虚拟仿真实验项目助力实验课在线教学

在新型冠状病毒疫情的影响下,全国高校延期开学,为实现“停课不停教,停课不停学”,各高校教师充分挖掘网络教学资源,积极开展在线教学活动。本文以山东大学虚拟仿真项目“特种高强度硅橡胶的制备与结构分析综合实验”中甲基乙烯基硅橡胶生胶乙烯基含量测定为例,介绍了无机及分析化学实验课中,如何利用虚拟仿真实验项目与在线资源结合的形式开展在线实验教学,帮助学生学习碘量法分析原理及操作。

Virtual Simulation Experimental System in Online Teaching of the Laboratory Course

Due to the outbreak of the COVID-19 epidemic, the new semester has been postponed. But in order to continue teaching and student training work, teachers from colleges are efficiently utilizing internet education resources, and actively carry out online teaching. This paper uses one of the virtual simulation experiment projects at Shandong University, as an example. It introduces how to conduct online laboratory training and teaching in inorganic and analytical chemistry laboratory by utilizing the combination of virtual simulation experiment projects and online resources, and help student learn the theory and operation of iodometry titration.
