Self Esteem is an evaluation made by 
individuals and habits of seeing themselves 
especially about acceptance or rejection, and an 
indication of the magnitude of individual 
confidence in capability, One’s success, 
significance, and worthiness of himself. The level 
of Self Esteem is a "personal judgment" of a 
valuable or meaningful feeling expressed in the 
individual's attitudes toward him. thus, aspect of self 
esteem studied in this research is capability aspect 
that is showing a high performance to fulfill 
requirement to reach achievement where level and 
duties depend on age variation of someone. 
successness of a person's ability to manage and 
control behavior and gain recognition of the 
behavior from others. The significance refers to the 
concern, attention, affection and expression 
received by someone from others who show the 
acceptance and popularity of the individual from the 
social environment. Worthiness implies an 
obedience to the moral and ethical standards and 
religions in which the individual will stay away 
from behaviors that should be avoided and conduct 
the behavior permitted by morals, ethics and 
religion. 
The beginning of a healthy self-esteem coaching 
is to teach students to understand who they are, 
especially with regard to the advantages and 
disadvantages of the students. In the context of 
statistical learning, the environment in question is a 
statistical learning activity that involves the active 
participation of all students in implementing the 
teacher's teaching. The goal is no other to provide a 
successful experience through awarding (rewards that 
become part of the feedback) to each student so that 
each student is able to appreciate the advantages 
possessed by each student. 
A person with high self esteem tends to be more 
attractive to have a good relationship with others and 
can make good impressions than those with low self 
esteem (Braumeister, 2003). In a group, a person with 
a high self-esteem tends to be more daring to appear 
and critical of his group. Although not directly 
affecting self-esteem can also affect the nature of 
one's leadership. This is because someone with high 
self esteem tends to be superior than those who have 
low self esteem. 
According to Alhadad (2010), students with high 
self-esteem look more optimistic, confident, and 
always be positive about everything, also against the 
failure that happened. At the time of failure, students 
with high self-esteem tend to see the failure not as the 
end of everything, but make the failure as a valuable 
experience to move forward. Looking at the mistakes 
that have been done before as a valuable lesson and 
provision to achieve better results, it is because the 
success basically achieved at this time can not be 
separated from mistakes that have been done before. 
Students with high self esteem, able to appreciate 
himself and see the positive things that can be done 
for success in the future. 
On the contrary, students who have low self-
esteem believe and see that he is weak, unable to do 
nothing, not have the ability, tend to feel himself 
always failed, unattractive, disliked, and lose the 
appeal to life. Students with low self esteem tend to 
be pessimistic about life and opportunities. They do 
not see a challenge as an opportunity, but rather as an 
obstacle, give up easily before trying and when they 
fail, blame themselves and blame others. It is possible 
that the low self-esteem of students can negatively 
affect their learning achievement. Therefore, self 
esteem needs to get special attention from parents and 
teachers. 
Teachers and parents should focus on developing 
student self esteem, because with high self esteem 
many positive things that can arise from the students. 
Braumeister (2003) also stated that high self esteem 
is a part of good student achievement in school. 
According to Alhadad, low student achievement in 
mathematics lessons tends to frustrate students. 
Students will assume that forever they will not be able 
to achieve a good achievement in math lessons. When 
dealing with mathematical problems, students feel 
desperate and think they can not solve them, even 
before they make the most of their efforts to solve 
them. Attitudes like this certainly can negatively 
affect the development of students in the learning 
process. Therefore, teachers as educators have an 
important role in building and developing self esteem 
students. 
One effort to develop self esteem of students is by 
giving responsibility to students in learning (Muijs 
and Reynolds, 2008). Teachers can assign tasks to 
students in the form of challenging issues and give 
them confidence and convince them that they can 
accomplish these tasks well. Teachers can reward or 
appreciate the results of student work. even they are 
simple  ideas, opinions, questions, or results obtained 
by students, teachers still give appreciation to 
students wisely. When students make mistakes, the 
teacher must make sure that the error is part of the 
learning process, not a failure. With this process, 
students will feel appreciated, needed, and will slowly 
awaken confidence and pride in themselves. 
In addition, students' learning environment also 
affects students' self-esteem. As according to Tran 
(2012) that the learning environment is very
