User modeling is the core component for the majority of personalization services. It has become an important factor in the effort to personalize a diversity of Web resources according to userspsila characteristics and needs. While trying to move a step further and model dynamic users in a range of contexts, life-long user modeling, the ability to model a dynamic and changing user throughout lifetime...
We present in this paper a computational model for controling the gaze direction of a pedagogical agent. We are using a methodogical approach based on digital video corpora. A video corpus was collected. A subset of this corpus was annotated. Rules allowing for controling gaze direction of an agent were then obtained through statistical analysis on the annotations.
Process models have been described by researchers starting in the mid 1990. Current state of the art in technology enhanced learning (TEL) systems development in combination with observations based on using of standards, existing process models, and on supervising team work in a series of diverse TEL systems, have led to the insight, that an extended approach is required. With a strong background...
Technology innovations by default are designed to be generic - discussion boards, LMS, learning objects, Semantic Web technology, OWL, and SCORM. However, educational artifacts that are created employing these technologies, in most cases, could only be utilized locally within classrooms, within courses, and within institutions. This is so because while employing these generic technologies educators...
Although the approaches about how to manifest the technology innovation could contribute to the development of innovative learning technologies, the neglect of teacherspsila individual differences in technology applications may interrupt the technology diffusion. In this paper two case studies about teaching with innovative learning technologies (including mobile learning environment and interactive...
This paper presents an educational networking architecture for integrating long-term learning processes. Learning products generated with a variety of tools can be shared and re-used across a workflow of computer supported activities. The architecture provides interoperability with heterogeneous learning tools and a configurable structure able to adapt to different learning scenarios. The architecture...
Collaborative learning models are widely used in educational institutions. These models require a high interaction level among students and are mainly oriented towards in-class scenarios. But when collaborative models are deployed in a distant scenario, user expressiveness is significantly reduced thus creating a gap that hinders the effectiveness of this collaboration. A computer-supported model...
New statistical methods allow discovery of causal models from observational data in some circumstances. These models permit both probabilistic and causal inference for models of reasonable size. Many domains can benefit from such methods. Educational research does not easily lend itself to experimental investigation. Research in laboratories is artificial while research in authentic environments is...
The standardization of elearning environments and the design of collaboration scripts are two research areas that are acquiring a greater attention within the computer supported collaborative learning (CSCL) community. We are interested in the suitability of the standard IMS-LD for modeling collaborative learning processes. We propose a reference model and the use of a graphical notation called CIAN...
Searching for knowledge is an essential problem that learners face while learning. In a ubiquitous learning environment, it is difficult for a learner to find the right knowledge in time even if the source of this knowledge is very near to his physical location. Therefore, this paper presents a personalized collaborative ubiquitous learning environment in order to support the learner while doing a...
Nowadays many LMSs are available providing a broad range of functionalities and services to support teaching and learning. These systems are appropriate for most common pedagogical approaches, but they are not suitable enough for collaborative and practice-based scenarios. EMLs were proposed several years ago in order to provide a general solution to this problem. Particularly, the well-known IMS...
This paper presents a personalized delivery system aimed at directing the learner to the next resources that need to be accessed in order to obtain best proficiency. The analysis is performed at chapter level. A concept map is has been created for a chapter and than concepts were classified using Naive Bayes classifier. The system recommends concepts that need further study which mean either resource...
In this paper, a project-based collaborative learning (PBCL) meta-model is proposed. It allows a teacher to build up a PBCL scenario and to implement it in a learning system which is not designed to this learning method. A MDA (model driven architecture) approach is described to elaborate transformation rules between the PBCL metamodel and that of the learning system. Moodle platform, used in the...
A negotiation-based intelligent tutoring system of which the tutor and learner agents in playing problem-specific roles is developed to assist learner in problem solving through a negotiation mechanism. During the problem solving, fuzzy constraint-directed negotiation is employed to coordinate the mutual thinking between tutor and learner agents, and it can resolve the cognition differences and thereby...
The integration of interaction and simulation in e- learning systems represents a milestone in educational research and supports the student's learning process in innumerable ways. Nevertheless, current standards do not provide appropriate mechanisms to obtain a significant assessment about the student's performance while interacting with a simulation neither to influence on the teaching-learning...
This paper describes the diagnostic method developed in a learning environment for object-oriented modeling called Diagram. This method compares the studentpsilas diagram with an expertpsilas diagram in order to find the differences between these two diagrams. The principles of our algorithm rely on graph matching methods and algorithms. The diagrams are schematized in characteristic structural patterns...
In this paper we present LEARN-SQL, a system conforming to the IMS QTI specification that allows on-line learning and assessment of students on SQL skills in an automatic, interactive, informative, scalable and extensible manner.
The development of a learning system based on integrating a number of learning services needs both a technological platform to support the system as well as a methodology that manages the development process. Such technological platform is provided by the service oriented learning architecture (SOLA) that defines an architecture style guiding several aspects of deploying units of learning that are...
This paper describes Diagram, a learning environment for UML object-oriented modeling. Diagram supports the learnerpsilas metacognitive activity through two components: a specific interaction framework and a contextual help system. The interaction framework relies on a three steps organization of the task and original graphical modeling tools. Contextual helps facilitate the control and the correction...
In this paper we present an approach, based on exploiting and modeling empirical knowledge, for design an adaptive intelligent tutoring system in medical education. We present our learning knowledge design constraints and their related computer representations. We conclude with the possibilities of our approach and their perspectives.
