While there is evidence that the dual language model has the potential to raise the academic achievement of English language learners (ELLs), the policies mandated through the No Child Left Behind Act do not support maintenance of the student's heritage language which is an integral part of the model. Using symbolic interactionism as a framework, this study explored the experiences of dual language elementary teachers as they operate under the authority of current educational policy. The findings, presented as a concept model, reveal the didactic behaviors exhibited by teachers and suggest a dynamic process of negotiation is at work which informs their professional identities.
