Trang 1PART I : INTRODUCTION1 Rationale
Our students are often frustrated with trying to learn new words We cannot count howmany times the students have come up to us to express their frustration with vocabularywhen they say things like, “I have such a high level of vocabulary in my language, so it isvery frustrating that I can’t express myself as well in English What can I do? How can Iincrease my vocabulary?” or “Why is my use of this word awkward? How can I use newwords that I learn?” or “I need to use my dictionary How can I read without using mydictionary? - It’s too hard!” We hope by teaching them the strategies of elaboration it willhelp them with learning vocabulary and minimize some of their frustrations
Vocabulary is an essential constituent of second language acquisition and is of greatsignificance to language learners Without words that are the building blocks of a
language, a speaker cannot convey the intended meaning "Learning the most frequent 2 3,000 words in a language provides a firm basis of about 80 percent of the words likely tobe encountered” (Carter, 1988, p.166) Learning vocabulary is the important basis to gain
-all other skills Vocabulary deficiency leads to poor reading comprehension, poor listeningcomprehension, poor writing performance, poor conversational competence and poorgrammatical knowledge Thus, vocabulary learning is one of the major challenges foreignlanguage learners face during the process of learning a language One way to alley theburden is to assist students in becoming independent learners during the process of L2vocabulary learning To do this task, we have to know the strategies that the learners areusing as well as the effectiveness to teach suitable vocabulary learning strategies (VLS)
because learning strategies instruction can help “EFL learners become better learners Inaddition, skill in using learning strategies assists students in becoming independent,confident learners” (Chamot, 1999, p.1).
Psychologists, linguists, and language teachers have been interested in VLS for a longtime Numerous studies have been conducted comparing the retention effects of differentvocabulary presentation strategies In fact, the vocabulary field has been especiallyproductive in the last two decades We have seen a number of classic volumes on theories(e.g., Carter, 1987; Carter & McCarthy, 1988; Mc Carthy, 1990; Nation, 1990), researches
Trang 2(e.g., Arnaud & Bejoint, 1992; Gass, 1987; Meara, 1989; Nation & Carter, 1989), andpractical tips (e.g., Gairns & Redman, 1986; McCarthy & O'Dell, 1994) Recent volumesshed significant light upon different aspects of vocabulary acquisition include Huckin,Haynes, and Coady (1993), Harley (1995), Hatch and Brown (1995), Coady and Huckin(1997), Schmitt and Mc Carthy (1997), Atkins (1998), Wesche and Paribakht (1999), Read(2000), Schmitt (2000), and Nation (2001) These researches solved the present problems.Hence, based on the significance attributed to VLS in the process of vocabulary learningand enhancement, this research aims at studying on the effectiveness of CognitiveStrategies (CS) in learning vocabulary.
2 Aims of the study
The aim of this study is to introduce CS into vocabulary learning syllabus at Nghe AnContinuing Education Center (NACEC) so that we can examine the effectiveness of thosestrategies and to elicit students' opinions about the application of CS From these aims, thisstudy was an attempt to meet the need of the students at NACEC for an alternative way toimprove their vocabulary learning ability It was expected that the results of this studywould serve as a useful source of reference for the teachers and administrators at NACEC.To gain the aims which are mentioned above, this study was designed to test the followinghypothesis:
H1: Students who take part in the application of CS in learning vocabulary will make moreimprovement in vocabulary ability than those who do not participate in such a program.
The acceptance of this hypothesis would result in the rejection to the following nullhypothesis or vice versa:
H0: There is no difference in vocabulary proficiency as measured by a proficiency testbetween students who take part in the experiment program and those who do not.
In order to draw the conclusion on which hypothesis would be accepted, the answers to theresearch questions presented below would be found:
Is there a significant difference in using CS to learn vocabulary between the controlgroup (students who do not participate in applying program of CS) and the experimentalgroup (students who participate in the program)?
Trang 3 Do CS make the students' vocabulary learning ability improved?
