Integrating The Study Of Technology Into The Curriculum: A Consulting Teacher Model, Thomas Erekson, Steven Shumway

Publications

Over the past 40 years there have been several initiatives by leaders in the profession to make revolutionary changes in philosophy, curriculum, methods, and facilities in the transition from industrial arts to technology education. The transition to technology education has been grounded in the dramatic changes that technology and technological innovations have brought to all aspects of society. It has been postulated that to fully participate in a technologically-based society, people must be technologically literate (Pearson & Young, 2002). Thus, the need arose to assure that all students have experience in technology education in order to acquire technological literacy.

Review Of The Book - Teaching About Technology: An Introduction To The Philosophy Of Technology For Non-Philosophers, Vincent Childress

Publications

Marc de Vries' latest book, Teaching about Technology: An Introduction to the Philosophy of Technology for Non-Philosophers, was interesting to the reviewer because it provided a link between philosophies of technology and the nature of the technology curriculum more than any other philosophy-related work he has read. The book is intended for use with pre-service teachers, graduate students, and others who are interested in teaching technology. Teaching about Technology is part of a series of books on science and technology that is edited by William Cobern of Western Michigan University in Kalamazoo, Michigan. The editorial board for the series is …

Creativity: A Framework For The Design/Problem Solving Discourse In Technology Education, Theodore Lewis

Publications

Subjects for which aesthetics and creative performance are critical curricular dimensions (such as art, physical education, music, and technology education), and which are accommodative of students across the range of intelligences (Gardner, 1999) are not readily or completely captured by content standards. Therefore content knowledge in these fields that target student achievement as conventionally conceived must be complemented by treatment of more subjective and elusive goals such as the development of connoisseurship, appreciation, or creative insight. With the publication of standards for the subject (International Technology Education Association, 2000), the need for focus upon creativity in technology education has been …

New Perspectives: Technology Teacher Education And Engineering Design, Roger B. Hill

Publications

Initiatives to integrate engineering design within the field of technology education are increasingly evident (Lewis, 2005; Wicklein, 2006). Alliances between technology education and engineering were prominent in the development of the Standards for Technological Literacy (International Technology Education Association, 2000), and leaders from both disciplines have expressed support for the outcomes described in the Standards (Bybee, 2000; Council of the National Academy of Engineering, 2000; Dugger, Meade, Delany, and Nichols, 2003; Gorham, Newberry, and Bickart, 2003). The National Science Foundation (NSF) has also encouraged and funded opportunities for technology educators and engineers to work collaboratively. The Bridges for Engineering Education …

Five Good Reasons For Engineering As The Focus For Technology Education, Robert C. Wicklein

Publications

The article presents information on a paper which discusses why engineering design should be the focus for technology education. Technology education is still viewed as a non-essential instructional program and this is because school administrators and counselors have inadequate understanding of it. Even general populace have inadequate understanding concerning technology education. The pervasiveness of technology literally affects every living creature in our society. Therefore, it is of critical importance that the educational system includes and supports the study of technology in the general curricula. The deficiency within the technology education profession to formulate a clear and defined target for the …

Publications

The rapid development of new sensors and wide-band communications provides the capability to collect enormous amounts of data. An increasing challenge involves how to understand and interpret the data to yield knowledge about evolving situations or threats (e.g., of military situations, state of complex systems, etc.). New visualization tools and techniques are becoming available to support advanced visualization including three-dimensional, full immersion display environments and tools to support novel visualizations. Examples include network system display tools and evolving multi-sensory situation environments. Despite the emergence of such tools, there has been limited systematic test and evaluations to determine the efficacy of …

Winds Of Change?: Projections Of Near-Surface Winds Under Climate Change Scenarios, S C. Pryor, Justin T. Schoof, R J. Barthelmie

Publications

Changes in near–surface wind speeds due to global climate change may have profound geophysical and societal impacts. However, Global Climate Models (GCMs) are unable to replicate the historically observed magnitude and spatial variability of wind speeds, so we apply a downscaling technique to generate probability distributions of wind speeds at sites in northern Europe for historical periods (1961–1990 and 1982–2000) and two future periods (2046–2065, 2081–2100). Projections for the twenty-first century (C21st) indicate no evidence of substantial evolution relative to the end of the twentieth century (C20th), although there is increased divergence of results from downscaling of different GCMs toward …

