Writing to Learn Mathematics: A Mixed Method Study
This study sought to address a research gap by studying students who had been taught mathematics using writing. The purpose of this study was to provide an analysis of students’ perceptions of the benefits and drawbacks of this pedagogical approach. The types of writing students performed in mathematics classes were described, and students’ preferences regarding these tasks were analyzed. Finally, a comparison was made between female and male students’ responses in order to see whether gen

Why Web 2.0 is Good for Learning and for Research: Principles and Prototypes
The term "Web 2.0" is used to describe applications that distinguish themselves from previous generations of software by a number of principles. Existing work shows that Web 2.0 applications can be successfully exploited for technology-enhance learning. However, in-depth analyses of the relationship between Web 2.0 technology on the one hand and teaching and learning on the other hand are still rare. In this article, we will analyze the technological principles of the Web 2.0 and describe thei

Modélisation de profils d'élèves à partir de traces de résolution de problèmes
La modélisation automatique des connaissances de l’apprenant est nécessaire dès lors que l’on cherche à accompagner un apprentissage dans le cadre des EIAH. Dans ce rapport, nous présentons un travail en cours dans lequel des techniques de classification automatique permettent d’engendrer des modèles d’élèves interprétables par un enseignant ou un didacticien et utilisables éventuellement par un « tuteur » automatique. L’approche proposée a été appliquée au domaine de la ré

A Bayesian Student Model without Hidden Nodes and Its Comparison with Item Response Theory
The Bayesian framework offers a number of techniques for inferring an individual's knowledge state from evidence of mastery of concepts or skills. A typical application where such a technique can be useful is Computer Adaptive Testing (CAT). A Bayesian modeling scheme, POKS, is proposed and compared to the traditional Item Response Theory (IRT), which has been the prevalent CAT approach for the last three decades. POKS is based on the theory of knowledge spaces and constructs item-to-item gra

Motivating learning in mobile and game-based environments - Experiences in everyday classroom work -
The world around us has changed. The pedagogy of the classroom has stayed more or less the same for decades, offering a stark contrast to the rate of change in other fields. Inspiration for change can be found in the veritable passion for new technologies, such as mobile devices and game technology, displayed by younger generations. The real challenge is to import these technological advancements into the classroom and, furthermore, educating teachers about the possibilities they hold. We have r

Purpose and design of an ePortfolio
The focus of this contribution is the relationship between the purpose to use an ePortfolio and its design. By highlighting the relationship between purposes and design of an ePortfolio, we want to present a framework that gives directives to use an ePortfolio in an educational context. When used for lifelong learning and / or ‘assessment for learning’, student-ownership and reflection are important characteristics. When used for accreditation (=’assessment of learning’) the use of ‘standar

To set up pedagogical experiments in a virtual lab: methodology and first results
This paper concerns a methodology for setting up web based experiments by distinguishing two perspectives: the learning perspective (which tasks will be scheduled for pupils and tutors, how they are planned and what learning objectives they may attempt), and separately, the experiment perspective (how teachers or researchers may use trails of this experiment, the first to improve their teaching, the last to various research objectives). The both are described by computable “scenarios” expresse
