疫情防控背景下在线教学在口腔医学教育中的应用

Application of online teaching in stomatology education under the background of COVID-19 epidemic prevention and control

目的了解并比较口腔医学专业和口腔医学技术专业学生在新型冠状病毒肺炎疫情防控期间在线学习情况,分析在线教学的优势和挑战,为口腔医学教育教学模式的改革提供参考。方法选择重庆医科大学口腔医学专业的267名学生和口腔医学技术专业的92名学生为研究对象,开展在线学习问卷调查。采用SPSS 21.0统计软件包对数据进行分析,计数资料行卡方检验或者秩和检验。结果电脑和手机是学生在线学习的主要工具,52.92%的学生使用电脑,38.72%的学生使用智能手机;约80%的学生表示比较适应或者适应线上学习,两专业学生比较没有统计学差异;口腔医学专业学生在线学习时间主要为4~6 h,口腔医学技术专业学生为2~4 h,差别具有统计学意义;口腔医学技术专业学生比口腔医学专业学生更喜欢向教师提问,经常向教师提问的学生占比分别为29.35%和20.60%,差别具有统计学意义;两专业均有少部分学生不能按时登录平台学习和完成所有教学资料的学习;超过50%的学生认为线上教学不及线下教学的教学效果,认为线下教学更利于掌握课程知识,两专业学生回答没有统计学差异;学生认为学习平台不顺畅、家里网络条件不好和教师准备的资料不足是影响在线学习效果的主要原因。结论在线教学是新型冠状病毒肺炎疫情防控期间维系教学工作的重要可取途径。正确合理利用信息化技术,结合在线教学和传统课堂教学的优势,从专业和课程的特色出发,积极探索混合式教学是今后课程组教育教学改革深入研究的方向。

Objective To understand and compare the online learning effect of students majoring in stomatology and dental technology under the background of COVID-19 epidemic prevention and control,and to analyze the advantages and challenges of online teaching,so as to provide reference for the reform of teaching mode of stomatology education.Methods A questionnaire survey on online learning was carried out among 267 students majoring in stomatology and 92 students majoring in dental technology in Chongqing Medical University.The results were statistically analyzed by SPSS 21.0,and chi-square test or rank sum test was used to count the data.Results Computers and mobile phones are the main tools for students to study online.52.92%of students used computers and 38.72%used smart phones.About 80%of the students said that they could adapt to online learning,and there was no statistical difference between the students of two majors.The online learning time of students majoring in stomatology was mainly 4-6 hours,while that of students majoring in dental technology was 2-4 hours,with statistical significance.However,the latter were more likely to ask questions to teachers than the former,and the proportion of students who often asked questions to teachers was 29.35%and 20.60%,respectively,with statistical significance.A small number of students of both majors failed log on the platform to learn and complete all the teaching materials on time.More than 50%of the students thought that online teaching was not as effective as offline teaching,and offline teaching was more conducive to mastering curriculum knowledge,without statistical differences between the students of two majors.They thought that the unsmooth learning platform,poor network conditions at home,and insufficient teaching materials prepared by teachers were the main reasons that affected the online learning effect.Conclusion The online teaching is an important and also an advisable way to maintain teaching activities during the epidemic prevention and control of COVID-19.It will be the direction of further research on the education and teaching reform to make full use of information technology,combine the advantages of online teaching and traditional classroom teaching,and actively explore the blended teaching mode from the perspective of specialty and course characteristics.
