Collaborations, Concepts, and Citations in Educational Technology: a Trend Study Via Bibliographic Mapping
(Springer, 2022) Soylu, Meryem Yilmaz; Akkoyunlu, Buket; Deryakulu, Deniz; Bardakci, Salih; 8539; 09.01. Ortak Dersler Bölümü; 09. Rektörlük; 01. Çankaya Üniversitesi
Research trends studies have emerged in education technologies (ET) to determine research manner and changes. Although the precedent examples dated back to the 1950s, trend studies within ET have gradually been increasing since the 1970s. This study aimed to examine the ET publications and research trends in a 5-year time period from 2014 to 2018. With a bibliographic mapping tool, namely VOSviewer, three research questions were addressed relating to collaborations, concepts, and citations in educational technology studies. The data set was extracted from ISI Web of Science databases and included 1690 articles published in six educational technology journals between 2014 and 2018. We used co-authorship analysis to determine the collaborating researchers' institutions and their geographical locations (countries) when they published the articles. A co-occurrence analysis was used to investigate concepts. Finally, a co-citation analysis was employed to determine the most cited papers and journals. Co-authorship analyses revealed that the number of articles published by researchers affiliated with institutions in the USA was the highest in the data set. According to co-occurrence analysis, online learning, especially in open learning environments, was the most studied concept. Moreover, co-citation analysis showed that the most frequently cited articles were published in Computers & Education. Additional findings, discussion, and limitations of the study were explained in the full text.
Developing and Validating a Rubric-Based Approach to Quality Assurance in Turkish Higher Education
(Pergamon-Elsevier Science Ltd, 2025) Akkoyunlu, Buket; Bardakci, Salih; Yildirim, Sibel Aksu; Avsaroglu, M. Dilek; Uludag, Gonca; Kocer, Ayhan; Elmas, Muzaffer; 09.01. Ortak Dersler Bölümü; 09. Rektörlük; 01. Çankaya Üniversitesi
This study, initiated by the Turkish Higher Education Quality Council (THEQC), develops and validates a rubricbased approach for evaluating institutional quality assurance (QA) processes within the Turkish higher education ecosystem. Effective quality assurance (QA) in higher education requires evaluation tools that are methodologically robust, responsive to institutional needs, and aligned with international benchmarks. A rubric-based approach offers a structured and transparent framework for consistent assessments. The rubric was created through an iterative, evidence-based process incorporating expert feedback, international benchmarks, site visits, and prior research. It consists of 22 main criteria across four key domains-Leadership, Governance and Quality; Learning and Teaching; Research and Development; and Service to Society-subdivided into 46 sub-criteria, each assessed on a five-point maturity scale. The validity and reliability of the rubric were rigorously examined. Content validity was established through evaluations by 10 QA professionals, addressing four key dimensions: relevance, alignment with the intended domain, appropriateness for the target audience, and clarity of language. Construct and criterion validity were assessed through consistency checks and usability analyses, with data collected from 252 external evaluators across 57 higher education institutions. Additionally, 360-degree feedback was gathered from both external evaluation teams and the institutions involved in the evaluation process. Results: demonstrate strong content validity (Lawshe coefficient =1.00, p < .05), high interrater consistency, and strong usability across various evaluator groups. Further evaluation confirmed the rubric's applicability and robustness across diverse institutional contexts. This study concludes that the developed rubric is a reliable and valid tool for enhancing and evaluating quality assurance practices in higher education.
