CHAPTER I
INTRODUCTION
1.1 Problem
Background
Language is a tool used by humans as the way to communicate or interact. Languages become the
most important in human life. Without language, we will not be able to interact
or relate to other human beings. Own language and characters have different
types, depending on his or her residence. Nevertheless,
judging from its functional all the same language, namely as a means of
communication or interaction.
Many of his countries make
to each other to make a decision, which set one language as a means of international communication. Based on the conclusions of the above, English has been established as a means
of international communication. So those, all country are required to teach English to his people. English skills have four skills,
listening, speaking, reading and writing. And writing is the each one
main aspect of English course, it’s very important for the students. Writing
makes the students are able to write something which related with the students’
minds and it consists of some various genres. And they need to master about
Vocabulary compound words. But, factually some of the senior high school, most
the students finds the difficulties in their own vocabulary mastery. For
example, until this time they are difficult to write something through the
paragraphs, especially to the descriptive text, it happens because the number
of them, they do not master about vocabulary, and get confused about simple
present tense. The students do not understand about descriptive text where as
they try to make it, as the researcher think that vocabulary and simple present
tense mastery are the aspects which very important to make a written through
the text and the students need to master about that all aspects if they want to
write the paragraphs in descriptive text.
From those statements above in this writing
the researcher concludes that before pre-survey at the tenth grade of SMA N1
Seputih Banyak in academic year 2012/2013, and takes focused of the correlation
of simple present tense, vocabulary in term compound words mastery and the
students’ writing ability of descriptive text.

CHAPTER II
THEORETICAL FRAMEWORK
2.1
Previous Research Overview
In this
research, the researcher overviews about two previous researches before, they
are:The first one is The Correlation of Students’ Simple Sentence Mastery and
Paragraph Writing Ability at SMK Muhammadiyah 2 Metro, by Nova Cahya Sari. This
research is to know whether there are significant correlation of students’
simple sentence mastery and paragraph writing ability. She was identified some
problems to do this research. There are: 1) students’ ability in writing by
using English language is less. And 2) students’ are difficult to develop their
ideas in form of writing in paragraph. She said that in writing a text we must
be able to use a good language and we also must be able to arrange good
sentence grammatically in order the reader understand about the content of
writing.
The
second previous research is conducted by Siti Karimah, and titled : The Student
Mastery On The Simple presents tense, compound sentences mastery, with their
ability in Writing descriptive Text at The Tenth Grade Of Senior High School
SMA PGRI I Tumijajar 2008/2009”.
The different between those two
previous researches with this research are:
The
first, she did the research to know the student mastery of simple present tense
in writing descriptive paragraph. She has that the students have not understood
the simple present tense perfectly. The students get the difficulty to choose
present from in their writing descriptive paragraph.
The
second, she did the research you know the students teaching learning process in
mastering the simple present tense through descriptive text writing still not
maximum yet because the students have not understood yet the simple present
tense perfectly, they get difficulty in writing descriptive text and get
confused about the structure and grammar.
Followed the
previous research above, the researcher
is interested to do the
research under the tittle the correlation between students’ simple present tense, compound words
mastery and their descriptive
writing paragraph ability at the tenth grade class of SMA N1 Seputih Banyak academic
year 2012/ 2013.
2.2
Theoretical Review
The researcher takes some concepts to support
the research as follows:
2.2.1
Concept of
Simple Present Tense
Simple Present Tense is the most popular
tense in using. According to Azar (2005:60) simple present tense is
generally used to express event or situations that exist, always, usually,
habitually. It means that if we will express situation that exist, always,
usually, habitually we should using the simple present tense. And the simple
present tense is one of tenses which is we should master if we will make a
descriptive paragraph.
Simple present tense has pattren, there
are:
a.
Verbal sentence
Formula :
(+) S + V1 ( s/ es) + O/C
(-) S + do/ does + not + V1 +
O/C
( ?) Do/ does + S + V1 + O/C
(-?) Does / do + S + Not + V1
+ O/C
Example:
(+) My
mother cooks the cake in the kitchen.
( - ) My
mother does not cook the cake in the kitchen.
( ? ) Does
my mother cook the cake in the morning?
Notes : S/ ES : he, she it
Does : he, she, it
Do : they, we, i ,you
b.
Nominal sentence
Formula : (+) S + TOBE ( is, am are) + Adjective/
Adverb
(- ) S
+ TOBE ( is, am are) + not + Adjective/
Adverb
(? ) TOBE ( is, am are) + S +
Adjective/ Adverb
(-?)TOBE ( is, am are) + S +
not + Adjective/ Adverb
Example :
( + ) Justin Bieber is
handsome boy.
( - ) Justin Bieber is not handsome boy.
( ? ) Is Justin Bieber
handsome boy?
Useless of simple present
tense:
Use time signal
a) Adverb of time = put on first or least of
sentence
Every day every / each
Every week in the morning
Every month at sevent
Every year once / twice a day
b) Adverb of frequency = put on after to
belajar or before verb
-
Frequency
adverb follow am, is are:
Always, usually,
often, sometime, seldom, raely, never.
Based on the
data, the simple present tense is used to express daily habit or usually
activities.The simple present tense is also used to express present tense time.
Here, in indicates present time which many non action verb, especially those
expressing state or conditions.
2.2.2
Concept of Compound
Word Mastery
The words in the
English language, especially
adjectives and nouns, can be
combined in a composite construction (compound structures) in various ways. And when combined word is formed, then they have a meaning or meanings of
new words. One sure way to know
the combined words in term compound
words by using a good
English dictionary to find and learn the words of the joint.
There are three
forms of compound words:
1. Closed form(combined words), eg,secondhand, softball, keyboard, notebook, etc.
2. Hyphenated form, for example: his daughter-in-law, master-at-arms, six-pack, etc.
3. Open form(individual words), eg, post office, real estate, middleclass, etc.
Compound words, such as a high school and the peanut butter, as opposed to the wearing of a word or described by adjectives, such as: a little school and the yellow butter. Take a look in the dictionary, compound words always have a special meaning.
The incorporation of the word often uses hyphens (-) to avoid confusion or false meaning, for example: old-furniture salesman, part-time teacher, the highest-priced car, etc. Adverb or adverb sending in-ly do not use a hyphen when combined with other words, for example: a weekly news paper, a highly rated bank, a partially refunded ticket.

