The development and testing of a multiple-choice programme to teach systematic fault finding in electronic equipment

Abstract

The development and testing of a multiple-choice programme to teach systematic fault finding in electronic equipment. Fault finding and the repair of faults, in electronic equipment used by the Royal Navy, are presenting problems which have become more and 1nore difficult in recent years. This is due to two main factors; the first being that the increasing, complexity of equipment is producing a requirement for higher levels of training, and the second factor being the difficulties surrounding the recruiting and retention of men with high levels of education and training. Maintaining equipment in a ship at sea also presents special problems due to the measure of self-reliance which is necessitated by the ship being away from home ports for long periods. In an attempt to overcome these problems, an investigation was commissioned to examine new methods of fault finding. The aim was to discover a new generalised method of fault finding which could be applied to all electrical and electronic equipments, and to devise a training course which would instruct men in this new method, if it improved performance. Such a method was found, and on testing was discovered to work extremely well. Having found the method, investigation then took place as to the best way to disseminating this information. In order that training in the new method could take place in the field, without the necessity of bringing men back to training establishments, a teaching programme of the multiple choice style was written covering the fault finding method. This thesis covers the development and testing of the method of fault finding chosen, and the rigorous development and testing of the teaching programme. Both the method of finding, and the testing programme, have been accepted as standard for the electrical branch of the Royal Navy, the acceptance being based on the successful outcome of the investigation.
