Cross Language Transfer of Metalinguistic Awareness: A Meta-Analytic Structural Equation Model for Chinese-English Bilingual Children A dissertation submitted to the Graduate School of the University of Cincinnati in partial fulfillment of the requirements for the degree of Doctor of Education in Literacy/Second Language Studies Of College of Education, Criminal Justice, and Human Services by Xuejiao Diao M.Ed. University of Cincinnati, OH, USA April 2014 Committee Chair: Mary Benedetti, Ed.D. ABSTRACT While a number of studies have been conducted to investigate the construct of metalinguistic awareness in Chinese-English bilingual children, the results are conflicting regarding whether bilingualism facilitates the transfer of metalinguistic skills across English and Chinese. This dissertation was designed to offset the shortcomings of relatively small sample sizes in prior research by synthesizing prior study results using meta-analysis and meta-analytic structural equation modeling. These methods were used in order to reveal a holistic picture of the construct of metalinguistic awareness and its relationship with other moderators. Using meta- analysis, this study examined if Chinese-English bilinguals and Chinese or English monolinguals have equal performance on various metalinguistic tasks. A proposed Bilingual Metalinguistic Awareness Model was then fitted to the meta-analytic data to bring to light the best measurement model for the construct of metalinguistic awareness and its relationship with Chinese and English language proficiency, cognitive development, language instructional methods, and social influence. The dissertation analyzed data from 49 studies, including, 27 correlation matrices, and found no statistical differences between Chinese or English monolingual children and Chinese- English bilingual children in terms of metalinguistic awareness. The study also found the good fit of the measurement part of the Bilingual Metalinguistic Awareness Model. Significant correlations were identified between Chinese and English metalinguistic awareness, metalinguistic awareness and cognition. However, Chinese and English language proficiency were found not to be significantly correlated with metalinguistic awareness. The findings were interpreted in light of the heterogeneity and methodological flaws of studies included. Theoretical and pedagogical implications were also discussed. ii iii ACKNOWLEDGEMENTS I would like to take this opportunity to thank all the people who have encouraged and guided my research.
