Article Citation - WoS: 12Reliability, Validity and Turkish Adaptation of Self-Directed Learning Scale (Sdls)(2018) Fuçular, Emine Ezgi; Nazlıgül, Merve Denizci; Demircioğlu, Zeynep Işıl; Çevik, Tuğçe; Öge, Burak; Ozcelik, ErolSelf-Directed Learning Scale (SDLS) developed by Lounsbury, Levy, Park, Gibson, and Smith (2009) was used for determining individuals’ self-directed learning. The purpose of this study was to translate the SDLS into Turkish and to investigate its reliability and validity with a sample of 272 university students. The SDLS, the Modified Schutte Emotional Intelligence Scale (MSEIS), Self-Directed Learning Inventory (SDLI), and the Causal Uncertainty Scale (CUS) for determining convergent validity was applied to the participants. Factor analyses results verified the uni-dimensionality of the scale. The test–retest correlation of SDLS was 0.82, whereas Cronbach alpha coefficient of the scale was founded as 0.85 in the reliability analyses. Correlation coefficients representing for convergent validities varied from 0.30 to 0.72 (p < .01) and criterion validity of the scale was determined as 0.236 when cumulative GPA was used as criterion in the assessment of concurrent validity. The findings suggest that the Turkish adaptation of SDLS is a valid and reliable tool to measure self-directed learning in Turkish samplesArticle Citation - WoS: 15Citation - Scopus: 15Construct and Face Validity of the Educational Computer-Based Environment (Ece) Assessment Scenarios for Basic Endoneurosurgery Skills(Springer, 2017) Ozcelik, Erol; Sengul, Gokhan; Berker, Mustafa; Cagiltay, Nergiz ErcilBackground In neurosurgery education, there is a paradigm shift from time-based training to criterion-based model for which competency and assessment becomes very critical. Even virtual reality simulators provide alternatives to improve education and assessment in neurosurgery programs and allow for several objective assessment measures, there are not many tools for assessing the overall performance of trainees. This study aims to develop and validate a tool for assessing the overall performance of participants in a simulation-based endoneurosurgery training environment. Methods A training program was developed in two levels: endoscopy practice and beginning surgical practice based on four scenarios. Then, three experiments were conducted with three corresponding groups of participants (Experiment 1, 45 (32 beginners, 13 experienced), Experiment 2, 53 (40 beginners, 13 experienced), and Experiment 3, 26 (14 novices, 12 intermediate) participants). The results analyzed to understand the common factors among the performance measurements of these experiments. Then, a factor capable of assessing the overall skill levels of surgical residents was extracted. Afterwards, the proposed measure was tested to estimate the experience levels of the participants. Finally, the level of realism of these educational scenarios was assessed. Results The factor formed by time, distance, and accuracy on simulated tasks provided an overall performance indicator. The prediction correctness was very high for the beginners than the one for experienced surgeons in Experiments 1 and 2. When non-dominant hand is used in a surgical procedure-based scenario, skill levels of surgeons can be better predicted. The results indicate that the scenarios in Experiments 1 and 2 can be used as an assessment tool for the beginners, and scenario-2 in Experiment 3 can be used as an assessment tool for intermediate and novice levels. It can be concluded that forming the balance between perceived action capacities and skills is critical for better designing and developing skill assessment surgical simulation tools.Article Attention mediates the effect of emotional arousal on learning outcomes in multimedia learning: an eye-tracking study(2023) Genc Aksaray, Sevgi; Özçelik, ErolRecent findings from psychological studies have shown that emotional arousal improves human memory. However, more evidence is necessary if these results are generalisable to multimedia learning environments. Considering these needs, the study has the goal to examine the effect of emotional arousal on multimedia learning. Fifty-seven participants were presented with instructional materials with either high- or low-arousing words and pictures in an experimental study. The eye movements of participants were recorded while they studied the instructional materials to examine the online processes during learning. The results suggest that emotional arousal enhanced recall and transfer scores. The eye-tracking results demonstrate that emotional arousal attracted attention. The results of the mediation analysis suggest that fixation time on emotional pictures as an indicator of attention mediated the relationship between emotional arousal and learning outcomes. The findings show the importance of the guidance of attention by emotional multimedia elements for learning.Book Part Citation - Scopus: 1Implications of Cognitive Theories for Optimizing Higher Education Learning(IGI Global, 2020) Ozcelik, E.Cognitive theories have the potential to provide suggestions to design more effective learning environments for higher education. The goal of this chapter is to review cognitive theories and principles based on empirical findings and suggest implications for practice. Working memory theory, distributed cognition theory, dual-process theory, modulatory emotional consolidation theory, mental model theory, metacognitive theory, transfer appropriate processing principle, generation effect, testing effect, and spacing effect are presented in the current study. Based on these theoretical frameworks, novel recommendations for educational practice are suggested. © 2021, IGI Global.

