Preservice Science Teachers’ Efficacy Regarding a Socioscientific Issue: A Belief System Approach

The aim of the present study was to understand the nature of teaching efficacy beliefs related to a socioscientific issue (SSI). We investigated Turkish preservice science teachers’ teaching efficacy beliefs about genetically modified (GM) foods using a belief system approach. We assumed that preservice teachers’ beliefs about GM foods (content knowledge, risk perceptions, moral beliefs, and religious beliefs) and their teaching efficacy beliefs about this topic constitute a belief system, and these beliefs are interrelated due to core educational beliefs. We used an exploratory mixed design to test this model. We developed and administered specific questionnaires to probe the belief system model. The sample for the quantitative part of this study included 441 preservice science teachers from eight universities. We randomly selected eight participants in this group for follow-up interviews. The results showed that preservice science teachers held moderately high teaching efficacy beliefs. Learning and teaching experiences, communication skills, vicarious experiences, emotional states, and interest in the topic were sources of this efficacy. In addition, content knowledge and risk perceptions were predictors of teaching efficacy. We believe that epistemologies based on traditional teaching and the values attached to science teaching are the core beliefs that affect the relationship between predictor variables and teaching efficacy.     

Analogical reasoning for understanding solution rates: students’ conceptual change and chemical explanations

The study aims to demonstrate evidence of (a) students’ conceptual change on solution rates; (b) students’ sub‐microscopic explanations of dissolution; and (c) retention of the concepts of solution rates. The sample consists of 44 Grade 9 students (18 boys and 26 girls) drawn purposively from two different classes (22 each) in the city of Trabzon, Turkey. The current study incorporates multiple methods of data collection: items from a solution concept test, clinical interviews and examination of students’ self‐assessment tasks. The results reveal that there is a statistically significant difference between scores in pre‐test and post‐test and between pre‐test and delayed test (p < 0.05). This research indicates that the intervention has improved students’ understanding of the conceptual relationship between solution rates and the sub‐microscopic explanation of dissolution. It has also helped in overcoming students’ alternative conceptions to some extent. However, alternative conceptions have not been eliminated completely. In the light of the results, this current study suggests that a simple model such as the four‐step constructivist teaching (4E) is efficient.     

Students and school characteristics related to elementary school students' views of the nature of science

The purpose of this study is to investigate student- and school-level factors that help to explain the difference in the nature of science (NOS) views. Overall, the design of this study is correlational. The sample consisted of 3062 students enrolled in the sixth, seventh, and eighth grades of elementary schools in Turkey. A hierarchical linear modelling was selected as a modelling technique. This study has established the importance of the student's socioeconomic background, learning approaches undertaken, self-efficacy, and motivational goals in the formation of their NOS views. The findings reveal that quality of both the physical infrastructure of schools and the educational resources in schools, parent educational levels, student achievement, self-efficacy, experience of meaningful learning, and learning goal orientation are positively related to different dimensions of student NOS views. Additionally, performance goal orientation and rote learning approaches have a negative relationship with different dimensions of student NOS views.     

Status of Individuals' Planning to Prepare for Retirement in Turkey

This research was conducted in Ankara province for the purpose of examining the status of planning in preparation for retirement as an individual and as a family of individuals who show differences in educational level. Individuals who lived in Ankara province, who were 3 years from retirement according to age limit, and who had social security from one of the three official government plans (The Pensions Fund For Civil Servants of The Republic of Turkey, Social Insurance Institution, or Social Security Organization of Artisans, and Craftsmen and other Self-Employed People) were the research population from which 393 individuals were chosen using the Stratified Random Sampling Method. There was a higher percentage of individuals who stated that they had not planned for retirement than those who had. Of the individuals who stated that they had made plans, 80.7% had made those plans about their financial status. Individuals who thought that it was necessary to have an educational program for preparing for retirement also wanted “financial status” topics at the head of the list of topics for such a program.     

The relationship between reading comprehension strategies and reading attitudes

The aim of this study is to determine the relationship between levels of reading comprehension strategy use, reading attitudes, and the amount of reading per year among elementary school students. The study was conducted with 1316 students (649 girls and 667 boys) attending the fourth and fifth grades of 15 elementary schools in Denizli, Turkey. Stratified Sampling Method was employed to obtain data using Reading Attitude Scale (RAS) and Reading Comprehension Strategies Scale (RCSS). The analyses indicate that reading attitude is a significant predictor of the level of reading comprehension strategies used by students (R² = 0.44). The findings show that there is a negative and low-level relationship (r = ?0.054) between daily time spent reading and the level of strategy used, and a positive and low-level relationship (r = 0.01) between the level of strategy used and the number of books that a child reads per year.     

