The purpose of this paper is to explore and discuss the role of practical work in the teaching and learning of science at school level. It emphasizes practical work as a means for students to learn about the nature of science.
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
Arizona State University (ASU) in collaboration with Arizona Science Center, Boeing, Intel, Microchip, Motorola, Salt River Project, AZ Foundation for Resource Education, AZ Game & Fish Department, US Partnership for the Decade of Education for Sustainable Development, Mesa Public Schools, and Boys & Girls Clubs of the East Valley, offer a three-year extracurricular project resulting in IT/STEM-related learning outcomes for 96 participants in grades 7, 8, and 9. The project targets and engages female and minority youth traditionally under-represented in IT/STEM fields in multi-year out-of-school technological design and problem solving experiences. These include summer internships/externships and university research in the science center and industrial settings where participants develop socially responsible solutions for challenging real world problems. The program includes cognitive apprenticeships with diverse mentors, opportunities to practice workplace skills such as leadership, teamwork, time management, creativity and reporting, and use of technological tools to gather and analyze complex data sets. Participants simulate desert tortoise behaviors, research and develop designs to mitigate the urban heat island, build small-scale renewable energy resources, design autonomous rovers capable of navigating Mars-like terrain, and develop a model habitat for humans to live on Mars. Together with their families participants gain first-hand knowledge of IT/STEM career and educational pathways. In addition to youth outcomes, the adults associated with this project are better prepared to positively influence IT/STEM learning experiences for under-represented youth. The evaluation measures participant content knowledge, attitudes and interest in IT/STEM subjects, workplace skills and intentions to pursue IT/STEM educational and career pathways to understand participant reactions, learning, transfer and results. Informal curricula developed through this project, field-tested with youth at Boys & Girls Clubs and youth at Arizona Science Center will be available on the project website.

The "Salmon Research Team: A Native American Technology, Research and Science Career Exposure Program" is a three-year, youth-based ITEST project submitted by the Oregon Museum of Science and Industry. The project seeks to provide advanced information technology and natural science career exposure and training to 180 middle level and high school students. Mostly first-generation college-bound students, the target audience represents the Native American community and those with Native American affiliations in reservation, rural and urban areas. Students will investigate computer modeling of complex ecological, hydrological and geological problems associated with salmon recovery efforts. Field experiences will be provided in three states: Oregon, Washington and northern California. The participation of elders and tribal researchers will serve as a bridge between advanced scientific technology and traditional ecological knowledge to explore sustainable land management strategies. Students will work closely with Native American and other scientists and resource managers throughout the Northwest who use advanced technologies in salmon recovery efforts. Student participation in IT-dependent science enrichment and research activities involving natural science fields of investigation will occur year round. Middle school students are expected to receive at least 330 contact hours including a one-week summer research experience, a one-week spring break program, and seven weekends of residential programs during the school year. The high school component consists of 460 contact hours reflecting one additional week for the summer research experience. In addition to watershed and salmon recovery related research, students will be involved in other ancillary research projects. A vast array of partners are positioned to support the field research experience including, for example, the U.S. Department of the Interior, Redwood National State Park, College of Natural Resources and Sciences at Humboldt State University, Confederated Tribes of the Warm Springs, University of Oregon Institute of Marine Biology, University of Washington Columbia Basin Research project, the Northwest Center for Sustainable Resources at Chemeketa Community College and the Integrated Natural Resource Technology program at Mt. Hood Community College. The project is intended to serve as a model for IT-based youth science programs that address national and state education standards and are relevant to the cultural experience of Native American students. Two mentors will provide continued support to students: an academic mentor at the student's schools and a professional mentor from a local university or natural resource agency. Incentives will be provided for student participation including stipends and internships. Career exposure and work-related skills are integrated throughout the project activities and every program component. Creative strategies are used to encourage family involvement including, for example, salmon bakes and museum discounts.

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'

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.
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.
Having developed the concept of near-peer mentorship at the middle school/high school level and utilized it in a summer science education enhancement program now called Gains in the Education of Mathematics and Science or GEMS at the Walter Reed Army Institute of Research (WRAIR), it is now our goal to ultimately expand this program into an extensive, research institute-based source of young, specially selected, near-peer mentors armed with kits, tools, teacher-student developed curricula, enthusiasm, time and talent for science teaching in the urban District of Columbia Public Schools (specific schools) and several more rural disadvantaged schools (Frederick and Howard Counties) in science teaching. We describe this program as a new in-school component, involving science clubs and lunch programs, patterned after our valuable summer science training modules and mentorship program. Our in-house program is at its maximum capacity at the Institute. Near-peer mentors will work in WRAIR's individual laboratories while perfecting/adapting hands-on activities for the new GEMS-X program to be carried out at McKinley Technology HS, Marian Koshland Museum, Roots Charter School and Lincoln Junior HS in DC, West Frederick Middle School, Frederick, MD and Folly Quarter Middle School and Glenelg HS, in Howard County, MD. Based on local demographics in these urban/rural areas, minority and disadvantaged youth, men and women, may choose science, mathematics, engineering and technology (SMET) careers with increasing frequency after participating, at such an early age, in specific learning in the quantitative disciplines. Many of these students take challenging courses within their schools, vastly improve their standardized test scores, take on internship opportunities, are provided recommendations from scientists and medical staff and ultimately are able to enter health professions that were previously unattainable. Relevance to Public Health: The Gains in the Education of Mathematis and Science (GEMS) program educates a diverse student population to benefit their science education and ultimately may improve the likelihood of successfully entry into a health or health-related professions for participating individuals. Medical education has been show to improve public health.
