Students conceptions: an introduction to a formal characterization
We investigate in this paper the complexity of modeling students knowing of mathematics under the constraints of acknowledging both their possible lack of coherency and their local efficiency. For this purpose we propose a formalization of the notion of "conception" as a possible tool to answer the epistemological problem we identify. We apply then this approach to the study of the possible conceptions of "function", from an historical and then an epistemic point of view. We report the result of
Didactique computationnelle, évocation d'un projet de recherche.
L'objet de la didactique computationnelle est l'étude des problèmes liés à la construction, à la mise en oeuvre et au contrôle de processus didactiques représentés par des modèles symboliques calculables au sens du calcul par un dispositif informatique. Cette branche de la didactique est inséparable de la didactique expérimentale. Privée du questionnement épistémologique et de la validation de ses implémentations dans une démarche expérimentale rigoureuse, elle ne serait que la
Scripting argumentative knowledge construction in computer-supported learning environments
Computer-supported collaborative learning (CSCL) environments may encourage learners to engage in argumentative knowledge construction. Argumentative knowledge construction means that learners work together to elaborate on concepts by constructing arguments and counterarguments. This is achieved through discourse with the goal of acquiring knowledge within a specific domain. However, learners may encounter problems relating to one of three dimensions of argumentative knowledge construction. Firs
"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

Frustration versus Fantasy: How the Movies Made Some People Restless
Fears about the impact of movies on youth led to the Payne Fund research project, which brought together nineteen social scientists and resulted in eleven published reports. One of the most fascinating of the studies was carried out by Herbert Blumer, a young sociologist who would later go on to a distinguished career in the field. For a volume that he called Movies and Conduct (1933), Blumer asked more than fifteen hundred college and high school students to write "autobiographies"of their expe
"We Ought to Have the Right to Belong to the Union": Frank Smith Speaks 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, Hungarian-born Frank Smith, a Clairton worker, used his support for the war effort as evidence of his Americanism. "This is the United States," he argued, "and we ought to have the right to belong to the union."

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, W. M. Mink, mill superintendent at the Homestead steelworks, testified that the cause of the strike was simple--the infection of "the Bolshevik spirit"among "the foreigners."
"Eight Hours a Day and Better Conditions": Andrew Pido Explains His Support for the 1919 Steel Strik
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, Slavic steelworker Andrew Pido described the discrimination faced by some immigrant workers and how that discrimination - along with long pay and poor conditions--encouraged them to unionize and strike.

Cross Body Ride
'A celebration of busy movement performed by male dancers jumping, stretching, bumping, and sliding across Venezuela's beaches.' In this duet, two men perform spirited partnering phrases against an oceanside background. Repeatedly, the two are seen lying together in a thin bed, lending an air of eroticism to the work. Black-and-white sequences and still photographs are juxtaposed against the vibrant colors of most of the piece. The score by Charles Nieland features rhythmic electronic music, whi
