Comment développer l'utilisation de grilles critériées (rubrics) dans les apprentissages ?

National audienceContrairement aux évaluations sommatives qui mesurent la performance de l'apprenant, les évaluations critériées sont centrées sur le processus d'apprentissage et son amélioration. La conception de telles grilles critériées reste néanmoins complexe. Nous proposons dans cet article un début de taxonomie de grilles critériées visant à aider les enseignants dans l'appropriation de ces outils

Gestion de groupes multilingues dans un enseignement scientifique

National audienceDans cet article, nous décrivons une stratégie pédagogique qui permet une intégration harmonieuse entre étudiants francophones et non francophones au sein d'un même enseignement scientifique donné en français. Cette démarche a été testée à Telecom Bretagne, où nous accueillons chaque année une forte proportion (>30%) d'étudiants non francophones (niveaux A2 ou B1 selon le référentiel d'évaluation européen des langues - European Language Evaluation Framework)

Conception fonctionnelle de services d'entreprise fondée sur l'alignement entre coeur de métier et Système d'Information

National audienceThe enterprise organization must fulfil its strategy. Processes describing enterprise business core and enterprise organizational structure enable enterprise to meet this objective. This paper concerns business process driven design of customer oriented services. The description of business processes from customer instead of the production department allows indeed service set providing to the customer by the enterprise. In order to satisfy enterprise objectives, the service design procedure is so based on the Enterprise Architecture (EA) system point of view, whether services are computerized or not. Our service design procedure benefits from EA according to the enterprise strategy realization gap between the target Information System and the business core. This service design procedure adds an enterprise service automated design thanks to model driven engineering to the alignment so defined

Spatial joins are join operations that involve spatial data types and operators. Spatial access methods are often used to speed up the computation of spatial joins. This paper addresses the issue of benchmarking spatial join operations. For this purpose, we first present a WWW-based benchmark generator to produce sets of rectangles. Using a Web browser, experimenters can specify the number of rectangles in a sample, as well as the statistical distributions of their sizes, shapes, and locations. Second, using the generator and a well-defined set of statistical models we define several tests to compare the performance of three spatial join algorithms: nested loop, scan-and-index, and synchronized tree traversal. We also added a real-life data set from the Sequoia 2000 storage benchmark. Our results show that the relative performance of the different techniques mainly depends on two parameters: sample size, and selectivity of the join predicate. All of the statistical models and algorithms are available on the Web, which allows for easy verification and modification of our experiments.Peer Reviewe

FIREBall-2: advancing TRL while doing proof-of-concept astrophysics on a suborbital platform

Here we discuss advances in UV technology over the last decade, with an emphasis on photon counting, low noise, high efficiency detectors in sub-orbital programs. We focus on the use of innovative UV detectors in a NASA astrophysics balloon telescope, FIREBall-2, which successfully flew in the Fall of 2018. The FIREBall-2 telescope is designed to make observations of distant galaxies to understand more about how they evolve by looking for diffuse hydrogen in the galactic halo. The payload utilizes a 1.0-meter class telescope with an ultraviolet multi-object spectrograph and is a joint collaboration between Caltech, JPL, LAM, CNES, Columbia, the University of Arizona, and NASA. The improved detector technology that was tested on FIREBall-2 can be applied to any UV mission. We discuss the results of the flight and detector performance. We will also discuss the utility of sub-orbital platforms (both balloon payloads and rockets) for testing new technologies and proof-of-concept scientific ideasComment: Submitted to the Proceedings of SPIE, Defense + Commercial Sensing (SI19

FIREBall-2: The Faint Intergalactic Medium Redshifted Emission Balloon Telescope

The Faint Intergalactic Medium Redshifted Emission Balloon (FIREBall) is a mission designed to observe faint emission from the circumgalactic medium of moderate redshift (z~0.7) galaxies for the first time. FIREBall observes a component of galaxies that plays a key role in how galaxies form and evolve, likely contains a significant amount of baryons, and has only recently been observed at higher redshifts in the visible. Here we report on the 2018 flight of the FIREBall-2 Balloon telescope, which occurred on September 22nd, 2018 from Fort Sumner, New Mexico. The flight was the culmination of a complete redesign of the spectrograph from the original FIREBall fiber-fed IFU to a wide-field multi-object spectrograph. The flight was terminated early due to a hole in the balloon, and our original science objectives were not achieved. The overall sensitivity of the instrument and telescope was 90,000 LU, due primarily to increased noise from stray light. We discuss the design of the FIREBall-2 spectrograph, modifications from the original FIREBall payload, and provide an overview of the performance of all systems. We were able to successfully flight test a new pointing control system, a UV-optimized, delta-doped and coated EMCCD, and an aspheric grating. The FIREBall-2 team is rebuilding the payload for another flight attempt in the Fall of 2021, delayed from 2020 due to COVID-19.Comment: 23 Pages, 14 Figures, Accepted for Publication in Ap

Expressiveness and Complexity of Active Databases

. The expressiveness and complexity of several active database prototypes are formally studied. First, a generic framework for the specification of active databases is developed. This factors out the common aspects of the prototypes considered, and allows studying various active database features independently of any specific prototype. Furthermore, each of the prototypes can be specified by specializing certain parameters of the framework. The prototypes considered are ARDL, HiPAC, Postgres, Starburst, and Sybase. Using their formal specifications, the prototypes are compared to each other with respect to expressive power. The results provide insight into the programming paradigm of active databases, the interplay of various features, and their impact on expressiveness and complexity. 1 Introduction The ability of a database to react to specified events is an increasingly common requirement in advanced database systems. This has led to the emergence of active databases, which provide..
