Medical illustrators produce vast numbers of images used in audiovisual programmes for medical teaching. We know that students can learn by using audiovisual teaching materials but do not always know how well they learn, particularly in comparison with other teaching methods. To find out how effective audiovisual teaching is, it must be evaluated or measured. This paper looks at the evaluation of a range of medical audiovisual teaching programmes and their effectiveness by observation, questionnaire, tests and examinations.
A device called the Dex Frame has recently been marketed as an aid for children with specific learning difficulties. Using a test of reading speed and a test of reading accuracy we have attempted to evaluate the device. Two groups of children with learning difficulties were used, one having sole use of the device and being allowed to carry it with them and a second group who only used the device when attending for remedial tuition and assessment. The results show that no significant improvement occurred in reading performance of the groups with learning difficulties using the Dex Frame as compared with a control group. The teachers of the groups did, however, feel that on an individual basis some children (< 10%) expressed that they felt more comfortable using the device.
