The Learning study could be considered as a form of teacher research aiming at understanding and improving practice and building theory. It is focused on the development of teaching-learning units, guided by a theoretical framework –variation theory and aims to accomplish the learning of specific objects of learning. The knowledge product is designed to help the professionals to solve problems with teaching and learning they encounter in their everyday practice. Hence, it is more connected to professionals’ tasks than to professionals. Just like the Lesson Study it creates joint and shareable knowledge products in terms of lesson plans which could serve as a resource for other teachers. A significant feature of the Learning Study is however, its possibility to theoretically describe the results of the specification process regarding objects of learning within different subject matter areas (Carlgren, 2012). In the presentations we will deal with issues about the knowledge products of the Learning study as well as Learning study as teacher research.
