Abstract
This study is composed of three experiments. The first one aims
to analyze the word frequency and the recycling rate of target
vocabulary in Japanese EFL textbooks. To do this, three different
level textbooks were analyzed by an instrument called Lextutor,
which shows quantitative data about vocabulary in a text. The
findings indicated that most content words were less frequent and
recycled than function words; the word frequency and the
recycling rate tend to be increased in textbook which has more
word tokens. The aims of the second and third experiment are to
find trends in vocabulary learning strategies (VLSs) among the
participants for different purposes: regular vocabulary learning
and vocabulary test. One hundred and seventy one freshmen in a
high school participated in these experiments. In the second
experiment, the researcher provided them the questionnaire to
explore their VLS use for regular vocabulary learning. The
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 3
results revealed that majority of the participants depended on
the ‘written repetition’ strategy; also, motivated students
tended to use meta cognitive strategies more than less motivated
students. Moreover, the third experiment revealed that the
participants used various types of ‘written repetition’ strategy
for short term retention.
Key words: word frequency, recycling rate, vocabulary learning
strategy (VLS)
Introduction
English as a foreign language (EFL) leaners need to learn
large numbers of vocabulary in order to read, write, speak, or
listen to English. Given that their vocabulary is limited, they
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 4
face a lot of difficulties in English communication. Although
other linguistic aspects involving phonetics, phonology, or
syntax are essential as well, nothing may be more important than
learning English words to establish successful communication. So,
it is not surprising that “this area of language learning has
received significant attention” (Oxford, 2011, p. 254) and
“specialists now emphasize the need for a systematic and
principled approach to vocabulary by both the teacher and the
learner” (Decarrico, 2006, p. 285). As many researchers insist,
success in second language (L2) learning depends on acquiring as
many English words as possible.
However, when it comes to an EFL setting like Japan, most
learners receive less exposure to English outside classroom,
compared to learners learning English as a second language (ESL).
That is, ESL learners have to learn English to survive in the
society where English has some kind of special status (Crystal,
2002), while Japanese EFL learners do not need to use English in
their monolingual society, Japan. Furthermore, it is not unusual
that less motivated students do not open their English textbooks
at home without being forced to do so; even motivated students
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 5
would not be able to make up for the lack of input by their own
efforts. In such a challenging environment for English learning,
“the principal and sometimes the only source of foreign language
vocabulary will be from the language they are exposed to in the
classroom; the textbooks and teacher’s language” (Milton, 2006,
p.193). In sum, English teachers are highly responsible for
students’ vocabulary learning, so they need to explore more
effective teaching methods for vocabulary acquisition.
As the first step towards effective vocabulary teaching, it
is necessary for teachers to analyze the textbook that they use.
More specifically, they should explore what kinds of word are
frequently used and whether the target words are appropriately
recycled throughout the textbook since these factors are crucial
for vocabulary acquisition. According to the new course of study
(2009) published by the Ministry of Education, Culture, Sports,
Science, and Technology (MEXT), the number of target vocabulary
items, which students learn for six years from junior high
through senior high school, will be increased; the maximum number
will be the 3,000 most frequent word families. This revision
should be welcome because students will be exposed to more words
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 6
than what they are now. However, it is still uncertain about
whether the target words are sufficiently recycled throughout the
textbook or not; some words which are treated as the target words
in a chapter may appear only a few times, and in the worst case,
they may never come out in the other chapters.
Besides, teachers need to know what kind of strategy
students usually use to learn English vocabulary. In fact, each
student may employ different vocabulary learning strategies
(VLSs) in various situations; some students may consult a
dictionary to check a meaning or a syntactic feature of the
target word, while others may just jot down or utter the word
over and over again. Although it is basically better to respect
the strategies that each student employs (Nyikos & Fan, 2006),
teachers have to lead them in the right direction if they use an
ineffective VLS. Indeed, some students may adopt unreasonable
VLSs which do not suit their learning purposes. For instance,
Kadota and Ikemura (2006) pointed out that less advanced students
tended to highly depend on the ‘written repetition strategy’ to
memorize English vocabulary, without exploring more effective
VLSs; they may just employ the same strategies as what they do to
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 7
memorize Japanese ‘kanji’. Autonomy is a key factor to make
language learning successful, but their efforts would be
meaningless if they are not suitable for the learning purpose.
From these perspectives, the current study addresses the
following research questions:
1. What kinds of word are frequently used in the Japanese EFL
textbooks?
2. Is there enough recycling in the Japanese EFL textbooks to
support incremental learning?
3. What kind of VLS do Japanese high school students adopt for
regular vocabulary learning and vocabulary test?
Literature review
Vocabulary in textbooks
In general, it has been said that EFL learners need to
acquire the most frequent 2,000 words in English based on A
General Service List of English Words (West, 1953), which enable them to
recognize about 80 percent of any normal text (Milton, 2006;
Nation, 2001; Schmitt, 2000). Furthermore, Nation (2006)
calculated that between 2000 word and 3000 word families covered
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 8
about 95 percent coverage, and Schmitt (2010) insisted that
learners needed to know between 6,000 and 7,000 words to gain 98
percent comprehension in an authentic text. Taking account of the
actual situations, acquiring between the frequent 2,000 and 3,000
word families would be a realistic goal for Japanese high school
students.
Of course, it is essential for them to make numerous efforts
in order to acquire 2,000 -3,000 word families. In particular, as
Schmitt (2010) pointed out, “both learning and forgetting would
occur until the word is mastered and fixed in memory” (p.23),
they need to overcome possible ‘forgetting’ during the course of
learning. In fact, Nagy (1997) revealed that the chances of
