Abstract
Co-teaching as an innovative method is being given increasing attention in the international environment, especially through realized experiments. The main orientations of education policy with a view to the next decade include, inter alia, promoting educational innovation and verifying it through further professional development of teaching staff and exploring the effectiveness of learning. One of the possibilities of achieving this goal is co-teaching and its forms, which are constantly evolving. Inductive thematic analysis identified six themes: (1) "co-teaching effectiveness", (2) "problems and obstacles", (3) "methods of and with co-teaching", (4) "teachers' roles and relationships", (5) "teachers' cooperation", and (6) "special educational needs" (SEN).
