“…In quasi-experimental studies with a pretest-posttest design, quantitative measures such as grammaticality judgments or correction tasks are used (e.g., Ammar, Lightbown, & Spada, 2010;Masny, 1997). More qualitative and descriptive measures include think-aloud protocols while conducting a task (Armengol & Cots, 2009;Swain & Lapkin, 1995), recorded interaction (Kiely, 2009;Kormos, 1999), learners' written notes about noticing (Edstrom, 2006;Hanaoka, 2007), or qualitative or retrospective interviews (Dégi, 2010). Each of these methods has its strengths and drawbacks concerning the completeness and quality of the collected data (for some discussion, see Bowles, 2010;Hanaoka, 2007).…”
