Article How Can We Get Benefits of Computer-Based Testing in Engineering Education?(Computer Applications in Engineering Education, 2010) Çağıltay, Nergiz; Özalp Yaman, ŞenizUsing computers for assessment can provide several benefits for educators and test-takers. However, in the literature, there is no consensus on the equivalence of paper-and-pencil (P&P) and computer-based test (CBT) environments. Additionally, these studies fail to address the engineering domain. Our main assumption is that, if we could define the confounding factors to satisfy that these two versions of the tests provide equivalent results, then especially in the first year courses of the engineering education programs, we could get several benefits of the CBT environments. Accordingly, in this study, students' performance o different test modes waws evaluated on 209 first year engineering students of a chemistry course. The results of this study showed that there is no significant performance difference between P&P and CBT. By comparing results with the previous studies, this study concludes that personal characteristics of test talers, the features of CBT systems, and the test content are all possible confounding factors when comparing test modes anf need to be considered by the implementers. The results of this study show that once these factors are controlled, students' performance on CBTs and P&P tests in chemistry courses will not vary. This finding is encourging the educators to get benefits of CBTs without any affect on students' performance.Article Requirements for Remote Rf Laboratory Applications: an Educators’ Perspective(IEEE TRANSACTIONS ON EDUCATION, 2009) Çağıltay, Nergiz; Aydın, Elif; Öktem, Ruşen; Kara, Ali; Alexandru, Marian; Reıner, BodoThis paper discusses the results of a study of the requirements for developing a remote RF laboratory. This study draws on the perspectives of educators in university electrical engineering departments and in technical colleges, on the teaching of the radio frequency (RF) domain. The study investigates how these educators would like the technical content of a state of the art RF laboratory to be designed. As far as the authors know, no publication exists in the literature that investigates the requirements and needs of remote laboratories in that particular field. The outcomes of this work are expected to guide remote laboratory platform developers towards the most effective design of their platforms. The analysis of the results showed that educators would like the technical content of the laboratory to cover basic communication techniques, microwave circuits and devices, antennas and propagation, RF technology, and radio system design aspects of modern telecommunication systems. They would therefore like the laboratory instrumentation to be designed to that end. The educators also reported the need for advanced experimental setups which require expensive RF measurement devices. The discrepancy between university and technical college views was also considered in this paper.Article Use of Advanced Technologies in a Rf and Microwave Engineering Course(IEEE, 2010) Aydın, Elif; Çağıltay, NergizIn RF and Microwave Engineering course, usually students struggle to build connections between the theory they have learned and practical applications in the laboratory. The laboratory applications are usually very limited for hands on experience since the high cost and maintenance requirements of the equipment. Additionally, new engineers need to know how to use at least one engineering design tool in order to practice designing RF components, circuits, or antennas. In this study, a curriculum model including recent developments and technologies in the RF and Microwave Engineering field by addressing above problems of the course 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 which covers the use of a remote laboratory environment, Concept Maps and an engineering design tool. The course is structured with a balance between theory and laboratory, including remote and in lab measurement experiments as well as modeling and designing microwave components by means of computer tools and design fabrication. The newly designed course is implemented at the Atilim University. The first semester implementation shows promising results.Article BİR ELEKTRONİK KÜTÜPHANE PROJESİNE BAŞLARKEN(2001) Çağıltay, NergizBu çalışmanın temel amacı, İndiana Üniversitesi elektronik (sayılsal) kütüphane programında halen yürütülmekta olan çalışmalrı incelemektir.

The manual solution of this problem by considering all constraints usually requires a long time and a hard work in order to provide an appropriate solution. In addition, the obtained solution usually is unsatisfactory due to limited human oversight. In this study, Genetic Algorithm (GA) is presented for solving the constraint-based university timetabling problem. The developed system includes flexible and intelligent software that automate the course scheduling task and addresses all special features found in Atilim University’s Engineering Faculty.Article Paper-Based Versus Computer-Based Testing in Engineering Education(IEEE EDUCON Education Engineering 2010 – The Future of Global Learning Engineering Education, 2010) Çağıltay, Nergiz; Özalp Yaman, ŞenizUsing computers for assessment can provide several benefits for educators and test-takers. However, in the literature, there is no consensus on the equivalence of paper-and-pencil and computer-based test environments. Accordingly, more evidences are needed especially for the engineering education. In this study, students’ performance on different test modes was evaluated on 209 first year engineering students of a chemistry course. The results of this study showed that, there is no significant performance difference between paper-and-pencil and computer based tests. By comparing results with the previous studies, this study concludes that, personal characteristics of test takers, the features of computer-based testing systems and the test content are all possible confounding factors when comparing test modes and need to be considered by the implementers. The results of this study show that, once these factors are controlled, students’ performance on computer-based tests and paper-and-pencil tests in chemistry courses for the engineering students will not vary. This finding is encouraging the educators to get benefits of computer-based tests without any affect on students’ performance.Article Remote Laboratory Development as an Action Research: a Case Study(2012) Çağıltay, Nergiz; Tokdemir, Gül; Aydın, Elif; Kara, AliThis work presents a case study about how action research (AR) has been conducted in developing a real-life educational system.
