Experimental didactic proposal for inclusive teaching of waves in high school

Abstract

The models available for teaching waves, especially in high school, do not consider the stage of real development in which the vast majority of students are ^[1]. Allied to this, the difficulty in presenting frequencies, either of electromagnetic or sonorous nature, different from the bands that we can interpret through our senses, tends to constitute a huge epistemological obstacle. In an attempt to shed some light on this problem, we have developed two experiments that have relations between invisible and inaudible frequencies but which, through processing with Arduino platform, can be converted into audible frequencies. Thus, we intend to unveil this invisible world, bringing to the classroom experiments that can be used, even by students with blindness or deafness.
