The activity model carried out is mentoring with the lecture approach, discussion, peer and tutor feedback and assignments. Evaluation of activities is carried out by administering tests and questionnaires as well as monitoring and documenting articles produced by the teacher. The findings of the evaluation demonstrated that the enthusiasm, knowledge, and skills of teacher participants in writing scientific articles increased.
