C. Participants of the Research
The  participants were the  researcher  in  collaboration  with  all  the research  members.  They were  the  school  principal,  the  English  teacher,  the
researchers, and the students of SMP 3 Berbah; especially the students of class VIII D in  the  academic  year  of  20132014. The  research  involved  all  22
students of class D grade VIII. The  English  teacher of  grade  VIII  was  also  involved  in  this  research.
The English teacher participated in this research as a collaborator. The teacher observed  the  research,  gave  information  in  the  thematic  reconnaissance  step,
gave opinions about the  plans that were implemented and the implementation of peer response in the teaching-learning process. The collaborator also became
the second rater for students’ score.
D. Instruments of the Research
The instruments used in this research are presented below. 1. Interview Guideline
The interview guideline was used to interview the English teacher and the  students  during  the research.  The  interview  was  done  in the
reconnaissance and action steps. 2.  Observation Checklist
The  observation  checklist  was  used  to  check  the  application of peer response  in  the teaching  and  learning  process.  The  researcher and
collaborators put  mark  to  the  statements  of  writing  processes  which  had been done.
3.  Writing Tests Students’  writing  tests  were  used  as  the instrument to  get  the
information  about  the  students’  writing  ability  after the peer  response  was applied. The  tests could inform whether  there  was  improvement of the
students’ writing ability after implementing the peer response.
E. Data and Technique of Collecting Data
There were two types of data in this research. They were qualitative and quantitative  data.  The  qualitative  data were the  description  of  the  process
during the action. They were obtained by interviewing the English teacher and the  students  of  class  VIII D,  observing  the  teaching  and  learning  English
process  in  class  VIII D,  and  also  the  documentation. The results  of  the observation were in the form of field notes. The data from the interviews were
in  the form  of  interview  transcripts.
Meanwhile, the  photograph
documentations were to  support  the  data  mentioned  previously. Those  were also supported by student’s writing task submitted back by the researcher.
Besides, the  quantitative data were the  result  of  the  students’  writing
before, and after the action. It was a kind of writing test to see the difference of students writing before and after implementing the technique. It included a pre-
test  that was done  to  get  the  score  of  the  test  before  the  treatment.  Later  on, there was a  post-
test  to  obtain  the  score  of  the  students’  writing  after  the
treatment.  It was  not  only  to  see  the  improvement  of  students  writing  scores, but also to see their improvement inside their writing composition.
In the reconnaissance step, the researcher observed the learning process of the  class  together  with  the  collaborator  to  get  information  related  to  the
English  teaching  and  learning  process.  The  researcher  also  interviewed the English teacher and the students to know more about the difficulties happened
in the teaching and learning process. In  the  planning  step,  the  researcher had  a  dialogue  with  the  English
teacher as the collaborator to decide what kind of technique to apply in order to solve the problems, here, to improve the writing ability of grade VIII students
in the school. To achieve the democratic and process validity of the study, the researcher asked for the collaborator’s opinion and suggestion.
The next step was action and observation. The teaching was done by the researcher, while  the  observation  was  conducted  by  the  collaborator.  To
achieve  dialogic  and  outcome  validity,  besides  the  observation,  some interviews
were conducted  after
the implementation.
The researcher
interviewed the English teacher and  the  students  about  the implementation  of peer response
to improve the students’ writing ability. After the action step was done, the researcher reflected on the results of
the action. The results of the studen ts’ writing were evaluated together with the
collaborator.  What  was  improved  and  what  to  be  improved  in  the  next  cycle were  discussed  with  the  English  teacher  as the collaborator.  The  researcher
used  documentation  to  record  the  students’  activities  in  producing  the  written
texts.    The  process  of  documentation  in  the  implementation  was  done  by  the collaborator.  Content  and  outcome  validity  were  expected  to  be  achieved
in this process.
