Computer Assessment Using Visual Stimuli: A Test of Dermatological Skin Disorders
One of the advantages afforded by computerized software is the ability to present on screen the photographic-like images of objects, people, or scenes. Over the past several years, testing practitioners have taken advantage of this capability and started to create computerized tests containing images embed ded within the items. The potential for the use of such images spans many dis ciplines. For example, art instructors could use computerized tests with images to test students’ ability to identify certain works or artists; instructors of dendrology could have students identify different types or parts of trees; and geology instructors could have their students classify different types of rocks or rock formations. To provide an in-depth example of such an assess ment, this chapter focuses on a computerized test that was developed in the medical field of dermatology. It was a joint effort between the University of Il linois Educational Psychology Department and the Medical College of Wis consin Dermatology Department. To date, the development of the test has spanned more than 2 years.
