The purpose of this study is to develop a reliable and valid measurement tool which will reveal teachers’ self-competences in education process. Participants of the study are 300 teachers working at state primary schools in the province of Gaziantep, Results of the exploratory factor analysis administered to the scale in order to determine its construct validity, indicated that it has four sub-dimensions. In accordance with the results of confirmatory factor analysis RMSEA was measured .050 level fit index. The determined levels for GFI is found to be 0.88, whereas for AGFI, 0.85 for NFI, 0.94 for CFI 0.98 and 0.94 for RFI. Also, non normed fit index, (NNFI) has been observed as 0.97. Four dimensions of the scale which was composed of 23 items account for approximately 54% of the total variance. Cronbach's alpha coefficient of internal consistency was counted .86 for the first dimension; .82 for the second dimension, .67 for the third dimension, .70 for the fourth dimension, and .92 for the entire scale. The scale, developed in order to measure teachers’ self-efficacy in the teaching process, proved to be valid and reliable based on the results of the related analyses.

Facilitating effective mathematics learning and higher mathematics achievement have long been recognized as a key to the scientific and technological advancement of the African continent. While the central role that language proficiency plays in mathematics teaching and learning has received an overwhelming research attention in the literature over the past two decades, this is not the case among African policy-makers and political leaders. Drawing mainly from our professional experiences as mathematics educators and from the international research literature, our primary intent in this paper is to answer this question: How does the learning of mathematics in English at the basic school level help or hinder students’ mathematical proficiency? To answer this question, the paper is organized as follows. The first part, the introduction, gives a brief overview of the language of learning and teaching in Africa. The second part describes the method and conceptual framework undergirding the research. In the third section, we have analyzed the effects of mathematics learning and teaching through English for basic students whose mother tongue is a Ghanaian language. The conclusion offers four recommendations for developing and improving the mathematics proficiency of students in basic schools.

Grolnick and Ryan assume that an autonomy supportive environment leads to higher learner engagement and thus to greater achievements and deeper understanding of content. In school, knowledge acquisition (rote learning as well as conceptual learning) are regarded as most important. In this study, we examined the effects of teachers’ autonomy supportive vs. controlling behavior on knowledge acquisition as measured by reproduction as well as at higher cognitive levels. The sample consisted of seventh graders (N=85; M=12.85 years; SD=1.6 years). One week in advance to the teaching unit, the students were tested for prior knowledge using two knowledge tests. Test 1 used multiple-choice items to address rote learning and Test 2 used an open response format to address conceptual learning. One week after the teaching unit, the same knowledge tests were used to assess the learning outcome. Analysis of the knowledge tests suggests that the students taught in an autonomy supportive environment develop greater conceptual knowledge than those taught in a controlling environment. Rote learning was not affected.

This study investigated the effects of analogy on the elimination of students’ misconceptions about direct current circuits, students’ achievement and the attitudes towards physics lessons. The sample of this study consisted of 51 11th grade students from two different classes. While one of the classes was the experimental group where analogy was used in the lessons, the other class was the control group where the traditional methods are employed in lessons and this selection was made randomly. When the obtained results were examined, it was seen that teaching with analogy has a significantly positive effect on the elimination of misconception and achievement although it has almost no effect on the attitudes of towards physics.

The purpose of this study was to investigate how mental rotation strategies affect the identification of chemical structural formulas. This study conducted event-related potentials (ERPs) experiments. In addition to the data collected in the ERPs, a Chemical Structure Conceptual Questionnaire and interviews were also administered for data collection. Eighteen university students majoring in chemistry were recruited. In the ERP experiments, the participants were required to identify 2D figures, 2D chemical structural formulas, 3D objects and 3D chemical structural formulas. The contours of 2D figures are similar to those of 2D chemical structural formulas, but they contain no content knowledge. Likewise, the contours of 3D objects are similar to 3D chemical structural formulas without content knowledge. The results showed that all students used similar strategies of mental rotation in identifying 2D figures, 3D objects and 3D chemical structural formulas. However, the high-achieving students used different strategies in identifying 2D figures and chemical structural formulas, while the low-achieving students tended to use similar strategies of mental rotation in identifying both 2D figures and chemical structural formulas. The results indicate that some of the difficulties in identifying 2D chemical structural formulas that students encounter are due to their inappropriate strategies of mental rotation.

