Disponível em: <https://www.revistas.ufg.br/sig/article/view/3743/3505>.0103-7250http://repositorio.bc.ufg.br/handle/ri/14648This article discusses the role of L1 in the development of L2 competence as well as in the acquisition of knowledge. It is argued that language teaching pedagogy would benefit by paying attention to the use of L1 in the L2 classroom, especially in the case of whole schooling through L2, rather than concentrating primarily on the ideal monolingual model. The scenery that motivated these reflections is an ESL classroom of an English immersion school located in the central part of Brazil.porAcesso AbertoAquisição de L2Competência bilíngüeEscolarização bilíngüeL2 acquisitionBilingual competenceBilingual schoolingArtigo10.5216/sig.v16i2.3743
