Ted's teaching tips;Parting Shots
Digital television offers thousands of channels. How does it work? Firstly, digital breaks the signal down into 0 and 1, binary numbers, so there is no loss of quality. Secondly, fine fibre optic strands carry billions of signals; every person on the planet could have a personal channel in a six billion channel cable thinner than a human hair, the so called "Superhighway". Computer and television fuse into one.
Children watch on average 25 hours television a week, roughly the time spent in school. Will more channels be a dream or a nightmare? Will people become lazy spectators? Or will they learn more? What about interactive media, where you can contribute (for instance, make local television or take part in phone-ins) or use (download pictures and sound)?
Construct a questionnaire about television: what and how much do you watch; what might you watch in future? Analyse and display the results (pie chart, histogram). Are there significant differences between boys and girls, now and the future, types of programme preferred?
