Efficacité pédagogique des classes à cours double à l'école primaire: le cas du cours préparatoire

2010

National audience; Sur la base d'analyses nouvelles, cet article se centre sur l'efficacité pédagogique des classes à plusieurs cours à l'école élémentaire, et plus particulièrement sur la classe de CP (cours préparatoire). Les résultats principaux indiquent que c'est la configuration CP-CE1 qui constitue le contexte le plus défavorable aux apprentissages des élèves. Cette inefficacité relative des cours doubles peut toutefois être compensée par l'expérience professionnelle de l'enseignant. L'article propose également une synthèse sur l'efficacité des classes à cours multiple à l'école élémentaire, au regard des travaux récents, et ouvre des pistes de réflexion sur cette question de politiq…

Efficacité pédagogique des classes à plusieurs cours: des résultats nouveaux qui relancent le débat

2006

Les notes de l'IREDU, n°06/01, septembre 2006; Cette synthèse propose une analyse de l'efficacité pédagogique des classes à plusieurs cours à l'école élémentaire. Les résultats de cette recherche indiquent que la fréquentation d'un cours double, en CE1 comme en CM1, n'est jamais positive sur les acquisitions des élèves et qu'elle est au mieux neutre quand les élèves peuvent faire l'objet d'une affectation délibérée de la part des enseignants. Si ces résultats malmènent sérieusement les conclusions des travaux antérieurs français, on note que le contexte a changé puisque d'une part, les classes à plusieurs cours ne sont plus à présent une spécificité rurale et, d'autre part, elles se limiten…

A multiple-response chi-square framework for the analysis of Free-Comment and Check-All-That-Apply data

2021

International audience; Free-Comment (FC) and Check-All-That-Apply (CATA) provide a contingency table containing citation counts of descriptors by products. The analyses performed on this table are most often related to the chi-square statistic. However, such practices are not well suited because they consider experimental units as being the citations (one descriptor for one product by one subject) while the evaluations (vector of citations for one product by one subject) should be considered instead. This results in incorrect expected frequencies under the null hypothesis of independence between products and descriptors and thus in an incorrect chi-square statistic. Thus, analyses related …

On improving the accuracy of Visible Light Positioning system using deep autoencoder

2020

International audience; DC-biased optical Orthogonal Frequency DivisionMultiplexing (DCO-OFDM)-based visible light positioning (VLP)technology along with the Received Signal Strength(RSS) po-sitioning algorithm is widely used to achieve centimeter levelpositioning accuracy for incoming 5G era, especially indoorenvironment. However, the DCO-OFDM has the peak-to-averagepower ratio (PAPR) issue which imposes the nonlinear distortionand it will directly affect the positioning accuracy in the VLPsystem. The PAPR reduction scheme is urgently needed. There-fore, in this paper, the impact of PAPR reduction scheme onpositioning accuracy is investigated. The positioning accuracywith and without the s…

Climate and agriculture: empirical evidence for countries and agroecological zones of the Sahel

2022

International audience; ow heterogenous is the impact of climate change across space and the type of agricultural production? In this paper, we investigate the relationship between climate change and variability, measured by temperature and rainfall, and agricultural production at the country and agroecological zone levels of the Sahel. We consider a crop production index and five cereals (maize, millet, sorghum, wheat and rice). Based on an original climate database and an agricultural production function estimated for the period 1961–2016, we show that average rainfall and temperature during the growing season indeed have highly heterogeneous effects on agricultural production, depending …

Clinical and MRI measures to identify non-acute MOG-antibody disease in adults

2022

Abstract MRI and clinical features of myelin oligodendrocyte glycoprotein (MOG)-antibody disease may overlap with those of other inflammatory demyelinating conditions posing diagnostic challenges, especially in non-acute phases and when serologic testing for MOG antibodies is unavailable or shows uncertain results. We aimed to identify MRI and clinical markers that differentiate non-acute MOG-antibody disease from aquaporin 4 (AQP4)-antibody neuromyelitis optica spectrum disorder and relapsing remitting multiple sclerosis, guiding in the identification of patients with MOG-antibody disease in clinical practice. In this cross-sectional retrospective study, data from 16 MAGNIMS centres were i…
