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.

Fatma Cobanoglu , Gulsum Sertel , Sevda Seven Sarkaya


...

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.

...

To determine the effectiveness of a peer tutorial strategy in the school achievement of English to high school students, whose mother tongue is not English, we made a comparison of two groups; in one, peer tutoring was carried out through the support of high average students and compared with the results of a group that did not receive the intervention. The tutors were 121 students who scored higher than 80 points in the initial exam and accepted to participate in the program. The group of tutees was formed by those who obtained scores lower than 65 and accepted to be tutored (101 formed the experimental group and 112 the control group). The peer tutoring was done in the classroom with the monitoring of the teacher, lasted 11 weeks, and focused on taking class notes and comparing them, giving feedback and clarifying doubts for 30 minutes after the teacher's explanation. The results of the midterm exam and final exam were analyzed through the Student's t-test, showing significant differences in the group that was tutored compared to the low-performing students who did not receive the intervention. The procedure was effective, finding that the use of peer support can improve school performance. It is necessary to monitor the profile of the tutors and systematize the tutorial strategy.

This paper aims to test the reliability and validity of the Turkish adaptation of DeBaryshe and Binder's Parent Reading Belief Inventory (PRBI) and to investigate parents' literacy beliefs. The primary focus of this paper is to explore parents’ beliefs and practices and their relatedness on the emergent literacy of their children aged 3–7 (M=69.8 months; SD= 9.33 months). As data collection tools, we availed ourselves of the Parent Reading Belief Inventory,(PRBI), Home Literacy Inventory (HLI) and Child Literacy Behaviours (CLB). In addition, the Personal Information Form, prepared by the researchers, was utilized. Moreover, confirmatory factor analyses were performed on samples of parents from Adana, a city in southern Turkey (N= 952). The study showed that a seven-factor structure in the original form of the PRBI was validated , excluding items 8, 30 and 31. Consistent with the results of the confirmatory factor analysis and reliability analysis, it can be concluded that the PRBI is a valid and reliable tool to investigate the process of parents' literacy activities with their children in Turkey.

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.

Technology is an indispensable part of the educational curriculum, and large budgets have been allocated to provide technological infrastructure in secondary education institutions in Turkey. It is important that teachers have the technological pedagogical content knowledge (TPCK) to successfully integrate technology into their courses. The aim of this study is to examine the development of the TPCK of a mathematics teacher who participated in in-service training course organized for the use of Geogebra software in geometry teaching. The in-service training is designed in accordance with the Technology Integration Model stages, and Geogebra software is used taking into account the learning outcomes of 9th and 10th grade secondary school geometry. The case study method has been employed, and data was collected through interviews, observation, self-assessment forms, and field notes. The findings show that the in-service training helped the maths teacher integrate technology in the teaching and developed the knowledge of curriculum, students’ understandings and learnings, and instructional strategies and methods. With regard to research recommendations and results, professional development programs that will provide TPCK development can be organized so that teachers can use the ever-evolving technologies in their classes along with the appropriate pedagogical approaches.

Students’ test anxiety is known to have significant influences on essential academic outcomes, and given the increased testing of school-aged children gender differences also appear in dimensions of test anxiety: thoughts, off-task behaviors, and autonomic reactions. This study examined: (i) whether there is a pattern of correlations exist among three dimensions of test anxiety that are tapped by the Children’s Test Anxiety Scale (Wren & Benson, 2004) and (ii) whether gender differences exist in the strength of these test anxiety dimensions. Students (N= 414) from 3 public schools, attending to the fourth grade (205 Females; 209 Males) were asked to rate on the thoughts (cognitive), off-task behaviors (behavioral), autonomic reactions (physiological) dimensions. The results revealed a strong relationship between thoughts and autonomic reactions (r = .57). Applying a multivariate approach, gender differences were found to be significant in overall test anxiety favoring females. Results also revealed a small female advantage for thoughts and autonomic reactions, Ƞ2 = .012 and Ƞ2= .016; but quite a small male advantage for off-task behaviors Ƞ2=.009. Taken as a whole, we need to seriously consider the implications of these differences and pay attention particularly to females in elementary schools.

This is a descriptive study investigating the perception of children about discipline through metaphors developed by them. A total of 445 students participated in the research and the data was collected with the “Discipline Metaphors Survey (DMS)” developed by the researchers. At the end of the study, 143 metaphors, 94 positive and 49 negative, about discipline were gathered. The participating children mostly perceived discipline as a phenomenon guiding their behavior, maintaining the order, and as being necessary for the social life. Learning and development, self-control, protection mechanism, planned and ordered study, as well as collaboration are further positive perceptions of discipline. Negative metaphors, on the other hand, were usually power and control oriented and the discipline committee was described as the ultimate authority entity. Based on the students’ views, discipline was provided through classroom rules and for misbehavior the teachers tended to use warnings, shouting/scolding and punishment. School rules, dress code as well as prohibited product checks at the entrance of the school, the Discipline Committee and discipline rules were reported as the most common practices of discipline in school. Most of the students who thought that punishment is necessary for discipline stated that the punishment should not involve physical violence and that it should be reasonable. Further expectations of the students found in the study included warning without shouting, doing enjoyable activities to address individual differences, informing everybody about the rules. Children’s perception about discipline was usually affected by their teachers followed by their family and the school administration respectively.

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.
