Dear Editor,
We represent the Young Journalists Club and we would be happy to publish some of our articles in your journal. The topics we study refer to teenagers’ life. We run different surveys and questionnaires which help understand what teenagers are interested in, what they care for, and what they are indifferent to. Most of our research is on political and cultural issues, and we want to find out how competent contemporary teenagers are in those topics. We certainly don’t ignore environmental issues and human rights problems and try to display a wide diversity of views and opinions.
Lately we’ve been studying the TV topic, i.e. what teenagers watch on TV and what TV programmes they enjoy. Forty teenagers, aged 14-16, were interviewed, and we got some curious results. Here are some of them.
About thirty-five percent of the interviewed said that they don’t watch the news at all. “I don’t watch the news,” said Julia Smith, one of the typical representatives of that group, “they speak either about wars or terrorist attacks. If I watch it, I feel down and scared …, so … I don’t watch it at all.”
Sixty-five percent watch the news occasionally and randomly, and were not able to name any programme they trust. They confuse Presidents and Prime Ministers, and they are not sure about the regions of armed conflicts, and don’t know what the word “summit” means. However, about half of our respondents mentioned that they would like to fel more confident about political issues, and that it would be useful to have some classes on political literacy in the school curriculum.
The survey revealed some unexpected things. For example, most teenagers are not really keen on thrillers and action films. They say that they prefer point-and-shoot computer games to action films.
As for TV, about sixty percent of our respondents claim that they would like to see more educational, cultural and popular science films on TV. Scientific breakthroughs, new technologies, mysteries of the past and the present, ancient civilizations are very welcome. These topics have always been a great attraction for teenagers of all generations.
In conclusion we would like to thank you for the time you gave to our letter. If you find our topics of some interest to your journal and your readers, we would be happy to present the full texts of our projects and articles, and discuss our possible cooperation.
Sincerely yours,
Martine Swift
President of the Young Journalists Club
