INTERACTION BETWEEN ACADEMIC RESILIENCE AND ACADEMIC ACHIEVEMENT OF TEACHER TRAINEES

This study sought to explore the interaction between academic resilience and academic achievement as measured by Grade Point Average (GPA). To this end, the Academic Resilience Scale (Cassidy, 2016) consisting of 30 items and scored on a 5-point Likert scale was administered. The overall reliability of the scale was .79 and the reliability coefficients for the three sub-scales were above .70. Student GPAs (M= 2.50, SD= .51) were procured by a self-report item. The sample of the study consisted of 198 preservice English language teachers at a foundation university in Turkey. Descriptive results showed that participants scored highest on reflecting and adaptive help-seeking (M= 3.77, SD= .58). It was followed by perseverance (M= 3.44, SD= .41) and negative affect and emotional response (M= 2.90, SD= .69) dimensions. Moreover, positive correlations were revealed between GPA and perseverance (r= .20, p <.05) and reflecting and adaptive help-seeking (r= .37, p<.01). The results of the multiple regression analysis manifested reflecting and adaptive help-seeking to be the only significant predictor of GPA

Examining the Conceptual and Procedural Knowledge Levels of Engineering Faculty Students on the Integral of a Two-Variable Function

In this study, the focus will be on the concept of integral in two-variable functions, which holds great significance not only in mathematics but also in fields related to science and engineering in terms of learning and teaching. The integral of a two-variable function is a fundamental concept in mathematics with broad applications in science and engineering. This study addresses the vital role of this concept in shaping the foundational knowledge of engineering faculty students. The ability to comprehend and apply integrals is crucial not only for mathematical proficiency but also for success in various scientific and engineering disciplines. Within this scope, the study aims to examine the domain knowledge of engineering faculty students regarding the integral concept in terms of conceptual and procedural knowledge. This research was structured as a case study with twenty engineering faculty students selected according to critical case sampling. Participants were administered a questionnaire consisting of 10 questions to assess their knowledge of the integral of two-variable functions and in-depth insights into their conceptual and procedural knowledge of the topic were obtained. According to the results of data analysis, it was revealed that engineering faculty students possess procedural knowledge about the integral concept but have conceptual deficiencies and cannot explain their answers based on procedural knowledge. Furthermore, it was determined that conceptual knowledge is more inadequate compared to procedural knowledge. Therefore, developing content that aims to strengthen the integral topic both procedurally and conceptually in undergraduate-level Analysis courses is recommended.

The interplay between academic motivation and academic achievement of teacher trainees

The aim of this study was to research the interaction between academic motivation and academic achievement. In this regard, the Academic Motivation Scale (Vallerand et al, 1992) and a student background questionnaire were administered to 195 Turkish teacher trainees of English at a foundation university in Ankara, Turkey. Descriptive results showed that prospective teachers were mainly extrinsically motivated, followed by intrinsic motivation. Moreover, they had quite low on amotivation scores. Significant gender differences were revealed in introjected regulation and intrinsic motivation for accomplishment with prospective female teachers reporting significantly higher levels on both. A negative correlation was found between GPA and amotivation and a positive one between GPA and intrinsic motivation for knowledge. Furthermore, the multiple regression analysis uncovered amotivation as the only predictor of GPA

THE RELATIONSHIP BETWEEN STUDENT ENGAGEMENT AND TERTIARY LEVEL ENGLISH LANGUAGE LEARNERS’ ACHIEVEMENT

The aim of this study was to investigate the interaction between student engagement and achievement. The study sample was composed of 296 at Ufuk University in Ankara, Turkey. The participants were enrolled in the intensive English language program of the foreign language Preparatory School of the institution. Data collection was carried out with the Mazer’s (2012) Student Engagement Scale, which was adapted to Turkish by Uğur and Akın (2015). Students’ English achievement was measured by their mid-term exam results. Statistical analysis revealed participants to be more engaged in silent in class behaviors followed by out of class behaviors, thinking about course content, and out-of-class behaviors. Moreover, it was found that participants had low engagement levels in oral in class behaviors. All types of engagement had a positive correlation with mid-term exam scores. Among all types of engagement behaviors, oral in class behaviors was the only predictor of students’ exam scores. Keywords: student engagement, achievement, foreign language learnin

The Relationship Between Financial Development and Economic Growth: Evidence From Brics Countries and Turkey

DergiPark: 829906trakyaiibfThe aim of this paper is to analyze the link and the direction of the relationship between financial development and economic growth in Turkey and BRICS countries for the period of 1994-2011. Moreover, the paper di- vides the financial market into two sub-markets as banking sector and stock market to examine their individual impact on economic growth. Fixed effect panel regression method and a relatively new panel causality technique, namely Dimutrescu-Hurlin test is applied to estimate the existence of the causal link between financial development and economic growth. The results of the analysis show that there is neither linear nor causal link for stock mar- ket development and economic growth, while statistically significant relationship exists between banking sector development and economic growth in the direction of economic growth to banking sector. In a nutshell, the results suggest an evidence for demand-following pattern in Turkey and BRICS Countries