Composting Of Biodegradable Municipal Waste In Ireland, Niamh Power, Jerry D. Murphy

Publications

The implementation of the Landfill Directive (96/31/EC) will lead to a massive reduction in quantities of Biodegradable Municipal Waste (BMW), which may be landfilled. In 2016, an estimated 2.6 million tonnes of BMW will require diversion from landfill in Ireland. Recycling of dry paper, reuse of textiles and home composting will divert significant quantities of BMW. However, to divert the quantities required to comply with the Directive a significant proportion of the Organic Fraction of Municipal Solid Waste (OFMSW) will require treatment in centralised biological facilities. A survey was undertaken of composting facilities in Ireland to ascertain present capacity, present …

The Unexpected Value Of Litigation: A Real Options Perspective, Joseph A. Grundfest, Peter H. Huang

Publications

In this Article, we suggest that litigation can be analyzed as though it is a competitive research and development project. Developing this analogy, we present a two-stage real option model of the litigation process that involves sequential information revelation and bargaining over the surplus generated by early settlement. Litigants are risk-neutral and have no private information. The model generates results that, we believe, have analytic and normative significance for the economic analysis of litigation

From an analytic perspective, we demonstrate that negative expected value (NEV) lawsuits are analogous to out of the money call options held by plaintiffs and that …

Modeling Bus Priority Using Intermodal Dynamic Network Assignment-Simulation Methodology, Khaled F. Abdelghany, Ahmed F. Abdelghany, Hani S. Mahmassani, Akmal S. Abdelfatah

Publications

This article presents a modeling framework that represents bus priority at signalized intersections in the context of its potential network-level and intermodal effects. The model incorporates bus priority within an intermodal dynamic traffic assignment simulation model. It dynamically assigns travelers to different modes and routes in the network according to prevailing traffic conditions, which result from applying a certain network control/bus priority scheme. The model considers changes in traffic conditions as a result of (1) drivers’ route choice adjustments due to changes in traffic signals settings and (2) modal shifts by travelers to take advantage of improved transit service. Three …

Experimental Investigation Of The Velocity Field In Buoyant Diffusion Flames Using Piv And Tpiv Algorithm, Lulu Sun, Xiangyang Zhou, Shankar Mahalingam, David R. Weise

Publications

We investigated a simultaneous temporally and spatially resolved 2-D velocity field above a burning circular pan of alcohol using particle image velocimetry (PIV). The results obtained from PIV were used to assess a thermal particle image velocimetry (TPIV) algorithm previously developed to approximate the velocity field using the temperature field, simultaneously captured by an infrared (IR) thermal camera. By tracing “thermal particles,” which were assumed to be virtual particles that corresponded to pixels of temperature values in successive IR images, the TPIV algorithm estimated a larger scale instantaneous velocity field than either a single-point velocity measurement (e.g., LDV) or the …

Publications

Sounding rocket experiments were conducted during the NASA EQUIS II campaign on Kwajalein Atoll designed to elucidate the electrodynamics and layer structure of the postsunset equatorial F region ionosphere prior to the onset of equatorial spread F (ESF). Experiments took place on 7 and 15 August 2004, each comprised of the launch of an instrumented and two chemical release sounding rockets. The instrumented rockets measured plasma number density, vector electric fields, and other parameters to an apogee of about 450 km. The chemical release rockets deployed trails of trimethyl aluminum (TMA) which yielded wind profile measurements. The Altair radar was …

An Environmental Pool For The Rio Grande, Kara Gillon

Publications

The Bureau of Reclamation and Corps of Engineers operate a series of dams, reservoirs, and levees along the Middle Rio Grande of New Mexico. The plight of the Rio Grande silvery minnow, an endangered species, and of the river itself demonstrates the need for a change from the emphasis on water development to sustainable river management. Conservation groups invoked the protections of the Endangered Species Act to catalyze this change. Recognizing that flexibility is necessary to meeting competing water needs, the groups also promoted the need for and several approaches to a sustainable and long-term approach to river management and …
