Design principles for problem-driven learning laboratories in biomedical engineering education.

This article presents a translational model of curricular design in which findings from investigating learning in university BME research laboratories (in vivo sites) are translated into design principles for educational laboratories (in vitro sites). Using these principles, an undergraduate systems physiology lab class was redesigned and then evaluated in a comparative study. Learning outcomes in a control section that utilized a technique-driven approach were compared to those found in an experimental class that embraced a problem-driven approach. Students in the experimental section demonstrated increased learning gains even when they were tasked with solving complex, ill structured problems on the bench top. The findings suggest the need for the development of new, more authentic models of learning that better approximate practices from industry and academia.

Uncertain science and certain deadlines: CDC responses to the media during the anthrax attacks of 2001.

This paper presents a study in which communication personnel for the U.S. Centers for Disease Control and Prevention (CDC) provided first-hand accounts of the experience of responding to media inquiries during the 2001 anthrax attacks. In-depth interviews were conducted with 19 communication professionals who worked either at the CDC headquarters in Atlanta or at field locations in the U.S. where persons were exposed to anthrax. The interviews sought CDC staff viewpoints on how the CDC handled a historically unprecedented level of press activity in terms of work locations and equipment, information flow and clearance, and staff roles. Staff reported that the situation led to new work practices, tools for performing the work, and an enhanced understanding of what it takes to be prepared for and to handle communication work during a terrorism-related health crisis. The paper provides a discussion of implications of the findings for CDC and for other public health organizations developing systems for communication response during health-related crises.
