C. Research Instruments
To  obtain  the  data for  this  study,  some  instruments  employed  in  research and  information  collecting  and  preliminary  field  testing.  The  instruments  are
interviews and questionnaires.
1. Interviews
An interview is a way of people’s feelings, thoughts, beliefs, and opinions by asking them some questions related to the issuestopics being investigated. The
responses of the interviews are taken by recording using a tape-recorder or taking notes Ary et al., 1979: 434.
In this study, an informal interview was conducted to the English teachers of  SMA  Santo  Bernardus  Pekalongan.  To  conduct  the  interview,  the  writer
employed  an  interview  guideline  consisting  of  some  questions  to  obtain information on learners’ background knowledge, lacks, needs, and interests from
the  teachers’  perspectives.  An  informal  interview  instrument  was  conducted  in pre-design section.
2. Questionnaires
A questionnaire is a list of questions asking about people’s opinion. It is a printed  form  of  data  collection  containing  some  statements  or  questions  to
respond.  There  are  two  types  of  questionnaires,  namely  close-ended  and  open- ended questionnaires. Brown and Rodgers, 2002: 120. The closed form items are
used  to  make  it  easier  for  the  respondents  in  filling  the  questionnaires  since  the
answers are available. On the other hand, the open form items are used to obtain more  information  from  the  respondents  because  they  are  permitted  to  answer
freely. In  this  study,  the  writer  distributed  two  kinds  of  questionnaires.  The  first
kind  of  questionnaire  was  distributed  to  the  eleventh  grade  of  students  of  SMA Santo  Bernardus  Pekalongan.  Moreover,  it  was  conducted  in  pre-design  section
since  it  functions  to  obtain  the  data  concerning  students’  capabilities,  needs, interests, and background knowledge viewed from the perspective of the students.
The second kind of questionnaires was distributed to the English teachers of SMA Santo Bernardus Pekalongan and some lecturers of the English Language
Education  Study  Program  of  Sanata  Dharma  University.  This  kind  of questionnaires was distributed to obtain feedback and suggestions to improve the
designed  set  of  the  materials.  The  data  gathered  were  then  used  as  the  basis  to revise  the  designed  set  of  the  materials.  There  were  two  sections  in  the  second
questionnaires.  The  first  section  of  the  questionnaires  was  close-ended  and consisted of some statements investigate participants’ opinion on the designed set
of  the  materials.  In  the  first  section  of  the  questionnaires,  the  response  to  each statement was expressed in a scale of 1 to 5. The participants completed the first
section  of  the  questionnaires  by  choosing  one  of  five  alternatives  provided. Meanwhile,  the  second  section  of  the  questionnaires  was  open-ended  and
consisted  of  some  questions  to  elicit  participants’  personal  opinions  and suggestions to improve the designed materials. The questionnaires instrument was
done in post-design section.
To  avoid  misunderstanding  and  to  ease  the  respondents  in  answering  the questions, the questionnaires were written in Indonesian. This was meant to make
it easier for the respondents to catch the points of the questions and would not find any difficulties in filling the questionnaires provided.
