“…As Burner (2014) puts it, "[i]t does not matter how productive PA [portfolio assessment] has proved to be if the students are not motivated" (p. 145). Furthermore, although PoBL has been implemented to promote various L2 abilities, including writing skill (e.g., Aliweh, 2011;Farahian & Avarzamani, 2018;Lam, 2013;Nicolaidou, 2013), speaking skill (e.g., Hung & Huang, 2016), reading skill (e.g., Charvade et al, 2012;Hosseini & Ghabanchi, 2014), and vocabulary learning (e.g., Sharifi et al, 2017), whether and how PoBL can be implemented for teaching L2 listening skill are relatively unknown.…”
