“…Failure expectation expressions and other negative verbalisations of learning such as 'I don't understand', 'I can't get it' or 'I don't know' occur frequently in classroom interactions (Lindwall & Lymer, 2011). However, although these constructions are literally concerned with the students' ability or their level of understanding, the functions of these formulations vary (Beach & Metzger, 1997;He & Tsoneva, 1998;Lindwall & Lymer, 2011). In addition to showing non-understanding, claiming insufficient knowledge or asking for guidance from a teacher (Lindwall & Lymer, 2011), the formulations may be used for introducing a complaint (Depperman & Schmitt, 2008;Lindwall, & Lymer, 2011), resisting or avoiding on-going activity (Beach & Metzger, 1997;Hutchby, 2002;Lynch & Bogen, 2005;Metzger & Beach, 1996), implementing topic transition (Beach & Metzger, 1997) and expressing frustration over or criticising tasks (Deppermann, 2012;Lindwall & Lymer, 2011).…”
