İlköğretim matematik öğretmen adaylarının matematikselleştirme sürecinin bir matematiksel modelleme etkinliği süresince incelenmesi.

The purpose of this study was to investigate pre-service mathematics teachers’ mathematization process in a mathematical modeling activity. The process was investigated in two different levels of mathematization based on Realistic Mathematics Education (RME) framework namely, horizontal mathematization and vertical mathematization. This study designed as a case study. The participants of the study were six pre-service elementary mathematics teachers enrolled in a course entitled “Mathematical Modeling for Teachers”. One of the activities covered in the course was about the real life situations emerged in the context of Ferris wheel and selected for this study. The participants worked on the activity in groups of three. The source of data comprised of reflection papers written by the participants, transcription of videotapes during the group discussions, group presentations and worksheets. The results of this study revealed that during both horizontal and vertical mathematization process, pre-service teachers had difficulties and misconceptions while understanding the problem, determining the independent variable of the function and forming the function.M.S. - Master of Scienc
