摘要
针对模拟电子技术课程理论与实验脱节、教学资源受限等问题,该文探索设计一种“现场实验+网络直播”的融合式教学模式,将运算放大器典型实验与网络直播技术结合,突破时间与空间限制,实现理论讲解、实验演示与实时互动的融合教学。通过设计运放的差模、共模与大信号特性实验,增强学生对器件性能的直观认知与工程理解。教学实践显示,该模式显著提升学生参与度和知识掌握效果,具有良好应用价值,对推动实验教学改革和资源共享具有积极意义。
To address the disconnection between theory and experimentation as well as limited teaching resources in Analog Electronic Technology courses,this paper proposes an integrated teaching model that combines live experimental demonstrations with online broadcasting.By incorporating representative operational amplifier experiments into real-time live-streamed sessions,the approach overcomes time and space constraints,effectively integrating theoretical instruction,experimental operation,and interactive engagement.By designing experiments on the differential mode,common mode and large-signal characteristics of operational amplifiers,students'intuitive understanding and engineering comprehension of device performance can be enhanced.Teaching practice indicates that this model significantly improves student participation and knowledge retention.It demonstrates strong practical value and provides meaningful insight for promoting experimental teaching reform and resource sharing.
