The Experiential Science Education Research Collaborative (XSci) at the University of Colorado Denver has established a museum educator/theater network of eight museums around the country, pairing larger with smaller institutions. The Association of Science-Technology Centers, the NASA Astrobiology Institute, and the Astronomical Society of the Pacific and several other organizations also are collaborators. The primary audience is informal science educators; secondary audiences are museum and science center visitors. The Science Theater Education Programming System (STEPS) is a technology the allows educators to create their own media-enhanced live theatrical presentations of science programs that include dynamic content, interactive virtual characters, and multiple plot-lines and endings to shows. The initial set of theater programs focus on astrobiology, along with a suite of training programs and communication formats for educators. The STEPS technology allows these programs to be delivered both on site and via outreach, depending on the goals of each organization. An in-depth research component is examining the impact of the project\'s designed community of practice structure utilizing team leadership theory in terms of professional identity construction for participating informal educators. Deliverables include: the museum partnership network, the STEPS system and programs, professional development tutorials and workshops, evaluation of the programs, and research products, among others.
The following comprise the CONCLUSIONS of SRA's evaluation: POLAR-PALOOZA toured the United States at a time when the topic of climate change and global warming appeared relatively low on a list of Americans' concerns (Pew Research Center for the People and the Press, 2006), with the economy, war, and health care taking precedence. Nevertheless, POLAR-PALOOZA was a powerful format for engaging the public and teachers with science, while also being a rewarding and worthwhile experience for the traveling scientists. PPZA was an ambitious and complex undertaking designed to bring what is