What are the students' opinions about CS and their suggestions for future programs?The first and the second questions are the focal points The answer to them would yieldempirical evidence for the effectiveness of CS in learning vocabulary The answer to thelast question would provide invaluable information about students' evaluation of CSnecessary for further application
3 Scope of the study
Given the time constraint, the study was conducted on the 1st non-English students atNACEC only The thesis limited itself to the experimental research of CS in learningvocabulary to find out their effectiveness This means the study was not extended tomeasure students' common VLS Therefore, data for analysis were collected from thosestudents in the researcher's hope of gaining a better understanding of the issue inconsideration.
4 Method of the study
The main research method employed in this study to find out the answers to the proposedresearch questions within the scope of the study is a quasi-experimental design whichinvolves the three basic components of experiments as presented by Selinger andShohamy, that is, the population (1st students at NACEC), the treatment (CS) and the
measurement of the treatment (t-test) (1989, p.136).
Beside this main method, a questionnaire was also delivered to the students taking part inapplying program of CS as a complementary tool to obtain their feedback on the programand their suggestions for future programs.

CHAPTER 1: LITERATURE REVIEW
1 Language Learning Strategies
1.1 Background of Language Learning Strategies
There has been a prominent shift within the field of language learning and teaching overthe last twenty years with greater emphasis being put on learners and learning rather thanon teachers and teaching In parallel to this new shift of interest, how learners process newinformation and what kinds of strategies they employ to understand, learn or remember theinformation has been the primary concern of the researchers dealing with the area offoreign language learning So, language learning strategies (LLS) for foreign languagelearning and the teacher's role in strategy training is very important
Research into LLS began in the 1960s Particularly, developments in cognitive psychologyinfluenced much of the research done on LLS In most of the research on LLS, the primary
concern has been on “identifying what good language learners report they do to learn asecond or foreign language, or, in some cases, are observed doing while learning a secondor foreign language.” (Rubin and Wenden 1987:19) In 1966, Aaron Carton published his
study entitled “The Method of Inference in Foreign Language Study”, which was the firstattempt on learner strategies After Carton, in 1971, Rubin started doing research focusingon the strategies of successful learners and stated that, once identified, such strategiescould be made available to less successful learners Rubin classified strategies in terms ofprocesses contributing directly or indirectly to language learning Wong-Fillmore (1976),Tarone (1977), Naiman et al (1978), Bialystok (1979), Cohen and Aphek (1981), Wenden(1982), Chamot and O'Malley (1987), Politzer and Mc Groarty (1985), Conti and Kolsody(1997), and many others studied strategies used by language learners during the process offoreign language learning
1.2 Definition of Language Learning Strategies
The term strategies, in the second-language-learning sense, has come to be applied to the
conscious moves made by second-language speakers intended to be useful in eitherlearning or using the L2 Strategies can be very different in nature, ranging from planning
Trang 6the organization of one's learning (a metacognitive learning strategy) through usingmnemonic devices to learn vocabulary (cognitive learning strategies) and rehearsing whatone expects to say (a performance strategy) to bolstering one's self-confidence for alanguage task by means of “self-talk” (an affective strategy)
A learning strategy is a series of actions a learner takes to facilitate the completion of alearning task A strategy starts when the learner analyzes the task, the situation, and what isavailable in his/her own repertoire The learner then goes on to select, deploy, monitor, andevaluate the effectiveness of this action, and decides if he needs to revise the plan andaction.
