C. Research Participants
Ary,  Jacobs, and Sorensen 2010 define population as to all  members of any  well-defined  class  of  people,  events,  or  objects  p.  148.  The  population  of
this research was the sixth semester students of the English Language Education Study  Program  ELESP  of  academic  year  20082009  at  Sanata  Dharma
University who were taking Micro Teaching Course KPE 373 in academic year 20102011. There were seven classes of micro teaching class and there were 20 to
22 student teachers for each class. According  to  Ary,  Jacobs,  and  Sorensen  2010,  in  purposive  sampling-
also  referred  to  as  judgment  sampling-  sample  elements  judged  to  be  typical,  or representative,  are  chosen  from  the  population  p.  156.  In  this  research,  the
researcher  took  eight  students  who  were  conducting  the  teaching  practice  in Reading  Class,  Speaking  Class,  Listening  Class,  and  Writing  Class.  While  from
each  class,  the  researcher  observed  two  students  as  the  representative  of  each class. Since there were four classes to be taught by the student teachers, therefore,
eight students were required.  The respondents were purposively chosen based on the subject of the course at Sanata Dharma University that involved the productive
and  receptive  skills.  They  were  reading  and  listening  as  receptive  skills  and speaking and writing as productive skills.
D. Instruments and Data Gathering Technique
In  carrying  out  the  data  in  the  study,  the  researcher  employed  four instruments  namely  observation  checklist,  observation  note,  questionnaire,  and
24 guiding  questions  for  interview.  The  observation  checklist  see  Appendix  B
contained  some  points  about  what  to  be  observed.  The  researcher  attempted  to discover  any  information  about  the  classroom  management  conducted  by  the
ELESP  student  teachers  and  the  classroom  management  problems  occur  in  the student teachers teaching practice. In the first part of observation checklist close-
ended  part  helped  the  researcher  to  answer  the  first  research  question  and  the second part of observation open-ended part helped the researcher to answer the
second research question. The  second  instrument  employed  in  this  research  was  observation  note
see Appendix H. The researcher attempted to discover the respondents’ teaching performance  related  to  the  classroom  managements  conducted  by  the  ELESP
student teachers and also the classroom management problems occur in managing the classroom.  Meanwhile, the observation note see Appendix H was employed
to  help  the  researcher  to  answer  the  second  research  questions  on  the  classroom management problems that occur in the student teachers teaching practice.
The  third  instrument  employed  in  this  research  was  questionnaire  see Appendix D. It contained some questions that should be answered by the ELESP
student  teachers.  The  questions  were  designed  from  the  observation  checklist  in order  to  find  out  their  own  evaluation  after  conducting  the  teaching.  The
questionnaire  consisted  of  two  different  parts.  The  first  part  was  close-ended questions  which  consisted  of  a  set  of  statements  where  the  respondents  just
needed  to  give  check  mark  or  cross  mark  on  the  options  given.  Besides,  the respondents could give additional information in the space provided. The second
25 part  was  open-ended  questions  which  were  a  set  of  questions  where  the  ELESP
student  teachers  could  give  their  reason  why  problems  occurred  during  the teaching  activities  and  how  they  solved  the  problems,  and  also  what  classroom
management that they have conducted well. The close-ended part of questionnaire was  aimed  to  help  the  researcher  to  answer  the  first  research  question  while  the
open-ended part to answer the second research question. The  fourth  instrument  was  guiding  questions  for  interview.    The  guiding
questions for interview see Appendix F contained some questions that should be answered  orally.  The  guiding  questions  for  interview  was  employed  in  order  to
ensure and cross-check the data of the researcher data from observation checklist and the data of the respondents data from the questionnaire about the classroom
management  conducted  by  the  ELESP  student  teachers.  The  guiding  questions helped the researcher to answer research questions number one and two.
Having  the  instruments,  the  researcher  employed  some  techniques  to obtain  the  data  required.  The  first  was  conducting  the  observation  to  eight
respondents  in  two  different  classes.  They  were  two  students  of  the  ELESP student teachers who conducted teaching in Reading Class, two students taught at
Speaking Class, two students taught at Writing Class, and two students taught at Listening  Class.  The  observations  were  aimed  to  discovering  the  classroom
management  conducted  by  the  ELESP  student  teachers  and  the  classroom management problems occur in the student teachers teaching practice. Before the
observation  was  employed,  the  researcher  explained  to  the  respondents  that  the researcher  would  only  observe  the  respondents’  performance  in  teaching.  As  a
26 result,  the  researcher  observed  eight  student  teachers  on  their  teaching
performances and completed the observation checklist when the  student teachers were  teaching  the  lower  semester  students. The  observations  were  conducted  on
4
th
, 6
th
, 9
th
-11
th
, and 20
th
of May 2011 when the ELESP student teachers taught the lower semester students.
After the respondents conducted the teaching, the respondents were given the  questionnaire  as  the  second  step.  It  was  employed  in  order  to  gain  the  data
from the point of view from the respondents. The questionnaires were distributed to each ELESP student teacher after they conducted the teaching. It was aimed to
recall  the  student  teachers’  teaching  performance  during  the  teaching  activities. Therefore, the questionnaires were distributed to eight students on 4
th
, 6
th
, 9
th
-11
th
of May 2011. After the questionnaire and the observation checklist were completed, the
next  step  was  examining  the  data  from  the  respondents  and  the  observation checklist. The researcher analyzed the data from the observation checklist and the
data  from  the  questionnaires  to  find  out  the  different  data  that  the  researcher obtained.
Then, the researcher conducted the guiding questions for interview to eight students  of  the  ELESP  student teachers  on  14,  15,  17,  and  20  June  2011,  and  8
August  2011.  The  researcher  conducted  the  guiding  questions  for  interview  in order  to  obtain  more  information  and  reason  from  the  respondents  about  the
different  data  obtained  by  the  researcher.  In  addition,  guiding  questions  for
27 interview employed to ensure and cross-check the data taken in order to validate
the data of the researcher. After  obtaining  the  data  from  guiding  questions  for  interview,  the
researcher examined the result of guiding questions for interview to be compared to the result of observation checklist and questionnaire data. Finding the data from
three instruments, the researcher employed the observation checklist result as the main data. While the result of questionnaire and guiding question for interview are
as  means  to  help  the  researcher  to  find  what  components  of  classroom management  are  conducted  and  are  not  conducted.  Meanwhile,  the  result  from
observation note and open-ended parts of observation checklist and questionnaire are  a  means  to  help  the  researcher  to  find  out  the  problems  which  occur  in
managing the classroom.
