explanations (slowed down or accelerated).

workbooks, instruction manuals,'-textbooks, tools, or other
objects that are usually for in the field.
e) Information that can be presented simultaneously at the same

time in different locations (classes), and with an unlimited
number of spectators or participants, by placing monitors
(television sets) in the classroom of the course.

according to their respective speeds can be designed. This
self-contained design of activities is usually equipped or

combined with the help of a computer or printed material.
