Çelik, Halil Coşkun; İlhan, Aziz; Akın, M Faysal
The aim of this study is to investigate the role of Apartment Sudoku materials in mathematics teaching on mathematical thinking and misconceptions of mathematics teachers. The study was designed as a case study model of qualitative research methods. The participants formed 52 mathematics teacher candidates studying in the second and fourth grades of a university in the Southeastern Anatolia region. The mathematical thinking skills review form and the misconception form developed by the researchers were used as data collection tools. The data were analyzed by content analysis method. As a result of the research, it was determined that the mathematics teacher candidates could acquire the characteristics of the colors in the Apartment Sudoku material, relate these properties to the problem solving and reasoning processes, in general can express the definition and properties of the misconceptions and correctly identify the misconceptions of the colors in this material. Some suggestions were made to the researcher who wanted to work in this area in the context of the findings obtained.

The aim of the present study is to examine the impact of instruction with visualization of identities in form in mathematics on students' achievement and opinions. The study employs an explanatory design, a mixed method, through which qualitative and quantitative data were collected and analysed. Quantitative data in the study were obtained using the Identities and Binomial Exponential Achievement Test to determine the effect of visualization-assisted instruction on students' academic achievement. Qualitative data, regarding the student views on the subject, were collected through a structured interview form. Participants of the study, 53 students, were selected by appropriate sampling method among the first-year univeristy students. The t-test and one-way covariance analysis were used to analyse the quantitative data and the content analysis method was used for the qualitative data. The results obtained from quantitative data indicated that instruction of algebraic expressions through mathematical visualization increased student achievement in comparison to traditional instruction. On the other hand, the qualitative data indicated that visualization facilitated a positive development in instruction of algebraic expressions, rendered the teaching process to be more interesting and enjoyable and led the students to acquire conceptual learning skills instead of memorizing.
