“两性一度”背景下化工热力学实验教学进阶式探索与实践

Advanced Exploration and Practice of Teaching in the Experimental Course of Chemical Engineering Thermodynamics under the“High Order,Innovative,and Challenging”Framework

在化工热力学实验教学中,通过设置进阶训练思考题,激励学生进行探索与实践。以第二维里系数的测定实验为例,倡导学生独立思考与构建高阶维里系数的方法,引导其分析比较国内外学者处理问题的策略与方法,而后辅导其通过双向检验证明所做实验数据的准确性、验证所构建方法的合理性、分析所得结果的有效性,最后指导学生理清数据处理方法的发展脉络,对其所构建的方法进行准确定位与评价。本教学实践通过强化实验教学项目的设计性与综合性,探索提升实验类课程高阶性的途径,践行“两性一度”的要求。

In the experimental instruction of chemical engineering thermodynamics,we encouraged students to carry out exploratory and practical learning through advanced,thought-provoking exercises.Taking the measurement of the second Virial coefficient of CO2 as an example,we advocated students to think and devise the methods for calculating higher-order Virial coefficients independently,guiding them to analyze and compare problem-solving strategies and methods used by scholars both domestically and internationally.Students are then coached to conduct bidirectional tests to validate the accuracy of their experimental data,the rationality of their constructed methods,as well as the effectiveness of their results.Furthermore,they are led to trace the evolution of data processing methodologies related to Virial coefficient experiments,enabling them to precisely identify and critically assess their own methodologies.By enhancing the design and integrative aspects of our experimental teaching projects,we explore ways to elevate the sophistication of experimental courses,thereby meeting and actualizing the“High Order,Innovative,and Challenging”standards.
