Ortaokul 7. sınıf fen bilimleri dersi kuvvet ve enerji ünitesinin kavram karikatürleri ile öğretiminin öğrencilerin kavramsal anlama seviyelerine ve akademik başarılarına etkisi
(Cumhuriyet Üniversitesi Eğitim Fakültesi, 2025) Kaymaz, Sevim; Eryılmaz Muştu, Özlem
Günümüzde hızlı artan bilgiler ile eğitim anlayışında değişiklikler yaşanmıştır. Artık öğrenciler öğretim süreçlerine aktif katılmakta, olayları sorgulamakta ve bilgileri yapılandırabilmektedirler. Fen öğretiminde kullanılan tekniklerden biri de kavram karikatürleridir. Bu çalışmada ortaokul 7. sınıf fen bilimleri dersi “Kuvvet ve Enerji” ünitesinin kavram karikatürleri ile öğretiminin öğrencilerin akademik başarıları ve kavramsal anlama seviyelerine etkisini belirlemek amaçlanmıştır. Bu araştırmanın örneklemini Konya ili Cihanbeyli ilçesindeki bir devlet ortaokulunda öğrenim görmekte olan 7. sınıf öğrencilerinden 20 kişi oluşturmaktadır. Çalışmada nicel araştırma yöntemlerinden yarı deneysel araştırma modellerinden biri olan kontrol gruplu öntest-sontest desen kullanılmıştır. Veri toplama aracı olarak “Kuvvet ve Hareket Akademik Başarı Testi” ve “Kuvvet ve Hareket Konusu Kavram Testi” kullanılmıştır. Kontrol grubuna fen bilimleri öğretim programı, deney grubunda da öğretim programı kavram karikatürleri ile desteklenerek 5 (beş) haftalık bir öğretim uygulanmıştır. Beş hafta süren öğretim bittikten sonra öğretim öncesinde uygulanan testler sontest olarak tekrar öğrencilere uygulanmıştır. Çalışmada elde edilen verilerin analizi sonrasında kontrol ve deney grubunun hem akademik başarı puanları hem de kavram testi puanları arasında istatistiksel olarak anlamlı sonuçlar bulunmuştur.
Integration of bluetooth technology and artificial neural networks in high accuracy indoor positioning
(IGI Global, 2025) Coşgun, Atıl Emre
Nowadays, with the increasing digitalization and widespread use of Internet of Things (IoT) applications, accurate and reliable indoor positioning system applications have become increasingly important. With the increasing need in the areas of use, researchers have proposed various indoor positioning system technologies and methods. In this context, Bluetooth Low Energy (BLE) technology offers a cost-effective, energy-efficient, and easy-to-integrate solution within existing infrastructures. The integration of BLE technology and ANNs for indoor positioning will be the subject of this section, which will cover the theoretical basis and practical applications. A comprehensive review of BLE-based positioning algorithms, performance evaluations, and the design and training of ANN models will be presented. In addition, the limitations of existing systems will be highlighted through the examination of the challenges. The aim of this study is to make a meaningful contribution to the field of indoor positioning and to provide applicable solutions in both academic and industrial environments.
A portfolio-focused behavioral model linking financial literacy and risk tolerance: evidence from mutual fund investors in Türkiye
(Borsa Istanbul Anonim Sirketi, 2025) Hamurcu, Çağrı; Hazar, Adalet; Babuşcu, Şenol
This study develops a portfolio-focused behavioral model to investigate how the multidimensional components of financial literacy—knowledge, attitude, and behavior—shape financial risk tolerance among mutual fund investors in Türkiye. Whereas most papers evaluate the influence of financial literacy on investment decisions using broad investor samples, this study centers on individuals who make professionally managed, portfolio-based investment decisions, thereby making a contribution to the literature. Mutual fund investors typically have higher financial awareness and structured decision-making processes, enabling a more nuanced analysis of the impact of financial literacy dimensions on risk tolerance. Drawing on behavioral finance, financial capability theory, and the theory of planned behavior, the model traces direct and indirect paths from literacy components to risk preferences. Based on data from 703 Turkish mutual fund investors and using validated Organization for Economic Cooperation and Development (OECD)/International Network on Financial Education (INFE) and Grable-Lytton scales, our structural equation model (SEM) reveals that financial behavior is the primary driver of risk tolerance, mediating the influence of knowledge and attitudes. These findings emphasize that financial literacy translates into risk-related decision-making primarily through behavior. The study highlights the behavioral dynamics of financial capability in emerging markets and calls for financial education programs that go beyond knowledge transfer to cultivate actionable attitudes and proactive behaviors among informed investors.
Can financial literacy training improve financially responsible behavior? experimental evidence from turkish undergraduates
(Borsa Istanbul Anonim Sirketi, 2025) İlbasmış, Metin; Altın, Hakan; Yılmaz, Büşra
This study examines the causal impact of financial literacy education on financially responsible behavior using a quasi-experimental design among 125 undergraduate students in Türkiye. The study compares outcomes between a treatment group that received structured financial literacy training and a control group that did not. The results show that even a brief educational intervention significantly enhances objective financial literacy and leads to more prudent financial behaviors, including budgeting, saving, purchasing insurance, and investment planning. By addressing endogeneity concerns and targeting individuals at a critical decision-making stage of life, this study provides empirical evidence of the effectiveness of financial education, offering valuable insights for policy development in emerging market contexts.
Environmental variation in the bioclimatic niche, hibernation patterns, and body size of anatolian ground squirrels
(Springer Nature, 2025) Kart Gür, Mutlu; Kankılıç, Tolga; Gür, Hakan
Environmental variation in phenotypic traits offers key insights into how organisms adapt to diverse environmental conditions. In this study, we studied how diverse environmental conditions shape environmental variation in the bioclimatic niche, hibernation patterns, and body size of Anatolian ground squirrels (Spermophilus xanthoprymnus). Specifically, we used presence data from across the species’ range, body temperature data from 51 free-living individuals in two natural populations located 880 km apart, and body size data from 167 individuals across 10 populations to explore environmental variation in bioclimatic niche, hibernation patterns, and body size across elevational and associated climatic gradients. Our results indicate that the bioclimatic niches of two deeply divergent mitochondrial (mt)DNA lineages (i.e., the western and eastern lineages) are not equivalent. However, this pattern appears to result from the underlying bioclimatic differences between the regions the western and eastern lineages inhabit. Anatolian ground squirrels from the eastern population, which inhabits a higher-elevation, colder, wetter, and more seasonally variable environment, exhibit longer hibernation periods, spend a higher proportion of this period in torpor bouts, and achieve deeper reductions in body temperature than conspecifics from the western population. Additionally, adult males exhibit shorter hibernation periods and spend a smaller proportion of this period in torpor bouts than the other age-sex classes. Anatolian ground squirrels from the eastern lineage, which inhabits areas at higher elevations with colder, wetter, and more seasonally variable environments, are morphologically larger than conspecifics from the western lineage, particularly among males. Overall, our results demonstrate that elevational and climatic gradients shape phenotypic variation in Anatolian ground squirrels through lineage-, population- and demographic-level responses. By integrating bioclimatic niche, hibernation patterns, and body size, this study highlights the importance of combining multiple trait dimensions to improve our understanding of eco-evolutionary divergence in hibernating mammals.
