Literature Review

The present study investigated the influence of NESTs on younger learners’

listening performance on communicative tests. To explore the stated research questions,

the relevant literature reviewed in this chapter is separated into three sections: Section

2.1 summarizes the general backgrounds of listening comprehension and focuses on the

aspect of authenticity; Section 2.2 explores the effectiveness of English-native teachers’

authentic input in a co-teaching module; Section 2.3 reviews listening assessment with

three primary approaches to language testing; and finally, major findings and

limitations from previous studies will be summarized in Section 2.4.

2.1 Listening Comprehension

2.1.1. Listening Comprehension Process

Listening comprehension has been under great interest and been investigated from

many aspects for decades among educational researchers. Most researchers in recent

years focus on the cognitive aspect of listening comprehension, which mainly examines

the process of the comprehension (e.g., Kurita, 2012; O’Malley & Küpper, 1989; Rost,

1990; Rubin, 1994; Vandergrift, 1999, 2007). There are two commonly adopted models

of listening comprehension: Anderson’s (1985) three stages of language comprehension

and top-down processing versus bottom-up processing. Anderson (1985) proposed that

8

comprehension is an interrelated and recursive process which involves perceptual

processing, parsing, and utilization. In the first stage, perceptual processing, attention

is focused on the encoding of the spoken message. In the second stage, parsing, words

and messages are utilized to build up meaningful mental representations. The third stage

is utilization, in which the listener relates the mental representation to the existing

knowledge and it is the stage where comprehension takes place if the mental

representation and the existing knowledge are matched.

Based on the aforementioned listening comprehension model, O’Malley and

Küpper (1989) conducted an empirical study to examine whether L2 learners process

information as proposed by Anderson and the strategies used while comprehending

academic texts with a group of high school students in an ESL context using “think

aloud” protocol. The participants were asked to listen to different types of listening

passages including lectures and short stories and think aloud in either Spanish or

English to explain how they understood the listening passages. The result showed that

the listening comprehension presented by the participants was consistent with the three

stages proposed by Anderson. Furthermore, the strategies used by effective and

ineffective listeners were different and were applied in various ways depending on the

phase of comprehension.

Another model of listening comprehension deals with the idea of top-down

processing and bottom-up processing. Top-down processing refers to the application of

background knowledge in understanding the meaning of a message, while in the

bottom-up processing, the understanding of each of the linguistic characteristics from

the incoming input is used as the basis for understanding the whole message. It is

generally agreed by many researchers that listening comprehension occurs when both

top-down and bottom-up processes continuously interact (Vandergrift, 2007). For

example, Chien and Wei (1998) investigated the strategies used by different proficiency

levels of college EFL learners in listening comprehension with two sets of authentic

listening materials in recall tasks. The result showed that to match the new information

with what is already known (top-down processing) and to infer meaning between words

or phrases (bottom-up processing) are two most effective cognitive strategies for

understanding the aural input. Chang and Read (2006) also evaluated the influence of

listening strategies on the listening performance of college EFL learners. The listening

comprehension test they applied was a section of TOEIC listening comprehension test

which was recorded by native-speaking ESL teachers with diverse accents. They found

that the most effective type of support was providing information about the topic, which

is more of a top-down processing; vocabulary instruction was the least useful form of

support, which is more of a bottom-up processing.

10

Despite the fact that all the empirical studies mentioned above explored listening

comprehension strategies used by learners with different tests or tasks and put much

emphasis on the process of comprehension, the listening constructs, that is, the

definition of listening competence and the listening tasks, in the aforementioned studies

were neglected. As Chapelle (1999) pointed out that there are two ways to define a

construct: (1) to define the competence, that is, the abilities that we believe the

test-takers should acquire and (2) to define the tasks that we think test-test-takers should perform.

However, either way was applied in the abovementioned studies. When using listening

tests to conduct research, the construct validity should be of primary concern

(Vongpumivitch, 2007). In terms of the listening assessment, further literature review

will be presented in the later section. Apart from the listening constructs, the materials

that learners process during the comprehension in both the empirical studies and the

real-life situations are also of importance considered by many researchers (e.g., Buck,

1995; Field, 2010; Goh, 2002; Rubin, 1994; Vandergrift, 2004) which were also

overlooked in the above-reviewed empirical studies.