Hyphens are also used
to describe a person with age, such as my six-year-old son. However, if the age is placed after the person, then
a hyphen is used: my son is six
years old.
From statement above it can be
confirmed that Compound words are two words that join together and
form a new meaning. But
every word has a meaning that is not far away.
2.2.3 Concept of Writing
Descriptive
Chackraverty and
Guantum (2003) state that “the writing is an important part of language
learning is essentially a reflective activity that requires enough time to think
about the specific topic. The analyze and classify language to structure. This
idea in this view writing is not a product but an activity of a mental process.
The definition
of descriptive text is text with says what a person or a thing is like. Its
purpose is to describe and reveal a particular person, place or thing. It is
clear that descriptive text only shows the fact.
The generics
structures of descriptive text are: identifying the phenomena to be describe,
and describing the phenomenon in parts, qualities and characteristics; the
language features of descriptive text are: using attribute and identifying
process, using adjective and classifiers in nominal group, and using simple
present tense.
It can be
concluded that descriptive text aims at giving vivid details of how something
or someone looks. A descriptive text tells the reader what the thing is, or
what the thing does. A description should be so unique that a description of
one thing should be different from a description another thing. On other words,
descriptive text is not used the generalization. All different, reader should
be able to show the same thing being described in the text. The Lexicon-
grammar text is dominated with simple present tense. This is due to the factual
nature of a descriptive text. The text only shows fact. The clause system is
dominated with relational and material process. Relational process is much
employed do show identification of the thing being describe, while material
process is used to show what the thing does. Because descriptive text show the
attribute of the thing, most clauses us adjective the adjective are mostly
descriptive rather that attitudinal. Descriptive text usually also show part-
whole relationship. When describing a guava tree in front of your house, for
example, the description should cover the description of the whole tree and its
part like the trunk, the branches, leaves and many other parts.
Descriptive
gives sense impressions of the feel, sound, taste, smell and look of thing,
emotion maybe describe too: felling such as happiness, fear, loneliness gloom
and joy. Descriptive helps the reader through his/her imagination, to visualize
a scene or a person, or to understand a sensation or an emotion (Wishon and Burk, 1989:128)
In senior High School
level, the students study about the
purpose, generic structure and language
features of the descriptive text they are:
Purpose: to describe a particular
person, place or thing in detail.
GenericStructure:
1.Identification: identifying the phenomena to be describewith says what a
1.Identification: identifying the phenomena to be describewith says what a
person or a
thing is like.
2.Description: describing the phenomenon in parts, qualities, or/ and
2.Description: describing the phenomenon in parts, qualities, or/ and
characteristics.
3.
Language Features: Using Present Tense
Based on the
statement above, descriptive text is a text which says what a person or things
is like. Its purpose is to describe and reveal a particular person, place, or
thing.
2.3 Thinking Framework
There are 3 variables in this research. They are 2
predictor variables X1 and X2, and criterium variable (Y ). They are as follow:
2.3.1
The Correlation of Simple Present Tense, Compound Words Mastery and the Students’ Writing ability of Descriptive text
Writing skill is one of fourth skill in learning language. They are
listening, speaking, reading and writing. Writing skill is the most difficult
skill between the others. Because in writing, the students should not only
learn the vocabularies and structure, but they should understand the way to
express their idea. In writing, the readers are not faced with the writer
directly therefore, the writer has to communicate the message clearly.
The teaching
writing, especially in descriptive paragraph often makes the students feel so
difficult because they do not master both tenses which uses on it there are simple present tense and vocabulary
in term compound words and it causes them difficult to express their idea. In
this case, the teacher should use the better technique to increase students’ simple present tense.

