Analysis of self-regulated learning strategies used by online learners
(SAGE Publications Inc., 2024) Öztürk, Mücahit; Mıhcı Türker, Pınar
This study is a qualitative survey research that examines the self-regulated learning strategies used by students in the blended online learning process. Participants were made up of 67 pre-service teachers studying at a faculty of education. A questionnaire form was used to determine students’ self-regulated learning strategies. The self-regulated learning strategies were classified under three themes: before the lesson, during the lesson, and after the lesson. The strategies used before the lessons were organizing the environment, planning, motivating oneself, and physiological and psychological readiness. During the online lessons, students used strategies such as taking notes, attention focusing, help seeking, effort management, self-discipline, taking a break, and time management. After the lessons, students used strategies such as reviewing records, organizing and transforming, practicing, working with additional resources, help seeking, self-testing, and completing tasks. Furthermore, the study results that were revealed to be different from the results of similar studies were discussed and recommendations for future studies were made. In addition, the study revealed that the strategies used by the students differed according to their communication modes. While synchronous and blended groups used more self-regulated learning strategies, asynchronous students used less self-regulated learning strategies.
Microanalytic evaluation of students’ self-regulated learning in flipped EFL instruction
(Springer, 2023) Çakiroğlu, Ünal; Öztürk, Mücahit
The aim of this study is to examine the development of self-regulated learning (SRL) of university students in an EFL course via Flipped classroom through a novel measurement roadmap. Microanalytic techniques were used throughout the process rather than students’ perceptions at a given moment. SRL skills scores are reported as well as sample testimonies from students as qualitative data used to explain the analytic measures. The study was conducted with 12 students studying at a public university and lasted for 6 weeks. A new system FCMWEB is designed throughout to monitor online SRL development taking Zimmerman (2008) SRL model as a basis. While the forethought phase was monitored in the online sessions and the performance and self-reflection phase were associated with the face-to-face sessions. Records from FCMWEB as microanalytic, worksheet, observation notes and self-reflection form were used as data collection tools. During the study, the sub skills of forethought phase, self-reflection phase and performance phase are analyzed and validated through students’ perspectives. The developments in the skills of the forethought and self-reflection phases were between sufficient and advanced levels. The performance phase was mostly sufficient, but also included poor and advanced levels. The results provide implications for course designers and instructors who desire to provide a better flipped classroom experience in EFL for university students.

Nicel araştırma yöntemine göre tasarlanan bu çalışmada tarama deseni kullanılmıştır. Araştırmanın evren ve örneklemini 2021-2022 eğitim-öğretim yılında Aksaray Üniversitesi İİBF ile Ortaköy MYO’da öğrenim gören öğrenciler oluşturmaktadır. Toplanan verilerin analizinde non-parametrik testlerden faydalanılmıştır. Araştırma verileri ile yapılan analizler sonucunda; üniversite öğrencilerinin Siber İnsani Değer (SİD) puan ortalamaları dikkate alındığında, katılımcıların tutum ve davranışlarının insani değer merkezli olduğu, kadın ve erkek öğrencilerin sosyal medya mecrasında insani değerler bakımından benzer hassasiyete sahip oldukları belirlenmiştir. Ayrıca, öğrencilerin sosyal medya bağımlısı oldukları, sosyal medyada insani ve etik değerlerle bağdaşmayan paylaşımların yaygınlığına karşın, siber insani değerler konusunda oldukça hassas oldukları tespit edilmiştir. Öğrencilerin cinsiyet, yaş, öğrenim gördükleri birim ve sınıf düzeyi değişkenlerine göre siber insani değer puan dağılımları arasında anlamlı bir fark olmadığı tespit edilmiştir.
Smartphone and internet addiction as predictors of cyberloafing levels in students: A mediated model
(IOS Press BV, 2022) Öztürk, Mücahit; Kerse, Gökhan
This study aims to determine the predictors of cyberloafing behaviors of university students. In this context, we examined the effects of smartphone and internet addiction variables on cyberloafing levels. Besides, the mediator effect of internet addiction was determined in the impact of smartphone addiction on cyberloafing. We conducted the questionnaire-based study with 341 students studying at different departments of a state university (faculty of education, faculty of engineering, and vocational school) in Turkey. Participants consisted of 182 male and 159 female. Students filled out the smartphone addiction scale, the internet addiction scale, and the cyberloafing activities scale. The data obtained from the 5-point Likert type scales were evaluated with correlation and regression analyses. The results showed that there is a significant positive relationship between smartphone addiction, internet addiction, and cyberloafing. While internet addiction was a predictor of cyberloafing, it mediated the effect of smartphone addiction on cyberloafing. We discussed the results of this study and offered suggestions for future research.
The effects on thermal efficiency of yttria-stabilized zirconia and lanthanum zirconate-based thermal barrier coatings on aluminum heating block for 3D printer
(MDPI AG, 2021) Demir, Hasan
Fused filament fabrication is an important additive manufacturing method, for which 3D printers are the most commonly used printing tools. In this method, there are many factors that affect the printing quality, chief among which is temperature. The fusion temperature of the material is created by an aluminum heating block in the extruder. Stability and a constant temperature for the aluminum heating block are inevitable requirements for print quality. This study aims to use the thermal barrier coating method to increase the thermal efficiency and stability of the aluminum heating block by reducing heat loss. Furthermore, it aims to perform steady-state thermal analysis using finite element analysis software. The analyses are carried out in stagnant air environment and at the printing temperature of acrylonitrile butadiene styrene material. In order to examine the effects of different coating materials, blocks coated with two different coating materials, as well as uncoated blocks, were used in the analyses. The coating made with yttria-stabilized zirconia and pyrochlore-type lanthanum zirconate materials, together with the NiCRAl bond layer, prevent temperature fluctuation by preventing heat loss. The effects of the coating method on average heat flux density, temperature distribution of blocks, and temperature distribution of the filament tube hole were investigated. Additionally, changes in flow velocity were determined by examining the effects of the thermal barrier coating method on temperature distribution. The average heat flux density in the coated blocks decreased by 10.258%. Throughout the investigation, the temperature distributions in the coated blocks became homogeneous. It was also observed that both coating materials produce the same effect. This article performs a steady-state thermal analysis of a conventional model and thermal-barrier-coated models to increase print quality by reducing heat loss from the aluminum heating block.

