Collaboration Scripts A Conceptual Analysis
This article presents a conceptual analysis of collaboration scripts used in face-to-face and computer-mediated collaborative learning. Collaboration scripts are scaffolds that aim to improve collaboration through structuring the interactive processes between two or more learning partners. Collaboration scripts consist of at least five components: (a) learning objectives, (b) type of activities, (c) sequencing, (d) role distribution, and (e) type of representation. These components serve as a ba
Construction dun protocole expérimental avec un logiciel dédié : apprentissages visés et diffi
Les travaux de recherche présentés ici concernent l'évaluation dune séance de Travaux Pratiques (TP) de chimie qui a la particularité de pouvoir être réalisée intégralement à distance. Au cours de cette séance, les apprenants doivent concevoir un protocole expérimental permettant de doser le colorant E124 d'un sirop de grenadine. Pour cela, ils utilisent un logiciel dédié, accessible par internet. La manipulation est effectuée à distance par un robot manipulateur, selon le prot
Mechanisms for Facilitating a Vital and Dynamic Education System: Fundamental Roles for Education Sc
This report was prepared as one component of an OTA project entitled "Educational Technology: An Assessment of Practice and Potential," requested by the U.S. House Committee on Education and Labor. The objectives of our particular project were: (1) synthesize current activities and directions of research in education science (the cognitive, social and instructional sciences), and (2) characterize how opportunities brought about by theoretical advances in education science and developments in mul

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.

"The Bad News From Chicago": Labor Organizer Oscar Ameringer Describes the Effect of the Haymarket B
The Haymarket bombing in 1886 marked a major turning point in the history of nineteenth-century labor. Used by capitalists as an excuse for a crackdown on labor organizations, the bombing also splintered what up had been until then the strongest labor organization in the United States--the Knights of Labor. The anti-labor reaction that followed in the wake of the bombing helped precipitate a rapid decline in membership in the Knights which was eventually supplanted by the American Federation of

"The Men Seem To Be Pretty Well Satisfied": John Anderson on the 1919 Steel Strike
In the dramatic 1919 steel strike, 350,000 workers walked off their jobs and crippled the industry. The U.S. Senate Committee on Education and Labor set out to investigate the strike while it was still in progress. In his testimony before the committee, John Anderson, a helper in the open-hearth furnace at the Homestead steelworks in Pennsylvania, maintains that the steelworkers were satisfied with conditions. Although born in Scotland, Anderson identified himself as an"American" in distinction
