“…Both techniques can be implemented in order to study the electrical response of linear or nonlinear devices of practical interest in many fields of scientific research. Teaching of physics is essential for cumulative improvement in physics instruction, as well as for the extension of the quantitative methods of physics to other scientific fields, like medicine and biology [12,[16][17][18][19]. Finally, future work will be dedicated to carry out statistical studies in the presence of the students.…”

A comparison between two different techniques useful to measure the current-voltage (I-V) characteristics of conducting materials or devices will be presented, suitable for an undergraduate laboratory devoted to the electrical measurements. First, I-V curves of linear resistors with known nominal resistance are measured by using the simplest version of a DC method and an AC method, in order to settle the experimental procedure. Then, nonlinear I-V curves of a superconductor are measured with the same procedures at different temperatures down to 77K.

We aim to highlight the importance of using Huygens’ geometric model when instructing high school students about light. To achieve this, we conducted a research study on teaching lightwaves in Morocco’s secondary schools. We investigated how the place of the lightwave in this teaching affects understanding its basic concepts. We carried out a two-dimensional analysis to examine the place of the lightwave in the high school physics curriculum. We administered a test to assess the conceptual understanding of secondary school and university students. The analysis of the curricula revealed several shortcomings in the teaching of geometrical and wave optics. Furthermore, the assessment of conceptual understanding revealed that a significant proportion of students have misconceptions about the wave concepts of lightwaves and that these misconceptions persist throughout their higher education.

“…Yet the majority of students do not have this kind of understanding [1]. This is partly due to traditional teaching methods, which do not help students to develop an appropriate understanding of physical concepts [2,3], including the role of slits in the formation of the diffraction pattern [1].…”

The Arduino board and its communication with several sensors are becoming more and more popular in the physical science community. They offer inspiring possibilities for learning different physical concepts. In this article, we focused on creating a very practical educational system for experimenting with diffraction of laser light and graphically visualizing the distribution of light intensity in space, which is impossible to perform it with the devices available in the educational laboratories of physics. The main elements of this configuration are the Arduino UNO microcontroller board, the BH1750 sensor and the NEMA17 motor and its A4990 driver. The results’ graph is displayed in real time on the computer using the Data Streamer add-in. We see that the abbreviated curve corresponds well to the theory. In addition, feedback from the participants in the test activity of the device showed that they were satisfied with its operation and its contribution to the understanding of diffraction. Therefore, we believe that the device presented can play a very important role in the diffraction phenomenon learning because of its high precision and reliability in the measurements.
