Abstract

The aim of this article, of a qualitative approach and descriptive-exploratory nature, was to analyze the contribution of audiovisual material made available on the YouTube platform with the participation of Ubiratan D'Ambrosio on Ethnomathematics. The procedure was a survey and selection of audiovisual material on YouTube with a speech by D'Ambrosio that included the subject of Ethnomathematics and with more than 5,000 views. Six videos, which were made available between 2013 and 2020, were selected. They have a duration varying between five minutes and two hours. The audiovisual material available contains conceptualization and discussion of Ethnomathematics, in addition to the possibility of access and comprehension in a distinctive manner utilizing digital media. According to the theorist, and based on the video analysis, Ethnomathematics is a cultural construction carried out by different groups in their daily lives in the search for survival and transcendence.
