ABSTRACK:The technique of collecting data was by using a test. After the data
of the effectiveness of cooperative learning and to improve students speaking
communicative skills were collected, the data were statistically computed to find
out the correlation between the two varibales. The writer analyzes the data based
on the effectiveness of cooperative learning to improve students speaking
communicative skills. This data is analyzed by using correlation product moment.
The value of correlation coefficient obtained is 0,544, while the criteria of the
correlation between 0,40 to 0,70 are considered moderate. It means that the level
of relationship of the correlation coefficient of the two variables is moderate. In
this research the variable Y is influenced too high by the variable X and the other
way the varble is also influenced too high by the variable Y. For the contribution
variable X to Variable Y, the writer get influence 29,60 % applying the
effectiveness of cooperative learning to improve students speaking
communicative skills and 70,4 % left is influenced by other factor, it means that
the effectiveness of cooperative learning to improve students speaking
communicative skills at grade VII of SMP PGRI 174 Cikupa Tangerang has quite
influence.
Keyword: EFFECTIVENESS OF COOPERATIVE LEARNING, STUDENTS
SPEAKING
1. INTRODUCTION
The learning process in the Education Unit Level Curriculum (KTSP) requires the
active participation of all students. Thus, student centered learning activities, the
teacher as a motivator and facilitator in it for the class more attractive atmosphere.
Jigsaw cooperative learning techniques are considered particularly suitable to be
applied in education in Indonesia, especially for Junior High school students
because of them in accordance with national culture that values mutual
cooperation.
Based on the above information, the researcher is interested to Cooperative
Learning , because It is a kind of activity guided by the aim or purpose to be
accomplished, which suggests a change from the traditional teacher centered
teaching method to a focus on learner centered learning. Some believe that the
traditional teaching methods only stress theoretical content and neglect training of
any skills involving effective interaction between both teacher-student and
student-student in the EFL (English as Foreign Language) classroom, while
1

cooperative learning will improve students’ confidence in using a foreign
language and as lingua franca, encourage students in creative thinking and active
learning, and help students gain English speaking skills intuitively. Others argue,
however, that the cooperative learning method has some limitations related to our
current junior high school students situations such as too many students in one
class, uneven development across speaking, and a tradition of task-aimed teaching
methods. The cooperative learning method has gained a considerable reputation in
English as a foreign language learning classrooms or a second language
classrooms all over the world. Meanwhile, it is also very important for people to
enhance cooperation with others to improve speed and success levels for assigned
tasks. These address social needs and academic needs for students. However, the
results of students’ English proficiency, especially in English speaking skills, have
not improved satisfactorily even after more than ten years of formal instructions.
Students who demonstrate sub-standard English speaking performance are
troubling since speaking skill is central to learning process and academic
achievement in other content areas. Therefore, the purpose of this research paper
is to determine whether or not cooperative learning has a positive effectiveness on
speaking skills. A related purpose is to discover the limitations of cooperative
learning to be carried out in Indonesia and to make some recommendations to
resolve these problems.
Therefore, a researcher is being challenged to help student’s problems to
conduct research and get best solutions for improving speaking skills. The
treatments which are given some steps to the students, such as; first, acknowledge
thoughts ideas or feelings, second, Say it different words, forth, Ask and open –
ended question, fifth, Summarize and clarify , the last ,Give opinions. It can make
them widely insight into the understanding of speaking skills, give high
motivation for speaking that they will not get failure but get good experience,
recognize about some good learning strategies, enrich new vocabularies which
make easier to speak or describe something, make discussion about some
interesting topics in the text from simple topic until difficult topic which
The objective of this research, she wants to understand about students’
difficulties of SMP PGRI 174 Tangerang - Banten communicative Speaking skills
, and giving a solution toward learning process by changing from old style to
newest style which is better, namely the usage of cooperative learning more
effective to conduct student’s achievement of speaking skills. Given the
restrictions on the issue, the study aims to answer the following questions : Is
there any effectiveness of Cooperative Learning to improve student’s
communicative speaking skills at first grade of SMP PGRI 174 Tangerang-
Banten ?
2. THEORITICAL FRAMEWORK
2.1.Cooperative Learning
Cooperative learning is one strategy for group instruction which is under the
learner-centre approach. Many educators give the definitions of cooperative
learning.
