A program shell for the construction of computer-aided learning programs on the BBC microcomputer

Abstract

Computer-aided learning (CAL) techniques are now used at many levels of biological education. Many of these CAL programs are written by teachers because suitable material is unavailable. However, the amount of time required for the design and coding of a reliable CAL program can deter many teachers. Any CAL program can be split into two components: the ‘non-educational’ part, for example, program control structures, input–output routines; and the educational material. The ‘non-educational’ component can be organized into a program shell which can then be used with a wide range of biological topics. A program shell, for use on the BBC microcomputer, is described with an example of an application. The example is ‘LINKAGE’, a genetics teaching program.
