47 the best  quality of  collaborative learning  as  each of them is  responsible for their
own learning and others’ within the group. Johnson, Johnson, and Smith 1991 coined elements that learners should
demonstrate in
the collaborative
learning process,
namely positive
interdependence, individual accountability,  face-to-face promotive interaction, as well  as  appropriate  use  of  collaborative  skills  and  group  processing  as  cited  in
Maesin,  Mansor,  Shafie,    Nayan,  2009.  Other  that  those,  collaboration  in speaking  class  takes  students’  ability  to  interact  and  communicate  in  the  target
language  in  order  that  they  are  enabled  to  exchange  opinions  and  ideas. Otherwise,  the  collaboration  process  will  not  work  according  to  the  actual
intention of the speaking class itself. Apart from that, all these collaboration skills can only be performed with students’ willingness and voluntary contributions.
In  this  action  research,  one  of  the  learning  process  components investigated was students’ collaboration skills. Chang 2012 and Lin 2015 note
some characteristics that indicate whether students perform collaborative learning throughout  the  learning  process.  First  of  all,  students  demonstrate  collaboration
when each of them actively contributes in working with peers, so that  they share the responsibility for the learning outcomes Lin, 2015, p.14. Secondly, students
realize that their success in learning also depends on others. Therefore, they care about  others  and  support  each  other  regardless  of  their  competence  levels,  both
inside and outside the classroom Chang, 2012. The forms of support are shown when  students  read  each  other’s’  assignment  as  well  as  give,  receive,  and
exchange  feedback  for  peers’  learning  development.  Finally,  students  in PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI
48 collaborative  learning  classrooms  realize  that  everyone  has  equal  opportunity  to
succeed, so there is no sense of competition among them. In this study, students’ collaboration skill is observed through their actual
collaborative learning performance inside the classroom. As their collaboration in learning  both  inside  and  outside  the  classroom  matter,  it  is  necessary  to  also
analyze  the  improvement  of  students’  collaboration  skills  based  on  students’ responses to the pre- and post-program questionnaire.
b. Autonomy
The  discussion  of  learner’s  responsibility  is  raised  in  collaborative learning  environment.  A  learner’s  capability  in  learning  independently  and
responsibly  deals  with  the  concept  of  autonomy.  The  concept  of  autonomy  in education has drawn much of educational researchers’ attention since 1970s Ma
Ma, 2012. Accordingly, in recent language teaching studies, the importance of helping learners to become more autonomous has become a prominent issue. This
is because learning autonomy is one of the keys for learner’s success in language
learning. In its classic definition, autonomy is the ability to take control over one’s
own learning through the ability of making significant decisions about what, how, and when to learn Holec, 1981, as cited in Chan, 2000; Van Lier, 1996, as cited
in  Chan,  2000.  In  other  words,  it is  “the  capacity  to  take  charge  of,  or
responsibility  fo r,  one’s  own  learning”  Benson,  2011,  p.58.  To  describe
autonomy  in  language  learning  context,  Benson  2011,  p.59-61  intertwines PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI
49 Holec’s 1981 definition of learning autonomy, which covers the main areas of
the  learning  process  controlled  by  autonomous  learner, and  Little’s  1991
definitions,  which  emphasizes  on  learner’s  control  over  the  cognitive  processes through a psychological dimension as well as learning content. Based on this, he
argues that “an adequate description of autonomy in language learning should at least  recognize the importance of three dimensions  at  which learner control may
be  exercised:  learning  management,  cognitive processes,  and  learning  content.”
Benson,  2011,  p.61.  In  other  words , learner’s autonomy is manifested in one’s
ability  to  self-control  over  those  three  dimensions  of  learning,  although  there could be various forms of control over learning performed by different individuals
in different contexts and in different times Benson, 2011, p.58. Fostering  autonomy  in  learners  can  be  done  by  developing  a  sense  of
responsibility  as  well  as  encouraging  learners  to  take  an  active  part  in  making decisions  of  their  learning  Scharle    Szabo,  2000,  p.4.  This  notion  clearly
explains that it is highly potential that student autonomy  can be fostered through the principles of collaborative learning applied in this action research, just as Lin’s
2015  argument.  Further  in  her  study  on  collaborative  learning  conducted  in  a ESL speaking class Lin, 2015, she found that students were more self-dependent
in  their  learning  both  inside  and  outside  the  class,  which  indicated  that  learners became  more  autonomous  as  they  actively  made  contributions  in  collaborative
learning environment. Students’ autonomy becomes one of the focuses of this study since learner
autonomy is one of the most influential aspects in learning process, particularly in PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI
50 a speaking class of mixed-
competence learners. Students’ autonomous learning, in fact,  emerges  during  the  learning  process  in  collaborative  learning  environment.
Whether  or  not  every  student  becomes  more  autonomous  during  the  action research  cycles  was  investigated  through  direct  classroom  observation  on  their
learning performance, as well as their responses to the interview.
B. REVIEW OF RELATED STUDIES
It is not easy to find studies related to teaching mixed-competence classes conducted in  Indonesia.  Because of this,  some related research reports discussed
in  this  section  are  from  overseas.  Research  on  mixed-ability  classes  is  a  fertile ground  of  study  since  there  are  many  aspects  to  investigate  Xanthou    Pavlou,
2010.  In  fact,  globally,  there  have  been  a  number  of  research  investigating different aspects of teaching classroom with mixed-competence learners, or what
is commonly addressed with mixed-ability classes. Xanthou and Pavlou are two education researchers from Cyprus who have
been focusing their studies on teaching in EFL mixed-ability class or MAC 2008, 2010. In their 2008’s study, they investigated how EFL teachers in Cyprus deal
with  MAC,  especially  with  regard  to  students  with  pre-existing  knowledge  of English  PKE.  Data  were  collected  from  questionnaire  responses  obtained  from
114 state primary school EFL teachers, and observation in level 1 EFL class of an urban primary school consisting of 25 children of mixed abilities. Those different
forms  of  data  were  then  compared .  The  study’s  main  finding  was  that  flexible
grouping  mixed  and  same  ability  groups,  cooperative  and  communicative PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI
