Internal and external collaboration scripts in web-based science learning at schools
Collaboration scripts can help learners to engage in argumentation and knowledge acquisition. However, they might have differential effects for learners holding differently structured knowledge (internal scripts) on argumentation. We investigated how external scripts interact with learners internal scripts concerning collaborative argumentation. 98 students from two secondary schools participated. Two versions of an external collaboration script (high vs. low structured) supporting argumentati
Six Years of Knowledge Networking in Learning Sciences and Technologies
This report presents a series of in-depth reflections about the work of the Center for Innovative Learning Technologies (CILT) from 1997 until 2004. Each member of the CILT team (Principal investigator, postdoctoral scholar, project coordinator and manager) provided their personal reflections on what they, and all of us as a group, have learned from the attempt to stimulate the development and implementation of important, technology-enabled solutions to critical problems in K-14 STEM learning in
Calculators, graphs, gestures and the production of meaning
In this paper we report an analysis of a teaching sequence in which Grade 11 students were asked to produce some graphs corresponding to the relationship between time and distance of a cylinder moving up and down an inclined plane. The students were also asked to carry out the experience using a TI 83+ graphic calculator equipped with a sensor, and to discuss and explain the differences between their own graphs and the ones obtained with the calculator. We analyze the students' processes of mea
Developing continuous air during articulation
Combining long tones and burst-tonguing will assist many beginning instrument players to eliminate excessive breaths while articulating.
Kaleidoscope JEIRP on Learning Patterns for the Design and Deployment of Mathematical Games: Final R
Over the last few years have witnessed a growing recognition of the educational potential of computer games. However, it is generally agreed that the process of designing and deploying TEL resources generally and games for mathematical learning specifically is a difficult task. The Kaleidoscope project, "Learning patterns for the design and deployment of mathematical games", aims to investigate this problem. We work from the premise that designing and deploying games for mathematical learning re
The Road to Brown

"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
"I'm Going to Fight Like Hell"Anna Taffler and the Unemployed Councils of the 1930s
The Communist-led Unemployed Councils mobilized jobless men and women in hundreds of local communities to demand jobs and better treatment from relief authorities. In these excerpts from a recorded interview, Anna Taffler, a Communist activist and a Russian Jewish immigrant, described how her own experience of facing eviction pushed her into organizing the unemployed. She also talked about the focus of local councils on issues like fighting for more relief and stopping evictions.

Reducing Volcanic Hazards to People and Property - An Assignment with Electronic Peer Review
Through an electronic peer review assignment, students write a general summary of major hazards to humans in the vicinity of volcanoes. Then, students are provided a list of volcanoes and must choose one to determine what actions they would take to minimize the risks to a population. This activity is detailed on this Starting Point site, which includes its learning goals, context for use, teaching notes and materials, recommended assessment method, resources, and references.

'Way Downtown' combines animated and electronically enhanced still images with scenes of public life from an Asian culture. In the opening sequence a still image is slowly animated to show frantically ticking clocks. Images from advertising and mass media are juxtaposed against scenes of window washers and street crowds. Driving rock music, 'Guitar Trio,' by Rhys Catham accompanies the work. The piece is approximately eight minutes long and was broadcast as a segment of episode 303 (1987) of 'Ne

The surreal narration playfully kidnaps our imagination, taking us beyond the everyday world.' In this work written, produced, and directed by Dennis Day, trios of flying businessmen, cowgirls, and women who appear to have walked off the surface of a billboard roam city streets and suburban sprawl. Additional characters make appearances in this brightly-colored landscape,
