There has been a high failure rate of Grade 10 learnersin the year end examinations in the Caprivi Education Region of Namibia over a number of years. The objective of this study was to investigate whether the use of mother tongue in English medium classrooms enhanced learners' academic achievement.The study investigated 12 teachers at 12 schools in the Caprivi Education Region. The study found that teachers perceived Code Switching as enhancing academic achievement because it enhanced learners' learning of the English language, improved the way learners answered questions, and that it enhanced teaching and learning of English as a second language. It is believed that learners would be actively involved in their learning, understand the subject matter better and the difficult English concepts would be better interpreted by learners in the language that they fully understand.

Outapi is a rural town in the northern part of Namibia. Its residents are exposed to a variety of languages. Speakers whose English proficiency is limited, but who are able to communicate in Oshiwambo, use Oshiwambo to communicate. The problem arises when communication is in English, as the majority are English second or third language speakers and thus unable to express themselves very well. This study sought to understand the role of code switching between English and Oshiwambo by Outapi residents and public officials when conducting public affairs in the bank, the clinic and the post office. A qualitative research approach based on a case study research design was applied to determine the pertinence of code switching in the multilingual community. Findings from observations and interviews revealed that code switching facilitated communication in Outapi for speakers to attain their communication goals. Although the study indicated how code switching enriches Oshiwambo in terms of vocabulary, it also indicates a contribution to the language death of local languages.
