Furthermore,  Mickulecky  and  Jeffries  state  that  there  are  some  hints  for success  in  extensive  reading.  The  first  is  set  a  goal.  The  readers  should  decide
how  many  books  that  he  or  she  would  like  to  read  during  the  semester.  Second, making reading a part of a daily routine is the next hint. The reader needs to set a
time and place for reading. Reader needs to read at least thirty minutes at a time so  that  he  or  she  can  become  involved  in  his  or  her  book.  The  last  is  keep  a
journal, by writing about reaction to the book or any thoughts that are stimulated by reading can make a reader gain success in extensive reading.
14
One of the bases of extensive reading is self-selection of reading material. Its  meaning  is  students  may  choose  what  they  want  to  read.  Therefore,  it  is
important to pay attention some hints for choosing a book; a.
Choose  a  book  that  interesting.  It  will  make  students  to  be  motivated  in reading.
b. Choose a full-length book, not a collection of articles or stories.
c. Avoid a book whose story that already familiar with because knowing what
will happen may make it less interesting. d.
Evaluate the book. It is necessary to find out about the author and the genre, the style and the subject of book.
e. Check the level of difficulty. To find out how difficult the book is counting
the  number  of  unknown  key  words  on  a  typical  page.  The  book  is  difficult which have five unknown key words on one page and the book is easy which
have no unknown keywords.
15
In  short,  extensive  reading  is  one  of  method  to  teach  English  skill, especially to acquire reading skill. It is believed that it will achieve more success
to develop students’ reading skill, compare with other method. Teacher need to do some preparations in implementing the method in order to get success in teaching
reading. One of the basic preparations in extensive reading is providing the books library  for  students.  So,  they  can  make  their  own  selection  books  to  suit  their
desire and interest.

3. Extensive Reading Course in UIN
Extensive reading is one of the courses which has to be taken by students who have passed Reading I, Reading II, Reading III, and Reading IV course at the
English Education Department. This course is one of many methods to language teaching  which  ask  the  learners  to  read  a  lot  of materials  in  English  for  general,
overall  meaning.  It  is  expected  to  develop  and  improve  students’  reading  skill. Students  will  be  able  to  develop  good  reading  habits,  broaden  their  knowledge,
and  improve  their  vocabulary,  and  to  increase  the  number  of  their  reading materials in certain amount of time.
This  course  aims  to  help  students  to  be  able  to  read  and  to  comprehend reading  materials  from  articles,  novels,  and  textbooks.  Students  are  required  to
read  ten  appointed  English  novels,  eight  appointed  English  textbooks,  and  ten articles from printed English journals. Then, students have to write the review of
the  novels,  the  summary  of  the  textbooks,  the  critical  thinking  essays  of  the articles,  present  one  of
the  novel’s  reviews  andor  one  of  the  textbook’s summaries, and discuss the essays.
Technically,  the  students  need  to  read  those  reading  materials  outside classroom. They have certain target in a week, for instance they need to read one
novel and make the novel review. The novel review is collected a day before the Extensive  Reading  class.  Then  they  have  a  presentation  to  tell  about  the  novel
review  in  front  of  the  class.  Besides,  they  also  have  a  discussion  in  the  form  of questions-answers  session  after  a  student  finishes  hisher  presentation.  However,
the lecturer calls the students to present their readings’ review randomly so they cannot  predict  what  review  they  will  present  in  front  of  the  class,  they  may
present  the  novel,  the  textbook  or  the  article  review  that  has  been  collected.  In addition,  the  extensive  reading  class  has  about  14  contact-hours  to  do  class
discussion.
4. Achievement on Extensive Reading Course
From those definitions before  about  Extensive Reading and achievement, it can be concluded
that students’ achievement on Extensive Reading course is the result  of  students’  effort  to  get  and  understand  knowledge  and  skill  of  reading
through systematic process, practices, and experiences in period of time. Based on the contract of Extensive Reading course, the Extensive Reading
score  consists  of  formative  score  mid-test  score  and  final-test  score.  First  is formative score which consists of students’ presence and students’ participation in
class discussion. Next, individual written works ten novel reviews, eight textbook summaries and ten essays of article is determined the mid test score. These works
must  be  collected  periodically  based  on  the  appointed  time.  The  last  is  final-test score which taken from students’ presentation in front of class. Finally, these three
scores  will  determine  the  final  score  of  students’  achievement  in  Extensive
Reading course.
B. Intelligence Quotient IQ
1. Definition of Intelligence
Intelligence relates to the human brain. It describes the process of brain to learn  and
understand many things in life. People’s intelligence is fundamentally different from each other, in general, in doing many activities of life. In education
area,  students’  intelligence  may  be  shown  in  their  score  of  a  subject.  The intelligence  may  also  affect  how  students  learn  a  subject  in  class.  Moreover,
someone’s  high  intelligence  may  affect  hisher  bright  success  nowadays  or  in future.
The  definition  of  intelligence  has  been  developing  for  many  times.  First, Kush  defines  that  intelligence  is  a  common  factor  that  underlies  all  of  our
cognitive processes or are there multiple, discreet cognitive skills  such as  verbal ability,  numerical  ability,  and  spatial  ability.
16
It  means  that  intelligence  is person’s  general  ability  in  some  mental  activities,  such  as  thinking,  learning,
understanding  and  remembering  which  may  be  reflected  hisher  behavior.

Joseph C. Kush, Intelligence Quotient: Testing, Role of Genetics and The Environment and Social Outcomes, New York: Nova Science Publishers, Inc., 2013, p.2.
Furthermore, intelligence may consist of some areas, such as the ability to speak, the  way  to  express  things  in  numbers,  and  the  process  to  illustrate  or  visualize
things in some ways. Second, Gleitman and his associates broadly put, intelligence refers to the
capacity  that  allows  people  to  acquire  new  knowledge  and  use  it  to  draw conclusions, solve problems,  and adapt  to  new circumstances.
17
Similarly, Smith also s
tates, intelligence is brightness, “sharpness”, ability to solve problem, speed in  figuring  things  out,  and  capacity  to  learn  from  experience.
18
In  other  words, intelligence  relates  to  how  people  think  and  act  carefully,  such  as  in  finishing  a
work, facing a problem, dealing with novel situation, and so on. However, Sdorow and Rickabaugh explain that recognizing the intelligent
behavior, though, is  easier than defining itself.  Intelligence reflects  how  well we function.
19
It  shows  that  intelligence  is  the  reflection  of  people  performance  in their  daily  life.  In  addition,  intelligence  relates  to  how  people  communicate  to
others, learn many things and achieve something as a form their best result of life. Shortly, intelligence is the human individual ability to acquire knowledge
then  apply  it  in  some  ways  of  daily  life  such  as  to  behave  in  surroundings,  do some works, solve problems, and get success. Besides, it also mostly involves the
organization  of  the  human  thinking.  Then,  for  students,  intelligence  may  show their learning style in class and their achievement of a subject.
2. Definition of Intelligence Quotient IQ
The  word  of  IQ  stands  for  Intelligence  Quotient.  Generally,  the  IQ becomes a measurement for people to know someone’s intelligence. The IQ may
reflect  people  performance  in  their  life  such  as  the  behavior  in  daily  life,  the attitude in many things, the way of communications to others, the success of life
