The purpose of this study is developing valid and reliable scales in order to measure beliefs and perceived self-efficacy beliefs towards using origami in mathematics education and then, investigating beliefs and perceived self-efficacy beliefs of Turkish prospective elementary mathematics teachers in using origami in mathematics education. Furthermore, gender differences in prospective teachers&#039 / beliefs and perceived self-efficacy beliefs in using origami in mathematics education were investigated. Data for the current study was collected in the spring term of 2011-2012 academic year from 299 prospective elementary mathematics teachers. These teacher candidates are from three universities located in three different regions of Turkey and all the participants have elective origami course experience. Origami in Mathematics Education Belief Scale (OMEBS) and Origami in Mathematics Education Self-Efficacy Scale (OMESS) were used as data collection instruments. Exploratory and confirmatory factor analysis results showed that OMEBS and OMESS are valid and reliable instruments in order to measure beliefs and perceived self-efficacy beliefs in using origami in mathematics education. Descriptive analysis results indicated that, Turkish prospective elementary mathematics teachers strongly believe that origami is beneficial and suitable to be used in mathematics education. However, their perceived self-efficacy belief level is at little higher than moderate level. Lastly, independent sample t-test results revealed that female teacher candidates have significantly higher belief and perceived self-efficacy beliefs in using origami in mathematics education when compared with male teacher candidates.

The aim of this study is to investigate perceptions of preservice mathematics teachers&rsquo / technological pedagogical content knowledge (TPACK) regarding geometry. In addition, the purpose is to examine the relationships among the components of TPACK. Moreover, possible gender and year of enrollment differences related to preservice mathematics teachers&rsquo / technological pedagogical content knowledge dimensions are examined. This research study has been conducted with 780 preservice mathematics teachers who are enrolled in elementary mathematics education department of Education Faculties of seven public universities located in Central Anatolia. Perceived TPACK regarding geometry instrument has been developed to collect data. In order to determine the levels of preservice mathematics teachers&rsquo / perceptions related to TPACK in geometry, descriptive information have been used. The results indicate that preservice mathematics teachers&rsquo / perceptions of TPACK related to geometry is higher than moderate. Furthermore, correlational analysis was conducted to identify the relationship among dimensions of TPACK. Positive significant correlations among the components of the TPACK framework were found in correlational analysis. Besides, two-way MANOVA has been conducted to investigate a possible relationship between demographic information of preservice elementary mathematics teachers and their perceptions of TPACK. According to the MANOVA results, there are statistically significant differences between male and female preservice mathematics teachers in favor of male participants in three components of TPACK, namely technological knowledge, technological pedagogical knowledge and technological pedagogical content knowledge in favour of males.

The purpose of this study was to examine elementary teachers&rsquo / and elementary mathematics teachers&rsquo / perceptions of mathematically gifted students in terms of teachers&rsquo / gender, year of experience and area of teaching. The data were collected from 176 elementary teachers and 90 elementary mathematics teachers from 60 state elementary schools in the center of Trabzon, in the fall semester of 2011-2012 academic year. In order to determine teachers&rsquo / perceptions of mathematical giftedness, the instrument called as Teachers&rsquo / Judgments of Gifted Mathematics Student Characteristic (TJGMSC) was used. The results were evaluated in terms of three dimensions of TJGMSC: school smart mathematics student, mathematics perspective for the real world and creative problem solver. Besides, in order to analyze the data, one-way MANOVA was conducted. The results of the study illustrated that there were no significant differences among teachers&rsquo / TJGMSC scores, in terms of their gender and year of experience. However, a significant difference was found between elementary teachers and elementary mathematics teachers in terms of their TJGMSC scores for only the dimension of school smart mathematics student. To illustrate, elementary teachers&rsquo / scores regarding this dimension were higher than those of elementary mathematics teachers.

