There are some modern ways to enlarge your educational background, such as using computer programs or watching tv. Some people condider watching tv as a good educational tool. Others have just the opposite point of view. There are some causes for each thought, and every person decides by himselves if there is a sense to use watching tv in educational goals or not.
I can admit some purposes to consider the above mentioned way of spending the time useful for the education. If people want to perfect their second language it gives them the opportunity to master their listening skills, gives a look on real speech, accents and intonation. Subtitling helps you to enlarge your vocabulary, improves spelling. Watching scientific proprammes, such as national geographic, popular mechanics, leads to the understanding the "physics" of the world, its specific features. If your ability to concentrate on the subject is high there is a great chance to succeed.
On the other hand, watching tv can not be considered as an efficient educational means due to several reasons. At first, there is a problem of informational source. Only several tv resources prove their scientific relevance. For instance, you can check some facts, whivh have just been described in a tv show in the encyclopedia, to be sure that this cycle of videos uses scientific methods in their research. Secondly, I believe that there is some simplicity in description of the comlpicate processes happening around the world, in order to be easily understood by ordinary people or be in "tv format". So, using "easy language" is unscientific.
All in all, in my opinion, the result of using television in educational purposes depends on somebody's ability to focus on the subject. I also think that reasonable choice of tv programmes can give a good chance to enlarge one's educational experience.
In conclusion, I am persuaded that modern development of educational tools gives us a wide range of means to succeed. Sometimes there is a sense to use watching tv, sometimes you have to use something more traditional like encyclopedia, text book or just teacher's lectures. But everyone should try to be sure that he/she catches all of the opportunities.
