Code-switching patterns among bilingual students in urban secondary schools

Thesis Abstract

In contemporary urban secondary schools, bilingual students frequently engage in code-switching as a natural component of their communicative repertoire, reflecting complex linguistic, cultural, and social dynamics within diverse classroom environments. Despite its pervasive presence, there remains limited empirical understanding of the specific patterns, functions, and contextual determinants of code-switching among this student cohort, which impedes educators' ability to effectively support bilingual language development and promote inclusive pedagogies. This study aims to systematically examine the patterns of code-switching among bilingual secondary school students in an urban setting, with specific objectives to identify prevalent types of code-switching, analyze contextual factors influencing switching behavior, and assess the implications for language policy and classroom interaction. Employing a mixed-methods research design, the study integrated quantitative and qualitative data collection techniques to provide a comprehensive examination of the phenomenon. The population comprised 300 bilingual students enrolled in urban secondary schools within the city, with a stratified random sampling technique employed to select a sample of 150 students representing various language pairs, including English-Mandarin, English-Hindi, and English-Spanish. Data collection instruments included structured classroom observation checklists, semi-structured interview guides, and discourse analysis of recorded classroom interactions, complemented by a bilingual language use questionnaire administered to all participants. To ensure the validity and reliability of the instruments, pilot testing was conducted, and inter-coder reliability was established for discourse analyses. Data analysis procedures encompassed descriptive statistics to outline general patterns, chi-square tests to examine associations between variables, and thematic analysis for interview data, with the use of NVivo software to facilitate coding and thematic development. The study anticipates revealing differentiated patterns of code-switching categorized into intersentential, intrasentential, and emblematic switches, with contextual factors such as classroom activity type, interlocutor status, and degree of linguistic proficiency significantly influencing switching behavior. It is expected that findings will demonstrate a functional linkage between code-switching and social identity expression, classroom participation strategies, and teacher-student rapport. Moreover, the research aims to elucidate how sociocultural norms and language policies shape code-switching practices, contributing to ongoing debates in applied linguistics and language education. By grounding the analysis in the Communicative Competence Theory and the Socio-Pragmatic Framework, the study aims to contextualize code-switching as a strategic communicative act rather than merely a linguistic deficiency. This research contributes new empirical evidence to the field by filling notable gaps regarding the socio-contextual functions of code-switching among secondary school students in an urban environment, thereby extending existing models of bilingual language use. It highlights the pedagogical implications of recognizing code-switching as a resource for facilitating learning and social integration, and advocates for policy adjustments that acknowledge multilingual realities in classrooms. The main conclusion underscores the importance of fostering an inclusive linguistic environment that respects students’ bilingual identities and supports strategic code-switching as a pedagogical resource. Recommendations include teacher training programs to enhance awareness of code-switching functions, development of language policies that valorize bilingual practices, and further longitudinal studies to explore evolving switching patterns over time, thereby advancing both theoretical understanding and practical application in multilingual education contexts.
