Development of a Computer-Adapted Form of the Scientific Literacy Test

The purpose of this study is to computer-adapt the Scientific Literacy Test. The challenges in doing so were: (1) developing a programming procedure that would make it possible to present complex graphics on an Apple lIe while administering the computerized Scientific Literacy Test, (2) designing equivalent graphic test-items, and (3) developing a program that a majority of students favor. Factors that may affect student performance on computer-administered tests are reviewed, the program developed to present complex graphics is listed, assessment of test-item equivalency and student attitude are discussed, and suggestions regarding further development of the product are proposed
