The aim of this study was to explore the degree to which a professional development (PD) program designed using GeoGebra influences a group of Turkish middle school teachers’ beliefs in relation to mathematics and role of GeoGebra in mathematics education. In order to collect the required data, the PD course was established to provide six teachers with an opportunity to obtain practical experiences with and necessary knowledge about the use of GeoGebra in mathematics education. In this context, a multiple case study approach was utilized, in which mathematics teachers were observed and interviewed using a variety of procedures to expose qualitative data about their beliefs and the dynamics of their beliefs changes during the course. The main findings illustrated that teachers’ beliefs were transformed to some extent in favour of the use of GeoGebra, as well as using constructivist ideas in their mathematics teaching and learning can be attained through the GeoGebra based PD course. In fact, the relationship amongst stated beliefs and intended teaching practice is complex and the social issues were very influential on teachers’ pedagogical decisions. This research also introduces some suggestions for researchers who focus on professional development of mathematics teachers relative to their beliefs..

In this study, in-class lesson observations were made with volunteer teachers working in primary and secondary schools using alternative observation tools regarding the scope of contemporary educational supervision. The study took place during the fall and spring semesters of the 2015-2016 and 2016-2017 academic years and the class observations were made with six alternative volunteer teachers in the primary and secondary schools in the provincial and district centers using alternative observation tools. In the classroom observations, the teacher's verbal flow scheme, teacher's movement scheme and student behaviors both during tasks and not, were analyzed. Observations were made during the two classes with teacher's permission. After the first observation, an information meeting was held and then the second observation was made. Following the observations, interviews were held with the teachers. In interviews, the information about the class observations was shared with teachers and their opinions about research were asked. It has been found that alternative observations, in general, have a positive effect on the professional development of teachers. It is concluded that this type of observation approach positively affects teachers' in-class activities, helps in classroom management and teaching arrangements and positively affects student's unwanted behaviors.

This study aims to explain the extent to which prospective physics teachers’ views and practices are consistent with the constructivist framework. A case study design was employed as the research approach. The study was conducted with 11 prospective physics teachers attending a state university in Turkey. Data was collected through semi-structured interviews, observation notes and lesson plans. The interview guide consisted of questions which allowed the interviewer to probe participants’ views of constructivism based on 5E learning model. Such questions as “how do you plan your teaching?” (introducing new topics, continuing the lecture, types of questions to ask, evaluating students’ understanding etc.) were included in the interview. Following the analysis of the interview data, participants’ profiles were classified into three categories: traditional, transition and constructivist under the dimensions “beginning of a lesson,” “learning process,” “learning environment” and “assessment.” Observations were carried out using an observation checklist consisting of 24 items based on 5E learning model. Another checklist developed by the researchers was used to evaluate participants’ teaching qualifications. Interview results showed that seven participants had transitional, three had constructivist and one had traditional views. However, none of the participants were observed to exhibit constructivist teaching styles. Moreover, observation and interview results were consistent only for six participants, indicating that almost half of the participants had difficulty putting their views into practice.

It is important for pre-service teachers to know the conceptual difficulties they have experienced regarding the concepts of multiplication and division in fractions and problem posing is a way to learn these conceptual difficulties. Problem posing is a synthetic activity that fundamentally has multiple answers. The purpose of this study is to analyze the multiplication and division of fractions problems posed by pre-service elementary mathematics teachers and to investigate how the problems posed change according to the year of study the pre-service teachers are in. The study employed developmental research methods. A total of 213 pre-service teachers enrolled in different years of the Elementary Mathematics Teaching program at a state university in Turkey took part in the study. The “Problem Posing Test” was used as the data collecting tool. In this test, there are 3 multiplication and 3 division operations. The data were analyzed using qualitative descriptive analysis. The findings suggest that, regardless of the year, pre-service teachers had more conceptual difficulties in problem posing about the division of fractions than in problem posing about the multiplication of fractions.

