Abstract
In this study, teacher learning and its special place in mathematics teaching were examined. For this purpose, an analysis of the studies on what teacher learning means and how it is developed in both national and international literature has been analyzed. As a result of the analysis, it was noted that the number of national studies on teacher learning is quite low. Within the framework of the researches, it was determined that teacher learning, which is one of the professional development components, is an important component of professional development and systematic steps should be followed for its development. In addition, it has been revealed that the reflection of the changes in the teacher's beliefs, attitudes and behaviors of well-planned teacher learning programs into the classroom will result in a positive change in student learning. Finally, the researchers who are interested in the subject find it more beneficial to carry out update studies in each country's own conditions, rather than the international adaptation studies of the models developed by the countries for teacher learning.
