In 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.

One 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.
