PRAXIS - Pervasive Rehabilitation of Aphasia with an eXtensible Interactive System
This thesis describes computer-assisted (CA) methods for the treatment of acquired language impairment in adult aphasics. A key design objective of this project was the elimination of the indirect manipulation of keyboard and mouse (in CA speech language therapy sessions) in favour of the direct manipulation of virtual and physical objects afforded by touchscreen display and radio frequency identification technology (RFID). While computer-assisted treatment of aphasia has been used since the 196

Situational knowledge in physics: The case of electrodynamics
Major difficulties for a novice physics problem solver are how to interpret new problems and how to combine information given in the problem with information already known. A domain expert, by contrast, has the knowledge to take full advantage of problem features at a glance. It takes a long period of practice to acquire such situational knowledge, and it would be desirable for this to be taught more effectively. As a first step, this requires information on how situational knowledge differs acr

Physics learning with a computer Algebra systems: Towards a learning environment that promotes enhan
To become proficient problem-solvers, physics students need to form a coherent and flexible understanding of problem situations they are confronted with. This is important both for solving problems and for interpreting solutions. Still, many students have only a limited representation of the problems they are working on. Therefore, we devised an instructional approach to promote students' understanding of these problems, and to support them in forming associations between problem features and so

Co-Lab, design considerations for a collaborative inquiry learning environment
Co-Lab is a learning environment for collaborative inquiry learning in which learners can experiment, make models, consult background information and discuss their findings. The complex learning processes in such an environment need to be supported by appropriate features in the software. In this paper we report on how, based on existing literature and specific user and usability studies, we developed a set of design guidelines that were implemented in the software.

Contextualizing Discussions in Distance Learning Systems
In distance learning systems, communication tools are rarely integrated into learning activities, which does not encourage their use. The main goal of our work is to mitigate this lack of integration. Our aim is to bring the discussion activities closer to the learning activities, i.e. to situations to which the discussions must ideally relate to in order to promote learning between students. Thus, we suggest two models of forum which are contextual and based on a structuring of discussions resp

Using Case-Based Reasoning in Instructional Planning.Towards a Hybrid Self-improving Instructional P
This paper presents a new approach, based on the Case-Based Reasoning technique, which is useful to enhance Intelligent Tutoring Systems with learning abilities. Case-Based Reasoning is a recent paradigm for problem solving that has an inherent learning capability. So we integrate a Case-Based Instructional Planner within existing Intelligent Tutoring Systems (ITS) to enhance the pedagogical component with learning capabilities. In this way, the enhanced tutors combine the Case-Based Instruction

MArCo: Building an Artificial Conflict Mediator to Support Group Planning Interactions
The emphasis on building co-operative/collaborative environments has brought out the matter of group interactions. This, in its turn, has highlighted the issue of conflicts, inherent to group problem solving. If well employed, conflicts can act as triggers of cognitive changes, and thus help to refine the group's solution to the task. In this paper, we present a computational framework for detecting and mediating Meta-Cognitive conflicts. The theoretical framework presented here enables a comput

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.

The ZAP Project: Designing interactive computer tools for learning psychology
In the ZAP project, a set of interactive computer programs called 'ZAPs' was developed. The programs were designed in such a way that first-year students experience psychological phenomena in a vivid and self-explanatory way. Students can either take the role of participant in a psychological experiment, they can experience phenomena themselves, or they can take the role of researcher and learn by discovery. ZAPs provide added value to existing learning materials about psychological topics and c

Natural Editing of Algebraic Expressions
We call “natural editing of algebraic expressions” the editing of algebraic expressions in their natural representation, the one that is used on paper and blackboard. This is an issue we have investigated in the Aplusix project, a project which develops a system aiming at helping students to learn algebra. The paper summarises first the Aplusix project. Second it presents a notion of algebraic expressions, of representations of algebraic expressions. The last section develops ideas about natur

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

Supporting teachers when diagnosing their students in algebra
In this paper we will describe our current work on the Lingot project. We will focus on the description of a software called « Pépite », the objective of which is to help teachers diagnose their students' algebra competencies. Then we will show how different uses of Pepite by teachers lead us to define several types of diagnosis in order to fit better various users' needs.

Learning to Recommend from Positive Evidence
In recent years, many systems and approaches for recommending information, products or other objects have been developed. In these systems, often machine learning methods that need training input to acquire a user interest profile are used. Such methods typically need positive and negative evidence of the user's interests. To obtain both kinds of evidence, many systems make users rate relevant objects explicitly. Others merely observe the user's behavior, which fairly obviously yields positive e

Clustering Students to help Evaluate Learning
In this paper we show how clustering techniques can be applied to student answers generated from a web-based tutoring tool. In particular we are interested in extracting clusters of students based on the mistakes they made using the tool, with the aim of obtaining pedagogically relevant information and providing this feedback to the teacher. The data we used comes from the Logic-ITA, a web-based tutoring tool to practice formal proofs currently in use in the School of Information Technologies at

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).
