“…There was also no interaction effect of question type and answer format on interest. Some reasons learners may pay more attention to open-ended questions include the concepts that this type of question (a) does not have a single correct answer (Goossen, 2002), so this encourages the person (Sobell & Sobell, 2008), and (b) may be answerable in part, if not known in full (Rogers, 1972;Lee, Kinzie & Whittaker, 2012). Also, since closed-ended questions have a single answer (Rogers, 1972;Lee et al, 2012), while open-ended questions seek multiple perspectives (Wragg & Brown, 2001;Jelly, 2001;Lee et al, 2012), open-ended questions might encourage learners to contribute more.…”
