The development of expert systems , which can provide advice and information on the basis of human experience which is fed into them, is one step in the direction of machine intelligence. However, such systems are limited to knowledge in a tightly defined domain, and cannot operate outside this area. Nevertheless, there may well be something here for education. The Computer in the Classroom
Where does this leave the computer as a tool for the teacher? Clearly teachers must exploit its strengths rather than complain about its weakness. However dull much drill and practice material may seem, children will often work at it for a considerable time without losing concentration. Rote learning is rightly out of favor in most educational contexts, but there are certain things which it is convenient to be able to recall instantly, and the computer can help us to remember them. The school pupil soon learns that the computer never gets tired, never loses its temper, will always respond almost instantaneously to any input, and does not display the pupils ignorance to other people, and these factors help to provide a micro-environment within which the pupil is stable and secure.
The introduction of computers into primary schools has concentrated the minds of educators on the use of the machine as an aid to the teacher, without the distraction of computer studies as a subject in its own right. The computer is very good at storing and rearranging information, and the introduction of simple database manipulation packages has allowed teachers to present pupils with the opportunity to collect information which is of interest to them, to structure it appropriately, and to store it on the computer. From the files thus produced various reports can be generated. These packages can be used in a variety of areas of study, from history to science, and an introduction to them is now an important part of teacher education in the use of computers. Computers can also simulate various dynamic situations, and a number of packages exploit this ability. Even the adventure games, which are sold for amusement to home computer users, can be turned to advantage if the problem-solving aspects are emphasized and the pupils activity is appropriately structured.
