A multi-feedback system integrated simulation-based teacher training to scaffold pre-service teachers’ teaching skills: A phenomenological approach
No full textBefore taking full responsibility for a real classroom, pre-service teachers (PTs) can safely experience a rich learning atmosphere in a simulated virtual classroom environment and receive feedback on their lesson planning and teaching performance. This research aims to support and examine the process of structuring PTs’ teaching skills with a multi-source feedback system integrated with simulation-based teacher training (SimInTeach-FBS). A phenomenological approach was employed in order to understand the nature of PT’s experiences from a feedback system focusing on teaching skills. Seventy PTs, twelve mentor teachers (MTs), and six teacher educators (TEs) participated in the study. Various data collection tools were used to gain a deeper understanding of the participants' experiences: reflective journals, open-ended feedback forms, and observation notes. The results of the content analysis showed that teaching experience with SimInTeach-FBS raises self-awareness and improves PTs’ teaching skills. It was revealed that teaching skills were mutually structured, feedback given to the PTs multiplied the effect of the development process, and teaching experience facilitated the transfer of acquired teaching skills to real life. © The Author(s) 2024
Klasik makine öğrenme algoritmaları ve transformer modeli ile Türkçe tweet duygu analizi
Get PDFTeknolojik çağın başlamasıyla birlikte birçok uygulama günümüzde popüler hale gelmiştir. Bunlardan biri de Twitter'dır (Yeni adıyla X). Bu platform sayesinde birçok kullanıcı kişisel düşünce ve fikirlerini yazıyla, resimle ya da video ile paylaşabilmektedir. Paylaşılan bu veriler birçok insanın ilgisini çekmektedir. Bu verilerden kişisel çıkarım yapmak isteyen bilim insanınları, akademisyen ya da başka bir meslek grubundan insanlar çalışmalarını bu yönde yapmaktadır. Örneğin suçlu profili oluşturmak isteyen bir polis twitlerden bunu yapma amacıyla çalışma yürütebilir ya da bir reklam ajansı kişinin yazdıklarına ya da paylaştığı resimlere bakarak kişiye özel reklam üretebilir ve bu sayede ürün satıcıları ürünlerini hızlı bir şekilde satabilir. Bu tezde ise yüksek oranda doğruluk oranı aldığımız bir duygu analizi çalışması yapılmıştır. Bu çalışmada hazır bir Türkçe Tweet verisi üzerinden duygu sınıflandırılması amaçlandı. Bu veri seti 5 farklı etiketle ayrılmış 4000 veriyi içermektedir. Bu ham veri seti üzerinde ön işleme uygulandı. Ön işlemden geçen veri seti eğitim ve test olarak ayrıldı.

Thanks to this platform, many users can share their personal thoughts and ideas with text, pictures or videos. These shared data attract the attention of many people. Scientists, academicians or other professionals who want to make personal inferences from these data do their work in this direction. For example, a police officer who wants to create a criminal profile can use tweets to do this, or an advertising agency can create personalized advertisements by looking at what a person writes or the pictures he/she shares, and thus product sellers can sell their products quickly. In this thesis, a sentiment analysis study was conducted in which we received a high accuracy rate. In this study, it was aimed to classify emotions using a ready-made Turkish Tweet data. This data set includes 4000 data which is separated by 5 different labels. Pre-processing was applied on this raw dataset. The pre-processed dataset was divided into training and testing. Performances were measured with classical machine learning models. These performances were measured in terms of accuracy, precision, recall, and F1 score as well as macro and weighted averages. Additionally, the confusion matrix calculated for each algorithm is given. The Stack algorithm achieved the highest accuracy rate of 96.88%. Also in this study, a pre-trained Transformer model, which is in the field of deep learning, was also used. The data set is divided into training, validation and testing. Likewise, its performance was measured in terms of accuracy, precision, recall and F1 score, and the confusion matrix calculated for each algorithm is given. 93% accuracy rate was achieved with this model
Training and coaching early childhood teachers to foster social, emotional, and behavioral competence of children in Turkey
