Aprendizagem formal de fonologia e seus efeitos na pronúncia dos sons vocálicos do inglês de aprendizes brasileiros

Abstract

The purpose of this study was to investigate if, and how, the metalinguistic knowledge of the phonological system of the English language affects the level of accuracy of the production of English vowel sounds by prospective teachers of English and how this knowledge enables them to monitor their own pronunciation. Specifically, the study attempted to: identify the problems English learners have when pronouncing vowel phonemes in English; investigate the level of perception the prospective teachers of English have concerning their own difficulties and problems in producing vowel sounds; analyze if the prospective teachers of English begin to more precisely identify their own problems/difficulties in the production of the vowel phonemes once they gain metalinguistic knowledge about the phonological system of English while taking the course English Language Phonology; and, finally, analyze if, and how, the metalinguistic learning of the phonological system of English helps learners to monitor their pronunciation in both controlled activities in the course English Segmental Phonology (focussing on the production of sounds) and less controlled activities in courses which focus on communicating messages, especially after a time gap between the instructed learning and spontaneous communicative production. This study is theoretically supported by McLaughlin’s Model of Information Processing (1983), Fledge’s Model of Speech Acquisition (1995), Best’s Perceptual Assimilation Model (1995), Krashen’s Monitor Hypothesis (1972), and other works which attempt to apply models of learning and of language acquisition to distance learning. In order to achieve the above mentioned objectives, portfolio activities recorded by 29 (twenty nine) prospective English teachers of the Distance English Teaching Certificate Program, at UFC-UAB, were collected while the learners were taking the following courses: English Segmental Phonology, which focuses on the production of sounds of the language, and English V: Oral Comprehension and Production, which focuses on communicating messages. An analysis of the recordings indicated: i) the most recurrent problems in the production of oral sounds result from the improper substitution of English sounds for Portuguese sounds, either because students don’t perceive their distinction or because they are influenced by the graphonemic spelling of word; ii) the students were able to perceive and correct their own pronunciation problems, which suggests that instruction on the phonological system of English allowed the students to activate and use self-monitoring strategies; iii) as the students learned about the phonology of English, they began to identify and correct their own pronunciation problems; and iv) after some time of having taken the Phonology Course, students were able to identify and correct their pronunciation problems, maintaining a 70% level of accuracy in the production of the oral sounds, even in activities which focus was not on the production of the sounds but on message communication. These results suggest that metalinguistic instruction on the phonological system of English can be helpful in the development of self-monitoring strategies and, therefore, optimize the production of oral sounds in a foreign language. The long-lasting effect of metalinguistic knowledge of phonology in the pronunciation of English can also be implied.
