Future of a nation can be guaranteed. If not, it will cause serious threats to the survival of a nation. Schools are official educational institutions that carry out teaching and learning activities (KBM) as an effort to achieve educational goals. The level of education quality is influenced by the quality of the learning process carried out by the teacher, because the teacher directly provides subject matter directly to students [1].
Besides that, of course every institution or educational institution has a leader. The principal is a leader in educational institutions that regulates and manages educational activities in schools. Therefore, currently school principals play an important role in improving the quality of education, especially improving teacher The role of the supervision of the school chairman... performance to be more enthusiastic and professional in teaching and developing themselves in charge of delivering lessons to their students.
This shows that teachers are expected to be able to play an active role as managers of the teaching and learning process, act as facilitators who always try to create class organizations, use teaching methods and teacher attitudes and characteristics in managing the teaching and learning process [2]. Furthermore, [3] explains that the principal as a supervisor has the responsibility for increasing the ability of teachers to manage learning activities in schools and has a very important role in the development and progress of a school.
Based on this, the principal must supervise properly and correctly in accordance with the principles and techniques as well as the right approach. Coaching carried out by the principal to the teacher can improve teacher performance and dedication in education. Supervision is carried out by the principal, namely to improve the competence of teachers in teaching and learning activities, so that they are expected to fulfill the teaching mission they carry or the national education mission in a wider scope. As is well known, the problem of the teaching profession in carrying out teaching and learning activities will always and continue with supervision assistance from the principal [4].
Furthermor, [4] argues that the purpose of supervision is to develop a better teaching and learning situation through fostering and improving the teaching profession, in detail as follows: (1) Increasing the efficiency and effectiveness of teaching and learning; (2) Controlling the implementation of technical educational fields in schools in accordance with the stipulated provisions and policies; (3) Ensuring that teaching and learning activities take place in accordance with applicable regulations, so that they run smoothly and obtain optimal results; (4) Assessing the success of the school in carrying out its duties; and (5) Providing direct guidance to fix problems, shortcomings and mistakes and help solve problems faced by schools so that further errors can be prevented.
[5] states that teachers have great potential in themselves, but this potential has not been stated in full teaching activities because they have not received stimulation and motivation from supervisors as school leaders and their seniors. Principal supervision is the principal's ability to influence teachers as subordinates to be able to work together to carry out their work activities in order to improve performance by providing motivation and awareness so that teachers work fully according to their capacity. Principals are required to be able to cooperate with subordinates, in this case, of course, are teachers.
From the results of the preliminary observations that have been made, the researcher found several problems in the implementation of the principal's duties including: (1) The lack of the supervisory role of the principal given to empower school resources, especially teachers in achieving educational goals; (2) Lack of infrastructure as a support for improving the quality of education at SMA Negeri 10 OKU, so that the impact on teachers in delivering learning material is not optimal; (3) Lack of teacher professionalism in class management. Therefore, this research was carried out aimed at identifying the role of principal supervision as an effort to improve teacher teaching techniques in teaching at SMA Negeri 10 OKU.