Hypothesis
Based on the theories, the researcher formulated the hypothesis as
follows:
1)
There are positive and significant correlation between students’ simple present tense
mastery and the students’ writing ability of descriptive text
2)
There are positive and significant correlation between
Compound words mastery and the students’ writing ability of descriptive text
3)
There are positive and significant a correlation of students’ simple present
tense,
Compound words mastery and the students’ writing
ability
of descriptive text simultaneously.
CHAPTER III
RESEARCH METHOD
3.1
Research Design
In
this research the researcher
used this is quantitative research used correlation study. That is one of ex
post facto design. Correlation study here means that the writer used one group
to be tested and takes the data without giving any treatment. The researcher
uses this design because he tried to find out the direct relationship between
the predictor and criterium variables from a group of
students who give the data on two different variables without giving any
treatment or control.
This
research, the researcher used
tests to get the data of simple present tense mastery,compound words mastery and the students’ ability
in writing descriptive. After getting the data, the researcher analyzed it and then gave the
description whether there is a significant correlation of simple present tense
mastery (X1), compound words (X2),as the predictor and the students’ ability in writing descriptive(Y) as the criterium variable.
The Design of this research is:
T1 T2 T3
( Hattach and Faradhy, 1982:
P.27 )
à Test 1 x1® y
à Test 2 x2® y
à Test 3 x1® x2 ®
y
Note:
Test
1 : Test simple present tense mastery
Test
2 : Test vocabulary mastery
Test
3 : Test writing descriptive
It means, in doing the
research, the researcher will use test of simple present tense mastery (T1
), compound words
mastery (T2) and
then it is continued by test of writing descriptive (T3). The tests
are proposed to find out the students' simple present tense mastery, compound
words mastery and the students’ ability in
writing descriptive. The researcher did not give the third test for the
students who got low score. The researcher hopes after conducting those tests.
The students will know the level of their simple present tense mastery, compound
words mastery and the students’ ability in
writing descriptive especially for the students who have low ability in simple
present tense mastery, compound words mastery in
the students’ ability in writing descriptive.
3.2
Research Variable
The researcher has determined
three variables of the research that while is investigated, they are:
1)
The criterium variable of this is the students
ability in writing descriptive that is symbolized by ( y );
2)
The predictor variable of this research is the
students simple present tense mastery that is symbolized by ( X1 );
3)
The predictor variable of this research is the
students’ compound words mastery that is symbolized by (X2).
3.2.1 Conceptual Definition of the
Students’ Mastery in Simple Present Tense
The simple
present tense is used to express daily habit or usually activities. The simple
present tense is also used to express present tense time. Here, in indicates
present time which many non action verb, especially those expressing state or
conditions.
3.2.2 Operational Definition of the Students’
Mastery in Simple Present Tense
In
simple present tense test which consists of 40 items. This test is multiple
choices which consist of four options (A, B, C, and D). This test used to the
students’ simple present tense mastery.
3.2.3
Conceptual
Definition of the Students Compound Words mastery
Compound words are
two words that join together and form a new meaning.
But every word has a meaning that is not far away.
3.2.4
Operational Definition of the Students Compound Words Mastery
In
vocabulary in term compound words test which consists of 40 items. This test is
cross-puzzle and essay. This test used to the students’ vocabulary mastery in
term compound words.
3.2.5 Conceptual Definition of the
Student’s Their Ability in Descriptive Text
Descriptive text
is a text which says what a person or things is like. Its purpose is to
describe and reveal a particular person, place, or thing.
3.2.6 Operational Definition of the Students’Their
Ability in Discriptive Text
In the writing
paragraph test, the researcher would like give essay test. The students must
make a paragraph consist of 200 words. The topic of it is “Free”. This test
used to know, how far the students’ can make in paragraph writing well
according their ideas.
3.3
Research Population, Sampling Technique and
Sample
3.3.1
Population
The
population of this research is the grade tenth of SMA N1 Seputih Banyak which
consists of two classes. There are X1, X2, X3, and X4. Total sum of the whole students of grade tenth is 100 students.
3.3.2 Sampling
Technique
The
researcher takes randomly sampling. To get sampling from researcher population,
the researcher does some steps as follows:
1.
The whole student of grade tenth
2.
Write the classes in piece of paper
3.
The paper wrapped and then put into a jar
4.
Then, there is a little slit on the jar’s mouth to let
one piece wrapped out
5.
The paper which comes out firstly is as the sample of
this research.
3.3.3