The object of this study is to determine the conceptual understanding that prospective Science teachers have relating "de Broglie: Matter waves" and to investigate the effect of the instruction performed, on the conceptual understanding. This study was performed at a state university located in the western part of Turkey, with the Faculty of Education-Science Teaching students (2nd year / 48 individual) in the academic year of 2010-2011. The study was planned as a single group pretest-posttest design. A two-step question was used in the study, prior to and after the instruction. Lessons were conducted using the 7E learning model in the instruction process. When all these results are evaluated, it can be said that the conceptual understanding of the prospective teachers regarding "de Broglie; matter waves" has been taken place. In general, when all the sections are examined, it has been observed that the prospective teachers have more alternative concepts prior to the instruction and more scientific concepts after the instruction.  In this process, besides instruction, the prospective teachers have not taken any place in a different application regarding the basic concepts of quantum physics. Therefore, it has been determined that the 7E learning model used in the research and the activities included in the 7E learning model are effective in conceptual understanding.

The purpose of this study was to investigate the effect of lessons conducted in out-of-school learning settings on 5th graders science achievement within the scope of a guidance material that was prepared to be used in out-of-school learning settings in accordance with the “Let’s Solve the Riddle of Our Body” chapter objectives. The pretest / posttest equalized control group design, which is one of the quasi-experimental designs, was used in this study. The sample of this study was composed of a total of 31 5th grade students (15 were in experimental group, 16 were in control group) that were selected from secondary schools in the first semester of the 2015-2016 academic year in Tokat Province. Let’s Solve the Riddle of Our Body Chapter Achievement Test (LeSROBAT) was administered before and after the implementation of the guidance material to measure the students’ achievements and retention. The lessons were conducted as suggested by the current curriculum in the control group. The data were analyzed using independent samples t-test and covariance analysis (ANCOVA). As a result of the analyses, it was found that the LeSROBAT post-test scores of experimental group were significantly higher than the control group. Within this context, it was concluded that the out-of-school learning settings positively contributed to academic achievement and the guidance material that was developed within the scope of this study was effective. The results of retention test analyses didn’t reveal any significant difference between the posttest and retention test scores of experimental and control groups. When the LeSROBAT retention test scores were examined, it was observed that the scores of experimental group was higher than the control group.

In this research, it is aimed to study the correlations between perceived supervisor supports (PSS), organizational identification (OI), organizational citizenship behavior (OCB), and burnout of teachers. The research was conducted from the perspective of social change and identity theories. The study group of the research consists of 234 teachers working in the public high schools in Giresun city center during the 2016. In order to collect data in the research, Perceived Supervisor Support Scale developed by Kottke & Sharafinski, Organizational Identification Scale developed by Mael & Ashforth, Organizational Citizenship Behaviors Scale developed by DiPaola, Tarter & Hoy, and "Burnout Scale" developed by Pines were used. The correlations between variables are tested with the structural equation model. According to the results, PSS positively affects the OI and OCB and negatively affects the burnout. OI positively affects the organizational citizenship behavior and negatively affects the burnout.  OI plays a partial mediation role in the correlation between PSS of teachers and their OCB and burnout level. The results contribute to the integration of social change and social identity theories in description of organizational behavior.

The aim of this qualitative case study is to investigate prospective mathematics teachers’ subject matter knowledge of the underlying concepts of standard and nonstandard algorithms used to solve the problems with whole numbers. Twenty three prospective mathematics teachers enrolled in the Elementary Mathematics Education Program of one of the most successful universities in Turkey were the participants of the study. The data was collected through four tasks containing basic algorithms. More specifically, the Ones Task assessed participants’ understanding of the underlying place value concepts of standard algorithms. The Andrew Task and the Doubling Task required participants to conceptualize and interpret nonstandard strategies. In the Division Task, participants were expected to provide in-depth explanation for the difference between multiplication and division and between partitive division and measurement division. The content analysis method was used to analyze the data. The results of the study revealed that more than half of the prospective mathematics teachers had knowledge about the place value of 1 in addition and subtraction, and also multiplication. However, most of the prospective teachers could not explain the underlying principle and the meaning of the nonstandard algorithm in subtraction. Similar to their knowledge on subtraction, prospective teachers’ knowledge on division was limited.

