The study focused the analysis on some teacher educators’ answers about MTE’s specialised knowledge. Mathematics Teachers’ Specialised Knowledge model (the so-called MTSK model) helped us to identify specific dimensions and domains of teacher educators’ specialised knowledge, identified in some mathematics teacher educators’ answers. From this information, by analysing similarities and differences and prevalent ideas, we raise hypotheses about some features that teacher educators believe as a part of MTE’s specialised knowledge. Finally, we propose an adaptation of the MTSK model that can describe the teacher educator’s specialised knowledge","PeriodicalId":438012,"journal":{"name":"Educación matemática","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125901726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The curricular program and didactic materials in probability are examined by applying the notions of epistemic and didactic configuration from the Ontosemiotic Approach to math-ematical knowledge and instruction. The results show an emphasis on the classical meaning of probability to the detriment of the intuitive and frequency meanings. This predominance of the classical meaning implies that all the situations-problems proposed in the curricular material are solved with the appli-cation of Laplace’s rule and that all the elementary events are equally likely. In this context, we identify different potential semiotic conflicts related to con-cepts-definitions, procedures, languages, and arguments that must be consid-ered by teachers when using the curricular material. In this way, professional development programs should be planned to make it possible to exploit the possibilities of the curricular materials and cover the aforementioned aspects.","PeriodicalId":438012,"journal":{"name":"Educación matemática","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125401128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
