Beginning on page 9, Jack D. Thatcher, PhD, describes the results of a study in which 22 students who had been admitted to West Virginia School of Osteopathic Medicine in Lewisburg but who had not yet begun classes were asked to complete a prelesson test, a lesson, and a postlesson test. The lesson explained the process of deoxyribonucleic acid replication using either a computer animation (n=12) or a chapter from a textbook (n=10). Lesson comprehension as measured by the tests was significantly higher for students who used the computer animation than for students who used a textbook chapter (P<.01).
