Reports from the NSF, NRC, AAAS, and others urge over and over that we must teach "science as science is done," that "science is a way of knowing," that our goal should be to impart "scientific habits of mind," and that learning must be learner-centered and oriented toward process. Fine. But what does this really mean for science education, and especially laboratory education?
The purpose of this paper is to examine the role of laboratory-based science from a perspective that synthesizes developments in (1) science studies, e.g., history, philosophy and sociology of science and (2) the learning sciences, e.g., cognitive science, philosophy of mind, educational psychology, social psychology, computer sciences, linguistics, and (3) educational research focusing on the design of learning environments that promote dynamic assessments. Taken together these three domains have reshaped our thinking about the role inquiry, and in turn the laboratory, has in science
This paper explores the role of laboratory and field-based research experiences in secondary science education by summarizing research documenting how such activities promote science learning. Classroom and field-based "lab work" is conceptualized as central components of broader scientific investigations of the natural world conducted by students. Considerations are given to nature of professional scientific practice, the personal relevance of student's understanding of the nature of empirical scientific research, and the role of technology to support learning. Drawing upon classroom learning
In the science education research literature, it often appears to be assumed that students "possess" more or less stable "images of science" that directly correspond to their experiences with scientific practice in science curricula. From cultural-historical and sociocultural perspectives, this assumption is problematic because scientific practices are collective human activities and are therefore neither identical with students' experiences nor with the accounts of these experiences that students make available to researchers. "Students' images of science" are therefore translated from

The National Center for Earth-surface Dynamics (NCED) is a Science and Technology Center focused on understanding the processes that shape the Earth's surface, and on communicating that understanding with a broad range of stakeholders. NCED's work will support a larger, community-based effort to develop a suite of quantitative models of the Earth's surface: a Community Sediment Model (CSM). Results of the NCED-CSM collaboration will be used for both short-term prediction of surface response to natural and anthropogenic change and long-term interpretation of how past conditions are recorded in landscapes and sedimentary strata. This will in turn help solve pressing societal problems such as estimation and mitigation of landscape-related risk; responsible management of landscape resources including forests, agricultural, and recreational areas; forecasting landscape response to possible climatic and other changes; and wise development of resources like groundwater and hydrocarbons that are hosted in buried sediments. NCED education and knowledge transfer programs include exhibits and educational programs at the Science Museum of Minnesota, internships and programs for students from tribal colleges and other underrepresented populations, and research opportunities for participants from outside core NCED institutions. The Earth's surface is the dynamic interface among the lithosphere, hydrosphere, biosphere, and atmosphere. It is intimately interwoven with the life that inhabits it. Surface processes span environments ranging from high mountains to the deep ocean and time scales from fractions of a second to millions of years. Because of this range in forms, processes, and scales, the study of surface dynamics has involved many disciplines and approaches. A major goal of NCED is to foster the development of a unified, quantitative science of Earth-surface dynamics that combines efforts in geomorphology, civil engineering, biology, sedimentary geology, oceanography, and geophysics. Our research program has four major themes: (1) landscape evolution, (2) basin evolution, (3) biological sediment dynamics, and (4) integration of morphodynamic processes across environments and scales. Each theme area provides opportunities for exchange of information and ideas with a wide range of stakeholders, including teachers and learners at all levels; researchers, managers, and policy makers in both the commercial and public sectors; and the general public.

The goal of a two-year SEPA grant, Phase II of a collaboration between Columbia University (CU) and the New York Hall of Science (NYHoS), was to enhance science teaching and learning through the use of portable laboratories and hands-on modules to study biotechnology and microscopy in middle and secondary school classes. Four multi-day workshops were held at the NYHoS to train teachers to use the portable laboratory kits. The primary goals of this evaluation are to assess: 1) the workshops' value for teaching the hands-on kit curriculum, 2) teachers' perception of the portable laboratories'