learning and retaining a word from one exposure when reading were
only about 5 percent to 14 percent. In order to overcome such a
difficulty and reinforce long-term retention of learning words,
nobody would doubt that ‘recycling’ is a powerful way. Thus,
teachers should keep sufficient opportunities for students to
recycle the words with regular intervals (Schmitt, 2000), and
hopefully, textbooks offer sufficient recycling opportunities so
that students can be exposed to the target words repeatedly.
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 9
Indeed, Milton (2006) insisted that an effective textbook was
probably going to introduce large quantities of vocabulary at
regular intervals. Certainly, such textbooks would enable the
learners to learn the target words effectively. However, it may
be difficult to organize such an ideal textbook for vocabulary
learning. As Schmitt (2010) argued, general textbooks or adult
authentic texts seem to have less repetition, compared with
children’s reading books or Graded readers; also, Nation (1993)
claimed that it would be impossible to recycle every item
systematically in a course book.
Although there are pros and cons, such analysis may not be
applied to textbooks for Japanese EFL learners since these claims
are generally based on ESL textbooks published in the UK and the
US. In terms of text analysis, some Japanese researchers have
conducted the studies from the various angles, such as word
tokens and word frequency (Nakajo et. al, 2007), genre and text-
type (Sakai & Wada, 2012), or relationship between vocabulary of
textbook and entrance examination (Matsuo, 2000), but they did
not deal with the recycling rate of the target words in Japanese
EFL textbooks. Therefore, it is worth exploring this issue in
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 10
order to draw a clearer picture of an effective textbook for
vocabulary learning in Japanese setting.
Language learning strategies
Language learning strategies are defined as “specific
actions, behaviors, steps, or techniques used by students to
enhance their own learning” (Scarcella & Oxford, 1992, p. 63).
Besides, Oxford (2006) claimed, “when the learner consciously
chooses strategies that fit his or her learning style and the L2
task at hand, these strategies become a useful toolkit for
active, conscious, and purposeful self-regulation of learning”
(p. 359). Since students are generally required to manage their
own learning outside the classroom, it is better for them to be
familiar with various strategies which are suitable for the
learning needs. Indeed, as Cohen and Macaro (2007) introduced in
Language Learner Strategies, researchers around the world have studied
and presented varieties of strategies in reading, writing,
speaking, listening, or grammar, as well as vocabulary learning
strategies (VLS).
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 11
For English teachers in Japan, the most informative VLS
studies would be the one conducted by Schmitt (1997). In order to
find general VLS use among Japanese EFL learners, he carried out
surveys of a broad cross-section of Japanese learners: Junior
high school students, high school students, university students,
and adult learners. The results indicated that Japanese EFL
learners, especially young learners, tended to depend highly on
the ‘written repetition’ and ‘verbal repetition’ strategies to
consolidate words although “the patterns of strategy use can
change over time as a learner either matures or become more
proficient in the target language” (p. 223). This result, he
pointed out, “can, at least partially, be attributed to the study
style encouraged by the Japanese school system; students are
required to memorize English grammar and vocabulary, usually
through repetition” (p.220). In addition, in Japanese education,
students are generally instructed to write Kanji over and over
again to be familiar with its script. That is, young learners may
just follow this habit to memorize English words without
exploring other strategies.
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 12
In order to ‘acquire’ vocabulary, learners must learn
various factors including multiple word meanings, connotations,
derived forms, spellings, pronunciations, proper grammatical
uses, or collocation and so on (Nation, 1990). That is, they need
to employ suitable VLSs, depending on learning purposes. However,
it is no wonder that some learners, especially novice learners,
may adopt unreasonable VLS without any suggestions. So, it is
important for teachers to realize what kind of VLS students use
for various purposes such as regular vocabulary learning or
vocabulary test. Although Schmitt (1997)’s study revealed
informative findings about VLS use among Japanese learners, it
did not refer to VLS use for a specific purpose like vocabulary
test. Thus, it is meaningful to explore the topic as well as that
of regular vocabulary learning.
Experiment 1: Text analysis
For most Japanese high school students, the textbook is
their main tool of vocabulary learning. In other words, their
success of English learning depends on whether they can
appropriately acquire the words in textbook or not. However, it
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 13
is supposed that many students may not be able to learn
vocabulary effectively without any instructions. So, it is
important for teachers to analyze the textbook they use in order
to make effective teaching plans and provide useful instructions
with students; specifically, the word frequency and the recycling
rate of the target words, which are essential factors to
vocabulary acquisition, should be explored. This experiment was
designed from these perspectives.
Instruments
Three textbooks, which are published in Japan for the
beginning level (All Aboard), the intermediate level (Power on), and
the advanced level (Provision) first grade senior high school
students, were analyzed by an instrument called Compleat Lexical
Tutr / Lextutor V6.2 (http://www.lextutor.ca/freq/eng/). As Schmitt
(2010, p. 341) said, “Lextutor is the most essential tool in the
vocabulary researcher’s toolbox”, this tool shows a lot of useful
data about vocabulary such as the word frequency, the recycling
index, or word tokens in a text; furthermore, it calculates the
percentage of the high frequency 2,000 word families, Academic
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 14
Word List (AWL), and off-list words in a text. This high-frequency
2,000 word families list is based on A General Service List of English
Words (West, 1953) and “the resulting of AWL contains 570 word
families which covers 10% of the academic corpus” (Schmitt,
p.79).
Procedure
In order to explore the word frequency in the textbooks, the
researcher used the Web Frequency Indexer V1.3, which caliculates the
word freguency from user texts and downloads influential
frequency lists. First, all the chapeters in each textbook were
scanned and pasted into the tool box (see Figure 1.1). Then,
Frequency Indexer calculated the word frequency in the textbook and
provided the frequency list (see Figure 1.2). Following this
procedure, the researcher gained the frequency lists of All
aboard, Power on, and Provision.

