%0 Journal Article %T Roles of Code Switching in Multilingual Public Primary Schools in Ile-Ife, Nigeria %J American Journal of Linguistics %@ 2326-0769 %D 2012 %I %R 10.5923/j.linguistics.20120103.04 %X The study investigated roles of code switching in multilingual public primary schools in Ile-Ife, Nigeria. It also determined the effects of the languages used on teaching and learning mathematics with a view to presenting code-switching as a viable medium of instruction to facilitate the development of literacy in children. The data for the study were obtained from five mathematics teachers and fifty pupils from five purposively selected primary schools through ethnographic observation and structured interviews. Data collected were analysed using Myers-ScottonĄ¯s Matrix Language Framework model, as well as descriptive and inferential statistics. The results showed that teachers in the schools used code switching, where Yoruba was the matrix language and English was the embedded language, as a communicative strategy in their classrooms. Code-switching was also found to be used as an approach to the acquisition of literacy in that it allowed each pupil to use each of his/her languages in a natural, meaningful way as the various classroom activities were being implemented. The study concluded that the use of code switching in multilingual mathematics classrooms does not result in a deficiency in learning, but is a useful strategy in classroom interaction and efficient way of transferring knowledge to students. In this case, one language might help the other, and sometimes both together may create a new idea, image, thought, behaviour, outlook, organization, and adaptation. %K Code Switching %K Language %K English %K Mother Tongue %K Multilingualism %U http://article.sapub.org/10.5923.j.linguistics.20120103.04.html