Technological Pedagogical Content Knowledge (TPACK) is a model that explains how teachers use technology more effectively in the context of technological, pedagogical, and content knowledge. Teachers' TPACK competencies play great importance in this regard. Lesson study has also been playing significant roles in the development of teachers' professional trainings. When the researches on TPACK and lesson study have been analyzed, the research is expected to provide significant contributions to the literature. This study aims to present reflections from a lesson study practice that carried out to urge techno-pedagogical competencies of the secondary school mathematics teachers and to reveal the development of teachers’ progress. The study used case study method, and it was conducted with three in-service teachers. The research data were collected through semi-structured interviews, voice recorder, and observation notes. To analyze the collected data, descriptive analysis method was used. The results have revealed that teachers have made much more progress in designing, implementing, and problem solving in terms of TPACK competencies. It has also been determined that teachers’ development of openness to the innovations was limited. This limitation appeared to emerge as a result of teachers’ time anxiety and insufficient knowledge regarding the use of technology.

In order to reflect the integration of the teachers’ content knowledge, pedagogical knowledge, and technology usage skills to the class context and to provide the expected outputs for the program's purposes, it is needed to be revealed the different dimensions of Technological Pedagogical Content Knowledge (TPACK). In this study, it was aimed to investigate the teacher training programmes related to pre-service science teachers’ TPACK. This study was designed as a cross-sectional study. In the 2015-2016 academic year, a total of 269 pre-service teachers (73 of them from 1st grade, 73 of them from 2nd grade, 87 of them from 3rd and 36 of them from 4th grade students) attending Science Education Department participated in this study. As a data collection tool, 7 subscales of “Technological Pedagogical Content Knowledge Scale of Pre-Service Teachers”; namely, technology knowledge, pedagogical knowledge, content knowledge, technological pedagogical knowledge, technological content knowledge, pedagogical content knowledge, and technological pedagogical content knowledge were used. According to the results, as the class level of pre-service teacher increases, their level of technological pedagogical content knowledge increases as well. Moreover, there is a significant difference on behalf of pre-service teachers at the 1st grade in all dimensions of technological pedagogical content knowledge scale.

Effective school administrators and teachers are those who provide the least restrictive learning environments for all students. The main goal of this study was to analyze the effects of inclusive science education on the general education population of middle school students’ scientific conceptual understandings. The study was designed as a quasi-experimental model and conducted in a middle school in a large urban school district in Midwestern US. Approximately 4% of students in the school were receiving special education services. The participants in the study were selected through non-random selection. The participants of this study included 20 students without disabilities in each classroom with a total number of 120 students from a total of six different middle school classrooms. The study included two classrooms (one inclusive and one non-inclusive) for each grade level (6, 7, and 8). The conceptual change of students without disabilities was measured using the Density Assessment, which included 20 multiple choice questions. SPSS program was used for data analyses. Paired samples t-test and a multivariate group analysis test were conducted to investigate significant differences on students’ conceptual understandings. The findings showed that the effect of inclusive education was significant and positive on the conceptual understanding of students without disabilities in inclusive science classrooms.

