Using Paper Models to Teach Basic Concepts of the Human Musculoskeletal System

Traditionally, human anatomy is taught using cadaveric human or animal specimens, however such materials are not always available or are quite costly. Alternate instructional methods can include software, models, clay models, and illustrations. Unfortunately, while cost effective, these methods lack the ability to demonstrate the "in situ" three-dimensional relationships between anatomical structures. This study examined one alternative method of instruction, the construction of threedimensional paper models, which are currently limited in availability, and mostly designed for teaching medical anatomy programs. This study set out to determine (1) if a paper model system could be used to highlight the anatomic complexity of specific anatomic regions, (2) if a model system primarily designed for medical anatomy programs could be customized to topics and made appropriate for undergradute anatomy courses, and (3) if this low-technology and inexpensive form of instruction is an effective tool in teaching musculoskeletal anatomy. Students were given a series of four models to assemble during a time period of 4-weeks. Students were assessed with a series of paired questions before and after the model exercise relating to: number of muscles, plane of muscle, depth of structure, name and function of muscle. Comparison of the pre and post-test data demonstrated a gain in knowledge. Thus, the utilization of paper models are a viable and cost effective pedagogical tool for undergraduate anatomical education.
