Argumentation has become an increasingly recognized focus for science instruction---as a learning process, as an outcome associated with the appropriation of scientific discourse, and as a window onto the epistemic work of science. Only a small set of theoretical conceptualizations of argumentation have been deployed and investigated in science education, however, while a plethora of conceptualizations have been developed in the interdisciplinary fields associated with science studies and the learning sciences. This paper attempts to review a range of such theoretical conceptualizations of
Conceptual change views of teaching and learning processes in science, and also in various other content domains, have played a significant role in research on teaching and learning as well as in instructional design since the late 1970s. An important issue is whether conceptual change can provide a powerful framework for improving instructional practice in such a way that students’ levels of scientific literacy are significantly increased. In this article, the first section provides an overview on the development of conceptual change perspectives. In sections two to six, we examine the
This paper begins with a consideration of some important themes dealt with in the paper by Treagust and Duit. These include the relationship between research on conceptual change and educational practice, the significance of emotion and identity in the process of conceptual change, and role of cognitive conflict in motivating change. I then argue that the authors implicitly assert the importance of spoken dialogue as a motor for conceptual change, but do not give it the proper, explicit recognition that it deserves. I first use their own data of transcribed talk to make this point, and then go
In what ways do urban youths’ hybridity constitute positioning and engagement in science-as-practice? In what ways are they “hybridizing” and hence surviving in a system that positions them as certain types of learners and within which they come to position themselves often as other than envisioned? To answer these questions, I draw from two ethnographic case studies, one a scientist–museum–school partnership initiative, and the other, an after-school science program for girls only, both serving poor, ethnically and linguistically diverse youth in Montreal, Canada. Through a study of the micro
We describe OctoPocus, an example of a dynamic guide that combines on-screen feedforward and feedback to help users learn, execute and remember gesture sets. OctoPocus can be applied to a wide range of single-stroke gestures and recognition algorithms and helps users progress smoothly from novice to expert performance. We provide an analysis of the design space and describe the results of two experiments that show that OctoPocus is significantly faster and improves learning of arbitrary gestures, compared to conventional Help menus. It can also be adapted to a markbased gesture set
The First Synthesis Meeting was held in January 2008, at the front end of the Portal to the Public grant period. For this meeting, forty-three experts, stakeholders and members of the project team came together at Pacific Science Center for two days of dialog and reflection. Participants brought diverse knowledge and experience, and represented public, research scientist and informal science education perspectives. The First Synthesis Meeting's goal was to facilitate in-depth conversation to identify current initiatives, best practices, and future directions regarding activities in the field
"Have You Spotted Me? Learning Lessons by Looking for Ladybugs" is an innovative citizen science project that targets children from Native American, rural, farming, and disadvantaged communities. While most citizen science efforts target teens and adults, this project enables youth ages 5-11 to contribute to the development of a major ladybug database. Adult mentors in youth programs introduce children to topics such as ladybugs, invasive species, biodiversity, and conservation. Youth not affiliated with a program may participate independently. Project deliverables include a self-contained education program, an Internet portal and project website, a dedicated corps of volunteers, and the largest, accessible biological database ever developed. The database is made more reliable by utilizing records accompanied by an identifiable data image as a certified data point. Partners include the NY State 4-H, South Dakota State 4-H, Migrant Worker Children's Education Program, Cayuga Nature Center, Seneca Nation Department of Education Summer Programs, Seneca Nation Early Childhood Learner Centers After School Program, and the Onondaga Nation After School Program. Strategic impact will be realized through the creation of a citizen science project that provides hands-on interactions, field experiences, and accessible data that creates unique learning opportunities for youth. It is estimated that nearly 10,000 youth will be impacted by this work.