Ever since Naiman et al (1976) noted that “good” language learners appeared to use alarger number and range of strategies than “poor” language learners, the implications ofunderstanding strategy use have seemed increasingly important However, there are stillmany questions to resolve Does strategy use actually aid language learning, or is it justsomething that good learners do? Are some strategies better than others, or is it the numberand range of strategies used that counts? Are there “bad” strategies that actually makinglearning or performance worse? Can “poor” language learners benefit from being taughtthe strategies that “good” learners use, or do you need to be a good learner already to usesome of the strategies? Does strategy training affect language learning, and if so is theeffect direct, or does such training serve mainly to raise motivation and awareness? Iflearners are encouraged to use strategies to organize their own learning, for example, whatare the implications for the role of the classroom teacher? Such issues have alreadyprompted a considerable volume of research and writing, and directly or indirectly made asignificant impact on language learning, at least in some places For example, theestablishment of self-access centers and the encouragement of learner independence areessentially based on the assumption that students will be able to use viable metacognitive
learning strategies Ellis (1994) writes: "The study of learning strategies holds considerablepromise, both for language pedagogy and for explaining individual differences in secondlanguage learning It is probably true to say, however, that it is still in its infancy For thisreason, perhaps, discussions of learning strategies typically conclude with the problemsthat have surfaced and that need to be addressed before progress can be made” (p 558)
Trang 7So far, the term LLS has been defined by many researchers But few seem to agree on whata language strategy actually is (Bialystok, 1983) because each researcher has definedstrategy within the context of his or her own study Learning strategies are defined by
O'Malley and Chamot (1990) as “special thoughts or behaviors that individuals use tocomprehend, learn, or retain new information” (p.1) while Oxford (1994) definesstrategies as “actions, behaviors, steps, or techniques students use, often unconsciously, toimprove their progress in apprehending, internalizing, and using the L2” (p.1) Rubin' s
(1987) view of strategies relates more to how they might contribute directly to L2development, while Stern (1983), concerned more with the observability of strategies,describes a strategy as a general approach to learning by the individual learner and
“techniques” as “particular forms of observable learning behaviors” Richards and Platt(1992:209) stated that learning strategies are “intentional behavior and thoughts used bylearners during learning so as to better help them understand, learn, or remember newinformation” Faerch Claus and Casper (1983:67) stress that a learning strategy is “anattempt to develop linguistic and sociolinguistic competence in the target language”
All language learners use LLS either consciously or unconsciously when processing newinformation and performing tasks in the language classroom Since language classroom islike a problem-solving environment in which language learners are likely to face new inputand difficult tasks given by their instructors, learners' attempts to find the quickest oreasiest way to do what is required, that is, using LLS is inescapable
1.3 Classification of Learning Strategies
In the 1980s and early 90s, research mainly focused on categorizing the strategies found inthe studies of the previous decade As a result, several taxonomies were proposed toclassify them, including classifications of LLS in general and language sub-skills strategiesin particular
One of the most famous to date that proposed by O'Malley and Chamot (1990) Theirhierarchical framework of strategies distinguishes three major strategy types:
Metacognitive Strategies Cognitive Strategies Socio-affective Strategies
Trang 8O'Malley and Chamot's framework of strategies has considerable intuitive appeal andmany practitioners have used this taxonomy in planning their teaching However, O'Malleyand Chamot have never examined the construct validity of their taxonomy As a result, it isunclear enough to teach students and to train them to use these three separate strategies. According to Rubin, there are three types of strategies used by learners that contributedirectly or indirectly to language learning These are:
Learning Strategies
Communication Strategies Social Strategies
According to Stern (1992:262-266), there are five main LLS These are as follows: Management and Planning Strategies
Direct strategies
Memory strategies Cognitive strategies Compensation strategies
Indirect strategies
Metacognitive Strategies Affective Strategies Social Strategies
Trang 9It can be seen that much of the recent work in this area has been underpinned by a broadconcept of LLS that goes beyond cognitive processes to include social and communicativestrategies
1.4 The importance of Language Learning Strategies in Language Learning and Teaching
Bridging the gap between students’ learning styles and teachers’ teaching styles will be apowerful means to guide students towards successful learning Thus, teaching studentslearning strategies should not be neglected Oxford (1990) describes learning strategies as
“specific actions taken by the learners to make learning easier, faster, more enjoyable,more self-directed, more effective, and more transferable to new situations” (p.8).
