实验诊断学是当今发展最为迅速的医学应用学科之一，随着内容的不断丰富及其作用在诊断中的增强，越来越成为各类医学专业学生的必修课程。因为该学科兼具理论知识点众多和应用技术方法学繁多的显著特性，传统教学模式已经开始受到挑战。尤其这次疫情背景下要求采取全网课模式，更增添了课程的教学难度。为此，本文就此次课前的精心备课、互评；课中的师生联网互动；课后的作业点评以及见习期视频的录制等关键节点所采取措施进行了回顾和总结，希望全网课模式不仅可以实现“停课不停教”的目的，而且可以实现教学计划和教学效果的双保证，为拓展实验诊断学网课教学提供经验。“,”Laboratory diagnostics is a booming medical applied subjects. With the continuous enrichment of the content and the enhancement of its role in diagnosis, it has increasingly become a compulsory course for all medical students. Because the subject has many individual theoretical disciplines and application technologies, the traditional on-site teaching mode has been greatly challenged. Especially under the background of the pandemic, it is more difficult for the teaching by the online course totally. For this reason, the measures of key sessions,such as through preparation and peer review before the class, online question and answer between teachers and students, reviewing homework after the class and recording video for probation purpose were summarized and reviewed. The online course mode was supposed to realize “non-stop teaching during pandemic”, but also realize the double guarantee of teaching plan and teaching effect, which provide experience for expanding the whole network course of laboratory diagnostics.
