Article Citation - WoS: 6Citation - Scopus: 10Comparison of the Discussion Sections of Phd Dissertations in Educational Technology: the Case of Turkey and the Usa(Springer, 2018) Karsli, Meva Bayrak; Karabey, Sinem; Cagiltay, Nergiz Ercil; Goktas, Yuksel; Software EngineeringIn academic studies, the discussion section is important in which the effect of the results of the study on the existing literature is highlighted and interpreted. The aim of the current paper is to compare the discussion sections of Turkish and American PhD dissertations in the field of Educational Technologies, taking into consideration the basic features that should be found in an effective discussion section. For this purpose, a content analysis was carried out using a checklist developed to examine the basic components, the presentation of the results, the interpretation of the results, and the overall language of 120 PhD dissertations published in this field. The study showed although there were strong aspects, the contribution to the literature and limitations of studies were only included in some of the Turkish PhD dissertations; however, they were included in the majority of American PhD dissertations. Almost all of the dissertations explained the findings and their significance; however, there was no emphasis on the significant and interesting findings in Turkish PhD dissertations. The number of pages of the discussion section in Turkish and American PhD dissertations was almost the same, and the relationship between the number of pages of the discussion section and the quality of the discussion section was rather weak in the dissertations from both countries. The results obtained from the study were evaluated in general and suggestions to consider when writing the discussion section are given.Article Citation - WoS: 63Citation - Scopus: 85Mapping Human-Computer Interaction Research Themes and Trends From Its Existence To Today: a Topic Modeling-Based Review of Past 60 Years(Taylor & Francis inc, 2021) Gurcan, Fatih; Cagiltay, Nergiz Ercil; Cagiltay, Kursat; Software EngineeringAs it covers a wide spectrum, the research literature of human-computer interaction (HCI) studies has a rich and multi-disciplinary content where there are limited studies demonstrating the big picture of the field. Such an analysis provides researchers with a better understanding of the field, revealing current issues, challenges, and potential research gaps. This study aims to explore the research trends in the developmental stages of the HCI studies over the past 60 years. Automated text mining with probabilistic topic modeling has been used to analyze 41,720 journal articles that are indexed by the SCOPUS database between 1957 and 2018. The results of this study reveal 21 major topics mapping the research landscape of HCI. By extending the discovered topics beyond a snapshot, the topics were analyzed considering their developmental stages, volume, and accelerations to provide a panoramic view that shows the increase and decrease of trends over time. In this context, the transition of HCI studies from machine-oriented systems to human-oriented systems indicates its future direction toward context-aware adaptive systems.Article Design and Development of a Remote and Virtual Environment for Experimental Training in Electrical and Electronics Engineering(2010 9th International Conference on Information Technology Based Higher Education and Training (ITHET), 2010) Kara, Ali; Aydın, Elif; Özbek, Mehme Efe; Çağıltay, Nergiz; Department of Electrical & Electronics Engineering; Software EngineeringEuropean Remote Radio Laboratory (ERRL) has been developed by the support of European Commission. It intends to provide remote access to high cost devices remotely, and perform experiments in radio frequency (RF), communications and microwave domains of Electrical and Electronics Engineering. The system has been operational for two years, and been integrated into curriculum of some courses. In this work, the hardware and software structures of the system are presented. Then, experimental content and the motivations in the design of the system are discussed.Article Teaching Usage of Equipments in a Remote Laboratory(2008) Alparslan, Nimet Ceren; Çağıltay, Nergiz; Özen, Mustafa; Aydın, Elif; Department of Electrical & Electronics Engineering; Software EngineeringRemote laboratories are technologies that aim to increase the effectiveness of educational programs. European Remote Radio Laboratory (ERRL) is an e-learning project for students, teachers and technicians who will use very important devices of a radio frequency laboratory remotely. As a solution we have developed an e-learning system which aims to support the ERRL learners while studying on how to use equipments in the system. The system is developed according to the electronic performance support system (EPSS) approach. An EPSS is a computer-based, well-structured system which improves the performance of individuals. It is an electronic infrastructure that contains, stores and distributes personal (individual) or corporate