“…However, the type of robot used influences the role that it may be given and how the learning material should be presented (i.e., the teaching strategy), and this is further related to the learners' age. Some previous studies have considered different types of educational robot hardware and software (Han, 2012;Mubin, Shahid, & Bartneck, 2013a;Randall, 2020), teaching strategies and underlying pedagogical theories (Mubin, Stevens, Shahid, Al Mahmud, & Dong, 2013b;Wu, Wang, & Chen, 2015), the role of the robot in the practice (Aidinlou et al, 2014;Han, 2012;Mubin et al, 2013b) and learner age groups (van den Berghe et al, 2019), but this article expands on the question how different robot types should be combined with different teaching strategies and robot roles, in general, and for adults in particular. Belpaeme et al (2018) described similar considerations for preschool children, but since there are few previous RALL studies with adult learners, the goal of the literature survey is to answer the question: What conclusions for RALL for adults can be drawn from how robot type, teaching strategy and robot role have been combined for different learner age groups in previous studies?…”
