常态化疫情防控期间线上线下融合教学探索

An Exploration of Online-and-Offline Mixed Teaching Method During the Period of Normalized Prevention and Control of Covid-19

疫情常态化防控期间,针对返校学生和未返校学生两个群体,教师探索线上线下融合教学方式,发挥线上互动、线下投影及板书的优点进行融合教学。针对实验教学,教师充分发挥科研和教学经验,将传统硬件电路实验箱升级改造为虚实一体实验系统,返校学生和未返校学生均可进行实验,实验场景突破时空限制。针对在线考试,教师精选考试内容,调整考试时间,创新监考方式,保证考试内容合理和考试过程公平。

During the period of normalized prevention and control of Covid-19,the authors,who all teach in the School of Electronic and Information Engineering,Shandong University of Science and Technology,have explored online-and-offline mixed teaching method,which is aimed at two groups of students who have returned to school and those who haven′t.This method combines the advantages of online interaction and the advantages of offline projection and blackboard writing.Aiming at the experiment teaching,the authors,by exploiting their research and teaching experience,have upgraded the traditional hardware circuit experiment box into a virtual-real experiment system,which allows the students who haven't returned to school to do experiments on“clouds”while those who have returned are experimenting on the real laboratory spot.The experiment situation breaks the limit of time and space.Aiming at online exam,teachers can also carefully select exam content,coordinate the exam date,innovate the exam supervision manners to ensure the exam content is proper and the exam process is fair.
