1 EXPERIMENTAL RESEARCH Created by: Armayani Idrus Ria Helmaliza Wilda Maysari

2 DEFINISI Penelitian Eksperimen adalah: sebuah penelitian yang bertujuan untuk menyelediki hubungan sebab akibat dengan cara membandingkan kelompok eksperimen dan kelompok kontrol.

3 A DA DUA KELAS DALAM PENELITIAN EKSPERIMEN : 1. Kelas Eksperimen (Experiment Class) - Mendapatkan treatment (perlakuan) 2. Kelas Kontrol (Control Class): - Tidak mendapat treatment - Sebagai pembanding

4 KARAKTERISTIK: 1. Kontrol 2. Manipulasi variabel independen 3. Observasi

5 VALIDITAS EKSPERIMEN 1. Validitas Internal ( Internal Validity ) 2. Validitas Eksternal ( External Validity )

6 JENIS PENELITIAN EKSPERIMEN 1. True Experimental (murni) 2. Quasi Experimental (semu) 3. Single Subject

19 CHAPTER I INTRODUCTION A. B ACKGROUND O F T HE PROBLEM Language is a systematic means of the communication by the use of sounds or conventional symbols. It is the code that we use to express ourselves and communicate to others.

Individualistic Learning exists when the learning or achievement of one students is independent and separate from…. 3. Collaborative Learning takes place when student…. 4. Cooperative Learning occurs when students work collaboratively…..

24 D. F ORMULATION O F T HE P ROBLEM Is there any significant difference between learning motivation of students who are taught using cooperative learning and those who are taught without it?

25 E. O BJECTIVES O F T HE R ESEARCH To find out whether there is any significant difference between learning motivation of students who are taught by applying Cooperative Learning and those who are taught without it.

26 F. S IGNIFICANCE O F T HE R ESEACRH 1).For the teacher, it can be useful information about the effectiveness……… 2).The school can see how far Cooperative Learning influences………. 3).The significance for English Education Department of Yogyakarta State University is enriching and enlarging………….

30 CHAPTER III RESEARCH METHOD A. R ESEARCH T YPE This research is a quantitative research. This study can be classified into a quasi-experimental study. The design used is an in tack group pretest- posttest design that involves a group of students who belong to the experimental group and the one belong to control group. In this study, the treatment, which is given, is applying cooperative learning in teaching learning process.

31 B. V ARIABLES O F T HE S TUDY The independent variable of this study is cooperative learning. X, represents this variable. The dependent variable is students’ motivation, which is represented by Y. The design of the research can be shown in this table: GROUPINDEPENDENTDEPENDENT ExperimentXY ControlXY

32 C. R ESEARCH P OPULATION AND DESIGN The population on this study is two classes of the 2 nd grade students of SMA Negeri 1 Kebumen of Academic Year. NOCLASS CLASSIFICATION (GROUP) NUMBER OF STUDENTS 1A140 students 2A240 students

33 The selection group for the experiment and non-experiment (control group) will use coin toss. The experiment group will be given cooperative learning activities and no treatment for the second group. Here is the distribution of treatment in the research.

34 D. R ESEARCH I NSTRUMENT 1. Instrument of the research This study will use questionnaire as the instrument of the research to gain data to see the significant result of students’ motivation. 2. Validity of the instrument To see the validity of the instrument, the researcher uses Product Moment Correlation formula. 3. Reliability of the instrument The researcher uses Alpha Formula to check the reliability of the instrument.


36 E. D ATA C OLLECTING T ECHNIQUE Data collection in this study uses the motivational questionnaire in order to understand the students’ motivation toward learning English before and after the treatment, a questionnaire containing some items were developed by the researcher.

37 F. D ATA A NALYSIS T ECHNIQUE The technique of data analysis is examining the effects of the results of the motivational questionnaire. As for the analysis of the motivational questionnaires, each student’s responses to the some items in the questionnaire are scored with the help of the computer software of SPSS.
