摘  要：受新冠肺炎疫情影响，全国各级各类学校为解决延期开学阶段学生的居家学习问题，纷纷组织师生开展在线教学工作。实验动物学属于多交叉的学科，具有知识广且随专业不同着重点不同的特点。我校实验动物学教研室以超星学习通平台为载体，理论课采取统一上课模式（速课+答疑+课后作业）完成各章节内容。速课为每位教师重点发力对象，将知识点进行切割后分别录屏，按学生专业需求进行组合上课，辅以课堂答疑进而打破师生沟通空间障碍。学生灵活点播录屏，能有效错开网络高峰从而避免焦躁心理。同时，方便重点学习或反复学习。实验课基本操作部分采取现有资源视频展示，部分需要拓展的个别实验课程申请返校后线下完成。总体来说，这种简化的上课模式师生均能很快接受并进入上课状态，教学效果良好，值得进一步推进与完善。

Abstract： Influenced by the COVID-19， in order to solve the study problem at home of students in the extended stage before school opening， various schools of each level all over China are successively organizing teachers and students to carry out the online teaching work. Laboratory Animal Science is an interdisciplinary subject featured by the vast range of knowledge and the different focuses of different majors. With superstar learning platform as the carrier， our school's teaching and research office of Laboratory Animal Science adopts the unified class mode （quick class + question answer + assignment） to accomplish the contents of each chapter of theory class. Quick class is the key target of each teacher. The teachers divide the knowledge points and record the screens respectively to offer combined class according to students' professional demands and further break the space barrier of communication between teachers and students assisted by class Q&A. The students can flexibly play the screen recordings to effectively stagger the network peaks， avoid anxiety and facilitate repeated or targeted study. As for the basic operation section of experimental class， video display of existing resources is adopted and some experimental classes requiring expansion can be accomplished offline after returning to school through application. Generally speaking， both teachers and students can rapidly accept the simplified class mode and enter the class status. It shows good teaching effects and is worthy of further promotion and perfection.

自2019年12月新型冠狀病毒肺炎（Corona Virus  Disease 2019，COVID-19）疫情以来，面对疫情防控的严峻形势，全国各省、市、自治区等相继启动公共卫生I级响应制度[1]，各地实行严格交通管制，同时全国高校开学时间也不断推迟[2]，大量返乡大学生滞留家乡，实行严格居家隔离。实验动物学是生命科学领域一门新兴的基础性学科，它在自然科学基础上综合了医学、动物学、胚胎学、生物遗传学等诸多学科理论知识和研究成果，知识体系不断交叉整合，又互相融合[3]。受新冠肺炎疫情影响，全国各级各类学校为解决延期开学阶段学生的居家学习问题，纷纷组织师生开展在线教学工作。各教学单位充分利用在线教育平台和资源，结合各种形式的教学手段做到“停课不停学”[4]。由于实验动物学是多交叉的学科，涉及理论与实践知识非常广泛，而现有的在线资源积累相对很少。从教师层面来说，在线教学教师需要重新编排知识体系，同时还需提高网络技术。从学生层面来说，在家学习缺乏学习氛围，还可能面临网络压力。因此，如何让每位学生安心在家上好这门课程面临很多的考验。因此，本文旨在探讨新冠肺炎疫情下如何应用网络在线平台实现实验动物学课程教学。