Within the scope of restructuring the secondary education efforts of the Ministry of National Education, it has been decided to abrogate the secondary school level teachers' schools. The purpose of this study is to evaluate Turkey's teacher education practices and the quest for qualified teacher education through the perceptions of the graduates of these high schools. The study is a phenomenological research based on interpretation. Data were obtained through interviews. The data obtained were analyzed in the vetting of candidate teachers, the curriculum to be used in the education process and its accreditation, and whom to be certified as teachers. The main results of this study, conducted with participants from the secondary school level teachers schools’ graduates, show that, in terms of teacher education, teachers' high schools present various opportunities by enrolling successful candidates, educating them as leaders, preparing them for multi-cultural environments. In order to educate qualified teachers, the participants suggest teacher education programs should include individual and group activities, involve training, arts, basic science, and values education courses. In the selection and approval of tenure teacher, besides academic achievement and diploma, advanced communication skills, patience, confidence, and patriotism should be sought in the candidates.

The effectiveness of schools, that is, their ability to achieve their pre-determined goals depends on many variables but especially the effectiveness of the administrators who are responsible for the implementation of the educational programs and curricula. An administrator must have a healthy perception of being "an effective administrator" in order to be able to demonstrate expected roles successfully. Concerning school effectiveness, in addition to the emphasis of self-efficacy of administrator, the leadership role of the educational administrators has gained importance with modern educational administration approaches. If an administrator wants to be effective, he/she must act as a leader and convince followers. In this context, when questioning the effectiveness of schools, it is important to determine the level of self-efficacy perceptions of administrators and to determine the leadership styles displayed by them. In this study, it was aimed to examine whether there is a significant relationship between the perceived self-efficacy belief and leadership style. The results show that self-efficacy perceptions of the administrators make a difference in their leadership style and there is a relationship between the self-efficacy belief and exhibitors of transformational leadership behaviors; the more administrators feel themselves efficient, the more they exhibit transformational leadership behaviors.

This study aims to evaluate elementary school math teachers' self-efficacy beliefs about classroom management. With the aim of investigating elementary school math teachers' self-efficacy beliefs about classroom management, a classroom management self-efficacy scale was developed.  The 5 point likert scale is composed of 46 items. The scale was applied to 142 math teachers working at elementary schools in Diyarbakir central district. Data were analyzed in terms of gender, seniority, classroom population and weekly course load. To analyze the data, t-test, one way variance analysis (ANOVA), Scheffe and LSD tests were used. The results showed that the math teachers have a positive self-efficacy belief of classroom management and that male teachers are better at maintaining discipline in class. In addition, the research shows that teachers with more experience are better at course design and classroom management and that classroom population has an effect on math teachers' self-efficacy beliefs about classroom management.

The study investigates the views of social studies teachers (SSTs) about the advantages and challenges of interactive whiteboard application in social studies lessons. Data was gathered using a questionnaire consisting of 58 items. The sample comprised 483 male and female SSTs from different governorates of Oman who were provided with three training programs about using Interactive Whiteboard (IWB). Data were analyzed by using: Means, T-test and One Way ANOVA.  The results indicated that they considered its effect to be significant in supporting students’ learning process by enhancing the quality of learning environment, excitement of use and importance of use in social studies lessons. It also showed that they used it widely in their lessons but they experienced moderate challenges, including related to technical support and the availability of IWB in all classes. The results also indicated that teachers’ gender and experience influenced their views. The study recommends the provision of more technical support to teachers.

