In this chapter we explore how people build new theories in the context of collaborative scientific thinking. As illustrated by many of the chapters in this volume, our default notion of "scientific thinking" has changed from that of the lone scientist or student toiling away on a magnum opus or in the laboratory, to that of people working as part of collaborative groups who negotiate goals for the task, co-construct knowledge, and benefit from the diverse prior knowledge that each collaborator brings to the table. In some ways, conceptualizing scientific thinking as fundamentally
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.
BioTrac will expand opportunities in biomedicine for low-income, first-generation college-bound high school students, increasing the number interested in, and prepared to enter, the biomedical research pipeline. Specific objectives are to: (1) Raise awareness of careers in biomedicine and provide students with real-world biomedical research experiences; (2) Increase awareness of requirements and opportunities for related post-secondary study; (3) Increase public understanding of the importance and diversity of biomedical research; and (4) Disseminate project outcomes. In collaboration with the University of Miami (UM) and Miami-Dade County Public Schools (M-DCPS), the Museum will design and implement a replicable model program exposing students to research on selected priority areas outlined in the Public Health Service's Healthy People 2000 agenda. The program will focus on areas with significant local research capacity, ties to local growth industries, and relevance to Miami-Dade's diverse communities. Students will investigate each area through hands-on lab activities, on-line research, site visits to research facilities, and through interactions with research scientists at UM's nationally renowned Jackson Memorial Medical Complex. Students will work in teams to conduct community-focused research on aspects of each priority area, using technology skills acquired as part of the program to document their research through digital video, PowerPoint presentations, and development of a BioTrac website. Students will present their research at annual symposia held at the Museum. They will also serve as science explainers in the Museum's galleries, interpreting biomedical-related exhibits to the general public. During the summer before 12th grade, students will attend residential programs at University of Florida and Florida A&M University, gaining exposure to post-secondary programs leading to careers in biomedical research. Students in 11th and 12th grade will also be encouraged to participate in M-DCPS's Advanced Academic Internship Program, gaining up to three honors credits for work in institutions engaged in biomedical research. Following 12th grade, prior to beginning college, students will be placed in an eight-week summer internships at UM labs engaged in a broad spectrum of biomedical research. The Museum will disseminate students' research experiences and project findings through an BioTrac web page, ASTC and Upward Bound conferences and networks, and Museum and UM publications.
