The following seven American programs of Computer Assisted Instruction in Medicine are among 20 implemented at the University of Bonn: OPHTHA and FUNDUS (programs of the tutorial mode), CARDI (presents information via three media on the clinical alterations of Mitral and Aortic Stenosis as well as Mitral and Aortal Incompetence), CARDIOPULMONARY RESUSCITATION (simulates patients with cardiac arrest and takes the students through the sequence of cardiopulmonary resuscitation techniques), ABDOMINAL PAIN and COMA (used over the Health Education Network), and CASE (Computer Aided Simulation of the clinical Encounter). These programs were evaluated by means of questionnaires or personal interviews. The results clearly indicate that students feel comfortable working with programs of the tutorial mode and that they regard them as being motivating and more efficient than traditional instruction. Furthermore there was a very favorable response to clinical simulation programs. (Author/VT)