Learning strategies will compensate for the weakness of a learning style and maximize thestrengths of a learning style powerfully.
To emphasize the importance of LLS, Chamot et al (1999) stated, “Differences betweenmore effective learners and less effective learners were found in the number and range ofstrategies used, in how the strategies were applied to the task, and in whether they wereappropriate for the task” (p.166) Therefore, teaching learning strategies is especially
useful for the latter learners If they can find effective strategies, they will be able tosuccessfully, through effective strategy teaching, students will acquire not only vocabularybut also the way for studying.
The language learner capable of using a wide variety of LLS appropriately can improve his
language skills in a better way According to Oxford (1990), memory strategies “helpstudents store and retrieve new information”, cognitive strategies “enable learners tounderstand and produce new language by many different means”, compensation strategies“allow learners to use the language despite their often large gaps in knowledge” (p.37),metacognitive strategies “allow learners to control their own cognition - that is, tocoordinate the learning process by using functions such as centering, arranging, planning,and evaluating”, affective strategies “help to regulate emotions, motivations, andattitudes” and social “help students learn through interaction with other” (p.135).
Developing skills in three areas, such as metacognitive, cognitive, and socio-affective canhelp the language learner build up learner independence and autonomy whereby he cantake control of his own learning Lessard-Clouston (1997:3) states that LLS contribute to
Trang 10the development of the communicative competence of the students Being a broad concept,LLS are used to refer to all strategies foreign language learners use in learning the targetlanguage and communication strategies are one type of LLS As Oxford (1990:1) stated,
LLS “ are especially important for language learning because they are tools for active,self-directed movement, which is essential for developing communicative competence”.
Besides developing the communicative competence of the students, teachers who trainstudents to use LLS can help them become better language learners Helping studentsunderstand good LLS and training them to develop and use such good LLS can beconsidered to be the appreciated characteristics of a good language teacher Research intothe good LLS revealed a number of positive strategies so that such strategies could also beused by bad language learners trying to become more successful in language learning.However, there is always the possibility that bad language learners can also use the samegood LLS while becoming unsuccessful owing to some other reasons At this point, itshould be strongly stressed that using the same good LLS does not guarantee that badlearners will also become successful in language learning since other factors may also playrole in success.
1.5 The factors influencing the choice of L2 learning strategies
When a person approaches a relatively challenging task, he adopts certain strategies tosolve the problem This problem-solving process is constrained by the learning contextwhere the problem is being tackled Language learning in general and vocabularyacquisition in particular are such problem-solving tasks at different levels of complexity.The strategies a learner uses and the effectiveness of these strategies very much depend onthe learner him/herself (e.g., attitudes, motivation, prior knowledge), the learning task athand (e.g., type, complexity, difficulty, and generality), and the learning environment (e.g.,the learning culture, the richness of input and output opportunities)
Oxford (1990) synthesized existing research on how the following factors influence thechoice of strategies used among students learning a second language:
Motivation: More motivated students tended to use more strategies than less motivated
students, and the particular reason for studying the language (motivational orientation,especially as related to career field) was important in the choice of strategies
Trang 11 Gender: Females reported greater overall strategy use than males in many studies
(although sometimes males surpassed females in the use of a particular strategy)
Cultural background: Rote memorization and other forms of memorization were more
prevalent among some Asian students than among students from other culturalbackgrounds Certain other cultures also appeared to encourage this strategy amonglearners
Attitudes and beliefs: These were reported to have a profound effect on the strategies
learners choose, with negative attitudes and beliefs often causing poor strategy use or lackof orchestration of strategies
Type of task: The nature of the task helped determine the strategies naturally employed
to carry out the task
Age and L2 stage: Students of different ages and stages of L2 learning used different
strategies, with certain strategies often employed by older or more advanced students
Learning style: Learning style (general approach to language learning) often determined
the choice of L2 learning strategies For example, analytic-style students preferredstrategies such as contrastive analysis, rule-learning, and dissecting words and phrases,while global students used strategies to find meaning (guessing, scanning, predicting) andto converse without knowing all the words (paraphrasing, gesturing)
