B. Theoretical Framework
It  is  obvious  that  now  English  becomes  a  compulsory  subject  for  senior high school in Indonesia‟s education curriculum. It shows that English has been
taught for several years to the students since they were in junior school or even in elementary school. However, the students still obtain some difficulties in learning
English,  especially  in  grammar.  Most  of  senior  high  school  students  obtain difficulty  when  they  try  to  express  their  opinion  or  thought  in  the  writing  form.
Their problem is applying appropriate words, especially prepositions, based on the form of prepositions that they use in their writing. Preposition is a part of English
grammar and it has its own underlying them. Based  on  the  difficulties  of  students  in  applying  preposition  in  their
writing,  the  researcher  gave  more  attention  in  the  errors  in  preposition  which students  made  in  their  writing.  In  this  research,  the  writer  wanted  to  investigate
the kinds of prepositions errors made by tenth grade students of SMA 1 Sapuran, Wonosobo and also to investigate the possible causes of prepositions errors made
by  the  students.  The  data  were  collected  from  the  students  is  about  recount writing.  In analyzing the students‟ recount writing, the researcher  used types of

errors  proposed  by  Dulay  1982 to  identify  the  preposition  errors  in  students‟
writing  assignments  and  forms  of  preposition  classification  proposed  by Greenbaum  and  Quirk  1990  to  classify  the  preposition  errors  which  the
researcher  found  in  students‟  writing  assignments.  The  forms  of  preposition consist  of  four  classification  of  preposition  form  such  as  Place  and  Position,
Direction and Motion, Time, and Manner, Agent, and Instrument. After analyzing the  data,  the  researcher  classified  the  errors  and  then  counted  the  errors.  To
investigate  the  possible  causes  of  errors,  the  researcher  applied  theory  from Norrish 1983:21.
The  researcher  also  conducted  interview,  and  distributed  a  set  of questionnaire  to  tenth  grade  students  of  SMA  1  Sapuran,  Wonosobo  to  obtain
more information about possible causes of errors. The last, the researcher reported the result of the research and draw a conclusion of what had been analyzed.