3
It is supported by Brown (1994) said that : “Cooperative learning involves
students working together in pairs or groups, and they share information .They are
a team whose players must work together in order to achieve goals successfully.”
In addition, Kessler (1992) proposes the definition of cooperative learning
particularly in language learning context: “Cooperative learning is a within-class
grouping of students usually of differing levels of second language proficiency,
who learn to work together on specific tasks or projects in such a way that all
students in the group benefit from the interactive experience.”
2.2. The Definition Of Speaking Skills
Tarigan, (1987:15) said that: Speaking is the ability to utter articulate sounds or
words to express, express and communicate thoughts, ideas, and feelings. The main
purpose of speaking is to communicate. Communication can unite individuals into
groups by way convey the general concepts, creating a unity of symbols that
distinguish it from other groups, and assign an action, and will not survive long if
not societies language.
Speaking language is a skill that develops in the child's life, which only
preceded by listening skills, and on the ability to speak or say. It was studied
Tarigan, (1981:3).
2.3. FRAME OF THINKING
Cooperative learning is a teaching method that creates a feeling of togetherness
and confidence of the students to improve their ability to speak in class, so Gagne
describes learning as, a set of external events for the scholarships that are
designed to support internal learning processes.in the context of learning and the
impact on student learning outcomes, because learning is a process performed by
an individual over time everywhere. Thus, learning is a process that involves the
selection, arrangement, and delivery of appropriatemess ages to the environment
and how learners interact with information them.
The effects of cooperative learning, in some ways, may be intangible and
cannot be quantitatively assessed with accuracy. However, research has suggested
that cooperative learning is a better way to promote academic achievement than
traditional instruction. In a study conducted by Stevens and Slavin (1995) students
who had participated in cooperative learning were post-tested two years after
initial training. These students scored significantly higher on academic tasks than
students involved in traditional classroom instruction. (Lopata, 1-2), Interaction
between group members implies that students gain approximately five times more
input concerning the content than students engaged in individualized tasks. This
results in more relevant information, as well as improved language expression.
(Gillies, 1-2) The academic benefits make cooperative learning a highly desirable
asset in the education society.
Within special education and remedial classrooms, cooperative learning
has promoted interaction, as well as emphasized the value of cooperation, among
group members (both preferred and non-preferred). However, modifications and
accommodations may be more necessary in these classrooms. The most dominant
modification needed is in the selection of group members. (Jenkins, 16) Another
4
noteworthy benefit of cooperative learning is the inclusion of students with
exceptionalities and learning differences into regular classrooms. (Gillies, 1) In
one study, the most common benefits mentioned by special education teachers
implementing cooperative learning were "self-esteem, the security that comes
from being part of a group, and higher success rates and/or better products."
(Jenkins, 7) Group relations -- an obvious element of cooperative learning -- can
be used to bridge the gap between ethnic and race groups in society beginning in
the classroom.
"The challenge for educators is to create the conditions under which
students are likely to cross the borders that delimit their narrow personal and
social worlds and provide opportunities to experience the worlds of those
different from them. Positive cross-ethnic interactions help students expand their
own self-identity and build an appreciation of difference at the same time."
(Cooper, 1)
2.4. HYPOTHESIS
Null Hypothesis (Ho) : There is no effect of Cooperative Learning to
improve communicative speaking skills at grade
VII of SMP PGRI 174 CikupaTangerang.
Alternative Hypothesis ( Ha) : There is any effect of Cooperative Learning to
improve communicative speaking skills at first
grade of SMP PGRI 174 Tangerang- Banten.
3. RESEARCH METHODOLOGY
3.1 Population and Sample
a. Population
The writer will analyze the seventh grade of Junior High School at SMP PGRI
174. There are 100 students of seventh grade, which consists of 68 females and
32 males.
b. Sample
The writer takes 30 students as sample from the seventh grade of SMP PGRI 174
Cikupa Tangerang using prefer ship random sampling technique considering the
high of homogeneity. According to Suharsimi if the subject of the research is
between a hundred population or more, we can take those subjects between 10 %
until 15 % or more from the population as random sampling. So the percentage of
this sample in this research is 25 %. It means that the sample is quite
representative.
3.2 Method of The Research
In conducting the research, the writer use correlation method (Tx Ty). She
applies Cooperative Learning and Speaking skills test to investigate student’s
cooperative learning and their speaking skills test. then she formulates the score
by Pearson Product Moment formula to find out the correlation coefficient value.
