ACRONYMS SILL Strategy Inventory for Language Learning IELTS International English Language Testing System CHAPTER 1: INTRODUCTION 1.1 Statement of the problem and rationale for the study “Give a man a fish and he eats for a day Teach him how to fish and he eats for a lifetime” (Wenden, 1985, cited in Griffiths, 2003, p.1) In the context of language learning and teaching, this saying may mean that if students are provided with answers, they can solve the problem immediately; but if they are taught strategies to figure out the answers themselves, they can face with any problem now and then, or “they may be empowered to manage their own learning” (Griffiths, 2003, p.1) Aware of the significance of the “How” rather than the “What”, recent research in second language acquisition has swerved attention from the products of language learning to the processes in which learning takes place (Oxford, 1990) The potential relationship between how students perform the task sand how successful they solve the tasks was explored in Rubin (1975) and Stern (1975) Later, scholars such as Oxford (1990), Wenden (1991), Cohen (1998) and Chamot (2004) have also suggested that learners might be able to learn language more effectively thanks to the use of learning strategies The concept of using strategies to facilitate the learning process is not new In secondary school, for example, the researcher was instructed to remember the phrase OSSACOMP, which indicates the order of adjectives before a noun (O-opinion, S-size, S-shape, A-age, C-color, O-origin, M-material, P-purpose) There have existed other general learning strategies given by almost teachers, such as listening to music, watching movies in English, highlighting main ideas, summarizing the lesson, etc However, all these strategies not make sense without the implementation of learners Gage and Berliner (1992, p.302, cited in Griffiths, 2003, p.4) suggests that the effectiveness of such strategies may require the learner to be “more active cognitively” than a learner who is less strategically involved in the task Under the cognitive perspective, language learners are considered as “an active participant in the learning process, using various mental strategies in order to sort out the system of the language to be learnt” (Williams and Burden, 1997, p.13, cited in Griffiths, 2003, p.3) To put it simple, learners hold great responsibility for carrying out learning strategies successfully, contributing to the language development Nevertheless, according to Larsen-Freeman (2001), the contribution of learners to the learning process is still underestimated This is the another reason, which triggers the researcher to investigate more about what strategies learners employ and how they with those strategies to achieve success In fact, some learners acquire knowledge more quickly and efficiently than others This discrepancy among weaker learners and stronger learners in second language acquisition stems from the cognitive, affective, and sociocultural factors to which the learners are imposed during the language learning process (Nisbet et al., 2005) Among these factors, learning strategies stands out as a subjective factor They have become a means of achieving learners‟ autonomy in the process of language learning (Oxford, 1990; Benson and Voller, 1997 as cited in Rahimi et al., 2004) Valuable work has been and continues to be done on learning strategies; however, existing research has mostly focused on learners‟ strategies use in second language contexts (Rihami, 2004) In English as a foreign language (ELT) contexts, research on language learning strategies has mainly been conducted in South East Asia, especially China (Nisbet et.al, 2005; Feng 2010; Wu, 2010), but has not been widely studied in Vietnamese contexts This creates the motivation for the researcher to conduct a study on language learning strategies by Vietnamese students in a Vietnamese context A great body of research confirms the relationship between learners‟ language learning strategies and their English proficiency (Park, 1997; Dreyer and Oxford, 1996; Peacock and Ho, 2003; Nisbet et al., 2005; Adbullah and Seyyed, 2012) However, there has been conflict in the scholars‟ opinion regarding the learning strategies used by good language learners and bad language ones Some claims that good language learners use particular strategies – which can hardly be found in bad language learner‟s cases – to assist them in mastering new language skills (O‟Malley, Chamot, Stewner-Manzaranes, Russo and Küpper, 1985, p.557-558 cited in Saricoban & Saricaoglu, 2008) However, Hişmanoğlu (2000) claims that bad language learners may use the same language learning strategies as the good ones without becoming successful This study is, therefore, conducted to compare the status quo concerning the relationship between proficiency and language learning strategy use in Vietnam with that in other countries For the four main reasons, further research into the language learning strategy use of language learners in Vietnamese context, specifically fourth-year students at the Faculty of English Language Teacher Education, University of Languages and International Studies, Vietnam National University – those who specialize in the English language for at least four years and are expected to become teachers – is needed The researcher, therefore, has decided to conduct an investigation into the relationship between this group of students‟ language learning strategies and their English proficiency This study is a step in the learning strategy Analysis from “plus” strategy items indicated that proficient learners put more focus on reading and witting extensively, and learning and using vocabulary “Base” strategies included a group of 10 strategy items Three out of ten “base” strategies