Abstract: In context of emerging engineering education, China places high importance on exploring teaching management models exploration for cultivating interdisciplinary talents in agricultural engineering．With in-depth application of information technology in course teaching, blending teaching（online and offline）process management has become a new trend．Traditional summative assessment method's drawbacks and need for course process management in course were elaborated．Implementation of blended teaching process management for PLC Principles and Applications course was explored, a diversified evaluation system dominated by process-based assessment was constructed．Rain classroom platform was used to record process assessment data and refine process evaluation points such as signing in, simulation experiments, chapter tests, and other points．Diversified evaluation system implementation was analyzed, and teaching process management effectiveness in PLC Principles and Applications course was summarized, to provide references for process management teaching reform in a new era．
