Abstract

In this article we undertook a work of characterization of a teaching sequence in class using a pedagogy involving ICT. It is in fact a question of identifying the advantages and the limits of the latter when learning the concepts of voltage and intensity in electricity for learners of the first year of secondary school. For this, we have adopted a comparative approach between two situations of setting up a lab once without ICT and once with ICT. We asked following each step the same MCQ based fundamentally on the circuits manipulated by the learners during the TP. The results collected and analyzed statistically showed some advantages associated with ICT which can be summarized in two essential points: -Possibility to offer learners a clear representation of electric current in Ohmic conductors. Their conception of this phenomenon has become more or less realistic on the microscopic scale that experience is unable to offer. This allowed them to clearly distinguish an open mesh from a closed mesh. -Possibility of better illustrating the electric current than experience for passive dipoles in series or in derivation. However, we have also identified limits associated with the TIC coming essentially from the macroscopic aspects of the electrical phenomena which can be well illustrated experimentally. For example, the comparison of voltages at the terminals of two symmetrical dipoles.
