Code-switching – normal oversight on the part of bilingual speakers: A review of literature

This study was inspired by the observation that code-switching is often discouraged in foreign language schools, where the target language and native language are strictly separated, with the target language designated as the 'official' language of instruction. The study sought to examine instances of code-switching in English as a First Additional Language (EFAL) acquisition among Sesotho native speakers in the Intermediate Phase in South Africa. Furthermore, it sought to illustrate the application of tag-code-switching, inter-sentential code-switching, and intra-sentential code-switching in English First Additional Language (EFAL) education for Sesotho native speakers in the Intermediate Phase in South Africa. This paper studied a particular multilingual phenomena, code-switching. While other linguistic behaviours exist, code-switching is the most popular in additional language contexts in South Africa. This research was founded on a literature review of code-switching in additional language situations. The paper examined the three roles of code-switching: repetition, emotional, and floor-holding. It also provided instances of how tag-code-switching, inter-sentential code-switching, and intra-sentential code-switching might be utilised by Sesotho home language learners to improve their comprehension of EFAL. One finding of the study is that, similar to translanguaging, code-switching fosters a sense of belonging and ownership among learners, and it is generally more accessible for the EFAL student to acquire knowledge from familiar concepts to unfamiliar ones. Another conclusion is that learners' restricted engagement in academic activities, attributable to their inadequate language proficiency, also impacts their motivation. The study advocates for the implementation of code-switching to improve learners' classroom involvement by allowing them to utilise their native language in the acquisition of a second language. The impact of code-switching on Sesotho home language learners' comprehension of EFAL in the Intermediate Phase in South Africa remains undetermined, necessitating further investigation into this important issue.
