University Students Promoting Science in the Community

Project SEARCH (Science Education and Research for Children) has brought these undergraduate students here today. It is an outreach program designed to bring the science resources of a large research university to classrooms and community centers. For the past 9 years, SEARCH students have spent 4 hours each week doing hands-on-science experiments, dissecting frogs, demonstrating microscopes, lecturing about the planets, playing computer games, exploring the World Wide Web, and creating Web pages.published or submitted for publicationis peer reviewe

Network-Based Classrooms

Computer-mediated communication is an increasingly familiar part of the educational experiences of students from elementary school through graduate school. This is not surprising, because electronic mail, bulletin boards, gopher servers, and other forms of telecommunication offer conveniences and exciting new possibilities for learning. The rapid expansion of the Internet, the availability of low-cost modems and high-speed data lines, and a growing awareness of the educational possibilities are leading to major changes in classrooms. The many ways in which network-based classrooms are used highlights questions about the goals and means of education that are too often pushed aside. By affording new ways of communicating, these classrooms ask us to rethink questions such as: What role should the teacher have in the classroom? How can students support each other???s learning? What kinds of writing should students learn to do? How should we accommodate, or balance, student interests with other curricular concerns? What is needed to make a classroom become a true learning community? In addition to raising these questions, they provide us with new possibilities for answering them.published or submitted for publicationis peer reviewe

Expert systems and developing expertise: Implications of Artificial Intelligence for Education

This paper discusses a few issues in AI research with the aim of understanding whether the concepts or the tools of AI can be of use in education (see also Green, 1984). Most of the discussion focuses on natural language understanding, one aspect of the highly diverse field of AI.published or submitted for publicationis peer reviewe

Communities of Designers: Transforming a Situation into a Unified Whole

A new player, digital technology, has entered into the already variegated and often contentious world of teaching and teacher education. This new player promises to disrupt existing practices in some as yet undefined way. It is not surprising that its eventual impact on learning or on educational equity is uncertain, when there is still great uncertainty around basic questions such as which digital tools ought to be considered or what they cost. The previous chapters in this book make a major contribution to the conversation about (digital) technology in education. They address three large questions: How should we integrate technology into learning? What happens when we do? How do we learn to do it (possibly better than before)?published or submitted for publicationnot peer reviewe

Beam Loss Control for the Fermilab Main Injector

From 2005 through 2012, the Fermilab Main Injector provided intense beams of 120 GeV protons to produce neutrino beams and antiprotons. Hardware improvements in conjunction with improved diagnostics allowed the system to reach sustained operation at 400 kW beam power. Losses were at or near the 8 GeV injection energy where 95% beam transmission results in about 1.5 kW of beam loss. By minimizing and localizing loss, residual radiation levels fell while beam power was doubled. Lost beam was directed to either the collimation system or to the beam abort. Critical apertures were increased while improved instrumentation allowed optimal use of available apertures. We will summarize the impact of various loss control tools and the status and trends in residual radiation in the Main Injector.Comment: 5 p

Defining the outcomes of community care: the perspectives of older people with dementia and their carers

There is growing recognition of the need for outcome measures which reflect the aims of services for people with dementia. The development and application of existing outcome measures has often marginalised people with dementia. ‘Experts’ and carers have been viewed as primary sources when identifying relevant outcomes or domains of quality of life, and proxy respondents have often been responsible for rating outcomes on the resulting measures. This paper reports a small consultation with people with dementia and their carers to identify the desired outcomes of community care. While there was considerable overlap in the outcomes identified by people with dementia and their carers, a number of limitations of relying solely on carers as proxy respondents were identified. A key outcome, which has been relatively neglected in previous work, was maximising a sense of autonomy. A range of outcomes related to the ways in which services are delivered were also identified. Future evaluative studies should encompass both quality-of-life outcomes and service-process outcomes (the impacts of the ways in which services are delivered) in addition to other outcome measures relevant to the aims and objectives of the service

Spacecraft studies of Phobos and Mars

Utilizing the Termoskan data set of the Phobos '88 mission we have recognized a new feature on Mars: Ejecta blanket Distinct In the THermal infrared (EDITH). Virtually all of the more than one hundred of these features discovered in the Termoskan data are located on the plains near Valles Manneris. EDITH's have a startlingly clear dependence upon terrains of Hesperian age, implying a spatial or temporal dependence on Hesperian terrains. Almost no thermally distinct ejecta blankets are associated with any of the thousands of craters within the data set that occur on the older Noachian units. EDITH's also do not appear on the portions of the younger Tharsis Amazonian units seen in the data. The Hesperian terrain dependence cannot be explained by either atmospheric or impactor variations; Noachian and Hesperian terrains must have experienced identical atmospheric and impactor conditions during Hesperian times. Thermally distinct eject a blankets therefore reflect target material differences and/or secondary modification processes. A further discussion of EIDTH's is presented