Validity
and Reliability of Instrument
3.4.2.1
The Validity
3.4.2.1.1 The Validity of Vocabulary Mastery and
Simple present Tense
Mastery
To
get the validity of the test the researcher uses internal validity. Validity is
a standard or criterion that shows the instrument is valid or not. A test is
valid to extent that is measures what it claims to measure (Arikunto,
1985:145). To calculate the validity of each item the writer used the product
moment formula:
Where:
Rxy = coefficient of
correlation between x and y variable or validity of each item.
N = the number of
students/subject participating in the test.
∑x = the sum of score in each item.
∑x2 = the sum of the square score in each
item.
∑y = the sum of total score each students.
∑y2 = the sum of square total score from each
students.
∑xy = the sum of multiple of score from each
student with the total score in
each item.
3.4.2.1.2
The Validity
of Students’ Ability in Writing Descriptive
The researcher
was using essay writing as the test to number about the students’ skill in
descriptive text. They have to write something through the paragraphs as the
criteria in descriptive text which consisted of the main contents are
orientation, even and re-orientation, and about generic structure in
descriptive text. Every paragraph had point if all the paragraphs were great,
and the students would get 100 score.
3.4.2.2 The Reliability
3.4.2.2.1
The Reliability of
Vocabulary Mastery in term of Compound
Words and Simple
Present Tense Mastery
The test can be said reliability if the test has been given in
some place but the result of the test is the same with another place. To know
the reliability of the test, the researcher will employ the formulation alpha
of Arikunto (2006:196), as follow:
Note:
= Coefficient correlation regularity level
(reliability)
n =
Number of items.
= Total score of each item
= Total Variant
For finding the Variant formula, the researcher will use the
formula below:
Note:
= Total variant
= Total items which are
quadrate
= The total sum of the quadrate
items
= The number of
items
The other words then from calculation result of interpreting the
coefficient correlation according to Arikunto (2006:276) as follows:
Between 0.800 – 1.000
very high
Between 0.600 – 0.800
enough
Between 0.400 – 0.600
fair
3.4.2.2.2 The
Reliability of Students’ Ability in Writing Descriptive
To know whole
reliability of descriptive writing of diary the researcher will use inters
rater to give the score of students’ work. There is another rater who give
score the students’ work. The score of Students work are divided by two. The Researcher also use single test single trial method to know
the reliability of descriptive writing test. The formula will use to correlate
the result is HJ X Fernandes cited in Arikunto (2006:201) formula as follow:
Description:
K : Coefficient of
agreement
S : agreed, the same code
for the same object
N1 : Number of
code that made the rater I
N2 : Number of
code that made the rater II
After going through several procedures, the formula is further
refined, known as Rough Suitability Index (CCI) with as the same code, and N is
the number of objects being observed. The smaller the value of KK is a list of
checks or instruments of observation are more reliable.
3.5
The Data Collecting Technique
The data collecting for this research is gained from the student test result. The
tests are intended to measure the students achievement in students
mastery of simple present tense,
vocabulary in term compound wordsand their ability in descriptive text to express their part
activities in writing.The prosedure
of tests are as follow:
Test to measure student’s
achievement in vocabulary the kinds of the test administrated is essay,
students’ mastery of simple present tense the kind of test administrated is multiple choice, in which the students are aksed to
choose the correct one of four options offered of each question.
The students
would get the highest score if they could write the right descriptive text which shoud be consisted with the
criteria as follows:
-
Identification
-
Description
-
Language Features
The classes of those above scoring criteria in descriptive, they have some categories.
Adaptedto Tribble’s statement and He
says that “in scoring the students’ writing ability, the researcher used
analytic rating scale. He describes thus classes ofcriteria throughout the table which it can be seen at appendix 6, and testing for this writing descriptive text it applies at appendix 3.
3.6
Data Analysis Technique
In
analysis the data, the writer will use the descriptive qualitative research.
The data is taking from the student’s mastery in simple present tense and the
student’s their ability descriptive text test. Then, the result of scoring of
both the researcher and the other were added and divided by two. After the
researcher giving the test and finding the result of the test will be taken by
using normality test and homogeneity test.
3.6.1 Normality test
In this research, to
meansure normality test is used the formula as follows:
Ho : Data normality distributed
Ha : Data abnormally distributed
Normality test used
is Kolmogrov (mirnov test in kolmogrov s mirnov test assusmes that variable
distribution has continue, the formula is as follows :
D
= max
Where:
Fo(X1)
: Distribution function of cumulative frequency from theoretic in Ho
condition
Sn (Xi)
: Distribution function of cumulative frequency from observation as many
as n.
By comparing D toward D kolmogrovsmirnov with
significant level X
If D<D table so reject Ho and if D>D
table so accept Ho
The decision is also can take based on
significant score if the significant score < X so reject Ho So also in the
control
·
Reject Ho if significant score less than ( <
) 0, or it means the distribution of data is not normal.
·
Accept Ho if significant score more than ( >
) 0, or H means the distribution data is normal.
3.6.2
Homogeneity
test
The
objective of homogeneity test is to know whether the sample is taken from
homogeny Varian population or not.
Homogeneity
is tasted by using one way ANOVA,
The
formula is as follows:
Zit = Yit –Yi
Where:
Yit : the
sample score in every variable
Yi : the
main of sample
With
critical value F (α, k-1, n-k)
Criteria :
·
If probability (sig) more than ( > ) 0,05 Ho
is accepted;
·
If probability (sig) more than ( < ) 0,05 Ho
is receipted;
3.6.3 Correlation Test
Correlation test usually used to search a correlation
and direction of correlation between groups of data. Correlation coefficients
has a value between -1 until 1, if coefficient value of correlation approach
absolute value 1, showing that there is a strong correlation between both of
variable that correlated. But, if coefficient value of correlation more and
more approach 0 that means show that there is a correlation which not linier.

Commonly, known that are two kind of correlation
namely; bivariate correlation is a correlation model that used just for know
about the correlation between both of variables. And then, partial correlation
is a correlations model that used to condition when measure of correlation
between two variable.
3.6.3.1
Bivariat Correlation
Hipotesis
test used correlation technique. Correlation test between or variable and
predictor variable and criterium variable (Y, X1), (Y, X2), or between
predictor variable (X1, X2) are counting used the correlation formula is
product moment because the result of data is interval data. The formula is :
rxy =
There are ranges of correlation value based on Young:
·
0, 7 – 1, 00 positive or negative, showing of
high degree of correlation.
·
0, 4 – 0, 7 positive or negative, showing of
substantial degree of correlation.
·
0, 2 – 0, 4 positive or negative, showing of low
degree of correlation.
·
<0, 2 positive or negative, showing of
ignored correlation.
(Basrowi dan
Soenyono, 2007: 109),
3.6.3.2 Partial Correlation
1). (A First Order Partial
Correlation)
Parsial correlation test is the first step
correlation test between one predictor
variable with criterium variable that control with other predictor
variable. This testing used to getting correlation index number which not iffected other variables.
This testing used to get index number and will using to count double
correlation. The formula is:
Description

|
Correlation between variable Y (criterium) with of variable X1 (predictor) with
controlled by variable X2
|
|
=
|
Correlation between variable Y with
X2

2). (A Second Order Partial
Correlation)
The second testing correlation is testing correlation between writing
recounts which one of predictor variable that control with two other predictor
variable. So, there are three test in second correlation, they are partial
correlation between writing recount with vocabulary mastery in term of irregular
verb that control simple past tense mastery, partial correlation between
writing recount with simple past tense that control of vocabulary mastery of
irregular verb. The formula are:
3.6.3.3 Multivariate Correlation
Multivariate correlation testing which have
three variables (two predictor and one criterium variable) in order needed the
value
correlation between the three variables and need for
r partial correlation between criterium variable control
and
variables. (Riyanto,2012).The first and the
second partial correlation test have done before, so index correlation data
have got from this count and it can use for count double correlation.
Those data was including in the formula as follow:

CHAPTER I
INTRODUCTION
1.1 Problem
Background
Language is a tool used by humans as the way to communicate or interact. Languages become the
most important in human life. Without language, we will not be able to interact
or relate to other human beings. Own language and characters have different
types, depending on his or her residence. Nevertheless,
judging from its functional all the same language, namely as a means of
communication or interaction.
Many of his countries make
to each other to make a decision, which set one language as a means of international communication. Based on the conclusions of the above, English has been established as a means
of international communication. So those, all country are required to teach English to his people. English skills have four skills,
listening, speaking, reading and writing. And writing is the each one
main aspect of English course, it’s very important for the students. Writing
makes the students are able to write something which related with the students’
minds and it consists of some various genres. And they need to master about
Vocabulary compound words. But, factually some of the senior high school, most
the students finds the difficulties in their own vocabulary mastery. For
example, until this time they are difficult to write something through the
paragraphs, especially to the descriptive text, it happens because the number
of them, they do not master about vocabulary, and get confused about simple
present tense. The students do not understand about descriptive text where as
they try to make it, as the researcher think that vocabulary and simple present
tense mastery are the aspects which very important to make a written through
the text and the students need to master about that all aspects if they want to
write the paragraphs in descriptive text.
From those statements above in this writing
the researcher concludes that before pre-survey at the tenth grade of SMA N1
Seputih Banyak in academic year 2012/2013, and takes focused of the correlation
of simple present tense, vocabulary in term compound words mastery and the
students’ writing ability of descriptive text.

Based on the table above, it can be drawn
that students who got very high score to descriptive text achievement, they
only reached numbers about 5%, high 10%, fair 15%, low 20%, and very low 50%.
The numbers showed percentages of the students’ achievements in descriptive
text is low.
Thus tables drawn in of simple present
tense mastery, compoound words
mastery, and the students’ writing skill of descriptive text, all of the
objects have a correlation to each other which are positive and significant. If
the students are able to master about simple present tense and vocabulary, they
are able to write down sentences through the paragraphs in descriptive text.

CHAPTER II
THEORETICAL FRAMEWORK
2.1
Previous Research Overview
In this
research, the researcher overviews about two previous researches before, they
are:The first one is The Correlation of Students’ Simple Sentence Mastery and
Paragraph Writing Ability at SMK Muhammadiyah 2 Metro, by Nova Cahya Sari. This
research is to know whether there are significant correlation of students’
simple sentence mastery and paragraph writing ability. She was identified some
problems to do this research. There are: 1) students’ ability in writing by
using English language is less. And 2) students’ are difficult to develop their
ideas in form of writing in paragraph. She said that in writing a text we must
be able to use a good language and we also must be able to arrange good
sentence grammatically in order the reader understand about the content of
writing.
The
second previous research is conducted by Siti Karimah, and titled : The Student
Mastery On The Simple presents tense, compound sentences mastery, with their
ability in Writing descriptive Text at The Tenth Grade Of Senior High School
SMA PGRI I Tumijajar 2008/2009”.
The different between those two
previous researches with this research are:
The
first, she did the research to know the student mastery of simple present tense
in writing descriptive paragraph. She has that the students have not understood
the simple present tense perfectly. The students get the difficulty to choose
present from in their writing descriptive paragraph.
The
second, she did the research you know the students teaching learning process in
mastering the simple present tense through descriptive text writing still not
maximum yet because the students have not understood yet the simple present
tense perfectly, they get difficulty in writing descriptive text and get
confused about the structure and grammar.
Followed the
previous research above, the researcher
is interested to do the
research under the tittle the correlation between students’ simple present tense, compound words
mastery and their descriptive
writing paragraph ability at the tenth grade class of SMA N1 Seputih Banyak academic
year 2012/ 2013.
2.2
Theoretical Review
The researcher takes some concepts to support
the research as follows:
2.2.1
Concept of
Simple Present Tense
Simple Present Tense is the most popular
tense in using. According to Azar (2005:60) simple present tense is
generally used to express event or situations that exist, always, usually,
habitually. It means that if we will express situation that exist, always,
usually, habitually we should using the simple present tense. And the simple
present tense is one of tenses which is we should master if we will make a
descriptive paragraph.
Simple present tense has pattren, there
are:
a.
Verbal sentence
Formula :
(+) S + V1 ( s/ es) + O/C
(-) S + do/ does + not + V1 +
O/C
( ?) Do/ does + S + V1 + O/C
(-?) Does / do + S + Not + V1
+ O/C
Example:
(+) My
mother cooks the cake in the kitchen.
( - ) My
mother does not cook the cake in the kitchen.
( ? ) Does
my mother cook the cake in the morning?
Notes : S/ ES : he, she it
Does : he, she, it
Do : they, we, i ,you
b.
Nominal sentence
Formula : (+) S + TOBE ( is, am are) + Adjective/
Adverb
(- ) S
+ TOBE ( is, am are) + not + Adjective/
Adverb
(? ) TOBE ( is, am are) + S +
Adjective/ Adverb
(-?)TOBE ( is, am are) + S +
not + Adjective/ Adverb
Example :
( + ) Justin Bieber is
handsome boy.
( - ) Justin Bieber is not handsome boy.
( ? ) Is Justin Bieber
handsome boy?
Useless of simple present
tense:
Use time signal
a) Adverb of time = put on first or least of
sentence
Every day every / each
Every week in the morning
Every month at sevent
Every year once / twice a day
b) Adverb of frequency = put on after to
belajar or before verb
-
Frequency
adverb follow am, is are:
Always, usually,
often, sometime, seldom, raely, never.
Based on the
data, the simple present tense is used to express daily habit or usually
activities.The simple present tense is also used to express present tense time.
Here, in indicates present time which many non action verb, especially those
expressing state or conditions.
2.2.2
Concept of Compound
Word Mastery
The words in the
English language, especially
adjectives and nouns, can be
combined in a composite construction (compound structures) in various ways. And when combined word is formed, then they have a meaning or meanings of
new words. One sure way to know
the combined words in term compound
words by using a good
English dictionary to find and learn the words of the joint.
There are three
forms of compound words:
1. Closed form(combined words), eg,secondhand, softball, keyboard, notebook, etc.
2. Hyphenated form, for example: his daughter-in-law, master-at-arms, six-pack, etc.
3. Open form(individual words), eg, post office, real estate, middleclass, etc.
Compound words, such as a high school and the peanut butter, as opposed to the wearing of a word or described by adjectives, such as: a little school and the yellow butter. Take a look in the dictionary, compound words always have a special meaning.
The incorporation of the word often uses hyphens (-) to avoid confusion or false meaning, for example: old-furniture salesman, part-time teacher, the highest-priced car, etc. Adverb or adverb sending in-ly do not use a hyphen when combined with other words, for example: a weekly news paper, a highly rated bank, a partially refunded ticket.