Tolerance of ambiguity: Students who were more tolerant of ambiguity used
significantly different learning strategies in some instances than did students who were lesstolerant of ambiguity
2 Vocabulary and Vocabulary Learning Strategies
2.1 Definition of Vocabulary
Since we all know what the words mean, why spend time defining them? Every wordrefers to a concept, which exists in the memory of the listener's mind Some concepts arethe product of nonverbal experiences For instance, when we were very young, we sawseveral kinds of animals, which other people called dogs; this formed our concept of“dog” Since the particular animals we saw differed from those seen by other people, our
Trang 12concept is slightly different from the concepts that other people have On the other hand,certain concepts are the result of verbal or written explanations by other people Here theexplanations differed, so again our concept is not identical to that of other people Anyconcept that we have, therefore, consists of other, previously learned, concepts and theseconcepts differ from person to person So you see, no two people can have exactly thesame concept, as related to a given word
Thus, so far there have been different definitions of vocabulary Each linguist gives his
own definition According to Michael Lewis (1993:89), Vocabulary " may be individualwords, or full sentences - institutionalized utterances - that convey fixed social orpragmatic meaning within a given community” Peny Ur, in her book: “A course inlanguage teaching” defined vocabulary roughly "as the words we teach in the foreignlanguage However, a new item of vocabulary may be more than a single word: acompound of two or three words or multi-word idioms” (1996, p.60) Pyles and Algeo alsogive their idea about vocabulary They said “when most of us think about language wethink first about words It is true that the vocabulary is the focus of language It is inwords that we arrange together to make sentences, conversation and discourse of allkinds” (1970, p.96)
In short, vocabulary is an essential part of language, as Wilkins emphasized this with his
saying: "without grammar, very little can be conveyed, without vocabulary nothing can beconveyed” (cited in Hoang Tat Truong 1985:1).
2.2 Vocabulary Learning Strategies
In the literature on LLS, there is no official definition for VLS Because VLS areconsidered as one part of LLS which in turn are part of general learning strategies LLSencourage greater overall self-direction for learners Self-directed learners are independentlearners who are capable of assuming responsibility for their own learning and graduallygaining confidence, involvement and proficiency So is the case with VLS
Oxford (1990:8) gave the working definition of VLS as “ specific behavioural or mentalactions taken by learners to make their vocabulary learning easier, faster, more enjoyable,more self-directed, more effective, and more transferable to new situations”.
It is believed that the characteristics of learning strategies introduced by Oxford are alsotrue to VLS.
Trang 132.3 Classification of Vocabulary Learning Strategies
Word knowledge is an essential component of communicative competence, and it isimportant for both production and comprehension in a foreign language Knowing a wordinvolves knowing:
A great deal about its general frequency of use, syntactic and situational limitations onits use,
Its underlying form and the forms that can be derived from it, The network of its semantic features and,
The various meanings associated with the item.
Knowing a word is also defined as knowing its spelling, pronunciation, collocations (i.e.words it co-occurs with), and appropriateness Therefore, lexical competence is far morethan the ability to define a given number of words and covers a wide range of knowledgewhich in turn requires a variety of strategies to gain the knowledge Foreign languagelearners may then use various strategies to acquire the target language word knowledge.Taking this into consideration, second and foreign language researchers have made variousattempts to classify VLS employed by foreign and L2 learners In this thesis, we used theclassification of Oxford as the main theoretical background to study:

Table 1: Direct and Indirect learning strategies
(Adapted from Oxford 1990:18-20)
We can see the details of learning strategies from the above table In this study, we only
chose five specific strategies of CS to apply in the experiment including Formallypracticing with sounds and writing systems; Notes-taking; Analyzing expressions;
Trang 16Highlighting and Practicing naturalistically CS belong to the direct strategies As the
word “direct” conveys, these strategies are directly involved in learning the target
language Oxford defines CS as “enabling learners to understand and produce newlanguage by many different means” The first letters of these strategies sets create theacronym “PRAC” as a memory aid of the essence of these strategies “CS are PRACticalfor language learning” (Oxford, 1990:43)
3 Cognitive Strategies
3.1 Definition of Cognitive Strategies
It has long been recognized that the CS that students use when tackling learning task are a
major influence on the quality of the learning outcome As Paris stated “People rely on CSto promote learning, remembering and problem solving” (1998, p.299).
