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 aim of this study is to review the academic papers written in Turkey on the subject of school readiness, with regard to one of the dimensions of school readiness, that of schools’ readiness for children. The examinations were carried out using one of the qualitative research designs, namely the nested case study design. The study universe consists of 45 articles in Turkish that include the subject of school readiness published in 26 academic journals between the years 2012-2017. With the purposeful sampling method, 14 academic papers that include the dimension of schools’ readiness for children were taken as the study sample. The obtained data were analyzed by descriptive content analysis. The analysis results show that half of the studies reviewed were published in the year 2014. It was observed that in the papers, among the components of the dimension of schools’ readiness for children, the schools’ physical readiness component was most often mentioned. In the articles including the schools’ physical readiness component, it was observed that mainly, findings indicating that schools were not physically suitable for first-year pupils’ level of physical development had been made. As for the component of teachers’ readiness, research findings were accessed relating to the fact that teachers were not prepared for students in terms of their attitudes and values as well as their professional knowledge and skills. Moreover, in the articles, in terms of readiness of the schedule for students, findings were accessed regarding the fact that primary school programmes were not suitable for the levels of the students or for their levels of readiness.

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.

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.

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.

The aim of this research; secondary, high school and university levels of the students to understand the concepts related to ecology of Bayburt in Turkey. In this study, a progressive research method was used. In this method, conceptual understanding test was used as data collection tool. Open-ended test questions were used in this study. The test consisted of 150 students, 50 were from the secondary school, 50 were from the high school and 50 from the university in Bayburt. The data obtained from the test indicate that the meanings of the ecological concept are in different categories and that this concept is not fully understood by the students at all three levels of learning. While students at secondary level relate the concepts related to ecology to their everyday use, high school and university students have more scientific definitions in their descriptions. In addition, misconceptions regarding these concepts have been identified at all levels of learning.

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.

This research aims to complete Turkish adaptation, validity and reliability studies for the Math and Me Survey developed by Adelson and McCoach for use in determining the students’ attitudes towards mathematics in the transition from primary school to middle school. Within the scope of validity and reliability studies for the scale, data gathered from 1169 primary school students had item analysis, exploratory factor analysis and confirmatory factor analysis performed. In line with this, 18 items from the original scale were translated to Turkish and item equivalence between the original English and Turkish translation was ensured. During item analysis to determine the construct validity of the scale, an item with low item total correlation value was removed from the scale. The Cronbach alpha coefficient was calculated as .93. The Cronbach alpha coefficients from the scale subdimensions of Enjoyment and Self-Perception were calculated as .91 and .88. The confirmatory factor analysis results for the scale revealed perfect fit with the construct determined in the exploratory factor analysis results. Thus, the Math and Me survey can be said to be a valid and reliable tool for use in Turkish culture.

The purpose of this study was to investigate the meanings assigned by pre-service teachers to the wastepaper basket and waste (crumpled) papers in their drawings of a scientist. The study was carried out with 220 pre-service teachers during the 2015-2016 academic years. A phenomenological research method was used. First, the pre-service teachers were administered the ‘Draw-A-Scientist Test’ in order to identify their images of a scientist and then they were asked to describe and explain the scientist they drew. And a semi-structured interview was performed with the 34 pre-service teachers who included a wastepaper basket and waste paper in their drawings in order to identify the meanings assigned to the wastepaper and wastepaper basket by these teachers. The data were analysed by using content analysis. The results of the analysis showed that with these figures the pre-service teachers revealed their belief that when scientists conduct research, they follow a confirmatory experimental process in a similar manner to the way school science experiments. Based on these results, it can be suggested in the analysis of the drawings that waste paper and wastepaper baskets can be regarded as indicators of the stereotypical image of scientists and of the scientific method they use.

The inorganic chemistry is one of the essential courses in the education of pre-service chemistry teachers. This study investigates the differences between the adopted learning approaches and achievements of Turkish pre-service chemistry teachers' who received the inorganic chemistry course from the same lecturer. The purposes of this study are to explore the relationship between the inorganic chemistry achievements and the adopted learning approaches of pre-service chemistry teachers and to examine the effect of their learning approaches on their inorganic chemistry achievements. This study was conducted with 127 pre-service chemistry teachers from the Department of Chemistry Education at one of the public university in Turkey. “The Study Process Questionnaire” and “The Inorganic Chemistry Achievement Exams” were used as the data collection tools. The descriptive statistics and chi-square test were used for the data analysis. The results of the study displayed that (1) there is a significant relationship between the pre-service chemistry teachers’ inorganic chemistry achievement and their learning approach; (2) their learning approach has 34 % effect on their inorganic chemistry achievements according to Somers'd value.

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.

It was aimed in this study to determine the teacher candidates' views on the augmented reality applications in education. It is a descriptive study to identify the present situation. Survey model, one of the quantitative research methods, was used in the research. The sample group of the study is comprised of 220 teacher candidates who are studying in the 2nd Grade of 8 departments in Mersin University Faculty of Education. Consisting of 4 sections, 22 items and an open-ended question, a questionnaire was used as a data collection tool in the study to determine the views of teacher candidates about the augmented reality applications in education. The findings obtained from the analysis of the data were shown in frequency and percentage. Qualitative findings obtained from the open-ended question were classified into codes and themes through content analysis method, and frequency and percentages of codes were given. It was found in the study that the teacher candidates did not know well enough about the augmented reality applications and that those who knew them found these applications very entertaining, motivating and facilitating learning, and were also of the same mind to use them widely in education.

Gender differences in mathematics learning outcomes are still evident in many countries participating in large scale international testing, as well as in national testing in Israel, the context in which the study reported here was conducted. The participants were 281 students from three Israeli elementary schools and were in grades 4 and 6. The students completed a questionnaire with items based on a selection of variables included in explanatory models for gender differences in mathematics. It was found that many students held gendered beliefs related to mathematics learning, particularly when the questions asked related to themselves or to significant others in their lives (parents and teachers); the views of the majority of students were gender neutral. When presented with two photographs -a man, and a woman- and asked who was the one more likely to work with mathematics, it was clear that the students’ choices and explanations echoed perceptions of mathematics as a male domain.

The purpose of this study is to determine the attitude towards Turkish Course and reveal the perception of students towards Turkish Course and teacher. In this context, a personal information form and Attitude Towards Turkish Course (ATTC) Scale were applied to 419 students who receive education in the center of Kirsehir province, in Turkey. In addition to that, the metaphors of students towards Turkish teacher and course were compiled by means of semi-structured interview form. The students were also required to draw pictures that express their feelings towards Turkish Course. The results can be summarized as follows: it was seen that Turkish teachers were likened to an “angel”, “cotton” and “panda”, and happy emojis and heart figures were drawn towards Turkish Course. It was understood that the attitudes of- female students in comparison to male students, the ones who possess a phone to the ones who do not, the ones who have a higher literacy level to the ones with lower literacy level, the ones with more social media followers to the ones with less followers and the ones who spend more extracurricular time with to the ones who do not- have been developed more positively.

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.
