Distinctive Features of Mathematical Language Formation in the Context of Bilingual Education

This article discusses distinctive features of formation and development of mathematical language among students of educational institutions with native (Yakut) language of instruction (case study of the Sakha Republic (Yakutia). The article showcases the results of a study investigating the organization of bilingual educational process in the field of mathematical education. It reveals the psychological and pedagogical conditions conducive to successful formation of mathematical language among school students. The authors have studied a project of a bilingual mathematical dictionary for fifth-sixth forms, developed within the project of the Institute of National Schools of the Sakha Republic (Yakutia) 'Two Languages - Two Wings'. The dictionary will be an effective tool for implementation of the transitional model of bilingual education. The article also provides the results of experimental work to identify the level of formedness of mathematical language based on native (Yakut), and non-native (Russian) languages.