Lextutor has another useful function called Vocab Profile, which
generates data about the percentage of the high frequency 2,000
word families, Academic Word List (AWL), off-list words, and the
number of word tokens in a textbook. In order to gain a
vocabulary profile, the researcher scanned all chapters in a
text, and pasted them into the tool box (see Figure 1.3).
Following these steps, the researcher collected the data from all
textbooks (see Figure 1.4).

Figure 1.4. The results of the vocabulary profile in a textbook
In order to explore the recycling index of a textbook, all
chapters were divided into two sections, chapter 1-5 and chapter
6-11. Then, the researcher scanned each section and pasted them
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 17
into the tool boxes respectively (see Figure 1.5). Text Lex Compare
indicated the word families which were ‘unique’ to one section
and ‘shared’ in two sections (see Figure 1.5). That is, if a word
is shown in the ‘shared’ box, it means that the word is recycled
in two sections; on the other hand, a word in the ‘unique to
first / second’ box appears in only one section. Following this
procedure, the researcher explored words which were recycled in
two sections.

In each procedure, proper nouns like names of specific people or
place were excluded from the results.

Word frequency
Table 1.1 shows the ten most frequent words in Provision,
Power on, and All aboard, and indicates that ‘function words’
dominate in the top frequency of all textbooks. This may be a
matter of course because “it is probably impossible to avoid
repeating much functional vocabulary, which is essential to well-
constructed language” (Milton, 2006, p.209). According to Schmitt
(2010), the first 50 words in the list of the 2,000 most frequent
words are made up entirely of function word.

By contrast, it seems that frequent content words are likely
to be different depending on textbooks (see Table 1.2) although
the high-frequency words, like ‘people’ and ‘number’ frequently
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 20
appear in all the texts. Another finding is that most content
words in the list are involved in A General Service List of English Words
(West, 1953). Since the high-frequency 2,000 words cover more
than 80 percent of running words in English text (Nation, 2001),
it may be not surprising that these basic words frequently appear
in the textbooks.

Note. Proper nouns are not involved in the list.
Indeed, the high-frequency 2,000 words are appropriately
distributed in all the textbooks; the percentage of 2,000 most
frequent words in Provision is 91.5 %, Power on is 88.56 %, and All
aboard is 88.38 % (see Table 1.3). Incidentally, Schmitt (2010,
pp.70-71) showed that the percentage of the 2,000 high-frequency
words in the beginning level Graded reader was 87.68 %.
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 22
Additionally, the result indicates that the number of the word
tokens is highly correlated to the ratio of the 2,000 high-
frequency word families in a textbook (r = .97). In sum, the more
words are involved in a text, the more often students encounter
high-frequency words.

Note. Graded reader (Schmitt, 2010, p.71).
When it comes to the number of exposures which is necessary
to promote incidental learning from reading, the previous
researches revealed some concrete results. For instance, Pigada
and Schmitt (2006) found that there was a discernible rise in the
learning rate by about 10 exposures; Horst et al. (1998) also
revealed that it was likely for learners to learn words appearing
8 or more times throughout the text. Of course, these numbers
would depend on the proficiency level of the learners, but as a
benchmark of incidental learning, Schmitt (2010) insisted, “8-10
reading exposure may give learners a reasonable chance of
acquiring an initial receptive knowledge of words” (p.31).
Following his claim, the researcher counted the number of the
content words appearing more than 8 times in a text book (see
Table 1.4). The result indicates that there is a strong
correlation between the number of content words which appear more
than 8 times and word tokens in a textbook (r = .98). Again,
learners are more likely to encounter the high-frequency words in
a textbook which has more word tokens.

Word recycling
Besides the word frequency, it is necessary to explore
whether the target words are used in only one section or recycled
in more than one section because recycling is crucial to avoid
possible forgetting. Indeed, Schmitt (2010, p.23) pointed out,
“forgetting can occur even if vocabulary is relatively well
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 25
known, such as when one does not use a second language for a long
time, or one stops a course of language study”.
Table 2.1 shows that high-frequency content words such as
‘people’, ‘number’, ‘like’, or ‘go’ are sufficiently recycled and
most content words recycled in the textbooks are ranked in the
2,000 high-frequency word list. On the other hands, low-frequency
words like ‘toad’ and ‘frog’ seem to be intensively used only in
one chapter and they do not appear at all in other chapters.
Perhaps, this may be because a frog is the main character of the
chapter in which the words ‘toad’ and ‘frog’ frequently appear;
likewise, the words ‘hippos’ and ‘substance’ are repeatedly used
in the chapter, Hippos’ secret substance, in order to describe the
unique features that hippos have. That is, law frequency words
may be more likely to be influenced by a thematic content,
compared with high-frequency words.

