The terms

discourse

and

discourse analysis

have varieties of

definitions. The definition of discourse itself really depends on the linguists

who discuss about discourse.

➭➯

cording to Rymes, discourse is

language in

use

.

This means that language deals both in forms and functions.

n some

linguistics books discourse is

language beyond the sentence

. The definition

of the term discourse as

language beyond the sentence

similarly appears like

language above the sentence

in other textbooks of linguistics.

➭➵

guably, that

discourse is

language beyond the sentence

or

language above the sentence

is not appropriate to describe the term discourse.

f discourse is only about the

forms, organization, or structure of the language, it may ignore the social

context and the functions of the language itself.

or example, there is a word

than the others.

The term

comes to a question what discourse analysis is.

êë

re are some definitions related to discourse analysis.

ì

irst,

í

rown and Yule

discuss that analysis of discourse is

è

the analysis of language in use

é

and an

investigation of what language is used for.

î

They explain that discourse

analysis cannot be restricted to the independent description of linguitic forms

from the functions of the language. Second,

ï

c

ð

harty defines discourse

analysis as the study of relationship between the language and contexts in

which it is used.

ñ

These two previous definitions have the same point that

discourse analysis refers to the study of the language and its use. Then, Van

òó

jk states that discourse analysis is the form of language which refers to

public speech or more commonly to spoken language.

ô

Van

òó

jk makes a

distinction that discourse analysis frequently deals with spoken language.

õ

n

fact, discourse is language produced in oral and in written communication.

While according to Steve Walsh, discourse analysis focuses on words and

utterances above the level of sentence.

õ

ts main aim is to look at the ways in

which words and phrases function in context as well.

s

t is obvious that classroom discourse is where language

takes place in a classroom. While Rymes identified that classroom discourse

refers to

t

language in use

in classroom context.

s

t is also to understand how

context and talk are influencing each other.

s

t means that the language is used

to communicate in relation to lesson and communication in a classroom.

✇①

cording to

②③

een cited in Rakhmawati as quoted by

annah, classroom

discourse is formed by two components. Those are social context and

academic context.

⑤⑥

Social context deals with the involvement of participants,

and the process of interaction.

esides, academic context deals with the

content of a lesson. To summarize, classroom discourse is the language used

in the classroom or in the context of teaching.

lassroom discourse has many features. Walsh describes that one of

the features is the structure of classroom discourse.

⑤⑤

s

t is important to know

the structures.

irst, it is common and predictable within classroom

interaction. This exchange structure of classroom discourse enables us to

understand the kinds of interaction in a classroom. Second, it is very

frequently used by teachers to see the progress of interaction in

teaching-⑩

ast, it can be used to evaluate the teacher

s role in

classroom discourse as well.

or example, a teacher frequently initiates the

interaction first, and he

she evaluates the students

utterance. The structure of

classroom discourse is beneficial for teachers to analyze their utterances in

teaching.

The structure of classroom discourse typically has the pattern which is

called as an exchange structure. Some writers and practitioners refer to

➼ ➽

R

exchange structure

. The

➼ ➽

R

➺➸

stands for

nitiation, Response, and

eedback.

This structure was first put forward by Sinclair and

oulthard.

➚➪

➼➽

nitiation

means that a teacher usually initiates the classroom discourse.

t can be

opening and closing the stage of lessons, eliciting (gathering information from

students), or checking student

s understanding about the lesson.

Response

is

defined as student

s answers or teacher

s questions.

➼➺

eedback

means the

evaluation or the way a teacher assesses students

response. This exchange

structure typically occurs in teacher-learner interaction in classrooms all

around the world.

There is the other features of classroom discourse stated by Walsh.

There are four features in classroom discourse

control of interaction, speech

modification, elicitation, and repair.

ontrol of interaction means that there is

a control from a teacher or students during interaction in a class, even though

(27)

à á

the roles of teacher and students are not equal.

â

teacher more frequently

controls the classroom interaction than students. The examples of this feature

are managing the topic of communication and turn taking. Speech

modification is that a teacher modifies the speech. Sometimes a teacher

modifies the speech by increasing or decreasing the volume and tone.

ã

n

addition, she

ä

he also may simplify the vocabulary and grammar in speaking.

åæ

icitation is a strategy done by teachers to ask students about their

understanding of the content of lesson. Teachers may ask either display

questions or referential questions. Repair, the last feature, is the way teachers

deals with students

ç

error. The errors can be the grammar, vocabulary, or the

content.

These features usually happens in each classrooms by teachers, and

they are rarely done by students.