Hyphens are also used
to describe a person with age, such as my six-year-old son. However, if the age is placed after the person, then
a hyphen is used: my son is six
years old.
From statement above it can be
confirmed that Compound words are two words that join together and
form a new meaning. But
every word has a meaning that is not far away.
2.2.3 Concept of Writing
Descriptive
Chackraverty and
Guantum (2003) state that “the writing is an important part of language
learning is essentially a reflective activity that requires enough time to think
about the specific topic. The analyze and classify language to structure. This
idea in this view writing is not a product but an activity of a mental process.
The definition
of descriptive text is text with says what a person or a thing is like. Its
purpose is to describe and reveal a particular person, place or thing. It is
clear that descriptive text only shows the fact.
The generics
structures of descriptive text are: identifying the phenomena to be describe,
and describing the phenomenon in parts, qualities and characteristics; the
language features of descriptive text are: using attribute and identifying
process, using adjective and classifiers in nominal group, and using simple
present tense.
It can be
concluded that descriptive text aims at giving vivid details of how something
or someone looks. A descriptive text tells the reader what the thing is, or
what the thing does. A description should be so unique that a description of
one thing should be different from a description another thing. On other words,
descriptive text is not used the generalization. All different, reader should
be able to show the same thing being described in the text. The Lexicon-
grammar text is dominated with simple present tense. This is due to the factual
nature of a descriptive text. The text only shows fact. The clause system is
dominated with relational and material process. Relational process is much
employed do show identification of the thing being describe, while material
process is used to show what the thing does. Because descriptive text show the
attribute of the thing, most clauses us adjective the adjective are mostly
descriptive rather that attitudinal. Descriptive text usually also show part-
whole relationship. When describing a guava tree in front of your house, for
example, the description should cover the description of the whole tree and its
part like the trunk, the branches, leaves and many other parts.
Descriptive
gives sense impressions of the feel, sound, taste, smell and look of thing,
emotion maybe describe too: felling such as happiness, fear, loneliness gloom
and joy. Descriptive helps the reader through his/her imagination, to visualize
a scene or a person, or to understand a sensation or an emotion (Wishon and Burk, 1989:128)
In senior High School
level, the students study about the
purpose, generic structure and language
features of the descriptive text they are:
Purpose: to describe a particular
person, place or thing in detail.
GenericStructure:
1.Identification: identifying the phenomena to be describewith says what a
1.Identification: identifying the phenomena to be describewith says what a
person or a
thing is like.
2.Description: describing the phenomenon in parts, qualities, or/ and
2.Description: describing the phenomenon in parts, qualities, or/ and
characteristics.
3.
Language Features: Using Present Tense
Based on the
statement above, descriptive text is a text which says what a person or things
is like. Its purpose is to describe and reveal a particular person, place, or
thing.
2.3 Thinking Framework
There are 3 variables in this research. They are 2
predictor variables X1 and X2, and criterium variable (Y ). They are as follow:
2.3.1
The Correlation of Simple Present Tense, Compound Words Mastery and the Students’ Writing ability of Descriptive text
Writing skill is one of fourth skill in learning language. They are
listening, speaking, reading and writing. Writing skill is the most difficult
skill between the others. Because in writing, the students should not only
learn the vocabularies and structure, but they should understand the way to
express their idea. In writing, the readers are not faced with the writer
directly therefore, the writer has to communicate the message clearly.
The teaching
writing, especially in descriptive paragraph often makes the students feel so
difficult because they do not master both tenses which uses on it there are simple present tense and vocabulary
in term compound words and it causes them difficult to express their idea. In
this case, the teacher should use the better technique to increase students’ simple present tense.

