The graphics themselves also reflect the evolving nature of different medium

Going around in circles!: around and about a geometric figure
Geometry can be an exercise arena for strengthening those logic muscles that middle school students need to flex. When we work with a geometric figure—a circle, for instance—and apply the ancient tools of compass and straightedge, geometry can become a rich ground for developing design. And a circle has size, so a unit on this topic necessarily brings in the mathematics of its measurement. Circles, then, is a geometric topic that can provide mental challenge, opportunity for artistic develop

Introduction to Stoichiometry
Our on-line Chemistry course covers stoichiometry and demonstrates our scenario based approach to teaching chemistry. Traditional courses tend to follow a bottom-up approach to learning chemistry. This traditional approach teaches abstract concepts and tools before discussing their practical application, which results in students learning bits of unconnected knowledge that are rarely usable let alone memorable. In our approach, scenarios are used both to motivate the material and provide a frame

De l'usager construit à l'usager participant
Ce texte part du constat de la faible diffusion des artefacts produits par la recherche en EIAH. Cette situation résulte, nous semble-t-il, d'une forte discontinuité entre les moments de conception et d'usage pouvant entraîner une discordance entre usages imaginés (prédictifs) et usages « réels ». La conception participative, parce qu'elle repense la place de l'usager, nous paraît être à la fois une réponse possible à cette problématique et un champ de recherche pour l'ingénierie
