- ItemOpen AccessAutomated Essay Scoring (AES) Systems: Opportunities and Challenges for Open and Distance Education(2022-09) Bai, John Y H; Zawacki-Richter, Olaf; Bozkurt, Aras; Lee, Kyungmee; Fanguy, Mik; Cefa Sari, Berrin; Marin, Victoria IPCF10 Sub-theme: Inspiring Innovations // This paper reports on a systematic review of artificial intelligence applications in education (AIEd) with a special focus on automated essay scoring (AES) systems. AES systems may provide enormous time-savings, especially for large-scale distance teaching institutions with massive numbers of students, by reducing marking and freeing up teachers’ resources for individual feedback and personal support of distance learners. After an introduction on how AES systems function, a review corpus of published articles between 2007 and 2021 is synthetised to evaluate critical discussions and research trends in AES. Articles in the corpus generally evaluated either the accuracy of AES systems or the experience of users, and include implementation of AES systems in various settings (i.e., higher education, K-12, and large-scale assessments). Despite the opportunities that AES might afford for educational institutions, many questions related to the feasibility and validity of AES systems, their implementation, and the associated ethical issues are still unanswered. The findings of this research provide a solid foundation for this discussion. // Paper ID 8339
- ItemOpen AccessDiscourses of Distance Education and Covid-19 in South Korean News between 2019 and 2021: A Topic Modeling Analysis(2022-09) Lee, Kyungmee; Kim, Tae-Jong; Bozkurt, Aras; Zawacki-Richter, Olaf; Sari, Berrin Cefa; Marin, Victoria IPCF10 Sub-theme: Promoting Equity and Inclusion // This paper aims to identify dominant discourses of distance education that emerged in Korean society before, during, and after the Covid-19 outbreak in January 2019. To achieve the aim, the authors have conducted a Topic Modeling analysis of 8,865 news articles published by 54 South Korean media outlets between 2019 and 2021. As a result, five key topics and the top 10 keywords associated with each topic have been identified for 2019, 2020, and 2021, respectively—15 topics and 150 keywords in total for the three years. There have been meaningful shifts not only in the quantity of news articles published each year but also in the quality of conversations presented in those articles on distance education. This article carefully analysed and reflected both continuity and discontinuity of distance education discourses in Korean society. Based on the results, we have drawn four discussion points: a) the normality of DE discourses, b) the historicity of DE discourses, c) the maturity of DE discourses, and d) the partiality of DE discourses. Despite the specific cultural context from which the four points were drawn, the discussions offer valuable insights applicable to different cultural contexts. // Paper ID 8809
- ItemOpen AccessThe State of the Art in Blended Learning Research in a Time of the Covid-19 Pandemic: Coronavirus Diaries in the Educational Realm(2022-09) Bozkurt, Aras; Marin, Victoria I; Lee, Kyungmee; Cefa Sari, BerrinPCF10 Sub-theme: Building Resilience // The Covid-19 pandemic was a crisis on a global scale, and it impacted not only our lives but also our understanding of the educational landscape. There were many waves of the pandemic at varying levels and as these waves hit our globe, the way we live and see the world has been changing. Consequently, we entered a time which was called the new normal which required being flexible, resilient, and adaptive. The educational landscape has also been challenged by the waves of the pandemic. The onsite (face-to-face) learning was replaced by online distance learning which was attributed as emergency remote teaching and learning in many cases. As the new normal forced us to change our traditional notions and practices, many higher education institutions adopted blended learning to benefit from opportunities of both modalities, that is, onsite and online learning. In this regard, this study implements a systematic approach to examine papers published in the first two years of the pandemic on blended learning. For this purpose, the study adopts social network analysis and text mining to examine a total of 104 peer-reviewed publications. The initial findings identified four broad themes. Accordingly, these are (1) diversity and confusion in the blended learning terminology, (2) Learning experiences and effectiveness of blended learning practices, (3) technology-dominated and online-mediated blended learning approaches, and (4) blended learning for applied and practical courses. The paper discusses these themes, provides suggestions, and explains implications for future research directions. // Paper ID 6418
