The influence of laboratoy experimental work on concept acquisition in a medical physiology course with implications for curriculum deliberations and instructional design

Abstract

Following revision of the curriculum the effectiveness of a traditional cookbook experiment, used in conjunction with an ‘interpretation seminar’, was evaluated. Curriculum revision had been predominantly concerned with an avoidance of overloading and provision of self-study periods. The preceding lectures were integrated with the experiment. The learning resulting from the practical experience was assessed using pre- and post-tests. The practical exercise was ineffective and did not facilitate conceptual understanding. Due to the central role of passive teaching methods the students adopted a surface approach to all learning, were teacher dependent and did not make effective use of their private study. Furthermore, owing to a broad-based entry into medical school many students lacked the basic skills essential to the achievement of meaningful learning. Clearly, for effective learning the curriculum and pedagogy must be geared to the background and educational needs of the students.
