MemoNote, un outil de gestion des connaissances personnelles pour enseignants à base d’annotation
Cet article vise à proposer un outil de gestion des connaissances personnelles (PKM) à base d’annotations, MemoNote, dédié à l’enseignant considéré comme un travailleur intellectuel. Me-moNote utilise l’activité annotation de l’enseignant pour mémoriser sa conception per-sonnelle du document en particulier aux niveaux pédagogiques et domaine, qu’il pourra réutiliser par la suite. Cet article identifie les trois dimen-sions nécessaires à l’annotation dans un tel outil de
Semantic annotation for the teacher: models for a computerized memory tool
This article aims to propose a model of semantic annotation dedicated to the teacher. This model must adapt to the teacher’s activity specificity, who needs to master both a pedagogical and domain expertise. In this paper, we analyze the particularity of the teacher’s annotation language that enables the teacher to express his own expertise. First, we identify the concepts of this annotation language used by the community of teachers. Then we propose a conceptual model of this language base
MemoNote, an annotation-based personal knowledge management tool for teachers
This article aims to propose a personal knowledge management tool based on annotation, MemoNote, dedicated to teacher. The teacher is considered as a knowledge worker. MemoNote makes use of the teacher's annotation activity to memorize his/her personal conception about the document content, (in particular the domain and the pedagogy knowledge). This paper identifies three general requirements for the annotation object in such a tool to enable the teacher to manage his/her document-related person
Using and modeling context with ontology in
e-learning: the case of teacher’s personal annotation
This article aims at defining a context ontology of teacher’s personal annotation, in order to use it in a context-aware annotation tool “MemoNote”. Starting from a general definition of the context and its application to teacher’s annotation, we define the uses of active and passive contexts in MemoNote (annotation ontologies selection, annotation memorization, pattern definition and selection). We then develop completely teacher’s annotation context annotation ontology using the clas
PDAs and Handhelds: ICT at your side and not in your face
This paper stems from a trial at the Graduate School of Education in the University of Bristol supported by the Training and Development Agency for Schools (TDA) and set up to evaluate the potential of personal digital assistants with internet access to support initial teacher training (ITT) students in science. Fourteen students were given PDAs selected to represent the range of then currently available PDAs with mobile phone connectivity in the UK. As a result the following areas were identifi
A computer program for the learning of algebra: description and first experiment
We present APLUSIX, a computer system that helps students to learn algebra, available at http://aplusix.imag.fr. APLUSIX contains an advanced 2D editor of algebraic expressions that allows students to make the calculations (s)he wants, like in a paper-pencil context. The system verifies the student's calculations, by calculating the equivalence between two consecutives expressions, and shows the result to the student. It provides information concerning the progress of the resolution. Furthermore
The roles of models in Artificial Intelligence and Education research: a prospective view
In this paper I speculate on the near future of research in Artificial Intelligence and Education (AIED), on the basis of three uses of models of educational processes: models as scientific tools, models as components of educational artefacts, and models as bases for design of educational artefacts. In terms of the first role, I claim that the recent shift towards studying collaborative learning situations needs to be accompanied by an evolution of the types of theories and models that are used,
A model for negotiation in teaching-learning dialogues
Despite the fact that a number of researchers from a wide variety of theoretical perspectives have claimed that negotiation in dialogue is fundamental in learning, little research has been based on a precise notion of what negotiation is and how it relates to learning. This paper describes a model for negotiation, based on analysis of teacher-student and learner-learner dialogues. After discussion of illustrative examples and review of related research, negotiations are defined in terms of four
An integrated perspective to approach technology in mathematics education
This paper concerns a research work developed in an European project. The aim of this work was to produce a document integrating the different theoretical frameworks employed by the project teams. The theoretical constructs of didactical functionalities, and experimental educational cycle, associated to an ICT tool, allowed us to analyse the roles played by technology in the considered set of theoretical frameworks. With this respect, we present examples concerning the theory of didactic situati
Incorporating e-learning into a Local Government Authority Context: Evaluating Developers' Perspecti
In this paper, we describe the evaluation of an e-learning project. The Learning Ladder developed a number of elearning modules for local government staff on recurrent working practices. The modules feature the use of short video clips as a means to support and encourage organisational learning. We report on one part of the evaluation: namely, the qualitative analysis of data from developers. We focus on three aspects: developers perceptions of video clips for learners to reflect upon example
Learning design based on graphical knowledge-modeling
This chapter states and explains that a Learning Design is the result of a knowledge engineering process where knowledge and competencies, learning design and delivery models are constructed in an integrated framework. We present a general graphic al language and a knowledge editor that has been adapted to support the construction of learning designs compliant with the IMS-LD specification. We situate LD within a taxonomy of knowledge models , namely the multi-actor collaborative system. We move
Évaluer l'utilisation d'hypermédias : intérêts et limites des variables de performance
Two main levels in describing hypermedia use can be distinguished. At a global level, the general purpose can be described in terms of learning or problem solving. At a more local level, specific goals can be described in terms of the learners' activity with the system, i.e. the visiting of one or more information nodes. In this paper, the influence of the nature of these local goals on performance variables such as recall, precision, and economy of hypermedia use are investigated. Specific char

This lesson describes the major components and functions of the immune system and the role of engineers in keeping the body healthy (e.g., vaccinations and antibiotics, among other things). This lesson also discusses how an astronaut’s immune system is suppressed during spaceflight due to stress and other environmental factors.
Out of Breath
This lesson goes over the parts of the human respiratory system and the gas exchange process that occurs in the lungs. It also covers changes in the respiratory system that occur during spaceflight, such as decreased lung capacity.
Just Passing Through
This lesson helps students explore the functions of the kidney and its place in the urinary system. Students learn how engineers design instruments to help people when kidneys are not functioning properly or when environmental conditions change, such as kidney function in space.
Unlocking the Endocrine System
Students learn how the endocrine system works and compare it to the mail delivery system. Students discuss the importance of communication in human body systems and relate that to engineering and astronauts.
The Heart of the Matter
This lesson describes how the circulatory system works, including the heart, blood vessels and blood. Students learn about the chambers and valves of the heart, the difference between veins and arteries, and the different components of blood. This lesson also covers the technology engineers have developed to repair the heart if it is damaged. Students also understand how the circulatory system is affected during spaceflight (e.g., astronauts lose muscle in their heart during space travel).
Læring i praksis - fremstruktureringen af et
Introduktionen præsenterer afhandlingens emnemæssige baggrund, problemformulering og metode. Den traditionelle angelsaksiske erkendelsesteoretiske opfattelse af viden hævdes at have komplementære modpoler i læringsteorierne behaviorisme og kognitivisme. Disse positioner problematiseres med eksempler fra hverdagsmæssige sammenhænge såvel som med en række forskningsmæssige resultater. På baggrund heraf fremsættes problemformuleringen, som lyder: Er det muligt at udvikle et begreb om vi
