PROBLEM STATEMENT

1.

Is Cooperative Learning more effective than Audiolingual Method to teach Speaking Skill?

2.

Do the students taught by using Cooperative Learning have significant improvement in speaking skill?

3.

Do the students taught by using Audiolingual Method have significant improvement in speaking skill?

OBJECTIVE OF THE RESEARCH

This research is aimed at discovering whether: 1.

Cooperative Learning is more effective than Audiolingual Method to teach Speaking Skill.

2.

The students taught by using Cooperative Learning have significant improvement in speaking skill.

3.

The students taught by using Audiolingual Method have significant improvement in speaking skill.

RATIONALE

1. The difference between Cooperative Learning and Audiolingual Method ..... The nature and characteristics of CL in teaching speaking.....

..... The nature and characteristics of AM in teaching speaking.....

So it is predicted that Cooperative Learning is more effective than Audiolingual Method.

2. The significance of Cooperative Learning in teaching speaking.

..... the importance of CL in teaching speaking .....

..... the role of CL in teaching speaking .....

So it is believed that the students taught by using Cooperative Learning have significant improvement in speaking skill.

3. The significance of Audiolingual Method in teaching speaking.

..... the importance of AM in teaching speaking .....

..... the role of AM in teaching speaking ....

So it is assumed that the students taught by using Audiolingual Method have significant improvement in speaking skill.

HYPOTHESIS

1.

Cooperative Learning is more effective than Audiolingual Method to teach Speaking Skill.

2.

The students taught by using Cooperative Learning have significant improvement in speaking skill.

3.

The students taught by using Audiolingual Method have significant improvement in speaking skill.

RESEARCH METHOD

 The

aim of experimental research

between variables. is to establish cause-and-effect relationships  The

Independent Variable

changes in the many other factors.

causes the

Dependent Variable

. The changes or effects may be influenced by  The purpose of experimental designs, therefore, is to eliminate the intervening factors, so that the Independent Variable is really the cause.

Independent variable

 The variable the researcher manipulates  The cause for the difference  The treatment is given to

Dependent variable

 The skill, knowledge, or attitudes which may have changed due to the experiment  That which depends on the independent variable  Must be measurable

Three Characteristics of an Experiment

Three characteristics of an experimental research: (1) there is manipulation or treatment to the independent variable, (2) (3) other extraneous variables are controlled observing the effect of the independent variable treatment on the dependent variable.

RESEARCH DESIGN

 There are three variables: one dependent variable (Speaking Skill) and two indepen dent variables (Cooperative Learning and Audiolingual Method).

 The research design used in this experimental research is Pretest-Posttest Nonequivalent Groups Quasi-Experiment .

Types of Designs

Type 1

Posttest Only Randomized Experiment

R X O R O

R = RANDOMIZED X = TREATMENT O = POSTTEST

Type 2

Pretest-Posttest Randomized Experiment

R O1 X O2 R O1 O2

R = RANDOMIZED X = TREATMENT O1 = PRETEST O2 = POSTTEST

Type 3

Pretest-Posttest Nonequivalent Groups Quasi-Experiment

N O1 X O2 N O1 O2

N = Nonequivalent X = TREATMENT O1 = PRETEST O2 = POSTTEST

Type 4

Pretest-Posttest Non Experiment

O1 X O2

X = TREATMENT O1 = PRETEST O2 = POSTTEST

DATA COLLECTION

Penelitian eksperimental dengan mengguna kan design

Pretest-Posttest Nonequivalent

Groups Quasi-Experiment, data yang dikumpulkan adalah hanya satu jenis data yaitu data untuk Speaking Skill.

Instrumen

yang digunakan adalah TEST, yakni berupa Speaking Performance Test. SpeakingTest diadakan dua kali yaitu sebelum tindakan

(Pre Test)

dan sesudah tindakan

(Post Test).

Data yang telah terkumpul (berupa rekaman) dinilai berdasarkan

Hypothesis Testing

1. Hipotesis 1: Pertama, menggunakan Independent t-Test untuk mengetahui perbedaan prestasi antara kelompok E dan C signifikan atau tidak. Kedua, setelah terbukti berbeda secara signifikan, mean score dari kelompok E dan C dibandingkan, dan kelompok yang memiliki mean score lebih tinggi berarti teknik mengajar yang digunakan lebih efektif.

2. Hipotesis 2: Pertama, menggunakan Non- Independent t-Test untuk mengetahui perbedaan prestasi antara Pretest dan Posttest signifikan atau tidak. Kedua, setelah terbukti berbeda secara signifikan, mean score dari Pretest dan Posttest dibandingkan, dan bilamana Posttest memiliki mean score lebih tinggi berarti siswa yang diajar dengan Cooperative Learning mengalami kemajuan berbicara (Speaking Skill) yang signifikan.

3. Hipotesis 3: Pertama, menggunakan Non- Independent t-Test untuk mengetahui perbedaan prestasi antara Pretest dan Posttest signifikan atau tidak. Kedua, setelah terbukti berbeda secara signifikan, mean score dari Pretest dan Posttest dibandingkan, dan bilamana Posttest memiliki mean score lebih tinggi berarti siswa yang diajar dengan Audiolingual Method mengalami kemajuan berbicara (Speaking Skill) yang signifikan.
