我设计并制作了多功能自控演示器,通过教学实践,激发了学生的学习兴趣,巩固了所学的知识,提高了学生动手动脑的能力,收到了较好的教学效果.一、教具特点1.本教具可形象、直观地演示电磁继电器在实际中的远距离操纵及自动控制作用,使学生真正了解到电磁继电器的原理及应用.2.该教具将远距离控制,水位控制、温控、光控等有机地结合在一起,演示的内容多样,生动有趣.
I designed and produced a multi-functional automatic control demonstrator. Through teaching practice, I inspire students’ interest in learning, consolidate the knowledge they have learned, and improve the students’ ability to use hands-on and brains. I have received good teaching results. First, teaching aid features 1 This teaching aid can visually and intuitively demonstrate the remote control and automatic control of the electromagnetic relay in practice, so that students can truly understand the principle and application of the electromagnetic relay. 2. The teaching aid will control the distance, water level control, temperature control, Light control and other organically combined together, the content of the demonstration is varied, vivid and interesting.
