Gone are the days when teachers were using traditional accessories in schools. The New Laser Diode Technology
has changed the mode of teaching today. Despite of using the wooden
teaching sticks, teachers these days are using laser pointers to
pointing out the context over the whiteboard.
The
best advantage of using laser pointer is - you do not need to stand in a
particular place (close to the white board) to denote something on the
screen. You can move to anywhere in the classroom and can specify your
points and subsequently can draw student’s attention to the whiteboard
with the help of a laser pointer.
The
pointers that are being used by many teachers in schools and
professionals while giving presentations are nothing but the devices
that produce radiations. In other world you can say, these devices emit
lights (i.e. red light) that point straight, which is what helps
teachers to use that device to pointing out any particular context on
the screen from anywhere in the classroom without standing at the same
place from starting to end during the period.
