The aim of this project is to communicate the basic laws of particle physics with Feynman diagrams - visual tools which represent elementary particle processes. They were originally developed as a code to be used by physicists and are still used today for calculations and elaborations of theoretical nature. The technical and mathematical rules of Feynman diagrams are obviously the exclusive concern of physicists, but on a pictorial level they can help to popularize many concepts, ranging from matter and the antimatter; the creation, destruction and transformation of particles; the role of
In this chapter, we argue that the understanding of objects that children of different ages brings to the museum setting offers a unique perspective. Little direct work on this topic has been conducted in museums. However, there is a body of related work to be found in contemporary studies of children's emerging understanding of the natural and artificial worlds that can be used to develop a framework for understanding how children might approach the world of museum objects. Recent evidence on the development of children's thinking on this subject is presented in the larger context of the
Designs for CSCL (Computer-Supported Collaborative Learning) applications usually presume a desktop or laptop computer. Yet future classrooms are likely to be organized around Wireless Internet Learning Devices (WILD) that resemble graphing calculators, Palm, or Pocket-PC handhelds, connected by short-range wireless networking. WILD learning will have physical affordances that are different from today’s computer lab, and different from classrooms with 5 students per computer. These differing affordances may lead to learning activities that deviate significantly from today’s images of K-12 CSCL
In this chapter we introduce the notion of islands of expertise, explore links between related socio-cultural and information processing theory, and overview a study of family conversations while parents and children look at authentic and replica fossils in a museum.
After-school programs, scout groups, community service activities, religious youth groups, and other community-based activities have long been thought to play a key role in the lives of adolescents. But what do we know about the role of such programs for today's adolescents? How can we ensure that programs are designed to successfully meet young people's developmental needs and help them become healthy, happy, and productive adults? Community Programs to Promote Youth Development explores these questions, focusing on essential elements of adolescent well-being and healthy development. It
Women in the United States are underrepresented in science, mathematics, and engineering (SME) educational programs and careers. One cause is the dramatic and disproportionate loss of women who intended in high school to pursue science-related careers. This article uses the longitudinal survey responses of 320 male and female SME summer program students to assess the ways in which their social relationships and experiences affect their involvement in science and technology. The issues are framed in terms of identity theory. Structural equation models support the identity framework; emotionally
We used meta-analysis to review 55 evaluations of the effects of mentoring programs on youth. Overall, findings provide evidence of only a modest or small benefit of program participation for the average youth. Program effects are enhanced significantly, however, when greater numbers of both theory-based and empirically based "best practices" are utilized and when strong relationships are formed between mentors and youth. Youth from backgrounds of environmental risk and disadvantage appear most likely to benefit from participation in mentoring programs. Outcomes for youth at-risk due to

This paper describes the integration of handheld computer technology into an existing web-based educational platform, the Web-based Inquiry Science Environment (WISE) and the synergy it produces. This solution facilitated a research program that explores how handheld computers (PDAs, palmtops, etc.) can expand the scope and functionality of inquiry activities in K-12 science and mathematics curriculum. The paper presents the WISE software and curriculum and explains how combining it with handheld technology creates unique educational opportunities. It then goes on to describe the system that
In April 2001, the Museum of Science in Boston launched the Current Science & Technology Center, an effort to address leading edge research for school and public audiences and to provide depth and context for science and technology stories in the news within a museum context and through various outreach methods. The Museum of Science (MOS), in collaboration with the Institute for Learning Innovation (Institute), has initiated a multi-year evaluation effort designed to support the Current Science & Technology Center and its Health Science Education Partnership through (1) the monitoring and
This paper reports the results of a study designed to determine people's preferences for different types of Web-based educational activity. Researchers identified six activity types for comparison: Creative Play, Guided Tour, Interactive Reference, Puzzle/Mystery, Role-playing Story and Simulation. They collected two sets of data: 1) user exit surveys evaluating the study site and preferred genre or type of learning activity and 2) serve statistics indicating the duration of stay. Researchers found clear differences in preferences between adults and children.
In spite of their importance and abundance, we do not know much about the spiders in Los Angeles. There are no truly large collections of urban spiders from this area, as most collectors concentrate on studying natural areas. As an important international port, new species of spiders from various parts of the world are always being accidentally introduced into the Los Angeles area, and some of these have established breeding populations. We need to know how widespread these introduced species have become, and how they have interacted with the native spiders. Also, we want to know how urbanization and the loss of natural habitat has affected populations and distributions of naturally occurring spiders.
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.
