Diagnostic models of intelligent tutor system for teaching skills to construct control object freque
In this paper one solution for teaching skills to construct the control object frequency characteristics method is described. Student’s mistakes are discovered and classified. Based on signal-parametric approach to fault diagnosis in dynamic systems mathematical diagnostic models which allow detecting mistake classes by comparing student calculated results and system calculated results are created. Features of proposed diagnostic models application are presented. Intelligent tutor system is dev

Pedagogical evaluation of e-learning courses - Adapted pedagogical index
E-learning is becoming an important part of education and it can provide new possibilities for disabled people. Critical evaluation is becoming indispensable, especially in e-learning systems supporting disabled people, as very little has been done in this area. This paper describes the development of adapted pedagogical index (AdaPI), which demonstrates the pedagogical effectiveness of different courses created and adapted for disabled.

Important Ornaments: The Impact of Graphics and Rule Systems on Academic Wiki Use
Collaborative websites, or wikis, are being used in the classroom to recruit user attention and to disseminate information [1). These wikis place a heavy emphasis on text, while generally neglecting graphics. Little to no research has examined the impact of this textual approach. This paper examines the use of graphics and rule systems as motivating tools in academic wikis. It reports the results of a 6 month long experiment involving 21 10th and 11th grade users to determine the impact of diffe

Analysis and Intelligent Support of Learning Communities in Semi-structured Discussion Environments
Conventional discussion environments provide the technical platform for distributed discussion and collaboration, but apart from some statistical data collected, rarely provide information about the collaborative interactions taking place within the environement or even support the discussion by stimulating the learning setting according to the current situation. In this article we present our approach for intelligent support of groups of learners in distributed web-based discussion environments

Using Interaction Analysis to reveal Self-Regulated Learning in Virtual Communities
Aim of this paper is to analyse whether Interaction Analysis can help investigate the practice and development of Self-Regulated Learning (SRL) in Virtual Learning Communities (VLC). Interaction analysis is increasingly used to study learning dynamics within online activities. It proceeds by searching expressions that reveal the aspects under study in the written messages exchanged by the learners. To this end, we devised and classified a number of indicators suggesting the existence of self-re

Supporting information comparisons in example-based hypertext environments
Global comparisons of learning from hypertext and traditional text have yet failed to show major advantages concerning the effectiveness of hypertext learning. In the current paper it is proposed that an effective hypertext design needs to be based on thorough cognitive task analyses with regard to structures, processes, and resources that are required to benefit from a specific learning approach. This claim is illustrated by two experiments, in which we investigated two methods for supporting e

Dialectics for collective activities: an approach to virtual campus design
This contribution is an attempt to systematise our approach to the design of a virtual campus. Activities in the recently started TECFA virtual campus rely on Internet tools, but they concern both distance teaching and presential interactions. Designing learning activities is relatively easy when the learning goal is an activity in itself. In this contribution, we explain how we extend the “learning by doing” approach to the acquisition of declarative knowledge. After fulfilling a pseudo-task,

Learning from Explanations: Extending One's Own Knowledge During Collaborative Problem Solving by At
On the basis of an experimental study, we propose a cognitive simulation model of collaborative problem solving and learning. In the experimental study, we investigated how qualitative and quantitative problem representations in classical mechanics are acquired and successively interrelated during collaborative problem solving. Two students, who were taught different aspects of classical mechanics, collaborated on problems which were beyond the competence of each of them individually. Students s

Supporting Learners’ Appropriation of a Web-Based Learning Curriculum
This article presents an approach and tools that can help learners appropriate a Web-based learning curriculum and become active participants in their learning. The approach is based on a detailed modeling of the curriculum and intends to equip the learners with different computer-based tools facilitating a multiple point of view perception of the curriculum, while promoting self evaluation and self regulation of the learners’ curriculum performance. The proposed architecture is generic and can

When less is sometimes more: Optimal learning conditions are required for schema acquisition from mu
While it is usually claimed that multiple examples for the illustration of problem categories are a necessary prerequisite for schema acquisition, there is a lack of conclusive empirical evidence supporting this claim. Moreover, there are findings indicating that carefully designed one-example conditions may allow for profitable processes of example comparison as well. In line with this reasoning, we present an experiment – that builds up on a series of studies conducted by Quilici and Mayer (1

The defining characteristics of intelligent tutoring systems research: ITSs care, precisely
his paper argues that, despite the changes in philosophies and techniques that have occurred since ITS research began, there are continuous threads running through this research which define its essential and distinctive nature. In particular, ITSs are computer-based learning systems which attempt to adapt to the needs of learners and are therefore the only such systems which attempt to 'care' about learners in that sense. Also, ITS research is the only part of the general IT and education fie