According to Kirby and Lavoson (1983), CS are beneficial to learning, they can beidentified and they can be developed Indeed, CS development has provided positiveresults to students of all ages and abilities (Mayo, 1993) regardless of material format andwhether strategies are used publicly or privately (Patterson, Dansereau and Newbern, 1992).Bouffard and Dunn (1993) claimed that when an appropriate CS is shown to pupils andthey are requested to use it, motor performance usually improves.
So far, many researchers have given the definitions of CS However, there are difficultiesin defining because there seem to be concerns for how general and incorporating the termshould be.
Some definitions argued that CS must be conscious, planned processes whilst otherdefinitions related to any activities that streamlined cognitive performance.
According to Perry and Murphy (1986), Lipson and Wixon (1983), CS signify thecollection of mental tactics selected, employed and controlled by an individual in aparticular learning situation to facilitate their acquisition of knowledge or skill, and toachieve their desired objectives It has been further claimed that CS can be defined asbeing deliberate, learner-initiated and learner-controlled (Palmer and Goetz, 1988) Thus, it
Trang 17is implied that CS will not be utilized unless a pupil is motivated and deliberately attemptsto initiate and control them.
Derry and Murphy (1986) supposed that CS may be viewed as a continuum fromgenerality to specificity, from cognitive style and the most generalized of CS to the mosttask-specific cognitive tactics.
To sum up, CS are very important to improve students’ ability Specially, these strategiesare crucial for academic skills.
3.2 Clarifying Oxford's Cognitive Strategies
Repeating: This strategy is most often employed by most students Students reador write or both read and write a new word over and over again.
Formally practicing with sounds and writing systems: Students practice sounds(pronunciation, intonation, etc) in a variety of ways but not yet in naturalisticcommunication practice Practicing the writing system of English is not a problemfor Vietnamese students because they use Roman scrip as English.
Recognizing and using formulas and patterns: Being aware of and/ or using routineformulas (single, unanalyzed units).
Recombining: Students combine known words in new ways to produce a longersequence For instance, they link one phrase with another in a whole sentence. Practicing naturalistically: Students practice using new words in natural realistic
settings, as in participating in a conversation, reading a book, writing diary, etc. Reasoning deductively: Students use general rules and apply them to specific
cases For example, students can use general rules of English affixes to guess themeaning of new English words or to facilitate their learning new words.
Analyzing expressions: students determine the meaning of a new expression bybreaking it down into parts and using the meanings of the parts to understand themeaning of the whole expression.
Trang 18 Analyzing contrastively: Students compare elements (sounds, vocabulary, etc) ofEnglish words with those of Vietnamese to determine the similarities anddifferences between them.
Translating: Students convert an English expression into Vietnamese (or the otherway round), using one language as the basis for understanding and producinganother.
Transferring: Students directly apply knowledge of words from one language toanother in order to understand or produce an expression in the new language. Taking notes: Students take notes of specific points about a word they want to
Highlighting: Students use many techniques (underlining, circling, color-coding,etc) to highlight the words they want to learn.