No full textA growing evidence base demonstrates the effectiveness of teacher training and coaching interventions to improve teacher- and child-level outcomes in high-income countries. However, more information is needed to show the benefits of these interventions in low- and middle-income countries (LMICs). To provide an evidence base for LMICs, we conducted a cluster-randomized controlled trial examining the efficacy of a teacher training and coaching intervention for promoting children’s social, emotional, and behavioral competence, Reaching Educators and Children (REACH) Classroom Check-Up (CCU), on teachers’ behaviors, teacher–child relationship quality, and children’s social competence and problem behaviors. Participants included 20 early childhood teachers and 175 children (4–6 year olds) in Turkey. Findings indicate that REACH CCU increased teachers’ positive behaviors and teacher behaviors that support social, emotional, and behavioral competence of children, while reducing teachers’ negative behaviors. Teachers in REACH CCU demonstrated an increased level of closeness and reduced levels of conflict with children in their classrooms. Furthermore, REACH CCU improved teacher-reported social competence and reduced problem behaviors of children. Results provide evidence that REACH CCU is a promising approach for improving teachers’ behaviors, teacher–child relationship quality, and children’s social, emotional, and behavioral competence, especially in LMICs. © 2024 American Psychological Associatio
A meta-analysis of applied behavior analysis-based ınterventions for ındividuals with autism spectrum disorders (asd) in Turkey
No full textInterventions based on the principles of applied behavior analysis (ABA) have been determined to be evidenced-based practices and are widely used with individuals with autism spectrum disorders (ASD) across the world. Originally developed in the USA, implementation of these interventions has become widespread in the last decade in Turkey. Given the significance of culture in guiding ABA practices, this meta-analysis investigated the prevalence and the magnitude effects of ABA-based interventions and whether specific participant and intervention characteristics moderated such effects in Turkey. Seventy-one ABA-based intervention studies were assessed based on What Works Clearinghouse (WWC, Kratochwill et al., Remedial and Special Education, 34(1), 26–38, 2013) design standards (DSs) including (a) systematic manipulation of independent variables, (b) interrater reliability, (c) three demonstrations of the intervention effect, and (d) adequate number of data points collected for each condition. Forty-three studies that met WWC (Kratochwill et al., Remedial and Special Education, 34(1), 26–38, 2013) DSs were analyzed and calculated with baseline-corrected tau (Tarlow, Behavior Modification, 41(4), 427–467, 2017). Furthermore, performance-criteria-based effect size values (PCES; Aydin and Tanious, Journal of Applied Behavior Analysis, 2021) were calculated for 27 studies that had mastery criteria. While the overall tau appeared to be large 0.71 (p = 0.072, se = 0.254), the overall effect size for PCES revealed a small effect of 0.73. The comparisons of all sub-categories’ effect sizes of moderator variables were not statistically significant based on Kruskal Wallis or Mann Whitney U tests. Additionally, findings revealed that studies were predominantly implemented by highly trained researchers in segregated one-on-one settings, and did not include adults with ASD nor challenging behavior. Overall, there has been significant growth in ABA-based interventions in Turkey that show promise in improving the lives of individuals with ASD. However, further research and cultural considerations are essential for a comprehensive understanding of their impact in the Turkish context. Findings from two different effect size analyses and recommendations for future studies are discussed. © 2024, This is a U.S. Government work and not under copyright protection in the US; foreign copyright protection may apply

This dissertation explores the complex relationships between green supply chain practices, green innovation, green manufacturing and firm performance in the context of contemporary business environments. Based on extensive empirical research and theoretical frameworks, this study provides a comprehensive analysis of the mediating effects of green innovation and green manufacturing on the relationship between green supply chain practices and various dimensions of firm performance. The findings reveal significant positive relationships between green supply chain management practices and both green innovation and green manufacturing, pointing to their important role in promoting sustainable innovation and production processes. Moreover, green supply chain management practices show a positive impact on environmental, economic and operational performance, highlighting their multifaceted benefits for firms operating in environmentally sensitive markets. Similarly, green supply chain management practices exhibit positive relationships with operational performance and underscore the importance of integrating sustainable practices into business operations to achieve efficiency gains. Moreover, the mediating role of green innovation in improving environmental and operational performance emphasizes its mediating function in translating sustainable practices into tangible business outcomes. Contrary to expectations, the study did not find a significant mediating role