Although some high-frequency words involving function words
seem to be sufficiently recycled throughout a textbook, it cannot
be said that overall recycling rate is enough in all the
textbooks. Indeed, the recycling rate in each text book is less
than 50 percent (see Table 2.2). This rate absolutely decreases
if the function words are not counted. Table 2.3 shows that the
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 28
number of the content words is about one-thirds of all in the top
fifty repeated word families list. That is, most content words
are not recycled in all the textbooks.

Discussion of experiment 1
The results of the experiment indicated that function words
were frequently used in the textbooks compared with content
words. Considering the components of English sentences, this
result is not surprising because function words are essential for
organizing a sentence in almost all cases. Indeed, some studies
exploring the word frequency revealed that the function words
dominated the frequency list (MacCathy & Carter, 1997; Leech,
Rayson, & Wilson, 2001). Also, the researcher found that less
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 30
frequent words which did not rank in the list of 2,000 word
family were likely to be affected by a thematic topic. Although
the frequent 2,000 word family was distributed in the textbook
sufficiently, when it comes to the recycling rate of target words
in the textbooks, most content words were less recycled in the
textbooks, except for some high-frequency words such as ‘people’,
‘world’, ‘life’ or ‘go’. It is assumed that the ratio of
recycling would vary depending on texts, but the finding supports
the claims that general textbooks or adult authentic texts have
less repetition unlike children’s reading books or Graded readers
(Schmitt, 2010) and that it would be impossible to recycle every
item systematically in a course book (Nation, 1993). Thus, it is
necessary to consider what to overcome the difficulty.
Furthermore, as Milton (2006) claimed that “the more
vocabulary that is presented in a course book, the more
vocabulary learners seems to acquire” (p.207), the results of the
experiment show that textbooks which have more word tokens are
likely to increase the word frequency and the recycling rate of
the target words, which are essential factors for vocabulary
acquisition (see Table 1.3 & Table 1.4). Although it is necessary
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 31
to provide additional trainings in order to develop ‘productive
knowledge’, when it comes to developing ‘receptive knowledge’
through reading a textbook, 8-10 reading exposures would be a
benchmark to promote incidental learning (of course, this would
be different depending on proficiency levels or the difficulty of
words). So, if a textbook does not provide sufficient
repetitions, teachers have to make up for the deficiency by using
the target words repeatedly in teacher talk, organizing tasks in
which students are unconsciously exposed to the target words, or
providing regular vocabulary tests and so on.
The good news is that all the text books adequately contain
the 2,000 high frequency word families (see Table 1.3). Although
Milton (2006, p.204) hypothesized, “an effective textbook is
probably going to introduce frequent and infrequent vocabulary in
roughly equal amounts”, it is more effective to address high
frequency words at the beginning and intermediate level. In
short, novice learners should focus on acquiring the 2,000
frequent word families which enable them to achieve basic
communication in English; as they mature, they should begin
exploring beyond the 3,000 word families level. Since textbooks
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 32
seem to offer sufficient high-frequency words, it is important
for teachers and students to use the resources appropriately.
Experiment 2: Learning strategy for vocabulary learning
In general, most teachers expect students to memorize the
target words before sitting in the class and to exert individual
effort to retain these words outside the classroom. Indeed, the
four skills, listening, speaking, writing, and reading, are
preferentially addressed in the lesson, so it is difficult to
secure enough time for vocabulary instruction within limited
time. Thus, in many cases, students are required to manage their
own vocabulary learning by themselves. So, it is important for
them to know effective vocabulary learning strategies (VLSs)
which facilitate vocabulary learning. If they adopt an
ineffective strategy which does not apply to a learning purpose,
teachers have to lead them in the right direction. Thus, it is
crucial to know how students learn vocabulary. From this
perspective, the following experiment was designed to explore the
tendencies of VLS use among Japanese high school students.

ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 33
The participants involved in the experiment were 171
freshmen in a senior high school in Akita prefecture, Japan.
Since this high school offers a variety of majors, such as
special advanced learning courses, general courses, agricultural
courses, and environmental courses, students’ proficiency levels
are diverse. So, 30 students who belong to the special advanced
course and 141 students in the general courses were asked to
participate in the study.
Furthermore, for English lessons, students in the general course
which consisted of four homerooms were divided into three levels
depending on the result of their entrance examinations; 56
students were in the two advanced classes (29 students and 27
students), 53 students were in the two intermediate classes (25
students and 28 students), and 32 students were in the two
beginning classes (16 students and 16 students).
Taking account of these situations, in this experiment, 86
students (30 students in the special advanced learning course and
56 students in the advanced classes) were categorized as the
‘advanced group’, while 85 participants (53 students in the
intermediate classes and 32 students in the beginning level
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 34
classes) were the ‘less advanced group’. Then, the researcher
compared the trends of VLS use of the two groups.
Instruments
In order to ascertain the participants’ learning habit, a
questionnaire composed of 27 questions was administered in
Japanese (see Appendix 1); it was based upon the questionnaire
made by Schmidt et al (1996) and was modified to suit the purpose
of the study. The first 10 items concerned learning motivation;
the next 6 items concerned learning anxiety; and the final 11
items concerned VLS. Each statement had a four-point scale
(Likert scale) ranging from ‘1’ indicating ‘I totally disagree’,
to ‘4’ ‘I totally agree’.
In terms of the VLS section, the participants who marked ‘3’
or ‘4’ were counted as the ‘users’ of the strategy, while those
who answered ‘1’ or ‘2’ were counted as the ‘non users’; then,
the percentage of the ‘users’ was calculated. Also, each VLS was
divided into three categories, ‘cognitive strategy’, ‘meta
cognitive strategy’, and ‘social strategy’ in order to clarify
the participants’ VLS use depending on different purposes; in
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 35
terms of the concepts of these strategies, the researcher
referred to Language learning strategies (Oxford, 1990). In order to
get a clearer picture of VLS use among Japanese senior high
school students, the results of the cognitive strategy and the
social strategy section were compared with those of Schmitt
(1997) which examined VLS use of Japanese high school students.
Unfortunately, in terms of meta cognitive strategy, the
researcher could not find the relevant data in Schmitt’s study,
so comparison was not conducted.
Procedure
The survey was carried out soon after the participants were
enrolled in the school. Since they were divided into some classes
as referred in the previous paragraph, each teacher who took
charge of a class conducted the questionnaire in the same day. In
order to avoid a bias for the experiment, the teachers informed
the participants that the information would be used for only the
research aim and it would not affect their grade. The
participants were required to write students ID number on the
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 36
questionnaire sheet and respond to the questions in a span of ten
minutes.
Results
1. Meta cognitive strategies

Oxford (1990) insisted, “meta cognitive strategies provide a
way for learners to coordinate their own learning process”
(p.136) so it is necessary for learners to be familiar with the
strategies since teachers cannot support students outside the
classroom. Then, she defined ‘centering your learning’,
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 37
‘arranging and planning your learning’, and ‘evaluating your
learning’ as the core concepts of meta cognitive strategy (see
Figure 2.1).

compared with the students in the less advanced group (preview:

from the result of the questionnaire indicating that the mean of
learning motivation in the advanced group is higher than that of
the less advanced group (see Table 3.2).

As many experts have emphasized the relationship between
motivation and strategy use (Cohen & Macaro, 2007; Nation, 2001;
Oxford, 1990, 2011; Schmidt et. al, 1996), it would be assumed
that the more motivated learner is, the more likely to use ‘meta
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 40
cognitive strategy’ to regulate themselves. That is, many
motivated learners may positively manage their own learning
outside the classroom, while many less motivated learners may
give up making further efforts. Such attitudes would affect their
developments of language learning.
2. Cognitive strategies
Figure 2.2 The diagram of the cognitive strategies (Oxford, 1990, p. 69)
Figure 2.2 illustrates the diagram of cognitive strategies;
they are divided into four sets including ‘practicing’,
‘receiving and sending messages’, ‘analyzing and reasoning’, and
‘creating structure for input and output’. As Oxford (1990)
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 41
claimed, cognitive strategies, which range from repeating to
analyzing expressions to summarizing, would be essential in
learning a new language. Indeed, cognitive maturity is a key to
success in second language (L2) learning, especially for learners
who start learning L2 after acquiring their mother tongue
(Lightbown & Spada, 2006). That is, since most L2 learners need
to make conscious efforts to acquire L2, they should be familiar
with cognitive strategy.

Note. Cog: cognitive strategy, Scmitt: the result of the survey
conducted by Schmitt (1997).
The results of ‘cognitive strategies’ users (see Table 3.3)
are interesting enough to consider the relationship between
strategy use and proficiency levels. As for this point, Schmitt
(1997) claimed that many of the ‘deeper processing strategies’
were perceived as being more helpful as learners mature,
paralleling their increased use. For example, sufficient
grammatical knowledge and reading proficiency would be needed to
learn words in a textual context; it is necessary for learners to
understand various factors, such as knowledge of morphology,
syntax, or discourse, in order to discover the meaning of the
words in a sentence. That is, additional abilities besides
memorizing skills are required to adopt a deeper processing
strategy like the ‘learn words in textual contexts’ strategy.
Therefore, it is no wonder that the percentage of the users of
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 43
this strategy among the less advanced group (35.7%) is lower than
that of the advanced group (60 %).
Whereas, the percentage of the ‘written repetition’ users is
definitely high in both the advanced group (90%) and the less
advanced group (82%). This result is almost the same as that of
Schmitt’s study, which indicated that 89 percent of high school
students supported this strategy. On the other hand, the
proportion of the ‘flash card’ strategy users is low in both the
advanced group (21.8 %) and the less advanced group (11.7%);
interestingly, Schmitt (1997, p.223) showed that the ratio of
this strategy users decreased as learners matured (high school:
29%, university: 12%, adult: 10%).
Unsurprisingly, the most popular cognitive strategy among the
participants is ‘consulting a bilingual dictionary’ (the
advanced: 97%, the less advanced: 80%); compared with Schmitt’s
result (73%), the ratio of the strategy users is high. Although
the result indicates that majority of the participants use a
dictionary to discover the meanings of a word, it cannot be said
that all of them can use it appropriately. As Miller and Glidea
(1985) pointed out, dictionary use is a complex work, so it is
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 44
necessary to instruct how to use it, especially for young
learners.
3. Social strategies
Figure 2.3 The diagram of the cognitive strategies (Oxford, 1990, p. 145)
Figure 2.3 indicates the diagram of social strategies. In
terms of this strategy, Oxford (1990) claimed that cooperation
with other people was essential in language learning because
language in all its aspects was a social act. This cooperation
requires the learner to interact well with both peers and more
proficient language users.

