TELEVISIONS There are lots of ways to watch television and our
purpose for viewing has a significant impact on what we take away
from the experience. Most TV viewing is for entertainment and
relaxation, and that's fine unless we want people to remember what
they've seen. Television can be a powerful educational tool, but it
we want our students to absorb specific content from what they see,
we need to give them a model for viewing that is active and
critical. One of televisions most obvious characteristics is its
visual aspect. Humans instinctively grasp the power of images to
express meaning, as can be seen in the old adage that values a
picture at a thousand times the value of a word. Research in the
past two decades has proven what we intuitively know: our brains
deal with images differently than print (Saltrick, Honey &
Pasnik, 2004, p.6 ). Enhances student comprehension and discussion

THE OVERHEAD PROJECTOR Audio visual equipment has been a part
of classroom learning for decades. As an integral teaching aid,
using audio visual equipment, such as an overhead projector allows
teachers to demonstrate and present their materials to a large
audience. For those students who are visual learners, or for deaf
or hard-of-hearing students, an overhead projector is invaluable.
The overhead projector can be used according to Lever-Duffy &
McDonald (2011) along with transparencies (p.296). These visuals
are created and sold in booklets or sets and are sometimes offered
as supplements to a textbook. The advantages of using these
transparencies are that they are high-quality, ready-to-use visuals
designed for overhead projection. A transparency also offers the
teacher to maintain eye contact with their students, longevity of
visual images, and easy-to-create and easy-to- use options for
educators. The challenge of using an overhead projector for
instruction is that a bulb might burn out on your projector or it
might be blurry or hard to focus.

DIGITAL VIDEO DISC Video discs offer advantages over videotape
DVDs can store video that can be directly accessed at any point in
the video Frames can be played back as motion video or frame by
frame. DVD recorders and playback units are quickly becoming the
preferred video equipment for the classroom (Lever-Duffy &
McDonald, 2011, p. 303)

SUMMARY Audio-visual aids in the classroom can enhance teaching
methods and improve student comprehension. Today's technology
offers many choices to the informed educator who wishes to
capitalize on a new generation's appetite for multimedia
presentations (Byke, 2010, para.4). Lesson plans that incorporate
the use of audio-visual aids should be consistent with curriculum
objectives and not applied improperly. Audio-visual technology has
an important role to play in the modern classroom, but teachers who
rely too much on technology may actually inhibit learning. It's the
law of diminishing returns: you can only get so much useful
enjoyment and assistance from a machine. The personal relationship
between a teacher and a student, in most cases, can ultimately be
more valuable and rewarding in a classroom environment.
