    The effect of VR and traditional videos on learner retention and decision making
    (Birlesik Dunya Yenilik Arastirma ve Yayıncilik Merkezi, 2019) Yildirim, Gurkan; Yildirim, Serkan; Dolgunsoz, Emrah
    Virtual reality (VR) as computer-mediated 3-D environments including real-life situations presented via different tools in which users can interact effectively with visuals. This study is significant as it primarily aimed to investigate effects of VR on retention by comparing it with traditional 2-D videos. The main aim of this study is to compare the effect of VR and 2-D videos on learner retention and decision making. About 18 students from the Department of English language teaching in an age range of 18-20 (nine males and nine females) voluntarily participated in this study and took course credits. As all participants were tested under the same two conditions in different time periods; repeated measures were chosen for statistical analysis. It can be inferred that both technologies have similar effects on short-term retention and VR does not provide any extra retention performance. However, VR was found to have a significant effect on long-term retention. © 2019 SciencePark Research, Organization & Counseling. All rights reserved.

    Factors influencing e-books' continuance intention in the mobile environment
    (Inderscience Enterprises Ltd, 2021) Bolen, Mehmet Cem; Yildirim, Serkan; Yildirim, Gurkan
    The identification of factors that affect people's continuous use of e-books on their mobile devices is critical for e-book publishers, e-reader manufacturers and academic researchers. This study proposes a research model that extends the expectation-confirmation model by incorporating perceived enjoyment and facilitating conditions to get a deeper understanding of continuance intention to use e-books in the mobile environment. The structural equation model (SEM) was used to analyse data which were collected from 1,663 e-book readers by an online survey. The results indicate that satisfaction, perceived enjoyment, perceived usefulness and facilitating conditions influence continuance intention significantly. Furthermore, users' confirmation of expectations has a positive effect on perceived usefulness, perceived enjoyment and satisfaction. Surprisingly, perceived usefulness does not have a significant effect on satisfaction. Based on these findings, the theoretical and practical implications, limitations, and recommendations for future research are also discussed.

    Learners' views about cloud computing-based group activities
    (E D P Sciences, 2017) Yildirim, Serkan; Bolen, Mehmet Cem; Yildirim, Gurkan
    Thanks to its use independently of time and place during the process of software development and by making it easier to access to information with mobile technologies, cloud based environments attracted the attention of education world and this technology started to be used in various activities. In this study, for programming education, the effects of extracurricular group assignments in cloud based environments on learners were evaluated in terms of group work satisfaction, ease of use and user satisfaction. Within the scope of computer programming education lasting eight weeks, a total of 100 students participated in the study including 34 men and 66 women. Participants were divided into groups of at least three people considering the advantages of cooperative learning in programming education. In this study carried out in both conventional and cloud based environments, between groups factorial design was used as research design. The data collected by questionnaires of opinions of group work were examined with quantitative analysis method. According to the study results extracurricular learning activities as group activity created satisfaction. However, perceptions of easy use of the environment and user satisfaction were partly positive. Despite the similar understandings; male participants were easier to perceive use of cloud computing based environments. Some variables such as class level, satisfaction, computer and internet usage time do not have any effect on satisfaction and perceptions of ease of use. Evening class students stated that they found it easy to use cloud based learning environments and became more satisfied with using these environments besides being happier with group work than daytime students.

    A study on the development of an infographic designer questionnaire and designer opinions
    (E D P Sciences, 2016) Yildirim, Serkan; Yildirim, Gurkan; Celik, Embiya; Kaban, Abdullatif
    Technological developments and changes in how learning is understood have not only changed learning environments, but also how educational materials are developed. Infographics, one of the materials that are becoming increasingly more popular in learning environments, have nowadays become quite commonplace. Demonstrating the understanding of those who design such instructional materials is important with respect to the organisation of learning processes. In this study, we devised a questionnaire that aims to demonstrate the understanding infographic designers have of infographic design. A total of 94 students from the Department of Computer and Instructional Technologies Education of the Kazim Karabekir Faculty of Education took part in this study conducted during the fall semester of the 2013-2014 academic year. The participants were given a questionnaire consisting of 41 items that enquired about the readers' views regarding infographic design. The collected data were assessed using Principal Component Analysis. Based on the analysis results, a questionnaire form consisting of 27 items and 8 factors (Understanding of Design, Design Process, Copyrights, Introduction, Readability, Sharing, References, Development) was developed.

    A study on the development of an infographic reader questionnaire and reader opinions
    (E D P Sciences, 2016) Yildirim, Serkan; Celik, Embiya; Yildirim, Gurkan; Kaban, Abdullatif
    Educational materials are commonly used to assist with communication during learning. One of the ways to determine the use of educational materials and their contribution to the learning process is to ask students for their opinions. Student opinions provide useful information regarding various objectives such as making both the learning process and resources more effective, bringing about the necessary improvements and organising the teaching process. In this study, we developed a questionnaire for determining the opinions of information graphics (infographics) readers on information graphics prepared for teaching purposes. This study was conducted in the fall semester of the 2013-2014 academic year with the participation of 59 students from the Department of Computer and Instructional Technologies Education of the Kazim Karabekir Faculty of Education. The students were provided with a questionnaire consisting of 29 items that inquired their opinions on infographics. The collected data were assessed using Principal Component Analysis. Based on the analysis results, a second questionnaire consisting of 23 items and six factors (Learnability, Selection Preferences, Sharing, Basic Presentation Structure, Memorability, and Role in the Learning Process) was developed. According to the study results, the students considered infographics as highly instructive, and described that they help ensure a more lasting learning experience.
