Öğe DEVELOPMENT OF USABILITY CRITERIA FOR E-LEARNING CONTENT DEVELOPMENT SOFTWARE(Anadolu Univ, 2012) Celik, SerkanRevolutionary advancements have been observed in e-learning technologies though an amalgamated evaluation methodology for new generation e-learning content development tools is not available. The evaluation of educational software for online use must consider its usability and as well as its pedagogic effectiveness. This study is a first step towards the definition of criteria for evaluating e-learning tools. A preliminary user study involving a group of pre-service instructional designers, observed during their interaction with e-learning tools, is reported. Throughout the study, specific usability attributes of these e-learning tools were identified. Participants were assigned to rate the importance of functional and pedagogical competences proposed during the criteria development phase. The findings of the study revealed 31 evaluation criteria under the headings of technical, media, and assessment competences. Among the groups of benchmarks proposed and rated by the users, assessment was considered as the most important one while technical and media features were even. The following step was actual implemention of the usability criteria into evaluation of fifteen leading software used in e-learning across the world. Mostly, tools were observed as having limitations in terms of capabilities. Comparing to the other software, Captivate, Softchalk, and Lectora were regarded as outstanding tools by the participants. Following the discussion on the limitations of the study, some implications for further research were proposed.Öğe The Effect of Data-Driven Learning Approach on EFL Learners' Lexical Acquisition(Turkish Education Assoc, 2010) Celik, Serkan; Keser, HafizeThis semi-experimental research was conducted to investigate the effects of data-driven learning (DDL) on learners' achievement and retention of lexical acquisition. Instruction was delivered through a learning management system. The data collection instrument, of which reliability and validity were tested, is a vocabulary knowledge scale. The statistical method used to analyze the data besides the descriptives was Ancova. The results of the study revealed that the learners utilized the data-driven learning tools performed a significant achievement and retention on acquisition of academic words comparing to the control group.Öğe The Effect of Personality on Cyberbullying among University Students in Turkey(Ani Yayincilik, 2012) Celik, Serkan; Atak, Hasan; Erguzen, AtillaProblem Statement: Cyberbullying is associated with significant psychological issues among young people such as depression, emotional distress, low self-esteem, and poor academic achievement. It is also regarded as an increasingly emergent problem in educational settings, putting learners' psychological health, safety, and well-being at risk. Recent research has shown that a growing number of students are victims of cyberbullying and a wider realization and a thorough understanding of cyberbullying is needed. Purpose of the Study: This survey-based study set out to explore the relationship between personality traits and cyberbullying among university students receiving education through either face-to-face or distance education modes. Methods: A sectional research design and correlation survey method was adopted throughout the study. As a causal and comparative study, the dependent variable was set as cyberbullying (actively bullying others and/or being bullied) and the independent variable included five personality types. A path model was developed and tested in order to investigate the effects of learning modes and aforementioned personality types on two levels of cyberbullying. Findings and Results: The good fit indexes belonging to the model indicated acceptable conditions and capacity for explaining the relations among the variables. Emotional instability was observed as the leading predictor of being cyberbullied with a medium effect size. On the other hand, the weakest predictor of being bullied was found to be openness to experience with a minor level negative effect size. The developed model was observed to be valid for both face-to-face and distance education learning modes. In addition, a positive and medium level relationship between bullying and being exposed to bullying was observed. Ward's hierarchical cluster analysis conducted on the points obtained from the cyberbullying scale revealed that the majority of the group rarely bullies and is rarely exposed to cyberbullying. Conclusions and Recommendations: This study contributes to the extant literature on bullying in a few conceptual areas. For instance, few research studies have examined the bullying issue in the tertiary context and through learning modes. The current investigation was limited by using a single data set to conduct all analyses. Further research is recommended to involve various variables such as cross-cultural effects on cyberbullying.Öğe Improving 8 th grades spatial thinking abilities through A 3D modeling program(Turkish Online Journal Educational Tech-Tojet, 2012) Toptas, Veli; Celik, Serkan; Karaca, E. TugceImplementation of emerging technology in sub disciplines of mathematics education provides a potential for educators to elaborate the capacity of digitized learning for human being. Spatial thinking is considered as a factor of scientific deduction from a multi disciplinary point of view. This paper reports a study aimed at exploring the effect of a 3D Modeling program on the spatial ability of the 8th grade students through an experimental research design. The study also focuses on the relation between the gender difference and spatial thinking. The study population was consisted of 82 8th grade students and divided into the control group (n=40) and the treatment group (n=42). The data in the study were collected through a qualitative research method. According to the findings of the research, the success rate of post test increased after the application in terms of differential aptitude, mental rotation and spatial visualization. On the other hand, irrespective of the relevant literature, female pupils were observed as better performers comparing to the males on post application of the measurement instruments.