This Phase I SEPA proposal supports a consortium of science and education partners that will develop System Dynamics (SD) computer models to illustrate basic health science concepts. The consortium includes Oregon Health Sciences University (OHSU), Portland Public Schools (PPS), Saturday Academy, and the Portland VA Medical Center. SD is a computer modeling technique in which diagrams illustrate system structure and simulations illustrate system behavior. Desktop computers and commercial software packages allow SD to be applied with considerable success in K-12 education. NSF grants to Portland Public Schools have trained over 225 high school teachers in Portland and surrounding areas. Two magnet programs have been established with an emphasis on systems and at least five other schools offer significant systems curriculum. Major components of this project include (1) Annual summer research internships at OHSU for high school teachers and high school students, (2) Development of SD models relevant to each research project, (3) Ongoing interactions between high school science programs and OHSU research laboratories, (4) Development of curriculum materials to augment the use of the SD model in the high school classroom or laboratory setting, and (5) Development of video materials to support the classroom teacher. Content will focus on four fundamental models: linear input/exponential output, bi-molecular binding (association/dissociation), population dynamics, and homeostasis. Each of these models is very rich and may be extended to a broad variety of research problems. In addition these models may be combined, for example to illustrate the effect of drugs (binding model) on blood pressure (homeostasis model). System Dynamics is an exemplary tool for the development of materials consistent with National Science Education Standards. SD was specifically developed to emphasize interactions among system structure, organization, and behavior. Students use these material as part of inquiry-based science programs in which the teacher serves as a guide and facilitator rather than the primary source of all content information; technical writing by students is also encouraged. Finally, these SD materials will provide a coherent body of work to guide the ongoing professional development of the classroom science teacher.
Serial Passage: AIDS, Race, and Culture. is a 3-4 hour documentary film series and curriculum enhancement that examines the process of scientific inquiry in the development of the serial passage/contaminated needle theory of the origin of HIV/AIDS as well as the disproportionate impact of the pandemic upon Africans and African-Americans. The long term objective of the documentary film series/curriculum enhancement is to foster a heightened awareness of the need for HIV prevention among African-Americans, particularly teenagers, who are at high risk for contracting HIV, and who have often proved unresponsive to traditional HIV prevention messages. African-Americans constitute 12.1 % of the US population but account for almost 50% of the new HIV/AIDS cases. The documentary film series is being made with a small cohort of 20 inner-city African-American high school students in Pittsburgh, Pennsylvania. The students work on the documentary series as footage evaluators, apprentice filmmakers, and will ultimately be its narrative voice. They are also research subjects. An interim evaluation report showed a dramatic increase in the students' perceived knowledge of HIV/AIDS, and a substantial decrease in their reported sexual activity. A widespread and scientifically significant Phase II evaluation of this project would be conducted via pre and post anonymous surveys administered to African-American teenagers, (high school students), and matching control groups. The ABC and PBS networks have already agreed to screen the documentary series for broadcast consideration. The Phase II application proposes to 1) complete editing and postproduction of the documentary series, and 2) work with curriculum writers and an educational video distribution company on the development and dissemination of the documentary series/curriculum enhancement.
Serial Passage: AIDS, Race, and Culture is a multi-part documentary series. The Long-term goals are: 1) to produce a documentary series exploring the specific and devastating impact of H.I.V./AIDS upon Africans and African-Americans; and 2) to create a heightened understanding of the need for H.I.V. prevention among the high-risk group of young, inner-city African-Americans who've so far proved unresponsive to available public health information. Specific Aims: 1) To deconstruct the racial stigma of AIDS, and scientifically confront the conspiracy theories which are firmly linked to the disease in black America, and in Africa; and 2) to work with an inner-city high school science class, actively involving them in the making of the series. Research Design and Methods: 1) To document on film the process of scientific inquiry which led two prominent researchers to their theory on the origin of AIDS; 2) To document on film the social impact of H.I.V/AIDS upon specific African countries, including Uganda and South Africa, and upon African-American communities in the United States; 3) To periodically screen footage of the documentary for the high school class and conduct videotaped discussions between the students and the scientists throughout one academic year; and 4) To give the students a videotaped questionnaire at the beginning and end of the year designed to measure how much they learn about AIDS and its impact upon their particular community.
