Key for Some Common Gastrointestinal Parasites of Cattle, Sheep, and Goats

Introduction

This is a class project for HI5304 Cognitive Engineering, spring 2005, at the University of Texas School of Health Information Sciences at Houston, with the kind cooperation of Dr. Thomas Craig of the Parasitology Department of the College of Veterinary Medicine at Texas A&M University. This project applies the principles of engineering psychology (cognitive engineering) to the redesign of a veterinary parasitology identification key. The final paper for this course will be posted on this site after May 2, 2005.
