Nouveaux enjeux pour l'école moyenne en Afrique
2005
05113; On constate aujourd'hui une augmentation massive de la scolarité des 12-16 ans dans les pays africains en développement. Ce phénomène est lié au développement voulu et obtenu des scolarités primaires.Pour diverses raisons, l'école moyenneconstitue un cycle terminal pour la grande majorité des enfants qui la fréquentent. Son organisation actuelle, telle qu'on peut l'observer dans différents pays, est cependant très proche du collège secondaire français et donc inapte à fournir le cadre adéquat pour un cycle terminal générateur de progrès économiques et sociaux.Bâti sur cette problématique de l'articulation entre les flux d'élèves, les contenus pédagogiques et les modalités d'organisat…
Synthesis and magnetic properties of an iron 1,2-bisthienyl perfluorocyclopentene photochromic coordination compound
2011
Abstract The coordination compound Fe(BM-4-PTP) 2 (NCS) 2 ⋅2MeOH ( 1 ) including the photoisomerizable ligand BM-4-PTP (1,2-bis(2′-methyl-5′-(pyrid-4″-yl)thien-3′-yl)perfluorocyclopentene) was obtained as an orange powder. The powder turns blue upon photocyclization of the 1,2-bisthienyl photochromic ligand induced by UV light irradiation at room temperature. Photocycloreversion is obtained by visible light irradiation of the material in the solid state. The orange and blue powders were investigated over the temperature range (5–293 K) and pressure range (1 bar–12 kbar) by magnetic susceptibility measurements and variable temperature 57 Fe Mossbauer spectroscopy. The photo-induced colour ch…
La relation entre réformes des programmes scolaires et acquisitions à l'école primaire en Afrique : réalité ou fantasme ? L'exemple de l'approche par…

This paper proposes a critical analysis of the introduction and implementation of new school curricula in Africa based on the example of the skills based approach (SBA). In many countries, the SBA has been chosen as the most appropriate and relevant method to change their school curriculum and improve education quality. We analyse the implementation of those new curricula based on the SBA in primary schools in Mauritania. The results show that the main problems about pupil's achievement lie rather in the effective implementation of curricula in the classrooms than in their contents. Additional analyses show that this result is confirmed, as well, in other African countries. As a background …
: Evolution of the examination at the end of college in sub-Saharan Africa
2004
The evolution of schooling in the developing systems in sub-Saharan Africa has brought a sizeable new population into the colleges. Unfortunately, the scarcity of resources and the need to pursue development of basic education prevents maintaining this population in the lycees. Thus the examination at the end of college becomes the focus of very stressful management of different currents and finds itself divided about aims which are not easy to reconcile. Original solutions can be found, as is the case in Mauretania, while the combination of better-known solutions may allow this examination to deal with these contradictions.
