In the early years of television, educational specialists believed that it would be very usefulin teaching and learning. Many schools have bought television sets, intending to use themeffectively to improve the quality of education; but actually they are not used properly inclassrooms. Meanwhile, children spending the majority of their out- of school hours watchingTV and their typical school days proceed as if television did not exist. There are someexplanations for the failure of television to get the interest of the teachers. Firstly, the schoolsthat purchased television sets have not set aside money for equipment repairs and maintenance sothese television sets are sooner and later out of work. Secondly, these schools have not found aneffective way to train teachers to integrate television into their ongoing instructional programs.Lastly, most teachers do not regard the quality of television and its usefulness in the classroom.Teachers at the schools work hard for at least twelve years to train their students to become goodreaders. However, according a recent statistics, teenagers seldom spend their free time readingbooks and newspapers but watching television instead.
