We present in this paper the construction of an educational low-cost teslameter and its use for the magnetic field measurement of a system containing two coils. Our framework is based on the Arduino program and Smartphone application in an educational context. As a finding, we have obtained good agreement between the experimental results and those found using the theoretical model. These results are validated by the new technology based on the integration of Arduino platform and Smartphone application.

In this study, which aims to help grade nine students overcome the misconceptions about electric current, we identified their misconceptions about this concept and then designed and implemented a playground activity as an analogy of electric current. Through the conceptual change texts approach, which we have enhanced with experience, we use this analogy to explain the scientific conception of electric current. We call the approach resulting from this combination: the Conceptual Change Text Enhanced by Experiment and Analogy (CCTEEA). This study adopts the pre-experimental method with the design of the pre and post-test, an experimental group and a control group. The comparison of students’ conceptions, before and after the intervention, demonstrated that the CCTEEA was successful in helping students to overcome misconceptions about electric current.

The recent progress of intelligent electronic devices makes computer science, electronic and information technology, highly related to teaching and learning physics. The main question is how education can integrate this knowledge. Methods and components of new technology are applicable for education also; teachers and learners used the parts and tools which were manipulated only by engineers. The popular Arduino board is a very good example that is practically an industrial microcontroller whose pins are wired to easy-to-use connectors on a printed circuit board. In this work, we have developed a simple Arduino-based platform to support experimenting and understanding of some educational concepts related to the free fall. The obtained data was automatically recorded using Excel Data-Streamer. This platform is therefore useful as a learning tool which offers students the possibility of verifying the value of the gravity intensity ‘g’, it can be also used in teaching/learning the concepts related to free fall.

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.