Firstly, the researcher provides an insightful introduction into the phenomenon focused on to explicate the learners’ views about the role of school counselors in line with career selection. To attain the study objectives, the researcher used a multi-unit case study to investigate the perceptions among high-school students about school counselors’ roles and career selection. The investigator used open-ended questionnaires to harness information and then utilized the qualitative descriptive approach to analyze the data. Analysis of the information collected via open-ended questionnaires was done through thematic analysis, which was a subset of the broader qualitative descriptive technique. The findings denoted that high-school learners have varied perceptions with regards to the roles of school counselors and career selection.

This study aims to conduct validity and reliability analysis of Organizational Structure Scale-University version (OSS-U) that enables us to determine organizational structures of universities. The scale was developed based on the Axiomatic Theory by Hage, literature review and expert opinions. The sample of the study consisted of a total of 655 faculty members working at state universities in Turkey. Psychometric features of the scale were tested with three different models. The content validity of the suggested models was tested with Lawshe Analysis; the construct validity with Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) while the reliability was tested with Cronbach alpha which is a measure of internal consistency. As a result of the analyses conducted, all of these three models were determined to be valid and reliable with the relevant sample. It was also revealed that OSS-U can be used as model 1 in which nine dimensions (number of occupational specialties, professional training, professional activities, participation in decisions, hierarchy of authority, standardization, professional latitude, difference in rewards and difference in status) describe one single concept (University Structure), or model 2 in which four subscales (Complexity Scale, Centralization Scale, Formalization Scale and Stratification Scale) are independent pieces of an umbrella term (University Structure) or model 3, as a combination of these two models (model 1 + model 2), where combined subscales that have dimensions in itself describe a hypernym (University).

This study was designed as a case study. Participants were 12 senior pre-service science teachers (PSTs), who took theoretical and practical courses about STEM education and socio-scientific issues (SSIs) during their education at a state university. For the study, in the first 4 weeks, theoretical courses on SSIs and STEM education were carried out. Afterwards, PSTs were asked to choose a SSI and configure this issue as a problem statement to perform a STEM activity. Participants were given a total of 3 weeks to determine the issue and prepare the STEM activity, and the researchers of the study gave systematic feedback during this period. Then, starting from the fifth week of the study, groups started to implement their STEM activities in the class, where their peers were assigned as their students. The activity plans they prepare, the field notes taken by the researchers during the implementation of the activities and the semi-structured interviews about the opinions of the PSTs on the use of SSI in STEM education were the data sources of the study. Findings revealed that PSTs found establishing STEM problem situations over SSIs suitable since they provide features such as conformity to real life, having multiple criteria and providing compatibility with other disciplines. Moreover, after their practices, they pointed out that the activities enabled both the teaching of the SSI and the integrated teaching to be carried out. As a conclusion, it is recommended to use socio-scientific problem situations to perform STEM education.

The aim of the research is to determine the perceptions of the preservice science teachers about the photosynthesis and to reveal the relation between these perceptions and the misconceptions of the existing concepts. In the research, field scanning method was used as a descriptive research method. The sample of the research is composed of 355 preservice science teachers trained in different universities. For the selection of the sample, purposeful sample selection was used and attention was paid to the fact that the preservice science teachers had taken the General Biology-I and General Biology-II courses at the undergraduate level in the determination of the class level to be included in the study. The "Photosynthesis Concept Achievement Test" (PCAT) developed by the researcher and composed of 4 questions was used as a data collection tool. Quantitative data obtained from the study were analyzed using SPSS.20 package program while content analysis was performed in the analysis of qualitative data. As a result of the research, it was determined that the preservice science teachers' perceptions of photosynthesis were in the direction of chemical and biological approaches and that the teacher candidates preferred the chemical approach rather than the biological approach. However, preservice science teachers who prefer the chemical approach have reached the conclusion that they are in much more misconception than the biologically approaching teacher candidates.

