Learning styles refer to how a person acquires and processes information. Identifying the learning styles of students is important because it allows more personnalized teaching. The most popular method for learning style recognition is through the use of a questionnaire. Although such an approach can correctly identify the learning style of a student, it suffers from three important limitations...

RÉSUMÉ. La programmation de systèmes réactifs tels que les simulateurs de systèmes dynamiques ou les jeux vidéo est une tâche difficile. Les techniques classiques pour programmer ces systèmes sont fondées sur l’utilisation de bibliothèques de threads ou de programmation événementielle. Nous introduisons ici le langage REACTIVEML comme une alternative à ces pratiques. Le langage est une extensio...

1. Introduction. In this paper we are interested in travelling wave solutions u = u(x; t) of the

Research objects and research outcomes are proposed to act as a guide to select a proper research method. We, however, recommend that the research question as the essential factor of the research process should guide selection. Based on this idea we here develop taxonomy of research approaches with six categories. Taxonomy is then compared with three other classifications of research methods by...

Nous présentons une réalisation purement fonctionnelle et paresseuse de la technique du mode inverse de différentiation algorithmique. Cette technique, qui permet de calculer de manière précise et efficace les dérivées des expressions numériques dans un programme, est devenue indispensable dans plusieurs branches de programmation scientifique. Le mode inverse ou adjoint demande souvent l’usage ...

Data warehouses collect and maintain large amounts of data from several distributed and heterogeneous data sources. Because of security reasons, operational requirements, and technical feasibility it is often impossible for data warehouses to access the data sources directly. Instead data warehouses have to replicate legacy information as detail data in order to be able to maintain their summar...

Developments in computer-mediated communications are not only providing new opportunities for educators but also changing roles and competencies in learning and teaching environments. Experts agree that teaching online requires different roles and competencies. The literature includes several studies on roles and competencies for online teaching. However, as Le Boterf underlines, roles and comp...