knowledge to enable people to reach necessary levels of performance in the fastest possible time and with minimum teaching support of other people. This paper discusses how the content for such a system is developed and how this content is interactively used in the EPSS platform. The technical details of the developed EPSS are also discussed in this study. We believe that this paper will help instructional system designers for designing different alternatives to improve learners’ performance.Conference Object Citation - WoS: 0Developing a Data Warehouse for Distance Remote Laboratory(Ieee, 2007) Turkmen, Guzin; Cagiltay, Nergiz Ercil; Computer Engineering; Software EngineeringData warehouse is an important contemporary issue for many organizations and is relatively a new field in the realm of information technology. As data warehousing, e-learning is also a new field. little research has been done regarding the special considerations and characteristics of academic data and the complexity of analyzing such data. Educational institutions measure success very differently from business-oriented organizations and the analyses that are meaningful in such environments cause unique problems in data warehousing. Especially for the educational purposes, data warehouses offer several benefits. This paper discusses the use of Data Warehouse and Decision Support resources to aid in die assessment of Distance Remote Laboratory Environment.Conference Object Citation - WoS: 0A remote laboratory for training in radio communications(Ieee, 2007) Kara, Ali; Aydin, Elif Uray; Oektem, Rusen; Cagiltay, Nergiz; Department of Electrical & Electronics Engineering; Software EngineeringThis paper presents, first, a short survey of remote laboratory initiatives in electrical and computer engineering, and then discusses design and development phases of remote laboratory environment on radio communications, the ERRL (European Remote Radio Laboratory).

Endoscopic surgeries have become an alternative for open procedures whenever possible. For such types of operations, surgeons are required to gain several skills, whose development needs hands-on practice. Accordingly, gaining these skills today is a challenge for surgical education programs. Despite the development of several technology-enhanced training environments, there are still problems to better integrate these technologies into educational programs. For an appropriate integration, it is critical to assess the skill levels and adapt the training content according to the trainees' requirements. In the literature, there exist several methods for assessing these skill levels. However, there are still problems in practice for objective and repetitive assessment. Methods. The present study aims to estimate the skill levels of participants in surgical training programs in an objective manner by collecting experimental data from residents in an endoscopic surgical simulation environment and gathering performance metrics. Results. It is shown that, by comparing the results of a number of classification algorithms for the best accuracy estimation and feature set, the "novice" and "intermediate" skill levels can be estimated with an accuracy of 86%. Conclusions. The outcomes help surgical educators and instructional system designers to better assess the skill levels of the trainees and guide them accordingly. In addition, objective assessments as highlighted in this study can be beneficial when designing technology-enhanced adaptive learning environments.Article How Content Management Problem of a Remote Laboratory System Can Be Handled by Integrating an Open Source Learning Management System? Problems and Solutions(IEEE, 2007) Çağıltay, Nergiz; Özdoğru, Burcu; Software EngineeringThis paper represents the design and implementation of the integration process of an open source learning management system (LMS) to the remote laboratory platform. The reason of using a learning management system is to prevent the problems which can be seen in the learner side of the remote laboratory systems. However, since using a learning management system such as Moodle can handle the learner problems, since it is a separate system, there are still other problems to be handled such as integrating it with the other parts of remote laboratory systems. This study explores the background information of LMS, the problems faced while integrating Moodle to remote laboratory applications, the chosen content management systems’ architecture, our architecture for integrating Moodle with the remote laboratory system and the solutions we propose for the problems.Article Citation - WoS: 6Citation - Scopus: 7Teaching Software Verification and Validation Course: a Case Study(Tempus Publications, 2014) Mishra, Deepti; Hacaloglu, Tuna; Mishra, Alok; Computer Engineering; Computer Engineering; Software Engineering; Information Systems Engineering; Software Engineering; Information Systems EngineeringSoftware verification and validation (V & V) is one of the significant areas of software engineering for developing high quality software.