2.1.2. Authentic Input for Listening Comprehension

Despite the fact that the major focus of the recent listening comprehension studies

has been laid on the process of the comprehension, there is a body of research on

listening comprehension about how learners interact with authentic input (Rubin, 1994).

11

Some researchers examined the text characteristics such as the text type of the listening

passage (e.g., Shohamy & Inbar, 1991), the acoustic variables (i.e. speech rate) of the

authentic input (e.g., Griffiths, 1991); others from the aspect of interlocutor

characteristics such as the gender of the speaker (e.g., Markham, 1988).

The term “authentic” was defined by Rogers and Medley (1988, p. 468) as

“language samples that reflect a naturalness of form, and an appropriateness of cultural

and situational context that would be found in the language as used by native speakers.”

As Vandergrift (2007, p. 200) pointed out that “exposure to authentic-type texts and

natural speech rate is preferred by L2 learners and can be beneficial for listening

development.” Such statement coincides with Rogers and Medley’s (1988) study that

they believed students should experience the language which is used for real

communication by native speakers. It is necessary to incorporate authentic materials in

the activities developed for language learning. After all, the ultimate goal for language

learning is to facilitate L2 learners to comprehend the target language in real-life

situations (Rogers & Medley, 1988). This might also explain why all the empirical

studies reviewed adopt authentic listening materials when examining listening

comprehension.

However, not all studies present such point of view. For example, Teng (2001)

examined the effects of modified sentences and the speech rate of listening texts on the

12

listening comprehension of a group of 168 EFL freshmen in college. The results showed

that students performed better when they listened to the tests that were syntactically

modified. Besides, students performed better in the slower version of the input instead

of the original version. The researcher concluded that the use of modified listening

passages should be applied in the listening tests. It seems that mixed statements have

been claimed considering the use of authentic or modified listening materials when

examining listening comprehension. Thus, the present study intends to investigate how

the authentic input of NESTs in a co-teaching model influences younger learners’

listening proficiency.

2.2 Co-teaching Native-English-Speaking Teachers (NESTs) and

Non-Native-English-Speaking Teachers (NNESTs)

As the effectiveness of NESTs as an authentic input in language learning

classrooms has long been a controversial issue, the advantages and disadvantages of

NESTs and NNESTs have been under great interest for decades among educational

researchers (e.g., Barratt & Kontra, 2000; Benke & Medgyes, 2005; Florence Ma, 2012;

Herbert & Wu, 2009; Medgyes, 1992). The findings suggested that NESTs and NNESTs

have their own strengths and weakness. NESTs are valued for their authenticity and

positive personal traits (Barratt & Kontra, 2000). They are good at teaching

conversation classes, providing perfect linguistic models, getting learners to speak,

13

being friendly (Benke & Medgyes, 2005) and creating relaxing and lively classroom

atmosphere (Poon & Higginbottom, 2000). However, NESTs are mostly criticized for

being unable to identify language learner’s common problems (Barratt & Kontra, 2000),

lack of expertise in English language teaching (Chang, 2007), and their

non-examination-oriented teaching styles (Florence Ma, 2012). In contrast to NESTs,

findings pointed out that NNESTs are appreciated for understanding students’ learning

difficulties and needs (Florence Ma, 2012) and serve as models of successful language

learners (Medgyes, 1992). Nonetheless, it is suggested that they are usually poor in

pronunciation and tend to have traditional and textbook-based teaching styles (Medgyes,

1992). In short, it seems that NESTs and NNESTs make up for each other’s

disadvantages, which “make both groups of teachers serve equally useful purposes in

their own terms” (Medgyes, 1992, p. 349). Thus, having NESTs and NNESTs to

co-teach can help consolidate their qualities and make a learning environment which

benefits students’ English learning.

Co-teaching is defined as “two or more professionals delivering substantive

instruction to a diverse, or blended, group of students in a single physical space” (Cook

& Friend, 1995, p. 2). It is a commonly applied teaching model in East Asian native

English teacher programs, including Hong Kong NET (Native-speaking English

Teacher) scheme, EPIK (English Program in Korea) program, Japanese JET (the Japan

14

Exchange and Teaching) scheme, and etc. Taiwan, as well, utilized co-teaching in

different programs which include NESTs, such as MOE’s FET (Foreign English

Teachers) program, Fulbright’s ETA program, King Car’s Schweitzer Program, etc. As

findings suggested that co-teaching provides more opportunities for students to use the

target language (Barratt & Kontra, 2000; Carless & Walker, 2006), creates a more

pleasant learning environment (Buckley, 2000), and helps facilitate learners with low

English proficiency (Storey et al., 2001).