Quality Teaching and Learning in Australian and South African Universities: Comparing policies and practices

Over the last decade universities across the world have been grappling with quality and quality assurance issues. In several countries national policies on higher education quality assurance have been evolving, mostly with the purpose of putting external systems of quality assurance in place. In many instances, these policies and systems had less effect on the quality of teaching and learning than had been expected. This paper serves as a comparison of national quality policy developments in two countries, Australia and South Africa, and goes on to investigate the emerging tensions in quality policy processes in these countries. Whereas a number of similarities were discerned, differences were as evident, verifying the underlying assumption of the authors that notions of quality, and quality policies and their implementation are very much dependent on the particular localised contexts in which they exist.     

Developing mental orthographic representations in refugee spellers with low literacy: how much input is too much?

Background

We used two principles of implicit learning, variability and complexity, to train mental orthographic representations in refugee English learners to improve spelling.

Methods

Twenty‐eight refugees enrolled in a 10‐week English class were trained on classroom words using stimuli designed to encourage implicit learning. We contrasted high‐variability visual input combined with either high‐linguistic or low‐linguistic complexity, using a short (<5 minute) PowerPoint‐based training. Participants were regularly tested on their spelling and were compared with themselves using single subject design. Individual effect sizes were aggregated across participants, and we used dependent measures t‐tests to compare conditions.

Results

Participants learned significantly more treated words than control words in the high‐variability/low‐complexity condition, but not in the high‐variability/high‐complexity condition.

Conclusions

Refugees can benefit from interventions designed to promote implicit learning but can be overwhelmed by too much input.     

Women’s Sport as a Symbol of Modernity: A Case Study in Turkey

Abstract

Turkey has a distinctive position with regard to its geography and history among Muslim countries. Particular features are its secular system and far reaching modernization processes particularly with respect to the ‘emancipation’ of women. The aim of this paper is to describe and analyze sport and body politics as part of the modernization processes in Turkey and to explore in particular the multiple roles of different groups of women in the reforms initiated by the Turkish Governments. A focus will be on the intersecting influences of gender and social class. The famous archaeologist Halet Çambel will be used as an example of the ‘modern’ woman who embodied reformist ideologies. Çambel was the daughter of an elite family; she was born in Berlin where her father was an attaché at the Turkey embassy. She studied in France and participated in the Olympic Games in 1936. She and another Turkish fencer were the first women from a Muslim country to participate in the Olympic Games. Later she became the most famous archaeologist in Turkey and she stayed physically active all her life. In particular, horse riding became a favourite activity as she travelled to archaeological sites on horseback.     

Fatigue detection in strength training using three-dimensional accelerometry and principal component analysis

Detection of neuro-muscular fatigue in strength training is difficult, due to missing criterion measures and the complexity of fatigue. Thus, a variety of methods are used to determine fatigue. The aim of this study was to use a principal component analysis (PCA) on a multifactorial data-set based on kinematic measurements to determine fatigue. Twenty participants (strength training experienced, 60% male) executed 3 sets of 3 exercises with 50 (12 repetitions), 75 (12 repetitions) and 100%-12 RM (RM). Data were collected with a 3D accelerometer and analysed by a newly developed algorithm to evaluate parameters for each repetition. A PCA with six variables was carried out on the results. A fatigue factor was computed based on the loadings on the first component. One-way ANOVA with Bonferroni post hoc analysis was calculated to test for differences between the intensity levels. All six input variables had high loadings on the first component. The ANOVA showed a significant difference between intensities (p < 0.001). Post-hoc analysis revealed a difference between 100% and the lower intensities (p < 0.05) and no difference between 50 and 75%-12RM. Based on these results, it is possible to distinguish between fatigued and non-fatigued sets of strength training.     

Self and teacher assessment as predictors of proficiency levels of Turkish EFL learners

Although self-assessment of foreign language skills is not a new topic, it has not yet been widely explored in the Turkish English as a Foreign Language (EFL) context. The current study investigates the potential of self-assessment of foreign language skills in determining proficiency levels of Turkish learners of EFL: 239 learners participated in the study. Their receptive language skills were tested with an objective placement test, and the results were compared with the grades assigned by their instructors and the results of criterion-referenced self-assessment scores. Multiple regression analysis revealed that teacher and self-assessment scores were significantly correlated with each other; however, teacher assessment, compared to self-assessment, appeared to be a much stronger predictor of the actual proficiency levels of the participants. In addition to this, participants at lower level of proficiency revealed a common tendency of overestimating their language skills, while with the higher level learners there were clear signs of underestimation.