However, whilst the neural correlates of cognitive load are unclear, neuroimaging techniques such as functional magnetic resonance imaging (fMRI) may help provide answers to these questions. Aims: Considering this potential, this study aims to investigate which brain structures are associated with cognitive load through conducting an fMRI study on graph comprehension. Sample: The study's sample consists of 15 undergraduate students. Methods: Based on a within-subjects design, participants answered comprehension questions using split (i.e., high cognitive load) and integrated (i.e., low cognitive load) graphs whilst undergoing a magnetic resonance imaging (MRI) scan. Results: Participants exhibited lower levels of accuracy and slower reaction times with split graphs compared to integrated graphs. The fMRI data showed that cognitive load was associated with the frontoparietal network. More specifically, the multiple demand network revealed greater activation in graphs with higher cognitive load than those of lower cognitive load. Conclusions: These findings may indicate that a domain-general attentional brain network is responsible for cognitive load.Article Citation - WoS: 8Citation - Scopus: 7The Underlying Reasons of the Navigation Control Effect on Performance in a Virtual Reality Endoscopic Surgery Training Simulator(Taylor & Francis inc, 2019) Ozcelik, Erol; Berker, Mustafa; Dalveren, Gonca Gokce Menekse; Cagiltay, Nergiz ErcilNavigation control skills of surgeons become very critical for surgical procedures. Strategies improving these skills are important for developing higher-quality surgical training programs. In this study, the underlying reasons of the navigation control effect on performance in a virtual reality-based navigation environment are evaluated. The participants' performance is measured in conditions: navigation control display and paper-map display. Performance measures were collected from 45 beginners and experienced residents. The results suggest that navigation display significantly improved performance of the participants. Also, navigation was more beneficial for beginners than experienced participants. The underlying reason of the better performance in the navigation condition was due to lower number of looks to the map, which causes attention shifts between information sources. Accordingly, specific training scenarios and user interfaces can be developed to improve the navigation skills of the beginners considering some strategies to lower their number of references to the information sources.Article Citation - WoS: 4Citation - Scopus: 3The Effect of Integrative Prequestions on Learning From Text: an Eye-Tracking Study(Routledge Journals, Taylor & Francis Ltd, 2024) Bostan, Esra; Ozcelik, ErolAsking questions before studying (i.e., prequestions) is an effective strategy for learning, but there is not enough evidence demonstrating how integrative prequestions lead to a general benefit of learning. Considering this need, this study aimed to reveal the underlying cognitive processes contributing to this learning benefit using eye movement measurements. This study included 24 adults aged 18-35. Half of the participants were randomly selected to answer integrative questions before reading the passage (Prequestion Group). The other half did not receive prequestions before reading (Control Group). The results show that answering integrative questions before reading enhances the learning of both prequestioned and non-prequestioned sentences. Eye movement data demonstrates that the Prequestion Group exhibited increased attention, with a greater fixation number and longer complete fixation time on prequestioned sentences than the Control Group, and they also displayed more gaze transitions between these sentences during reading due to combining information related to prequestions. Interestingly, the Prequestion Group achieved higher post-test