GUSMAO, Tânia Cristina Rocha Silva  e  MOLL, Vicenç Font. Metacognitive analysis of a mathematics class on surface measurement. Relime [online]. 2022, vol.25, n.2, pp.169-196.  Epub 19-Jun-2023. ISSN 2007-6819.  https://doi.org/10.12802/relime.22.2522.

The objective of this study is to analyze the practices that a teacher carries out with his students to solve a surface measurement problem in which aspects of a metacognitive nature intervene. A didactic proposal was designed, based on a diagnostic teaching methodology, in which the teacher proposes a task to bring out different personal meanings about the length and surface magnitudes, using Fletcher's tangram. The instruction was carried out in a class of 26 14-year-old students who were in the 2nd year of Compulsory Secondary Education in Spain. For the analysis, constructs of metacognition and the Ontosemiotic Approach were taken as theoretical reference. Among the conclusions is that cognition and metacognition can be improved with well planned and responsibly executed instruction.
