Multidimensional Scaling Assessment of Medical and Veterinary Student Knowledge Organization of Pulmonary Physiology Concepts.
McGaghie, William C.; McCrimmon, Donald R.; Thompson, Jason A.; Ravitch, Michael M.; Mitchell, Gordon
This study applies multidimensional scaling (MDS) to a knowledge organization problem involving 12 concepts in pulmonary physiology. The concept structures were derived from individual medical and veterinary students before and after focused instruction. One hundred seventy medical students and 85 veterinary medical students completed a questionnaire about the similarity or relatedness of the concepts in pairs before and after instruction. Results from the study permit two general conclusions. The first is that the data pass the coherence test in that the pairwise similarity judgment data about the concepts met the scientific standards for goodness of fit. The concept organization data analyzed by MDS and concept educational achievement data contained in the final examination scores were trustworthy. However, the other conclusion is that the correspondence of the data is not established. Data suggest that knowledge assessment using structural methods like MDS produces results that are different from results obtained by knowledge assessment using multiple-choice tests. Each of these two approaches to student assessment in pulmonary physiology yields solid data, but for practical purposes, the data have no common variance. (Contains 2 tables and 24 references.)
