Students' activity in computer supported collaborative problem solving in mathematics
The purpose of this study was to analyse secondary school students' (N=16) computer-supported collaborative mathematical problem solving. The problem addressed in the study was: What kinds of metacognitive processes appear during computer-supported collaborative learning in mathematics? Another aim of the study was to consider the applicability of networked learning in mathematics. The network-based learning environment Knowledge Forum (KF) was used to support students' collaborative problem sol
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
Domain Modelling To Support Educational Web-based
This paper describes an approach to web-based authoring of educational material. We define a model for the class of subjects of our interest (those including both theoretical and practical issues). From this model, specific content outlines can be derived as subclasses and then instanced into actual domains. The last step consists in generating interactive documents, which use the instanced domain. Students can explore these documents through a web browser. Thus, an interactive learning scenario
Learning design based on graphical knowledge-modeling
This chapter states and explains that a Learning Design is the result of a knowledge engineering process where knowledge and competencies, learning design and delivery models are constructed in an integrated framework. We present a general graphic al language and a knowledge editor that has been adapted to support the construction of learning designs compliant with the IMS-LD specification. We situate LD within a taxonomy of knowledge models , namely the multi-actor collaborative system. We move
Web-based youth communities in the light of cyberspace psychology
The internet new media creates new types of communities - online or web-based communities in virtual reality. Everyone, to a certain degree, is involved in building and creating online communities. The main aim of this study is to make an overview of cyberspace technology and to extrapolate the influence of computers, technology and virtual environments on the psychology of Bulgarian students (individuals and groups). This study is focused on the chief features of web-based life in web-based com
Is There a Policy for Networked Learning?
Networked learning is part of an emergent networked society. As such networked learning forms part of a wider debate concerning the nature of social processes, power and culture and their relationships with technology. The literature surrounding networked learning still reflects a technological determinist view. This paper takes issue with this view of the relationship between technology and social forms. The context of higher education has been changing alongside the introduction of new technol
Is support really necessary within educational games?
Games can be powerful learning devices because of their interactive and multimedia capabilities, and their abilities to keep students motivated, active, deeply immersed and engaged for sustained periods of time. Yet the extent to which this translates into more effective knowledge and skill acquisition is not clear from the research reported so far. Several researchers have stressed that support tools should be added to game environments to ensure that learning takes place. In this paper we will
Interpreting Electrospray Mass Spectra
This site is a tutorial on interpretation of electrospray mass spectra of multiply charged molecules. It provides a simple explanation of the electrospray process and the potential for the creation of multiply charged species, especially when working with peptides. The mathematics of determining the charge state and molecular weight of the peptide is also explained. Although this site provides a good foundation on electrospray MS of peptides, students requiring an advanced understanding of MS
Uncertainty and Ambiguity in American Fiscal and Monetary Policies
Combining an historical approach with macroeconomic theory, Thomas Sargent will discuss ways of thinking about American fiscal and monetary policies - exploring how contradictions have developed and how they have been resolved. Thomas Sargent is professor of economics at New York University and senior fellow at Hoover Institution at Stanford University.

The Idea of Justice
Amartya Sen explores the ways in which, and the degree to which, justice is a matter of reason, and of different kinds of reason. This event marks the launch of Professor Sen's new book The Idea of Justice. Amartya Sen is Lamont University Professor at Harvard and an honorary fellow of LSE. He won the Nobel Prize in Economics in 1998 and was Master of Trinity College, Cambridge 1998-2004. His books include Development as Freedom (OUP), The Argumentative Indian (Allen Lane-Penguin) and Identity a
Nineteenth Century America in Art and Literature
In the United States, the nineteenth century was a time of tremendous growth and change. The new nation experienced a shift from a farming economy to an industrial one, major westward expansion, displacement of native peoples, rapid advances in technology and transportation, and a civil war. In this lesson, works of art from the nineteenth century are paired with written documents, including literary selections, a letter, and a speech. As budding historians, students can use these primary source
Environments of Africa
EARTH 105 investigates the interrelationships between geology, hydrology, land use and human development in several areas of Africa. We focus primarily on regions north of the equator, although there is a brife segment on South African mining. Specific topics include the Nile River (sources of the Nile, agricultural practices, effects of damming the Nile, and hydropolitics), the Sahara and Sahel (salt mines, climate change, drought, and wather resources), and natural resources and their role in

Adhesion of protective coating appliques on contaminated aluminum surfaces
The goal of this research was to develop an appliquÃ© system to protect an aluminum surface previously coated with a RTV silicone rubber. The appliquÃ© consisted of a poly (urethane) - based film coated with a suitable adhesive. Two adhesion problems were studied in this project: 1) adhesion to the contaminated aluminum surface, and 2) adhesion to the protective film of the appliquÃ©. Adhesion can occur according to several mechanisms: physical adsorption, chemical bonding, diffusion, elec
