 
Government Regulation No. 19 (MoNE, 2005) that 
states  teacher  competencies  include  personal, 
pedagogical,  professional  and  social  competencies. 
In addition to the four  competencies  mentioned by 
Moore  &  Clarke  (2016),  the  attitude  of  a 
professional teacher is demanded with a number of 
minimum requirements, including: having adequate 
quality  of  professional  education,  having  scientific 
competence  in  accordance  with  the  field  he  is 
engaged in, having good communication skills with 
children  students,  have  a  creative  and  productive 
spirit, have a work ethic and a high commitment to 
the  profession,  and  always  carry  out  self-
development  continuously  (continuous 
improvement)  through  professional  organizations, 
the internet, books, seminars and the like. Speaking 
of  teaching,  the  teaching  style  of  a  teacher  is 
different  from  the  others  during  the  teaching  and 
learning  process  even  though  it  has  the  same 
purpose:  conveying  knowledge,  shaping  students' 
attitudes, and making students skilled in their work. 
The ability to teach also reflects the personality 
of the teacher self and is difficult to change because 
it has become a trait since childhood or from birth. 
Thus,  the  ability  to  teach  becomes  an  important 
factor  in  determining  the  success  of  student 
achievement.  Nairz-Wirth  &  Feldmann  (2019) 
claimed that The ability to teach is a basic skill in 
teachers when the learning process is both curricular 
and  psychological.  Curricular teaching  abilities  are 
tailored  to  the  objectives  and  characteristics  of 
certain  subjects.  Whereas  psychological  teaching 
styles are  tailored to  student  motivation, classroom 
management,  and  evaluation  of  teaching  and 
learning  outcomes  (Gibson,  Cumming,  &  Zollo, 
(2017). So, it can be concluded that teaching is an 
effort to provide direction, guidance, and stimulation 
to  students  in  order  to  achieve  learning  goals  and 
improve learning outcomes. 
In the effort of increasing the professionalism of 
teachers  in  formal  schools  in  particular,  the 
government  always  strives  to  improve  teacher 
quality  through  varios  programs  to  improve  and 
develop  professionalism,  one  of  which  is  by 
participating  in  teacher  certification.  Most  of  the 
teachers who teach in the Elementary School Bogor 
have  taken  certification.  Some  passed  and  some 
others  have  not  passed  the  certification.  Thus,  the 
teaching  abilities  of  certified  and  non-certified 
teachers can be observed. The certification followed 
by elementary school teachers in the city of Bogor 
was  carried  out  through  portfolio  and  teacher 
education  and  professional  training  (PLPG) 
(Directorate General of GTK, 2017). In Period 2006-
2015, Bogor elementary school teachers who passed 
the teacher certification reached 2319 teachers, 1975 
of them were Civil Servant Teachers private school 
(Directorate General of GTK, 2017). data from the 
Directorate General of GTK in 2017),illustrates that 
with  the  majority  of  teachers  who  have  been 
certified,  there is  an  increase  in  teachers’  teaching 
skills  and  it  also  provides  evidence  that  they  are 
appropriate and suitable to teach, The measure of the 
teacher's teaching ability assessment in principle, the 
teacher  must  have  teaching  preparation,  among 
others  the  teacher  must  master  the  material  and 
choose the right method and in accordance with the 
learning  material  being  taught  (Widoyoko,  2009). 
Teacher certification is essential to improve teacher 
quality so as to bring improvements in the quality of 
education  and  improvement  of  teacher  quality  in 
delivering  learning  material  to  students  by 
developing  the  potential  of  their  teaching  skills 
(Kartowagiran, 2011). In the process of obtaining an 
educator  certificate  (certification),  the  teacher  is 
equipped  to become a  professional  teacher,  one  of 
which  is  a  teacher  must  have  teaching  skills 
(Wardoyo & Herdiani, 2017). 
Teachers  in  learning  are  the  spearhead  in 
implementing  quality  learning  (Sumantri, 
Prayuningtyas,  Rachmadtullah,  &  Magdalena, 
,2018).  Teachers  face  directly  with  students  in  the 
class  through  the  teaching-learning  process. 
According to research conducted by Professor John 
Hattie  from  the  University  of  Auckland,  the 
dominant factor that determines student achievement 
is  influenced  by  teacher  factors  of  30%,  49%  of 
students'  characters,  and  21%  of  others  (Hurriyati, 
2017). The research shows the correlation between 
teacher's  ability  to  educational  outcomes.  Some  of 
the  facts  that  the  average  ability  of  prospective 
teachers based on the ability to answer test questions 
for prospective teachers is still below 50%, which is 
only  44%.  The  lowest  ability  is  in  physics  and 
mathematics  competencies  which  only  reach  33% 
and  46%.  In  addition,  the  average  ability 
pedagogical  average  based  on  teacher  competency 
test in 2015 was 56.69% (Hurriyati, 2017). The low 
competency of prospective teachers in Indonesia and 
the  impact  on  graduates  produced  if  students  are 
educated  by  teachers  with  less  competence.  Even 
though  according  to  Campbell  (2019)  teachers  are 
very important in learning because they include non-
social factors that can cause problems in learning. In 
fact the  average  teacher in  Indonesia  has not  been 
able to create an effective learning.
