Abstract: Against the backdrop of the “Internet Plus” initiative, this study explores the development and application effectiveness of a digital teaching evaluation system for organic chemistry practical courses, aiming to innovate traditional practical teaching models and enhance students’ learning initiative and practical skills. Using 2023 cohort pharmacy students at Guizhou Health Vocational College as research subjects, a teaching model integrating “video preview + independent hands-on practice + simulation” was constructed, along with a digital evaluation system comprising “points for practical theory learning + tripartite video review + value-added evaluation of skills competitions”. Teaching was conducted under a tripartite system consisting of video micro-lesson guidance, simulation-based virtual operations, and access control-enabled open practical access. Based on scoring criteria designed for skills competitions, tripartite evaluation was combined with value-added evaluation of skills competitions to assess students’ comprehensive skills. The results show that compared with the traditional teaching model, the digital teaching evaluation system significantly improved the accuracy of hands-on operations, encouraged students to voluntarily extend their practical time, and achieved a student satisfaction rate of over 90%. This system achieves an organic integration of process evaluation and outcome evaluation, providing transferable experience for practical teaching reform.
