生态学课程线上与线下教学效果对比研究

受新冠肺炎疫情及“互联网+”教育快速发展的影响,线上教学已成为高校师生教与学的必选方式。然而,各地线上教学效果参差不齐,开展线上和线下教学效果的对比研究有助于为当前疫情防控期间教学模式的选择和教学活动的开展提供理论和实践指导。生态学是一门高度综合的交叉学科,时代性强,知识内容更新快。通过对两个教学班分别开展生态学课程的线上和线下教学效果对比研究发现,其教学效果存在显著差异,具体表现为线下教学的平时成绩和期末成绩均要显著高于线上教学中的两项成绩。通过调查问卷发现,其主要原因在于线上教学过程中学生的自控力不足、教学互动不足及部分学生缺乏课前预习习惯等。为解决以上问题,充分利用线上和线下教学的优势,在今后的教学实践过程中,宜采取线上与线下混合式教学模式。

With the impacts of coronavirus pandemic and the rapid growth of"Internet plus"education,online learning has become the imperative choice for teachers and students in universities.However,the performance of online learning is various,and then,comparing the differences between online learning and in-person learning could help provide theoretical and practical guidance for teaching approaches and activities during the outbreaks of COVID-19.Ecology is ahighly integrative and interdisciplinary science,with the characteristics of strong timeliness and the rapid renewal of knowledge.Through separately conducting online learning and in-person learning on ecology in two different classes,we found that there were significant differences in efficiencies of these two kinds of teaching approaches,and the usual performance and final grade of in-person learning was significantly higher than those of online learning.Further study on the consulting,we found that the main causes for the problems in online learning are the shortages of self-control,the interactivities between teachers and students,and the preview before lesson.To solve the above problems and take full advantage of superiorities of these two teaching approaches,we suggest that the combination of online and offline teaching is the best choice for the following teaching practice.
