摘? 要：受新冠肺炎疫情影響，全國各級各類學校為解決延期開學階段學生的居家學習問題，紛紛組織師生開展在線教學工作。實驗動物學屬于多交叉的學科，具有知識廣且隨專業(yè)不同著重點不同的特點。我校實驗動物學教研室以超星學習通平臺為載體，理論課采取統(tǒng)一上課模式（速課+答疑+課后作業(yè)）完成各章節(jié)內(nèi)容。速課為每位教師重點發(fā)力對象，將知識點進行切割后分別錄屏，按學生專業(yè)需求進行組合上課，輔以課堂答疑進而打破師生溝通空間障礙。學生靈活點播錄屏，能有效錯開網(wǎng)絡(luò)高峰從而避免焦躁心理。同時，方便重點學習或反復學習。實驗課基本操作部分采取現(xiàn)有資源視頻展示，部分需要拓展的個別實驗課程申請返校后線下完成?？傮w來說，這種簡化的上課模式師生均能很快接受并進入上課狀態(tài)，教學效果良好，值得進一步推進與完善。

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）疫情以來，面對疫情防控的嚴峻形勢，全國各省、市、自治區(qū)等相繼啟動公共衛(wèi)生I級響應(yīng)制度[1]，各地實行嚴格交通管制，同時全國高校開學時間也不斷推遲[2]，大量返鄉(xiāng)大學生滯留家鄉(xiāng)，實行嚴格居家隔離。實驗動物學是生命科學領(lǐng)域一門新興的基礎(chǔ)性學科，它在自然科學基礎(chǔ)上綜合了醫(yī)學、動物學、胚胎學、生物遺傳學等諸多學科理論知識和研究成果，知識體系不斷交叉整合，又互相融合[3]。受新冠肺炎疫情影響，全國各級各類學校為解決延期開學階段學生的居家學習問題，紛紛組織師生開展在線教學工作。各教學單位充分利用在線教育平臺和資源，結(jié)合各種形式的教學手段做到“停課不停學”[4]。由于實驗動物學是多交叉的學科，涉及理論與實踐知識非常廣泛，而現(xiàn)有的在線資源積累相對很少。從教師層面來說，在線教學教師需要重新編排知識體系，同時還需提高網(wǎng)絡(luò)技術(shù)。從學生層面來說，在家學習缺乏學習氛圍，還可能面臨網(wǎng)絡(luò)壓力。因此，如何讓每位學生安心在家上好這門課程面臨很多的考驗。因此，本文旨在探討新冠肺炎疫情下如何應(yīng)用網(wǎng)絡(luò)在線平臺實現(xiàn)實驗動物學課程教學。
