IMPORTANCE DES EXPÉRIENCES DANS L’ENSEIGNEMENT ET L’APPRENTISSAGE DU SYSTÈME NERVEUX AU COLLÈGE : ETUDE DE CAS

The acquisition of the concept of the nervous system is difficult for learners of 3rd year college. We asked about the possible origins of these difficulties. Our study was conducted with 12 teachers of Life and Earth Sciences and 50 learners of 3rd year college. Our results showed that the lack of conducting experiments in the classroom would be the major cause up to the introduction of false representations in learners. The Information and Communication Technologies in Education, ICT, are a good way of illustration in many disciplines. However, theses technics remain insufficient in the case of teaching and learning the nervous system, an important concept in the program of Life and Earth Sciences

ETUDE DE L’EXPRESSION DES COMPORTEMENTS MOTIVES DES ELEVES POUR L’EDUCATION PHYSIQUE ET SPORTIVE (EPS)

The motivation and determination of the many factors that cause the learners desire to learn or not, is a theme that has been widely apprehended in an educational context and sports. This study aims at knowing the various styles of behaviour of the pupils when they are justify for the courses of PES. Hundred and seventy-five pupils stemming from four public secondary establishments of Taza (Morocco), from 12 to 18 years old were subjected to an opened questionnaire evaluating their behavioural expressions according to four times which make a session of physical and sports education PSE : before the course, during the heating, during the course and after the course. The results reveal overall that when the courses of PSE interest the pupils, they express it by classifiable styles of behaviour in the order of: punctuality, the concentration, the active participation and positive emotional demonstrations of physical well-being and good mood after the courses

Development of a Survey to Assess Conceptual Understanding of Quantum Mechanics among Moroccan Undergraduates

We developed a Quantum Mechanics Conceptual Understanding Survey (QMCUS) in this study. The survey was conducted using a quantitative methodology. A multiple-choice survey of 35 questions was administered to 338 undergraduate students. Three experienced quantum mechanics instructors examined the validity of the survey. The reliability of our survey was measured using Cronbach's alpha, the Fergusson delta index, the discrimination index, and the point biserial correlation coefficient. These indices showed that the developed survey is reliable. The statistical analysis of the students' results using SPSS shows that the scores obtained by the students have a normal distribution, around the score of 7.14. The results of the t-test show that the students' scores are below the required threshold, which means that it is still difficult for the students to understand the concepts of quantum mechanics. The obtained results allow us to draw some conclusions. The students' difficulties in understanding the quantum concepts are due to the nature of these concepts; they are abstract and counterintuitive. In addition, the learners did not have frequent contact with the subatomic world, which led them to adopt misconceptions. Moreover, students find it difficult to imagine and conceptualize quantum concepts. Therefore, subatomic phenomena are still explained with classical paradigms. Another difficulty is the lack of prerequisites and the difficulties in using the mathematical formalism and its translation into Dirac notation

CONTRIBUTION A LA CONNAISSANCE DE L’ETAT ACTUEL DE LA FAUNE BENTHIQUE DE L’ECOSYSTEME ESTUARIEN DE L’EMBOUCHURE DE LA MOULOUYA (MAROC)

Moulouya is the largest river flowing into the mediterranean. A study of the current state of the benthic fish fauna of the mouth of the river was conducted between january 2014 and may 2014. The results were used to inventory 47 species divided into 04 classes. Mollusks are the most numerous, with 26 species.Crustaceans representing 33.4% of the population collected. Atyaephyradesmarestii found is the most abundant species (69,4%).This study aims at the realization of a recent taxonomic inventory (2014) wildlife estuarine ecosystem of the mouth of the moulouya (morocco). Indeed four systematic groups and 933 individuals were surveyed

DISTRIBUTION SPATIALE DE RHADINORHYNCHUS CADENATI PARASITES INTESTINAL DE POISSON TRACHINOTUS OVATUS DE LA CÔTE DE MEHDIA (MAROC)

Rhadinorhynchus cadenati and and Pomphorhynchus Francoise are two parasitic Acanthocephala Trachinotus ovatus from the Atlantic coast of Mehdia (Morroco). They always locate at the gut and they occupy almost the same habitat. Rhadinorhynchus cadenati is the most abundant and it is with great numbers, that is why we are interested to follow its spatial distribution along the intestine of host fish T. ovatus

A survey of Haemonchus contortus parasite of sheep from Gharb plain, Morocco

The study was designed to determine the prevalence of Haemonchus contortus, intestinal helminthes parasite of sheep in the Gharb plain (Morocco).A total of 1154 sheep were randomly selected from farms, pastures and abattoirs, the samples were examined using a flotation techniques for determination the eggs of Haemonchus contortus. In order to identify Haemonchus contortus among the different gastrointestinal strongyles present in mixed infections, a faecal culture was carried out for each farm and pasture. This study was carried between November 2016 and October 2017. The data were analysed with respect to sex, age, season and body condition of sheep examined. Out of (1154) samples examined, (23.92%) harbored H. contortus. Prevalence among female (30.98%) was higher than that of the males (15.63%), there was significant difference between prevalence of infection and sex (P < 0.05). Based on age group, prevalence of haemonchosis was 6.25% and 43.22% in young and aged animals respectively showing the statistical significance (P < 0.05). Seasonal variation was recorded throughout the year and was highest during spring (36.36%) and autumn (32.37%) against a low rate of 2.7% in the summer with significance difference (P < 0.05). Regarding the relationship between Haemonchosis contortus and body condition, maximum prevalence (80.83%) was recorded in animals with poor body condition, followed by those with moderate body condition (34.26%), while the lowest infestation rate (6.88%) is noted in animals with good body.

Science Teachers' Views on the Use and Effectiveness of Interactive Simulations in Science Teaching and Learning

The objective of this article is to identify and discuss the views of teachers of physics-chemistry (Ph-Ch) and Life and Earth Sciences (LES) on the use and effectiveness of interactive simulations PhET (Physics Education Technology) in student teaching and learning. A survey research method was used in this study. 114 Moroccan science teachers (67 Ph-Ch; 47 LES) at middle and high schools were surveyed. The quantitative analysis was performed to provide insight into who uses PhET simulations, why they use them, and how they are used. The data collected was analyzed using Statistical Package for the Social Sciences (SPSS) software. The results indicate that the use of interactive simulations in investigative science teaching and learning is very effective for both teachers and students, despite the presence of a set of obstacles that hinder the use of classroom simulations. The implication of this research is that the use of interactive simulations in science teaching in Morocco can enhance learning activities and help students to understand scientific concepts effectively

The Effect of Using Computer Simulation on Students’ Performance in Teaching and Learning Physics: Are There Any Gender and Area Gaps?

The aim of this study is to determine the effect of using computer simulation on students’ performance in teaching and learning physical science, particularly the electrical Ohm’s law. A sample of 182 students classified into two groups–experimental (92) and control (90)–from two middle schools in Meknes city (one in the rural area and the other urban area) was the subject of a pretest and posttest evaluation. The outcomes of the administered test to both groups of students, control and experimental, were compared and analyzed using Student’s t-test and the Mann–Whitney U test with Statistical Package for the Social Sciences (SPSS). The results obtained suggest that the experimental group register the best performances after the posttest than the control group (p0.05), the urban students were more successful than the rural ones, with and without the use of simulations. In this respect, this study recommended using and practicing simulation software to improve and develop the performance of middle school students
