from other normal children. Their attitudes to 
strangers are rarely greeted and embarrassed. They 
will be very nice to the known person although they 
tend to not talk and put smile if they meet. 
Spiritual attitudes depend on habits in the family, 
school, and neighbourhood. For example, do the 
greeting with friends, shake hands to teachers and 
friends, and pray before eating and others. They 
respect each other as well as  one religion and 
another. In religious terms, their parents and teachers 
always guide them to worship according to their 
beliefs, eventhough sometimes they do not 
understand. 
In terms of social interaction, children with 
special needs considered their teachers and friends 
are friends without differentiation. This is because 
they do not yet understand the meaning of mutual 
respect for the elderly because they consider 
everyone around him is equal and same with their 
age. They frequently gather together with people 
they like which mean “picky” of friends. 
In facing problems, tunagrahita children in SLB 
Biromaru tend to be alone, quiet, nervous, easy to 
cry, often singing alone to calm himself, and ask the 
liked people, teachers, friends as well as those 
around the school environment when encountered 
difficulties in the lessons.
 
The ability of tunagrahita children in SLB 
Biromaru in taking care of himself is very poor, due 
to the less responsive parents and the environment to 
their circumstances. Therefore, the teachers always 
teach and guide them to be able to take care of 
himself. 
  Characteristics of Tunagrahita Child 
Tunagrahita children has characteristics in which 
the head is larger and ear is smaller than normal size. 
They also have childish face or not appropriate with 
their age (baby face), have uncomfortable behaviour, 
and like walking around. Besides, they are shy, not 
confident, slow thinking, hard to control, emotional, 
and often shouting. However, they show good 
perseverance and empathy if they get conducive 
service or a treatment. 
In addition, they tend to behave like a child and 
have unstable emotions looked from facial 
expression because of their changed feelings 
according to the mood. Their intellectual 
development is slow and difficult to concentrate in 
learning. The differences between tunagrahita 
children and tunarungu (deaf) children are they are 
easier to communicate even with minimal 
vocabulary. The emotions are more controlled but 
the concentration is lower than the deaf child. 
Tunagrahita children still have obstacles in 
ability to speak and communicate because their 
vocabulary is limited which tend to produce the 
repeated word in communicating as well as they 
sometimes do not get into the conversation. 
  Teaching Method of Tunagrahita Child in 
SLB Biromaru 
The given education to tunagrahita children in 
SLB Biromaru has the same treatment as other 
SLBs, which concerned in terms of how to dress; 
how to speak; how to take action and how to interact 
between students and teachers. 
Teachers teach based on the student's disabilities 
and provide learning subjects that always in 
accordance with their abilities. Teachers give more 
attention and patiently guide their students one by 
one using varied lecture methods, discussions, 
games, and held a study tour. Although with not 
adequate the facilities and infrastructure, this school 
is able to well educate children with special needs. 
Teachers in giving lessons to tunagrahita 
children have to follow their mood. Without a good 
mood, children tend to get bored quickly and cause a 
sense of lazy in learning. The teacher gives 
repetitive lessons so that the tunagrahita children are 
able to repeat gradually the lesson studied,. 
In teaching, the use of props with various forms 
of visual is very necessary because it will make 
children understand the lessons taught. In addition, 
this kind of learning method is more fun for 
children.  
In terms of spiritual and religious activities, 
teachers teach how to worship according to their 
religion, as well as show them appropriate places of 
worship. In terms of social life, teachers teach them 
to care about the surrounding and provide assistance 
if people requires help. Teaching and learning 
activities are sometimes done outside the classroom, 
closer to nature.
 
Evaluation of learning is also given to 
tunagrahita children. It should be done after 
studying one small part of the learning subject to 
find out the outcomes learning before continuing to 
the next lesson. Evaluation tools should be in the 
form of performance and the qualitatively processed 
results while quantitative assessment is made as 
required..
 
SLB Biromaru has implemented a curriculum 
from the education ministry tailored to the student's 
abilities related to children with special needs. The 
average age of tunagrahita learners are from 25 to 
30 years. It shows that there is no existing age 
problems relating to children with special needs.