Trang 19CHAPTER 2: METHODOLOGY
1 Rationale for using Experimental method
As mentioned in the preceding chapter, the purpose of this study was to investigate theeffect of CS in learning vocabulary and discover students' attitudes towards the applicationof CS in learning vocabulary, therefore, the best method chosen for this study was theexperimental research The fact that this method offers the luxury that others cannot As
Hopkins & Antes (1990, p.307) said in the strictest sense "An experiment can take placeonly on a laboratory setting with the greatest possible control to study the effects ofmanipulation” And in the broadest sense "any interjection of something different into anatural setting could be considered an experiment” (cited in Vu Thi Thanh Nha, 2006,p.38-39).
An experimental research is an attempt by the researcher to maintain controlover all factors that may affect the result of an experiment In doing this, theresearcher attempts to determine or predict what may occur Experimentaldesign enables the researcher to test his hypothesis by reaching validconclusions about relationships between independent and dependent variables.It refers to the conceptual framework within which the experiment isconducted To put it in other words, an experiment method, when donecorrectly, can provide a tremendous amount of power and control over theunderstanding of the causal relationship between variables.
According to Nunan (1992), there are three types of experiments: pre-experiment, experiment and true-experiment They are different from one another in terms of thedegree to which they impose control over the variables being studied and the degree ofrandomness that enters into the design (Salkind, 2006, p.218).
quasi-Basing on the characteristics of different experiments in language research in combinationwith the present conditions in which the study would be carried out, we decided to choose
the quasi-experiment design A quasi-experimenter treats a given situation as an
Trang 20experiment even though it is not wholly by design The independent variable may not bemanipulated by the researcher, treatment and control groups may not be randomized ormatched The researcher is limited in what he or she can say conclusively Quasi-experimentation in educational research is widespread because not only are manyresearchers also teachers, but many subjects are also students.
Moreover, the quasi-experimental design has greater external validity (more like real worldconditions) and much more feasible given time and logistical constraints And since this design is less intrusive and disruptive than the true-experiment design, it is easier to gain access to the subject population and that easier to conduct such a research
In short, the quasi-experimental design is the most practical and feasible for the researcher,all above factors considered.
2 Participants
2.1 The students
In this study we chose the participants in the two classes in which there are 40 non-Englishmajor students at the age of 19-22 from NACEC, including 12 males and 28 females Theywere divided into 2 groups: experimental group and control group with 20 each Theseparticipants were not randomly assigned because of the time limitation, expense andaccessibility We know that it is not always feasible to carry out the study with all thestudents in the population individually Thus, we chose basing on the basis of clustersampling that is proved to be convenient, inexpensive and time-saving (Salkind, 2006, p 92).The forty students participating in this study are the first yearstudents Their English levelwas Elementary The most serious difficulties for them are the lack of self-learningmethod, LLS and motivation Most importantly, they emphasized the need for instructionson how to learn better and to clear away all these problems Before the experiment theyhad finished one term of English In the first term, the material they used was Lifelines-Elementary (from Unit 1 to Unit 7) which is an integrated course book intended to developfour basic language skills: listening, speaking, reading, writing and especially learningvocabulary according to topics (For example, food and drinks, daily activities, clothes, etc)
Trang 21The two groups that we chose in this study were arranged in accordance with their level ofEnglish based on the results of their placement test
To sum up, we tried to select two compatible groups for the experiment Twenty studentsin each group officially became the subjects of the research and all information about themwas gathered and analyzed in the next chapter Despite the fact that there might be someinevitable variables such as intelligence and characteristics which vary from person toperson, the differences between two groups were limited to minimum.
2.2 The teachers
The two instructors were the researcher herself and another teacher at NACEC They bothhave been teaching at NACEC for nearly five years Before the experiment period, theywere arranged to meet and discuss the methods, contents, outcomes and time allocation forthe experiment
3 Materials and Data Collection Instruments
3.1 Materials
Course book: The participants taking part in this study used Lifelines-Elementary as the
main course book This course book is divided into fourteen topic-based units presentingand practicing vocabulary and grammar, as well as developing the four language skills(Reading, Writing, Listening and Speaking) After every two units, there is an extension tocheck the learnt knowledge
The interesting feature of this course book is that Vocabulary is learnt according to topics.It means that there are 14 topics corresponding with 14 units:
- Unit 2: Classroom language- Unit 9: Verbs - Unit 3: Describing people - Unit 10: Travel
- Unit 5: Food and drinks- Unit 12: Parts of the body- Unit 6: Daily activities- Unit 13: Phrasal verbs
Trang 22- Unit 7: Parts of a house- Unit 14: The world
Because of the time limitation, the researcher only chose two units (Unit 11 and Unit 12)to do the experiment for this study Each unit was taught within nine periods.
