“…It was concluded that mainstreaming education could not be realized as desired due to reasons such as the physical structure of the school and the unsuitable class size, the unequal distribution of inclusion students to the classes, the demands of the classroom teachers not being met, insufficient material support, and insufficient inservice trainings despite the fact that the teachers received assistance from the training support teachers (Sarac and Colak 2012;Guzel 2014;Yaman 2017). When the studies were examined in general, it was found that classroom teachers emphasized that they did not find themselves sufficient about inclusion education, that support education services and material support were not provided, and that they wanted to improve themselves in relation to the education of students with special needs but they did not receive education support in this sense (Dagli and Oznacar, 2015;Germano, Brito and Capellini, 2017;Sardohan and Akcamete, 2018;Bayrakli and Sucuoglu, 2018). In order to be effective in mainstreaming education, it is of great importance to determine the actions of classroom teachers regarding instructional practice and evaluation, and to take necessary precautions and to provide the necessary support in this area.…”
