“…On its side, Zacharia (2007) reports that replacing real experimentation with virtual experimentation during a specific part of the experiment has a positive influence on students' conceptual understanding of electrical circuits. This claim is supported by several types of research, using a simulation can develop students' understanding of physics concepts (Arias et al, 2020;Bozkurt & Ilik, 2010;Sarabando et al, 2014). (Price et al, 2018;Wieman et al, 2008) have also shown that simulation adds value by enabling activities that are not possible with classroom equipment and helps overcome logistical barriers and lack of laboratory equipment.…”

This 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.

“…This transformation is supported by a number of features: it maintains power invariance, adheres to right-handed coordinate system conventions, and follows uniform scaling principles [25], [31]. The core of this transformation is represented by the power-invariant, right-handed, uniformly scaled Clarke transform matrix defined as follows (1) To convert an abc-referenced system represented as a timedomain column vector (mabc(t)) into a corresponding timedomain column vector in the αβ0 reference frame (mαβ0(t)), the abc vector must undergo a pre-multiplication process with the transformation matrix KC, as shown in follows (2) On the other hand, to return to the abc frame (i.e., mαβ0 (t)), both sides of equation ( 2) must be pre-multiplied by the inverse of KC, resulting in as follows (3) In essence, the αβ0 transformation is a fundamental tool in electrical engineering that simplifies the manipulation of vectors between the abc and αβ0 reference frames while preserving important mathematical properties and conventions.…”

“…Vibration analysis, a core aspect of mechanical engineering, is dedicated to understanding the complex behavior of mechanical systems subjected to oscillations or vibrations due to external forces or displacements [1]. This field has deep significance in various sectors, including industry [2]- [6], automation [7]- [10], and aerospace [11], [12], as it provides a mechanism for designing, controlling, optimizing, and maintaining the performance, safety, and reliability of mechanical systems.…”

This research offers a thorough analysis of the dynamic behavior of 1-, 2-, and 3-DoF mechanical systems under a sinusoidal force, examining both mechanical and dq coordinates. By utilizing standardized initial conditions, the 1-DoF system displays fascinating oscillatory patterns with dual frequency components, highlighting the significance of low damping. The adaptation to dq coordinates simplifies the analysis and highlights the system’s nuanced behavior. In contrast, the 2-degree-offreedom system exhibits intricate interactions, oscillation phenomena, and multiple frequency components in mechanical coordinates. The contribution of masses that do not experience external forces in dq coordinates is minimal. On the other hand, the 3-degree-of-freedom system shows diverse interactions and frequency components that are different from the dq transformations. The observed dynamics not only enhance comprehension of these systems but also provide valuable insights for refining analytical approaches in the analysis of dynamic systems. This study sets the stage for future investigations and urges the development of streamlined analytical frameworks for a more focused exploration of externally influenced variables in dynamic mechanical systems.

“…A virtual lab is a simulated analog to a traditional in-person lab. The concept of a virtual lab is not new [18][19][20], and there has been evidence that virtual labs are successful in enhancing student motivation and performance [21][22][23][24]. Simulation also promotes active learning [25].…”

As technology trends continue to evolve, educators must adapt to a rapidly changing landscape. Simulation is an important component of new industry trends, allowing the design and planning of complex systems [1]. The earlier students are introduced to simulation in their degree program, the more proficient they will become. Virtual labs offer a natural starting place for students to begin learning about simulation. The challenge for educators is the time investment required to create robust models, especially if they are not familiar with the required programming languages or software. In this work, we present two resources designed to lower the barrier for incorporating a virtual lab: 1) a virtual controls laboratory and 2) a DC circuit analysis virtual laboratory. These resources provide instructors with simulations of physical systems using Simscape ™ along with detailed lab manuals to describe the process and assigned tasks. Instructors can introduce students to industry tools by both using and building models, such as PID controller models in Simulink ® or electrical circuit models in Simscape, among others. These virtual laboratories can help instructors to achieve several education goals in their classrooms simultaneously. They can 1) introduce students to simulation, 2) encourage active learning, and 3) increase students' engagement with challenging concepts, among others.
