Article How To Teach Usage of Equipments in a Remote Laboratory(IEEE, 2007) Alparslan, Nimet Ceren; Çağıltay, Nergiz; Özen, Mustafa; Aydın, ElifEuropean Remote Radio Laboratory (ERRL) is an e learning project for students, teachers and technicians of the universities who will use the very important devices of this laboratory remotely. These devices are very expensive to buy and can be broken easily while they have been using by the people who does not really know how to use them professionally. 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 systems (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.Article A Mobile Application Flow Representation for Mutual Understanding of It and Healthcare Professionals(2013) Erturan, Yusuf Nasuh; Bilgen, Semih; Tokdemir, Gül; Çağıltay, Nergiz; Yıldız, Ekrem; Özcebe, EsraEver since mobile applications were developed and became popular, they have started to take part in almost every field of our lives. Healthcare is one of the most popular fields that mobile applications have become a part of. However, development of mobile healthcare applications requires an inter disciplinary work on which people from different domains should communi cate. To do so efficiently, mobile application instructions should be provided as clearly as possible so that mutual understanding can be achieved. This study, aims to provide a methodology to provide the common grounds for healthcare and IT specialists so that to improve the satisfaction level of all the stakeholders of the system from the provided IT services and the end-user interfaces. In other words, by providing a better communication medium for the stakeholders dur ing the design phase, we believe that software development process will be improved, so do their satisfaction from the developed system.Article MEDİKAL EĞİTİMDE ÖĞRETİM TEKNOLOJİLERİNİN ROLÜ VE ÖNEMİ(2015) Çağıltay, NergizGünümüzde medikal eğitim süreçleri, son derece zahmetli ve uzun bir eğitim programını içermektedir. Teknolojide yaşanan baş döndüren ilerlemelere rağmen ülkemizde ve dünyada medikal eğitim alanında ciddi gelişmeler elde edilememekte ve yoğunlukla İngilizce “one see-one do-one teach” olarak nitelendirilen ülkemizde ise usta-çırak yaklaşımı olarak bilinen yöntem ile bu eğitimler gerçekleştirilmektedir. Ancak, özellikle çeşitli beceri yeteneklerinin geliştirilmesinin önemli olduğu medikal eğitim programlarında uygulamaya ve deneme yanılmaya yönelik olarak sunulması gereken içeriklerde önemli sıkıntılar yaşanmaktadır. Alanyazında yapılan çalışmalar, yaparak öğrenme, hata yapma ve hatalarından öğrenme, deneme yanılma yolu ile öğrenme gibi yaklaşımların öğrenme süreçlerine olan katkısını ve önemini vurgulamaktadır. Ancak, medikal eğitim süreçleri değerlendirildiğinde bu tür olanakların sağlandığı eğitim-öğretim programlarının hazırlanması aşamasında ciddi problemlerle karşılaşılmakta ve bu süreç çok da kolay olamamaktadır. Gerçek ortamlarda hasta başında bu tür deneyimlerin sunulması, gerek hasta sağlığı açısından, gerek etik kurallar açısından, gerekse hata kaldırmayan bir ortam olması nedeniyle çok mümkün olamamaktadır. Bu sorunları aşabilmek amacıyla, medikal eğitim süreçlerinde deneyime yönelik yeteneklerin kazandırılması amacıyla özel bazı modeller ve düzenekler hazırlanarak öğrencilere bu yeteneklerin kazandırılmaya çalışılması ya da kadavra eğitimlerinin verilmesi ile öğrencilerin deneyimlerinin artırılması sağlanmaktadır. Ancak bu tür düzeneklerin kurulması son derece zahmetli olmakta, tekrarlı bir şekilde bu eğitimlerin sunulmasının sağlanması amacıyla her eğitim seansının sonunda bu düzeneklerin yeniden kurulması gerekmekte ve belli bir kullanım süreci sonunda düzeneklerin tamamen yenilenmesi gerekmektedir. Kadavra eğitimlerinde de benzer sorunlar yaşanmakta, bu tür eğitim programlarını hazırlayan eğitimcilerin özellikle ülkemizde kadavra bulmakta önemli sıkıntılar yaşadıkları ve bu konudaki maliyetlerin son derece önemli boyutlarda olduğu bilinmektedir.Article How Assessment System of an Open Source Learning Management System Can Be Integrated To a Remote Laboratory Application? Problems and Solutions(IEEE, 2007) Aydın, Cansu Çiğdem; Çağıltay, NergizMost of the education programs need an assessment system for formative and summative evaluation purposes. Similarly, in the ERRL* project which is a distance remote radio frequency laboratory application, assessment system is required. However, developing an assessment system cost is very high and requires some extra time for testing and development purposes. Open source systems provide these services in a standard way. Since the source is open, it is possible to make some modifications to better adapt these systems to the requirements of developed systems. Similarly, in the Moodle part of the system we need to integrate the test and the experiment platforms. In order to better guide the learners in the system, they should take some tests about the devices and the theoretical content included in the system. It is important to prevent users who do not have the enough knowledge directed to the experiments platform. These testing requirements should be integrated into the remote laboratory system, so that, the learners should not need to jump between different systems and interfaces. This article presents implementation process of open source Learning Management System software’s assessment module to a remote laboratory application and it also discusses the advantages, disadvantages of using an open source Web based assessment system.Article A New Rf and Microwave Engineering Course Enriched With Advanced Technologies(2010) Aydın, Elif; Çağıltay, NergizIn this study, a curriculum model including recent developments and technologies in the Radio Frequency (RF) and Microwave Engineering field by using a blended approach is proposed. This study covers the description of the content of theoretical and hands on applications, the integration model of the technological tools into the proposed curriculum, and the instructional approaches used in the new course design. The main goal of the course is to prepare students for future professional careers in RF and Microwave Engineering by supporting them with new instructional technologies.

Problems and Solutions(IEEE, 2007) Çağıltay, Nergiz; Özdoğru, BurcuThis 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 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, NergizEuropean Remote Radio Laboratory (ERRL) has been developed by the support of European Commission.
