Chapter
In this work, we propose a learning analytics implementation based on a model-driven engineering approach. It aims at assessing the benefits that could arise from such an implementation, when pedagogical resources are produced via publishing chains, that already use the same approach to produce documents. Previously, we have discussed these potenti...

Résumé : Parmi toutes les décisions que doit prendre un enseignant dans sa pratique professionnelle, nous appelons décisions didactiques celles qui visent à permettre aux élèves l’étude d’un savoir à enseigner. Quel modèle pour comprendre ces décisions ? Nous présentons un modèle articulant deux cadres théoriques, la théorie des situations didactiq...
Chapter
Procrastination is a widespread self-regulatory failure. It consists in voluntarily delaying work despite expecting to be worse-off the day after. Procrastination impacts students’ performance and well-being. Therefore it is argued that universities could and should play a more active role in helping freshmen improve their time management. We desig...

Introduction: In 2006, the Grenoble-Alpes University Medical School decided to switch the learning paradigm of the first year to a blended learning model based on a flipped classroom with a continuous dual assessment system providing personal follow-up. We report a descriptive analysis of two pedagogical models. Methods: The innovative blended l...
Conference Paper
Our objective is the design of a Virtual Learning Environment to train a person performing a work activity, to acquire non-technical skills during the experience of a critical situation. While the person’s performance level is due to carefully acquired technical skills, how it is maintained in front of criticality depends on non-technical skills, s...
Conference Paper
Adaptation in learning environments can be performed according to various aspects, such as didactics, pedagogy or game mechanics. While most current approaches propose to adapt according to a single aspect, this paper proposes a Multi-Aspect Generic Adaptation Model (MAGAM). Based on the Q-matrix, this model aims at taking into account heterogeneou...

Multi-players learning games (MPLG) tend to foster learners’ engagement and immersion in learning games’ activities. They are an interesting way to organize learning situations in which learners interact with each other and solve challenges. In this context, teachers need to orchestrate MPLGs’ scenarios to arouse desired interactions such as cooper...
Conference Paper
In most technical domains, non-technical skills have an influence on a worker’s performance. Studies have shown that these skills are most influential during critical situations, where usual technical procedures cannot be successfully applied. This article describes the challenges raised by the diagnosis of non-technical skills during critical situ...
Conference Paper
Knowledge acquisition is a crucial problem for the design of Intelligent Tutoring Systems (ITSs). To overcome this problem, authoring tools have been proposed. Over two dozen of authoring tools have been built since the earliest days of ITS, but each of them focuses on a particular kind of ITSs such as constraint-based tutors or model-tracing tutor...

Chapter
European universities are facing a massification of education, which leads to classes with the size of more than 1000 students in massive online courses (or in short “MOCs”, including the open version of MOOCs as a subcategory). This Grand Challenge Problem deals with the application of adaptive and adaptable educational technologies that exploit u...
Chapter
Currently, many Learning Analytics (LA) initiatives are carried out throughout Europe. Typically, LA have been developed and are provided for one specific stakeholder group such as students or teachers of a university. In some cases the exploitation of technology usage data lacks the consideration of ethical issues, for instance if students are not...

We propose a method and a first authoring tool to assist the design and implementation of diagnostic techniques. This method is independent from the domain and allows building more than one technique at once. The method is based on knowledge representation and a semi-automatic machine learning algorithm. We tested the method in two domains, surgery...
Conference Paper
We describe a method to evaluate how student models affect ITS decision quality – their raison d’être. Given logs of randomized tutorial decisions and ensuing student performance, we train a classifier to predict tutor decision outcomes (success or failure) based on situation features, such as student and task. We define a decision policy that sele...
