ABSTRACT Adopting a multitiered design-based research perspective, this study examines pre-service secondary mathematics teachers’ developing conceptions about (a) the nature of mathematical modeling in simulations of “real life” problem solving, and (b) pedagogical principles and strategies needed to teach mathematics through modeling. Unlike other studies that have focused on single-topic and lesson-sized research sites, a course-sized research site was used in this study. Having been through several iterations over three teaching semesters, the 15-week long course was implemented with 25 pre-service secondary mathematics teachers. Findings revealed that pre-service teachers developed ideas about the nature of mathematical modeling involving what mathematical modeling is, the relationship between mathematical modeling and meaningful understanding, and the nature of mathematical modeling tasks. They also realized the changing roles of teachers during modeling implementations and diversity in students’ ways of thinking. The researchers’ conceptual development, on the other hand, involved realizing the critical aspect of the “teacher role” played by the instructor during modeling implementations, and the need for more experience of modeling implementations for pre-service teachers.

The purpose of this study is to investigate the evolution of prospective secondary mathematics teachers’ thinking about mathematical modeling and pedagogical knowledge of mathematical modeling throughout a modeling course designed for teachers. This study utilizes case study as a research design. The participants were 25 prospective secondary mathematics teachers enrolled in a course entitled “Mathematical Modeling for Prospective Teachers” in a public university, in Ankara during the spring semester of 2011-2012. Data were collected through six modeling activities, participants’ working sheets on the modeling activities, pre- and post-survey forms related to pedagogy of modeling, semi-structured interviews, field notes, videotaped classroom discussions, classroom observation notes, and students’ way of thinking sheets. The data were analyzed by using qualitative methods. The results of the study demonstrated that prospective teachers developed positive views about mathematical mode...
