Effects of the second language on the first : investigating the development of 'conceptual fluency' of bilinguals in a tertiary education context

[摘要] ENGLISH ABSTRACT:This study investigates the effect of the increased use of a second language (L2) (English) as language of teaching and learning on the bilingual individual in a specific bilingual higher education context. The specific interest is in the development of conceptual fluency, and the role that bilingualism and the increased exposure to an L2 in a teaching and learning context plays in such development. In order to serve the interest of the study, the theoretical framework includes theories developed in language and cognition, bilingualism and cross-linguistic influence. The theoretical stance that is taken in this thesis is one that: recognises that bilingual individuals cannot be expected to exhibit the same kind of linguistic and conceptual knowledge as monolinguals, investigates the possibility that language can affect certain aspects of cognition, acknowledges that bilingual individuals themselves can contribute to the knowledge about the bilingual mind.The participants in the study are L1 speakers of Afrikaans who finished their secondary schooling in Afrikaans. At university they are increasingly exposed to more English as language of teaching and learning than in previous formal education. The effects of the increased use of English on conceptual fluency, academic achievement and self-perception of language proficiency were investigated. The study used university records, language tests and interviews to collect data. No concrete evidence could be found that English has a significantly positive or negative effect on 'conceptual fluency', academic achievement or self-perception of language proficiency. The study however provided valuable information about how bilinguals use the languages they have in their repertoires. The findings from the study suggest that increased exposure to an L2 leads to a unique form of language competence. This 'multi-competence' enables the participants in the study to use both languages in the understanding and learning of concepts in their respective fields of study. Thus this dissertation provides evidence that bilinguals can transfer knowledge and skills between the languages they know. Theories developed by Cook (1999, 2003) and Jarvis and Pavlenko (2008), that suggest transfer is bidirectional, is partly supported by the findings of the study.The study has various implications for the field of bilingualism in education. It illustrates how a multilingual context such as the one we have in South Africa complicates the use of certain methodologies and theoretical frameworks. This also means that models of bilingual education designed elsewhere cannot be implemented in the South African context without considered modification.
