An
adequate description of the nature of communicative competence is
crucial to instrument content and instrument method (Weir, 1990).
According to Ellis (1994:696), communicative competence is "the
knowledge that users of a language have internalized to enable them
to understand and produce messages in the language".
Several
models of communicative competence have been proposed (Ellis, 1994).
Chomsky (1965) proposed the concept of grammatical or linguistic competence
and highlighted cognitive aspects of human language acquisition and
learning. He distinguished between competence (one's underlying knowledge
of the language) and performance (the realization of language in specific
situations). On the other hand, Hymes (1971), who coined the term
'communicative competence' emphasized social, interactive, and negotiating
process of language. Hymes expanded Chomsky's notion of competence
into communicative competence by including both grammatical rules
and rules of language use (Hymes, 1971; Taylor, 1983).
Canale
and Swain (1980) identified three distinctive components of communicative
competence: grammatical competence, sociolinguistic competence and
strategic competence. Grammatical competence includes one's knowledge
of lexical items, morphology, syntax, semantics, and phonology in
a language. Sociolinguistic competence encompasses the knowledge of
rules governing the production and interpretation of language in different
sociolinguistic contexts. Lastly, strategic competence is defined
as one's capability to sustain communication using various verbal
or nonverbal strategies when communication breakdowns occur. This
model was updated by Canale (1983). He proposed a four-dimensional
model of communicative competence: grammatical, sociolinguistic, discourse,
and strategic competence.
Bachman
(1990) suggested a theoretical framework for communicative language
ability. It includes knowledge structures, strategic competence, psychophysical
mechanisms, context of situation, and language competence. Language
competence is further divided into organizational competence (grammatical
and textual competences) and pragmatic competence (illocutionary and
sociolinguistic competences).
Bachman
(1990), in his schematization of 'language competence' takes a broader
view of the role of strategic competence than Canale and Swain do.
Bachman separates strategic competence from what he calls 'language
competence'.
Agreement
on what components should be included in a model of communicative
competence is never unanimous (Weir, 1993). In spite of many disputes
by applied linguists (Lluda, 2000), this notion of communicative competence
outlined above has proven useful in suggesting specifications for
content, formats, and scoring criteria in communication-oriented language
proficiency assessment (Bachman and Palmer, 1984). However, "it
must be emphasized that they are still themselves in need of validation"
(Weir, 1990:8).
2.2
Communicative Language Teaching (CLT)
According
to Richards and Rodgers (1986), Communicative Language Teaching (CLT)
starts with a theory of language as communication. The classroom goal
of instruction is focused on developing learners' communicative competence.
Thus, learners are encouraged to communicate with target language
through interaction from the beginning of instruction.
In CLT,
meaning is most important. Larsen-Freeman maintains that "Almost
everything that is done is done with a communicative intent"
(1986:132). Accordingly, the process of meaning negotiation is essential
in CLT (Paulston, 1974). In order to encourage learners to communicate
better, errors should be tolerated with little explicit instruction
on language rules (Larsen-Freeman, 1986). Naturally, CLT favours small
group activities by students to maximize the time each student has
to negotiate meaning. CLT employs information-gap activities, problem-solving
tasks, and role-plays through pair and group work (Larsen-Freeman,
1986).
Another
feature of CLT is its "learner-centredness view of second language
teaching" (Richards & Rodgers, 1986:69). According to Savignon
(1991), every individual student possesses unique interests, styles,
needs and goals. Therefore, it is recommended that teachers develop
materials based on students' demonstrated needs of a particular class.
CLT emphasizes
the use of authentic materials in teaching language (Widdowson, 1996).
It also encourages giving learners the opportunity to respond to genuine
communicative needs in real-life situations. This is to help learners
develop strategies for understanding language as actually used by
native speakers (Canale and Swain, 1980).
2.3
Speaking assessment
Testing
oral proficiency has become one of the most important issues in language
testing since the role of speaking ability has become more central
in language teaching (Hartley and Sporing, 1999). Assessment needs
to be theory driven. The concept of validity, reliability and efficiency
affect assessment design (Bachman, 1990). In this section the various
types of validity will be discussed. As well, it will be discussed
how the concept of validity relates to those of efficiency and reliability.
2.3.1
Validity
Spolsky
(1975) stated that validity is the central problem in foreign language
testing.
Validity is concerned with whether a test measures what it is intended
to measure (Weir, 1990). A test of speaking ability in a classroom
setting is usually an achievement test. An achievement test should
have content and face validities (Davies, 1983). Since content validity
asks if the test content matches the content of the course of study
(Bachman, 1990), what teachers can do is to match the course objectives
and syllabus design with the test items. This attitude by teachers
is crucial in a classroom test because teachers may tend to use test
tasks different from the course objectives especially when oral aspects
are involved (Nakamura, 1993).
