THE Education Department has called on teachers and students to tune in to a new English radio programme in order to get a wider exposure to the language in a relaxed manner. Mr Dominic Wong Shing-wah, the Director of Education, is urging schools to record the programme and borrow the materials for teaching in classrooms or use in extra-curricular activities. Teen Time, jointly produced by the Education Department and Radio Television Hong Kong (RTHK), is a special six-month radio programme aimed at secondary school students. Stimulating topics geared to teenagers, encompassing music, movies, gossip, fashion, lifestyle and pop culture, will be aired. A current affairs section will also be included to promote general knowledge. The programme is not only designed for young people, but also produced by them. About 40 students have already been recruited and trained to help with the programme. They will act as speakers in discussions and interviews and as callers during phone-in sections. ''The students are not only listeners, we emphasise students' active involvement,'' Mr Wong said at the launching ceremony. Mr Wong urged secondary school teachers to make use of suitable parts of the programme in their school activities. ''Not all teenagers are free to listen to the programme. Some may miss it, but it will be a good idea for principals and teachers to record the programmes and choose some useful topics to teach in class. ''They can keep the materials, borrow the contents and revise some topics to make it suitable for teaching in the classroom or use in extra-curricular activities,'' he said. In addition to getting exposure to the English language, the programme offered students a chance to get hands-on experience in the production of radio programmes, he added. Miss Cheri Chan Yu-yan, presenter and producer of the programme, hopes teenagers, through listening to, or taking part in the programme, will understand themselves more. Features focusing on teenage problems and concerns, such as underage drinking, communication with parents and how to cure pimples, will be covered. There will also be interviews with local artists, school profiles, a ''Street Fashion'' in which student reporters will be sent out to interview teenagers about their lifestyle, and a ''Dear Diary'' for young people to call or write in to express their feelings. ''Students not only will improve their communication skills but also boost their confidence in using the language and get to know more about their culture,'' she said. The programme made its debut this week. If you are interested, tune in to RTHK Radio 3 (AM 567) from 9 pm to 10 pm, Monday to Friday. Those who want to help with the programme or have ideas to contribute can call the Teen Time hotline on 339-6412.
