4  FINDINGS AND DISCUSSIONS 
 
Based on the research that has been done, the 
following results are obtained: 
 
4.1 Observation Results 
Observations were made of 25 high school/ 
vocational high school teachers in Banda Aceh, both 
public and private one. Development of observation 
instruments based on professional competence of 
high school / MA / vocational mathematics teachers 
under Minister of National Education Regulation No. 
16 of 2007 concerning Academic Qualification 
Standards and Teacher Competence. 
a.  Competence in mastering the material, structure, 
concepts, and scientific mindset that supports the 
subjects being taught: 
In mastering the material, structure, concepts, 
and scientific mindset that supports mathematics 
subjects, high school / vocational high school 
teachers in Banda Aceh are very good. There are 
20 teachers who are able to teach without using a 
manual. Most material taught is able to be 
delivered in the order of book. Moreover, some 
teachers have a quick way to solve mathematical 
problems. The problem is that the teacher is 
unable to instill knowledge and thought patterns 
in students.  
The curriculum demands that must be 
achieved cause teachers do not have many 
opportunities to transfer the scientific mindset to 
their students. For this problem, teachers need to 
be invited to open their insights about learning 
models where teachers and students can interact 
with each other without disregard understanding 
and scientific mindset value. For example, by 
implementing a learning model of Problem Based 
Learning, Discovery, Jigsaw, Group 
Investigation, and others. Teachers need to foster 
the spirit of understanding the subject matter by 
sharing the benefits of learning the material being 
discussed. The constraints that exist to implement 
the learning are the lack of knowledge and 
opportunity for teachers to obtain knowledge. The 
training provided by the government is not evenly 
distributed. The government that has the authority 
to deal with improving the quality of teachers 
must provide training calls directly to the teacher 
in concern. 
b. Competence in mastering Competency Standards 
(SK) and Basic Competencies (KD) subject / 
development fields that are taught. 
Twenty five (25) teachers master the 
competency standards and basic competencies of 
the subjects that they receive. However, many 
teachers do not understand how to develop 
indicators from SK and KD that are outside of the 
indicators already in the guide. This is one of the 
causes that the teacher is not able to integrate the 
material to be taught to the abilities that students 
must achieve in accordance with the times. 
c.  Competence to develop learning materials that are 
taught creatively.  
About 16 teachers (64%) did not have time to 
develop study materials that support the material 
that must be conveyed to students. Demands for 
teaching hours, detailed assessment and 
evaluation systems, and self-development for 
promotion make teachers do not have adequate 
time to look for prerequisite and other supporting 
material. 
d. Competency to develop professionalism on an 
ongoing basis by doing reflective actions.  
A lot of reading, discussion, and attending 
seminars related to this condition will greatly help 
the teacher in carrying out his profession. 
Competency to develop professionalism is rarely 
done by the teacher intact. For example in 
attending training and seminars. Nearly 88% of 
teachers who take part in seminars and training 
only want the certificate given even by paying but 
do not expect the knowledge that is presented 
even though it's free. 
e.  Competence to utilize information and 
communication technology to envolve 
themselves.  
This competence highly plays an important 
role for teachers as people who are dealing 
directly with students. From the results of the 
research (observation and interviews), teachers 
over 50 years old are lacked of technology but 
they communicate well with their students. On the 
opposite, teachers under 50 years old have good 
skill on information technology but are not good 
at communicating. This problem can be solved by 
disclosed communication between fellow 
teachers and teachers with students. Teachers 
must realize that communication is fundamental 
while technology can be learned from everyday 
practice. Therefore, teachers who have good 
technological skill to be willing to teach 
underprivileged teachers during they free time at 
school.
