The government offer of half-price computers led to the installation of a large number of school microcomputer systems at a time when there was very little educational software. At the same time there was an explosive demand for introductory courses, at first for secondary teachers and later, when the offer was extended to primary schools, for primary teachers. It would be impossible, and inappropriate, to make every teacher into a computer programming expert.
