Impact of Video: Society
TV…illustrates the mixed blessings of
technological change in American
Society. It is a (fairly) new medium,
promising extra- ordinary benefits:
great educational potential, a
broadening of experience…
But it teaches children the uses of
violence, offers material consumption
as the answer to life’s problems…
and undermines family interaction
and other forms of learning such as
play and reading.
(Kenneth Keniston, professor, human
development: Carnegie Council on Children)
Impact of Video: Schools
Video from the community
Learning tapes from libraries
Digital video from computer nets
Local production
learning video techniques and equipment
school news, fashions and sports
‘behaving in the lunchroom at DRHS’
Common Impact Topics
Since the onset of broadcast TV, video
has has a tremendous impact on society:
Our leisure time pursuits
Where we gather knowledge and “facts”
Reports on current events
How we view each other and other societies
Race, violence, sex, clothing, food
“In 1961 I worried that my children would not benefit from TV;
but in 1991 I worry that my grandchildren will actually be harmed by it!”
(Truman: www2.truman.edu/)
I have no expectations;
but I do have hope! (Illych)
Even in the late ’50’s analysts were
warning us of potential damage to
society if TV did not “clean up its’ act…
Famous newsman and journalist
Edward R. Murrow warned television
executives that change was needed by
stating: “decadence, escapism, and
insulation from the world of realities in which we
live. And, without courage and vision, TV is nothing
more than lights and wires in a box!”
CBS
Society and Video/TV
Our leisure time pursuits
couch potatoes
home videos of storms, family histories
Reports on current events
School News to CNN
How we view each other
videos of Osama Bin Laden, lifestyles of rich
Race, violence, sex, clothing, food
Blacks on TV/Relationships/school news
Pervasiveness of Video:3
Video is entwined in almost everything we do
today. Not only do we have major video store
chains, but even our grocery stores will now rent
videos.
Vans and travel trailers have video sets
Almost every classroom has access to units
Videos have replace film in most classes
Digital Video is getting more popular
Personal camcorder recordings make the news
from weddings to war, it is not just the journalists
Issues of Concern
Is Video (TV) helping or hurting education
helping: new places and ideas
hurting: lots of garbage and stereotyping
Are we using video properly in schools
commercial versus school videos
tie-ins with curriculum
Video as both a tool and as a subject
planning and producing skills
or just playing with video and computers
Video in the Classroom: a WINNER!
The research on proper use of video
in the classroom is overwhelming
positive.
the planning process is valuable

read all sections on
video in classrooms.
visual literacy skills developed
team building and learning to provide
assigned skills
self-confidence and satisfaction from a
completed project

An Important Assumption:
These positive gains possible by using video
in the classroom are all built on the
assumption of “you get what you pay for”
(quality planning=successful video process)
A simple Instructional Design process is followed
Video tied to curriculum and student needs
Teacher as “lesson planner & guide on the side”
Some VERY basic rules of production used
Evaluation (formative and summative) planned
Content and Curriculum