Hypothesis
Based on the theories, the researcher formulated the hypothesis as
follows:
1)
There are positive and significant correlation between students’ simple present tense
mastery and the students’ writing ability of descriptive text
2)
There are positive and significant correlation between
Compound words mastery and the students’ writing ability of descriptive text
3)
There are positive and significant a correlation of students’ simple present
tense,
Compound words mastery and the students’ writing
ability
of descriptive text simultaneously.
CHAPTER III
RESEARCH METHOD
3.1
Research Design
In
this research the researcher
used this is quantitative research used correlation study. That is one of ex
post facto design. Correlation study here means that the writer used one group
to be tested and takes the data without giving any treatment. The researcher
uses this design because he tried to find out the direct relationship between
the predictor and criterium variables from a group of
students who give the data on two different variables without giving any
treatment or control.
This
research, the researcher used
tests to get the data of simple present tense mastery,compound words mastery and the students’ ability
in writing descriptive. After getting the data, the researcher analyzed it and then gave the
description whether there is a significant correlation of simple present tense
mastery (X1), compound words (X2),as the predictor and the students’ ability in writing descriptive(Y) as the criterium variable.
The Design of this research is:
T1 T2 T3
( Hattach and Faradhy, 1982:
P.27 )
à Test 1 x1® y
à Test 2 x2® y
à Test 3 x1® x2 ®
y
Note:
Test
1 : Test simple present tense mastery
Test
2 : Test vocabulary mastery
Test
3 : Test writing descriptive
It means, in doing the
research, the researcher will use test of simple present tense mastery (T1
), compound words
mastery (T2) and
then it is continued by test of writing descriptive (T3). The tests
are proposed to find out the students' simple present tense mastery, compound
words mastery and the students’ ability in
writing descriptive. The researcher did not give the third test for the
students who got low score. The researcher hopes after conducting those tests.
The students will know the level of their simple present tense mastery, compound
words mastery and the students’ ability in
writing descriptive especially for the students who have low ability in simple
present tense mastery, compound words mastery in
the students’ ability in writing descriptive.
3.2
Research Variable
The researcher has determined
three variables of the research that while is investigated, they are:
1)
The criterium variable of this is the students
ability in writing descriptive that is symbolized by ( y );
2)
The predictor variable of this research is the
students simple present tense mastery that is symbolized by ( X1 );
3)
The predictor variable of this research is the
students’ compound words mastery that is symbolized by (X2).
3.2.1 Conceptual Definition of the
Students’ Mastery in Simple Present Tense
The simple
present tense is used to express daily habit or usually activities. The simple
present tense is also used to express present tense time. Here, in indicates
present time which many non action verb, especially those expressing state or
conditions.
3.2.2 Operational Definition of the Students’
Mastery in Simple Present Tense
In
simple present tense test which consists of 40 items. This test is multiple
choices which consist of four options (A, B, C, and D). This test used to the
students’ simple present tense mastery.
3.2.3
Conceptual
Definition of the Students Compound Words mastery
Compound words are
two words that join together and form a new meaning.
But every word has a meaning that is not far away.
3.2.4
Operational Definition of the Students Compound Words Mastery
In
vocabulary in term compound words test which consists of 40 items. This test is
cross-puzzle and essay. This test used to the students’ vocabulary mastery in
term compound words.
3.2.5 Conceptual Definition of the
Student’s Their Ability in Descriptive Text
Descriptive text
is a text which says what a person or things is like. Its purpose is to
describe and reveal a particular person, place, or thing.
3.2.6 Operational Definition of the Students’Their
Ability in Discriptive Text
In the writing
paragraph test, the researcher would like give essay test. The students must
make a paragraph consist of 200 words. The topic of it is “Free”. This test
used to know, how far the students’ can make in paragraph writing well
according their ideas.
3.3
Research Population, Sampling Technique and
Sample
3.3.1
Population
The
population of this research is the grade tenth of SMA N1 Seputih Banyak which
consists of two classes. There are X1, X2, X3, and X4. Total sum of the whole students of grade tenth is 100 students.
3.3.2 Sampling
Technique
The
researcher takes randomly sampling. To get sampling from researcher population,
the researcher does some steps as follows:
1.

2.
Write the classes in piece of paper
3.
The paper wrapped and then put into a jar
4.
Then, there is a little slit on the jar’s mouth to let
one piece wrapped out
5.
The paper which comes out firstly is as the sample of
this research.
3.3.3