The purpose of this study was to investigate the effects of learning activities based on argumentation about “Force and Motion” unit on conceptual understanding and views about establishing thinking friendly classroom environment of 7th graders. The study was conducted with total 39 students (20 students in experimental group and 19 students in control group) in a secondary school. The experimental group received learning activities based on argumentation while the control group received regular science learning depending on the current science curriculum for over five week period. Both groups were given Force and Motion Concept Test and Thinking Friendly Classroom Scale before and after the instruction. Besides, six students from the experimental group were interviewed after the instruction about conceptual understanding and thinking friendly classroom features by a form developed by the researchers. The results showed that there isn’t a significant difference between conceptual understandings of experimental and control group students. Besides, it was found that there is a significant difference between thinking friendly classroom scale of experimental and control group students in favor of experimental group. Moreover, the results of the interviews conducted with six of experimental group indicated that they feel themselves in thinking friendly classrooms and with a fine conceptual understandings are fine although they have some misconceptions.

Mathematics educators have reported on many issues regarding students’ mathematical education, particularly students who received mathematics education at different departments such as engineering, science or primary school, including their difficulties with mathematical concepts, their understanding of and preferences for mathematical concepts. This study aimed to investigate the opinions of primary-school teacher education students in terms of their perceptions of difficulty level of the mathematics courses, change in their achievement, if there is any, and interest in mathematics after completing these courses, and factors affecting their achievement and interest level in these courses. Being qualitative in nature, this study was a case study. The data were analyzed using the content analysis and descriptive methods. According to the results, most students stated that they faced mathematics course content with unexpected level of difficulty. After taking basic mathematics courses, the percentage of students with decreased level of interest and achievement in mathematics was found higher than the students who experienced an increase in their interest and achievement. Students underlined such significant factors for the change of their interest and achievement in mathematics as prior knowledge, lecturer(s), and content coverage. Finally, most of the students viewed mathematics courses as a beneficiary tool for their professional development.

This research aimed to investigate relationships between quality of work life, burnout, school alienation, affective commitment and organizational citizenship behaviors. In this context, a model was proposed based on the literature review and the model was tested through structural equation model. The study group of the research consists of 314 volunteer teachers working in the state schools in Kilis in 2016-2017 academic years. The data was collected through work-related quality of life scale, burnout scale, school alienation scale, affective commitment scale and organizational citizenship behaviors scale. The analysis with descriptive, correlation, path and bootstrap methods were used to analyze the data. As a result of the analysis, it was found that teachers' perceptions for quality of work life have a negative effect on burnout and school alienation, whereas they have a positive effect on affective commitment. Besides, their perceptions for affective commitment have a positive impact on organizational citizenship behaviors. Another important result derived from the research is that teachers' perceptions for burnout and school alienation play partial mediation roles in the effect of their perceptions for quality of work life on affective commitment. Based on these results, it can be suggested that teachers' working conditions should be constantly improved.

Higher education institutions increasingly seek to promote students’ intercultural competence (IC), yet its conceptualization remains a challenge. The first aim of this study was to explore how a purposive sample of n=77 domestic, undergraduate students at a public university in Germany define IC. The second aim was to assess to what extent such definitions are context-dependent by comparing IC definitions provided by domestic students (with predominantly German nationality and little international experience/exposure) with those provided by n=130 international, undergraduate students at a private university in Germany (with predominantly non-German nationality and more extensive international experience/exposure). A qualitative content analysis showed that domestic students defined IC mostly in terms of attitudes followed by external outcomes while the opposite was true for the international students. Differences in IC definitions between the two samples are discussed with regard to various contextual factors. Our results suggest that such contextual factors should be considered when designing measures to promote IC development in university students.

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 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 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.

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.

The purpose of this work is to adapt the existing Moral Competency Index (MCI) developed by Lennick and Kiel in a sample of teachers. The validated Turkish version of MCI is based on the item pool of the original MCI with a slight adaptation of the items to fit the context of teacher leadership. The translated form was administered to 773 teachers in Gaziantep city. Exploratory factor analysis, Cronbach’s Alpha and Split-half reliability, and item analysis were performed through SPSS, while the first and second order confirmatory factor analyses were performed through AMOS. Results showed that adapted Turkish form of MCI (Ogretmen Ahlaki Yeterlik Olcegi) is reliable and valid, and the four-dimensional original factorial structure (integrity, responsibility, forgiveness, and compassion) was confirmed and maintained. Finally, multiple regression analyses were performed. Results showed that female teachers have higher levels of moral competencies in the dimensions of integrity and forgiveness. Also, as teachers’ age increases, their general moral competency scores increase in the dimensions of integrity, responsibility, and compassion.