Handouts: In the experiment group, handouts were designed by the researcher herself and
delivered to the students as student-training worksheets Each of the worksheets provided
the students what it meant by the term "Cognitive Strategies”.
Projector: This is a supplementary tool in teaching and learning which help teachers to
teach more successfully In this study, the researcher used activities on web-sites So,projector is really useful and create positive atmosphere and motivation in learningclassroom.
3.2 Data Collection Instruments
This study employed both quantitative and qualitative methods including pre-test (at thebeginning of the experiment), post-test (at the end of the experiment) and questionnaire tocollect data with the aims of investigating the effect of CS in learning vocabulary
3.2.1 Tests
In the researches and in language acquisition, tests are used to check students' vocabularyability and knowledge Thus, in order to know students' results exactly, teachers mustdesign good tests The question is: What is a good test? It should have five maincharacteristics: validity, reliability, discrimination, practicality and backwash.
To ensure those characteristics of the test, both pre-test and post-test in this study were
taken from Building skills for the TOEFL IBT Beginning by Adam Worcester - LarkBowereman - Eric Williamson and English pronunciation in use by Mark Hancock This is
because these two books are considered a standardized source So, they are widelyaccepted to be highly valid and reliable in measuring one's language proficiency
The pre-test and post-test used in this study were in fact two versions of the same test Theuse of the same test before and after the experiment treatment was to measure exactly thedifference that may have been caused by that treatment However, to minimize the possibleeffect of the test familiarity on the students' gains between the two test administrations,some items of the first version of the pre-test were reordered for the second use (post-test).
Trang 233.2.2 Questionnaire
Questionnaires are also the effective instrument for collecting data in this study According
to Brown (2000) “Questionnaires are any written instruments that present respondentswith a series of questions or statements to which they are to react either by writing outtheir answers of selecting from among existing answers” This makes questionnaire data
particularly suited for quantitative, statistical analysis With questionnaires, theexperimenter can employ categories, viewpoints and models that have been preciselydefined in advance then determine the relationship between these categories and to test theresearch hypotheses from numerical or directly quantifiable data However, the data fromquestionnaires are ideal because the participants can have some time to think about theanswers, which may reflect reliable facts.
The questionnaire in this study was used at the end of the experiment (post-programquestionnaire) This questionnaire aimed at investigating students' attitudes and commentstowards the application of CS in learning vocabulary The questionnaire took 15 minutes tocomplete It focused on three parts: (1) the students' opinions about the application of CSin learning vocabulary including 10 statements in which each statement students couldchoose one of the two cases: Y = Yes; N = No; (2) the students' preference towards fivespecific strategies (arranged in the order of the level of the students' preference); and (3)the students' ideas and suggestions to make the application of CS in learning vocabularymore enjoyable and useful in the next school year (five suggestions were given so thatstudents could choose Agree or Disagree) The information and results collected from thisquestionnaire were valuable As a result, the researcher had a reliable basis to decidewhether or not to go on applying CS in the future
3.3 Data collection procedures
The experiment was conducted for eight weeks During the experiment, the researcherherself directly taught the experimental group and another teacher taught the control group(under the researcher’s observation) In order to collect sufficient information about thestudents' VLS or techniques through the application of CS as well as their attitudes towardsthis, the researcher exploited a pre-test, a post-test and a questionnaire Here below is theprocedure of the study:
