混合式教学模式下提升验证性实验“两性一度”的探索与实践

Exploration and Practice of Improving “High-level, Innovation andChallenge” of Confirmatory Experiment under Blended Teaching Mode

以地层油高压物性测定实验为例,开发数字化教学资源、建设网上虚拟课堂。利用线上线下混合式教学突破实验教学时间和空间的限制,拓展实验内容,涵盖了地层油取样、配样、转样、测试及分析等全过程的系统知识,并紧跟石油工程领域前沿研究热点引入部分CO_(2)驱油和封存机理研究内容,将原验证性实验改进为探究性实验。构建以学生为主体的翻转实验教学模式,在课前、课中及课后多个环节实施“教师+学生”“过程+成果”“常规+拔高”相结合的多元成绩评价机制。这些举措有效地解决了传统实验教学中存在的一些不足,提升了验证性实验的“两性一度”,提高了石油工程实验课程的含金量。

Taking the high-pressure property determination test of formation oil as an example,digital teaching resources are developed and an online virtual classroom is constructed.The online and offline blended teaching is used to break through the limits of teaching time and space,expand the experimental contents to cover the processes of oil sampling,preparing,transferring,testing and analyzing.A part of the research on carbon dioxide oil flooding and storage mechanism is integrated to the experiment to closely follow the frontier research hotspots in the field of petroleum engineering,so as to improve the original confirmatory experiment to an exploratory experiment.A student-oriented flipped experiment teaching mode is constructed,in which a multi-dimentional assessment method of“teacher+students”,“process+results”and“normal+difficult”implemented in the stages of pre-class,at-class and afterclass is used to evaluate the experimental score.These measures effectively solve some problems existing in the traditional experimental teaching,improve the“high-level,innovation and challenge”of the confirmatory experiment,and increase the“gold”content of the petroleum engineering experiment course.
