Motivating questions:
I want to project what is on my laptop to a screen in the classroom, so that my students can see what I am writing or seeing on my computer. Thus, by avoiding chalk boards and white boards, I can face my students during the entire class, and I avoid accumulating chalk dust or marker residue on my hands.
Each NOVA classroom has a built in projector, with either VGA cable or
HDMI cable, or both. However, one needs a computer with both types of
connections in order to be able to use projectors in different classrooms.
My own tablet PC does have both a VGA port and an HDMI port.
The ease of use depends on the classroom and the individual connection.
In some classrooms, the VGA cable is somewhat awkward to fasten and
unfasten. In some classrooms, one connection or the other does not work
satisfactorily. For example, in one classroom, the HDMI connection produced
an oscillating image, which was not usable.
Usually, all that is necessary is to plug in the appropriate cable.
Sometimes, I have had to instruct my tablet PC to switch to projection mode.
The projectors and connecting tables are installed in each NOVA classroom.
There is no cost to each instructor, but NOVA must supply and maintain the projectors. |
