This paper examines the concept of languaging (Swain, 2006) in the context of form-focused instruction and its role as an important tool for Brazilian foreign language learners, both at advanced level and at elementary level, if linguistic precision is the target. Supported by the Vygotskian sociocultural theory of mind (Vygotsky, 1978) and based on studies developed by Swain (2006) in the Canadian context and by Vidal (2003) in the Brazilian scenario, both with advanced learners, the paper shows how Brazilian learners of English of different levels of proficiency and from different instructional realities benefit from languaging _ the process of making meaning and shaping knowledge and experience through target-language use. A qualitative analysis of both collaborative dialogue and corrective feedback provide evidence for the claim. It is suggested that form-focused instruction via conscious reflection on language use seems to be a very attractive pedagogical resource to help learners EFL to develop their interlanguage further as well as it serves language learning
