Questioning is the way to generate ideas by asking several questions, such as what, who, when, where, why, and how. The answers of those questions are the
ideas which are used to develop the writing. Chesla 2006: 37-39 states that this technique is particularly useful when students choosing a topic and when focusing
a  topic  selected.  Unlike  some  of  the  other  brainstorming  techniques,  students should ask questions deliberately with  great  thought  given to  each question. The
better  focused  the  answers,  the  more  information  will  be  gathered  to  use  in  the writing.
Questioning is a great brainstorming technique that the questions will help students  quickly  develop  a  great  deal  of  information  about  their  subjects.
However, not every question can be applied to each writing. In short, in applying this technique, students have to be flexible and use the format as it best fits to the
topic.
B. Review of Related Studies
There  are  some  relevant  studies  related  to  the  use  of  the  Brainstorming Technique  in  teaching  writing.  Actually,  brainstorming  is  effective  to  improve
students‟  writing  ability.  The  studies  conducted  in  different  settings  in  which English  is  regarded  as  a  foreign  language.  The  studies  are  described  as  the
following. Al-
khatib  2012  conducted  a  study  entitled  “The  Effect  of  Using Brainstorming  Strategy  in  Developing  Creative  Problem  Solving  Skills  among
Female  Students  in  Princess  Alia  University  College ”.  The  research  findings
showed  that  there  were  statistical  significa nt differences at the level of α = 0.05
between  the  experimental  group  and  the  control  group  in  the  total  score  and  the sub  scores  of  the  creative  thinking  in  the  favor  of  the  experimental  group.  The
research  study  indicated  that  the  use  of  brainstorming  strategy  was  effective  in developing creative thinking skills.
In  addition,  a  study  conducted  by  Noor  2012  entitled  “The  Use  of Brainstorming  to  Improve  S
tudents’  Writing  Skill  in  Descriptive  Text  A Classroom Action Research of the Tenth Grade Students of SMA 2 BAE Kudus in
the  Academic  Year  20122013”.  The  result  of  the  study  proved  that  the implementation of brainstorming technique improved the students
‟ writing skill in writing descriptive text. The research findings indicated the positive direct impact
of implementation of brainstorming technique was shown by the writing test score of students in each cycle.
The studies above prove the effectiveness of the Brainstorming technique to improve students‟ writing skill in educational technique and professional areas.
Brainstorming  helps  the  students  to  build  their  critical  thinking.  Therefore,  the teachers will gain many advantages if they can apply the Brainstorming technique
in their writing class.
C. Conceptual Framework
Writing  is  very  significant  for  learning  English  as  a  foreign  language, especially for high schools students. First, writing is a productive skill that is one
of  the  important  skills  for  junior  high  schools  in  the  English  learning.  It  is  to
convey the messages in a written form. Writing also involves students‟ creativity
in forming a message by creating some signs commas, slashes, quotation marks, and  full  stops,  forming  letters  and  words,  and  joining  them  together  to  make
sentences  on  a  page.  Second,  writing  skill  is  a  basic  skill  in  learning  English which is neccessary to communicate with others by using written language forms
such  as  letters,  emails,  websites  or  social  networks.  Third,  writing  becomes  an important skill that should be mastered well by the students. It is clear that writing
skill is very important in the teaching and learning process. However, the writing ability of gradeVIII students in SMP N 1 Nanggulan Kulonprogo was low. Their
low  ability  deals  with  the  students,  techniques,  materials,  and  media.  Many students  in  this  school  tended  to  assume  that  English  was  a  difficult  subject  to
learn,  especially  writing.  They  also  had  difficulty  in  generating  ideas  and organizing them into good paragraphs. They tended to be stuck in generating ideas
before they really developed sentences into paragraphs. Related to the technique, the techniques applied were less attractive and interactive so it causes difficulties
in  students‟  acquisition.  Related  to  the  materials,  the  materials  being  used  also have a big contribution dealing with the efforts to improve students‟ writing skills.
Most of the materials being taught are boring and monotonous, so the students are not  attracted  to  get  involved  with  the  material.  The  impact  is  that  they  will  not
have  good  writing  mastery.  Related  to  the  media,  teacher  rarely  used  media  in teaching and learning process so that the teaching and learning process will be less
attractive and interesting. Thus, media is important to be used as the teaching and learning aid which helps students to learn in better and easier ways.
Based on the consideration above, the researcher tries to improve students‟ writing skills  by implementing the brainstorming technique. The implementation
of the technique involves the researcher, the English teacher, the collaborator, and the  Eighth  grade  students  of  SMP  N  1  Nanggulan  Kulonprogo.  Then,  the  action
step  consists  of  planning,  implementing,  evaluating,  and  reflecting  the  actions, which  are  carried  out  to  solve  the  problems.  The  students  were  given
brainstorming  technique  in  each  meeting.  It  is  expected  that  there  will  be  some changes in the teaching learning of English at the Eighth grade students of SMP N
1 Nanggulan Kulonprogo after the technique is applied. In summary, it is expected that Brainstorming technique is able to improve
the students‟ writing skill. The implementation of Brainstorming in the teaching and  learning  process  is  expected  to  overcome  the  writing  problems  encountered
by the students of SMP N 1 Nanggulan Kulonprogo.
