De l'usager construit à l'usager participant
Ce texte part du constat de la faible diffusion des artefacts produits par la recherche en EIAH. Cette situation résulte, nous semble-t-il, d'une forte discontinuité entre les moments de conception et d'usage pouvant entraîner une discordance entre usages imaginés (prédictifs) et usages « réels ». La conception participative, parce qu'elle repense la place de l'usager, nous paraît être à la fois une réponse possible à cette problématique et un champ de recherche pour l'ingénierie
How GRID could improve E-Learning in the environmental science domain
This paper will outline the requirements for an interactive e-learning system defined as part of the German research project GIMOLUS . After a short overview over the Open Grid Service Architecture (OGSA) it will be shown that the capabilities of existing e-learning solutions are too limited in order to fulfil these requirements. The last part will show how a GIMOLUS system could be built using a GRID service architecture and what the benefits are in doing so.

A Golden Opportunity for Science
A Golden Opportunity for Science is an educational exercise developed by the Bureau of Land Management. This exercise uses activities about gold to teach science, centering on the following information: how the pursuit of gold shaped society; metaphors, myths, lores and legends about gold; the mineral properties of gold; lode deposits and placer deposits; mining and recovery of gold; and the technology of heap leaching. There is also a debate between different interest groups involving a small g
"Their Own Hotheadedness": Senator Benjamin R."Pitchfork Ben" Tillman Justifies Violence Against Sou
In this March 23, 1900, speech before the U.S. Senate, Senator Benjamin R. "Pitchfork Ben" Tillman of South Carolina defended the actions of his white constituents who had murdered several black citizens of his home state. Tillman blamed the violence on the "hot-headedness" of Southern blacks and on the misguided efforts of Republicans during the Reconstruction era after the Civil War to "put white necks under black heels." He also defended violence against black men, claiming that southern whit
"The Baby Was Made 'Delegate No. 800'": Frances Willard Meets Elizabeth Rodgers in the 1880s
The commitment of the Knights of Labor to equality for women was more than rhetorical, as seen in the career of Elizabeth Rodgers, the Master Workman, or head, of the organization's giant Chicago District No. 24. This 1889 portrait of Rodgers, offered by leading national anti-liquor activist Frances Willard, underscored the desire on the part of many Knights, both men and women, to connect the struggle for labor reform with a broader vision that included vehement opposition to liquor. It also sh
"Oh God, For One More Breath": Early 20th century Tennessee Coal Miners' Last Words
Coal mining and railroad work were the two most dangerous trades in the United States in the early 20th century. Coal miners frequently died in spectacular explosions and cave-ins that could kill dozens or even hundreds at a time. Although most testimony about coal mining disasters came from survivors and observers, the men who suffocated to death in the Fraterville, Tennessee mines in May 1902 left behind their own grim account. Trapped in the mine after an explosion and with their air rapidly
Haymarket Martyr Albert Parsons's Last Words to His Wife
The Chicago radicals convicted of the infamous May 4, 1886 Haymarket Square bombing in which one policeman was killed remained openly defiant to the end. In his final letter to his wife, written August 20, 1886 from the Cook County "Bastille" (jail), convicted Haymarket bombing participant Albert R. Parsons, an Alabama-born printer, admitted that the verdict would cheer "the hearts of tyrants," but still optimistically predicted that "our doom to death is the handwriting on the wall, foretelling
"Everything Was Lively": David Hickman Describes the Prosperity Late Nineteenth-Century Railroads Br
The availability of rail connections often determined whether a western community would survive or die. The rails fostered prosperity by bringing both goods and people. This trade, and the local service industries that sprouted up to capitalize on the movement of people and goods, drove many local economies. Here, David Hickman talked about the boom years that followed the arrival of the railroad in the Latah County, Idaho town of Genesee in the 1880s.
Microbiology Online is joint project of Society for General Microbiology (SGM) and the Microbiology in Schools Advisory Committee (MISAC) to provide support for microbiology education. The project provides teaching resources from SGM and MISAC, advice for teaching microbiology, information on teaching practical microbiology and low-cost training for teachers. Users can follow links to information on why we study microbiology, microbiology safety, facts and FAQ's and additional links.

McNamara's Whiz Kid
Alain Enthoven, an MIT economist, was the country's first assistant secretary of defense for systems analysis from 1965 to 1969. In this video segment, Enthoven recounts how public interpretation of 'flexible response' strategy ran counter to both the administration's overriding goal-to prevent nuclear war-and its bottom line: that nuclear war is unwinnable. In his interview conducted for War and Peace in the Nuclear Age: 'The Education of Robert McNamara,' Enthoven sets the stage for the missil

Windows Into Wonderland - Yellowstone Electronic Field Trips
The geysers and hot springs of Yellowstone are surface manifestations of larger geological processes—the study of which has attracted scientists for more than 100 years. This 55 minute interactive program discusses how early studies were conducted in the park and illustrates that scientific research is an ongoing process. Students will learn how research methods change with technological advances and examine current investigations into the geologic forces of the vast living laboratory of Yello
