OLIVEIRA, Regina Célia Barbosa de; MELO, Carla Carvalho de  and  SOUZA, Agilson Nascimento de. Implications of experimentation as a contribution to problematized activities in understanding the corrosion phenomenon. Ensino em Re-Vista [online]. 2021, vol.28, e043.  Epub June 29, 2023.

This study comprises an investigation of the teaching-learning process regarding chemical concepts in a group of basic education students, in order to analyze experimentation contributions in problematizing activities, focused on the meaning of chemical concepts associated with corrosion. Audios from semi-structured interviews and participant observations were recorded and qualitatively analyzed. The observed participant relationships demonstrated links between chemical content and the corrosion theme, advancing the understanding of this phenomenon, suggesting knowledge (re)construction and connections with other contexts, enhancing student learning development, in the context of abstraction of the investigated subject. Therefore, the applied teaching strategy contributed to cognitive and argumentative processes, in which experimentation was conducive to articulations between chemical knowledge and the studied context from interactions promoted by problematization, allowing students to reach conceptual significance.

Keywords : Experimentation; Problematization; Conceptual significance; Corrosion.
