A "Hard and Soft Tick" auto-tutorial that integrates basic knowledge of the parasite biology with practical aspects of tick identification, clinical presentation, pathology, disease transmission, treatment, and control was developed at the University of Wisconsin-Madison School of Veterinary Medicine. The purpose of this study was to assess Impact of the auto-tutorial on parasitology test scores in four classes (1999, 2000, 2001, and 2002) of veterinary students. The analysis revealed a small but significant Increase (p = 0.054) in mean percentage examination scores for students who used the tutorial over those who did not.
