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 Snapshot of the First Implementation of Bebras International Informatics Contest in Turkey(2015) Kalelioglu, Filiz; Gulbahar, Yasemin; Madran, Orcun; 0000-0002-7729-5674; 0000-0002-1726-3224; AAF-8110-2019; AAG-6637-2020Computing was perceived as an essential skill for computer scientists, engineers, mathematicians and those from similar disciplines. 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 Mobile Learning in Higher Education Current Status and Future Possibilities(2015) Gulbahar, Yasemin; Jacobs, Carolyne; Konig, Andreas; 0000-0002-1726-3224; AAG-6637-2020Item Snapshot of Computational Thinking in Turkey: A Critique of 2019 Bebras Challenge(2022) Kalelioglu, Filiz; Dogan, Dilek; Gulbahar, YaseminThis study aims to provide a deeper understanding about the Bebras tasks, which is one of the computational thinking (CT) unplugged activities, in terms of age level, task category, and CT skills. Explanatory sequential mixed method was adopted in the study in order to collect data according to the research questions. The participants of the study were 113,653 school students from different age levels. Anonymous data was collected electronically from the Turkey 2019 Bebras challenge. Factor analysis was employed to reveal the construct validity to determine how accurately the tool measured the abstract psychological characteristics of the participants. In ad-dition, the item discrimination index was calculated to measure how discriminating the items in the challenge were. Qualitative data gathered through the national Bebras workshop was analysed according to content analysis. The findings highlighted some interesting points about the implica-tions of the Bebras Challenge for Turkey, which are discussed in detail. Furthermore, common problems of Bebras tasks are identified and possible suggestions for improvement are listed.Item Pedagogy of teaching introductory text-based programming in terms of computational thinking concepts and practices(2020) Kandemir, Celal Murat; Kalelioglu, Filiz; Gulbahar, Yasemin; 0000-0002-7729-5674Introduction Programming can be an intellectually satisfying skill and is definitely considered useful. However, problem-solving with a computer involves much more than just learning programming language syntax. The theory and practice are interrelated in fascinating ways. Whether one thinks that the purpose of college or higher education is to prepare students for an occupation or to develop foundational knowledge with lifetime benefits (or both), computer science (CS) has become a fundamental part of 21st-century life. Even students studying in areas other than CS are likely to have significant encounters with computational thinking (CT) later on in life. Motivation and Objectives Colleges and universities offer the opportunity for students to take as many courses as they desire in coding, programming, and CS taught by faculty members from that discipline area. However, this approach alone is deemed insufficient for computer-based problem-solving and computer programming. Effective programming teaching pedagogy also requires organizational principles that can guide us in formulating the overall design of a programming science curriculum (CS). In particular, we need strategies that help us structure multiple paradigm-based teaching curricula into manageable modules. This study aims to develop a framework for programming pedagogy. Research Methodology and Methods A systematic literature review was conducted for identifying, evaluating, and interpreting relevant research to explore programming paradigms that could be incorporated for novice programmers, possible implementation strategies, and instructional methods for teaching text-based programming, CT concepts, and practices. Results and Findings This paper's focus was on the pedagogical phenomenon of teaching programming considering the evolving paradigms, implementation strategies, and instructional methods and techniques through the lens of CT. Hence, a framework to design a learning path for pedagogical approaches that consist of CT concepts and practices within text-based programming were proposed. The proposed framework is based on the assumption that "any ongoing research on computing pedagogy requires a review of what CT is, how it impacts on teaching and learning and its role within the pedagogy advocated." The programming pedagogy framework consists of four fundamental components: programming paradigm, implementation strategy, instructional methods, and instructional techniques.Item 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.
