Do partners care about their mutual location? Spatial awareness in virtual environments
This paper reports on four experimental studies concerning regard to how people use space so as to solve problems collaboratively in virtual environments. Prior to presenting the results, it summarizes the wide range of literature concerning social uses of spatiality in human interactions. The experiments we conducted revealed that virtual space modifies and improves collaborative processes such as division of labor, grounding, communication, coordination, as well as the performance to the task.
Distance training, a key mode to support teachers in the integration of ICT ? Towards collaborative
The integration of ICT into the teaching and learning of school subjects remains still rather weak, even in highschools. Changes in users' practices required by such integration have probably been underestimated: teachers are obliged to question and change their professional practices. It turns out that standard training sessions towards ICT have been found to be unsuited for supporting teachers in overcoming their difficulties with this integration. This document describes a specific distance,

Middle School Portal: Math and Science Pathways (MSP2)
The popular Learning Adventures series at DiscoverySchool.com (last mentioned in the March 8, 2002 NSDL Physical Science Report) has a feature on the International Space Station. Its assembly is one of the most ambitious engineering projects ever, and this site explains a few of the details of the multi-year process. In the Mission Basics section, there are specific facts, discussions about various aspects of the station, and virtual tours of some of the stations modules. Astronaut profiles and
Size and Scale
Another good lesson plan from DiscoverySchool.com, the Size and Scale Web site gives teachers a well conceived and thorough activity on the physics of size and scale. Objectives of the lesson include: understanding the relative sizes of bodies in our solar system and the problem of making a scale model of the entire solar system (because the distances in space are so great that even a very small scale model would be too large to be practical). The site contains all the information needed to comp

Experimental Design Methods - A Review
Experimental design methods are applied in all phases of the design process and by almost every party involved in the design process. In this paper, we aim to give an overview of the background, applications, and technologies involved. A limited simple metric is introduced for assessing the degree of innovation. Future developments are outlined.

Letters from the Frontier: Reading and Writing Primary Documents
By immersing themselves in primary sources (George Catlin's letters), students will learn the difference between objective and subjective writing styles. They will draw facts out of the letters to create newspaper articles in Activity 1, and write their own letters as if they were members of the Catlin family in Activity 2. These activities are designed to enliven historical figures, to connect the "current events" of the past with the current events of the present, and to help students read and
