【摘要】利用互联网进行线上教学的模式突破了传统线下面对面教学在特殊时期难以实现的瓶颈，借助互联网还可以充分利用各种资源以丰富授课内容和形式，具有明显的优越性。然而，进行线上教学时教师通常不能及时有效地掌控课堂，教学质量难以保证。本文基于腾讯会议软件平台，以《传感器与信号调理》课程为例，针对线上教学所存在的问题，结合该课程线上教学的实践，分别从课前、课中和课后的整个教学过程，探讨了提高线上教学质量的方法，构建了一种基于线上直播、线上线下相结合的教学模式。实践表明，采用该模式，拓展了教学的时间和空间，充分调动了学生自主学习的热情，培养了学生主动思考和进行创新的能力，取得了良好效果。

【Abstract】The mode of using the Internet to carry out online teaching breaks through the bottleneck that traditional face-to-face teaching is difficult to achieve especially during a special period， and can make full use of various resources to enrich the content and forms of teaching， which has obvious advantages. However， the advantages and disadvantages of online teaching coexist. Teachers usually cannot control the classroom in time and effectively， and the quality of teaching is difficult to guarantee. Based on the Tencent conference software platform， taking the “Sensors and Signal Conditioning” course as an example， this paper explored ways to improve the quality of online teaching from the entire teaching process before， during and after class， and constructed a teaching model based on online live broadcast and a combination of online and offline. Practice has shown that the adoption of this model has fully stimulated students enthusiasm for self?learning， cultivated students ability to actively think and innovate， and achieved good results.
