Examination of secondary school mathematics teachers' feedbacks used in lesson processes according to grade levels

In this study, it was aimed to determine the types of feedback that middle school mathematics teachers use in their classroom settings and how these feedbacks differ according to grade level. The study was carried out in the second term of 2018-2019 academic year and in the first term of 2019-2020 academic year by using the special case method, which is one of the qualitative research methods. The research was carried out with three mathematics teachers working in the same public school in the district of Kaynarca, Sakarya. As the data collection tools, the observation form prepared on the basis of the feedback classification by Tunstall and Gipps(1996) translated into Turkish by Kögce (2012) and the video recordings in which the lessons were observed were used. The data set of the study consists of a total of 32 class hours recorded by three mathematics teachers' cameras. The data obtained from a total of 32 lesson hours, 8 lessons per class, were analyzed with a content analysis approach. According to the findings of the research, it was concluded that middle school mathematics teachers used both evaluative and descriptive feedback to a certain extent, and the most frequently used feedback categories were positive evaluative feedback and development-related feedback. It was seen that the most used type of feedback from evaluative feedback was approval, and punishment feedback was almost never used. It was seen that the most frequently used feedbacks from descriptive feedback form the development path and indicate the improvement. As a result of the research, the preferences of middle school mathematics teachers to use evaluative feedback in 5th and 6th grades tended to descriptive feedback in 7th and 8th grades.