3. (Soc / Dis) Ask classmates for meaning 71
78 73
Note. Soc: Social strategy.
As for the ‘social strategies’, many participants of both
groups seem to ask the meaning of target words to classmates (the
advanced group: 71%, the less advanced group: 78%) rather than
teacher (the advanced: 40.9%, the less advanced: 38.1%). This
result is also close to Schmitt’s study which showed that 37
percent of the high school students depended on teacher, while 73
percent relied on classmates to discover the meaning of words.
However, according to Schmitt (1997), the percentage of the
learners who ask teachers for the meaning increases as they
mature. That is, there is a possibility that young learners may
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 46
just hesitate to ask teacher and depend on classmates, which is
easier and less strained. However, when it comes to effective
vocabulary learning, it is no wonder that learners should depend
on proficient learners or teachers who have deeper and wider
knowledge. In order to make such learning environment, it would
be important to establish a good rapport between the teacher and
students.
Discussion of experiment 2
The results of the experiment indicated that the
participants’ proficiency levels affected their VLS use to some
extent, especially in terms of the strategies which require ‘deep
processing’. Also, not surprisingly, motivated students tended to
make more efforts outside the classroom compared with the less
motivated students. As for these points, many researchers
reported that the use of learning strategies seems to be
demonstrably related to student’s learning motivation and
proficiency (Ahmed, 1989; Fan, 2003; Gu & Johnson, 1996;
Hosenfeld, 1977; Sanaoui, 1995). If they have successful
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 47
experiences and gain a sense of achievement during the course of
learning, it is no wonder that their self-efficacy and learning
motivation are generated; then, they would be positive to explore
more effective learning strategies to gain further success. It is
assumed that success of learning may depend on whether the
learner can establish such positive cycles or not. As many
researchers claimed, it is definitely important to generate
learning motivation.
Moreover, the experiment revealed that many participants
were the users of ‘simple repetition’ strategies like ‘written
repetition’ and ‘verbal repetition’. As referred to in the
previous study (Schmitt, 1997), the study style encouraged by
Japanese schools may have affected the result. In fact, Japanese
EFL students are encouraged to learn the script of ‘Kanji’s,
jotting down them over and over again; also, they are required to
memorize English grammar and vocabulary, usually through
repetition. Actually, these simple repetition strategies may be
easier for Japanese learners to adopt, compared with complex
strategies like ‘image word meanings’ strategy or ‘analyze word
parts’ strategy. In addition, they may not be positive to make
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 48
‘flash cards’ or ‘word lists’ because making cards or word lists
are time-consuming works. Although the strategy use are likely to
change as learners mature (Schmitt, 1997), it seems that the
participants depended on the user-friendly strategy, ‘simple
repetition’.
However, as Oxford (1990) suggested in her book, Language
learning strategies, learners may have used various kinds of
strategies in order to discover or consolidate the target words.
From this point of view, the VLSs referred in the experiment may
have been insufficient to make strong claims about the general
VLS use among Japanese high school students. In addition, if the
researcher had required the participants to report the process of
memorizing words or conducted an interview with them, it would
have been possible to draw the clearer picture of their strategy
use. But, during the process of making the questionnaire, the
researcher focused on the VLSs that seemed to be standard among
Japanese high school students, rather than involving complicated
strategy such as the ‘keyword method’ or the ‘image word’s
meaning strategy’. Also, the result of the experiment was almost
similar to that of Schmitt (1997), which is known as the most
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 49
informative study for VLS use among Japanese EFL learners.
Although the experiment may be sill insufficient, the results
revealed useful data for vocabulary instruction.
Experiment 3: Learning strategies for vocabulary test
In many Japanese high schools, vocabulary tests are
regularly conducted as a mile stone of vocabulary learning for
students. For most students, success on such a test would be an
important factor in generating their learning motivation. Indeed,
many participants answered in the questionnaire (see Table 3.2),
“I want to get a good score in a term exam” (mean of the advanced
group: 3.37, the less advanced group: 3.25). That is, even the
results of a weekly vocabulary test may affect their learning
motivation. If so, it is important for them to employ better
lerning strategies to gain good result in vocabulary test.
Although it is no wonder that regular vocabulary learning is
crucial (this theme was explored in the Experiment 2), it is also
important for teachers to know how strudents learn words to
prepare for vocabulary test which could be a powerful motivator
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 50
for language learning. From this perspective, the experiement was
designed.
Participants
One hundred and seventy one students who joined in the
experiment 2 participated in this experiment. They were divided
into the same two groups in the previous experiment (see p.20);
85 students were in the advanced group, while 86 students were in
the less advanced group.
Instrument
Vocabulary tests (see Appendix 2.1 & 2.2) examined spelling,
meaning, and syntactic features of the target words; the first
test was carried out three weeks after lesson 1 completed, while
the second test was administered just after lesson 2 was over.
Eight target words, which are ranked in the 2,000 most frequent
words of English, were picked up from each lesson. The researcher
made the tests. Additionally, blank sheets were distributed to
the participants so that they could practice the target words
before the test; the written records revealed their VLS use to
retain words in a short term.
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 51
Procedures
The vocabulary tests were conducted in each class. As it was
done in experiment 2, the teacher who was in charge of each class
administered the tests. Before each test, the teachers informed
the participants that the result of the test did not affect their
grades. Then, the target words were announced and they were
required to memorize these words, using the blank sheet which was
distributed by the teacher; the ‘practice time’ was for ten
minutes. After that, the sheets were collected, and the first
question sheets examining ‘spelling’ of the target words were
distributed to them (see Appendix 2.1). Three minutes later, the
sheets were collected and the second question sheets which asked
‘meaning’ and ‘syntactic feature’ of the target words were
distributed (see Appendix 2.2). The participants were required to
write their student ID number on both the blank sheet and the
question sheets. The testing time was seven minutes.

ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 53
Figure 3.2 AABBCC ABC type and Sentence type
Over 90 percent of the participants used the ‘written
repetition’ strategy to retain the words in a short span although
various styles could be seen. For instance, some participants
jotted down the target words just in order repeatedly (see Figure
3.1); this strategy was named as ABCABC type. About half
participants repeated a word several times until they firmly
memorized it, then moved to another word (see Figure 3.1); this
was named as AABBCC type. Another type of written repetition was
the one which mixed AABBCC type with ABCABC type; this was named as
AABBCC, ABC type (see Figure 3.2). Only a few participants tried to
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 54
make sentences using the target words, which was named Sentence
type (see Figure 3.2).
The most popular style among both groups seemed to be AABBCC
type although the percentage of the users varied in each test
(see Table 4); interestingly, some users repeated each word
equally, while others seemed to selectively pay attentions on
less memorable words. However, when it comes to the concept of
‘deep processing’ and ‘spaced repetition’, which were recommended
by many scholars as a reasonable way to memorize words (Craik &
Lockhart, 1972; Nation, 2001; Schmitt, 2000), AABBCC, ABC type
would be a good strategy because it has two ways with a spaced
interval rather than a monotonous way. But actually, the
percentage of the users of this strategy was lower than AABBCC
type. Also, it is assumed that the Sentence type strategy would be
the best way from ‘deep processing’ perspective. However, in
order to adopt this strategy, learners need to be sufficiently
proficient to make original sentences, using the target words. In
fact, few participants adopted this strategy in the condition
that they were not allowed to use other sources like a text book
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 55
or a dictionary. Given that they had been allowed to use them,
the number of the users may have increased.

Discussion of experiment 3
Since the aim of this experiment was to realize how the
participants learned vocabulary in a short term, the researchers
did not explore the correlation between the strategy use and the
scores of the tests (this will be the further question). Besides,
within the limited sources, it was hard to draw a clear picture
of their strategy use. Although majority of the participants used
the written repetition strategy, they may have adopted another
strategy if they were given a different kind of test. Also, they
may have used, in the experiment, another strategy like verbal
repetition with written repetition strategy. In order to picture
their strategy use more clearly, additional instruments like an
interview or self-report should have been conducted besides the
instrument.
However, it was meaningful to realize that the participants
used different kinds of written repetition strategies for a short
term memorization. This finding indicates that the participants’
learning style may affect the type of repetition. For instance,
some learners used AABBCC ABC type which requires multiple
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 57
processing; after completing repetition, they checked all words
again. On the other hand, others adopted monotonous way like
ABCABC type or AABBCC type; they just wrote down words over and
over again until memorizing them. When it comes to the concept of
‘deep processing’, which is said to be a powerful way to memorize
words, multiple processing like AABBCC ABC type may be
reasonable. But it would be safe to respect each student’s style
rather than forcing them to change their ways since learning
style “characterizes a general or dominant pattern” (Brown, 2007,
p.119), However, it is necessary to suggest alternative ways if
students cannot gain a good result.
Additionally, motivation for the tests may have been related
to their strategy use. Even though the same strategy was
employed, the number of repetition was different depending on the
participants. Indeed, some participants repeated the words only a
few times, while others did it more than ten times. Also, it is
no wonder that participants’ emotional state would be different
depending on each test; some participants who tried hard to
memorize words in one test showed the different performance in
the other test. Otherwise, their performance may have been
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 58
related to their personality or the outer factors such as the
time of day may have affected their attitude toward vocabulary
tests. So, it may be effective to check their emotional states
before each experiment in order to realize more precise analysis
of their VLS use (this will a further question). Since various
emotional aspects are likely to affect learning, it is important
for teachers to be sensitive to students’ performance and
encourage them if they seem to be less energetic toward learning.
General discussion
Figure 4. Typical pattern of forgetting and expanded interval
(Schmitt, 2000, p.130)
Judging from the recycling rate and word frequency of the
textbooks, it is obvious that teachers should consider the
appropriate ways to avoid forgetting vocabulary since this
generally occurs on all learners; then, the concept of ‘expanding
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 59
rehearsal’ (Schmitt, 2000, p. 130) would be the key to this
matter (see Figure 4). As one of the practical ways, it would be
reasonable to provide a mini vocabulary quiz regularly. Then,
each quiz should focus on a specific feature, such as phonetics,
syntax, semantic, or spelling of the target words; Japanese-English
Parallel Corpus (http://www.manythings.org/corpus/) is useful to
make various questions, using the same words. The point is to
have students repeatedly learn the same words from various
angles. Since “a large number of lexical characteristics affect
the way vocabulary is acquired and used” (Schmitt, 2010, p.47),
such various measures should be provided. Also, it is effective
for teachers to use the target words in teacher talk consciously.
Through such a meaningful interaction between teacher and
students, they may be able to facilitate their vocabulary
retention.
In terms of VLS use among the participants, the result of
the current experiments indicated that the majority of the
participants used the ‘written repetition’ strategy for both
vocabulary learning and the vocabulary tests. As Schmitt (1997)
pointed out, they may just depend on repetition, which is
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 60
generally used among Japanese learners. Another possible reason
may be that ‘written repetition’ does not call for technical
skills unlike other strategies; learners just jot down the words
to memorize them and they are not required to be proficient to
adopt this strategy. That is, the ‘written repetition’ strategy
may be the most user-friendly and all-round VLS, especially for
young learners. Indeed, some researchers reported that beginners
starting to a new FL spontaneously and overwhelmingly use of
silent or written repetition of the target words and its meaning,
but make relatively little use of mnemonic VLS unless trained to
do so (Gu & Johnson, 1996; Lawson & Hogben, 1996).
Actually, it seems that the ‘written repetition strategy’
has some advantages. For example, as Hill (1969) suggested,
repeated copying letters of the alphabet is an effective method
to recognize the letter shapes. Since Japanese has a different
writing system from English, it is definitely important for
Japanese EFL learners to recognize the English letter shapes;
‘written repetition’ would be effective to reinforce this
ability. Furthermore, many researchers claimed the importance of
the link between spellings and phonetic awareness. Papagno (1991)
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 61
revealed that the participants in his study were unable to learn
foreign language words under articulatory suppression, an
interference treatment that selectively affected phonological
short-term memory, while in Ellis and Sinclair’s experiment
(1996), participants who repeated the language aloud scored
significantly higher on vocabulary. From these results, Martin
and Ellis (2012) claimed that working memory and phonological
short-term memory had significant role in vocabulary learning.
In sum, mixing ‘written repetition’ with ‘verbal repetition’
would be a powerful way in order to facilitate effective
vocabulary learning.
However, it is not wise to just depend on the simple
repetition strategies; learners should be familiar with other
strategies gradually so that they can effectively learn words for
various purposes. Although the ‘written repetition’ strategy
seems to have some advantages as referred to in the previous
paragraph, it also has some disadvantages. Indeed, learners are
likely to rely upon a one-to-one correspondence. In addition, in
order to master vocabulary, learners must learn various factors
including multiple word meanings and connotations, derived forms,
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 62
spellings, pronunciations, proper grammatical uses, or
collocations and so on (Nation, 1990). That is, learners must be
familiar with the depth of word knowledge. Although simple
repetition may enable learners to expand vocabulary, it would be
definitely hard to acquire the depth of word knowledge through
one-to-one correspondence. Indeed, as Brown (2007) pointed out,
“rote pattern drills often evoke surface imitation”, shallow
processing like the ‘written repetition’ strategy may not help
learners facilitate deeper vocabulary learning; “a deeper level
of imitation is far more important in the process of language
acquisition” (p.43). That is, better learning would take place
when a deeper level of processing with elaboration is achieved.
In conclusion, it is obvious that they need to adopt appropriate
strategies besides ‘written repetition’ depending on learning
purposes.
Conclusion
Brown (2007) said that teachers would determine the
philosophy of education, teaching style, approach, methods, and
classroom techniques by understanding how the learner learns.
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 63
Indeed, students would not be able to improve their performances
if they do not know what to change and how to change their ways
of learning and they would be lost on the course of learning
without effective supports. The current study revealed that most
content words in the textbooks were not recycled enough, and
majority of young students depended on the ‘written repetition’
strategy for both vocabulary learning and vocabulary test. Taking
account of these situations, language teachers should consider a
teaching plan for vocabulary instruction. Then, it is necessary
for them to provide various types of exercises to facilitate
vocabulary acquisition. Of course, it may be hard to secure
sufficient time for vocabulary instruction in the actual setting;
it is no wonder that four skills are preferentially focused.
However, it is definitely important to organize reasonable
learning systems in which sufficient repetitions are offered with
regular intervals; in addition, additional trainings which would
cover the lack of input in a textbook should be regularly
offered. Moreover, teachers should always encourage students to
make individual efforts, giving reasonable feedback or suggesting
suitable VLSs depending on learning purposes. To achieve this, it
ANALYSIS OF EFL TEXTBOOKS AND VOCABULALRY LEARNING AMONG HIGH SCHOOL STUDENTS 64
goes without saying that it is important to understand each
student’s personality and learning situation. Hopefully, such
rational and supportive learning environment enables Japanese EFL
learners to acquire adequate English vocabulary.