DergiPark: 829902trakyaiibfİşgücü piyasasındaki cinsiyet ayrımcılığı benzer yeteneklere, eğitime ve tecrübeye sahip olan işçi gruplarının diğer cinsiyetle karşılaştırıldığında üretkenliklerine bakılmaksızın istihdamda, işe erişimde, terfide veya ücretlerinde ikinci sınıf muamele görmeleri olarak tanımlanmaktadır. Bu makale mesleki cinsiyet ayrımcılığının altında yatan beşeri sermaye donatısı, endüstriyel ve mesleki ayrımcılık gibi nedenleri saptamayı amaçladığı gibi özel sektör-kamu sektörü ayrımı firma boyutu ve sosyal güvenlik gibi kurumsal faktörleri de göz önünde bulundurmaktadır. Çalışmada teorik ve ampirik cinsiyet ayrımcılığı literatürü de incelenmiştir ve Türkiye gibi geleneksel, kültürel inançların ve normların hala dominant olduğu gelişmekte olan ülkelerde cinsiyet ayrımcılığının önemi değerlendirilmiştir. Bu makale kapsamında ayrımcılık endeksi hesaplanmıştır ayrıca cinsiyet tabanlı endüstriyel ve mesleki ayrımcılığın düzeyi elde edilen veri seti çerçevesinde araştırılmıştır. Yapılan araştırma bulgularına göre cinsiyetler arasındaki ücret farklılıkları büyük oranda cinsiyet bazlı mesleki ve endüstriyel ayrımcılıktan ayrıca özel sektör-kamu sektörü ayrımı gibi kurumsal farklılıklardan kaynaklanmaktadır. Bunun yanında bu çalışma ile tanımlanmamış cinsiyet ayrımcılığının üstesinden gelebilmek için emek piyasasındaki ayrımcı çalışma şartlarının da ortadan kalkması gerektiği anlaşılmaktadır

Fabrication, characterization and simulation of plasmonic cavities

Ankara : The Department of Physics and the Institute of Engineering and Science of Bilkent University, 2010.Thesis (Master's) -- Bilkent University, 2010.Includes bibliographical references leaves 67-73.Surface plasmon polaritons (SPPs) originate from the collective oscillations of conduction electrons coupled with photons propagating at metal-dielectric interfaces. A uniform metallic gratings change the dispersion (energy-momentum relation) of a flat metal surfaces due to the interaction of SPPs with the periodic structure. By breaking the symmetry of the periodic plasmonic structure, SPP cavities can be achieved and SPPs can be localized inside the cavity regions. The aim of this thesis is to understand the physics of phase shifted grating based plasmonic cavities. To this end, we fabricated uniform gratings and phase shifted gratings using electron beam lithography, and optically characterized these SPP structures with polarization dependent reflection spectroscopy. We verified experimental results with numerical simulations SPP propagation and localization on the grating structures. Dispersion curves of SPPs have been calculated by solving Maxwell’s wave equations using finite difference time domain method (FDTD) with appropriate boundary conditions in agreement with experimentally obtained data. We studied the dispersion curve as a function of grating profile modulation where we vary the ridge height and width of the ridges. We find that the plasmonic band gap width increases as the ridge height of the ridges in the grating increases. Optimum duty cycle of grating to observe plasmonic band gap is determined to be half of the grating period. Amount of the phase shift added to the periodicity of the uniform grating defines the energy of the cavity state, which is periodically related to the phase shift. A plasmonic cavity with a quality factor 80 has been achieved. The propagation mechanism of SPPs on coupled cavities is plasmon hopping from a given cavity to the next one.Karabıyık, MustafaM.S

Pollen quality, pollen production and yield of some tomato (Solanum lycopersicum) genotypes under high temperature stress in Eastern Mediterranean

Pollen quality, pollen production and yield of different high temperature tolerant tomato genotypes were evaluated under Adana, Turkey conditions in two different periods. The control treatment (normal sown, where day/night temperatures during the vegetative and generative stage are below 32/20 degrees C) of the first period started on February 20, 2015. The seedlings in the second period were planted on May 15, 2015. The performances of twenty-four tomato genotypes (resistant and sensitive commercial genotypes) were compared to determine high temperature resistant and sensitive tomato genotypes. Significant relationship was obtained between the yield and the number of pollens. The results of the experiment revealed that 'Tom173', 'Tom119' and 'T15656' genotypes were more resistant, while 'Tom108' and 'Tom10' genotypes were more sensitive compared to the other tomato genotypes tested in the experiment
