Abstract
The Transfusion Medicine Tutor (TMT) has been designed to study the use of computers in teaching concepts and problemsolving skills important in the field of clinical laboratory science. This system provides students with an opportunity to gain experience by solving a wide range of actual cases, and coaches these students when they are having difficulties. This system is designed specifically to detect and respond to a variety of errors that students may make while solving cases, and to suggest more advanced problem-solving methods when appropriate. This article describes the concepts behind the design of TMT. Immunohematology 1993;9:22.
