4. The Research Instruments
There were some research instruments used in this study. While gathering data,  the  writer  used  questionnaires.  Checklists  and  tables  were  used  while  the
writer analyzed the data. Questionnaires  were  distributed  to  the  respondents  to  obtain  information
concerning  respondents’  facts,  and  intention.  There  are  two  types  of questionnaires, open-ended questions and close-ended questions. This study used
questionnaires  with  close-ended  questions  because  “they  are  more  easily processed”  Babbie,  1973:  141.  Through  questionnaires  handed  out,  the  writer
knew  facts  about  respondents’  personal  data,  respondents’  language  usage,  and respondents’  process  and  efforts  of  learning  English.  The  writer  could  also  gain
information about respondents’ intention of learning English. Checklists were very important when the writer analyzed the data because
“checklists  are  mnemonic  devices,  i.e.,  they  reduce  the  chances  of  forgetting  to check  something  important.  They  reduce  errors  of  omissions”  Scriven,  2005  as
cited  in  http:www.wminch.eduevalctrchecklistspaperslogic_methodology.pdf , accessed on August 20, 2007. Checklists were used to help the writer answered
the  first  and  second  problem.  This  checklist  was  useful  because  it  helped  the writer to categorize types of sentences produced by the respondents, whether they
were  correct  or  incorrect  sentences.  The  types  of  sentence  patterns  had  been discussed  in  Chapter  II.  They  were  simple  sentence,  compound  sentence,  and
complex  sentence.  Since  this  checklist  helped  to  categorize  types  of  sentences,
this  checklist  was  named  Sentence-Type  Checklist.  Below  is  an  example  of Sentence-Type Checklist.

The reference column was for the numbers of line or lines in which certain sentences  analyzed  could  be  found.  They  were  categorized  as  a  correct  or
incorrect sentences by giving a tick   in the column “Correct” or “Incorrect”. Of course, a sentence could only be a member of one category. This categorization of
whether  or  not  the  sentences  are  correct,  helped  the  writer  to  anwer  problem formulation number two.
In the Sentence-Type Checklist, the writer categorized the type of sentence by giving a tick   to the most appropriate type of sentence in the next column.
This  checklist  was  used  to  answer  the  Problem  Formulation  number  one  about types  of  sentences  produced  by  tour  guides  in  Prambanan  Temple.  Obviously, a
sentence could only be a member of one category of types of sentence, whether it is a simple sentence, compound sentence, or complex sentence.
