Table  2:  The  results  of  professional competence  among
mathematics teachers.
Mastering  learning
materials  and  scientific
methodology
80%  of  teachers  master
learning  materials,  but
30% still have difficulty in
delivering them.
Mastering  the  structure
and curriculum of learning
materials
60% of teachers master the
curriculum  used.  On  the
other hand, teachers have
difficulty  in  meeting  the
administrative demands of
the  curriculum  and
applying  contextual
problems  in  mathematics
learning.
Mastering  and  utilizing
information technology to
improve  the  quality  of
learning
80% of teachers know the
application  or props  used
in  learning  mathematics
but only 20% of teachers
already  use  information
technology in learning.
Table 2 shows that high school math teachers still
need additional  knowledge  of  interactive  learning
models, the way they make contextual questions and
the  use  of  mathematical  applications  in  learning.
Contextual questions are needed because procedural
questions  without  concepts  are  just  rules  that  will
bring  misunderstandings  and  make students  dislike
mathematics (Van de Walle, 2007).
4 CONCLUSIONS
Competencies that must be possessed by teachers of
mathematics  are  pedagogic  and  professional
competence.  The  pedagogic  competencies  of  the
teacher  must be  in accordance  with the curriculum
used in the school. Professional teacher competence
shows  the  teacher's  ability  to  master  the  material
content to be given. Teachers have a major role in
learning.  If  the  pedagogic  and  professional
competence of teachers is not  maximized, then the
ability of students cannot be developed maximally.
