A Comparison of Model-Tracing and Constraint-Based Intelligent Tutoring Paradigms
Two approaches to building intelligent tutoring systems are the well-established model-tracing paradigm and the relatively newer constraint-based paradigm. Proponents of the constraint-based paradigm claim that it affords performance at levels comparable to that of model-tracing tutors, but with significantly less development effort. We have built both a model-tracing and constraint-based tutor for the same problem domain (statistical hypothesis testing) and report on our findings with the goals

The effects of graphical overviews on exploratory behaviour and knowledge acquisition in hypertext e
One of the main and recognized problems of learning with hypertexts is that learners are easily distracted and end up ‘lost in hyperspace’. As a result, they do not acquire complete and adequate knowledge. In this study, we enhanced a hypertext environment with a graphical overview that represented the basic structure of the domain and we designed the layout in such a way that learners were unobtrusively encouraged to follow a sequence of exploration that followed the domain structure. This so

Computational GRIDs and online laboratories
Many projects addressing the creation of online laboratories have been developed recently. They have a common goal: to enable students and professional learners to get hands-on experience without moving from the places where they are. Nevertheless, the found solutions are often very different among them, and interoperability between different online laboratories systems does not exist. In this paper we present our work around the exploitation of Grid technologies for sharing instrumentation and

Modélisation de profils d'élèves à partir de traces de résolution de problèmes
La modélisation automatique des connaissances de l’apprenant est nécessaire dès lors que l’on cherche à accompagner un apprentissage dans le cadre des EIAH. Dans ce rapport, nous présentons un travail en cours dans lequel des techniques de classification automatique permettent d’engendrer des modèles d’élèves interprétables par un enseignant ou un didacticien et utilisables éventuellement par un « tuteur » automatique. L’approche proposée a été appliquée au domaine de la ré

Proposal for convergence of e-learning systems for t-learning
This article presents considerations about viability on reutilize existing web based e- Learning systems on Interactive Digital TV environment according to Digital TV standard adopted in Brazil. Considering the popularity of Moodle system in academic and corporative area, such system was chosen as a foundation for a survey into its properties to create a specification of an Application Programming Interface (API) for convergence to t-Learning characteristics that demands efforts in interface des

Learning Bridges: a role for mobile technologies in education
A project called MyArtSpace, funded by the UK Department for Culture Media and Sport, is today exploring how children can engage in similar enquiry-led learning supported by mobile technology and how this can link to school and home learning. Using MyArtSpace as an example, we discuss the possibilities for mobile technology to form bridges between formal and informal learning. We also offer guidelines, drawn from our experience with MyArtSpace, for designing such bridges.

Using A Simulated Student for Instructional Design
In this paper, I describe how a cognitive model was used as a simulated student to help design lessons for training circuit board assemblers. The model was built in the Soar cognitive architecture, and was initially endowed with only an ability to learn instructions and prerequisite knowledge for the task. Five lessons, and a total of 81 instructions for teaching expert assembly were developed by iteratively drafting and testing instructions with the simulated student. The resulting instructions

Dialectics for collective activities: an approach to virtual campus design
This contribution is an attempt to systematise our approach to the design of a virtual campus. Activities in the recently started TECFA virtual campus rely on Internet tools, but they concern both distance teaching and presential interactions. Designing learning activities is relatively easy when the learning goal is an activity in itself. In this contribution, we explain how we extend the “learning by doing” approach to the acquisition of declarative knowledge. After fulfilling a pseudo-task,

From Mirroring to Guiding: A Review of State of the Art Technology for Supporting Collaborative Lear
We review a representative selection of systems that support the management of collaborative learning interaction, and characterize them within a simple classification framework. The 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 charact

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

Enabling Students to Construct Theories of Collaborative Inquiry and Reflective Learning: Computer S
To develop lifelong learning skills, we argue that students need to learn how to learn via inquiry and understand the sociocognitive and metacognitive processes that are involved. We illustrate how software could play a central role in enabling students to develop such expertise. Our hypothesis is that sociocognitive systems, such as those needed for collaborative inquiry and reflective learning, can best be understood as a community of interacting agents, who each have expertise in accomplishin

Scripting argumentative knowledge construction in computer-supported learning environments
Argumentative knowledge construction in computer-supported collaborative learning environments is often weak. This experimental study analyzes two collaboration scripts, which should facilitate argumentative knowledge construction. One script aims to support the construction of argumentation sequences and the other script aims to support the argument construction. These scripts should facilitate the argumentative knowledge construction on both the micro- and macrostructure of argumentation durin

Towards Comprehensive Space: A context for the programming/design of cybrids
Cybrids have been presented as mixed realities: spatial, architectural compositions comprised of physical and cyberspaces (Anders 1997). In order to create a rigorous approach to the design of architectural cybrids, this paper offers a model for programming their spaces. Other than accepting cyberspaces as part of architecture?s domain, this approach is not radical. Indeed, many parts of program development resemble those of conventional practice. However, the proposition that cyberspaces should