The purpose of this study was to assess the correlation and predictive relationship between self-determination and quality of life of college students with disabilities. Subjects were 145 senior college students recruited from northern Taiwan. Subjects' age ranged from 22 to 25 years and their disabilities varied, including visual impairments (n = 16), hearing impairments (n = 17), speech/language impairment (n = 6), physical disabilities (n = 40), specific learning disability (n = 26), emotional and behavior disorders (n = 5), multiple disabilities (n = 4), autism (n = 23), and health impairments (n = 8). Two measures, the Self-Determination Scale for College Students (SDSCS) and WHOQOL-BREF were used to collect data. The subjects completed the SDSCS in their senior year of college, whereas the WHOQOL-BREF data were collected one year after their graduation. The Pearson correlation and stepwise multiple regression analyses were used to assess the correlation between the SDSCS and the WHOQOL-BREF. Results showed that positive correlations were found between self-determination and quality of life. Subjects’ scores on the SDSCS subscales (Self-Realization, Psychological Empowerment, Autonomy) were able to explain between 30.3%-53.2% of the total variance of their scores on the WHOQOL-BREF domains (Psychological, Social Relationships, Environment). The results of this study re-confirmed the positive correlation between self-determination and quality of life of individuals with disabilities. Furthermore, the study highlighted that self-determination not only has an immediate impact on quality of life for people with disabilities, but it seems to have a long-lasting effect. Suggestions and implications are provided.

Recent science education standards emphasize the importance of the instruction of nature of science (NOS) concepts at all levels of schooling from pre-K to K-12. Delivering a proper NOS education to students is excessively dependent on their teachers with an adequate understanding of NOS concepts. The present study investigated the science conceptions of preschool and elementary teacher candidates. The data collected from a total of 506 prospective teachers were analyzed with respect to the following demographic variables: majors, genders, grade levels, high schools and GPAs of teacher candidates. “Student Understanding of Science and Scientific Inquiry (SUSSI)” developed originally by Liang et al. (2008) was the instrument used to collect data in this study. The data analyses were conducted using MANOVA and Pearson Correlation Coefficient. The corresponding mean scores of the teacher candidates in specific aspects of NOS ranged from “poor” to “informed” conceptions of science. All but one of the demographic variables yielded statistically insignificant results on the NOS conceptions of teacher candidates. The majors of the teacher candidates were detected as a significant variable influencing the conceptions of the teacher candidates. The results of the study were discussed in reference with the relevant literature.

The purpose of this research is to evaluate the effectiveness of the activities, which are prepared by teaching techniques that support scientific creativity, on the scientific creativity levels of prospective pre-school teachers. In the research, combined design is used, which is one of the mixed research approaches. The study group of the research included a total of 46 prospective pre-school teachers who have studied in the Education Faculty of Kafkas University in 2016-2017 academic year. The applications were carried out in the "science education" which is one of the third-grade 5th-semester courses of the pre-primary education program. The application process was completed in 4 hours a week for a total of 40 hours. In the analysis of the quantitative data collected by Scientific Creativity Test, percentage calculation and t-test were used. Explanatory and inferential codes were used in the analysis of qualitative data obtained from the in-class observations. As a result of the research, it was seen that the course activities in which different techniques were used positively influenced the scientific creativity levels of the prospective teachers. Prospective teachers' level of skills involved in creative trait, creative process, and creative product sub-dimensions also developed. It has been suggested in the direction of these results that different techniques should be used together to develop scientific creativity.
