Este artigo descreve uma forma de promover o ensino da matemática, através de um contexto formativo que envolve atividades experimentais hands-on de STEM, recorrendo ao questionamento investigativo. Com uma abordagem qualitativa de natureza interpretativa, daremos conta deste contexto formativo, dando destaque à forma como a matemática foi trabalhada, a partir do tópico do som. Serão apresentados, com mais pormenor alguns estudos de caso envolvendo professores que implementaram este tema, de forma interdisciplinar. Concluise que é possível trabalhar a matemática, a partir de STEM, ao nível do ensino básico, através de um contexto de desenvolvimento profissional colaborativo, onde os professores são apoiados na implementação das suas práticas.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract. This paper describes a way to promote the teaching of mathematics, through a professional development context that involves STEM hands-on experiments applied resorting to the inquiry approach. With a qualitative methodology and an interpretative approach, we investigate how teachers developed mathematical tasks, from the sound topic, according to school syllabus. We also present some case studies, involving teachers who implemented this theme in an interdisciplinary way. It is concluded that it is possible to work mathematics based on STEM experiments, at primary schools, through a collaborative teachers&#8217; professional development context, that supports the teachers when they implement their practices.]]></p></abstract>
