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.
The Internet, specifically the World Wide Web (WWW), has the potential to deliver science education materials directly to classrooms, media centers, libraries and homes. The current application seeks to use this new technology through a collaborative effort of an active scientist and a group of middle school science teachers to develop, disseminate and evaluate educational materials related to neuroscience for use in middle school science classes. This project attempts to introduce new technologies into the science classroom, extend science education to include the information superhighway and increase parental involvement in their children's education. Materials will be integrated with the existing middle school science curriculum and will include l) on-line and off-line experiments and activities covering a range of topics in neuroscience, 2) a "virtal neuroscience laboratory", 3) an Internet neuroscience resource list and 4) a "Neuroscientist Network" consisting of active neuroscientists around the world who will serve as experts answering student questions. All activities will be designed will attention to being self-paced, hands-on, entertaining and to involve Cooperative learning. Both quantitative and qualitative methods will be used to evaluate the usage of the Intemet Neuroscience Resource. It is hoped that this project will serve as a model to other scientists and teachers and to encourage them to develop Internet resources in their own areas of expertise for use in the classroom.
