AstroGrid as an e-Learning Environment
We present the concept of the Virtual Observatory through the AstroGrid project, which is a Virtual Organization making intensive use of the Internet to produce a working data-grid for Astronomical applications. AstroGrid has implemented a series of tools which facilitate collaborative work such as news, forum and discussion pages, all of them inspired by the open source and licensing philosophy. Additionally we explore how such an Astronomical Grid project can be used in the future as an e-Le

Un modèle d’élève par l’analyse statistique implicative. Prise en compte du contexte algébri
Le modèle d’élève que nous construisons cherche à donner une représentation fine des compétences cognitives des élèves dans le domaine de l’algèbre. Il se fonde sur les micro-actions enregistrées dans le micromonde Aplusix. Ces actions étant de niveau très fin, nous devons reconstruire les connaissances à un niveau plus abstrait : non pas une action isolée mais un ensemble d’actions « similaires » apparaissant dans un même contexte. Nous utilisons pour cela l’analyse sta

Structuring and merging Distributed Content
A flexible approach for structuring and merging distributed learning object is presented. At the basis of this approach there is a formal representation of a learning object, called attribute structure. Attribute structures are labeled directed graphs representing structured information on the learning objects. When two or more learning objects are merged, the corresponding attribute structures are unified, and the unified structure is attached to the resulting learning object.

Derivation of Knowledge Structures for Distributed Learning Objects
Knowledge space theory (Doignon & Falmagne, 1985; Albert & Lukas, 1999; Doignon & Falmagne, 1999) offers a rigorous and efficient formal framework for the construction, validation, and application of e-assessment and e-learning adaptive systems. This theory is at the basis of some existing e-learning and e-assessment adaptive systems in the U.S. and in Europe. Such systems are based on a fixed and local domain of knowledge, where fixed means that the domain does not change in time and local ref

Floodplain Modeling
Students explore the impact of changing river volumes and different floodplain terrain in experimental trials with table top-sized riverbed models. The models are made using modeling clay in an aluminum baking pans placed on a slight incline. Water added "upstream" at different flow rates and to different riverbed configurations simulates different potential flood conditions. Students study flood dynamics as they modify the riverbed with blockages or levees to simulate real-world scenarios.

Building-Stone Geology
This laboratory activity gives an example of the creativity required when teaching non-native rock types. In order to study igneous and metamorphic rocks in central Florida (a huge area consisting solely of sedimentary rock), geology students examined building stones in downtown St. Petersburg. Each student picked a particular rock type used in a particular way (structure, decorative facade, etc.), performed geologic tests on it, read up on its properties, history, and uses, and prepared a paper
