Every primary and secondary school in Britain has a computer. No other country in the world can make that boast. In March the Government is axing the Microelectronics Education Programme (MEP), its replacement, Microcomputer Support Unit, will have half the budget. This week's programme comes direct from a secondary school in Berkshire and examines the role of computers in schools. Lesley Judd asks why the Government is cutting back school software. Ian McNaught-Davis discovers how chalk and talk is giving way to bits and bytes. Fred Harris goes for a ride on a computer bus.
