This dissertation in teacher leadership represents original, independent research that investigated bilingual language instruction of an indigenous Alaskan group of students. Ethnographic research using qualitative and quantitative data was applied to develop an understanding of correlations between the value of English and Yup'ik language and dual language classroom protocol and pedagogy. This research included cultural insight into the history of language transition, influence of Westernized educational system, and teachers' and community members' attitudes toward bilingual instruction. Dual language enrichment model instruction and teacher efficacy in dual language pedagogy were assessed based upon 3rd grade student reading proficiency outcomes. Observational and interview data provided insight into factors affecting language instruction. [The dissertation citations contained here are published with the permission of ProQuest LLC.