Human Resource Management (HRM) includes recruitment, training, development, motivation and evaluation of the staff who will achieve the goals of the organization and perform the necessary activities to be successful. The success of the organization depends on the effective use and management of human resources. Considering that The Ministry of Turkish National Education has the most crowded personnel and the potential of leading the future human resources, the HRM strategies of this organization becomes significant.  In this study, it is aimed to investigate to the human resources management practices of the Ministry of Turkish National Education from the perspectives of teachers who are also the human resources of the system.  In this research, holistic-multiple case study design was employed and the open-ended interview form which includes nine questions considering the functions of the HRM was utilized as the data collection tool. Research results showed that teachers know the duties and responsibilities which are declared in their job definition but they do not consider some of the significant professional efficiencies such as planning, assessment and evaluation. Moreover, the ministry does not make long-term plans in order to determine the required human resources, and also the functionality and subjectivity of the system is under discussion in terms of selection and appointment. What's more, the desired aims cannot be reached in terms of professional development. Teachers have the anxiety of performance evaluation based on accountability, and they emphasize fair and subjectivity in terms of payment, rewarding and discipline.

Chorus education, which is being practiced within the framework of music education’s branch of voice training, has significant impacts on an individual’s philosophy of life, self-confidence level and socialization. An individual assesses his own life satisfaction level cognitively in terms of many aspects. Chorus education can be seen as the most prominent and contributing aspect as it helps people feel satisfied and happy and moreover, it makes their life more meaningful in various ways. The study aims to interpret the effect of choral participations of middle school students on their life satisfaction. Accordingly, in this research, ‘satisfaction with life scale’ developed by Diener, Emmons, Laresen and Griffin  - later translated in Turkish by Koker - has been used. To that end, middle school students’ satisfaction with life has been investigated through comparisons done within the context of factors such as; gender, age, grade, previous musical instrument experiences as well as choral participation. As a result of the research, it has been identified that the life satisfaction does not vary significantly according to gender, age, grade or previous musical instrument experiences; yet it has been found that that there is a positive effect of choral participation on students’ life with satisfaction.

This study aims to assess the effects of teaching programming with mBlock on self-efficacy perceptions and attitudes considering programming. Particularly, this study tries to research whether there is a gender difference in middle school students or not. The study was conducted in pre-test/post-test quasi experimental design. The participants of the study which was completed in twelve weeks were 82 middle school students. The data were collected through “Educational Computer Games Assisted Learning Coding Attitude Scale” and “Computer Programming Self-efficacy Scale”. The results of the research indicate that although the self-efficacy perceptions of boys towards programming were higher than the girls’ at the beginning of the research, this difference was closed at the end of the research. The results also show that teaching programming with mBlock to middle school students did not cause gender differences in self-efficacy perceptions and attitudes regarding programming. Although girls’ attitudes regarding programming were slightly higher than boys’, the difference was not considered to be significant. In addition, it was found that programming with mBlock significantly increased students' self-efficacy perceptions and attitudes towards programming. As a result, teaching programming with mBlock can provide similar possibilities for both genders in self-efficacy perceptions and attitudes regarding programming.

The purpose of this study is to reveal factors considered by mathematics student teachers while posing modelling problems. The participants were twenty-seven mathematics student teachers and posed their modelling problems within their groups. The data were obtained from the modelling problems posed by the participants, their solutions on these problems and the groups’ reflective diaries regarding their problem posing and solution processes. The data were analyzed by using content analysis and the codes were constructed according to the problems’ contents. The participants' diaries were examined in terms of generated codes and the expressions supporting/relating the codes were determined. While designing the problems, the participants considered the factors such as being interesting, understandable, appropriateness to real life and modelling process, model construction, and usability of different mathematical concepts. Their solutions were generally handled in terms of usage of the mathematical statements, appropriateness to the modelling process and being meaningful for real life. Modelling training should be provided to enable the student teachers to develop modelling problems and their designs should be examined and the feedbacks should be given.
