Examination of the Relationship Between TPACK Competencies and Mathematics Teaching Anxiety: The Mediating Role of Mathematics Anxiety

This study aimed at exploring the mediating role of mathematics anxiety in the relationship between TPACK competencies and mathematics teaching anxiety. This mediation role stated in the hypothesis of the study was tested through structural equation modeling using data from 426 pre-service mathematics teachers selected through criterion sampling. TPACK Competencies Scale, Mathematics Anxiety Scale, and Mathematics Teaching Anxiety Scale were used to collect data. The data were analyzed using descriptive statistics, correlation analysis, and path analysis. The study revealed a negative relationship between TPACK competencies and mathematics anxiety, and mathematics teaching anxiety, while there was a positive relationship between mathematics anxiety and mathematics teaching anxiety. The results suggested that pre-service teachers' mathematics anxiety had a mediating role in accounting for the relationship between TPACK competencies and mathematics teaching anxiety. In addition, TPACK competencies explained 68% of the total variance in mathematics teaching anxiety through mathematics anxiety in the structural equation model. The findings are discussed in light of the related literature, and implications are offered for practitioners and researchers.   

APEC ülkelerinde yenilenebilir enerji kaynaklarının hava kirliliğinin refah maliyetlerini azaltıcI rolü

The main purpose of this study is to determine the possible long run impacts of renewable energy supply on the welfare cost of premature deaths caused by air pollution in the Asia-Pacific Economic Cooperation (APEC) countries during 1990-2016 by using dynamic panel data techniques. The long run elasticity results showed that the increasing supply of renewable energy sources reduces the welfare cost of air pollution. Empirical findings revealed that clean energy should not just seen as a sustainable energy source but also considered as an efficient way to struggle with possible negative externalities of pollution.Bu çalışmanın ana amacı 1990-2016 yılları süresince Asya-Pasifik Ekonomik İşbirliği (APEC) ülkelerinde yenilenebilir enerji arzının hava kirliliği kaynaklı erken ölümlerin refah maliyetleri üzerindeki uzun dönemli etkilerini dinamik panel veri teknikleri kullanarak incelemektir. Uzun dönem esneklik sonuçları yenilenebilir enerji kaynakları arzındaki artışların hava kirliliğinin refah maliyetlerini azalttığını ortaya koymuştur. Uygulama sonuçları, yenilenebilir enerjinin sadece sürdürülebilir bir enerji kaynağı olarak görülmemesi, aynı zamanda kirliliğin muhtemel dışsallıkları ile baş etmenin etkin bir yolu olarak da değerlendirilmesi gerektiğini ortaya çıkarmıştır

Higher education, and the future of distance teaching and perceptions of academics; An investigation in Turkey

Purpose - The purpose of this study is to analyze distance education and explore the implications for tourism education from the perspective of academics in the higher education system. Design - This study was designed as exploratory research in order to measure its effects on the university academics. Methodology - A questionnaire-based survey was used to collect data. A total of 408 questionnaires from participants were found to be a satisfactory sample. Simple random sampling technique was used by selecting a sample of academics who were teaching distance education in universities in Turkey, of which 228 were from tourism and the rest were from other social science departments. Findings - The system entails an excessive workload for faculty to provide satisfactory preparation, while some technical problems such as interruptions and disconnections occurred frequently. It was also found that the system is less interactive, does not provide control over students’ examination, and it is difficult to keep students interested in active participation. This system was found to be less effective and impractical than traditional on-site instruction in subject areas, especially where hands-on practice is required. Originality of the research - This study reveals the views of instructors during and immediately after the Covid 19 pandemic, and it is also one of the first studies to examine instructors’ opinions on distance education, including suggestions for professionals as their scholarly and applicable contributions

Evaluation of the effect of psychological empowerment on employee performance in the health sector in the COVID-19 pandemic

Bu araştırmanın amacı, Türkiye'de COVID-19 pandemisi sürecinde sağlık çalışanlarında psikolojik güçlendirme ile işgören performansı arasındaki ilişkiyi incelemektir. Çalışma, kesitsel tipte tanımlayıcı bir araştırmadır. Araştırma verileri katılımcıları tanıtıcı bilgi formu, Psikolojik Güçlendirme Ölçeği ve İşgören Performansı Ölçeğinden oluşan anket formu ile toplanmıştır. Veriler, Google Forms’ta oluşturulan online anket formu aracılığıyla, 580 sağlık çalışanından elde edilmiştir. Çalışmada psikolojik güçlendirme ve alt boyutlarından etki, anlamlılık ve yeterlilik boyutlarının işgören performansı üzerinde pozitif etkisi olduğu bulunmuş, ancak özerklik alt boyutunun istatistiksel olarak anlamlı bir etkisi bulunmamıştır. İşgören performansı üzerinde en fazla etkisi olan boyutun yeterlilik alt boyutu olduğu görülmüştür. Ayrıca katılımcıların psikolojik güçlendirme ve işgören performansına ilişkin ortalama puanlarının cinsiyet, yaş, meslek ve çalışma süresine göre istatistiksel olarak anlamlı farklılıklar gösterdiği tespit edilmiştir. Araştırmada sağlık çalışanlarının psikolojik olarak güçlendirilmesinin performanslarını olumlu olarak etkileyeceği sonucuna ulaşılmıştır. Sağlık çalışanlarının yeterliliğinin, etkilerinin ve mesleklerine yükledikleri anlamların geliştirilmesinin, performanslarının artırmasına büyük katkı sağlayabileceği düşünülmektedir.The aim of this study is to examine the relationship between psychological empowerment and employee performance in healthcare workers during the COVID 19 pandemic in Turkey. The study is a crosssectional descriptive study. The research data were collected with a questionnaire consisting of the participants' introductory information form, the Psychological Empowerment Scale and the Employee Performance Scale. The data were obtained from 580 healthcare workers through the online questionnaire created in Google Forms. In the study, it was found that the psychological empowerment and its subdimensions of impact, significance and competence had a positive effect on employee performance, but the autonomy sub-dimension did not have a statistically significant effect. It has been seen that the dimension with the most impact on employee performance is the sub-dimension of competence. In addition, it was determined that the average scores of the participants regarding psychological empowerment and employee performance showed statistically significant differences according to gender, age, occupation and working time. In the study, it was concluded that the psychological empowerment of health workers would positively affect their performance. It is thought that improving the competence of health workers, their effects and the meanings they attribute to their professions may contribute to increasing their performance
