提升新冠疫情期间网络教学效果的途径研究

Research on Ways to Improve the Effect of Network Teaching during the Covid-19 Epidemic

2020年1月新型冠状病毒在我国大江南北肆虐,它直接导致了2月份全民生活轨迹发生了变化,或是时间变化,或是线路变化。为了避免大规模人群聚集有效控制疫情,政府不断出台相应的措施,包括延迟各大中小学及幼儿园的开学时间。非常时期必要的防控手段,客观上影响了学生的正常学习。为此,教育部号召大家“停课不停学”,改变授课方式,主要是利用各大网络平台进行远程授课。但以往信息化教学更多是作为常规教学的有效辅助手段出现的,也有少数是在不方便现场教学的情况下采用的。另外,还存在技术问题,比如线上人数过多、平台负荷过大、通讯信号不稳定、导致课程直播中卡顿无法流畅观看等。为了更好地利用网络资源,达到理想的教学效果,实现教学目的,从网络教学资源、教师授课时长、网络负荷等几方面入手研究,提出相应的解决途径和方法,以期能够为类似上述非常时期的教学工作合理进行提供帮助。

In January 2020,Covid-19 raged across China,which directly led to the change of the life track of national activities in February,a change in time or in line.In order to effectively control the epidemic and avoid mass population gathering,the government has continued to introduce corresponding measures,including delaying the opening hours of major colleges,high schools,junior high schools,primary schools and kindergartens.The necessary prevention and control measures in the period of fighting the virus objectively affect the students normal study.For this reason,the Ministry of Education has put forward the call of“suspending classes and not stopping studies”,and correspondingly changed the teaching methods,using the major network platforms to carry out distance teaching.In the past,the information teaching is more as an effective auxiliary means of normal classroom teaching,and is also adopted in a few inconvenient on-site teaching situations.In addition,there are technical problems,such as too many people online,too much platform load,unstable communication signals,resulting in the course live broadcast cannot be watched smoothly.In order to make better use of the network resources,achieve the ideal teaching effect and achieve the teaching purpose,this paper studies the network teaching resources,teachers teaching time,network load and other aspects,and puts forward the corresponding solutions and methods,in order to provide reasonable help for the teaching and learning work in the above abnormal period.
