This document presents a description and explanation of the MUSE module, a multimedia, computer-supported, problem-based learning (CS-PBL) unit that provides users with a simulation of the special education referral process. The module, developed by Leafstedt et al. (2000) depicts an elementary Hispanic student who is limited in English proficiency and is also experiencing academic difficulties. The module is available for viewing at http://www.caselinks.education.ucsb.edu. The simulation provides preservice teachers an opportunity to grapple with the complexity of determining the nature of academic problems (i.e., are the student's academic difficulties related to English language limitations or a disability?). The module serves as an adjunct to lectures and readings in teacher preparation courses and consists of three sequential phases: (a) narrative, (b) role strands, and (c) problem resolution.
