The very fast changes and developments in technology are regular news items. Our children are growing up in a world that is more
grounded in technology than ever before.
Children nowadays don't recognize the technology their parents grew up with. There are videos and articles that show children trying to use outdated technology. It's funny to watch them try to work out what to do with a telephone that does not have a touch screen and watch the video about children trying to work out what to do with a cassette tape and a Walkman. The machines once familiar to parents are now very strange to their kids.
Who can remember when black - and - white television became colour television? One parent posted on social media that she was watching a rerun (重新播放) of a show popular in the 1950s with her young son. He asked her what was wrong with the television because the show had been filmed in black and white. He had never seen anything on television in black and white.
Television channels now broadcast 24 hours a day. In the past, television programmes had a start and finish time. After the last programme, the test pattern appeared on the screen. It showed that the transmitter (发射机) was working but that no programme was being broadcast. These patterns were also used when there was a problem with the broadcasting. Can you imagine what children would do now if they saw this kind of symbol on the screen in front of them?
To show children the technology that their parents once used, but that children don't understand is the focus of the travelling exhibit the National History Museum has put together. It features items that are now just a memory for the older generation. Go and see the exhibition now!