of green manufacturing in the relationship between green supply chain management practices and environmental performance. However, green manufacturing shows direct positive effects on environmental, economic and operational performance, emphasizing its intrinsic value in achieving sustainability across different organizational functions. Overall, this thesis contributes to the growing body of knowledge on sustainable supply chain management by elucidating the mechanisms through which green innovation and green manufacturing mediate the impact of green supply chain practices on firm performance. These insights offer practical implications for firms seeking to leverage sustainability as a strategic imperative for long-term competitiveness and environmental stewardship

The effect of pulmonary rehabilitation on quality of life and functional capacity after chemotherapy in patients with small cell lung cancer
No full textObjective: This study aimed to investigate the effect of pulmonary rehabilitation on quality of life during the survival period in individuals with small cell lung cancer. Methods: Thirty-six patients with a diagnosis of small cell lung cancer (SCLC), who completed chemotherapy treatment and were in the survival period, were included in the study. A pulmonary rehabilitation program was applied to individuals at 40–70% of submaximal heart rate, 3 days a week for 8 weeks. The pulmonary rehabilitation program will consist of warm up, breathing exercises, gait training, aerobic exercises, and cool down exercises. Demographic information, walking distance, and presence of dyspnea were questioned. Inspiration/expiration difference was evaluated. Vital signs were evaluated before each session. Quality of life was assessed with the Cancer-Specific Developed Quality of Life Scale (EORTC-QLQ-C30). Results: Of the patients, 80% (36 people) completed the entire 8-week program. The mean age of the individuals was 51.78 ± 10.23. In the evaluation made at the end of the rehabilitation program, it was observed that the walking distance of the individuals increased significantly. Inspiration of individuals’ expiratory difference increased by an average of 2.01 ± 0.40 cm. Improvement was found in the sub-parameters of quality of life (p < 0.05). Significance of results: The participants with small cell lung cancer had decreased quality of life due to long-term immobilization, surgery, hospitalization times, side effects of chemotherapy treatment, and other problems. Regular exercise programs can provide an increase in the individual’s pulmonary functions. Individual-specific pulmonary rehabilitation programs have important contributions to the quality of life in SCLC on the survival period, and it has shown that this study can guide physiotherapists and physicians working in oncological rehabilitation and pulmonary rehabilitation. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024
Prevalence, risk level and risk factors of diabetic foot ulcer among adult individuals with diabetes in the southeastern anatolia region of Turkiye
Get PDFObjective: The aim of the study was to determine the prevalence, risk, and predisposing factors of diabetic foot ulcers in adults with diabetes. Methods: This study is multi-centered descriptive cross-sectional research. Data were collected between June 2022 and November 2022 in seven cities, including five teaching and research hospitals and two public hospitals. The study included 357 people with diabetes. The sample was selected using stratified and systematic sampling. General demographic characteristics, medical history, laboratory and foot examination results, history of foot ulcer and/or amputation, skin and nail problems, peripheral sensory loss (10 g-Semmes-Weinstein monofilament) and vascular assessment were obtained. Logistic regression analysis was used to screen for factors affecting the diabetic foot. Results: The prevalence of diabetic foot ulcers was 17.1 % (%13.2-%21.5; %95 CI). Among 296 individuals with diabetes without foot ulcers, 86.5 % (256) had risk level 0, 7.3 % (26) had risk level 1, 3.4 % (10) had risk level 2, and 1.4 % (4) had risk level 3. In regression analysis, the variables of peripheral arterial disease (Exp β: 3.781 - P = .027), history of ulcer (Exp β = 26,180 - P < .001), edema (Exp β: 9.784 - P < .001), fungus between the toes (Exp β = 5.284 - p = .009) were associated with a significantly increased risk of developing diabetic foot. Conclusion: The prevalence of diabetic foot ulcers was found to be approximately two out of every 10 patients with diabetes, and peripheral arterial disease, history of ulcers, edema, and presence of fungus between the toes were found to be among the risks predicting diabetic foot. All diabetic individuals should be diagnosed in terms of diabetic foot risk factors, and follow-up and treatment should be planned considering the basic building blocks of diabetic foot prevention according to the determined risk group
