app.efrançais.lu is a new web application commissioned by the Luxembourgian Service de Coordination de la Recherche et de l'Innovation pédagogiques et technologiques (SCRIPT) that allows students to learn the French language in an interesting and playful manner in the framework of their eFrançais initiative.
app.efrançais.lu is a web application built to help young Luxembourgish-speaking pupils to learn French. Pupils have two kinds of exercises at their disposal: one of them is about guessing images associated to sounds, and the other one is about guessing sounds associated to an image. The user interface is designed to ensure a most intuitive and interruption-free experience.
Nice visual animations make the user experience more interactive. The application was designed mobile-first with tablets in mind, but as a Progressive Web Application (PWA) it is 100% responsive, working just as well on phones as on desktop browsers.
Users are able to persist their progress through the various levels by signing in to their SSO iam.education.lu account. Technically, this was solved by acting as a service provider in a Security Assertion Markup Language (SAML) context.
User-data, user-progress and resources are stored in a MongoDB NoSQL database. We've chosen this database technology because it proved to be a great fit for our simple data model with its promises of shorter development cycles compared to standard RDBMS databases. The final result consists in an intuitive application, that all users will be able to use instinctively
