The positive meaning of the use of Interactive Simulation eduMedia in the subject of Light Waves in Secondary School in Morocco
No full textThis work aims to study the impact of the use of the interactive simulation eduMedia, on the understanding and learning of Moroccan students in the qualifying secondary of the second year of the scientific baccalaureate option physical sciences at the high school Abdellah Laroui of the city of Fez. Using the pre-test and post-test methodology with a simulation group (24 students) and an experiment group (24 students) during the school year 2021-2022, the data were then analyzed using the IBM SPSS 21 statistical analysis program, for the analysis of quantitative data, Mann-Whitney U tests of independent samples were used. The results of the descriptive statistics show that the use of interactive simulation and laboratory experiments achieve similar objectives in the study of light waves. At the end of the session, we invited the students of the simulation group to answer the survey questions, moreover, the qualitative data were processed by the SPHINX v5 software. In addition, through interviews, we asked the six teachers to give their opinions on the use of simulation in learning, the results obtained showed a considerable improvement in some other indicators such as motivation and interaction between students compared to the classical method. The results of this research aim to better understand the opinion of teachers and students on the integration of interactive simulations in the school curriculum and may encourage the authorities of the Ministry of National Education, Vocational Training to adopt the interactive simulation program
The Added Value of Integrating the Electronics Workbench Simulator in the Teaching of Electrical Concepts to Moroccan High School Students
Full text linkIn this paper, we are interested in the study of the use of the Electronics Workbench (EWB) simulator in the study of amplitude modulation and demodulation. We conducted a study with 50 Moroccan students in the second year of the scientific baccalaureate option physical sciences at the high school Abdellah Laroui of the city of Fez. Using the pre-test and post-test methodology with an experimental group (25 students) and a control group (25 students). The results of the two groups are analyzed using the student t-test. The results obtained in the post-test show that the average of the test administered to both groups, control (MG-Con) and experimental (MG-Exp), found a non-significant difference (MG-Exp - MG-Con = 15,36- 15,08 = 0,28 > 0. In addition, using interviews, we asked students and teachers to give their opinions on questions about the use of the Electronics Workbench (EWB) simulator in learning. The results obtained show that the laboratory experiments cannot replace the simulator (EWB) which can be used as an alternative pedagogical means to help students understand the concepts in electricity
Influences of the effective use of a computer simulation on learning in physical science
Get PDFOne of the most attractive instruments in science education is digital simulation. The investigations were conducted utilizing a pre-test and post-test methodology with Moroccan students enrolled in the second year of the natural sciences option secondary certificate at the Abdellah Laroui High School in the city of Fez. In this paper, we assess the effects of including a digital simulation on high school students’ understanding of RLC (a linear circuit containing an electrical resistance, an inductor, and a capacitor) (25 students). There is a substantial difference between the means of the tests administered to the control (M-Cont) and experimental (M-Exp) classes (M-Exp-M-Cont=15.32–3.08=2.24>0), based on a student’s analysis of the two classes’ test scores using a t-test. This study found that using a digital simulation in an educational setting allows for the acknowledgment of the added value and has a favorable impact on student learning, notably in the study of free oscillations in an RLC circuit
Computer-Assisted Experimentation in Physical Science Education for Moroccan Students
No full textCAEx (Computer-Assisted Experimentation) enables real-time experiments to be carried out using a computer; it includes data acquisition and sensor systems, as well as real-time measurement of numerous physical properties. The use of computer-assisted experimentation in the teaching of physics and chemistry in Moroccan secondary schools underwent significant development in 2009. We conducted an exploratory study of 122 physics teachers in Morocco, from the Fez-Meknes Regional Academy of Education and the Casablanca and Guercif provincial directorates, during the 2021-2022 school year. This study was carried out using an anonymous questionnaire. We undertook this study to evaluate the use of computer-assisted experimentation (CAEx) in physics teaching, particularly in secondary schools. The aim was to understand the reasons why some teachers make only limited use of CAEx, despite its supposed pedagogical richness. The data collected in our study, processed using SPHINX V5 software, revealed that most of the teachers surveyed were convinced of the pedagogical benefits of CAEx in the classroom. However, the overall results also confirmed the limited use of this technology. This contradiction is mainly explained by several factors, such as the lack of hardware in secondary schools, the absence of specialised software, student overload, the lack of teacher training and the failure to regularly maintain equipment. The results of this study are important because they highlight the obstacles to the more widespread and effective use of computer-assisted experimentation (CAEx) in physics teaching in Morocco. These obstacles include problems of infrastructure, training, and the availability of the necessary resources. Understanding these challenges is essential for education officials and policymakers, as it could guide the investments and reforms needed to improve science teaching in Moroccan secondary schools
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
