Computer aided teaching

In order to examine some of the problems and benefits of using a microcomputer as a classroom teaching aid, we observed 174 school lessons during which 17 teachers employed a microcomputer regularly with a chosen class for a whole term. It is argued that the ergonomic factors here differ considerably from those in other man/machine interactions. Problems of screen visibility were frequently noted and the inexperience of pupil and teacher operators caused a number of difficulties. Styles of computer use were very varied and these are discussed. Although educational performance was not measured by means of test scores, the range and quality of pupil activities suggests that the educational benefits are considerable. Recommendations are made to teachers, education authorities, software designers and hardware manufacturers.