This paper explains how and why many American museums of science and nature moved away from the traditional content and methods of natural history in the period from 1930 to 1980. It explores diverse motivations for the shift from dead, stuffed displays to live, interactive exhibits, and the consequences of that shift for museums as both educational institutions and as institutions of research. Ultimately, it argues that debates over museums' content and display strategies drew strength from and reinforced a profound transformation in the institutional history of twentieth-century American
This award is for a Science and Technology Center devoted to the emerging area of nanobiotechnology that involves a close synthesis of nano-microfabrication and biological systems. The Nanobiotechnology Center (NBTC) features a highly interdisciplinary, close collaboration between life scientists, physical scientists, and engineers from Cornell University, Princeton University, Oregon Health Sciences University, and Wadsworth Center of the New York State Health Department. The integrating vision of the NBTC is that nanobiotechnology will be the genesis of new insights into the function of biological systems, and lead to the design of new classes of nano- and microfabricated devices and systems. Biological systems present a particular challenge in that the diversity of materials and chemical systems for biological applications far exceeds those for silicon-based technology in the integrated-circuit industry. New fabrication processes appropriate for biological materials will require a substantial expansion in knowledge about the interface between organic and inorganic systems. The ability to structure materials and pattern surface chemistry at small dimensions ranging from the molecular to cellular scale are the fundamental technologies on which the research of the NBTC is based. Nanofabrication can also be used to form new analytical probes for interrogating biological systems with unprecedented spatial resolution and sensitivity. Three unifying technology platforms that foster advances in materials, processes, and tools underlie and support the research programs of the NBTC: Molecules of nanobiotechnology; Novel methods of patterning surfaces for attachment of molecules and cells to substrates; and Sensors and devices for nanobiotechnology. Newly developed fabrication capabilities will also be available through the extensive resources of the Cornell Nanofabrication Facility, a site of the NSF National Nanofabrication Users Network. The NBTC will be an integrated part of the educational missions of the participating institutions. NBTC faculty will develop a new cornerstone graduate course in nanobiotechnology featuring nanofabrication with an emphasis on biological applications. Graduate students who enter the NBTC from a background in engineering or biology will cross-train in the other field by engaging in a significant level of complementary course work. Participation in the NBTC will prepare them with the disciplinary depth and cross-disciplinary understanding to become next generation leaders in this emerging field. An undergraduate research experience program with a strong mentoring structure will be established, with emphasis on recruiting women and underrepresented minorities into the program. Educational outreach activities are planned to stimulate the interest of students of all ages. One such activity partnered with the Science center in Ithaca is a traveling exhibition for museum showings on the subject of nano scale size. National and federal laboratories and industrial and other partners will participate in various aspects of the NBTC such as by hosting interns, attendance at symposia and scientist exchanges. Partnering with the industrial affiliates will be emphasized to enhance knowledge transfer and student and postdoctoral training. This specific STC award is managed by the Directorate for Engineering in coordination with the Directorates for Biological Sciences, Mathematical and Physical Sciences, and Education and Human Resources.
Researchers at the U.C. Davis will carry out observations of museum visitors to plan for a study of how visualizations affect visitors of an Earth Sciences exhibit using 3D technology. The researchers will be able to conduct an experimental study about how much participants in an education center learn from the model of earthquakes and of a model of the Lake Tahoe basin. The researchers will conduct a quasi-experiment of a sample of 100 visitors to the center at Lake Tahoe to study their experience with visualization and learning of science. The funding for this phase of the project will include the development of audience surveys, conducting focus groups to develop types of feedback, train staff to conduct data collection, and to conduct a literature review of technology visualization.
This Nanoscale Science and Engineering Center (NSEC) is a collaboration among Harvard University, the Massachusetts Institute of Technology, the University of California—Santa Barbara, and the Museum of Science—Boston with participation by Delft University of Technology (Netherlands), the University of Basel (Switzerland), the University of Tokyo (Japan), and the Brookhaven, Oak Ridge, and the Sandia National Laboratories. The NSEC combines "top down" and "bottom up" approaches to construct novel electronic and magnetic devices with nanoscale sizes and understand their behavior, including quantum phenomena. Through a close integration of research, education, and public outreach, the Center encourages and promotes the training of a diverse group of people to be leaders in this new interdisciplinary field.
The Nanoscale Science and Engineering Center entitled New England Nanomanufacturing Center for Enabling Tools is a partnership between Northeastern University, the University of Massachusetts Lowell, the University of New Hampshire, and Michigan State University. The NSEC unites 34 investigators from 9 departments. The NSEC is likely to impact solutions to three critical and fundamental technical problems in nanomanufacturing: (1) Control of the assembly of 3D heterogeneous systems, including the alignment, registration, and interconnection at three dimensions and with multiple functionalities, (2) Processing of nanoscale structures in a high-rate/high-volume manner, without compromising the beneficial nanoscale properties, (3) Testing the long-term reliability of nano components, and detect, remove, or prevent defects and contamination. Novel tools and processes will enable high-rate/high-volume bottom-up, precise, parallel assembly of nanoelements (such as carbon nanotubes, nanorods, and proteins) and polymer nanostructures. This Center will contribute a fundamental understanding of the interfacial behavior and forces required to assemble, detach, and transfer nanoelements, required for guided self-assembly at high rates and over large areas. The Center is expected to have broader impacts by bridging the gap between scientific research and the creation of commercial products by established and emerging industries, such as electronic, medical, and automotive. Long-standing ties with industry will also facilitate technology transfer. The Center builds on an already existing network of partnerships among industry, universities, and K-12 teachers and students to deliver the much-needed education in nanomanufacturing, including its environmental, economic, and societal implications, to the current and emerging workforce. The collaboration of a private and two public universities from two states, all within a one hour commute, will lead to a new center model, with extensive interaction and education for students, faculty, and outreach partners. The proposed partnership between NENCET and the Museum of Science (Boston) will foster in the general public the understanding that is required for the acceptance and growth of nanomanufacturing. The Center will study the societal implications of nanotechnology, including conducting environmental assessments of the impact of nanomanufacturing during process development. In addition, the Center will evaluate the economic viability in light of environmental and public health findings, and the ethical and regulatory policy issues related to developmental technology.
