The
classroom projectors have come at a moment that is required to make it easier
for the students to learn easily and interact appropriately with technology.
Though the projectors are great for classrooms, there are some of the
challenges that the teachers face in the classroom with the projectors that we
are going to look at here and see some of the solutions to those problems. Here
are some of the challenges that the classroom projectors have.
Resolution
For
classroom projectors resolution is very important as the class or lecture hall
need to be spacious enough, and therefore the resolution of the projector needs
to be tremendous and explicit to support the large crowd in the room. Sometimes
the resolutions of the projectors are not suitable to give the best graphics to
the students and therefore making it hard for them to see and are distracted as
they cannot view the slides properly. That’s why it’s good to look for a
projector that is specific for classrooms and has excellent resolution also
works well in a large room.
Bulb replacement
Another
challenge that the classroom projectors come with is the cost of the bulb
replacement. This is a challenge as you find the projector to have a short lamp
life as the projector is used most of the time.
When the projector elapses its lamp life, you have to get a replacement
bulb to continue using, and therefore you find it to be expensive especially
the overhead projectors. An example of the cost of an overhead projector is
around $300.
Portability
When
you are working with projectors for the classroom, you have to get a projector
that is portable and lightweight to enable you to walk with it from one point
to another. Since most of the projectors used for classroom purposes are heavy
and bulky, it is not easy to work with them since they are hard to carry around
while in movement and disconnection and connection each time you want to use in
the classroom. A good example again of a classroom projector is an overhead
projector
Sound
Sometimes
the projector used in s classroom does not produce enough sound for everyone in
the room and therefore requires one to get an external sound system to make it
possible to hear effectively. We can say that this is a big challenge to most teachers
and lecturers as they have to meet and the extra cost of getting an external
sound system to enable the students to learn effectively especially when the
content entails videos and audio for study.
Power supply
This
may not be a challenge for some people, but it is a great challenge as for a
projector to work well in a room there has to be a power socket in the room to
be so. Since some of the studies may be done outdoors, the projector needs to
have a power supply at the outdoor connectivity.
Brightness
Another
challenge is the brightness of the projector. This is very important as the
brightness is very important for the displaying of the images and slide into
the classroom as without proper brightness the images may seem faded and do not
show properly.
