一、问题的提出虽然初中物理讲过继电器的知识,但学生对继电器的实际应用却了解很少。为此,在教学实践中,我引导学生用继电器制作了一种趣味防盗器。该防盗器可用于车库、仓库及家中防盗。它寓知识性、趣味性、实用性于一体,大大激发了学生学好物理和发明创造的积极性。
First, the question raised Although junior high school physics has spoken relay knowledge, but the student actually knows very little to the actual application of the relay. For this reason, in the teaching practice, I led students to use relays to make an interesting anti-theft device. The alarm can be used in garages, warehouses and home security. It integrates knowledge, interest and practicality, which greatly stimulates students’ enthusiasm for learning physics and invention.
