Article Citation - WoS: 11Citation - Scopus: 13Assessing Team Work in Engineering Projects(Tempus Publications, 2015) Mishra, Deepti; Ostrovska, Sofiya; Hacaloglu, Tuna; Mathematics; Computer Engineering; Information Systems EngineeringTeam work is considered a valuable teaching technique in higher education. However, the assessment of an individual's work in teams has proved to be a challenging task. Consequently, self-and peer-evaluations are becoming increasingly popular for the assessment of individuals in a team work, though it is essential to determine whether students can judge their own as well as their peer's performance effectively. Self-and peer-evaluations have been applied in different disciplines and their authenticity with regard to teacher's assessment has been evaluated in the literature but this issue has not been investigated in the field of engineering education so far. In this study, a peer-and self-assessment procedure is applied to the evaluation of a project work conducted in teams of 3 or 4 students. The participants were engineering students taking two similar courses related with database design and development. It is found that a majority of the students were unable to assess themselves as objectively as their instructor. Further, it is observed that successful students tend to under-estimate, whereas unsuccessful students tend to over-estimate, their own performance. The paper also establishes that the results of self-assessments are independent from the gender factor.Conference Object Citation - WoS: 3Citation - Scopus: 4Users' Behavioral Strategies Toward Mobile App Problems: Fight or Flight(Springer international Publishing Ag, 2019) Inal, Yavuz; Hacaloglu, TunaIn this paper, we identify two distinct behavioral strategies for dealing with problems encountered in the use of mobile apps - fight or flight. In the fight strategy, individuals do not give up using an app when faced with a problem; rather, they experiment with different ways to cope with that problem, whereas the flight strategy refers to the user's decision to uninstall an app when they encounter a problem and/or their intention to use an alternative app. These strategies were identified from an analysis of documents, which forty-two users reported, and can be used to understand how users deal with encountered problems. The participants were asked to use a mobile app of their choice for one week and report the behavioral strategies they utilized to counter problems they experienced. According to the findings obtained from content analysis, the most reported complaints concerned the categories of interface design, functional error, feature request, and feature removal. The participants who complained about functional errors, frustrating features, and slow application speed stopped using the app (flight behavior) whereas those that were dissatisfied with the interface, a missing feature or the content of the app continued to use the app and tried to overcome the problems (fight behavior).Article STUDY ON CLOUD COMPUTING PERCEPTION OF TURKISH IT SECTOR(Univ Osijek, Tech Fac, 2016) Okan, Aylin Akca; Hacaloglu, Tuna; Yazici, AliIn this paper an empirical study was carried out to study the Cloud Computing (CC) perception in Turkey. To this extent this study intends to determine the perception of Information Technology decision makers such as Chief Executive Officers and Chief Information Officers by means of a survey by questionnaire approach to explore 98 both public and private IT executives' understandings and concerns about CC. The survey aims to determine how CC is perceived by public or private organizations that are already involved in the e-transformation process. Major results of the study are as follows: both public and private sector executives have positive perception over adoption of CC, participants think that especially web, e-mail, data storage and process management applications are adequate for CC. Lack of well-educated and experienced staff is found to be the common barrier on adopting CC by both public and private sector participants.Conference Object Citation - WoS: 1Citation - Scopus: 3A Software Development Process Model for Cloud by Combining Traditional Approaches(Springer international Publishing Ag, 2015) Hacaloglu, Tuna; Eren, P. Erhan; Mishra, Deepti; Mishra, AlokEven though cloud computing is a technological paradigm that has been adopted more and more in various domains, there are few studies investigating the software development lifecycle in cloud computing applications and there is still not a comprehensive software development process model developed for cloud computing yet. Due to the nature of cloud computing that is completely different from the traditional software development, there is a need of suggesting process models to perform the software development systematically to create high quality software. In this study, we propose a new conceptual Software Development Life Cycle Model for Cloud Software Development that incorporates characteristics of different process models for traditional software development. The proposed model takes traditional model's specific characteristics into account and also considers cloud's specific nature i.e. advantages and challenges as well.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; Software Engineering; Information Systems EngineeringSoftware verification and validation (V & V) is one of the significant areas of software engineering for developing high quality software. It is also becoming part of the curriculum of a universities' software and computer engineering departments. This paper reports the experience of teaching undergraduate software engineering students and discusses the main problems encountered during the course, along with suggestions to overcome these problems. This study covers all the different topics generally covered in the software verification and validation course, including static verification and validation. It is found that prior knowledge about software quality concepts and good programming skills can help students to achieve success in this course. Further, team work can be chosen as a strategy, since it facilitates students' understanding and motivates them to study. It is observed that students were more successful in white box testing than in black box testing.
