    Assessment of student achievement and views on the impact of instruction with visualization of identities in (ax+b)n form in mathematics
    (Pegem Akad Yayincilik Egitim Danismanlik Hizmetleri Tic Ltd Sti, 2018) Ilhan, Aziz; Celik, Halil Coskun
    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.

    What is the Predictive Power of Visual Mathematics Literacy Perception and Its Sub-dimensions for Geometry Success?
    (Ani Yayincilik, 2019) Ilhan, Aziz; Tutak, Tayfun; Celik, Halil Coskun
    Purpose: In this study, it was aimed to examine the relationship between the visual mathematics literacy perceptions and its sub-dimension for geometry success levels of prospective teachers. It was also aimed to examine to what extent visual mathematics literacy perception and its sub-dimensions predicted geometry success. Research Methods: This study was designed in accordance with a qualitative, scanning model. The research was carried out with 232 (97 males and 135 females) prospective teachers who studied in Mathematics Education Program at Firat University, Education Faculty, and were selected by simple random sampling method. Visual Mathematics Literacy Perception Scale and Geometry Success Literacy Perception Scale and Geometry Success Test were employed in this study as data collection tools. Correlation analysis and multiple regression analysis were used for analyzing the data. Findings: After the data were analyzed, it was determined that there was a positive relationship between the visual mathematics literacy perception and geometry success of prospective teachers. It was also determined that visual mathematics literacy perception is a meaningful predictor of geometry success. Implications for research and practice: Providing trainings on these concepts in the direction of the results, to investigate the concept of perception on other learning areas of mathematics and conducting experimental studies on the perception of visual mathematics literacy are suggested.
