Etude de connaissances d'élèves de seconde sur les mutations génétiques.
L'ADN est une notion qui pose problème aux élèves de lycée aussi nous nous proposons d'identifier et de classer les conceptions des élèves sur ce sujet.
Pour cette analyse, nous avons utilisé la notion de mutation, qui permet d'étudier à la
fois, comme nous le souhaitions, la structure et la fonction de l'ADN. Après avoir effectué une étude bibliographique et une analyse du savoir, nous avons cherché à vérifier l'existence de six niveaux biologiques dans les productions des élèv
Meeting the Challenges in Evaluating Mobile Learning: a 3-level Evaluation Framework
We propose six challenges in evaluating mobile learning: capturing and analysing learning in context and across contexts, measuring mobile learning processes and outcomes, respecting learner/participant privacy, assessing mobile technology utility and usability, considering the wider organisational and socio-cultural context of learning, and assessing in/formality. A three-level framework for evaluating mobile learning is proposed, comprising a micro level concerned with usability, a meso level
Workshop White Paper - Education in the Wild: contextual and location-based mobile learning in actio
The workshop explored recent innovations into location-based, or geospatially-informed, contextual mobile learning, and issues arising from them. Location-based technologies offer opportunities for new forms of learning that engage more deeply with physical surroundings and support continuity of understanding across settings; they also pose technical difficulties of modelling and maintaining continuity of context, and ethical challenges including the right to privacy of location and escape from
A Study of the Response to Accountability and Standardized Testing in a State University System: Pre
This study was an investigation of the perceptions of university certification officers in teacher education in a state university system regarding university responses to accountability, standardized testing, predictive models, gatekeeping, and intervention strategies, and incorporates the issues of social justice and ethics. This study also includes the development of a predictive model to predict results on the Praxis II Elementary Education: Curriculum Instruction and Assessment (ELED:CIA) t
From eLearning to eUniversity
This paper analyses the specifics and the tendencies in building the knowledge society as
well as the role of the universities in this process. Some European policies and programs dedicated to the
new role of the universities in realizing the Lisbon Strategy are analysed as well. It is emphasized on the
importance of integration of the ‘knowledge triangle’ (education, research and innovation) into a research
university and on the urgent need to re-design the university activities according to
MODELING CONCEPT DESIGN OF
INNOVATION PLATFORM
The transformation of the innovation processes is a fact and new forms of cooperation and partnership
among companies and research community emerge. The paper presents a model of concept design of

Social Software for Professional Learning:
Examples and Research Issues
Life-long learning is a key issue for our knowledge society. With social software systems new heterogeneous kinds of technology enhanced informal learning are now available to the life-long learner. Learners outside of learning institutions now have access to powerful social communities of experts and peers who are together forging a new web 2.0. This paper reviews current work in pan-European initiatives that impact upon life-long learning via views of professional learning, learner competence
Towards Web-Based Education of Demography
This paper describes steps taken towards introducing Web-based educational technology in teaching demography at the university level. Traditionally, demography is taught by giving lectures to the students, who are then expected to study from textbooks and exercise in demographic calculus. Some students find this way of learning monotonous and exhausting, hence their motivation gradually drops. Modern learning technology can help prevent such a situation, at least to an extent. Of course, using a
Mathematical Logic and Deduction in Computer Science Education
Mathematical logic is a discipline used in sciences and humanities with different point of view. Although in tertiary level computer science education it has a solid place, it does not hold also for secondary level education. We present a heterogeneous study both theoretical based and empirically based which points out the key role of logic in computer science, computer science education and knowledge representation. We focus on the key contrast of semantics and syntax, the resolution principle
Description et exploitations des traces du logiciel d’algèbre Aplusix
Cet article porte sur l’emploi de traces dans un contexte éducatif et sur leur utilisation dans un EIAH. La première partie présente le logiciel Aplusix, un micromonde pour l'apprentissage de l'algèbre qui permet l’enregistrement de productions d’élèves, comme celles obtenues dans l'environnement classique papier, mais comportant de plus d'autres informations, comme le temps, les hésitations, les corrections. Ce recueil produit une trace brute qui représente une modélisation comporte
Modélisation de profils d'élèves à partir de
traces de résolution de problèmes
La modélisation automatique des connaissances de l’apprenant est nécessaire dès lors que l’on cherche à accompagner un apprentissage dans le cadre des EIAH. Dans ce rapport, nous présentons un travail en cours dans lequel des techniques de classification automatique permettent d’engendrer des modèles d’élèves interprétables par un enseignant ou un didacticien et utilisables éventuellement par un « tuteur » automatique. L’approche proposée a été appliquée au domaine de la ré
New Distributed Research Practices and Scientific Immersion of Graduate Students with the Support of
MENTOR is a multidisciplinary research training program for graduate students in research field of mobility and posture disorders. Its members are distributed in a number of institutions across Montreal, creating challenges for the processes of collaborative research, joint supervision and scientific immersion. The purpose of our research project is to propose new distributed research and supervision practices supported by ICTs. In order to do this, we are designing a model of technological appr
Une approche pro-pédagogique du diagnostic cognitif dans les STI: conception, formalisation, et imp
In an Intelligent Tutoring System (ITS), issues related to the design and the implementation of the cognitive diagnosis (DC) of learner's behavior is addressed intuitively according to the specific goals of this STI. From a purely operational viewpoint, this approach is not really bad since the STIs arising from it, "work". However, when it comes to give to DC a pedagogical dimension in the human tutors, a look into perspective on more fundamental considerations promotes reflection in this direc
A Bayesian Student Model without Hidden Nodes and Its Comparison with Item Response Theory
The Bayesian framework offers a number of techniques for inferring an individual's knowledge
state from evidence of mastery of concepts or skills. A typical application where such a
technique can be useful is Computer Adaptive Testing (CAT). A Bayesian modeling scheme,
POKS, is proposed and compared to the traditional Item Response Theory (IRT), which has been
the prevalent CAT approach for the last three decades. POKS is based on the theory of
knowledge spaces and constructs item-to-item gra
