Argumentation is an important part of education in different disciplines such as science teaching and psychology. Numerous research studies have revealed that the use of argumentation practices in courses have a positive impact on students' both cognitive (critical thinking, reasoning, etc.) and affective abilities. Recently, the number of studies on argumentation in the field of mathematics education has increased. It is expected that prospective teachers today are key elements of the argumentation process as they can encourage students to produce strong mathematical arguments; hence, they themselves are also expected to develop their own argumentation skills. In the literature, there is a need for studies on the reasoning processes and argumentation structures of prospective teachers. Thus, the present study aimed to investigate the global argumentation structures used by prospective middle school mathematics teachers while they were solving geometry tasks. In line with this purpose, a qualitative case study was conducted with 8 prospective teachers who were enrolled in the elementary mathematics education department of a state university located in Ankara. Two argumentation applications were conducted with the participants. In the first application, two problems on triangles and in the second one two problems on circles were solved by the participants. Then, the global argumentation structures of the participants were examined. The results showed that mathematical reasoning of prospective middle school mathematics teachers was weak and, therefore, they mostly used simple global argumentation structures. On the other hand, it was found that the researcher's directions lead participants to use more complex global argumentation structures. Therefore, it was concluded that the teachers who orchestrate the argumentation process should have sufficient knowledge and experience regarding argumentation. This result revealed the importance of focusing on the development of mathematical reasoning skills of prospective teachers. Based on this, it is recommended that necessary adjustments be made in teacher training programs to include argumentation so that prospective teachers can be equipped with the ability to orchestrate argumentation in their lessons.

An investigation of prospective middle school mathematics teachers' argumentation, proof, and geometric construction processes in the context of cognitive unity Demiray, Esr; Işıksal Bostan, Mine; Department of Elementary Education (2019) The first purpose of this study is to investigate how prospective middle school mathematics teachers’ argumentation process while producing conjectures in the cognitive unity based activities relates to the proving process of conjectures they produced. The second purpose is to examine the global argumentation structures emerged while producing conjectures, the components of argumentation, and the functions of the rebuttal component. The third purpose is to investigate the approaches offered to perform geome...
How technology supports argumentation structures in the geometry context Erkek, Özlem; Işıksal Bostan, Mine (null; 2018-07-02) Argumentation encompasses higher order thinking skills, such as generating hypothesis, justifying ideas, synthesizing problems, challenging others’ views, comparing different positions and evaluating hypotheses via empirical evidence (Hewit, 2010). The teacher plays a crucial role in the argumentation process and, thus, should be pedagogically equipped to effectively prepare and implement an argumentation-based instruction. The aim of the present study was to investigate the nature of the argumentation stru...
A Metasynthesis of Research on Foreign Language Teacher Identity in Turkey: Implications for Teacher Education Taner, Gülden; Karaman, Abdullah Cendel (2013-12-01) This study explores main areas of research and identifies patterns that help interpret current tendencies in the literature on aspects related to language teacher education. For this purpose, we report the outcomes of a metasynthesis of 44 studies related to teacher identity. Conceptually, the analysis is guided by how teacher identity is framed. The structured searches in relevant databases led to conducting a particular type of systematic review known as template analysis. As a result, based on the inter...
A Longitudinal Study on Mathematics Teaching Efficacy: Which Factors (Un)Support the Development? Işıksal Bostan, Mine (2016-08-01) The aim of this longitudinal study was to examine prospective teachers' mathematics teaching efficacy belief during their enrollment in teacher education program and at the end of their first year of teaching. In addition, the factors that enhance or inhibit participants' efficacy belief and how these factors affect their mathematics teaching efficacy when they become inservice teacher were investigated. Mixed research design was used in which data were collected through longitudinal survey and electronic i...
The Role of argumentation theory in scientific reasoning and science education Meriç, Gülden Alaz; Zambak, Aziz Fevzi; Department of Philosophy (2019) This thesis analyzes Argumentation Theory within the context of science education. Within this thesis’s purpose, foundations of Argumentation Theory together with the theory’s main elements are also explained. The role of Argumentation Theory is approached in two aspects, namely the philosophical aspect and the educational aspect. In the philosophical aspect, it is questioned whether some reformations in Argumentation Theory is needed for adapting it for science education. In the educational aspect, it is e...
