    Effect of multitasking and task characteristics interaction on cognitive load and learning outcomes in virtual reality learning environments
    (Springer, 2023) Tugtekin, Ufuk; Odabasi, Hatice Ferhan
    Learning environments are undergoing a dynamic alteration with the robust impact of technological transformation. Therefore, adapting to dynamic learning settings has now become a key criterion for academic performance. The factors that we know have a detrimental effect on learners' academic performance and cognitive capacity are related to today's traditional learning settings, but the circumstances in interactive learning environments such as virtual reality learning environments remains uncertain. To address this gap, we aimed to investigate the circumstances in virtual reality learning environments by considering both task characteristics and multitasking, both of which have been shown to have controversial effects on cognitive load and academic performance. The research was carried out with a total of 218 participants assigned to one of four treatment groups: (1) Multitasking & Regular Task (f = 59), (2) Multitasking & Hard Task (f = 56), (3) Monotasking & Regular Task (f = 52), and (4) Monotasking & Hard Task (f = 51), all with previous experience in virtual reality learning environments. Learners' working memory capacity and prior knowledge levels were measured as covariate variables. MANCOVA results showed significant differences across the treatment groups, in terms of achievement and retention scores. Findings not only reveal the more need for multifaceted empirical research in the field of education but also indicate that the outcomes of interactive learning environments may differ from those of traditional learning settings.

    Influential factors on academics' digital hoarding behaviours: an exploratory PLS-SEM research
    (Taylor & Francis Ltd, 2024) Tugtekin, Ufuk; Tugtekin, Esra Barut
    The transition to digital mediums among instructors, who are instrumental in shaping the higher education, streamlines and diversifies the instructional methodologies. Yet, it concurrently elevates the concern of digital hoarding behaviours to a prominent position in scholarly discourse. In view of digital hoarding's detrimental outcomes, the current study initially undertook a descriptive scrutiny of the digital hoarding behaviours among academics, subsequently correlating these tendencies with diverse factors. In addition, the study formulated and empirically tested a theoretical framework for understanding digital hoarding predicated on the employment of digital resources in academia. The research engaged 213 academicians voluntarily, with empirical evidence substantiating 13 of the 27 postulated hypotheses. The data indicated a predominant accumulation of text files among academics, alongside a tendency towards digital hoarding that surpasses the average. The outcomes of the PLS-SEM analysis, conducted to elucidate the justifications for digital hoarding, suggest that the level of experience of academics and the obstacles to digital data elimination exert a profound influence. It is imperative for the cultivation of a robust digitalisation culture within institutions, as well as the formulation and execution of data governance strategies, to involve all stakeholders, especially those within the academic sphere.