relate to vocabulary, reflecting emphasis on memorization Another three strategy items fall into affective strategies involved in managing emotions The last but not less important feature is that social strategies concerning interaction with others was not found among “plus” strategies but found in “base” strategies A positive significant relationship was discovered between English proficiency and reported frequency of language learning strategy use (r > 0.5, p < 0.01) Proficiency levels had a large effect on the use of cognitive strategies; a medium influence on the use of memory, compensation, and metacognitve strategies; and a small impact on the use of social and affective strategies However, only 31.2 % of the language strategy use was accounted for by the English proficiency level Other influential factors, according to interview data, may be learners‟ studying motivation, gender, learning and teaching condition In terms of key strategies employed by students from Basic and Proficient groups, it appeared that proficient students were inclined to utilizing learning strategies under the communicative perspective with more focus on nonacademic materials whereas basic students were subject to academic materials within the conventional approach 73 5.2 Contributions of the study On a broad scale, this study added one more picture reflecting language learning strategy use by students in Vietnamese context into the world of pictures reflecting language learning strategy use by students in other nations One a narrow scale, this study provided a relatively deep understanding of language learning strategy use by fourth-year students at FELTE, ULIS as well as the relationship between their English proficiency levels and learning strategy use Through the findings of this study, students, teachers and educators are aware of the difference in learning strategy use by low-level students and highlevel students in FELTE Each individual student was informed of their own language learning strategy preference and the variety of strategies utilized by their peers Especially, low-level students can learn from high-level students by applying and adapting the language learning strategies effectively employed by proficient students Teachers and educators may use the information concerning language learning strategies preferred by proficient students as guidance for their learning strategy instructions In addition, the correlation between language learning strategy use and English proficiency level helps to confirm the positive relationship between language strategy use and academic achievement Therefore, students can fully understand the significance of learning strategy use Last but not lease, the discovery of studying motivation‟s influence on students‟ strategy use indicates that the teacher should pay more attention to the motivation which can promote and intensify language learning Internal interest 74 is a significant factor triggering and enhancing students‟ learning enthusiasm, which really affect their purposes of language learning Consequently, teachers should foster students‟ interest in the target language 5.3 Limitations of the study No single research can be labelled as a “perfect” or “faultless” one and this research paper is of no exception The first limitation of the study lies in the inadequacy of population In total, there are 86 fourth-year students with the Ielts score from 6.5 to 7.8 and 19 ones with the Ielts score from 2.6 to 4.0 However, this study included only 87 students The findings typical of these 87 students may be generalizable to the whole fourth-year students but with a lower level of reliability Another limitation belongs to the nature of the SILL questionnaire: strategy items somewhat overlap and not cover all aspects of each strategy sub-group; therefore, a complete picture of language learning strategy use could not be mirrored Furthermore, data mainly stemmed from students‟ self awareness of their learning strategy use A more objective approach towards the research methodology (i.e observation or learning diary) should have been employed in the interests of an unbiased understanding of students‟ strategy use The last limitation falls into the mere use of a “standard” Ielts test to determine the proficiency level of participants The use of a single assessment tool can not assure the reliability of results Student A may be better at studying English than student B but A may not perform as well as B in the Ielts test The grouping of students A and B in different proficiency groups may mislead the findings of the study 75 5.4 Suggestions for further research From the aforementioned limitations, other researchers when conducting related topic should bear in mind the adequacy of population, the limitation of SILL questionnaire, the combination of various research methods and the assessment tools for proficiency levels In addition, this study raised some questions which might provide fruitful areas for further research: Other researchers may conduct the study in different settings, for example, where there are more equal numbers of male and female students, where there is a mixture of students from different nations, where there is a bigger gap in age among participants The findings from this study will then be checked in comparison with those from other contexts A longitudinal project, also suggested in Carol (2003), should be set up on a long-term basis investigating issues of strategy development over time in relationship with students‟ proficiency levels Further research may be done to thoroughly discover the potential factors which may affect students‟ language learning strategy use or discover a system of strategy instructions for training students to use language learning strategies effectively 76 REFERENCES
