Building theories: working in a microworld and writing the mathematical notebook
In the framework of a long term teaching experiment we present an Educational approach based on the use of a dynamic geometry software and a symbolic manipulator. Here we present the general ideas of the followed approach focusing on how meanings can originate from phenomenological experience and evolve under the guidance of the teacher. In particular we will focus on meanings related to the ideas of theory, axiom and theorem.
Computer-Supported Scripting of Interaction in Collaborative Learning Environments: Framework on mul
Collaboration scripts aim to facilitate effective interaction patterns for collaborative learning that do not occur spontaneously. So far, diverse non-generic scripts have been conceptualized and investigated in CSCL environments. The specification of collaboration scripts aims to provide a common terminolgy for describing scripts and to abstract the core design principles of scripts to better understand effects and mechanisms of collaboration scripts and to apply and re-apply collaboration scri
Adaptive learning scenarios for detection of misconceptions about electricity and remediation
Our main objective is to model the knowledge used by learners in order to solve problems about electricity. We are searching means to do a diagnosis about student's activity based on a microworld of electric circuits. Once the diagnosis realized, we try to provide the learner with the most relevant remediation with regard to his/her misconceptions.
TéléCabri, un environnement pour le préceptorat à distance.
L'objectif du projet TéléCabri est de contribuer à la solution de ces problèmes en apportant des moyens complémentaires de l'action humaine pour assurer la continuité de la scolarité pendant l'hospitalisation des enfants ou adolescents. TéléCabri doit apparaître comme une machine partenaire de l'élève autant que de l'enseignant. En intégrant la téléprésence et des fonctionnalités de coopération dans un environnement informatique pour l'apprentissage humain.
Networked Learning, a relational approach weak and strong ties.
In this paper, we explore the idea of weak ties in networked learning. We go back to the original conception of the strength of weak ties (Granovetter 1973) and relate this to a dialogic understanding of networked learning (Koschmann 1999, Dysthe 2002). These theoretical ideas are applied to the examination of two networked settings in which educational leaders exchange ideas and have the potential to create knowledge. We examine these networks from the point of view of the overall pattern of in
EMLs : case study in distance learning education
After a short characterization of what an educational modeling language should be, we will deal with the respective interest of two EML proposals : one proposed by OUNL (OUNL/EML and IMS/LD which is derived from it) and one proposed by UNED (PALO). We will then identify reasons that lead us to choose OUNL/EML for experimentation in distance learning education in order to model our scenario. Finally we will present some limitations or extensions we have identified.
Understanding the structure of the set of rational numbers: a conceptual change approach.
In the present article, we argue that the conceptual change approach to learning can apply in the case of mathematics, taking into consideration the particular nature of mathematical knowledge and the neurobiological bases of mathematical cognition. In the empirical study that is reported in this article, we investigated ninth graders' understanding of algebraic and structural properties of rational numbers, from a conceptual change perspective. We make the point that understanding rational numb
Literature Review in Informal Learning with Technology Outside School
When we think about learning, we often tend to think about schools, universities, colleges. If we go a little further and think about learning outside school, we might begin to consider museums, galleries and science centres. What we often tend to overlook, however, is the sort of learning that goes on as part of our normal day-to-day activities when we don't even think we are learning. Today, however, anyone who has an interest in how children learn with digital technologies needs to look beyon
Teaching Expertise is at The Core of ITS Research
To design efficient, flexible and user-adaptable learning environments, we need to embed a great deal of knowledge into them. This paper emphasises the teacher's knowledge, which encompasses all the expertise of the teacher or of the trainer. Thus it is broader than that which is usually called tutoring knowledge. We start with a description of several facets of teaching expertise and of various implementations that have been described in the ITS literature. Then we describe in more detail some
The effect of collaborative knowledge modeling at a distance on performance and on learning
This study examines the effect of co-elaborating a knowledge model in dyads at a distance on performance and on learning. Forty-eight adults participated in the study. Participants were trained to re-represent knowledge taken from a text, using an object-typed knowledge modeling editor software tool. Knowledge modeling is similar to concept mapping, except that the former is based on a typology of knowledge objects and a typology of links, and that the structure of the knowledge representation i
Socio-cultural Perspectives on Object-oriented Learning
One of the central objectives of project COOL is to explore critical aspects associated with learning (and teaching) object-oriented concepts. This objective will be pursued by bringing forth the heritage of Kristen Nygaard and the Norwegian approach to object-orientation. The project will develop learning material based on this work and intends to make the material available to the object-oriented community in the form of reusable learning objects. This paper explores how social-cultural theori

E-university – what have we learned?
Enforcing Cooperative Storytelling: First Studies
In this paper, we describe the first prototype of a system called StoryTable, aimed at supporting a group of children in the activity of storytelling. The system is based on a special multi-user touchable device (the MERL DiamondTouch) and it was designed with the purpose of enforcing collaboration between children. The paper discusses how the main design choices were influenced by the paradigm of cooperative learning and presents two observational studies to assess the effects of the different
A Plug-In Architecture for Graph Based Collaborative Modeling Systems
This paper presents ongoing work on a graphical modeling and discussion support system. One of the properties of the presented approach is that it tries to implement a "collaborative mind tool" approach, bridging the gap between a communication means and a system with AI functionality. The paper also points out the XML based plug-in mechanism of the system and illustrates it by several categorized examples.

Grounding is not shared understanding : distinguishing grounding at an utterance and knowledge leve
This paper argues that for the study and facilitation of collaborative learning, existing theories of grounding such as that of Clark and Shaefer  cannot be applied without adjustments. When comparing collaborative learning and conversation, four dimensions can be identified where grounding at a knowledge level differs from the grounding at an utterance level. Firstly, the indirect access and the existence of a range of manifest meanings, poses the need for a notion of groundedness'. Second
This is an experiment showing the application of affinity chromatography to the separation of albumin from horse serum. A brief introduction of affinity chromatography and how it is being used in this specific experiment is given. This appears to be a good experiment to show the advantages of affinity chromatography in separating specific proteins from a complex matrix and would be useful in a biochemistry course or a course that is specifically looking at differing types of chromatography.
The Electronic Statistics Textbook
This electronic textbook on statistics provides both extensive and in depth coverage of statistics. Although an excellent reference for analytical chemistry students and faculty, the lack of chemistry-related practice problems or exercises may not make it an appropriate substitute for a traditional text.