This study analyzes the kinds of beliefs pre-service elementary mathematics teachers hold about mathematical problem solving, and investigates whether, or not, gender and university attended have any significant effect on their problem solving beliefs. The sample of the present study consisted of 244 senior undergraduate students studying in Elementary Mathematics Teacher Education programs at 5 different universities located in Ankara, Bolu, and Samsun. Data were collected in spring semester of 2005-2006 academic years. Participants completed a survey composed of three parts as demographic information sheet, questionnaire items, and non-routine mathematics problems. The results of the study showed that in general the pre-service elementary mathematics teachers indicated positive beliefs about mathematical problem solving. However, they still had several traditional beliefs related to the importance of computational skills in mathematics education, and following predetermined sequence of steps while solving problems. Moreover, a number of pre-service teachers appeared to highly value problems that are directly related to the mathematics curriculum, and do not require spending too much time. Also, it was found that although the pre-service teachers theoretically appreciated the importance and role of the technology while solving problems, this belief was not apparent in their comments about non-routine problems. In addition to these, the present study indicated that female and male pre-service teachers did not differ in terms of their beliefs about mathematical problem solving. However, the pre-service teachers&rsquo / beliefs showed significant difference when the universities attended was concerned.

The purpose of this study was to identify and describe elementary and mathematics teachers&rsquo / views about the new elementary school mathematics curriculum (NC). A total of 22 elementary teachers (grades 1-5) and mathematics teachers (grades 6-8) Alaca district of &Ccedil / orum participated. The data were collected through one-to-one interviews with some of the participants and written responses for the interview questions provided by the rest of the participants. The findings indicated that the participants had positive views about the impact of the NC. Participants reported that the NC helped students reach meaningful learning through the instructional activities, new content, curriculum materials, and new assessment techniques. Participants had positive views about the new roles for the teachers and the students and the increased student motivation that the NC brought. They also expressed challenges in teaching due to the lack of materials, physical facilities, and time. Local differences impacted the implementation of the NC negatively in rural contexts. The intensity of the NC made instructional activities and the assessment processes difficult to implement in multi-grade and crowded classrooms. Participants did not feel efficient enough to implement the NC since they lacked adequate training and support. While teachers adopted the ideas that the NC brought, they adapted these practices to their existing practices. They reported performing a combination of NC practices and previous practices. Participants claimed that content of Ministry support should be more practice oriented, the curriculum materials should be sufficient in number, and the duration of mathematics lesson should be increased.

The main purpose of the study was to understand preservice secondary mathematics teachers&rsquo / pedagogical content knowledge of composite and inverse functions. The study was conducted with three preservice secondary mathematics teachers in Graduate School of Education at Bilkent University. The instruments of the study were qualitative in nature and in four different types of data forms: observations, interviews, documents, and audiovisual materials. Observation data came from fieldnotes by conducting an observation of lessons participants taught at Private Bilkent High School. Interview data came from the transcriptions of semi-structured interviews. Document data came from survey of function knowledge, journal writings, vignettes, and lesson plans. Audiovisual data came from the examination of the videotape of the lessons participants taught. The findings reveal that preservice secondary mathematics teachers&rsquo / knowledge levels in components of pedagogical content knowledge were not at the desired levels and also they experienced difficulty while integrating that knowledge. The results of the study indicate that teacher education should provide courses that cover the content relevant to students in order to assure both depth and breadth in subject matter knowledge of the preservice teachers. Moreover, the activities which mimics the classroom cases and assures the integration of knowledge components like vignettes would be used in teacher education programs. Results can inform educational practices, and reforms in Turkey, and provide a basis for further research, with increased pedagogical content knowledge as the ultimate goal.

