The advantage or disadvantage of any invention revolves around the purpose it intends to serve.
Projectors in classroom settings for teaching
Here, we have it specified, so it is time to focus on what the educational institutional authorities have to say about a projector in classroom settings.
What do the school authorities have to say about it?
The school authorities think that projectors create an adverse climate and that establishing projectors in each classroom would be costly.
The environment makes a huge difference when installing a projector.
For projectors to project a sharper and brighter image, it needs to be installed and used in a good environment.
What is the ideal environment?
A dark or 100% light-controlled room is required; a classroom might not be a favorable environment. The students would not be able to read or take notes.
They cost you a lot.
Projectors are not only expensive to get, but they are also just as expensive to preserve as well.
The maintenance costs are another plus factor to consider.
First, you would burn a hole in the pocket and get one projector for each room, and installation and maintenance costs would be any other plus.
It consumes more electricity than the HDTV.
The said electronic device even consumes more electricity than the HDTV. Therefore, having a projector in each classroom would increase the electricity charges.
The students won’t concentrate.
Why?
To give a lecture on a projector, the lights of the classroom have to be turned off. The non-serious students would take it as an opportunity to get distracted. They would not be able to concentrate on the lecture and will keep disturbing the other students.
External speakers might be needed as well.
To sprinkle salt in the wounds, you might have to add external speakers. Even if you bring a Bluetooth speaker to connect, there would still be a mess.
They will produce noise.
Most projectors are rackety. Even if we take steps to make the projector quiet, they would still make noise. Therefore, if the classroom is noisy, the students won’t be able to hear the professor.
That is all for the disadvantages of a projector in teaching. Because the focus was solely on the negative part, I did not share the pros. Hopefully, you found whatever answer you were looking for in the shared info in this article. I will leave it to you to decide if a projector suits your purpose while teaching.