PolarTREC (Teachers and Researchers Exploring and Collaborating) is a three-year teacher professional enhancement program that will advance polar science education by bringing K-12 educators and polar researchers together in hands-on field experiences in the Arctic and Antarctic. PolarTREC activities and products will foster the integration of research and education to produce a legacy of long-term teacher-researcher collaborations, improvement of teacher content knowledge and teaching practices, shareable online learning resources based on real-world science, improved student knowledge of and interest in the Arctic and Antarctic, and broad public engagement in polar science. ARCUS will adapt and extend existing Teacher Research Experience (TRE) models and its own experience delivering TREC -- a TRE program supported by NSF for the Arctic -- to develop PolarTREC, a comprehensive, sustained field research experience program for K-12 teachers focusing on IPY science themes at both polar regions. Thirty-six teachers will spend two to six weeks in the Arctic or Antarctic studying a topic relevant to one of the IPY emphasis areas, with "Live from IPY" calls, Internet presentations, and podcasts from the field, daily teacher journals, interactive bulletin boards, photo galleries, online multimedia learning resources and activities, and participation in CARE (Connecting Arctic/Antarctic Researchers and Educators) web-meetings to support translation of experiences into the classroom and beyond. PolarTREC is relevant to the education goals of the IPY by 1) providing a hands-on field research experience that can be realistically implemented in the polar regions; 2) broadly disseminating teacher experiences to students and other professionals; 3) developing a sustainable learning community; and 4) providing clear and appropriate measures of project success through a formative and summative evaluation. Additionally, the PolarTREC evaluation will provide a basis for replicating or expanding the program structure and best practices. PolarTREC will benefit from close coordination with logistics providers and international programs to ensure operational feasibility and an international reach.
CENTC's (Center for Enabling New Technologies Through Catalysis) outreach is focused on partnerships with science centers. Initially we worked with the Pacific Science Center (PSC) to train our students in effective communication of science concepts to public audiences. Later we developed a short-term exhibit, Chemist - Catalysts for Change in the Portal to Current Research space. As part of the CCI/AISL partnership program, we partnered with Liberty Science Center to create an activity on a multi-touch media table, "Molecule Magic." We are currently developing another exhibit with PSC.
This project by the Oregon Museum of Science and Industry (OMSI) develops a public education program on chemistry. The program: introduces students and the general public to the science of chemistry and processes of chemistry-related research through drop-in lab activities; provides follow-up chemistry activities for use by elementary teachers and parents so that children can further explore the interests they have developed in science and chemistry; provides opportunities for internships for high-school students as lab assistants so that they can develop greater knowledge of "everyday" chemistry, laboratory techniques and safety, develop skills in working with others and in teaching chemistry, and explore potential careers in teaching chemistry; and make available the resources developed by OMSI to other interested science museums.
Temple University's "Sisters in Science in the Community (SISCOM)" is a constructivist-based, inclusive youth/community project targeting underrepresented urban middle and high school girls in grades 6-10 and their families; it supports inclusion of girls with disabilities. It engages girls and their parents in hands-on, inquiry-based sports science in after-school, Saturday, and summer programs co-hosted by community-based organizations and Temple University. Girls will also be engaged in student-centered research projects guided by female scientists. With regard to intellectual merit, SISCOM is based on previous research done by Temple on methods for engaging girls and their parents in STEM activities. The infrastructure of research and practices in education will be facilitated through the sharing of information between the network of partners and the national community of formal and informal educators
The overall goal of the current proposal is to adapt the interdisciplinary research-based curriculum created at the School for Science and Math at Vanderbilt (SSMV) for implementation of a four-year program in three Metropolitan Nashville Public School (MNPS) high schools. The specific aims of the proposal are to adapt the on-campus (at Vanderbilt) model for implementation in three public high schools with different academic profiles (SSM Academies); to define the variables and features required to sustain the program and to replicate the model in any high school setting; and to define a strategy for disseminating the model to additional schools. Students entering 9th grade in a school in which an SSM Academy has been implemented will be encouraged to apply. Those who are accepted into the program will spend three hours every other day in two courses based on the adapted curriculum. As with the SSMV, rising seniors will have opportunities to enter Vanderbilt laboratories for summer research internships. Teachers from the high school will work with Center for Science Outreach scientists to adapt the SSMV curriculum for implementation. Ongoing, year-long teacher professional development will be conducted to ensure that the curriculum is dynamic and the teachers are well-prepared to engage and guide the students in the curriculum. The anticipated outcomes include enhanced student achievement as measured by GPA, and scores on ACT science reasoning and end of course tests; increased SSM student interest in careers in science; increased district-wide enrollment in SSM programs; increased graduation rates and postsecondary education enrollment by SSM students; development of unique curricular science units that can be adapted for a novel four-year interdisciplinary research- based curriculum; development of a sustainable model built on effective features of each SSM that can be exported to other high schools within and outside Nashville; enhanced community and family involvement in the SSM programs and school community in general; a strengthened partnership between Vanderbilt and MNPS that will serve as a national model of a successful university-K-12 collaboration to enhance science teaching and learning.
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.
