An investigation on theses and dissertations on mathematical modeling in Turkey in the last two decades.

Koç, Dilek
In line with the developing science and technology, mathematical modeling which links up real life and mathematics has become increasingly popular, and the number of studies conducted on mathematical modeling has increased recently. This study aimed to investigate master thesis (MS) and doctoral dissertations (Ph.D.) completed over the last two decades in Turkey to understand the portrait of mathematical modeling, by particularly focusing on the Models-and Modeling Perspective (MMP). The features and nature of modeling research that this study focused on involves level of the graduate studies (i.e., MS thesis and Ph.D. dissertations), the completion years, the university contributions, the employed research methods, the participants, the amount of the modeling research involving mathematical modeling activity, and the extent of which mathematical modeling activities reflecting the six design principles of Models-and Modeling Perspective. Data set of the study involved 70 modeling studies (MS/Ph.D.) that were published between 2000 –2019 on mathematics education field and that were gathered from the database of Higher Education Council. Document analysis and content analysis, the two qualitative data analysis methods, were utilized to investigate the features and the nature of these modeling studies. The data analysis was deepened by investigating 42 modeling studies (among 70) comprising of at least one modeling activity through a concept-driven coding frame. Consequently, it was revealed that the type of modeling studies published in the mathematics education field were mostly master thesis. The first modeling study was published in 2005 as a master thesis. The number of modeling MS and Ph.D. studies was gradually increased from 2000 to 2020, and there was a rapid increase in conducted modeling studies after 2013. Twenty-four different universities in Turkey contributed to the academic work about modeling in this field. The most used research method in modeling studies was qualitative research method which was followed by mixed and quantitative research methods, respectively. The participants of modeling MS and Ph.D. studies differed from 4th grade to 9th grade students along with pre-service teachers and in-service teachers; the major focus appeared to be on pre-service teachers. 19 out of 42 modeling MS and Ph.D. studies, almost half of them, included 3-6 modeling activities whilst the rest of 23 modeling MS and Ph.D. studies involved various number of modeling activities. With this study, it is expected to provide a portrait of the modeling studies that was conducted as MS thesis and Ph.D. dissertations in Turkey, which is hoped to be informative for researchers in mathematical modeling.


An investigation of pre-service mathematics teachers' semiotic representations and modeling routes in a mathematical modeling activity
Çetinbaş, Merve; Çetinkaya, Bülent; Department of Mathematics Education (2022-9-1)
This study aimed to examine the characteristics of pre-service mathematics teachers' mathematical modeling processes in terms of semiotic representations and the modeling routes varying within the scope of these characteristics. Participants were 13 pre-service teachers studying at a state university in Ankara and enrolled in an elective course entitled “Mathematical Modeling for Teachers.” Data were collected through a technology-integrated mathematical modeling activity. The pre-service mathematics teache...
The development of a self-efficacy scale for mathematical modeling competencies
KOYUNCU, İLHAN; Guzeller, Cem Oktay; Akyüz, Didem (2017-01-01)
Mathematical modeling has come into prominence during the last few decades in many countries' mathematics teaching curricula. It combines real life situations with mathematical context. Although evaluating students' mathematical modeling performances with a unique Likert type instrument is questionable, having an instrument about their self-efficacy beliefs in mathematical modeling may help to comment about their ideas related to their competencies in mathematical modeling. The purpose of this study is to d...
An Investigation of prospective secondary mathematics teachers’ thinking about mathematical modeling and pedagogy of modeling throughout a modeling course
Korkmaz, Himmet; Erbaş, Ayhan Kürşat; Department of Secondary Science and Mathematics Education (2014)
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 201...
Mathematical Modeling in Mathematics Education: Basic Concepts and Approaches
Kertil, Mahmut; Erbaş, Ayhan Kürşat; Çetinkaya, Bülent; Alacacı, Cengiz; Çakıroğlu, Erdinç; Baş, Sinem (2014-01-01)
Mathematical modeling and its role in mathematics education have been receiving increasing attention in Turkey, as in many other countries. The growing body of literature on this topic reveals a variety of approaches to mathematical modeling and related concepts, along with differing perspectives on the use of mathematical modeling in teaching and learning mathematics in terms of definitions of models and modeling, the theoretical backgrounds of modeling, and the nature of questions used in teaching modelin...
An Investigation of in-service secondary mathematics teachers’ evolving knowledge through professional development activities based on modeling perspective
Aydoğan Yenmez, Arzu; Erbaş, Ayhan Kürşat; Department of Secondary Science and Mathematics Education (2012)
Although an increasing number of research studies in mathematics education have begun focusing their efforts on mathematical modeling as a need for change to convey mathematical ideas beyond schools, there is not enough information about the nature of the teacher knowledge for effective use of modeling in mathematics teaching and how this knowledge evolves. The goal of this study is to investigate teachers’ evolving knowledge when they engage in professional development activities based on lesson study cycl...
