Item The Effects of Teaching Programming via Scratch on Problem Solving Skills: A Discussion from Learners' Perspective(2014) Kalelioglu, Filiz; Gulbahar, Yasemin; 0000-0002-7729-5674; AAF-8110-2019Computer programming is perceived as an important competence for the development of problem solving skills in addition to logical reasoning. Hence, its integration throughout all educational levels, as well as the early ages, is considered valuable and research studies are carried out to explore the phenomenon in more detail. In light of these facts, this study is an exploratory effort to investigate the effect of Scratch programming on 5th grade primary school students' problem solving skills. Moreover, the researchers wondered what 5th grade primary school students think about programming. This study was carried out in an explanatory sequential mixed methods design with the participation of 49 primary school students. According to the quantitative results, programming in Scratch platform did not cause any significant differences in the problem solving skills of the primary school students. There is only a non-significant increase in the mean of the factor of "self-confidence in their problem solving ability". When the thoughts of the primary students were considered, it can be clearly stated that all the students liked programming and wanted to improve their programming. Finally, most of the students found the Scratch platform easy to use.Item A New Way of Teaching Programming Skills to K-12 Students: Code.org(2015) Kalelioglu, Filiz; 0000-0002-7729-5674; AAF-8110-2019This study attempts to investigate the effect of teaching code.org site on reflective thinking skills towards problem solving. More specifically, this study attempts to investigate whether there is a gender difference in terms of students' reflective thinking skills towards problem solving. This triangulation study was conducted with 32 primary school students. The quantitative part of the study was conducted in pre-test/post-test comparison design of quasi-experimental design. The scores of reflective problem solving skills were gathered through the reflective thinking skill scale towards problem solving and the students' performances in the code-org site were examined. In the qualitative part of the research, after the five-week experimental process, focus group interviews were conducted with ten students and a reflection paper from the IT teacher was analysed. According to the t-test results, teaching programming to primary school students in the code.org site did not cause any differences in reflective thinking skills towards problem solving. However, there is a slight increment in the means of female students' reflective thinking skills towards problem solving over the males' reflective thinking skills towards problem solving. On the other hand, qualitative data provided more information about the students' experiences. Students developed a positive attitude towards programming, and female students showed that they were as successful as their male counterparts, and that programming could be part of their future plans.

Today, to the contrary, people of most ages are expected to possess basic computing skills in parallel with the requirements of up-to-date technological tools. To equip students with the necessary skills, computer science courses need to be delivered compulsorily, or at least delivered as a part of another course for almost all age groups and levels. Besides delivering these courses, awareness of this valuable skill is also essential, and for this aim, Olympiads or contests are now held in many countries. Bebras International Contest is one such organisation. In December 2014, Turkey also participated in this contest with 1,788 elementary students from different cities. This paper examines the student performance of the 2014 Bilge Kunduz (the Turkish term for Bebras) International Informatics Contest and explores coordinators' perceptions about the contest. Based on the student performance and overall success, the average score in Turkey was 65.01 (where scores varied between 0 and 135). According to the perceptions of coordinators, it can be said that the contest was favoured by all coordinators, but that some enhancements to the contest platform are needed.Item Bilgisayar Okuryazarlığı(2017) Cabı, Emine; Ersoy, Halil; Kalelioglu, Filiz; Avcı, Ümmühan; Koç, Serdar Engin; Çetinkaya, Hüseyin HakanItem The Effect of Instructional Techniques on Critical Thinking and Critical Thinking Dispositions in Online Discussion(2014) Kalelioglu, Filiz; Gulbahar, YaseminThe aim of this research study was to explore the effect of instructional techniques on critical thinking and critical thinking dispositions in online discussion, based on triangulation design. Six Thinking Hats, Brainstorming, Role Playing, Socratic Seminar, and Anyone Here an Expert, were selected as an instructional techniques for online discussion. In the quantitative part, according to the results of ANOVA, except Socratic Seminar, there is no difference between groups in terms of scores of pre-tests and post-tests of critical thinking dispositions. In the qualitative part, according to the results of the analysis of critical thinking in online discussion, the Mixed Techniques group performed as having the best ability of critical thinking, the Anyone Here an Expert group was second and the Brainstorming group was third in terms of performing critical thinking ability in online discussion.Item A Framework for Computational Thinking Based on a Systematic Research Review(2016) Kalelioglu, Filiz; Gulbahar, Yasemin; Kukul, VolkanComputational Thinking (CT) has become popular in recent years and has been recognised as an essential skill for all, as members of the digital age. Many researchers have tried to define CT and have conducted studies about this topic. However, CT literature is at an early stage of maturity, and is far from either explaining what CT is, or how to teach and assess this skill. In the light of this state of affairs, the purpose of this study is to examine the purpose, target population, theoretical basis, definition, scope, type and employed research design of selected papers in the literature that have focused on computational thinking, and to provide a framework about the notion, scope and elements of CT. In order to reveal the literature and create the framework for computational thinking, an inductive qualitative content analysis was conducted on 125 papers about CT, selected according to pre-defined criteria from six different databases and digital libraries. According to the results, the main topics covered in the papers composed of activities (computerised or unplugged) that promote CT in the curriculum. The targeted population of the papers was mainly K-12. Gamed-based learning and constructivism were the main theories covered as the basis for CT papers. Most of the papers were written for academic conferences and mainly composed of personal views about CT. The study also identified the most commonly used words in the definitions and scope of CT, which in turn formed the framework of CT. The findings obtained in this study may not only be useful in the exploration of research topics in CT and the identification of CT in the literature, but also support those who need guidance for developing tasks or programs about computational thinking and informatics.Item ASSESSMENT OF A MULTINATIONAL ONLINE FACULTY DEVELOPMENT PROGRAM ON ONLINE TEACHING: REFLECTIONS OF CANDIDATE E-TUTORS(2017) Kalelioglu, Filiz; Adnan, Muge; Gulbahar, Yasemin; 0000-0002-7729-5674; AAF-8110-2019Teaching online requires different skills, roles and competencies for online instructors compared to teaching in traditional learning environments. Universities should offer ongoing support in various forms to help academic staff through their online journey. This paper provides insights into a multinational faculty development program for teaching online, elaborating on results of expectancy and satisfaction surveys. From a local program to a subproject within the Swiss National Science Foundation Project Scopes, e-Tutor aimed at expanding competencies in online lecturing and providing OER material for training colleagues. Designed in the form of a descriptive case study, this research was conducted with 34 attendees of e-Tutor. Data was collected using an e-learning readiness and expectancy questionnaire, and open-ended questions after the program to measure satisfaction. Descriptive statistics were used to analyze the survey data and content analysis for open-ended data. Participants considered e-Tutor a well-planned and targeted program with good theoretical and practical balance. Duration of such courses, opportunities for adaptation to real-life situations, and localization of the content are areas to be explored further. For future studies, it would also be interesting to see whether participants can apply their newly acquired knowledge and skills to create efficient online learning environments.
