From mirroring to guiding: A review of the state of art technology for supporting collaborative lear
We review systems that support the management of collaborative interaction, and propose a classification framework built on a simple model of coaching. Our framework distinguishes between mirroring systems, which display basic actions to collaborators, metacognitive tools, which represent the state of interaction via a set of key indicators, and coaching systems, which offer advice based on an interpretation of those indicators. The reviewed systems are further characterized by the type of inter

The defining characteristics of intelligent tutoring systems research: ITSs care, precisely
his paper argues that, despite the changes in philosophies and techniques that have occurred since ITS research began, there are continuous threads running through this research which define its essential and distinctive nature. In particular, ITSs are computer-based learning systems which attempt to adapt to the needs of learners and are therefore the only such systems which attempt to 'care' about learners in that sense. Also, ITS research is the only part of the general IT and education fie

Learning physics with a computer algebra system
To become proficient problem-solvers, physics students need to form a coherent and flexible understanding of problem situations with which they are confronted. Still, many students have only a limited representation of the problems on which they are working. Therefore, an instructional approach was devised to promote students' understanding of these problems and to support them in forming associations between problem features and solution methods. The approach was based on using the computer alg

Decentralized Service Deployment for Collaborative Environments
In this paper we present the design of a system which allows service deployment in a small-sized group of computers distributed through the Internet. These groups are formed by users who share a common interest, and voluntarily yield their own resources for the achievement of the collaborative activities of the group. Having enough resources contributed by the members of the group, our system guarantees service availability and the fact that the deployment and execution of the services is carrie

A Parallel Grid-based Implementation for Real Time Processing of Event Log Data in Collaborative App
Collaborative applications usually register user interaction in the form of semi-structured plain text event log data. Extracting and structuring this data is a prerequisite for later key processes such as the analysis of interactions, assessment of group activity, or the provision of awareness and feedback. Yet, in real situations of online collaborative activity the processing of log data is usually done offline since structuring event log data is, in general, a computationally costly process

Gridifying IBM's Generic Log Adapter to Speed-Up the Processing of Log Data
Problem determination in today's computing environments consumes between 30 and 70% of an organization’s IT resources and represents from one third to one half of their total cost of ownership. The first step to cutting down costs in this area and to enable autonomic computing systems is to have all parts of the system report status in a common log data format and semantics in order to be able to exploit the status information of the system as a whole. The Generic Log Adapter (GLA) is a generic

Efficient Embedding of Information and Knowledge into CSCL Applications
This study aims to explore two crucial aspects of collaborative work and learning: the importance of enabling CSCL applications, on the one hand, to capture and structure the information generated by group activity and, on the other hand, to extract the relevant knowledge in order to provide learners and tutors with efficient awareness and support as regards collaboration. To this end, we first identify and define the main types of information generated in online group activity and then propose

Normalising Geometrical Constructions: A Context for the Generation of Meanings for Ratio and Propor
This paper describes aspects of 13 year-olds’ activity in mathematics as emerged during the implementation of proportional geometric tasks in the classroom. Pupils were working in pairs using a piece of software specially designed for multiple representation (symbolic and graphical) of the variation in parametric procedures with dynamic manipulation of variable. In this paper we discuss children’s use of normalising, an activity in which children ‘correct’ the geometrical figures while devel

Shared conceptualisations in weblogs
In this paper we investigate how conceptualisations can be identified in weblogs using language technology (automated text analysis). We focus on getting a handle on both the concepts bloggers use and the way they think these concepts are related. The analysis of these conceptualisations can then be applied to a single weblog, resulting in a visualisation of potential conceptualisations the blogger wants to share with the outside world. Another type of analysis is to determine the overlap, or sh

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

CML - The ClassSync Modeling Language.
The ClassSync Modeling Language (CML) addresses the problem of creating a controlling overlay to classroom learning activities, or e-leaming workflows. Our aim is to allow authors and teachers to generate a mapping from activity design to its implementation in a wirelessly networked classroom with ubiquitous use of handheld computers for information exchange. CML models e-learning workflows with three major components: actors, data objects, and interaction networks. Actors are the diverse perfon

Addressing the Challenges of Inquiry-Based Learning Through Technology and Curriculum Design
Inquiry experiences can provide valuable opportunities for students to improve their understanding of both science content and scientific practices. However, the implementation of inquiry learning in classrooms presents a number of significant challenges. We have been exploring these challenges through a program of research on the use of scientific visualization technologies to support inquiry-based learning in the geosciences. In this article, we describe 5 significant challenges to implementin

Educational Software Components of Tomorrow (ESCOT)
Prior research and development demonstrates that dynamic notations and multiply-linked representations can enable ordinary students to achieve extraordinary learning of scientific and mathematical concepts (Kaput, 1992). However, prior techniques for building such software have resulted in expensive, incompatible, and inflexible products (Roschelle & Kaput, 1996). The vast majority of educational software projects, many of which are funded by the public sector, show promising results in small te

Uncertainty-reducing cooperation scripts in online learning environments
Online learning courses can create new interaction situations for participants who have not previously worked with each other. Initially, there is some degree of uncertainty between participants in these interaction situations. According to the uncertainty reduction theory, low uncertainty increases theamount of discourse and decreases information seeking. Thus, uncertainty may influence online discourseand learning. However, the relation of uncertainty reduction to learning outcomes has not yet
