An interactive computer simulation program has been developed at Northern Illinois University for use by undergraduate students majoring in special education. It was designed so that these students could learn to evaluate the exceptional student using diagnostic and remediation skills. Initially, the special education undergraduate is given only the name and age of the learner and a short statement from the teacher. The undergraduate then goes through a five stage process with the computer. Stage one involves the student deciding if there is a problem by selecting appropriate screening tests, assessing cognitive, motor, and language skills, to be administered. In stage two, screening decisions are made, based on test data, and it is determined whether further diagnostic testing is needed. In stage three, the education student, looking at the data gathered, determines the problems the exceptional student may have. Stage four involves the formulation of a diagnosis, and in stage five recommendations and referrals are made and a teaching plan developed. (JM)
