An adaptive learning environment in DICE system with TDD model
We introduce an adaptive learning environment named DALM (DICE adaptive learning model) based on DICE test-driven development (TDD) model that was implemented in a parse-tree based automatic on-line grader. In our opinion, there are three variables in DALM. The individual differences (I) classify the learners into several groups. The training method (T) that equivalent to TDD model in DICE can be controlled by DICE system. The learning outcome (O) presents the learning performance of learners wi

Le travail présenté a été effectué dans le cadre de la validation d'un système expert en santé animal développée par l'INRA. Les conceptions d'éleveurs sont analysées en situation de résolution de problème en élevage porcin afin de les confronter avec celles formalisées dans le système expert porcidact.
Analyzing Sequential Data in Computer-Supported Collaborative Learning
Representations and changes between them play a major role in cognitive development (e.g., Vosniadou, & Brewer, 1992) and education (e.g., Hewson, Beeth, & Thorley, 1998). By definition, change of representations is also indispensable for collaborative work since a common understanding or shared knowledge can only be achieved by a partial convergence of the knowledge structures of the collaborating subjects. This articles presents and discusses knowledge tracking (KT), viz., an approach to analy
Capitalisation dune ressource en or : le dictionnaire
The goal of this paper is to explore extensions to electronic dictionaries. Adding certain functions could considerably extend the range of tasks for which they could provide support. Putting the needed information at the distance of a mouse click would allow for active reading. This would require tight coupling of the dictionary with a text editor: all the information in the dictionary should be accessible via a mouseclick. Dictionaries combined with a flashcard system and an exercise generator
Bridging the Contextual Distance: The e-CASE Learning Environment for Supporting Students Context
Supporting students awareness of the complex way that contextual issues affect knowledge application in authentic situations is a critical instructional mission and can lead to improved problem solving in the workplace. In this work we present the design of e-CASE (Context Awareness Supporting Environment), which is a case based learning environment for supporting instruction in the domain of software development. In designing e-CASE we employ a model for context which further guides the use o
Mixing Human and Software Agents: A Case Study
This paper describes a multi agent approach of the organisation of a collective activity within a pedagogical context. We consider pedagogical situations where students have to explicitly define the articulation of their collective work and then achieve the different tasks they have defined. Our objective is to support these students by taking some of these tasks in charge whilst making them work out such organisation features. For this purpose, we propose to consider that the group of students
Dialogue in context, towards a referential approach in collective learning
In this article, we present research in the making of a collective work environment within the framework of a distance education course. We base our theoretical and methodological standpoints on examples of dialogical discourses recorded within the framework of this CSCL system called Symba. In fact, the results of previous research lead us to rethink our vision of the study of collaborative moments between participants in a computer-supported human learning environment that proposes several com
Using e-mail to support reflective narration
This article presents an exploratory study of e-mail use for reflective narration. Narration is viewed from three perspectives: the narrating act, the narrative statement, and the story. These perspectives are used to characterize the 69 e-mails that were exchanged between 13 groups of children from three primary schools. The findings show that e-mail narration has monologic and dialogic qualities, and leads to cognitive and personal reflections on the learning task. We conclude that e-mail can
Progressive computer-supported modelling as a learner activity: A tool for understanding
Recently, computer modelling has been added as a new topic in final examination programmes for physics and mathematics in the Netherlands. It involves constructing, running, evaluating, and extending simulation models. Currently, we are developing curriculum materials to support this new topic. In the course of our work, we became convinced that computer-supported modelling should be an integrated part of the curriculum from early on. Constructing a model involves identifying components, propert

Providing Efficient Event Information Management to CSCL Applications
This work aims to explore the importance of carrying out an efficient management of the event information generated from CSCL applications during the collaborative learning process. The achievement of this task first involves the design of a conceptual model of collaborative learning interaction that captures and distinguishes several high-level collaborative learning processes, which in turns leads to a computational model. To achieve that, we first define the main types of event information ge
Problems and Opportunities of Learning together in a Virtual Learning Environment
This chapter explores new ways of collaborative learning in a virtual learning environment based on our acquisition of knowledge from previous experience. We identify both the problems faced in real collaborative learning practices and the ways these problems can be overcome and become opportunities for more efficient learning. These issues concern pedagogical, organisational and technical elements and constraints that influence the successful application of collaborative learning in distance ed
Improving database design teaching in secondary education: action research implementation for docume
Database design and use has educational interest for utilitarian and learning reasons. Database technology has significant economic impact and the demand for database design can not be covered by the existent educated experts. Furthermore the database management systems available at schools could be used for the design and implementation of high quality learning activities. Databases are general
purpose modeling environments that enable problem solving using conceptual frameworks closer to the s
Scripting argumentation in technology enhanced learning: a proposed system architecture
Argumentative knowledge construction is an important component of critical thinking. Learners who collaboratively argue about a subject can potentially develop domain knowledge and have the opportunity to use evidence critically in order to make sense of the subject under consideration. Moreover learners have to take into account claims and evidence of each other during argumentation and in this way they develop mental models for argument construction and sequence. However, research indicates th
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

Enhancing Fourth Graders Ability to Interpret Graphical Representations Through the Use of Microco
This article reports on a research effort that investigated whether the use of Microcomputer-Based Labs (MBLs), implemented within an inquiry-based activity sequence on phase transformations (melting and freezing), contributes to the development of fourth grade (9-10 year-old) students conceptual understanding and ability to construct and interprete graphs. The participants of the study were 65 fourth graders (organized into an experimental and two control groups). The experimental treatment i
Bridging the Gap Between Empirical Data on Open-Ended Tutorial Interactions and Computational Models
In this paper we present an approach to using empirical data on human teacher-learner interactions to guide the development of a pedagogical agent for supporting musical composition learning. Our approach to bridging the gap between tutorial interaction analysis and computational models, intended for use in learning support systems, is a new one. We support our claim by pointing out that most of the previous work in the area of using human tutors as models has been conducted in domains that are
Supporting Social Interaction in an Intelligent Collaborative Learning System
Students learning effectively in groups encourage each other to ask questions, explain and justify their opinions, articulate their reasoning, and elaborate and reflect upon their knowledge. The benefits of collaborative learning, however, are only achieved by active, well-functioning teams. This paper presents a model of collaborative learning designed to help an intelligent collaborative learning system identify and target group interaction problem areas. The model describes potential indicato