Turkey is located in unique geographic position and it is like a bridge between the continents of Asia and Europe. Besides this, it lying partly between 36°–42° NL and 26°–45° EL in the Northern Hemisphere. Turkey has total surface area 780,043 km2 and its land use areas’ 31.1% is agricultural lands. Turkey Statistical Institute (TUIK) state that Turkey's population is 83.155 million in 2020. Population growth rate of country is 13.9% as annually. On account of Turkey’ vary topographical characteristics, it has available many climate zones. These are Mediterranean Climate that is hot, dry summers and rainy, mild winters, the Black Sea Climate that is although in the coastal area cool summer and warm winters, snowy the higher parts climate is snowy and cold, also the Terrestrial Climate have high temperature differences between day and night-summer and winter. In addition to the Marmara Climate shows all of above side climate characteristics due to transition between the Terrestrial, Black Sea and Mediterranean climates. Turkey is situated in a geography quite lucky in terms of solar energy. Although it is geographically well located, it is limited in terms of agricultural land. Agrivoltaic systems are a good concept in terms of expanding the agricultural lands and increasing the efficiency of the produced electricity from solar systems. Agrivoltaic system is a kind of term or method which is combination of growing crops and producing electricity on the same land. In solar plant, to produce 1 MW electricity requires approximately 20.000 m2 land. The total installed capacity is 6493 MW of Solar Power Plants in 2019, in Turkey. When calculated require area to total produce capacity in Turkey, it is obtained that approximately 130 km2 area is needed. In addition, in term of the suitable agricultural products to be grown are vegetables between the PV panel arrays and 25% of agricultural crops produced in Turkey are vegetables.

A valid and reliable scale for developing programming-oriented computational thinking
(SAGE Publications, 2021) Kılıç, Servet; Gökoğlu, Seyfullah; Öztürk, Mücahit
In this research, a scale was developed to determine the programming-oriented computational thinking skills of university students. The participants were 360 students studying in various departments at different universities in Turkey for computer programming. The scale consists of 33 items under conceptual knowledge, algorithmic thinking, and evaluation subscale. While there was no significant difference between the students' conceptual knowledge and algorithmic thinking skills, the evaluation skills of male students differed significantly compared to females. Programming experience has a significant effect on conceptual knowledge, algorithmic thinking, and evaluation. The algorithmic thinking skills of the students who have low, middle, and high-level programming experience differed significantly. In terms of the development of conceptual knowledge and evaluation skills, it was observed that students should have at least one year of programming experience, but this experience will not make a significant difference if it is four years or more. It is thought that this scale, which is structured for different applications (e.g., web, game, robot) and learning environments (e.g., text, block) within the framework of its programming capabilities (conceptual, semantic, strategic knowledge), will contribute significantly to the evaluation of computational thinking as programming oriented.