Although co-teaching seems to help facilitate learners with low English

proficiency, studies directly assessing the effects of authentic input provided by the

NESTs in a co-teaching model are still very limited (e.g., Lin, 2017; Wu, 2015). Wu

(2015) explored the effectiveness of different co-teaching models between NESTs and

NNESTs on sixth graders’ English listening and speaking performances in an EFL

context. There were three types of co-teaching in the study: (1) NEST dominated the

teaching while NNEST facilitated, (2) station-teaching, and (3) team-teaching. The

participants were given a pre-test and followed by a post-test after 10 weeks of different

co-teaching instruction. The result showed that NEST dominated the teaching while

NNEST facilitated and station-teaching both had significant effects on students’

listening and speaking performances. The team-teaching model had a greater effect on

students’ speaking abilities; however, it only had a limited effect on students’ listening

15

abilities. In general, NESTs in co-teaching models have a positive effect on language

learners. Lin’s (2017) study also supported such a finding. The study investigated the

influence of NESTs and NNESTs’ co-teaching on Taiwanese students’ listening

comprehension. The results indicated co-teaching by NESTs and NNESTs greatly

impacted young EFL learners’ listening. Such co-teaching influenced not only learners’

listening comprehension, but also their performance on different questions types such

as those requiring English listening and reading at the same time. Learners with longer

co-teaching experience performed better on question types requiring English listening

and reading. In short, it seemed that the authentic input provided by the NESTs did have

a positive effect on learners in a co-teaching model.

2.3 Listening Assessment

Listening comprehension is a complex and active process (Vandergrift, 1999). A

number of theories have been established to explain the construct for such process and

researchers has been turning these theoretical notions into actual practice, that is, the

listening tests. According to Buck (2001), there are three major approaches to language

testing: the discrete-point, integrative and communicative approaches. The approaches

will be reviewed in the following sub-sections.

2.3.1 Discrete-point Testing

Discrete-point testing is based on the theory proposed by Lado (1961). He assumed

16

that it is possible to identify the isolated elements of language (i.e., grammar,

vocabulary, and pronunciation) and to test each of these items separately. He believed

that by testing a representative item of the language can estimate learners’ language

proficiency. Typical discrete-point tests include phonemic discrimination tasks,

response evaluation tasks, and paraphrase recognition tasks (Buck, 2001).

However, the opponents of the discrete-point tests pointed out that the actual

function in communication might not be evaluated through discrete-point testing (e.g.,

Carroll, 1961; Oller, 1975). Oller (1975) claimed that the assessment of the individual

items in a language is no better than the language as a whole for an item cannot

represent the overall proficiency of a learner’s language ability. Both Carroll and Oller

advocated that integrative test is a better approach to assessing language learning.

2.3.2 Integrative Testing

In contrast to discrete-point tests, integrative tests are intended to evaluate L2

learners’ language abilities as a whole. Oller (1973, p. 37) explained that “whereas

discrete items attempt to test knowledge of language one bit at a time, integrative tests

attempt to assess a learner’s capacity to use many bits all at the same time.” The

theoretical notion associated with integrative testing is that listening is to process texts

in real time, that is, to interpret the semantic meaning. Some well-known integrative

tests are the close test, dictation, and gap-filling (Buck, 2011). The problem with

17

integrative tests is somewhat similar to discrete-point tests in the way that both types

of the test tend to evaluate language as an individualized item as in discrete-point tests

or as an isolated event as in integrative tests. When language processing is considered

to be an isolated event, learners merely get the fundamental linguistic information in

the message without relating to the context.

2.3.3 Communicative Testing

With the rise of communicative teaching, communicative testing was developed

in response to the trend. Communicative testing is based on the theoretical notion that

language proficiency is seen as communicative competence (Hymes, 1972). That is, the

test should be less concerned with how much a test-taker knows about the language,

but more about how he or she can apply such language to communicate. According to

Widdowson (1978), communicative tests should test the use of the language for its

communicative function, rather than usage. Carroll (1980) also pointed out that the use

of language is the objective while the mastery of the usage of that language is a means

to achieve that objective. In communicative tests, it is important to identify whether

learners can use the target language to communicate in real-life situation instead of

knowing the correct usage of the grammar. In other words, a communicative test tests

the “use of language in ordinary situations” (Morrow, 1979, p 148).

