To  answer  the  research  problem,  the  researcher  uses  the  theory  of collaborative  learning  by  Johnson  et  al  who  state  that  there  are  five  elements  in
applying collaborative learning. While students apply the elements of collaborative during  learning  process,  students  will  gain  skills  through  it.  Those  collaborative
elements are perceived positive interdependence;  elements are perceived positive interdependence,  considerable  interaction;  individual  accountability  and  personal
responsibility;  social  skills,  and;  group  self-evaluation.  Through  collaborative elements, the researchers can see how far the students built collaborative skills.

CHAPTER III RESEARCH METHODOLOGY
CHAPTER III. RESEARCH METODHOLOGY
This chapter discusses about the method that is used for this research. There are seven parts in this chapter, which are research method, research setting, research
participants,  research  instruments,  technique  of  data  analysis,  triangulation,  and research procedures.
A. Research Method
Research  method  is  a  step  in  science  which  is  done  to  gain  factors  and principles  patiently,  and  systematically  to  show  or  to  get  truth  or  facts
Sugiono:2008. This study employed a Mixed Method approach. Creswell 2012 emphasized that Mixed Method approach is a research that uses a combination of
qualitative and quantitative approaches. Neuman 2014 states that qualitative and quantitative research methods are two different approaches, but they complement
each other. Therefore, the researcher will gain the best analysis. In  this  research,  the  researcher  used  the  explanatory  sequential  design.
Creswell  2012  states  that  the  sequential  explanatory  strategy  is  a  technique  to analyze the data by  analyzing the data using  the  qualitative approach in the first
stage, followed by the use of qualitative to support the results of the quantitative. Thus, in the Sequential explanatory method, the data is analyzed using quantitative
technique  at  first.  The  researcher  used  survey  to  gain  the  data.  After  emerging PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI
