(2016) The magnitude of code switching and code mixing in radio presentations in Tanzania: a case study of selected radio stations in Dar es Salaam region, Master dissertation, University of Dar es Salaam, Dar es Salaamhttp://41.86.178.5:8080/xmlui/handle/123456789/9531Available in print form, East Africana Collection, Dr. Wilbert Chagula Library, Class mark (THS EAF P115.3.T34P47)Code switching (CS) and code mixing (CM) have been found to be common practices in people’s communications in bilingual and multilingual communities. This study was carried out to examine the magnitude of CS and CM in radio presentations in Tanzania. The study was guided by three objectives which included: to assess the magnitude of CS and CM in radio presentations, to find out the factors that motivate CS and CM among radio presenters and to examine the perceptions of radio presenters and listeners towards CS and CM in radio presentations. The data were gathered using three methods which include questionnaires, interviews and voice recording. The findings show that both listeners and radio presenters recognised the presence of CS and CM in radio presentations. The findings further indicate that the magnitude of CS and CM in radio presentations was generally high whereby the switching and mixing primarily involved Kiswahili, the national language in Tanzania and English, the foreign language. In terms of the factors that motivate CS and CM, the study found that radio presenters used CS and CM in order to reach a wider audience, make clarifications, emphasize, make quotations, enhance solidarity and for euphemism. Furthermore, the study revealed that the use of CS and CM in radio presentations was supported as helpful by both radio presenters and listeners as they showed positive attitudes towards the existence of the two phenomena. On the basis of the findings, this study recommends that CS and CM should be recognised because they facilitate the understanding of the message being presented. Second, planners of the media language policy at both national and radio station levels should review the media language policy to allow the use of CS and CM due to the roles the two phenomena play in enhancing communication between radio presenters and listeners through radio presentations.enCode switching (Linguistic)Radio presentationRadio stationsDar es Salaam regionTanzaniaThesis
