“…At this stage, the RBs provided in the course present as neutral, static and stand-alone artefacts that become available to all students in the same fixed order (except in Chapter 5 which offers choices). More research is needed to accommodate the RBs' nature (Bartholomé & Bromme, 2009;Stadtler & Bromme, 2008), modalities (Hung, Yang, Fang, Hwang, & Chen, 2014;Papadopoulos, Demetriadis, Stamelos, & Tsoukalas, 2009), exposure time (Gama, 2004), pattern of interaction (reading/watching information, giving information, verbalizing information, Saito & Interactive Learning EnvironmentsMiwa, 2007), learning event (Verpoorten, Poumay, & Leclercq, 2007) supported by the reflection (Kauffman, Ge, Xie, & Chen, 2008), role of tutors in the reflection process (Van den Boom, Paas, van Merrienboer, & van Gog, 2004), etc., to learners' individual characteristics (abilities, shortages, preferences, dispositions, acceptance of reflection, etc.) and content domains (Hoffman & Spatariu, 2008;Stark & Krause, 2009).…”
