Goal-based scenarios (GBSs) have become a mainstay of Andersen Consulting’s 900 million dollar efforts to train its employees. Utilizing a theoretical framework based upon social constructivist theory, we create classroom learning environments that use theatrical elements to simulate real-world client engagements. The suspension of disbelief, however, is one factor that can be detrimental to human learning in immersive simulations. This paper describes one of our school designs, constructs a theoretical framework to support our approach, examines some of the factors associated with the suspension of disbelief, and makes recommendations for enhancing the authenticity of goal-based scenarios.  相似文献

This study examined the effectiveness of a comprehensive, school‐based intervention program, Creating A Safe School (CASS; The Ophelia Project) designed to reduce relational aggression (RA) and relational victimization (RV). Sixth‐grade students (N = 406) were surveyed before and after the intervention. Program effects were tested using a repeated‐measures design. Results revealed significant reductions in RA and RV among students who reported initially high levels of involvement. Findings also showed that decreasing approval of RA accounted for a significant amount of variance in changes in RA between pre‐ and posttest. These results provide initial evidence of the effectiveness of the CASS intervention model in reducing RA among early adolescents. © 2010 Wiley Periodicals, Inc.  相似文献

This is a list of books that should be available in either the hospital emergency room or the medical library. The forty-nine books listed are divided into the following categories: General, Surgery and Trauma, Burns, Cardiology, Dentistry, Disaster Medicine, First Aid, Geriatrics, Obstetrics, Pediatrics, Psychiatry, Toxicology, and Transportation. An asterisk has been placed before twelve books that are particularly recommended for the hospital emergency room as well as the medical library. The latest edition is given for each book, and, unless otherwise noted, each has been annotated by one of the authors.  相似文献

Since 1962 the members of the loosely organized Detroit Medical Library Group have carried on a slow but steady self-examination program. They found a need to increase resources and developed a periodical exchange, then a need to identify these resources and did so by means of a serials list. More recently, a similar program for texts and monograph resources was begun. Data, more particularly that of the interlibrary loan process, is being gathered to show the flow within the area and the flow from outside to further identify the existing resources. They have made contact with the administrators of the biomedical institutions and gained their backing (a) to further study the makeup of the community and (b) to formulate an administrative structure through which these institutions can act. These activities are evidence of the beginning of a strong medical library network for the Metropolitan Detroit Area.  相似文献
