Un modèle informatique de scénario fondé sur des pratiques réelles d'enseignement et une théori
La conception de scénarios pour un EIAH nécessite la mise en oeuvre de théories didactiques, de pratiques réelles, de modèles et de théories informatiques afin de prendre en compte les contraintes didactiques nécessaire à la modélisation de scénarios d'apprentissage. La modélisation de scénario devient ainsi une problématique pluridisciplinaire. La contribution principale de cet article est de proposer un modèle informatique de scénarios prenant effectivement en compte des contrai
A Didactic-based Model of Scenarios for Designing an Adaptive and Context-Aware Learning System
Nowadays, technology-enhanced learning systems must have the ability to take into account the context and to allow dynamic adaptation to different learners based on substantial advances in pedagogical theories and knowledge models. The main issue is to design a generic scenario which can deal with the broadest range of learning situations. From a generic scenario, the learning system will compute on the fly a particular scenario dedicated to the current learner and its learning situation. The ma
Towards a classification of Narrative Learning Environments
In this paper, we highlight why narrative can support learning, drawing from the literature. Then we describe what are NLEs, mentioning a few examples. We also discuss NLEsÂ’ characterizing aspects - user role, technological means and educational approach - stressing their importance in determining the learning afforded by an environment. We conclude by pointing out what issues need to be tackled to advance the field.,Research report
Supporting information comparisons in example-based hypertext environments
Global comparisons of learning from hypertext and traditional text have yet failed to show major advantages concerning the effectiveness of hypertext learning. In the current paper it is proposed that an effective hypertext design needs to be based on thorough cognitive task analyses with regard to structures, processes, and resources that are required to benefit from a specific learning approach. This claim is illustrated by two experiments, in which we investigated two methods for supporting e
Reducing cognitive load and fostering cognitive skill acquisition: Benefits of category-avoiding exa
In this paper, we provide evidence against the common idea that worked examples should be designed to convey problem categories and category-specific solution procedures. Instead we propose that instructional examples should be designed in a way that supports the understanding of relations between structural problem features and individual solution steps, i.e. relations that hold below the category level. We illustrate in the domain of probability word problems how category-avoiding instructiona
A Programming by Demonstration Authoring Tool
for Model-Tracing Tutors
Model-tracing tutors have consistently been among the most effective class of intelligent learning environments. Across a number of empirical studies, these tutors have shown students can learn the tutored domain better or in a shorter amount of time than traditionally taught students (Anderson et al., 1990). Unfortunately, the creation of these tutors, particularly the production system component, is a time-intensive task, requiring knowledge that lies outside the tutored domain. This outside k
Anchored Interactive Learning Environments
Advances in computer technology and multi-media systems have led to widespread interest in computer-based instruction and learning environments. The use of video, animation, graphics, and simulation allow the presentation of material in realistic contexts, thus addressing the problems of inert knowledge while promoting constructive and generative learning. But the true potential and benefits of these systems are yet to be realized. Cognitive studies on learning and transfer suggest that concepts
Intelligent Tutoring Goes To School in the Big City
This paper reports on a large-scale experiment introducing and evaluating intelligent tutoring in an urban High School setting. Critical to the success of this project has been a client-centered design approach that has matched our client's expertise in curricular objectives and classroom teaching with our expertise in artificial intelligence and cognitive psychology. The Pittsburgh Urban Mathematics Project (PUMP) has produced an algebra curriculum that is centrally focused on mathematical anal
Exploring the Design of Computer Supports for Reciprocal Tutoring
his paper explores the design of a set of system prototypes for supporting a protocol of cooperative learning activity called reciprocal tutoring. During reciprocal tutoring, two or more agents in centralized or distributed environments interact as they take turns at playing the roles of a tutor and a tutee in solving Lisp recursive problems. These agents are either real students or virtual learning companions simulated by the computer. Furthermore, in the design of a virtual tutee, which is one
Task and Interaction Regulation in Controlling a Traffic Simulation
In collaborative problem solving, metacognition not only covers strategic reasoning related to the task but also reasoning related to the interaction itself. The hypothesis underlying this work states that regulation of the interaction and regulation of the task are closely related mechanisms and that their co-occurrence facilitates collaborative problem solving. These assumptions are tested experimentally with a traffic simulator. The results show that co-occurrence of task and interaction regu
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 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
Can learning from molar and modular worked examples be enhanced by providing instructional explanati
In two experiments we explored how learning from traditional molar worked-out examples—focusing on problem categories and their associated overall solution procedures—as well as from more efficient modular worked-out examples—where intrinsic cognitive load is reduced by breaking down complex solutions into smaller meaningful solution elements—can be further enhanced. Instructional explanations or self-explanation prompts were administered to increase germane cognitive load. However, both int
A Framework System for Intelligent Support in Open Distributed Learning Environments
Recent trends in the design of learning support systems are characterized by considering group interaction, by combining intelligent support with interactive learning environments, by providing reusable domain-independent components, and by using agent-structured architectures. Taking these trends into account, an open framework system has been developed for integrating distributed intelligent support components with an interactive and collaborative learning environment. Work in shared activity
Computer Software Support for Collaborative Learning
In this chapter, we discuss two approaches to supporting collaborative learning activities in higher education through technological means: structuring and regulating collaboration. Structuring approaches aim to create favorable conditions for learning by designing and scripting the situation before the interaction begins. They attempt to define the structure of the learning experience by varying the characteristics of the participants (e.g. the size and composition of the group, or definition a
Elaborating new arguments through a CSCL scenario
The CSCL community faces two main challenges with respect to learning and argumentation. The scientific challenge is to understand how argumentation produces learning, that is to discover which cognitive mechanisms, triggered by argumentative interactions, generate new knowledge and in which conditions. The engineering challenge is to determine how to trigger productive argumentation among students. These two challenges are often investigated in parallel, but this contribution focuses on the lat
Learning to collaborate: Designing collaboration in a 3-D game environment
To respond to learning needs, Computer-Supported Collaborative Learning (CSCL) must provide instructional support. The particular focus of this paper is on designing collaboration in a 3-D virtual game environment intended to make learning more effective by promoting student opportunities for interaction. The empirical experiment eScape, which encourages learners to solve problems collaboratively, is also presented. eScape is a design experiment, comprising both the process of designing a collab
Training strategies and knowledge acquisition: Using the same reflective tools for different purpose
The Emma educational system embodies a Knowledge Based System (KBS) that models a problem-solving method defined at an abstract level. In order to allow different explicit problem-solvings, the KBS is based on a Task-Method modelisation. The objectives of this paper are (1) to explain how we take advantage of the flexibility provided by the modelisation by using analysis-modules that can study what the influence of the student's propositions on the rest of the solving is; (2) to highlight that e
Enhancing a Web-Based Distance-Learning Curriculum with Dedicated Tools
The work presented in this paper aims at supporting students involved in a Web-based distance-learning curriculum. For such a purpose, the Saafir system proposes students with different tools that support them in their appropriation of this curriculum, e.g. visualization of the curriculum from different points of view or construction of individual projects by putting different items of the curriculum into relation. In order to allow using Saafir with already existing distance-learning Websites,
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
