Abstract This study aimed at investigating the impact of two types of strategy instruction on Brazilian learners’ planned speech performance at the level of complexity, accuracy, fluency, and adequacy. In order to do so, three groups participated in the present study: (1) the integrated group received strategy instruction during their regular English classes; (2) the isolated group received strategy instruction in a separate course; and (3) the control group received no strategy instruction. The groups also performed two narrative tasks before and after treatment, preceded by 10 minutes of strategic planning. Learners’ oral performance was analyzed and the statistical results showed that (i) the groups that received treatment outperformed the control group; and (ii) the isolated group produced more adequate and accurate speech, while the integrated groups improved their performance in terms of adequacy solely. In conclusion, one can claim that, in spite of the type of treatment, strategic planning can be enhanced by strategy instruction, shedding light on both Language Pedagogy and strategic planning research.

O campo disciplinar de Aquisição de Segunda Língua (ASL) tem observado um interesse crescente pela investigação dos efeitos dos materiais audiovisuais com legendas interlinguais e intralinguais com relação a diversos aspectos inerentes à aprendizagem/aquisição. Neste contexto, este artigo procura fornecer uma revisão sistemática da literatura que trata de aspectos da aprendizagem através do uso instrucional/experimental de materiais com legendas interlinguais e intralinguais. O presente trabalho baseia-se na literatura que se destaca no campo da ASL no que tange à interface com a legendagem aberta e fechada, ao mesmo tempo que aponta os principais objetivos e resultados oriundos destes estudos. Este artigo também objetiva desvendar quais dimensões desta interface têm merecido mais destaque acadêmico nas últimas duas décadas. Por fim, algumas considerações são feitas em relação a pesquisas futuras, levando em consideração a literatura da área e tópicos pouco investigados.

The disciplinary field of Second Language Acquisition (SLA) has witnessed an increasing interest in the investigation of the effects of subtitled and captioned audiovisual materials on domains of language learning/acquisition. In this context, this paper seeks to provide a systematic review of recent studies related to language learning aspects aided by the instructional/experimental use of subtitled and captioned materials. The present paper draws on relevant literature in the field of SLA that interfaces with subtitling/captioning, while outlining their goals and main findings. This paper also aims to unveil which dimensions have merited scholar attention the most in the last two decades. Finally, some considerations are made regarding possible avenues for future research, taking into account the existing literature and underinvestigated issues.
