Some of the most popular ones investigated by researchers are learning management system (Bogdanović et al, 2014), student response system (Pérez-Segura et al, 2020), e-portfolio (Namaziandost et al, 2020), social media (Allagui, 2014), web 2.0 tools like blogs (Mohamed, 2016), wikis (Wang, 2014), Google Forms (Haddad & Youakim, 2014), selfassessment (Ishikawa et al, 2014), and peer-assessment (Chien et al, 2020). Qualitative studies focusing on teachers' use of OFA and related feedback strategies are, however, rare (Chen et al, 2020).…”