The writer use quantitative research. Quantitative research is to develop
and mathematical models, theories and / or hypotheses pertaining to phenomena.
5
3.3 Validity and Reliability
In order to gain trustworthy data, the instruments that will be used within a
research should be reassured for its validity and reliability. Since the researcher
will use Strategy Inventory for Language Learning (SILL) developed by Oxford
(1989) in this study , the researcher will not test the validity and reliability of this
questionnaire due to it was already known for its validity and reliability , and for
the reason within this discussion, the researcher only will reassure the validity and
reliability of speaking skills test that will be used in this study.
a. Validity
Gronlud (1988) in Brown said that validity refers to “the extent to which
inferences made from assessment results are appropriate, meaningful, and useful
in terms of the purpose of the assessment”. Thus, a reading test can only be said
valid if it actually measures reading ability .moreover, Alderson (1995) cited in
Arifin states :
A good test has three criteria, namely; rational, empirical and construct
validity. Rational (content) depends on a logical analysis of the test content to see
whether the test contains a representative sample of the relevant language skills,
empirical validation depends on empirical and statistical evidence as to whether
students marks on the test similar to their scores on other test, their assessment of
their teacher’s ratings of their ability. Construct validation refers to what the test
scores actually mean.
b. The Reliability
On the other hand, a test is considered to be reliable when the scores of the test are
consistent. Haris said that “ a test cannot measure anything well unless it measures
consistently”. According to Henning (1987) there are two conditions where we
can say an instrument is reliable without the need to be tried out. First, the
instructions of the instrument should be made clear to be understood by
respondents, that is, by making them short and precise. In this case , the language
used in the instrument should be relevant to the level of the students. Second, the
instrument should be arranged to avoid “ a tendency on the part of the respondents
to inflate positive evaluations by consistency and arbitrarily giving high ratings.”
Another way to obtain the reliability ,without the necessity to conduct a try
out test is by using the method of Split half reliability . according to the Split Half
method (Henning),the test is administered once half contains the odd numbers and
the other contains the even numbers.the scores of each half are then correlated
without the other half.To measure coefficient of the reliability of the first and
second half groups, the researcher will use the following formula :
6
note :
r : the correlation /coefficient of reliability of the score from one
half of the test with those from the other half
X : the total numbers of the first half group
Y : the total number of second half group
The criteria can be seen below.
Table.3.1 Criteria for Reliability Index
The Mount Of Rxy Interpretation
0.00 – 0.20 Very low
0.20 – 0.40 Low reliability
0.40 – 0.70 Medium reliability
0.70 – 0.90 High reliability
0.90 – 1.00 Very high reliability
3.4 Technique of Data Collecting
In completing the data, the next step of this research is collecting the data; the
function of data collecting is to determine the result of the research.
In collecting data, the writer uses some techniques.
a. Observation
The first is by observing directly to the location where the research is carried out.
The purpose is to ask permission from the headmaster, getting important
information from the English teacher about his teaching materials and the uses of
their curriculum.
b. Testing
Since the writer wanted to investigate the correlation between two kinds test,
Cooperative Learning and Speaking skills ,so that the writer use test method. The
test is divide into two parts, the first is Cooperative Learning, the second is
Speaking skills.
c. Research procedure.
To collect the data, the researcher will use the speaking test and 2 (two)
questionnaires. There are several steps that will be done in gaining dat. First, the
researcher will explain the purpose of conducting the research to the participants
and inform them that they have to do a speaking test and answer the
questionnaires regarding their general information and the cooperative learning
that they will be using. Second , the researcher will administrate the speaking test
and supervise it. However, before the test should be completed in 60 minutes. At
last, the questionnaires will be given to the students to be filled in after they will
accomplish the test. The result of the speaking test and the questionnaires will be
scored based on scales mention previously.

4.3. Hypothesis Testing
Provide interpretation of rxy and draw conclusions after the unknown value of “r”
(r the calculation), then authors interpret the results of these calculations are: Hn is
accepted if the price of “r” (r the calculation) is less than the price of “r” table.
Conversely, if the price of “r” than or equal to the price of “r” table, so Ho
accepted.
