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.
