Rôle des évaluations continues dans la prédiction des performances des élèves au secondaire collégial

La présente étude traite l’effet de l’évaluation continue (contrôle continu) sur les performances des élèves lors des examens de fin de semestres (examen local, examen régional et note globale d‘évaluation) en Mathématiques et en Sciences physique. Pour ce faire, un échantillon de plus de 2600 élèves de la troisième année du secondaire collégial des établissements scolaires de la direction provinciale d’El Jadida, Académie Régionale d’Education et de Formation de Casablanca-Settat (Maroc) a été choisit. Les données collectées sont analysées à l'aide du coefficient de corrélation de Pearson ainsi que le test t de student. Les résultats obtenus montrent des valeurs élévées des coefficients déterminés et qui sont statistiquement significatifs (p< 0,05). Cela implique que l’évaluation continue influe positivement les performances des élèves en examen local et en note globale d’évaluation pour les deux matières étudiées. Sur la base de ces résultats, il est plus judicieux que l'évaluation continue reçoive une attention plus sérieuse de la part des enseignants. This study examines the effect of continuous assessment on the performance of students in end-of-semester exams (local exam and regional exam), and the global assessment scores in Mathematics and Physical Sciences. To do this, a sample of more than 2,600 pupils of secondary school of the provincial direction of El Jadida, Regional Academy of education and training of Casablanca-Settat (Morocco) was chosen. The data collected is analyzed using the Pearson’s Product Moment Correlation Coefficient (r) as well as the student's t test. The results obtained show high values of the determined coefficients which are statically significant at 0.05. This implies that continuous assessment positively influences student performance in the local exam and the global assessment scores for the two subjects studied. However, this continuous assessment did not have a strong impact on the learning progress of the students in the regional exam. Based on these results, it is more appropriate for the continuous assessment of students to receive more serious attention from the teachers

Adaptation of Bivalve Molluscs to Environmental Conditions in the Coastal Region of El Jadida (Morocco): Case of Mytilus Galloprovincialis

The aim of this study is to assess the impact of industrial pollution on the growth and reproduction of the mussel Mytilus galloprovincialis from coastal region of El Jadida (Morocco). To this aim, three stations (S1, S2 and S3) are chosen according to their proximity to the industrial effluents of the chemical complex. The seawater and mussels (N = 100/ station) samples have been randomly and monthly collected for a period of 6 months (February-July 16). Mussels are distributed in 6 classes of size and measures of condition index and gonadic index are performed in the most common size classes. The results of the analysis of physicochemical parameters of the water show spatio-temporal variations with an acidic pH, high temperature and low salinity in the station near of industrials effluents. Regarding condition index and the gonadic index, there is no significant difference between the mussels collected from the reference station (S2) and the polluted station (S3). This can be explained partly by the adoption of a strategy of adaptation to the environmental stress caused by the industrial pollution

Prevalence of Bovine Tuberculosis Gross Lesions in Doukkala slaughterhouses, Morocco

In Morocco, tuberculosis (TB) is a major zoonotic disease with very serious hygienic and economic impacts. Our study aimed to investigate bovine tuberculosis in two Moroccan slaughterhouses in Doukkala area based on the observation of macroscopic gross lesions. 4198 cattle were examined for tuberculosis lesions during the period of end of May 2014 to July 2015.The results showed that 64.4% of cattle with TB lesions were male with a dominant age of less than or equal to 2 years (67.2%). Females represented only 35.6% with a dominant age between 4 and 8 years (62.3%). The dominant breed was the cross breed of imported and local breeds with 95.4%. Tuberculosis-like lesions were observed in 194 animals (4.6%) including 10 (5.15 %) of generalized and 184 (94.85 %) of localized lesions, mainly encountered in the lungs (44.83%), the head lymph nodes (42.32%) the liver and its associated lymph nodes (9.41%). An estimated overall daily prevalence of 4.6% and a daily average of 5.4% (95% CI: 4.7 - 6.1%) were noted. Compared data obtained from the slaughter database 1.97 % (95% CI: 1.8 – 2.4), this prevalence is more than twice of estimated average (RR=2.34). This assumes that routine inspection leaves more than 50% of animals with suspicious lesions. On the other hand, 390 gross lesions were collected for culturing. An isolation frequency of Mycobacterium of 85.6% was obtained and the LPJ and Herrold seem to be the best culture media

Ataxia in Multiple Sclerosis: From Current Understanding to Therapy

Ataxia is a type of neurological disorder that affects the ability to coordinate voluntary movements, such as walking, balance, and speech. In people with multiple sclerosis (MS), ataxia is a common symptom, affecting around 80% of people with the condition. The cause of ataxia in MS is still unknown; however, it is thought to be due to damage to the part of the central nervous system (CNS) that controls balance, coordination, and movement, especially the cerebellum. Symptoms of ataxia in people with MS can range from mild to severe, and can include a lack of coordination, difficulty speaking, difficulty walking, and gait. Ataxia management in MS typically involves pharmacotherapy to improve coordination, physiotherapy to enhance strength and balance, surgical procedures to alleviate tremor as well as occupational therapy to help with everyday activities

New Alien Mediterranean Biodiversity Records (October 2020)

This article includes 23 new records of alien and cryptogenic species in the Mediterranean Sea, belonging to 4 Phyla (Chordata, Echinodermata, Arthropoda and Mollusca), distributed from the Alboran to the Levantine Sea. Records are reported from eight countries listed from West to East as follows: Algeria: new records of the Atlantic blue crab Callinectes sapidus; Spain: further spread and establishment of the sea slug Lamprohaminoea ovalis in continental shores; Tunisia: first record of the Atlantic Blue Crab Callinectes sapidus in the Gulf of Gabes; Italy: a new occurrence of the pufferfish Lagocephalus sceleratus in Northern Ionian waters; first record of Cephalopholis taeniops in the Ionian Sea; first record of the redlip blenny, Ophioblennius atlanticus in the Ionian Sea; Slovenia: first record of the isopod Paranthura japonica in Slovenia; Greece: first record of the molluscs Eunaticina papilla, Plocamopherus ocellatus and the fish Cheilodipterus novemstriatus; first record of the ascidian Ecteinascidia turbinata in Kriti; the long-spined sea urchin Diadema setosum in the Ionian Sea; Turkey: first record of the sea spider Ammothea hilgendorfi; the stomatopod Cloridina cf. ichneumon; the fishes Pempheris rhomboidea from the Sea of Marmara and Paranthias furcifer from the Aegean Sea; Lebanon: new records of the fishes Arothron hispidus, Rachycentron canadum, Heniochus intermedius and Acanthurus monroviae; first record of Acanthostracion polygonius. The records of Cloridina cf. ichneumon from southern Turkey and the fish Acanthostracion polygonius from Lebanon, both being the first Mediterranean records, are noteworthy

Relationship between percentage of VO2max and type of physical activity in obese and non-obese adolescents

International audienceAIM: The objective of the present study was to determine oxygen uptake (VO(2)) and percentage of maximum oxygen uptake (%VO2max) in obese and non-obese adolescents during various activities in standardised conditions, and the corresponding %VO2max in free-living conditions. METHODS: Twenty-seven obese and 50 non-obese adolescents aged 12 to 16 years participated in this study. Body composition was assessed by bioelectrical impedance analysis and dual energy X-ray absorptiometry (DXA), VO2max by treadmill tests, VO2 corresponding to various activities by whole body calorimetry, and time and % VO2max corresponding to various activities in free-living conditions using the heart-rate recording method and a physical activity diary. RESULTS: VO2max (l/min) was 27.4% higher in obese than in non-obese subjects (p<0.001), but not significantly different after adjustment for fat-free mass (FFM). In the whole body calorimeters, with the same activity program, % VO2max corresponding to sleep and sedentary activities were lower in obese than in non-obese girls (-15.1% and -12.3%, p<0.05), but not significantly different between obese and non-obese boys. However, walking at 4-5-6 km/h corresponded to 47-59% and 71% of VO2max, respectively, in obese, and 34-41% and 48% of VO2max in non-obese subjects (p<0.001). In free-living conditions, moderate physical activities and sports corresponded to 52% vs 35%, and 39% vs 51% of VO2max, respectively, in obese and non-obese adolescents. CONCLUSIONS: In standardised conditions %VO2max did not correspond to the same type of physical activity in obese compared to non-obese adolescents. Consequently, % VO2max is inadequate for comparing the types of physical activities of obese and non-obese adolescents in free-living conditions

Evaluation of the physicochemical and hygienic quality of cow’s milk and its derivatives in El Jadida city Morocco

Background. Despite the efforts and investments made for traceability and the guarantee of a fair and safe milk product, the informal sector threatens the safety of milk. In fact, during this circuit, the product does not undergo any treatment and therefore presents serious risks for the health of the consumer. In this context, studies have been carried out on samples of peddled milk and products derived from it. Objective. The purpose of this study is to evaluate the relevance of the informal circuit in Morocco's Doukkala region (El Jadida Province) by physicochemical and microbiological investigation of raw milk and its derivatives at various points of sale. Materials and method. 84 samples were taken between (23 for raw milk, 30 for the «Lben», and 31 for the «Raib») between January 1st, 2021 and October 30th, 2021. According to Moroccan rules, microbiological analyses revealed an extremely high non-compliance rate in most samples obtained at the level of outlets situated in the El Jadida region, with a non-compliance ratio of 65 percent for raw milk sold, 70 percent for the «Lben», and 40 percent for the «Raib». Results. Likewise, these analyses revealed that majority of the samples did not fulfill international criteria for the pH values of raw milk samples «Lben» and «Raib», which are respectively between 5.85 and 6.71; 4.14 and 4.43 and 4.5. Other characteristics, including lactose, proteins, fat, mineral salts, density, and additional water, have also yielded results. Conclusion. This has allowed us to analyze the major impact of the peddling circuit at the regional level, which is a risk factor for consumer health
