RT Journal Article T1 Interconnections between Content Knowledge and Pedagogical Content Knowledge of a University Lecturer in Linear Algebra A1 Vasco Mora, Diana Lucía A1 Climent Rodríguez, Nuria A1 Escudero-Ávila, Dinazar Isabel AB The aim of this study is to deepen our understanding of the practice of a lecturer in linearalgebra by exploring the connections he makes between his content knowledge and his pedagogicalcontent knowledge while working on the topic of matrices. Data were collected through videorecordings of his classes and semi-structured interviews, and were analysed with the MathematicsTeacher’s Specialised Knowledge model. Instances of classroom performance, supported by theteacher’s own affirmations, provided evidence relating to the categories comprising the model, andenabled us to establish connections between the lecturer’s knowledge, his understanding of hisstudents’ learning capabilities, and his knowledge of teaching mathematics, which together accountfor his classroom practice: the use of varied examples to introduce new content, the highlighting ofthe most salient aspects of the topic, and alerts about potential errors and difficulties. The contributionthat these results could make to the training of university teachers, which would be done with theknowledge of the areas of difficulty shown by the teacher in mind, could be used to deepen otherelements of their pedagogical content knowledge. The interconnections between areas of knowledgeidentified by the study also serve to validate the usefulness of a theoretical model for studyingteachers’ knowledge PB MDPI SN 2227-7390 (electrónico) YR 2021 FD 2021 LK http://hdl.handle.net/10272/20174 UL http://hdl.handle.net/10272/20174 LA eng NO Vasco-Mora, D., Climent-Rodríguez, N., & Escudero-Ávila, D.
