B.F. Skinner developed teaching machines that allowed students to progress through educational material at their own pace. Educational television used dedicated channels and individual programs to deliver distance education across the country to over 50 channels. Photocopiers use xerography to quickly and cheaply make paper copies of documents and images using electrostatic charges on a light-sensitive surface. A computer mouse is an input device often used with personal computers to move an on-screen cursor and select or move items by clicking buttons while sliding the mouse across a flat surface.

8. PHOTOCOPIER

9. A photocopier (also known
as a copier or copy
machine) is a machine that
makes paper copies of
documents and other visual
images quickly and
cheaply. Most current
photocopiers use a
technology
called xerography dry
process that uses
electrostatic charges on a
light-sensitive
photoreceptor to first
attract and then transfer

12. A computer mouse is an
input device that is most
often used with
a personal computer.
Moving a mouse along a
flat surface can move the
on-screen cursor to
different items on
the screen. Items can be
moved or selected by
