Technology and mathematics in the classroom: lights and shadows
نویسنده
چکیده
RESUME: Les recherches conduites sur les Technologies pour l’Information et la Communication (TIC) ont pour but surtout de décrire les aspects techniques de l’innovation permise par leur usage. Ici on introduit deux critéres qui considérent l’usage des TIC dans une perspective cognitive et culturelle. Le premier critère considère les TIC comme des systèmes culturelles sémiotiques. Le deuxième, comme des énergisseurs cognitifs intrinsèques.. On peut ainsi analyser les TIC d’un point de vue culturel et cognitif et les considérer, dans certains cas, comme des infrastructures représentationnelles, c’est-a-dire, comme des structures socio-culturelles qui peuvent re-définir notres connaissances, en particulier celles de l’école. Dans l’analyse, on souligne le rôle fondamental de l’enseignant comme médiateur, outre que comme auteur du projet didactique qui organise un milieu convenable pour l’apprentissage, où les ingrédients cités trouvent leur place. Un espace de action, communication et production est créé, où l’apprentissage des mathématiques peut avoir lieu. Dans la présentation orale on donnera une description de cet espace dans le cas specifique des TICS: on fera référence à une expérience conduite au niveau du lycèe à propos du concept de fonction et à une approche précoce à quelques concepts de l’analyse mathématique.

Removing car shadows in video images using entropy and Euclidean distance features
Detecting car motion in video frames is one of the key subjects in computer vision society. In recent years, different approaches have been proposed to address this issue. One of the main challenges of developed image processing systems for car detection is their shadows. Car shadows change the appearance of them in a way that they might seem stitched to other neighboring cars. This study aims ...

متن کاملHigh Quality Shadows for Real-Time Crowds
Real-time shadowed crowds, especially under locally lit environments, pose several distinct challenges. Current solutions for crowds are either very simplistic for multiple lights or only handle a single directional light with shadows. This work focuses on bringing hundreds of local lights with high fidelity shadows for crowds into the real-time domain. Each light is given the ability to cast s...
متن کاملEnhancing Mathematical Understanding through an Optimization Problem of Delay at Fixed-Cycle Traffic Lights
Delay at traffic lights is a real life problem that each of us has ever encountered. Therefore it is an ideal example for the promotion of the applicability and usefulness of mathematics. As delay is to be avoided, an optimization problem arises as a function of the time period of green lights. The function to be minimized is also another interesting discussion item. Queues at fixed-cycle traff...