The current study seeks to investigate pre-service elementary mathematics teachers&rsquo / (PEMTs&rsquo / ) self-regulated learning (SRL) strategies within the context of their teaching practices in the field work. It was aimed to explore the SRL processes and strategies of four PEMTs while preparing mathematics lessons at their practice schools. In addition to PEMTs&rsquo / SRL strategies, the changes and adaptations through their teaching practices and reasons of those changes were also examined in the study. In total 22 pre-interviews and 22 post-interviews were made through the study. Observations were also performed for each teaching practice. Besides observations, PEMTs&rsquo / end of semester reflection papers in the context of Teaching Practice course were examined in the study. In addition to those multiple data sources, initial interviews representing detailed information about the participants were also analyzed. The overall data were analyzed by using the SRL framework combined and adapted from Zimmerman&rsquo / s and Pintrich&rsquo / s SRL models. The findings of the pre-interviews revealed that PEMTs began with a &lsquo / lesson planning process&rsquo / reflecting the forethought phase. This phase included searching resources, arranging and organizing the available sources, asking for help and feedback when needed, mental planning of the lesson, and setting goals for the teaching session. These strategies were considered as cognitive self-regulation strategies. In addition to cognitive SRL strategies, motivational factors such as self-efficacy, perception of task, and intrinsic interest were appeared in the study. Post-interviews reflecting the self-reflection phase revealed that PEMTs had a self-evaluation process covering various issues for their teaching sessions as a final step through the study. Finally, it was seen that contextual issues related to teaching practice played a substantial role in PEMTs&rsquo / SRL strategies.

The purpose of this study is to construct a valid and reliable mathematics related beliefs scale for determining preservice elementary mathematics teachers&rsquo / mathematics related beliefs in Turkey and investigating the impact of the gender and year level on the preservice mathematics teachers&rsquo / mathematics related beliefs. For the first purpose, the &ldquo / Mathematics Related Belief Scale (MRBS)&rdquo / was developed based on the combination of the belief frameworks in the literature. Data were collected from ten different universities from Ankara, Balikesir, Burdur, Bolu, Gaziantep, Izmir, Van, and Samsun in the spring semester of 2009-2010 academic year. A total of 584 third and fourth year preservice mathematics teachers participated in this study. Data were analyzed by descriptive and inferential statistics. The results showed that MRBS was a valid and reliable scale which measured Turkish preservice teachers&rsquo / mathematics related beliefs. MRBS had two components &ldquo / constructivist beliefs&rdquo / and &ldquo / traditional beliefs&rdquo / of mathematics and teaching mathematics. There was a significant effect of gender on preservice teachers&rsquo / mathematics related beliefs. No significant difference in preservice teachers&rsquo / mathematics related beliefs was detected in terms of year level in the teacher education program. The MRBS could be used for investigating preservice teachers&rsquo / mathematics related beliefs in order to determine effective teacher education program experiences.

The current study aimed to explore middle school mathematics teachers&rsquo / use of mathematics textbooks and examine their integration of tasks in the textbooks into teaching. The framework of a mixed methods research design guided data collection in this study. A questionnaire called the Use of Mathematics Textbooks Questionnaire was developed and validated to identify the ways teachers benefit from textbooks. The factor analysis revealed four dimensions, namely Reading Student Edition Textbook, Selecting Questions from Workbook, Reading Teacher Edition Textbook, and Selecting Tasks and Problems from Auxilary Books. The results of the study showed that teachers used the student edition textbook for mostly during class and for lesson preparation. Teachers also used the student edition textbook for explaining the topic and the introductory tasks. However, they rarely used it for selecting problems and examples. Teachers read the student edition textbook mostly during and prior to class / and mostly use it for topic explanation, but rarely for problems and examples. They stated that they frequently selected questions from the workbook that were not included in the textbook. However, they occasionally picked questions to use during lessons. They frequently used auxilary books to select questions similar to the ones in the high school entrance exam problems. In examining the process of teachers&rsquo / use of mathematics textbooks, it was argued that there were interpretive processes as teachers engage with and use textbooks. The analysis of interviews and observations showed that teachers read textbooks and select tasks and questions from those books. In their decisions about using tasks from textooks, teachers usually considered the nature of tasks and students&rsquo / characteristics.

M. Tech. Business Information Systems / Information technology (IT) rapidity, and the pervasive implementation of new technologies in the education system, has tremendously improved the way teaching and learning is conducted. Institutions are being reshaped by the rapid provision of education services anytime, anywhere regardless of the constraint of space and geographical boundaries. This has enhanced collaboration among educators as well as their learners by sharing and disseminating of knowledge. However, this sharing of knowledge is still limited as educators have not fully exploited IT to share knowledge. The major objective of this study was to develop a framework for utilizing IT to enhance knowledge sharing for mathematics and science teachers.
