In particular, we are interested in the specialized mathematical knowledge, SCK, the pedagogical knowledge related to teaching, KCT, and the knowledge of content and curriculum, KCC. We proposed to record a video to a sample of 27 primary education students enrolled in their first mathematics education course. They had to explain an arithmetic property of natural numbers using manipulative materials. PSTs do not create contexts by the mere presence of manipulative material, but only rely on it for visual purposes; the meaning of these values are modified during the explanation. Evidence has been found of difficulties relating to the SCK such as the inadequate varying of the meanings given to the manipulative material, and to the KCC such as the selecting of an unsuitable material. info:eu-repo/grantAgreement/ES/DGA/S60-23R info:eu-repo/grantAgreement/ES/MICINN/PID2019-104964GB-I00 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 0.451 2023 Education 2023 Q2 Applied Mathematics 2023 Q2 4.3 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Arnal Palacián, Mónica Universidad de Zaragoza (orcid)0000-0002-7725-3917 2006 200 Universidad de Zaragoza Dpto.
