Analysis of three different models used to acquire three e-learning solutions at the same university
The Universtiy of Pretoria has been using an electronic assessment system since 1991 and a learning management system (LMS) since 1998. Both systems required urgent upgrading. In 2003 a further need arose in the Faculty of Health Sciences, for an electronic portfolio system. The Department for Education Innovation has thus implemented three new systems during the past three years: a new electronic assessment system, an upgraded LMS, and an electronic portfolio system. This paper analyzes the adv

Sign Language Interpreters’ Training
Nowadays, the evolution of technology and the increasing use of computers gave the opportunity for developing new methods of education of deaf individuals and sign language interpreters. The e-learning environments that have been developed for the education of sign language provide web-based courses, designed to effectively teach to anyone the Sign Language. Recognizing the difficulties and barriers of sign language training as well as the importance of sign language interpreters for the communi

A User-Friendly Sign Language Chat
The introduced concept of a gesture based sign language chat enables the communication of hearing impaired people over networks, including concerns regarding low throughput and bandwidth characteristics. Existing applications handle that task not appropriate, since either high bandwidth networks are necessary or the extensibility of the vocabulary is complicated for untrained users. Thereby our approach facilitates existing image recognition techniques for the determination of gestures which are

An adaptive learning environment in DICE system with TDD model
We introduce an adaptive learning environment named DALM (DICE adaptive learning model) based on DICE test-driven development (TDD) model that was implemented in a parse-tree based automatic on-line grader. In our opinion, there are three variables in DALM. The individual differences (I) classify the learners into several groups. The training method (T) that equivalent to TDD model in DICE can be controlled by DICE system. The learning outcome (O) presents the learning performance of learners wi

Model-based Design of Activity Spaces for Collaborative Problem Solving and Learning
It is investigated how the design of external representations, namely, concept maps, can be based on a simulation model, how model-based concept maps can be utilized in an instructional and collaborative problem solving setting and how they can be taken advantage of in a computerized environment for collaborative problem solving and learning. With respect to the first goal, we made use of a cognitive simulation model to develop two instructional units. One unit teaches qualitative aspects of cla

Intelligent Tutoring Goes To School in the Big City
This paper reports on a large-scale experiment introducing and evaluating intelligent tutoring in an urban High School setting. Critical to the success of this project has been a client-centered design approach that has matched our client's expertise in curricular objectives and classroom teaching with our expertise in artificial intelligence and cognitive psychology. The Pittsburgh Urban Mathematics Project (PUMP) has produced an algebra curriculum that is centrally focused on mathematical anal

Task and Interaction Regulation in Controlling a Traffic Simulation
In collaborative problem solving, metacognition not only covers strategic reasoning related to the task but also reasoning related to the interaction itself. The hypothesis underlying this work states that regulation of the interaction and regulation of the task are closely related mechanisms and that their co-occurrence facilitates collaborative problem solving. These assumptions are tested experimentally with a traffic simulator. The results show that co-occurrence of task and interaction regu

Elaborating new arguments through a CSCL scenario
The CSCL community faces two main challenges with respect to learning and argumentation. The scientific challenge is to understand how argumentation produces learning, that is to discover which cognitive mechanisms, triggered by argumentative interactions, generate new knowledge and in which conditions. The engineering challenge is to determine how to trigger productive argumentation among students. These two challenges are often investigated in parallel, but this contribution focuses on the lat

An approach to distance learning curriculum appropriation
The work presented aims at supporting distance learning students in their appropriation of a curriculum. We propose an approach that consists in helping students to construct individual projects. We dissociate different aspects (planning, evaluation and regulation) that can be useful for this purpose, propose a technological approach (epiphyte system, ontology-based model) and example of tools currently provided by the Saafir framework.

Cowos: A Model of Collective Work Situations to Support Modelling and Simulation Based Approaches of
This paper describes an operational model of collective work situations. This model is rooted in the CHAT theory. It allows creating multi-agent simulations where the agents’ behaviour is defined in terms that make salient organization issues, and allows building learning situations that focus on making students consider explicitly these issues.

Enhancing the Adaptivity of an Existing Website with an Epiphyte Recommender System
In this paper we propose an approach to enhance the adaptivity of an existing Website by plugging on top of it (“epiphyte approach”) a recommender system that displays additional tips and functionalities in a separate window. The recommender system analyzes the way the user browses through the Website according to predefined prototypical ways of using the Website (“models of use”) and then proposes information or functionalities that appear useful according to this model of use.

Understanding weblog communities through digital traces: a framework, a tool and an example
Often research on online communities could be compared to archaeology [16]: researchers look at patterns in digital traces that members leave to characterise the community they belong to. Relatively easy access to these traces and a growing number of methods and tools to collect and analyse them make such analysis increasingly attractive. However, a researcher is faced with the difficult task of choosing which digital artefacts and which relations between them should be taken into account, and h

Regulative support during inquiry learning with simulations and modeling
Many factors impact learning; the environment and resources available, the domain, how much prior-knowledge a student has, and how well they make use of their metacognitive skills, all of these factors impact new knowledge creation. The series of studies described in this dissertation focuses on the latter; i.e. the metacognitive skillfulness of students. Known collectively as self-regulation, planning, monitoring, and evaluation, when applied appropriately will enhance learning. Students who m

Designing biases that augment socio-cognitive interactions
This chapter questions the assumption that the best environment for computer-supported collaborative learning is the one that most closely reproduces the features of face-to-face collaboration. Empirical studies have failed to establish the superiority of group interaction with richer media. Instead, the chapter explores media features that do not exist in face-to-face interactions and explains how these features might augment group cognition. The first feature, the persistency of the informatio
