                                                                                minimum  two,  or  more,  the  students  are  mutually  searching  for  understanding, solution, or meaning, or creating a product.
Another  expert,  Dillenbourg  1999  states  that  the  definition  of ”Collaborative Learning” is a situation in which two or more people learn or attempt
to learn something together. It can be explained more that the meaning of two or more  people  indicates  that  the  team  consists  of  two  people  who  do  something
together, or more than five people. Hirschy 1995 states that collaboration is the combination of two people or
more,  or  groupwork,  and  an  environtment  where  there  are  variety.  The  higher educated  students  learn  to  expand  the  responsibility  and  to  meet  the  atmosphere
where there are variety in environtment. Gunawan  2003  explains  that  collaborative  learning  process  or
collaborative  learning  does  not  only  work  together,  but  it  leans  on  the  learning process which involves communication process intactly and fairly in the class.  It
can be said that a learning process can be mentioned as collaborative learning when all students in the group have willingness to communicate and share anyting to their
colleagues. Collaborative  learning  activities  are  varied  widely,  but  most  center  on
students’ exploration or application of the course material, not simply the teacher’s presentation or explication of it. In collaborative learning, the students discussion
and their thought in working on the material which is already given are highlighted. In  other  words,  in  collaborative  learning,  every  student  is  expected  to  share
everything, such as skill, ideas, energy, teamworking sense, and problem solving skill.
On the other side, in collaborative learning, the existing processes such as lecturing,  listening  and  taking  notes  are  not  entirely  missing.  The  collaborative
learning process in the classroom, the teachers still have to give explanations, and
students have to listen and take notes.
