2  External  factors  outside  the  student,  the  environmental conditions around students
3  Learning approach factors, which is the type of student learning effort  that  includes  strategies  and  methods  used  by  students  to
perform activities on the materials of lesson. Based on expert opinions above, we can conclude that learning is
a  change in  behavior of  a person through educational  process,  the changes are influenced by internal factors that come from Students
and external factors that come from outside of the Students.
2. Cooperative Learning Model
After knowing the definition of learning, then will be presented the definition of cooperative learning in the school environment in order to be
a  reference  to  the  settlement  of  problems  that  have  been  described  in previous chapters.
a. Definition of Cooperative Learning Model
According to Hamruni 2012: 119 cooperative learning model is a series of learning activities conducted by students in certain groups
to achieve learning objectives that have been formulated. Cooperative learning is a teaching strategy that implements a system of grouping
small team among four to six people who have different background in academic ability, gender, race, or ethnicity heterogeneous.
Scoring system in cooperative learning is giving awards reward to the group which is able to reach the required achievement. So, each
17
member of the group has a positive dependence. The dependence will bring  the  individuals  responsibility  to  the  group.  Each  student  will
help each other and have a high motivation to be successful group, so each person will have an equal opportunity to contribute to the group.
There are four essential elements in the cooperative learning that are participants, rules, efforts to learn of every member of the group,
and  the  objectives.  Participants  are  students  who  make  the  learning process in each study group. Student groups can be established using
several  approaches,  include students’  interests  and  talents,
backgrounds ability, or a mixture of them. Rules of the group is everything that has agreed by all involved
parties,  both  students  as  Students,  and  students  as  members  of  the group.
Efforts to learn is all activities of students to improve the ability that  has  been  owned  and  led  to  new  capabilities,  good  working
knowledge, attitudes, and skills. The learning activities carried out in group  activities,  so  all  of  the  participants  able  to  learn  through  the
exchange of experiences and ideas. The aspects of interest are intended to give direction of planning,
implementation,  and  evaluation.  Through  clear  objectives,  each member of the group can understand the objectives of each learning
activity.

Lately,  cooperative  learning  strategies  recommended  by education experts to be used. Slavin in Hamruni 2012: 120 suggests
two reasons as follows: 1  Some  studies  showed  that  the  implementation  of  cooperative
learning can improve students’ learning achievement and social
relations in the same time. 2  Cooperative  learning  can  realize  the  need  for  students  to  learn,
solve problems, and integrate knowledge and skills. From these two reasons, the cooperative learning is a form of learning
that can improve the learning system.