Face
validity pertains to whether the test 'looks valid' to the examinees,
the administrative personnel and other technically untrained observers
(Bachman, 1990). Face validity is a must in a classroom speaking test,
because the students' motivation is promoted for speaking if a test
has good face validity (Hughes, 1989).
Language
testing can be put on a scientific footing through construct validity
(Hughes, 1989). Bachman (1990) also highlighted that construct validity
is the most fundamental validity for a speaking test. Construct validity
examines if the test matches a theoretical construct (Bachman, 1990).
This cannot easily be handled by classroom teachers because of the
abstract nature of language abilities (Nakamura, 1993).
2.3.2
Reliability
The
concept of reliability is particularly important when considering
communicative language testing (Porter, 1983). Reliability is concerned
with the extent to which we can depend on the test results (Weir,
1990).
Rater
reliability is important to overall test reliability. What raters
need to do for this purpose is to achieve high inter-rater reliability
for these assessments. The degree of inter-rater reliability is established
by correlating the scores obtained by candidates from rater A with
those from rater B. The concern of the rater is how to enhance the
agreement between raters by establishing explicit guidelines and maintaining
adherence to them for the conduct of this rating (Bachman, 1990).
Although
reliability is something raters need to try to achieve in the tests,
it may not be the prime consideration all the time (Bachman, 1990).
It is said that there is a reliability-validity tension. Reliability
offers a possible compromise. It is occasionally essential to sacrifice
a degree of reliability to enhance validity (Davies, 1990). For example,
in certain circumstances, reliability and validity are mutually exclusive.
However, if a choice has to be made, validity is more important for
speaking assessment (Bachman, 1990).
2.3.3
Test efficiency
A valid and reliable test is useless if it is not practical (Bachman,
1990). "This involves questions of economy, ease of administration,
scoring and interpretation of results" (Bachman, 1990: 34). The
context for the implementation of a test is a vital consideration.
Classroom tests should not require costly specialized equipment or
highly trained examiners or raters (Weir, 1993). The tasks should
be the most efficient way of obtaining the information about the test
takers. There is much pressure on teachers to make tests as short
and practical as possible because teachers cannot afford to spend
much time in assessing students' communicative ability. However, "this
should never be allowed to put at risk test validity" (Weir,
1993: 22).
To sum
up, there is a need to develop test formats that provide overall balance
of reliability, validity and test efficiency in the assessment of
communicative skills (Bachman, 1990). Authenticity as a concept has
also been a major concern in language testing (Bachman, 1990). Therefore,
it is considered necessary to briefly examine authenticity.
2.3.4
Authenticity
According
to Bachman (1990), authenticity is defined as a quality of the relationship
between features of the test and those of the non-test target-use
context. There are two approaches on authenticity; the real-life approach
and the interactional ability approach. 'Real-life(RL) approach' tries
to develop tests that mirror the 'reality' of non-test language use.
This approach has been considered as naive because the test setting
itself does not exactly resemble its real-life setting (Spolsky, 1985).
Also "this approach does not distinguish between language ability
and the context in which this ability is observed, since non-test
language performance constitutes the criterion for authenticity and
the definition of proficiency" (Bachman, 1990: 302).
In the
second approach, the authenticity of language tests arises from their
'situational' and their 'interactional' authenticity. 'Situational
authenticity' refers to the relationship of features of the test method
to particular features of the target-use situation. 'Interactional
authenticity' mentions the extent to which an examinee's language
ability is engaged in the test task. Thus, the emphasis in this model
shifts from "attempting to sample actual instances of non-test
language use to that of determining what combination of test method
facets is likely to promote an appropriate interaction of a particular
group of test takers with the testing context" (Bachman, 1990:
317).
Assessment
can be used to improve instruction and help students take control
of their learning (Bostwick and Gakuen, 1995). Accordingly, it is
also necessary to briefly examine 'backwash effect' as a concept.
2.3.5
Backwash effect
This
term describes the effect of testing on teaching: "Assessment
should be supportive of good teaching and have a corrective influence
on bad teaching" (Hughes, 1989:2). Backwash can be harmful or
beneficial. Positive backwash happens when students study and learn
those things which teachers intend them to study and learn (Hartley
and Sporing, 1999). On the other hand, negative backwash means the
converse. For example, if teachers measure writing skills only through
multiple-choice items, then there will be pressure to practice such
items, rather than writing itself. In this case, the backwash would
be negative.
Bachman
(1990) highlighted that positive 'backwash effect' will result when
the testing procedures reflect the skills and abilities that are taught
in the course. Hartley and Sporing (1999) support the rationale and
validity of assessing students communicatively who have been taught
communicatively. By assessing communicatively, teachers would expect
the backwash to be beneficial. If teachers wish students to learn
to communicate effectively in a variety of practical situations, teachers
should test them on these skills. This conscious feedback loop between
teaching and testing, in terms of content and of approach, is a vital
mechanism for educational development (Bostwick and Gakuen, 1995).
2.3.6
Elicitation
The
key to effective oral proficiency testing lies in matching elicitation
techniques with the purposes and constraints of the testing situation.
In the case of school-related speaking assessment, tests are usually
brief and consist of a single elicitation procedure (Madeson, 1980).
There
is a great range of test types, depending on the content of instruction.
For example, some tests use a simple question and answer procedure
to assess communicative matters such as amount of information conveyed,
comprehensibility, appropriateness of vocabulary, and fluency. Other
formats include the guided interview, evaluation during group interaction,
oral reports, dialogues and role-play, skits and drama. While the
latter five are high in communicative face validity, they are difficult
to assess with any consistency (Madeson, 1980).
2.3.7
Scoring
The
techniques for eliciting speech samples must be linked with appropriate
scoring procedures (Madeson, 1980). The decision as to whether to
use a global or specific scoring procedure depends on the purpose
of the test (Jones, 1977).
There
are two contrasting ways of grading student speech; holistic scoring
and objectified scoring. Holistic scoring concentrates on communication
and tends to be selected when the teacher evaluates a wide variety
of criteria simultaneously. The limitation of holistic scoring is
that some teachers find it confusing to evaluate many things simultaneously
(Bachman, 1990); it may be only those teachers with considerable experience
and training who can use holistic scoring effectively.
On the
other hand, specific scoring procedures attempt to identify smaller
units such as appropriateness, fluency, grammar, vocabulary and pronunciation.
Objectified scoring (Bachman, 1990) can be used by teachers with little
specialized training and by highly trained teachers who prefer evaluation
which is consistent and easy to use. For most teachers, objectified
scoring is a practical alternative. However, it is possible to lose
perspective of the overall performance. Even on a speaking test with
objectified scoring, it is good to indicate a very general impression
of a student's performance. This can be done simply by an indication
that the person is "high", "mid", or "low".
The general rating can verify the teacher's objectified score (Bachman,
1990).
2.3.8
Further considerations for scoring
There
are three important suggestions on scoring. One is to use a scoring
sheet. At the left raters can number the test item. Next to the test
number is a short version of the cue. At the right are at least three
boxes for raters to check- the first for 2-point answers, the next
for 1-point responses, and the next for "0" or unacceptable
answers (Bachman, 1990).
Another
suggestion is to score the speaking test immediately if possible.
Usually the scoring of a speaking test is more accurate when it is
done during the process of the test itself. So if they feel comfortable
testing and scoring at the same time, it is recommended that teachers
handle both together. Usually, however, it is difficult for teachers
to handle both. The alternative method is to determine the score immediately
after the test has been administered (Jones, 1977). Furthermore, an
interviewer should not be seen making notes about an interviewee's
performance, either during the interview or any other time (Hughes,
1989). If the examiner is making notes during the test, it can distract
the examinee and create unnecessary anxiety (Nagata, 1995).
The third
suggestion is that if the resources are available, the ideal method
is to have an examiner and a scorer present during the test. The examiner
can administer the test, while the scorer, located in a place so that
he or she cannot easily be seen by the examinee, can record the information
for the score (Bostwick and Gakuen, 1995). Hughes (1989) also recommends
that a second tester be present for an interview. This is because
the difficulty of conducting an interview and keeping track of the
candidates' performance.
2.4
Teachers' perceptions
It
is generally perceived that oral testing is difficult (Jones, 1977)
and it is a perplexing problem for many language teachers (Nagata,
1995). Li (1998) found that the main obstacles cited by Korean English
teachers included a lack of effective and efficient assessment instruments.
According to him, the Korean teachers found it disconcerting that
there were no prescribed, ready-made assessment tools for communicative
competence. Korean teachers also found it difficult to balance content
and language when scoring an oral exam (Myung-sook, 1995, cited in
Li, 1998). Some obstacles had little to do with pedagogical issues,
but included large classes and a lack of time to conduct speaking
assessments (Min-ju, 1995, cited in Li, 1998).
It seems
that teachers need to have assistance and encouragement in trying
communicative assessment. The accurate measurement of oral ability
takes considerable time and effort to obtain valid and reliable results.
Nevertheless, where backwash is an important consideration, the investment
of such time and effort may be considered necessary (Bachman, 1990).
This
chapter has discussed the literature which supports the rationale
and validity of using communicative speaking assessment and shows
the practical constraints in conducting communicative speaking assessment.
Communicative speaking assessment can be difficult and expensive.
However, teachers should always remember that it is not impossible
(Bachman, 1990). In any attempt to improve education, teachers are
central to changes (Frymier, 1987). Teachers are the end users of
a classroom innovation. Teachers' perceptions are a crucial factor
in the ultimate success or failure of that innovation (Kelly, 1998).
Therefore, the study investigated Korean Junior Secondary School English
teachers' perceptions of speaking assessment.
The methodology
of the study will be outlined in the next chapter.
