Current and future usages of E-learning metadata and ontologies.
The purpose of this report is to provide an overview on current and future usages of annotations, metadata and ontologies in the e-learning projects of the JEIRP partners. The first section of this article defines a methodology based on user roles which allows for a structured presentation of the usages. The methodology is used for the description of several current usage scenarios in Section 2. Additionally, this methodology allows identifying open research questions. These are described in det
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.
An Integrated Approach for Analysing and Assessing the Performance of Virtual Learning Groups
Collaborative distance learning involves a variety of elements and factors that have to be considered and measured in order to analyse and assess group and individual performance more effectively and objectively. This paper presents an approach that integrates qualitative, social network analysis (SNA) and quantitative techniques for evaluating online collaborative learning interactions. Integration of various different data sources, tools and techniques provides a more complete and robust frame
How To Use GRID Technology for Building Next Generation Learning Environments
Grid technologies promise to improve the way we think about e-learning allow-ing wide-scale learning resources sharing in heterogeneous and geographi-cally distributed environments consenting, in this way, the implementation of distributed learning spaces where different organizations and individuals are able to cooperate in pursuing similar and complementary learning and training objectives. But is the e-learning ready for this evolution? In this paper we try, starting from an existing e-learni
Using Ontological Engineering to Overcome Common AI-ED Problems
This paper discusses long-term prospects of AI-ED research with the aim of giving a clear view of what we need for further promotion of the research from both the AI and ED points of view. An analysis of the current status of AI-ED research is done in the light of intelligence, conceptualization, standardization and theory-awareness. Following this, an ontology-based architecture with appropriate ontologies is proposed. Ontological engineering of IS/ID is next discussed followed by a road map to
Power Shift? The Rise of the Rest and the Decline of the West: facts, myths and economists [Audio]
Speaker(s): Professor Michael Cox | It has become the truism of our age that power is fast ebbing away from a declining West to the East and the "rest". Some indeed predict that the 21st Century will either be Asian or dominated by the so-called BRICs. But how far has this process really gone? Michael Cox is founding co-director of LSE IDEAS and professor of International Relations at LSE.
2014 Great Decisions Lecture: "China's Foreign Policy" by Dr. David Lai
As the dominant regional power in Asia, what does the rapid rise of this new superpower mean for other countries in the region and are there potential points of conflict with the U.S.
Segregated Schooling in Alabama

Group Seated Under a Canvas Awning
A group of people look at the photographer as they are seated under a makeshift canvas awning. The canvas is attached to the eave of a house. This could be for a family dinner as there are tables and chairs under the awning also.
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
Middle School Portal: Math and Science Pathways (MSP2)
SARS may currently dominate the headlines, but the Whyfiles takes another look at another fast-spreading viral disease: West Nile. West Nile has spread to 44 US states and beyond, and while it can be fatal to humans, it remains primarily a bird disease. The Whyfiles offers an in-depth exploration of West Nile in North American birds, tackling the questions How far? How fast? What's next? Who's next? The report also explains how researchers conduct bird studies, such as lab and field studies, ane
This extensive collection of activities from the American Museum of Natural History offers middle school students an exciting and creative context for involving students in the scientific process while introducing them to the rich diversity and beauty of their local ecosystem. Lesson plans, Web-based interactive activities, useful Web links, profiles of AMNH scientists and staff, and other features help students inventory and analyze the plants and arthropods found in their own neighborhoods. Al
This is an experiment showing the application of affinity chromatography to the separation of albumin from horse serum. A brief introduction of affinity chromatography and how it is being used in this specific experiment is given. This appears to be a good experiment to show the advantages of affinity chromatography in separating specific proteins from a complex matrix and would be useful in a biochemistry course or a course that is specifically looking at differing types of chromatography.

Auburn vs. Presbyterian (1944)
"Homecoming game found very little competition in Presbyterian College. Kuykendall and "Wormy" Ballard each scored three times to lead a 59-0 victory." (Description from 1945 Glomerata)
Give Your Car a Break
Over one week of homework activity, students complete two transportation surveys: the Give Your Car A Break - Trip Log and a Family Transportation Survey. At the end of the week students analyze their results to determine the potential for reducing greenhouse gas emissions through choosing alternative modes of travel to the single passenger car.