Öğe Internet-assisted technologies for English language teaching in Turkish universities(Routledge Journals, Taylor & Francis Ltd, 2013) Celik, SerkanAlthough the enormous potential of the Internet has gained attention in Internet-assisted language teaching (IALT), a solid background of research is still lacking about/investigating English as a foreign language (EFL) teachers' use of Internet assistive technologies. This study set out to determine Turkish university level EFL instructors' perceptions and perspectives on the use of the Internet for pedagogical purposes. A total of 486 instructors from 11 universities located in Turkey participated in a survey and responded to the questions about what type of resources they utilize on the Internet, how they perceive and use Internet-assisted language instruction, and how they assess themselves in terms of language learning technology. The findings reveal that although EFL instructors utilize the Internet densely and with a positive perception in their teaching, the quality of that utilization varies and needs to be improved via professional development programs for Internet-assisted language instruction. Suggestions were made for further research.Öğe iTunes University: Potentials and Applications(Elsevier Science Bv, 2012) Celik, Serkan; Toptas, Veli; Karaca, TugceThis paper aims to introduce iTunes University as a service that can be used to design and distribute courses that supplement traditional print media. Besides, it purports the pros and cons of the iTunes university service such as modernizing the metarials, easy access and organization, free courses and positive marketing, and expense, training, losing control, and investment respectively. The paper also focuses on the educational opportunities attached with the iTunesU application and its connection with other apple technology and discusses how the platform can be used to create interactive learning material for students at various educational levels.

The purpose of this research was to perform a comparison of online and face-to-face delivery modes for an introductory first aid course to determine if there existed a difference in student teachers' success depending on the delivery modes. Methods: The research compares participants' achievements in a first aid class taught by the same instructor using either face-to-face or online delivery modes. In total, five sections of the course were assigned to either a face-to face or an online treatment condition. Results: The results of a paired samples t-test indicated that student teachers both in experiment and control groups performed adequately to attain the course goals (p < .05). The difference between the mean scores of all groups in pre- and post-tests verified the achievement of the participant learners. The results of a further independent t-test on groups' performances on the post application of the achievement test showed a significant variance in favour of participants who received online teaching (p < .05). Conclusion: The findings of the study suggest that, while both online and face-to-face mode can be effective in achieving learning goals of first aid content, online learning was found to be more effective in comparison to traditional classroom instruction.Öğe PREDICTIVE ROLE OF PERSONALITY TRAITS ON INTERNET ADDICTION(Anadolu Univ, 2012) Celik, Serkan; Atak, Hasan; Basal, AhmetAiming to develop a model seeking to investigate the direct effects of personality types on internet addiction, this study was set and tested on tertiary level students receiving education within two learning modes: face to face and distance education. The participants of the study, selected through maximum variety method within purposive sampling, included 210 students enrolled on face-to-face and distance education programs of computer programming department. In addition to a personal data form aiming to obtain information on demographic features of the participants, a personality inventory and an Internet addiction scale were utilized to gather data. As an analysis model concurrently exerting both the mediation and direct effects, path analysis with observed variables was utilized in the current study to test the developed model. The findings revealed that while the most powerful predictor variable of internet addiction was conscientiousness, openness to experience was found as the weakest independent variable predictor. Additionally the developed model was observed as valid for both face to face and distance education students.Öğe Vocabulary learning strategy use of Turkish EFL learners(Elsevier Science Bv, 2010) Celik, Serkan; Toptas, VeliThis survey study aimed to examine vocabulary-learning strategies adopted by Turkish EFL students, specifically the frequencies and helpfulness ratings of strategy use, strategy patterns, as well as their change for students across different language levels. The study involved 95 tertiary level English as a foreign language learners. Data were analyzed statistically and the results indicated that the participants' general use of vocabulary learning strategies was somewhat inadequate and there was a gap between their use of strategies and related perceptions of strategy usefulness.
