ABSTRACT
Back in the 1980s and 1990s, computer technology began to develop and expand quite rapidly beyond just the relative confines of the large, corporate mainframe users.This expansion, partly due to the falling cost of the technology, meant that the general public could start purchasing personal computers. The Sinclair ZX Spectrum, for example, with its 48Kb of memory was a huge commercial hit. This meant that teachers were also increasingly able to purchase the technology and use it to develop teaching resources for their students.