To determine the level of correlation (correlation criterion) of the “r” (result of
calculation between the tow varibles, it consulted with the criteria of “r” product
moment. The criteria are:
Less than 0.00 – 0.20 : the correlation is very less it is urgently ignored.
Between 0.20 – 0.40 : the correlation is low
Between 0.40 – 0.70 : the correlation is low but significant
Between 0.70 – 0.90 : the correlation is high
Between 0.90 – 1.00 : the correlation is very high
13
From research and data processing or analysis, the authors provide data
interpretation of rxy.
From the calculation of “r” (“r” calculation) = 0,544 and the result is meaned the
correlation is low but significaly. This means that there is considerable
cooperative learning to improve student speaking communicative skills is
sufficient correlation.
Thus, the results of a study of “r” calculation is sufficient the effectiveness of
cooperative learning to improve student speaking communicative skills in the
school SMP PGRI 174 Cikupa Tangerang.
Likewise, if the price were consulted “r” calculation (0.544) into the product
moment coefficient of criteria (interia for reliability index p.39 ) which lies
between 0.40 – 0.70, indicating sufficient correlation criteria.
To know the sigificane index price significant influence on a certain level, we
need to hold the testing of hypotheses. Testing is done by comparing the size of
“r” calculated by the “r” listed in the table “r” product moment by first seeking the
degree of free (db) or its degrees of freedom (df) that the formula as follows:
df = N – nr
description of the formula
df = degrees of freedom
N = Number of cases
n r = number of variables
By obtaining degrees of freedom, then it can look for the “r” listed in the table of
values “r” product moment, both at significant level 5% and the level 1%. In this
case degrees of freedom are:
df = 30 – 2 = 28
for in this table are the number 28, then its value at df = 28 with 5% significance
level obtained pricing table r = 0.374. Thus, “r” the calculation (0.544) is greater
than “r” table, 0.544 > 0.374, then at 5% significance level the null hypothesis
(Ho) is accepted.
Then, when compared with the “r” calculated with the “r” table at 1% significance
level where the “r” in the table with df = 28 is 0.478, then at any significant level
of 1% “r” calculation is smaller than “r” tables, 0.544 > 0.478, so the null
hypothesis (Ho) is rejected.
Thus, the results of a study of “r” calculation is effectiveness cooperative learning
to improve student speaking communicative skills in the school SMP PGRI 174
Cikupa Tangerang. At the 5% significance level but not at significant level 1%.
Determine how big the contribution variable X to variable Y by using coefficient
determination:
CD = r2 x 100
= (0.544)2 x 100
= 0,295936 X 100
= 29,5936 = 29,60
From the last calculation we get the effectiveness of cooperative learning 29,60%
(Variable X) to improve student speaking communicative skills (Varible Y). while
14
70,4% left is influenced by other factors that it can be reexamined. It means that
the effectiveness cooperative learning to improve student speaking
communicative skills in the school SMP PGRI 174 Cikupa Tangerang has quite
influence.

5. CONCLUSION AND SUGGESTON
5.1.Conclusions
After conducting the research, the writer comes to her conclusions that:
1. From the calculation of “r” calculated = 0.544 and the price is marked
positive correlation coefficient. This means that the effectivess of cooperative
learning to improve student speaking communicative skills in the school SMP
PGRI 174 Cikupa Tangerang is direct correlation to moderate. From the
results of a study of “r” calculated at significance level of 5% and 1%.
Likewise, if consulted “r” 0.544 calculation into the product moment
coefficient of criteria which lies between 0.40 to 0.70, indicating sufficient
correlation criteria.
15
2. So it can be seen how the value of “r” and how many degrees of free. At df \
28 with 5% significance level obtained pricing table r = 0.374. Thus, “r” the
calculation (0.544) is greater than “r” table, 0.544 > 0.374, then the
significance level of 5% of alternative hypothesis (Ha) accepted. This means
at the 5% significance level there is a effectiveness between motivation in the
school environment and academic achievement that was achieved.
3. Then, when compared with the “r” calculated with the “r” table at 1%
significance level where the “r” in the table with df = 28 is 0.478, then at any
significant level of 1% “r” calculation is greater than “r” tables, ie, 0.544 >
0,478, so the null hypothesis (Ho) is rejected any significant level of 1% “r”
calculation is greater than “r” tables, ie, 0,544 > 0,478, so the null hypothesis
(Ho) is rejected.
5.2. Suggestion
