本文介绍了实物直观、演示直观、模象直观三种直观教学法在电子技术课教学中的具体运用。

The paper presents an introduction to the practical application of the3 audio-visual object teaching methods ( material object , demonstration and analogue image ) for technical courses .

实物模拟器直观性强，操作逼真，但是扩展性差，造价很高，只能执行单人单次任务；而二维界面虽然造价低廉，但直观性较差，拟真度较低。

Physical simulator intuitive and strong , realistic operation , but poor scalability , high cost , and can only perform a single task of the single ; Although the two-dimensional interface low cost , but less intuitive , low degree of verisimilitude .

要建立全新的形象化教学系统，创造一个既有实践又有实物教学的直观教学环境。

New visualized teaching system should be built and thus can create a clear teaching environment with practice and real materials .
