Educational tools like visual media,film,video and television were considered as high potential impact. They are now more accessible and less cumbersome to use.
The VCR (Video Casette Recorder) gave us flexibility. We could watch the 1st twenty mins., stop the tape and discuss elements for introduction,mood,suspense and characterization-and view it again.
Dale says the film,video and tv transmit a wide range of audio-visual materials, stiil pictures, films,objects, specimens and drama,bring models of excellence to the viewers, bring the world of reality to the home and to the classroom through a "live" broadcast or as mediated through film or videotape, Make us see and hear for ourselves world events as they happen, make some programs understandable and appealing to a wide variety of age and educational levels, become a great equalizer of educational opportunity beacause programs can be presented over national and regional networks, provide us with sounds and sights not easily available even to the viewer of a real event through long shots, close ups, zoom shots, magnification & split screen made possible by the tv camera, can give opportunity to teachers to view themselves while they teach for purposes of self-improvement, can be both instructive and enjoyable-with sight and sounds and motion, tv is much more enjoyable.
INSIGHTS AND REACTION:
The film, video and tv are powerful instructional tools. Teaching-Learning process become more concrete,lively,colorful & interactive if they are used appropriately and moderately. It adds to a more lasting learning because of its visual, audio and motion effects. These effects make learning fun and enjoyable. Moreover, misuse and abuse of these tools in the classroom and even at home has a negative effect or leads to a damaging effects in the development of learner or childrens' imaginative and thinking powers and sensitivity to human life. The most known weakness of the tv is the effect of tv violence on peoples' aggressive behavior. The effect of tv depends on how it is used. It can give a more accurate, more lively & more colorful presentation of a difficult topic in physics for example the one who teaches the topic is inexperienced & can only make use of still pictures in black and white as visual aid. There are educational benefits of the use of the tv but when used excessively, it can impair & destruct the development of children's ability to visualize, to be creative and imaginative. Never expose children on TV violence. The violence effect on media results to a bigger aggression than the effect of exposure to lead on IQ ability in children, the effect of calcium intake on bone mass, or the effect of homework on academic achievement, or the effect of asbestos ( cancer) exposure on cancer. Cause of high rate of violence is the high exposure to media violence.
Use the TV appropriately & moderately. Accompany your children in watching TV so that you can expalin clearly nor correct them when there is something negative shown on screen. Try to explain to them the advantage and disadvantage on tv and advice them what is necessarily right and avoid or evade doing the bad show; never imitate the bad ones on tv. Try to give advises to your children not to stick or glued on tv; to mind them also their assignments in school or even household chores. Never leave children esp. the most young ones alone on tv, it needs parental guidance.
