Technologies such as videoconferencing will remove the need to travel to school by the year 2020, according to 2.5 million schoolchildren.
A third of the 7.5 million children asked by supermarket chain Tesco predicted that remote connectivity will replace the need to go to a physical classroom.
The survey, part of Tesco's Computers for Schools campaign, asked children to imagine their lives in 15 years' time and predict the top five changes.
Six out of 10 predicted that the morning register would be scrapped in favour of body recognition techniques such as retina scans.
School employees were also earmarked for an upgrade. Forty-two per cent of schoolchildren felt that dinner ladies would be replaced by robots, and a fifth thought that virtual bus drivers would handle any school transport.
Four out of 10 also envisioned colourful live holograms being used as a teaching aid.
"It's fantastic that children's imaginations are stimulated by technology, and its continuous development opens up a wealth of opportunities for them," said Dr David Lewis, a child development expert.
"However, we should remember that this is future gazing because going to school is about much more than simply learning from a textbook.
"Children learn to develop core social skills at school, which are integral to the formation of the people we become and help to nurture our ability to operate in today's increasingly competitive environment. So school will never really be out."