The most salient characteristics of communicative tests include (1) authentic texts

18

(2) communicative purpose and (3) the authentic tasks used in the tests. In terms of

authentic text, Brindley (1998, p. 175) suggested that the test should include

conversations, narratives, directions and talkback exchanges. For example, Buck (1990)

conducted a research study which used several communicative tests. In one of the tests,

students were told to imagine that they were going to England for a vacation, and they

called the Tourist Information center to ask for the tours in London. Students listened

to the man who worked at the center and based on the passage to fill in the missing

information, a total of 12 questions, in the grid. The questions asked include “What is

the speakers’ recommendation of a full day bus tour?” and “When will the Thames

River tour depart?” In respect of communicative purpose, “the language use takes place

for a definite communicative purpose” (Buck, 2001, p. 89). That is, test-takers should

well understand the purpose of listening. Possible tasks reflecting communicative

purposes could be asking for and giving personal details such as names, ages, etc., or

identifying and describing simple objects such as shape, size, weight, color, etc.

(Cambridge English Certificate Handbook for Teachers, 2018). As to the authentic tasks

used in the test, some people argued that listeners do not perform any task in real-life

situations; however, the idea is that the test tasks should reflect the real-world listening

situation (Buck, 2001). For example, the test-takers were asked to tell a simple story

which happens in everyday lives with the help of pictures and matched a list of

19

illustrated words or names with a set of pictures, such as a picture of parents, a picture

of uncle, and a picture of daughter, by writing the letter of the correct picture in a

corresponding box. (Cambridge English Qualifications Hand book for Teachers, 2018).

Given the interest in communicative language teaching nowadays, it is not

surprising to find that many of the standardized tests such as TOEIC, TOEFL Junior

tests and Cambridge English: Young Learners tests aim at evaluating learners’

communitive ability. Weir (1993) provided a comprehensive taxonomy of

communicative listening sub-skills. He categorized the sub-skills in four aspects (see

Table 1). The four aspects included (1) direct meaning comprehension, such as listening

for gist, listening for specifics, (2) inferred meaning comprehension, such as making

inferences and deductions, relating utterances to their social and situational contexts,

(3) contributory meaning comprehension, such as understanding phonological features

and discourse markers, (4) listening and taking notes.

20

Table 1. A Taxonomy of Communicative Listening sub-skills (Weir, 1993).

Direct meaning comprehension - listening for gist

- listening for the main idea(s) or important information; and distinguishing that from supporting detail, or examples

- listening for specifics, including a recall of important details

- determining a speaker’s attitude or intention towards a listener or a topic Inferred meaning comprehension

- making inferences and deductions

- relating utterances to their social and situational contexts - recognizing the communicative function of utterances

- deducing the meaning of unfamiliar lexical items from context Contributory meaning comprehension

- understanding phonological features

- understanding grammatical notions such as comparison, cause, result, degree etc.

- understanding discourse markers

- understanding the main syntactic structure of clauses or idea units - understanding cohesion, especially reference

- understanding lexical cohesion, especially lexical set membership and collocations

- understanding lexis Listening and taking notes

- ability to extract salient points to summarize the text - ability to select relevant key points

21

As each approach has its supporters and opponents, there is no panacea for testing

learners’ language proficiency for the process of language is too complex. Farhady

(1982) also indicated in his study that there might be some other factors such as test

takers variables including their characteristics, educational and family backgrounds,

which were not directly related to language proficiency but should also be taking into

consideration when applying tests on L2 learners. However, given the interest and trend

in communicative language teaching nowadays, the present study adopted a

communicative testing approach and tests so as to investigate the listening

comprehension of L2 learners of younger students throughout Taiwan with the

authentic input of NESTs in a co-teaching model.

2.4 Synthesis

As more and more native speaker-oriented programs have been gradually

incorporated into Taiwanese’s educational settings, a new issue considering the

incorporated into Taiwanese’s educational settings, a new issue considering the
