students at various stages of their experimental course learning. This approach is beneficial in stimulating students'curiosity, enhancing their practical innovation capabilities and scientific literacy, thereby promoting the improvement of their professional competencies.
