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
The impact of two science enrichment programs on the science attitudes of 330 gifted high school students was evaluated using a multimethod, multiperspective approach that provided a more comprehensive evaluation of program impact on science attitudes than did previous assessments of science programs. Although pre-post comparisons did not indicate positive impact on science attitudes, other measures provided strong evidence of program effectiveness. Program benefits were greater among girls, those who had more supportive families and teachers, and those who entered the programs with greater
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.
KY-H.E.R.O.S. (Health Education Rural Outreach Scientists) is a health science education program that partners the largest science center in Kentucky with Science Heroes-- important regional biomedical research scientists. The Science Heroes, their stories and their studies serve as inspiration to our rural audience. The project objectives are to: (1) Convey the relevance of health science research to people's daily lives and promote awareness of healthy lifestyle choices and wellness; (2) Promote understanding of the fundamental principles of the scientifc process and inspire K-12 teachers to incorporate current research into their teaching of health science; and (3) Encourage students to pursue advanced science education and increase awareness of the wide range of health science related careers. The Science Center, working with the distinguished Science Heroes, their research teams and a group of 15 knowledgeable professional advisors will develop the new KY-H.E.R.O.S. science education program. The program will include new hands-on labs and demonstrations, teacher training workshops, career exploration activities, interactive videoconferencing distance learning links, and innovative public programs. Using museum-based exhibits and a wet lab, traveling exhibit components, telelinking (distance learning), an interactive website and printed and electronic materials, we will present information about the work of the Science Heroes and its relevance to the lives of participants. The focus of the program will change every two years to feature three different scientists and their work. A total of nine scientists will be included during the 5 year period covered by the SEPA grant. As the focus changes every two years to a different three scientists, all the programs and exhibits will be changed accordingly. KY-H.E.R.O.S. will be designed to serve audiences composed of school groups on field trips; teachers in workshops; classes in remote areas of the state participatng through videoconferencing; underserved groups including economically disadvantaged, minorities and young women; and the family audience that makes up about 60% of the Science Center's annual attendance. Formative and summative evaluation will be conducted by an outside firm to ensure effectiveness.
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.
The long-term goal is to broaden our model program that currently targets African-American populations in the national capital area. The aim of the program is to: a) educate junior and senior high students and elementary school teachers directly; and b) provide opportunities for exploration of health-related sciences for the public at large (via an interactive website) so that topics in the biomedical sciences become "friendly and familiar" rather than the existing stereotype that science is erudite, obtuse, and incomprehensible. Specific objectives: (A) Design hands-on experiences in science laboratories and opportunities to interact with scientists in the setting of a sophisticated research institute; especially target under-represented minorities, students from inner city schools and other local schools where science opportunities may be limited. This will include junior and high school students, elementary school teachers, as well as interactions with Children's Museum and other similar organizations. (B) Set up interactive web-based informatics to include: i) a system where high school students could refine the question they are posing for science projects by discussing it with a professional scientist; ii) a general "ask-the-expert" site for science and health issues; iii) a reference site containing the detailed experimental protocols for student experiments; and iv) an interactive resource to aid teachers throughout the U.S. to establish contacts with scientists. The goal of this project is to extend the reach of current health science programs that are targeted to females, African-American junior and senior high school students, and elementary school teachers, located in the Washington, D.C., metropolitan area. The project includes laboratory apprenticeships, student mentoring, and an interactive website to help students and teachers establish contact with scientists nationwide.
