To design and test the effectiveness of computer based learning in supporting teaching and promoting student learning in microanatomy

Abstract

The 1990's have brought some critical challenges to medical and dental students. The amount of information necessary to function effectively in the medical profession is expanding. This knowledge explosion results in curriculum crowding, making it more difficult for students to master the curriculum. The problems encountered when studying the course are retention, understanding and application of basic science information. The dentistry students at the University of the Western Cape encountered several problems studying the histology course, viz. the short time allocated to assimilate an immense amount of knowledge, integrating theory (the lectures) with the practicals (microscopy) and the orientation and identification of sections on microscopic slides. A series of revision programs were designed in histology using a Macromedia Authorware program. Each program has a set of light micrographs with relevant text. Images are labeled to orientate and help students to identify the sections. These programs are incorporated into the curriculum to assist students in the mastery of important concepts in microanatomy. A test was added to the program, which allowed students to assess if they had mastered the chapter(s) they were revising. Students were given time to use these programs, alone or in groups, for as long as they needed and as often as they wanted to use them. They were also given questionnaires in which they were asked to evaluate the programs as well as the testware. The results showed that they enjoyed using this innovative means of studying. They felt the computer based instructional programs definitely enhanced the course. Multimedia tutorials also created an environment that encouraged peer learning and peer teaching. Being able to assess their knowledge once they had completed the chapter was not as traumatic as a class test. In its initial stages, these programs have shown to be an effective tool for the learning and self-testing of histology. It is clear from the results that students found this an interesting way to learn histology.
