Aprendizagem visível de siderurgia para estudantes do curso técnico em metalurgia

Manipulative materials applied to the principle of mass conservation in the steel balances by dismembering the molecules of the components of the ore, metals and slag were used to quantify learning related to learning styles. In this sense, mixed research methodology was used: verification of learning styles through the New Learning Styles Index (N-ILS), evidence on mass balance for calculating Effect Size, as established by the laboratory in Hattie's Visible Learning. Among the results obtained, the Effect Size calculated for the pedagogical practice stands out, which, on average, in the three classes was 0.63. A value higher than the 0.40 reference is considered a satisfactory average intervention and compatible with the Effect Size values of similar methodologies. In the qualitative part of the research, semi-structured interviews were conducted where it was possible to understand how the students perceived their learning. This study innovated when calculating the Effect Size combined with Learning Styles and contributes to the understanding of collaborative learning practices using manipulative material.
