This paper describes a case study/client scenario approach used in an advanced medical/surgical nursing course; its methods of interactive learning are facilitated by the computer technology available in a "master classroom." This approach incorporates concepts of adult learning theory and creativity and group interaction. The equipment, such as an instructor multimedia computer, student computer stations, networking capabilities and a ceiling-mounted multi-source projector, is key to the implementation of the case study/client scenario approach. Four examples are provided that demonstrate variations of the case study/client scenario approach. Benefits of technology use in a case study approach to learning are discussed, including: (1) active learning and student interaction; (2) critical thinking; (3) an extension of available clinical situations; (4) practical experience in computer use and group presentation; and (5) facilitation of group interaction. Appendices offer excerpts from case information for the four examples. (Author/AEF)
