Lecturers are people with professional qualifications, carrying out teaching or specialized training at a high level above the general level. Lecturers often work at colleges, universities or secondary schools. They are people with specialized knowledge, in-depth study of a certain specialty or field of work.

This is the first role that needs to be affirmed for teachers. The self-study of non-formal learners easily distorts the lesson content, basic knowledge and heterogeneous thinking if the lecturer does not orient the students. The lecturer will play the role of orienting the subject content as well as orienting the content of each lesson for students. On the basis of the lecturer's orientation, the students' self-study focuses on solving the basic content of the subject as well as achieving the objectives of the subject and each lesson. The orientation of the lecturers is related to the content of group study, discussion, lesson preparation and exchange among learners. The lecturer orients how to exploit the content, orients the knowledge of the lesson as well as orients the thinking for each problem. Orientation is a factor that promotes self-study. Orientation helps learners stay on the right track.
