An Algebra Subsystem for Diagnosing Students' Input in a Physics Tutoring System
To help a student in an introductory physics course do quantitative homework problems, an intelligent tutoring system must determine information of an algebraic nature. This paper describes a subsystem which resolves such questions for Andes2. The capabilities of the subsystem would be useful for any ITS which deals with problems involving complex systems of equations. This subsystem is capable of 1) solving the systems of equations at the level of introductory physics problems, 2) checking the
Quelle est la nature des expériences vécues par les étudiants en Travaux Pratiques : analyse de d
Le but de cet article est de faire le lien entre les expériences vécues par des étudiants durant les TP et les activités conçues et décrites par lenseignant. Nous tentons donc de déduire la nature des expériences dapprentissage vécues par les étudiants en TP, à partir du discours des enseignants sur ce quils font et ce quils demandent aux étudiants de faire. Nous introduisons un cadre théorique que nous utilisons pour caractériser des Travaux Pratiques : selon leurs buts et
Self-directed learning in simulation-based discovery environments
SIMQUEST1 is an authoring system for designing and creating simulation-based learn-ing environments. The special character of SIMQUEST learning environments is that they include cognitive support for learners which means that they provide learners with support in the discovery process. In SIMQUEST learning environments we try to find the balance between direct guidance of the learning process and sufficient free-dom for learners to regulate the learning process themselves. In this article we de-
Students' adaptation to a new situation:
the design of an experimental procedure
Different studies (Arce and Betancourt, 1997; Séré, 2002) emphasize the importance of the task of experimental procedure design in a learning context. However, the required design is a difficult task for students (Séré and Beney, 1997). Consequently, students are hardly ever allowed to design their own experiment. The study by Tiberghien et al. (2001) showed that to learn how to plan an investigation in order to address a specific question or problem was the least frequent process object
Effects of pictures, age and experience on learning to use a computer program
This study examines the effects of pictures of screen captures and input devices on documentation for older novices. There was no main effect of pictures, but there were statistically significant interactions between the type of picture and the factors of age and computer experience. As predicted, the most optimized designsthe ones presenting screen capturesmoderated the negative effects of age. We argue that screen captures help reduce two problems in the cognitive area that are especially

New authoring frameworks for integrating collaborative learning technologies
This workshop is intended for CSCL researchers and/or their technologists who are interested in designing and then actually creating rich, interactive learning materials in a technology-enhanced environment. The workshop will present the work of two complementary approaches to the design of environments for collaborative, productive and open ended learning, such as collaborative inquiry learning and learning by design. Participants bring in their own issues and work on the design of learning env
Learning Design Repositories Structure Ontology and Processes
We summarize here the results of a project called IDLD: Implementation and Deployment of the Learning Design specification. The main product of the IDLD project is a portal that provides a suite of tools and methodological aids to help build IMS-LD compliant learning designs. In this paper, we focus on a practical approach to build and extend a repository of learning designs. We present a more specific process where tools in the portal serve to extend the repository by building LD patterns extra
Emergence de Diagnostic par Formation de Coalitions - Application au diagnostic des conceptions d'un
Cet article présente une approche d'une tâche de diagnostic basée sur la formation de coalitions. Nous considérons le diagnostic comme étant le résultat émergent de l'activité interactive d'agents d'un niveau micro, résultat qui est interprété par des agents spécialisés d'un niveau supérieur (niveau macro). Au niveau micro, les agents interagissent et, suite à un processus de vote, forment des coalitions; au niveau macro, les agents spécialisés sont capables d'interpréter les c
A Snail Mail In-Basket Gets a Delivery Update
For years, principal pre-service programs have employed in-basket simulations to provide learning experiences that reflect the realities of a school administrator's work day. In-basket exercises afford graduate students opportunities to explore such leadership skills as organizing and prioritizing tasks, managing time, making decisions, taking initiative, practicing interpersonal skills, delegating responsibilities, and monitoring and following up on actions (Nowack, K. M., 1993). In order to re
A Multidimensional Approach To Educating All Children: Empowering Stakeholders To Make Appropriate D
This conceptual paper diagnoses the limitations and historic misuses of Deno’s Cascade Model for students with special needs and proposes a new schema for the individualized inclusion of all students. The extension of a once simplistic model is viewed through the triangulated perspectives of (1) students’ understanding and attitude; (2) parental care and advice; (3) teachers’ conscientious behaviors; and (4) administrative leadership. We propose a comprehensive placement option for student
Video-as-Data and Digital Video Manipulation Techniques for Transforming
Learning Sciences Research,
This chapter concerns the theoretical and empirical foundations and current progress of the Digital Interactive Video Exploration and Reflection (DIVER) Project at Stanford University. The DIVER Project aspires to accelerate cultural appropriation of video as a fluid expressive medium for generating, sharing, and critiquing different perspectives on the same richly recorded events and to work with others to establish a Digital Video Collaboratory (DVC) that enables cumulative knowledge building
Exploratory and Experimental Learning? For Teachers and Researchers tool
The term exploratory learning usually denotes some type of activity used by students, with or without a teacher's supervision, to facilitate the learning and mastery of a predefined and relatively circumscribed domain. That exploration may be more or less guided, according to the domain structure and the teacher's pedagogical goals and strategies. But there is also another way to use exploratory and even experimental learning, which may be used inside or outside an educational setting: rathe
Students will use a game and a discussion to demonstrate the importance of artifacts in context for learning about past people.
SEXTANT, un langage de modélisation des connaissances pour la navigation textuelle
Nous présentons tout d'abord notre conception de la navigation textuelle conçue comme un processus cognitif qui convoque des connaissances qui sont propres à la finalité de la navigation. Nous formulons l'hypothèse que ces connaissances peuvent être, en partie, modélisées sous une forme déclarative avec le langage SEXTANT que nous décrivons. Enfin, nous présentons deux applications qui utilisent la plate-forme NaviTexte dans laquelle le langage SEXTANT est implémenté.,Proceedings wi