Son yıllarda yükseköğretimde yaygınlaşmaya başlayan Ters yüz sınıf modeli (TYS), öğrencilerin evde etkileşimli teknolojiler aracılığıyla ders içeriğini öğrendikleri, yüz yüze öğrenme ortamında ise öğrenci merkezli etkinlikler ile öğrenilen bilgilerin uygulanmasını yapabilecekleri bir modeldir. Bu araştırmanın amacı TYS modeliyle tasarlanan öğrenme ortamında öğrencilerin öz-düzenleyici öğrenme berilerinin düzeyini belirleyerek akademik başarıları ile öz-düzenleyici öğrenme arasındaki ilişkiyi incelemektir. Araştırma bir devlet üniversitesinin MYO Muhasebe bölümünde öğrenim gören 24 öğrenciyle haftada 4 saat olarak işlenen Yabancı Dil dersinde yürütülmüştür. Araştırmanın sonunda TYS modeliyle tasarlanan öğrenme ortamında öğrencilerin amaç belirleme, ortam düzenleme, görev stratejileri ve özdeğerlendirmesinin yüksek düzeyde; zaman yönetimi ve yardım arama düzeyinin orta düzeyde geliştiği belirlenmiştir. Öğrencilerin akademik başarıları ile görev stratejileri, öz-değerlendirme ve öz-düzenleyici öğrenme toplam puanları arasında güçlü ilişki görülmüştür. Diğer taraftan öğrencilerin, akademik başarıları ile amaç belirleme ve ortam düzenleme arasında orta düzeyde ilişki ortaya çıkmıştır. Öğrencilerin akademik başarıları ile zaman yönetimi ve yardım arama becerileri arasında zayıf ilişki belirlenmiştir. Çalışmanın yabancıl dil derslerinde TYS modeli uygulamaları için tasarım ve uygulayıcılara öz-düzenleyici öğrenmeyi belirleme ve geliştirme yönüyle örnek olabileceği düşünülmektedir.
Design and trajectory control of universal drone system
(Elsevier, 2019) Yıldırım, Şahin; Çabuk, Nihat; Bakırcıoğlu, Veli
In this paper, a new universal drone design is proposed to be used in different applications. The drone system has a variable number of rotors from four to twelve with portable arms. As a comparative study, a conventional eight rotors (Octocopter) and independently controlled twelve rotors (Dodecacopter) configures are chosen for the proposed universal drone simulations to benchmark the trajectory performance. Besides, since the arm lengths can be changed in this drone system, the effect of different arm lengths on this performance is also examined. The comparisons are performed on both systems in five different working condition, such as without disturbance, with periodic disturbances and non-periodic disturbances. In the simulations, when the amplitude was increased by 100% under periodic disturbing effect, an increase of 69.7% and 47.6% was observed in the root mean square of the position errors of the Octocopter and Dodecacopter systems, respectively. Similarly, for non-periodic disturbances, an increase of %13 and %7 was observed for both systems, respectively. According to the obtained results, the octocopter system is partially more stable without disturbing effect while the dodecacopter system is more stable flight than octocopter systems as the disturbance effect increases.

(Assoc Learning Technology-Alt, 2018) Çakıroğlu, Unal; Suiçmez, S. Sude; Kurtoğlu, Yılmaz B.; Sarı, Ayhan; Yıldız, Şuheda; Özturk, Mücahit
The purpose of this study is to investigate the perceived cognitive load and its effects on the academic performance in Scratch-based programming. The four main concepts of programming (sequences, operators, conditions and loop) were delivered in the instructional package. Participants were 12 sixth-grade students enrolled at a public secondary school. The results from quantitative and qualitative instruments indicated that students' perceived cognitive loads were close to each other among four programming concepts. The attractive interface of Scratch was somewhat useful but some parts of the interface were problematic for achieving the programming tasks. This study concludes with suggestions for Scratch practitioners and researchers to pay attention to the sources of cognitive load effects.
Flipped classroom with problem based activities: Exploring self-regulated learning in a programming language course
(International Forum of Educational Technology and Society, 2017) Çakıroğlu, Ünal; Öztürk, Mücahit
This study intended to explore the development of self-regulation in a flipped classroom setting. Problem based learning activities were carried out in flipped classrooms to promote self-regulation. A total of 30 undergraduate students from Mechatronic department participated in the study. Self-regulation skills were discussed through students' and the instructor's experiences including their opinions and behaviours. Qualitative data was collected with an observation form, discussion messages and interviews with selected participants. As a result, in terms of self-regulated learning, the goal setting and planning, task strategies and help seeking skills of the students were high in the face to face learning designed with problem based activities through flipped classroom model, their goal setting and planning, task strategies and help seeking skills were appeared moderately. In the home sessions, environment structuring, goal setting and planning skills were developed in high level while task strategies, help seeking, time management, monitoring, selfefficacy and self-evaluation skills were moderate and monitoring skills was lower. Consequently, it is hoped that the study may provide some suggestions for using problem based activities in flipped learning.
Implementation of elaboration theory in material design for distance education
(Anadolu Üniversitesi, 2014) Çakıroğlu, Ünal; Öztürk, Mücahit
Distance Education is a kind of teaching in which a variety of teaching activities and the communication between students are achieved through peculiarly prepared contents and environments at a certain station in the cases when there is no possibility to conduct in-class activities. One of the most significant constraints of distance education conducted by several universities is the lack of qualified content and the limitations in the presentation of the content. Herein there is a need for reference models that will show how to make material design, constitute an efficient theoretical base for presentation of the course content. Therefore, in this study for material design in Distance Education, Elaboration Theory was employed, and a sample course design was accomplished. With its seven basic components (an Elaborative Sequence, Learning Prerequisite Sequences, Summarizers, Synthesizers, Analogies, Cognitive Strategy Activators, Learner Control) Elaboration Theory guides the teaching designers about how the teaching content and its presentations should be. In this study, a material design including four subjects was conducted for an introductory programming course in the scope of guiding principles of ET, and at every stage of this design, four experts' views were received in order to ensure its validity. The suggested style of material design is hoped to eliminate at a visible level the insufficiencies in favor of synchronous distance learning practices.
