An interactive computer simulation of experiments on guinea pig airways designed to teach the fundamental pharmacology of the airways.
This highly interactive program uses pulmonary function data obtained from guinea pig to teach the fundamental pharmacology of the airways.
1. AIMS, INTRODUCTION and METHODS sections of the program use a combination of text and high-resolution colour graphics to describe:
2. EXPERIMENTS is the main section and allows the student to select, from a menu, to study the effects of various mediators and inhibitory agents in the normal and allergen-sensitized animals.
Normal Guinea Pig:
Allergen-sensitized Guinea Pig:
For each experiment the display shows simultaneous traces of resistance, dynamic compliance and blood pressure which are presented in a form similar to that in the Mumed recording system. Each set of data is accompanied by self-assessment questions which demand interpretation of experimental data presented to them, and an understanding of the underlying control mechanisms. These student-centred activities make the program useful for self-directed learning or, in the ideal situation, it would be incorporated into a structured teaching programme and used with a teacher-designed workbook. It is envisaged that the program could be used in a number of ways: to better prepare students who will perform the practical at a later date; to debrief students after they have performed the practical; as a ‘fallback’ to provide data for students whose experiments were unsuccessful; as an alternative to the practical, though it should be remembered that different learning objectives may be achieved.
