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

L’utilisation d’un arbre des tâches pour concevoir et analyser des situations d’apprentissage :
Afin de prendre en compte les difficultés que les élèves ont pour donner du sens aux activités expérimentales, ce qui leur fait perdre de vue l’objectif initial du T.P. et les connaissances visées, nous proposons de leur faire concevoir le protocole des expériences.
