“…To summarize, maximization of the engagement of students/learners in the educational procedure (a) can generate (i) motivation and stimulation of new perceptual skills and/or one's already obtained skills (e.g., soft skills, such as persuasive communication skills, versatility, critical thinking, emotional intelligence, etc.) (González-Salamanca et al 2020;Nicolaou 2019a) as well as (ii) more opportunities, challenges, and social benefits that will lead to enhanced learning outcomes, interaction, and interplay with the audiovisual media communications (Nicolaou et al 2019;Quinn 2018;Quinn et al 2016), and/or learner-learner interaction or enjoyment (Nagy 2018; Turan and Cetintas 2020); in addition, (b) it will aid in exchanging experiences and gaining access to best teaching practices (Frolova et al 2019), providing educational effectiveness in technology-enhanced learning. Furthermore, their efficiency can be strengthened if principles of theoretical frameworks, such as the theory of constructive learning (or constructivism theory) of von von Glasersfeld (1985) or the andragogy theory of Knowles (1989), are applied both to the content and the method of their development (see Nicolaou 2018a), and/or investigated through the technology acceptance model (TAM) (see, for example, Manolika et al 2021;Matsiola et al 2019;Fazil and Ward 2016) originally proposed by Davis (1989).…”
