Most parents and teachers would get angry when they hear that teenagers listen to their iPods while preparing for exams. But pupils who listen to music when doing their homework may be, in fact, working hard. Thirty three schools have downloaded specially written pop and rock songs for their 10,000 pupils who are studying for GCSE  . The professionally recorded music, based on texts in English literature, teaches teenagers about themes in the GCSE curriculum  . Two young men set up "Revise", the company that produced the songs, and worked with teachers to make sure the lyrics   reflected the curriculum. Some of the songs were written by Geraint Brown, a director, and they are performed by professional singers and musicians. Songs for the GCSE science and maths lessons are also being developed in 36 schools. They have also started using the program, called, "LearnThruMusic". Dave Matthews, the head of Hawthorn High School in the South Wales valleys, said the program aimed at helping teenagers who are unwilling to study. He said, "There are lots of pupils who don't have a high level of home support. It's almost cool to say you have no need to find a support and we have got to change that. With this, they don't have to be sitting at their desk at home. They can be outside, walking around or even listening to it on the bus, which is very convenient for them." Everyone has a phone, MP3 or CD player, and they're more likely to listen to these than pick up a book. "I think everyone would agree that music had an important influence on us when growing up. Both boys and girls are very good at remembering the words and dancing to the music in the charts. There's no one thing that will successfully engage (...) every child, and some of them will make little or no use of this. But the fact that they don't have to do any extra work makes this a very good deal for a kid," Dave Matthews added. The pop and rock songs used in 36 schools   _  .