The Validity
3.4.2.1.1 The Validity of Vocabulary Mastery and
Simple present Tense
Mastery
To
get the validity of the test the researcher uses internal validity. Validity is
a standard or criterion that shows the instrument is valid or not. A test is
valid to extent that is measures what it claims to measure (Arikunto,
1985:145). To calculate the validity of each item the writer used the product
moment formula:
Where:
Rxy = coefficient of
correlation between x and y variable or validity of each item.
N = the number of
students/subject participating in the test.
∑x = the sum of score in each item.
∑x2 = the sum of the square score in each
item.
∑y = the sum of total score each students.
∑y2 = the sum of square total score from each
students.
∑xy = the sum of multiple of score from each
student with the total score in
each item.
3.4.2.1.2
The Validity
of Students’ Ability in Writing Descriptive
The researcher
was using essay writing as the test to number about the students’ skill in
descriptive text. They have to write something through the paragraphs as the
criteria in descriptive text which consisted of the main contents are
orientation, even and re-orientation, and about generic structure in
descriptive text. Every paragraph had point if all the paragraphs were great,
and the students would get 100 score.
3.4.2.2 The Reliability
3.4.2.2.1
The Reliability of
Vocabulary Mastery in term of Compound
Words and Simple
Present Tense Mastery
The test can be said reliability if the test has been given in
some place but the result of the test is the same with another place. To know
the reliability of the test, the researcher will employ the formulation alpha
of Arikunto (2006:196), as follow:
Note:
= Coefficient correlation regularity level
(reliability)
n =
Number of items.
= Total score of each item
= Total Variant
For finding the Variant formula, the researcher will use the
formula below:
Note:
= Total variant
= Total items which are
quadrate
= The total sum of the quadrate
items
= The number of
items
The other words then from calculation result of interpreting the
coefficient correlation according to Arikunto (2006:276) as follows:
Between 0.800 – 1.000
very high
Between 0.600 – 0.800
enough
Between 0.400 – 0.600
fair
3.4.2.2.2 The
Reliability of Students’ Ability in Writing Descriptive
To know whole
reliability of descriptive writing of diary the researcher will use inters
rater to give the score of students’ work. There is another rater who give
score the students’ work. The score of Students work are divided by two. The Researcher also use single test single trial method to know
the reliability of descriptive writing test. The formula will use to correlate
the result is HJ X Fernandes cited in Arikunto (2006:201) formula as follow:
Description:
K : Coefficient of
agreement
S : agreed, the same code
for the same object
N1 : Number of
code that made the rater I
N2 : Number of
code that made the rater II
After going through several procedures, the formula is further
refined, known as Rough Suitability Index (CCI) with as the same code, and N is
the number of objects being observed. The smaller the value of KK is a list of
checks or instruments of observation are more reliable.
3.5
The Data Collecting Technique
The data collecting for this research is gained from the student test result. The
tests are intended to measure the students achievement in students
mastery of simple present tense,
vocabulary in term compound wordsand their ability in descriptive text to express their part
activities in writing.The prosedure
of tests are as follow:
Test to measure student’s
achievement in vocabulary the kinds of the test administrated is essay,
students’ mastery of simple present tense the kind of test administrated is multiple choice, in which the students are aksed to
choose the correct one of four options offered of each question.
The students
would get the highest score if they could write the right descriptive text which shoud be consisted with the
criteria as follows:
-
Identification
-
Description
-
Language Features
The classes of those above scoring criteria in descriptive, they have some categories.
Adaptedto Tribble’s statement and He
says that “in scoring the students’ writing ability, the researcher used
analytic rating scale. He describes thus classes ofcriteria throughout the table which it can be seen at appendix 6, and testing for this writing descriptive text it applies at appendix 3.
3.6
Data Analysis Technique
In
analysis the data, the writer will use the descriptive qualitative research.
The data is taking from the student’s mastery in simple present tense and the
student’s their ability descriptive text test. Then, the result of scoring of
both the researcher and the other were added and divided by two. After the
researcher giving the test and finding the result of the test will be taken by
using normality test and homogeneity test.
3.6.1 Normality test
In this research, to
meansure normality test is used the formula as follows:
Ho : Data normality distributed
Ha : Data abnormally distributed
Normality test used
is Kolmogrov (mirnov test in kolmogrov s mirnov test assusmes that variable
distribution has continue, the formula is as follows :
D
= max
Where:
Fo(X1)
: Distribution function of cumulative frequency from theoretic in Ho
condition
Sn (Xi)
: Distribution function of cumulative frequency from observation as many
as n.
By comparing D toward D kolmogrovsmirnov with
significant level X
If D<D table so reject Ho and if D>D
table so accept Ho
The decision is also can take based on
significant score if the significant score < X so reject Ho So also in the
control
·
Reject Ho if significant score less than ( <
) 0, or it means the distribution of data is not normal.
·
Accept Ho if significant score more than ( >
) 0, or H means the distribution data is normal.
3.6.2
Homogeneity
test
The
objective of homogeneity test is to know whether the sample is taken from
homogeny Varian population or not.
Homogeneity
is tasted by using one way ANOVA,
The
formula is as follows:
Zit = Yit –Yi
Where:
Yit : the
sample score in every variable
Yi : the
main of sample
With
critical value F (α, k-1, n-k)
Criteria :
·
If probability (sig) more than ( > ) 0,05 Ho
is accepted;
·
If probability (sig) more than ( < ) 0,05 Ho
is receipted;
3.6.3 Correlation Test
Correlation test usually used to search a correlation
and direction of correlation between groups of data. Correlation coefficients
has a value between -1 until 1, if coefficient value of correlation approach
absolute value 1, showing that there is a strong correlation between both of
variable that correlated. But, if coefficient value of correlation more and
more approach 0 that means show that there is a correlation which not linier.

Commonly, known that are two kind of correlation
namely; bivariate correlation is a correlation model that used just for know
about the correlation between both of variables. And then, partial correlation
is a correlations model that used to condition when measure of correlation
between two variable.
3.6.3.1
Bivariat Correlation
Hipotesis
test used correlation technique. Correlation test between or variable and
predictor variable and criterium variable (Y, X1), (Y, X2), or between
predictor variable (X1, X2) are counting used the correlation formula is
product moment because the result of data is interval data. The formula is :
rxy =
There are ranges of correlation value based on Young:
·
0, 7 – 1, 00 positive or negative, showing of
high degree of correlation.
·
0, 4 – 0, 7 positive or negative, showing of
substantial degree of correlation.
·
0, 2 – 0, 4 positive or negative, showing of low
degree of correlation.
·
<0, 2 positive or negative, showing of
ignored correlation.

Soenyono, 2007: 109),
3.6.3.2 Partial Correlation
1). (A First Order Partial
Correlation)
Parsial correlation test is the first step
correlation test between one predictor
variable with criterium variable that control with other predictor
variable. This testing used to getting correlation index number which not iffected other variables.
This testing used to get index number and will using to count double
correlation. The formula is:
Description
|
=
|
Correlation between variable Y (criterium) with of variable X1 (predictor) with
controlled by variable X2
|
|
=
|
Correlation between variable Y with
X2
|
|
=
|
Correlation variable X1 with
X2
|
Description
|
=
|
Correlation between variable Y (criterium) with of variable X1 (predictor) with
controlled by variable X2
|
|
=
|
Correlation between variable Y with
X2
|
|
=
|
Correlation variable X1 with
X2
|
2). (A Second Order Partial
Correlation)
The second testing correlation is testing correlation between writing
recounts which one of predictor variable that control with two other predictor
variable. So, there are three test in second correlation, they are partial
correlation between writing recount with vocabulary mastery in term of irregular
verb that control simple past tense mastery, partial correlation between
writing recount with simple past tense that control of vocabulary mastery of
irregular verb. The formula are:
3.6.3.3 Multivariate Correlation
Multivariate correlation testing which have
three variables (two predictor and one criterium variable) in order needed the
value
correlation between the three variables and need for
r partial correlation between criterium variable control
and
variables. (Riyanto,2012).The first and the
second partial correlation test have done before, so index correlation data
have got from this count and it can use for count double correlation.
Those data was including in the formula as follow:
Note:
ry-123= correlation between Y with predictor
