“过程全面精准”考核在化工原理实验课程中改革与探索

doi:10.3866/PKU.DXHX202309087

Abstract

Abstract:

In response to challenges such as homogeneity of assessment methods and low student engagement in current Chemical Engineering Principle Experimental Course teaching, this study introduces virtual simulation and "Internet +" technologies into the curriculum. A novel "blended online-offline " teaching model has been constructed, implementing a level-based learning approach. The syllabus assessment points are meticulously detailed and scores are allocated step-by-step. A differentiated teaching approach is applied to certain experiments with scoring based on weight, forming a comprehensive assessment system. For the offline experiments, online control of scoring is employed, allowing students to view their grades at any time and adjust their learning status accordingly. Furthermore, an online robot Q & A platform has been established to facilitate real-time problem-solving, thereby realizing full-process teaching. This enhances the quality of Chemical Engineering Principle Experimental Course teaching, and contributes to the innovative reform of higher education in China.

Key words: Chemical engineering principle experiment, Virtual simulation, "Comprehensive and precise process" assessment
