There is so much advantages of technology. If you have good technology in your classroom, let's say projector,laptop, the teacher can teach his students more efficiently, unlike writing in the chalkboard that will take hours. And technology provides better visual aids, unlike drawing it in the board.
I can't think of any disadvantages, though. But I think, these technologies sometimes break down unexpectedly, or hard to set up and consumes much electricity.So i agree that technology has a better advantage.( CindyKoo )