scores on non-prequestioned sentences, even though they paid less attention to these items than the Control Group. These findings suggest that integrative prequestioning can be used as an active learning strategy for students to foster deeper cognitive processes through the integration of information.Conference Object Guis With Haptic Interfaces(Springer Verlag, 2015) Ozcelik, E.; Tuner, E.; Sahin, H.; Tokdemir, G.; Arda Aydin, M.; Cagiltay, N.E.While there are many studies regarding utilization of Haptic feedback to enhance desktop GUIs and utilizing Haptic devices as additional interfaces to improve performance in current interaction techniques, there are not many studies that uses Haptic device as a primary input device. In this study, we present an experimentation conducted with 30 students, comparing performance of a Haptic device with mouse to use a GUI elements commonly used with mouse gestures. This study is inspired by a system that utilizes both mouse and a Haptic device, thus also taking task switching into consideration. We conclude that it is possible to achieve an acceptable performance with a Haptic device in a desktop-like GUI but further study and experimentation is necessary. © Springer International Publishing Switzerland 2015.Conference Object Citation - WoS: 6Citation - Scopus: 8Simulation-Based Environments for Surgical Practice(Ieee, 2017) Cagiltay, Nergiz Ercil; Ozcelik, Erol; Maras, Hakan; Dalveren, Gonca Gokce MenekseModeling and simulation environments provide several insights about the real situations such as endoscopic surgery. Endoscopic surgery requires both hand skills, so, understanding the effect of using dominant or non dominant hand on mental workload is important to better design, develop and implement modeling and simulation environments to support real-life implementations of surgical procedures. This experimental study presents a simulation application of eye-tracking approach to understand mental workload in different hand conditions: dominant hand, non-dominant hand and both hand. The results of the study show that, performing simulated surgical tasks by both hands compared to dominant hand, increases mental workload which is evident by higher pupil size. Accordingly, to manage the mental-load problems of surgeons while performing complex tasks that require both hand usage simulation-based environments can be used. Consequently, collection of detailed information such as eye-data, can give several insights about the behaviors of the surgeons. Also, their required skills can be improved by development of simulation and training environments.Article Anısal Bellekte Bilgilerin Kısa-süreli Konsolidasyonu: Dikkatin Rolü(2021) Ozcelik, Erol; Tekman, Hasan GürkanHızlı seri görsel sunum, dikkat kırpması, ve ikili görev bozulmaları olgularından elde edilen kanıtlar insanoğlunun kısa-süreli konsolidasyon sürecinde anlamlı bir sınırlılığı olduğunu öne sürmektedir. Kısa-süreli konsolidasyon, görsel temsillerin daha kalıcı bellek biçimlerine transfer edilmesidir. Yapılmış çalışmalar hedef uyaranlardan sonra gösterilen maskelerin bilgilerin konsolidasyonunu yarıda kestiğini göstermesine rağmen, bilgilerin anısal bellek için konsolidasyonunda dikkatin rolü hakkında yeterli kanıt yoktur. Dikkatin ve hedef uyaran ile maske arasındaki uyaran başlangıcı senkronizasyonsuzluğunun (UBS) anısal belleğe etkisini incelemek için üç deney yapılmıştır. Maskeler hedef uyaranlardan sonra değişen UBS'lerde sunulmuştur. Bölünmüş dikkat koşulundaki katılımcılar maskelerin sunumundan sonra dikkat gerektiren ikincil bir iş yaparken tam dikkat koşulundaki katılımcılara böyle bir görev verilmemiştir. Sonuçlar göstermiştir ki; hedef uyaranlar ile maskeler arasındaki UBS'yi düşürmek bölünmüş dikkatte bellek performansını düşürürken tam dikkatte performansı etkilememiştir. Bu bulgular kısa-süreli konsolidasyon sürecinde dikkatin gerekliliğini desteklemektedir.
